Yin Dulin: new chemical materials to surpass

New chemical materials are the most dynamic and potential industries in modern materials industry. They are basic materials, polymer materials and composite materials manufactured through molecular design and advanced chemical processes, involving synthetic rubber, engineering plastics, high-performance fibers, fluorosilicone materials, degradable materials, functional membrane materials, functional polymer materials and composite materials The transformation and upgrading of traditional industries have important applications in the fields of aerospace, marine equipment and other cutting-edge technologies, and play an important role in the development of strategic emerging industries. The new chemical material industry chain is an industry cluster of "basic chemical materials - structural and functional materials - composite (matching) materials - high-end chemicals and services". Hunan chemical new material industry chain provides material support for the continuous growth and innovative development of Hunan rail transit, advanced manufacturing, information technology, automobile industry, aerospace, biomedicine, new energy, energy conservation and environmental protection and other emerging advantageous industries. Its demand is on the rise.

What are the advantages of developing new chemical materials in Hunan? How will new chemical materials promote the transformation and upgrading of new material industry and structural adjustment, and enhance the core competitiveness of new material industry? Recently, red net interviewed Yin Dulin, Dean of the school of chemistry and chemical engineering of Hunan Normal University. "Industrial transformation and upgrading and structural adjustment must be driven by market or social demand. The 'new' vitality of new chemical materials is new quality and new varieties, that is, around the development of new material industry chain, key equipment and major projects, to continuously improve or adjust the quality of new chemical materials and create new chemical materials varieties, in order to enhance the core competitiveness of new material industry. " Yin believes that in the development of new chemical materials industry, we should not narrow down to polymer materials and other fields, but pay more attention to the coordinated development of basic raw materials. For example, the high-quality epoxy resin is a problem that perplexes the development of chip industry in China. The basic reason lies in the low resistance of the resin.

In the final analysis, it is caused by the conductive impurities in a series of domestic special phenols. In recent years, the industrialization of methylation o-cresol, such as Hunan Changling Kekai company, has overcome this problem. Therefore, the development of new chemical materials must be placed in the "basic chemical materials - structural and functional materials - composite (matching) materials - high-end chemicals and services" industrial chain cluster collaborative innovation. At present, there are some differences between the development and application of new chemical materials at home and abroad. Yin Dulin said that due to the lag in the development of modern industrial civilization, compared with developed countries such as Europe, the United States and Japan, the domestic chemical industry has been running for a long time, taking breaking through the neck products as the innovation breakthrough, and the development of new chemical materials is mostly to fill the domestic gap in varieties or International advancement in quality is achievement. "At the 70th International Astronautical Congress in Washington recently, the cruel fact that Chinese Representatives failed to obtain visas to enter the United States reminded us that the R & D and application of new chemical materials in China should continue to be based on the national strategy and the development needs of the national economy and people's livelihood, discover and drive Chinese invention, Chinese manufacturing and Chinese engineering with China, and promote the cultivation of innovative talents at different levels through the integration of science and education, The integration of industry and education promotes the close combination of basic research and technology integration, commercializes the samples, applies the discovery of principles to strengthen the molecular design, molecular synthesis, function mining, engineering development, green manufacturing and cleaner production of new chemical materials, improves the utilization rate of resources, improves the utilization value of resources, and strives for the breakthrough and accumulation of winning the Nobel Prize in chemistry as the Chinese nation One of the contributions of the development of new chemical materials in the world and the mark of catching up. "Hunan is an important strategic base of chemical basic materials and functional materials in China.

As early as the early 1950s, the country has laid out industries such as coal chemical industry, salt chemical industry and phosgene products in Hunan; at the end of the 1960s, the petrochemical industry base was established in Yueyang, laying the foundation of Hunan's new chemical material industry. Hunan's new chemical material industry has grown with the development of the petrochemical industry in the province. According to the data provided by the Provincial Bureau of statistics, in 2017, there were 1497 Enterprises above the scale of petroleum and chemical industry in the province, with 225000 employees and 263 billion yuan of main business income, up 11% year-on-year. Among them, the output value of new products was 39.810 billion yuan, down 16.1% year-on-year; the export delivery value was 5.771 billion yuan, up 24% year-on-year .8%. The industrial added value reached 68.507 billion yuan, an increase of 2.2% on a year-on-year basis; the assets of the whole industry totaled 138.404 billion yuan, an increase of 12.5% on a year-on-year basis. The total profit of the whole industry was 11.335 billion yuan, up 53.5% year on year; the total profit and tax was 28.949 billion yuan, up 6.7% year on year. Among them, the output value of new chemical materials in 2017 is 79.97 billion yuan, and the annual output value in 2018 is estimated to be about 90 billion yuan.
