Prospects for the Tenth Five Year Plan of China's rubber industry

current situation of China's rubber industry at present, there are more than 4000 production enterprises in China's rubber industry, forming a relatively complete industrial system of 10 professional categories, such as tires, bicycle tires, rubber hoses, tapes, rubber shoes, rubber products, latex, reclaimed rubber, tire retreading and related additives, with product varieties of 18 categories and more than 50000 specifications

many important changes have taken place in China's rubber industry in the past 20 years. Performance: the product structure has been adjusted. Taking radial tires as an example, a total of 28.42 million sets of radial tires were produced nationwide in 1999, accounting for more than 35% of the total tires in response to the green manufacturing partnership initiative. While solving the production technical problems, the conveyor belt focuses on adjusting the product structure, so that the content of the domestic flame retardant conveyor belt covers more than 40 claims, such as the new alloy composition design, the whole process manufacturing and processing technology, and the quality level and production capacity can be improved. At present, the output of non combustible conveyor belts has accounted for 30% of the total output of rubber conveyor belts, which basically meets the needs of the coal industry. In the carbon black industry, breakthrough progress has been made in the production of new process carbon black, and enterprises have begun to carry out structural adjustment around products dominated by new process carbon black. Other products, such as rubber shoes and rubber products for automobiles, have also undergone fundamental changes in product quality, product grade and added value. The production of latex products also maintained rapid development

the enterprise structure has changed. With the deepening of China's reform and opening up and the establishment of a market economy, rubber conglomeration and joint-stock transformation have developed rapidly, and private and foreign-funded enterprises have increased rapidly. At present, there are 7 listed companies in rubber enterprises, including 5 domestic listed companies and 2 overseas listed companies. While major adjustments have taken place in domestic rubber enterprises, foreign-funded enterprises and private enterprises have developed. According to preliminary statistics, 30% of the major tire production enterprises have joint ventures with Hong Kong businessmen and foreign businessmen. Foreign joint ventures include Michelin, Goodyear, Shiqiao and other world-famous multinational companies. In the rubber products industry, Phoenix, gates, Goodyear, Shiqiao, Hutchinson and other well-known rubber products companies also set up joint ventures or wholly-owned factories in China. Foreign funded enterprises and private enterprises in rubber shoes have occupied a dominant position in the market

the progress of technology and equipment has accelerated. The rubber industry has improved the overall technology and equipment level through technological transformation and the introduction of technology and equipment

tire industry: bias ply tires have been comprehensively transformed into high-quality and light-weight tires. Large capacity internal mixer is widely used in large and medium-sized tire manufacturers. Tension calendering is basically realized for cord calendering, and "three sides and four pieces" compound extrusion is realized for tread extrusion. The molding is gradually controlled by procedures. The introduction of radial tire production technology and major key equipment has rapidly improved the level of production technology and equipment in this regard

hose and tape industry: the production technology and equipment of high-pressure steel wire braiding and winding hose and high-pressure resin hose with the world's advanced level, as well as the production technology and equipment of flame retardant conveyor belt and high-strength steel wire rope conveyor belt have been introduced, which has greatly improved the technical equipment level of China's hose industry, and the hose products basically meet the domestic market demand

although China's rubber industry has developed to a considerable scale, there is still a big gap compared with the foreign advanced level, especially in scientific research and innovation, new product development. Performance in:

first, the production cost is high. Take radial tire as an example. At present, this product is in the growth period in China, with relatively large production investment and relatively small scale, resulting in high production costs. According to statistics, the production efficiency of China's key tire enterprises is 1/5 and 1/8 of that of the United States and Japan respectively

second, the investment in science and technology is small, and the ability of scientific research and development and product innovation is poor. The number of invention patents of major foreign companies is large, such as more than 3000 patents in the rubber industry in Japan every year. In addition, they do not hesitate to spend a lot of money on some major topics, such as Pirelli's research and development of high-performance p6000 radial tires, with an investment of US $50million. According to Michelin, its scientific research and development expenditure reached nearly 700 million US dollars in 1999. There are few innovative achievements in scientific research and development of domestic enterprises. In the 10 years from 1985 to 1995, there were only more than 600 patents in the rubber industry, which was far behind that of developed countries

third, the quality competitiveness is relatively weak. According to the comprehensive mileage of bias truck tires, it is 200000 kilometers in developed countries and only about 100000 kilometers in China. The tread running temperature of Bridgestone bias truck and light truck tyres in Japan is 10 ℃ and 9 ℃ lower than that of domestic tyres respectively; The radial truck tire and car tire of French Michelin company are 8 ℃ and 12 ℃ lower than domestic tires. The standard life of domestic conveyor belts is 500000 tons, and the products of developed countries are more than 2million tons. The service life of V-belts used in combine harvesters is only about 100 hours for most domestic ones, and 500 ~ 2000 hours for developed countries to adopt proportional electromagnets as electrical 1 Mechanical converters. The service life of oil seal made in China is 50000 ~ 80000 km, and the service temperature is below 120 ℃; Imported products reach 100000 kilometers, and the service temperature can reach 150 ℃ ~ 200 ℃

fourth, high-tech products account for a small proportion. The proportion of radial tires in China's output was only 23% in 1998, while that in Europe and the United States was more than 95%, that in Japan was 92%, and that in South Korea was 85% of the code for acceptance of construction quality of concrete structures GB 50204 ⑵ 002. In terms of radial tire specifications and varieties, China currently produces only nearly 200 specifications and varieties, mainly focusing on a few specifications, and the product convergence rate is high. Michelin has 3500 specifications and varieties. New varieties, such as waterproof and slippery tires, ultra-high mileage tires, ultra lightweight tires, and tires for safe running, have not yet been studied in China

market prospect of China's tires and rubber products. Due to the impact of the Asian financial crisis, the current automobile demand growth is not fast, and the output growth slows down. The automobile output in 2000 was 2.06 million, an increase of 12.5% over 1999. The estimated output this year is 2.2 million to 2.3 million vehicles. During the period from 2001 to 2005, the demand for automobiles is expected to increase rapidly. The output in 2005 is expected to reach 2.9 million to 3 million, including 1.1 million to 1.25 million sedans. It is estimated that the total demand for tires is 135million

automotive rubber products automotive rubber products are important auto parts. There are 400 ~ 500 rubber products on each car, weighing about 40 kg (excluding tires), and 14 kinds of rubber are commonly used. At present, there are more than 1200 varieties and 8500 specifications of domestic automotive rubber products. In terms of rubber consumption, 60% are tires, and 40% are all kinds of rubber hoses, tapes, oil seals, sealing strips, damping blocks, etc. According to the "Tenth Five Year Plan" for the development of the automotive industry in the machinery industry and the requirements for automotive rubber accessories, the demand for automotive rubber accessories in 2005 is expected to be as follows: 72.2 million standard meters of automotive rubber hoses, 83 million V-belts for automotive use, 124 million oil seals for Automotive frameworks, 19.8 million synchronous toothed belts and multi wedge belts for automotive use, 90.8 million meters of composite sealing strips for automotive use, and 41.27 million other fine rubber accessories for automotive use. In 2000, automobile rubber products consumed about 150000 tons of various rubbers

at present, the annual production capacity of rubber hoses in China is 200million standard meters, and the output can basically meet domestic demand. It is estimated that the demand for rubber hoses in China in 2002 will be 178 million standard meters, with an average growth rate of 2.3% in the past two years

the demand for conveyor belts in major industries is expected to be 95million square meters in 2005. Among them, the proportion of conveyor belts in coal, metallurgy, ports, chemicals and building materials is 33%, 25%, 22% and 12% respectively, and other conveyor belts account for 8%

future development priorities of China's rubber industry during the Tenth Five Year Plan period, the development priorities of China's rubber industry are radial tires, products supporting pillar industries and export products. We should focus on improving the grade and quality of products and the level of production technology. It is estimated that by the end of the tenth five year plan, the consumption of rubber will exceed 2.4 million tons in 2005, and the application proportion of synthetic rubber will increase from about 48% to 55%. The output of main products is expected to reach 125 million tires, including 56 million radial tires. The grade of rubber products will be significantly improved, and the level of production technology will be greatly improved. While developing production technology, we will pay attention to developing economies of scale, promoting mergers and acquisitions of enterprises, promoting the development of large enterprises and enterprise groups, and enhancing the competitiveness of enterprises in domestic and foreign markets. At the same time, we should actively, reasonably and effectively use foreign capital and develop foreign exchange and cooperation. Driven by the development of the rubber industry, supporting industries such as rubber machinery, rubber raw materials, framework materials, additives, carbon black and molds will also develop accordingly

the development focus of tire industry is radial tire. Car tyres should be tubeless and flattened to improve the processing accuracy of radial tyres. Focus on the development of 65, 60, 55, 50 series of S, t, H-class products, and appropriately develop 50, 45 series of V, z-class high-performance passenger car radial tires. Truck tire development tubeless truck tire. On the basis of improving the comprehensive quality level, the bias tire should focus on improving the speed performance and one-time driving mileage

motorcycle tires develop low profile motorcycle tires, focusing on S-class 70 series motorcycle tires and ultra-thin series tires. We should speed up the development of tubeless motorcycle tires and radial motorcycle tires

bicycle tires should focus on developing export products of bicycle tires, and should organize technical transformation focusing on high-quality and lightweight, so as to reduce raw material consumption and improve economic benefits

rubber products develop fine rubber products supporting automobiles, machinery, household appliances and modern office supplies. The focus is on new air conditioning pipes, oil delivery pipes for automobiles, skeleton oil seals, door composite seals and combined seals produced by new rubber materials such as hydrogenated nitrile rubber, fluororubber and chlorohydric rubber

the main tasks of the "Tenth Five Year Plan" of rubber overshoes and rubber overshoes industry are product development and innovation, increasing the variety of designs and colors, improving the grade of products, increasing the proportion of medium and high-end shoes, creating international brands and developing export products

the industry of rubber hose and belt mainly focuses on further adjusting the product structure. Conveyor belts focus on low smoke, low toxicity and flame retardant belts above grade 8, impact resistant steel wire rope flame retardant belts, and tropical and light conveyor belts for metallurgy and chemical industry. Rubber hoses focus on the development of special drilling rubber hoses for oil fields, large-diameter oil delivery rubber hoses on the sea, mechanical hydraulic transmission rubber hoses and special rubber hoses for automobiles
