Abstract

The invention discloses an oil-repellent thermosetting powder coating and a preparation method and application thereof. The powder coating consists of the following raw materials in part by weight: 20 to 90 parts of acrylic resin, 5 to 20 parts of organic silicon resin, 4 to 50 parts of curing agent, 0.1 to 1.5 parts of flatting agent, 0.2 to 0.8 part of degassing agent, 5 to 45 parts of pigment filler, 0 to 20 parts of thermosetting fluorocarbon resin, 0 to 50 parts of hydroxyl polyester resin and 0 to 2 parts of other aids. The provided oil-repellent thermosetting powder coating has the advantages of scientific and reasonable ratio of components of each raw material and raw materials, and synergy of the components. A high-density film can be formed on the surface of a coating film sprayed by the provided powder coating, the polarity which repels oil dirt can be formed on the surface of the coating film, oil substances cannot attach to the surface of the coating film for a long time, and the oil dirt is easily removed. The coating film has the advantages of excellent oil repellency, economical efficiency, environmental protection and wide use.

Description

technical field [0001] The invention relates to a powder coating, in particular to an oil-repellent thermosetting powder coating, a preparation method thereof and its application in preparing an oil-repellent self-cleaning decorative coating. Background technique [0002] In the past ten years, with the rapid development of my country's economy, the demand for high-grade decorative powder coatings is also increasing year by year. Recently, the market demand for oil-repellent coatings is getting higher and higher, such as in kitchens and some public squares, bus stops, etc. Occasionally, oily marker pens or other ink pens are often used for imprinting, small advertisements, etc., which seriously pollute the environment and affect the appearance of the city. Therefore, a paint that is oil-repellent and easy to clean is needed. Water-based and other paints are currently on the market. Liquid coatings already have some similar products, but they still cannot meet the needs of the ...
