Abstract

A curing agent for powdered paint of polyester resin relates to the production technique field of powdered paint of polyester resin. The novel curing agent consists of tetra adipamide (2-hydroxyethyl group) and tris isocyanurate (2-hydroxyethyl group); wherein, the tetra adipamide (2-hydroxyethyl group) accounts for 50 to 90 percent of the gross weight and the tris isocyanurate (2-hydroxyethyl group) accounts for 10 to 50 percent of the gross weight. The invention not only has tetra adipamide (2-hydroxyethyl group) with the advantage of Beta-hydroxyl alkyl amide, but also has the widely-used tris chlorinated Isocyanurates (2-hydroxyethyl group) with the advantages of safety and low toxicity. Simultaneously, the tris chlorinated Isocyanurates (2-hydroxyethyl group) and the tetra adipamide (2-hydroxyethyl group) have similar structure of (2-hydroxyethyl group) active functional group, thus having similarities and compatibility.

Description

technical field [0001] The invention relates to the technical field of polyester resin powder coating production. Background technique [0002] There are two main types of current polyester resin powder coating curing agents, one is triglycidyl isocyanurate (TGIC), and the other is four (2-hydroxyethyl) adipamide as the main representative. β-Hydroxyalkylamides (HAA). [0003] The toxicity of triglycidyl isocyanurate (TGIC) has been controversial, and it has a certain impact on the environment and human health. Therefore, many countries and regions in the world have already begun to resist its application, especially in Europe. . TGIC's research work on substitutes has been carried out all over the world. [0004] The PRIMID XL-552 produced by the foreign EMS-CHEMIE Swiss company is a β-hydroxyalkylamide (HAA), and its chemical composition is tetrakis (2-hydroxyethyl) adipamide, which has been used as a curing agent for polyester resin powder coatings. It is widely used ...
