China Chemical Industry, June 12, 2024. According to reports from Sinochem News, the project undertaken by Henan Leibairei New Materials Technology Co., Ltd. as part of Puyang City’s major scientific and technological initiatives in 2022, namely the research on producing methylcyclohexylamine – a curing agent used in wind turbine blades – has passed expert evaluation. 　　According to the relevant officials at Leibairei, methylcyclohexylenediamine is produced by the hydrogenation of tolylenediamine in the presence of a catalyst. It is a type of alicyclic amine curing agent that offers advantages such as low viscosity, a long curing time, good corrosion resistance, and high temperature tolerance. It is an essential curing agent material among the basic raw materials used in the manufacture of wind turbine blades. 　　In 2022, Leibaire actively took on major scientific and technological projects at the Puyang city level, focusing on research and development of core technologies related to methylcyclohexanediamine, and ultimately achieved domestic production of this substance. At present, the methyl cyclohexanediamine produced by Leibairei can replace imported curing agent products, and cooperation agreements have been signed with 16 enterprises including Aipuko Aviation Technology (Taizhou) Co., Ltd., resulting in an output value of 41.99 million yuan. Methylcyclohexanediamine (HTDA) is produced by the hydrogenation of toluenediamine in the presence of a catalyst; it is a alicyclic amine curing agent that offers advantages such as low viscosity, a long curing time, good corrosion resistance, and excellent temperature tolerance. This product can be used as a curing agent on its own, or it can be mixed with other conventional epoxy curing agents (such as aliphatic amines, alicyclic amines, aromatic amines, anhydrides, etc.) or general accelerators (such as tertiary amines, imidazoles). It enables the curing of epoxy resins over a wide temperature range, and is widely used in various fields that require epoxy curing agents, including composites, coatings, wind turbine blade materials, and adhesives. Meanwhile, the isocyanate synthesized from it is an alicyclic isocyanate, which, when used in combination with aliphatic or alicyclic diamines, polyether amines, etc., exhibits excellent resistance to yellowing under light and air exposure. It can be used to produce special polyurethane materials, and serves as an important intermediate in organic and fine chemical industries, offering broad prospects for market application. 　　Henan Leibairei New Materials Technology Co., Ltd. was established in 2015; it was founded by enterprises that originated from Zhongyuan Petrochemical. The company is dedicated to the development, production, and promotion of the market use of domestic curing agents based on high-end specialty amines. The products (DETDA and HTDA) are primarily used in industries such as polyurethane elastomers, polyureas, and epoxy resins, and their quality is on par with that of companies such as Albemarle in the United States, Lonza in Switzerland, and BASF in Germany. The company has been recognized with various honors, including **-level high-tech enterprise, a \"specialized, refined, distinctive and innovative\" small and medium-sized enterprise in Henan Province, a technology-based small and medium-sized enterprise, an enterprise designated for the development of intellectual property strengths in Puyang City, the Key Laboratory for Special Amine Series Chain Extenders in Puyang City, and the Engineering Technology Research Center for Special Amine Series Curing Agents in Puyang City. 　　The Henan Leibairei New Energy Materials Industrial Park is expected to require an investment of 1.28 billion yuan. Planned and constructed in two phases. Phase 1 will focus on the development of special amine product lines, while Phase 2 will address the production of high-value-added polyolefins. This project makes use of the excess ethylene, propylene, and butylene available in the Zhongyuan area, as well as the excess hydrogen produced by Zhongyuan Dahuahua, to produce high-end amine curing agents. It aims to fill the gap in China’s supply of such high-end curing agents, break foreign monopolies, and support the rapid development of China’s industries related to new energy materials, polyurethanes, and epoxy resins.
