Although China's epoxy resin industry is subject to macroeconomic regulation and control, especially the impact of the scale of investment in the construction industry, the demand has declined to varying degrees, but it still maintains a growth rate of around 20%, and the annual consumption will reach 600,000 tons, becoming a The world's largest consumer of epoxy resin. Experts predict that at the end of the “Eleventh Five-Year Plan” period, China’s epoxy resin consumption will increase by a factor of two to reach 1.2 million tons.
Epoxy resins have a large number of applications, and they have been developed from indoor applications to outdoor and even space space. The traditional bisphenol A epoxy resin has not been able to meet the needs of applications. As a big producer of epoxy resin, China has also been at the forefront of the world in variety innovation. New varieties emerged in an endless stream. Alicyclic epoxy resins, hydrogenated bisphenol A epoxy resins, bisphenol F epoxy resins, and glycidol have been developed. Amino-ether type epoxy resin, bisphenol A novolac epoxy resin and a large number of high-tech new products. Leading enterprises Bluestar new materials Aerospace products produced by the Wuxi Resin Plant are used in China's previous space launches, including the 'God Five' and 'Shen Six' manned launches. At the same time as the level of technology has increased, the scale of production has also expanded significantly, resulting in a significant drop in product consumption, sewage discharge, and production costs. According to experts from the China Epoxy Resin Industry Association, the current competitive capacity of bisphenol A epoxy resin production equipment with an annual output of 20,000 tons or less has been very limited, and the industry has basically no longer considered new construction. Bluestar New Materials Wuxi Resin Factory and Hong Kong Jianye Group Company are currently building 40,000 to 50,000-ton devices. In the previously unattractive epoxy resin industry group in Huangshan, a batch of 10,000-ton grades such as Hengyuan also emerged. manufacturer.
Curing agents are indispensable materials in the application of epoxy resins, and are also the bottleneck for the development of the epoxy resin industry. Because curing agents are much more diverse than epoxy resins, many applications of epoxy resins require curing agents that are technically more difficult than epoxy resins. This is also the rapid development of China's epoxy resin, and the reasons for the application of high-tech products to people. According to experts from the China Epoxy Resin Industry Association, China's anhydrides, resins, dicyandiamides, polyamides, and modified amine curing agents have all been able to produce, but there is still a certain gap in quality and variety. If this phenomenon does not change, the future will affect China's epoxy resin industry itself. At present, the domestic industry has attracted enough attention and achieved certain results. For example, Jiangxi Yichun Yuanda Chemical Co., Ltd. is a professional dimer acid and polyamide resin supplier. Its dimer acid production capacity has reached 10,000 tons/year. Has exceeded Japan, and has been sold to Singapore, China Taiwan, India, South Korea and other places; Wenzhou Qingming Chemical Co., Ltd. anhydride curing agent has also entered the European market, indicating that China's anhydride curing agent has a certain degree of international competitiveness; The development of a new type of curing agent from Changsha, Huayan, Dongfang Huayin, Xi'an Taihang, Northwest Engineering University and China Academy of Forestry is also exciting. However, our country's basic amine curing agent has almost no place of production. Although there are many modified amine production plants, it is faced with the difficult situation of high-priced raw materials. Experts called for further expansion of the production capacity of alicyclic amines and m-xylylenediamine, and accelerated the development of basic amines such as ethylenediamine and diethylenetriamine to keep pace with the rapid development of China's epoxy resins.
China's epoxy resin industry is moving towards systematization, that is, the research and cooperation of epoxy resin, ancillary products, and application technologies in the same system, which has changed the situation in which individual departments were separated from each other in the past, which is conducive to forming a joint force and strengthening the industrial chain effect. . This trend has been clearly seen in several exhibitions since last year. Its general feature is the wide range of applications for communication technology, from coatings to adhesives, from castables to composites, from resin modification to curing. The compounding of agents, from the selection of reactive diluents to the consideration of filler particle size distribution, from the construction equipment to the test equipment, from the design of the formulation to the specific use, fully reflects the epoxy resin system in the epoxy industry in China. The research is more and more in-depth, which will play a guiding role in the development of China's epoxy resin application market, and will also promote the wider application of epoxy resin in China.
