Abstract

The invention belongs to the technical field of coating preparation, and particularly relates to a modified polyester extinction powder coating and a preparation method thereof. The modified polyesterextinction powder coating comprises, by weight, 50-60% of solid modified polyester resin, 4-4.5% of curing agent triglycidyl isocyanurate, 5-10% of solid pigment, 2-3% of a solid additive and 25-35%of a solid filler, wherein the solid modified polyester resin is obtained by modifying polyester resin with dimethyl adipate, the solid filler comprises precipitated barium sulfate, 1500-mesh barium sulfate, 2000-mesh calcium carbonate and 800-mesh calcium carbonate, and the product is low in glossiness, capable of providing glossiness as low as 10%, good in storage stability, high in impact resistance and good in adhesive force and has good leveling and stable physical properties.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a modified polyester matting powder paint and a preparation method. Background technique [0002] At present, powder coatings are widely used outdoors, and the varieties are also increasing. Generally speaking, noble and luxurious decorations require high gloss, while quiet, comfortable and elegant environments require low gloss. However, high-gloss coatings will produce serious light pollution and cause damage to the eyes. In addition, consumers' aesthetic concepts are also changing, and they are more inclined to a leisure and comfortable living environment. Therefore, matting powder coatings that can produce soft surface effects are more and more widely used. According to statistics, the consumption of semi-gloss and matt powder coatings has exceeded 30% of the total powder coatings for indoor and outdoor use. Contents of the invention [0003] The tec...
