Innovation and development of new chemical material industry in China

New chemical materials have become more and more important in the world due to their lighter weight, better performance and stronger functionality, especially higher technical requirements and technical content; new chemical materials and their modified materials or composite materials have always been an important embodiment of a country's chemical technology level, plus the more excellent characteristics that traditional chemical materials and metal materials do not have As an indispensable supporting material for high-end manufacturing industry, it is also the first choice for key development and strategic transformation of developed countries and multinational companies. New chemical materials usually refer to engineering plastics, special engineering plastics, high-performance fibers, functional membrane materials, and sometimes polyurethane materials, fluorosilicone materials, high-end polyolefins and electronic chemicals. Five engineering plastics: Polyamide, paraformaldehyde, polycarbonate, PBT, polyphenylene ether; five special engineering plastics: polyphenylene sulfide, polyimide, polysulfone, polyethersulfone, polyetherketone. With the progress of technology and continuous innovation, especially the types of special engineering plastics have been expanded in recent years, and their varieties and properties have been continuously enhanced.

The development of lightweight vehicles, especially new energy vehicles and driverless technology, the large-scale civil airliner, such as A380, dreamlike 787 and our c929, etc.; as well as electronic information, human space exploration and spacewalk, stealth technology of national defense and military industry, aircraft carrier submarine and other deep-sea ocean ocean, all cannot be separated from new chemical materials. Developed countries such as the United States, Europe, Japan and the top 50 multinational companies in the global chemical industry all focus on the development of new chemical materials. Many well-known multinational companies take new chemical materials as the first choice for transformation, while increasing innovation in the field of new chemical materials, while speeding up the high performance of traditional chemical materials. In recent decades, they have basically completed the transformation from traditional chemical industry to new chemical materials Domain transformation. The typical example is the development of Dow DuPont, as well as the merger and re split in recent years. The new Dow split on April 1 this year is positioned as a new material business with an annual sales volume of about 48 billion US dollars. Since DuPont was founded in 217 years, it has realized the transformation from a chemical company to a material science in the 20th century. The new DuPont split on June 1 is positioned as a special chemical The leading products also belong to the field of new materials as we call it, with an annual sales volume of about 25 billion US dollars. The focus of Mitsubishi Chemical is also on the development of new chemical materials. Functional materials include high-function films, engineering plastics, carbon fiber and its composite materials, Lithium-ion battery materials, etc.

The core business of Mitsui chemical is also functional materials. Its metallocene polymerized LLDPE, HDPE and polyurethane materials are at the leading level in the world. Mitsui chemical also focuses on the field of new materials in the future. Multinational companies have positioned their development in China in the field of new materials. Mitsubishi, Mitsui, xuhuacheng, akoma, Longsheng and other companies continue to build and put into production new material projects in China. The typical case is that BASF and ExxonMobil announced to invest 10 billion US dollars to build new material bases in Zhanjiang and Daya Bay respectively. As a large manufacturing country, China has a large market demand for new chemical materials. However, the output and types of new chemical materials in China are difficult to meet the actual demand of domestic high-end manufacturing industry, which has always been a short board and weak point in the field of chemical industry. According to the research results of the Ministry of industry and information technology on more than 130 key basic materials in China, 32% of them are blank in China, and 52% of them are imported. Some materials are monopolized by some companies because of the technical bottleneck, such as Dongli and Dili, which monopolize the market of high-performance fiber and composite materials, DuPont and Dili control 90% of the production capacity of aramid fiber, and Xinyue, wake, Sumitomo and Mitsubishi occupy 80% of the international market of semiconductor silicon materials.

According to the statistics of the special committee for new materials, the output of new chemical materials in China in 2018 is about 22.1 million tons, with a self-sufficiency rate of about 65%; among them, the output of engineering plastics is 3.06 million tons, with a consumption of 5.48 million tons, with a self-sufficiency rate of about 55.9%; the output of functional membrane materials is about 5 billion square meters, with a consumption of more than 6 billion square meters, with a self-sufficiency rate of over 80%; the consumption of electronic chemicals last year was about 900000 tons, with a low share of domestic products, such as photoresist The import dependence of some products such as polymer packaging materials is over 80%, especially the high-end products are almost all imported. It can be said that since the new China, the new chemical materials have been the key development area of national economy. At the beginning, the new chemical materials are mainly used for supporting national defense and military industry. In the period of aging Ministry of work, there are two bureaus, which are specially responsible for the research and development of new chemical materials and production supporting. After the reform and opening up, with the electronic information, automobile manufacturing With the development of aerospace and other high-end manufacturing industries, the five-year development plan and annual plan of each chemical industry focus on new chemical materials. Many kinds of engineering plastics and special engineering plastics, as well as technical breakthroughs, large-scale production and large-scale promotion of fluorosilicone materials, polyurethane materials, aramid and carbon fiber materials, membrane materials, etc. are all in these processes Achieved. Entering many "third tier" enterprises, we can realize that the chemical new material industry is also a miniature of our country's independence and self-reliance.
