Abstract

The invention provides nonylphenol-free epoxy paste paint, and solves the problems that epoxy paste paint used for a fishing rod or other sports goods contains harmful chemical substances such as nonylphenol and the color of the epoxy paste paint is easy to darken. Compared with the epoxy paste paint in the prior art, the nonylphenol-free epoxy paste paint provided by the invention does not contain a compound with a phenol structure, so that an obtained epoxy curing agent and a curing coating layer are relatively high in color stability and difficult to discolor; moreover, harms of nonylphenol to a human body and an environment are eliminated from the source; the nonylphenol-free epoxy paste paint meets the national environmental protection requirement and the environmental protection requirement for exporting the products to all districts in foreign countries, and is more ecological and environmentally-friendly.

Description

technical field [0001] The invention relates to an epoxy impregnated paint, which does not contain harmful compounds such as nonylphenol, and satisfies domestic and export requirements to countries and regions such as the United States and Europe. Background technique [0002] Epoxy thick paint is used for the coating, protection and decoration of fishing rod guide ring winding, fishing rod stickers and other places in the fishing gear industry. In current use, it is required that the thick epoxy paint after compounding has stable color, fast hardening at room temperature, high surface gloss, high flexibility and good chemical resistance. [0003] Existing thick epoxy paints meet the requirements of fast hardening and bright coating surface at room temperature, but as time goes by, photochemical reactions tend to generate colored groups, resulting in discoloration and affecting the appearance, especially for decorative purposes. The stickers are beautiful. [0004] In addi...
