At the Shandong Epoxy Resin Curing Agent Industry Development Forum, attention was paid to the development direction and modification technology of the key supporting industry curing agent for modified epoxy curing agent, which prompted the modified epoxy curing agent industry to accelerate the coordinated development and solve the domestic modified epoxy curing The situation of leading production capacity and insufficient demand in the pharmaceutical industry has become the focus of the participants. The experts at the meeting dug deeply from the application field of modified epoxy curing agent and listed four development directions of curing agent.
First, functional curing agent: As the development of a new structure and modified epoxy curing agent with excellent performance has not made much progress, so as to meet the resin modification requirements, curing agents with special functions will become the market darling. Compared with traditional curing agents, functional curing agents usually have excellent properties such as fast curing, low temperature curing, toughening, and flame retardant.
Second is a low-toxic and non-toxic curing agent. At present, the industry not only pays attention to the problem of toxicity and environmental pollution in the production and use of curing agents, but also pays attention to the long-term pollution of waste modified epoxy resin curing agent products.
Third, electron beam and light-curable products have attracted more and more attention.
Fourth, powder coating, water-based modified epoxy curing agent coating special curing agent and one-component adhesive curing agent have broad prospects.
For these four development directions of curing agents, specific modification technologies matching them are proposed, such as: fatty amine modification, modified epoxy curing agent scent amine modification (especially m-phenylenediamine, m-phenylenedi Methylamine modification), acid compound modification and liquidization, dicyandiamide modification and liquidization, imidazole modification and liquidization, etc. It is imminent to accelerate the coordinated development of the modified epoxy curing agent industry. On the premise of complying with environmental protection and safety regulations and satisfying the needs of users, the cost is continuously reduced. The development of serialization, specialization, matching and refinement is the long-term task of the curing agent manufacturer. .
Experts suggest that in order to accelerate the coordinated and healthy development of the modified epoxy resin curing agent industry in Shandong, the modified epoxy curing agent and curing agent production plants should form partnerships and promote each other. This is an effective way for the entire industry to succeed. Polyamide is a product of polycondensation reaction between fatty amine and dimer acid, fatty acid, etc. It contains groups such as amido, amine and imidazoline ring. Polyamides are further modified into polyamide adducts by addition of liquid or modified epoxy curing agents, which can improve their viscosity and performance, and are usually provided in the form of solvents or diluents dissolved into solutions.
