Another step has been taken in the industrialization of isoprene rubber for tires

July 26 is a special day for researchers of Jilin Petrochemical Research Institute. Why do you say so? As a veteran of the industry, a colorless and translucent rubber block was removed from the compressor block by block, which means that the industrial model test of isoprene rubber production technology development, a key scientific and technological development project of China National Petroleum Corporation and the science and technology support program of the Ministry of science and technology of the people's Republic of China, has been basically completed, The development of isoprene rubber production technology with completely independent intellectual property rights in China has taken another important step towards industrialization. The instrument uses digital display and can automatically print test results and data and processing

it is understood that the production of plastic products with required properties by adding different fillers, plasticizers and hardeners in this model test is another substantive progress made by Jilin Petrochemical Research Institute after completing the design of 1000 ton isoprene rubber industrial test device and starting the design of 50000 ton process software package. The quality of isoprene rubber is graded according to the application field. The products developed and produced in China are mainly used in medicine and gaskets, and the conversion rate is not high. Isoprene rubber for tires has the highest quality requirements. It is the product of this specification developed by Jilin Petrochemical Research Institute

Dr. Bai Chenxi, the project manager of the project, told that the isoprene rubber developed by Jilin Petrochemical Research Institute in cooperation with the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences had been tested by the national electrochemical and Spectral Research and Analysis Center, and the product quality met the requirements of isoprene rubber for tires. At the same time, the two sides also cooperated to carry out tire trial production and bench test. According to the testing and evaluation of the material testing and research center of China Rubber Industry Association, the testing data are basically the same as that of natural rubber and foreign products. The Institute is currently carrying out the second stage of tire formula optimization design test, looking forward to new breakthroughs in product technical indicators

he introduced that the most advanced isoprene rubber production technology in the world adopts rare earth catalytic system. As early as the 1970s, Jilin Petrochemical Research Institute cooperated with Changchun Yinghua Institute to develop the internationally advanced isoprene rubber production technology at that time. In 2006, the two sides once again jointly developed a new and internationally pioneering rare earth isoprene rubber catalytic technology, and successfully solved many key problems affecting product quality. Since this year, they have carried out a large number of tests on the 20 liter continuous polymerization model test, including Moscow, Leningrad and Voronezh devices. So far, they have completed eight long-cycle and stability evaluation tests, operated stably for 1500 hours, and obtained 2000 kg of test products

according to Wang Xunzhang, President of Jilin Petrochemical Research Institute, when isoprene rubber production technology was successfully developed as early as the 1970s, the total amount of domestic C5 had not reached the economic scale, and the source of raw material isoprene could not be solved. Now, according to the "12th Five Year Plan" development strategy, the resources of C4 and C5 in Northeast China of PetroChina will be gathered in Jilin Petrochemical for processing, which can provide sufficient raw materials for the industrial production of isoprene rubber
