Abstract

The invention belongs to the field of functional powder coating, and particularly relates to powder coating with a metal flashing effect, as well as a preparation method and an application method of the powder coating. The powder coating is prepared by combining a composition A, a composition B and a composition C, wherein the composition A comprises the following raw materials in percentage by weight: 26.0-35.0% of bisphenol A-type ethoxyline resin, 32.5-42.0% of carboxyl terminated polyester resin, 0.5-1.0% of a leveling agent, 0.3-0.6% of a degassing agent, 2.0-33.5% of one or more pigments and 10-20.0% of a filler; the composition B comprises the following raw materials in percentage by weight: 90-99% of the composition A and 1-10% of one or more metal pigments; the composition C comprises the following raw materials in percentage by weight: 77.3-80.3% of GMA-type acrylic resin, 18.2-21.2% of dodecanedioic acid, 0.5-1% of the leveling agent and 0.3-0.6% of the degassing agent. A double-layer coating film is formed after application of the powder coating, so that the powder coating is high in impact resistance and bending resistance. The invention further provides the preparation method and the application method of the powder coating.

Description

technical field [0001] The invention belongs to the field of functional powder coatings, and in particular relates to a metallic glitter effect powder coating, a preparation method and an application method thereof. Background technique [0002] Metal glitter effect powder coating presents a multi-color effect metallic color due to the use of flake pigments such as copper powder, aluminum powder, and mica powder. exterior decoration. The use of flake pigments also brings the defect of poor rub resistance. The crux of the problem is that the flake pigments floating on the surface of the coating film to provide a metallic glitter effect are damaged by friction and the environment is eroded, and the coating film is prone to blackening. Phenomenon. For this reason, it is usually necessary to coat the surface with a transparent coating for protection. The usual practice is to coat a layer of transparent powder after the metal glitter effect coating is cured, and then cure agai...
