Abstract

The invention relates to a chemical technology field, concretely, discloses high-hardness unsaturated polyester full-bright top-coat paint and a preparation method thereof. The priming paint contains a first component, cobalt isocaprylate (blue wate), methylethyl ketone peroxide (white water), and styrene, wherein the weight ratio of the first component, to cobalt isocaprylate (blue wate), to methylethyl ketone peroxide (white water) and to styrene is 100:(0.8-2):(1-2.5):(30-40). The high-hardness white unsaturated polyester priming paint and the preparation method resolve the problem that the PU polyurethane paint and nitro cellulose paint have bad hardness, the unsaturated polyester coating has high hardness, and simultaneously, the high-hardness unsaturated polyester full-bright top-coat paint has good fullness, clunging and minute surface effect.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, more specifically, the invention relates to a high-hardness unsaturated polyester all-bright clear topcoat and a preparation method thereof. Background technique [0002] At present, PU polyurethane coating and nitrocellulose coating have high VOC content, low hardness, and poor fullness. It is becoming more and more demanding, and the PU polyurethane coatings and nitrocellulose coatings that are currently used in large quantities require multiple sprays to achieve the fullness of the customer during the construction of the furniture factory. The furniture factory needs multiple sprays to achieve the required effect. As a result, the cost of furniture increases in disguise, and the content of solvent (VOC) is high. People have higher and higher requirements for environmental protection. Reducing volatile organic compounds (VOC) in coatings and improving the solid content of coatings ...
