Tough fusion-bonded epoxy powder coating



The invention discloses a tough fusion-bonded epoxy powder coating. The coating comprises the following raw materials by weight: 40 to 50 parts of a linear phenolic epoxy resin, 10 to 20 parts of an E-12 epoxy resin, 4 to 6 parts of calcium phosphate, 1 to 2 parts of phthalic anhydride, 2 to 4 parts of polyethylene wax powder, 2 to 3 parts of pentaerythritol, 2 to 3 parts of a long oil alkyd resin, 2 to 3 parts of polyisobutylene, 6 to 10 parts of diethylenetriamine, 1 to 2 parts of 4,4-methylene bis(cyclohexylamine) and 10 to 13 parts of a composite filling material. The epoxy powder coating provided by the invention is mainly used in the field of pipeline anticorrosion and has the advantages of good toughness and high shock resistance; and a preparation process for the epoxy powder coating is simple and applicable to scale production of the coating.
