Recently, from the "green tire" processing company - Shandong Jinyu Tire Co., Ltd. came a message, in 2013 the company produced more than 500 million high-performance tires into the high-end markets in Europe and America, an effect of nearly 1 billion. In this “Green Tire†relay race, which was supported by research institutes such as PetroChina Research Institute of Petroleum and Petrochemical Technology and Qingdao University of Science and Technology, a number of domestic manufacturers jointly participated in the “green tire†relay race.
The development of “green tires†to realize industrial upgrading is a major trend in the development of the tire industry in the world. However, many tire companies in China are at the low end of the international tire manufacturing industry chain. They have accelerated the “green tire†process from the aspects of raw materials, processing technologies and formulas, etc. One of the key points in the transformation and upgrading of the rubber industry.
Comparing with the first rubber grade latex styrene-butadiene rubber, the solution-polymerized styrene-butadiene rubber has the characteristics of environmental protection, cold resistance, low heat generation, low shrinkage, and high vulcanization speed. It also has small rolling resistance and wet skid resistance. With excellent wear resistance and other advantages, it is called "Pearl on the styrene butadiene rubber crown" and it is also an excellent raw material for the production of "green tires." However, domestic dissolvable styrene butadiene rubber still needs to be improved in terms of properties such as dispersibility, coupled with insufficient understanding of the advantages of butylbenzene in the processing of rubber products, so that this product can only be used in footwear and other fields.
To break through the technical bottleneck of the application of SBR in tires as quickly as possible, China Petroleum and Chemical Research Institute and Dushanzi Petrochemical Company faced difficulties and took the responsibility of the “national team†of scientific and technological advancement. Applications for high-performance radial tires.
In order to achieve a breakthrough in this project as soon as possible, researchers from the Petrochemical Institute stepped out of the laboratories, in-depth production line and processing companies and excellent companies that prepared high-performance tires and raw material product manufacturing companies to work together, set up to take the lead in the petrochemical industry, integration of domestic dissolved In the styrene-butadiene-rubber field, the company has established a cooperative research and technology innovation team consisting of Sinopec, Jinyu Tire, Haida Rubber and Qingdao University of Science and Technology.
Tsinghua Petrochemical, with a production capacity of 100,000 tons/year of polymerized styrene-butadiene rubber, systematically studied catalyst, structural regulator, random agent, coupling agent, and terminator technology to overcome the key to synthesizing SSBR for high performance tires. Polymerization technology ultimately makes the key indicators and performance of the product equal to foreign mainstream products, and has mastered the key technology of mature and stable industrial production; Petrochemical Institute and Qingdao University of Technology have developed a solution to the high-energy of synthetic rubber and developed a solution of styrene-butadiene rubber. The controllable forming technology and process for preparing tires, the low-temperature mixing technology of polybutylene styrene, the carbon black-silica black double-phase reinforcing technology, and the SSBR/BR/SBR combined technology. After conquering a difficult technical road, innovative cooperatives began to enter the new battlefield where they dissolved butadiene-styrene rubber to make "green tires."
After hundreds of experiments and fine processing of thousands of batches of data, the process and formula for the preparation of "green tires" by solution polymerization of styrene-butadiene rubber were finalized. At Jinyu Tire Co., Ltd., the completion of the “green tires†with polybutadiene-butadiene rubber was completed. The high-grade tires produced by Jinyu Tire have successfully entered the European and American markets. Due to its environmental protection, excellent wet skid resistance, low rolling resistance, and remarkable energy-saving effect, Jinyu Tire has become a matching tire for high-end cars, racing cars, and special vehicles that adapt to low-temperature ice and snow conditions in winter. Under the background of fierce competition in the domestic market, Jinyu high-end tires have become the "bright spot" for China's synthetic rubber industry to rely on technological progress in the international market competition.
At the same time, with the active promotion of PetroChina and the support of the advanced technology of the Petrochemical Institute, the domestic production of SBR has also made considerable progress. In the case of the conversion of the same type of domestic equipment to SBS high elastomers, the independent petrochemical 100,000 metric tons/year solution butadiene styrene butadiene rubber plant went against the market and the rubber output steadily increased. The total sales volume increased from 7,000 tons in 2011 to 2013. 50,000 tons, reducing production costs and enhancing product competitiveness.
