Problems solved by technology

Due to its excellent adhesion, corrosion resistance, hardness, flexibility and impact strength, epoxy resin is the first type of application in thermosetting powder coatings. It has been widely used in household appliances, vehicles, hardware machinery and other fields, but Due to the presence of aromatic ether groups in the epoxy resin coating, it is extremely sensitive to ultraviolet rays, so that its heat resistance is not high, and its aging resistance is not good. It is easy to yellow and chalk during baking or sunlight, which affects the gloss. In addition, as a polymer material, its flame retardancy is not very good. In the process of use, there are defects of poor flame retardancy, which limits its application.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a heat-resistant, corrosion-resistant and highly flame-retardant epoxy resin powder coating. Background technique [0002] Powder coating is a new type of solvent-free, 100% solid powder coating, which has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity, and high mechanical strength of the coating film. It is divided into thermoplastic powder Coatings and thermosetting powder coatings. Due to its excellent adhesion, corrosion resistance, hardness, flexibility and impact strength, epoxy resin is the first type of application in thermosetting powder coatings. It has been widely used in household appliances, vehicles, hardware machinery and other fields, but Due to the presence of aromatic ether groups in the epoxy resin coating, it is extremely sensitive to ultraviolet rays, so tha...
