New chemical materials: technological breakthroughs to achieve great industries

During the "11th Five-Year Plan" period, China's chemical new materials industry has developed rapidly and has initially formed a new category of chemical industry. The successful development of several key technologies in the fields of engineering plastics, film materials, fluorosilicone materials, and synthetic rubber has further strengthened the development potential of the new chemical material industry.

Statistics show that in 2009, China's chemical materials sales in the domestic market were about 105.9 billion yuan. It is expected that in 2010, the scale of China's chemical new materials market will reach more than 200 billion yuan.

The implementation of a number of high-tech projects such as the "863" plan has enabled China's engineering plastics to make a number of breakthroughs during the "Eleventh Five-Year Plan" period. The Polyetheretherketone resin project completed by Jilin University won the second prize of National Technological Invention Award in 2009. This project has designed and synthesized 4 specific monomers of new structure and 3 series of high-performance high-temperature resistant thermoplastic resins, breaking the long-term technical ** in our country and satisfying the urgent needs of domestic military and high-tech fields. Bluestar Chemical New Materials Co., Ltd. has developed polyphenylene ether production technology with international advanced level through introduction, digestion, absorption and re-innovation, and built China's first large-scale polyphenylene ether industrial device with an annual output of 10,000 tons. Sichuan Deyang Science and Technology Co., Ltd. broke through the key technology of engineering, and has already formed a production scale of super-million tons of polyphenyl ether resin, which can produce plastic grade polyphenylene ether resin products. The Changchun Yinghua Institute of the Chinese Academy of Sciences and Gansu Yinguang Juyin Chemicals Co., Ltd. jointly developed a new 500-ton polycarbonate industrialization technology with independent intellectual property rights, which filled the gap in the production of polycarbonate technology in China. .

Perfluorinated membrane is the core material of chlor-alkali industry. It can be said that it is the bottleneck of the safe operation and healthy development of China's chlor-alkali industry, and it is also a major technology that China's chemical industry is determined to overcome. During the “Eleventh Five-Year Plan” period, China has fully mastered the preparation technology of perfluorinated membranes, and in September 2009, it created the first membrane with a width of 1.4 meters, which broke the monopoly of Japan and the United States for 30 years. Long-term perfluorinated membrane preparation technology. The project obtained 14 patents during the research process, including 12 invention patents. The self-developed ion membrane was successfully applied industrially on the 10,000-ton chlor-alkali equipment at the end of June this year, making China the third largest company in the world to have chloralkali ions. Film core technology and production capacity of the country.

As a major producer and consumer of fluorosilicone materials, during the “11th Five-Year Plan” period, China has not only developed into a major producer and exporter of primary fluorochemical products, but also achieved breakthroughs in fluorochemical deep processing products such as PTFE. The production of hydrofluoric acid has increased from 0.3 million tons in 2004 to 1.3 million tons in 2009, and the production capacity of PTFE has reached more than 50,000 tons in 2009; large quantities of important fluorides such as hydrogen fluoride, aluminum fluoride and cryolite have been produced. The company has already owned 10,000 tons and more tons of production equipment with international advanced level; it has mastered the design and manufacturing technology of large-scale hydrogen fluoride complete sets of equipment, and the key equipment has achieved localization; the new process technology of fluorine gas internal circulation to prepare fluorinated graphite has reached the international advanced level. Level. In 2007, Xinghuo Silicone Plant built China's first Methyl Chlorosilane monomer plant with an annual production capacity of 100,000 tons. Xinan Chemical, Jiangsu Melan and other companies' silicone monomer units have also been put into production. In 2009, China's organic silicon monomer capacity reached 980,000 tons, making it the world's largest producer of organic silicon monomers.

In the field of synthetic rubber, Sinopec Group has developed a polymerization-grade isobutylene production technology through technological breakthroughs and formed a 10,000-ton-grade butyl rubber production capacity, which fills the shortage of domestic butyl rubber production gaps and makes all seven of China's general-purpose synthetic rubber types. Realized localization. Shandong Qilu Petrochemical Engineering Co., Ltd. built the first domestic 100,000 tons/year milk polybutadiene-butadiene rubber (SBR) unit that uses domestic technology. The monomer conversion rate is 70%, reaching the world's advanced level. Beijing University of Chemical Technology and the Daun Group are aiming at the future development of the automotive industry and have jointly developed a fully pre-dispersed-dynamic* process for the preparation of TPV industrialized technologies. The product has been widely used in Honda, BYD and other models, making contributions to the localization of automotive materials.

During the "Eleventh Five-Year Plan" period, China's rubber industry is also worth noting in the development of engineering radial tire production technology. The giant engineering radial tire production technology and equipment development project completed by Triangle Group Co., Ltd. won the 2007 National Science and Technology Progress Award, which is the highest technology award ever won by the Chinese tire industry since the founding of the People's Republic of China. The Triangle Group has spent five years tackling key issues and has overcome a series of technical problems by creating product designs, structural designs, formula designs, and process designs, ending the history that China cannot produce giant radial tires. This project broke the international **, won 4 national invention patents and 16 software copyrights, and is a major technological innovation in the tire industry.
