Abstract

The invention discloses a poaching-resistant powder coating composition. The poaching-resistant powder coating composition at least comprises thermosetting resin, a curing agent for crosslinking and curing of the thermosetting resin, and pigments and fillers, wherein the pigments and fillers comprise aluminum hydroxide and a hydrophobic coated pigment. According to the invention, the aluminum hydroxide filler and the hydrophobic coated pigment have a synergistic effect in a cured coating film; the raw materials have excellent hydrophobicity; and meanwhile, the compactness of a coating film can be remarkably improved, water vapor can be effectively prevented from penetrating through the coating, and the poaching resistance of the coating film is effectively improved.

Description

technical field [0001] The invention belongs to the field of powder coatings, in particular to a boiling-resistant powder coating composition. Background technique [0002] Thermosetting powder coatings are widely used to replace paints and water-based paints to achieve protective decoration for products in various fields due to their advantages of environmental protection, low energy consumption, convenient construction and no VOC emissions. However, when it is applied to some specific product fields, there are usually special requirements for its water boiling resistance, which cannot be achieved by conventional powder coating products. [0003] Therefore, the applicant wishes to seek a new technical solution to improve the boiling resistance of powder coatings. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a kind of boil-resistant powder coating composition, aluminum hydroxide filler and hydrophobic coating type ...
