Abstract

The invention discloses modified fluorine-containing resin coating and preparation and use method thereof, and belongs to the technical field of coating. The modified fluorine-containing resin coatingcomprises the following raw materials in parts by weight: 50-200 parts of modified fluorine-containing resin, 1-5 parts of a polyamide wax micro powder, 0.1-1 part of attapulgite, 0.5-10 parts of nano titanium dioxide and 0.5-10 parts of nano-silica, wherein the modified fluorine-containing resin comprises modified polytetrafluoroethylene (PTFE), a modified polyethylene-tetrafluoroethylene copolymer (ETFE or F40) and modified polyvinylidene fluoride (PVDF). The coating prepared by using the method disclosed by the invention has super-hydrophobic, anti-corrosion and anti-radiation functions, is simple in preparation process, and is green and free of pollution.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a modified fluorine-containing resin coating and a preparation and application method thereof. Background technique [0002] Environmental protection and energy conservation are two major themes of development in the world today. With the enhancement of people's awareness of environmental protection and the establishment of environmental protection laws and regulations in various countries, the emission of volatile organic compounds (VOC) is increasingly restricted, which promotes the development of the coating industry in the direction of environmentally friendly coatings. In addition to the superior weather resistance, chemical corrosion resistance and stain resistance of traditional fluorine coatings, water-based fluorine-containing coatings also have the advantages of safety and environmental protection, which are in line with the development trend of coatings and have attra...
