According to Qi Runtong, the secretary general of the China Synthetic Rubber Industry Association, the international giants have adopted more technical blockades on advanced synthetic rubber technologies and relying on imported technology to significantly increase the level of domestic synthetic rubber is not realistic. The shortage of synthetic rubber must be developed independently. However, in the past, there were few exchanges between synthetic rubber companies and tire companies, and they were unable to understand the latest progress and development of each other in a timely manner, and it was difficult to directly improve the quality of products based on user feedback. This time PetroChina, Sinopec's subordinate enterprises and research institutes, and private synthetic rubber companies and domestic major tire companies exchanged their respective new trends and expectations for each other's companies, which is a good start for cooperation and development. Now PetroChina and Sinopec have invested a great deal of effort in developing new synthetic rubber independent technologies. These new varieties need to be improved, and tire companies need to make suggestions for improvements to better promote technological progress. In the future, the two associations will further "bridge" companies and jointly promote the development of national brands.
“Most of the materials used in tire processing are known, but it is not clear how the synthetic rubber is applied to the tires. The formula of the tire company has not changed in the past years, and the formula is now adjusted to the price of raw materials. How can a synthetic rubber company meet the requirements of tire companies?†A statement made by a representative of PetroChina once resonated with the opening.
“In China, both Gaoqiao Petrochemical and Dushanzi Petrochemical can produce SBR, but their products are very different. Different grades have different styrene and vinyl content, and their specific parts are different. The market is not. Similarly, increasing the vinyl content can reduce tire heat generation, but it has no effect on improving wet skid resistance, increasing the content of styrene and improving wet skid resistance, but when the styrene content is too high, the heat generation will be greatly increased. Solubility polymerization of styrene-butadiene rubber is a big issue, and now it has been developed to the fourth generation of products in the world. The application of domestic polybutadiene-butadiene rubber is not a lot of applications. Both parties should study this issue well." Hangzhou Zhongce Rubber Co., Ltd. radial tire Ren Fujun, deputy director of the research office, said.
"Linglong's export of winter tires has been used in the solution of styrene-butadiene rubber, but now the purchase of foreign companies' products, hoping to get the same quality of domestic raw materials as foreign companies as soon as possible. In addition, we also want to try integrated rubber, etc. New synthetic rubber, and domestic companies in the formulation, process and other aspects of the full cooperation." Shandong Linglong Tire Co., Ltd. Deputy Chief Wang Zujian said.
"Yanshan Petrochemical has produced 80 tons of integrated rubber, processing performance is close to raw rubber, excellent wet skid resistance. Now the process conditions of integrated rubber are already available, ready to trial production. 30,000 tons / year process package design Completed, three grades of random type integrated rubber and corresponding vulcanization system have also been developed.In the past, we did not understand the tires deeply, and we especially hoped to have in-depth exchanges with exquisite, Chinese strategy, double money and other tire companies, and also welcome everyone. Try our new products.†To hear people interested in integrated rubber, Yu Guozhu, deputy director of Yanshan Branch of the Sinopec Beijing Research Institute of Chemical Industry, could not wait to introduce them.
“Chlorinated butyl rubber and bromobutyl rubber are still monopolized by two major international giants. The price of halogenated butyl rubber in June exceeded 60,000 yuan per ton. Some companies have to change their prices due to cost pressures. Benzene rubber instead of. We hope that halogenated butyl rubber can be produced industrially as soon as possible, and we hope that domestic synthetic rubber companies will provide more cost-effective materials for tire companies," said a representative of Qingdao Double Star Tire Industry Co., Ltd.
“The first domestic brominated butyl rubber plant was completed at Sinopec Beijing Yanshan Branch in May of this year. It was commissioned at the end of July and its design capacity was 30,000 tons/year. Not only was the bromobutyl rubber product developed, Yanshan Petrochemical was also established. In addition, Yanshan Petrochemical also conducted a batch polymerization study of ethylene-propylene-rubber, preliminary completion of the synthesis of ethylene-propylene-diene rubber grade, and it is expected to be industrialized in 2014; a 30,000-tonne/year RE The complete set of technology for the production of butadiene rubber industry is expected to be completed and put into operation in 2012; a 30,000 tonne/year rare earth isoprene rubber industrial production complete set of technology will be completed and is expected to be completed and put into operation in 2013. Sinopec Qilu has independently developed environmentally friendly oil-filled styrene-butadiene rubber, Highly-binding styrene-butadiene-styrene (SBR) can also increase tire weight for tire companies to meet EU standards.†Liang Aimin, director of Yanshan Branch of the Beijing Research Institute of Petrochemical Technology, said, “Yanshan Petrochemical is willing to conduct trial production of new products for tire companies at any time. It also invited tire companies to analyze foreign products together, and for tire companies that do not have testing conditions, the testing center will also give preferential tests.
At present, China Petroleum Karamay Petrochemical Company and Liaohe Petrochemical Company's environmental protection rubber oil has reached the EU standard, Karamay cycloalkyl rubber oil product quality has reached the international advanced level; April 22 this year, China's first set of isoprene rubber device In Maoming Luhua Chemical Co., Ltd. put into production, the annual output of 15,000 tons of equipment will produce qualified products on April 26. Jilin Petrochemical and Changchun Yinghua Institute have successively developed polyisoprene rubber synthesis technology for titanium and rare earth catalyst systems. And has entered the pilot phase. Liu Jie, deputy chief economist and senior engineer of China National Petroleum Corporation’s refining and chemical division, said that with the implementation of REACH and other laws and regulations, it has now entered a new era of environmental protection and energy conservation. CNPC hopes to work closely with tire companies to jointly accelerate the development of new high-performance synthetic rubber products and increase the core competitiveness of domestic companies.
Synthetic Rubber Marriage Tire Figure Strong National Industry
“We would like to provide tire companies with new synthetic rubber products for trial at zero prices!†“In the future, we will invite more tire experts to discuss how to effectively track new technologies in international tires and materials!†“For tire companies, Synthetic rubber is not only the problem you produce for me, but it is the best way to jointly research how to make good use of deep-seated cooperation!"......In the last week, the domestic tire synthesis was jointly organized by China Synthetic Rubber Industry Association and China Rubber Industry Association. At the Rubber Market Development Symposium, synthetic rubber manufacturers and tire companies came together to explore new models for upstream and downstream cooperation and development. Both parties expressed their desire to cooperate in all aspects, especially in the areas of energy-saving and environmentally friendly new products, new technologies and high-performance materials, in order to increase the independent competitiveness of domestic synthetic rubber companies and tire companies, promote product upgrading, and jointly expand production. Stronger national brand.
