Abstract

The invention relates to a formula of a metallic flashing lacquer capable of resisting machining and cutting, and a preparation method of the metallic flashing lacquer. The formula comprises the following components in parts by weight: 35-50 parts of high-solid-content linear polyester resin, 6-15 parts of butylated amino resin, 3-18 parts of blocked isocyanate, 1-3 parts of polyamide, 1-4 parts of cellulose acetate butyrate, 0.05-0.4 part of surface leveling aid, 4-8 parts of aluminum paste, 1-3 parts of adhesion promoter aid, 4-8 parts of dimethylbenzene, 4-8 parts of butanol, and 4-8 parts of n-butyl acetate. The metallic flashing lacquer is less in environmental pollution, and lower in VOC content, and has excellent flexibility, surface decoration effect and finish turning and machining resistance properties.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a metal flash paint resistant to machining and cutting and a preparation method thereof. Background technique [0002] In order to improve the market competitiveness and enhance the overall decoration of the vehicle, many mid- and high-end automobile manufacturers require the front of the aluminum wheels used to maintain the mirror effect, and the inside of the window to retain the sparkle and color of the metallic flash paint. The construction method is: the aluminum wheels of cars and SUVs are not sprayed with transparent paint after completing the pre-treatment of the aluminum base material, spraying the base powder and metallic paint, and directly put them into the oven. The paint is peeled off together with a layer of aluminum to expose the aluminum, and then the paint line is cleaned after cleaning, sprayed with transparent paint or transparent powder, and then ...
