Core Technology Becomes Industry Support
In 1958, with the successful commissioning of a 1,000 tonne/year neoprene industrialized plant at Chongqing Changshou Chemical Plant, China produced the first synthetic rubber neoprene in history. This is the first synthetic rubber product with independent technology in China. After continuous improvement and improvement, a 10,000-ton neoprene production technology with a complete safety and environmental protection system and an automation operating system has been formed.
Nickel polybutadiene rubber is a type of synthetic rubber with complete independent intellectual property rights in China. Since Yanshan Petrochemical Company's first 15,000 tons/year plant was put into operation in 1971, it has successively built and produced production facilities in seven domestic companies. With a total capacity of 445,000 tons, it is the world's second largest producer after the United States, and accounts for 14.5% of the world's total capacity. The technology has the advantages of high catalytic activity, strong adaptability, low toxicity of the used solvent, large capacity of the polymerization vessel, large production strength, and long continuous operation period.
SBS has now become the third largest synthetic rubber product in the country after sales and sales of SBR and polybutadiene rubber. In 2004, the output reached 243,000 tons, and the consumption was about 440,000 tons. It has entered the ranks of the world's largest consumer of SBS, and the domestic market share has increased from 36% in 1999 to 56% in 2004, fully demonstrating the market for domestic technology. Competitive Advantage. In addition, the SBS industrial production technology developed in China was transferred to Italian Enichem Elastomer Company and China Taiwan Synthetic Rubber Corporation in 1986 and 1991 respectively, which ended the history that China's petrochemical industry had only export without export.
In addition, in our country's introduction of synthetic rubber products, after years of digestion and absorption and innovation, has also formed its own technical characteristics. If SBR is innovatively developed based on the introduction of technology, it has formed its own unique technology and has the ability to develop new, market-applicable brands.
The six major industrial bases have their own characteristics
In the late 1980s, China only produced polybutadiene, styrene-butadiene, nitrile, and neoprene. Since the 1990s, domestic and imported technologies have been used to build SBS, ethylene-propylene rubber, butyl rubber, and nitrile-butadiene soft rubber production facilities. Basically, a relatively complete synthetic rubber variety system has been formed, and 6 bases with an annual output capacity of over 100,000 tons have been formed. Each of these six bases has its own characteristics and accounts for 75% of the country's major rubber seeding capacity and 78% of its output.
Yanshan Petrochemical Company has four major products, namely polybutadiene rubber, SBS, butyl rubber and solutionized styrene-butadiene rubber, with an annual production capacity of 240,000 tons, ranking fifth in the world. It is the largest synthetic rubber production and export base in China. . Qilu Petrochemical Company has two major varieties, namely SBR and polybutadiene rubber, with an annual production capacity of 170,000 tons. The annual production capacity of SBR is 130,000 tons, making it one of the 13 largest plants in the world. It is also the company with the largest number of domestic oil-filled plastics. Jilin Chemical Co., Ltd. has three major products, namely SBR, EPDM and nitrile rubber, with an annual production capacity of 170,000 tons. It is the only EPDM rubber manufacturer in China. Baling Petrochemical Co., Ltd. has two major products, SBS and polybutadiene rubber, with an annual production capacity of 150,000 tons. Its SBS production capacity ranks third in the world. It is also the largest production base with the largest number of SBS series and the largest capacity. Product development capabilities. Nantong Shenhua Chemical Co., Ltd. has an annual production capacity of 120,000 tons of SBR, and it is a controlling joint venture of China Taiwan Synthetic Rubber Company. Gaoqiao Petrochemical Company has an annual production capacity of 100,000 tons of polybutadiene rubber, ranking the ninth in the world. At the same time, it is also the largest domestic producer of styrene-butadiene latex.
Development market still needs to be strengthened
Although China has basically formed a relatively complete series of synthetic rubber products, there is still a large gap compared with market demand. For example, the product structure still needs to be further adjusted and optimized; some varieties still lack independent core technologies; the equipment capacity is insufficient, and the market share is low.
To this end, China Synthetic Rubber Industry Association has three suggestions: First, the development of synthetic rubber complete sets of technology is a systematic project. It is difficult for a single enterprise to realize the entire process from scientific research to industrialization. It must rely on the support of the state and concentrate national strength to develop large-scale synthetic rubber sets. Production technology; Second, the current domestic introduction of synthetic rubber technology, especially the key technology is very difficult, the domestic monopoly companies should take into account the long-term strategic interests, come up with a part of human, material and financial resources, develop synthetic rubber complete sets of technology; Third, synthetic rubber production enterprises should On the existing basis, the existing technology will be further improved, and sporadic technologies will be integrated into complete sets of technologies.
Industry Focus on Synthetic Rubber Industry: Autonomous Technology Occupies Half of the Industry
As the world's largest importer of synthetic rubber, China's rubber market has a huge consumer potential, so that China has a pivotal role in the world's synthetic rubber industry, but also stimulated the rapid development of China's synthetic rubber industry. Through domestic self-reliance, independent research and development and the introduction of world advanced technology, China's synthetic rubber industry has formed an important industry with a complete product system and an annual output of over one million tons. At present, all the seven basic rubber types of synthetic rubber have formed industrial production capacity except for isoprene rubber. In 2004, China's total synthetic rubber capacity reached 1.4 million tons, ranking fourth in the world after the United States, the Commonwealth of Independent States, and Japan; its output was 1.37 million tons, ranking third in the world; and apparent consumption reached 2.38 million tons. , ranking first in the world.
