Abstract

The invention relates to the technical field of an epoxy resin powder coating, and more specifically relates to a strong-weatherability epoxy resin powder coating and a preparation method thereof. Thestrong-weatherability epoxy resin powder coating is prepared by epoxy resin, a curing agent, hydroxyl silicone oil, a silane coupling agent, salicylic acid, an acetone aqueous solution, polyvinylidene fluoride, polyvinyl fluoride or polytetrafluoroethylene, an ABS resin monomer composition, an initiator, water, an inorganic mineral filler, a levelling agent and an UV absorbent. The epoxy resin ismixed with hydroxyl silicone oil and the silane coupling agent to form organosilicon modified epoxy resin, the organosilicon modified epoxy resin is mixed with a mixture of polyvinylidene fluoride, polyvinyl fluoride or polytetrafluoroethylene, and the ABS resin monomer composition, and extrusion moulding is carried out to obtain the epoxy resin powder coating, the epoxy resin participates in anorganic silicone resin system, the material and the ABS resin composition form a high-molecular polymerization structure through polyvinylidene fluoride for further modification, and the strong-weatherability epoxy resin powder coating has the advantages of damp heat resistance, corrosion resistance, strong weatherability, good mechanical property, convenient preparation, concise process, and safety and non toxicity.

Description

technical field [0001] The invention relates to the technical field of epoxy resin powder coatings, in particular to an epoxy resin powder coating with strong weather resistance and a preparation method thereof. Background technique [0002] Powder coating refers to 100% solid powder coating without solvent, which exists in the state of fine powder, and is mainly composed of film-forming resin, additives, pigments, fillers, etc., mixed, crushed, and sieved. It needs electrostatic spraying and baking to form a film. It has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. Powder coatings include two categories: thermoplastic powder coatings and thermosetting powder coatings, of which thermoplastic powder coatings include polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide and cellulose, etc., ...
