Problems solved by technology

[0002] The matting of the traditional matt powder coating is to add matting curing agent during the powder production process, so that the powder can achieve matting effect during the curing process. The addition of this matting curing agent makes the low-temperature kneading process exist in the powder production process. As a result, impurities are formed before the powder solidifies, thus reducing the powder quality

Abstract

The invention discloses dry mixed matt powder paint, which comprises component A and component B. The component A comprises the following materials by weight portion: 25 to 28 portions of vibrin A; 2 to 5 portions of TGIC; 5 to 7 portions of BaSO4; 2 to 5 portions of CaCO3; and 1.5 to 2.5 portions of TiO2. The component B comprises the following materials by weight portion: 25 to 28 portions of vibrin B; 2 to 5 portions of TGIC; 4.5 to 6.5 portions of BaSO4; 2.5 to 4 portions of CaCO3; and 0.8 to 1.0 portion of TiO2. By comparing the invention with the prior art, the dry mixed matt powder paint contains little impurity, and has excellent scratch resistance and impact resistance as well as comfortable luster, which is solventless thermoset high strength decorative antifriction material and can eliminate light when the powder is cured.

Description

technical field [0001] The invention belongs to matte powder non-coating, in particular to dry-mixed matt powder non-coating. Background technique [0002] The matting of the traditional matt powder coating is to add matting curing agent during the powder production process, so that the powder can achieve matting effect during the curing process. The addition of this matting curing agent makes the low-temperature kneading process exist in the powder production process. As a result, impurities are formed before the powder solidifies, thus reducing the powder quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dry mixed matt powder coating with less impurities. [0004] The technical solution of the present invention to solve the technical problem is: dry mixed matt powder without coating, composed of component A and component B, [0005] Described component A comprises following material and parts by weig...
