Abstract

The invention relates to a chemical technology field, concretely, discloses high-hardness white unsaturated polyester priming paint and a preparation method thereof. The priming paint contains a first component, cobalt isocaprylate (blue wate), methylethyl ketone peroxide (white water), and a diluent, wherein the weight ratio of the first component, to cobalt isocaprylate (blue wate), to methylethyl ketone peroxide (white water) and to diluent 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 has bad hardness, the usage of unsaturated polyester paint reduces the VOC content of the paint, and the high-hardness white unsaturated polyester priming paint has good fullness and filling 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 white primer and a preparation method thereof. Background technique [0002] Wood coating refers to the coating used on equipment made of MDF, solid wood board, veneer, etc., including furniture, floors, stationery, musical instruments and architectural decoration materials. It can be roughly divided into two categories. One is used for furniture. Manufacturing plants, one type is used for interior decoration and decoration; at present, the competition of furniture manufacturing plants is becoming more and more fierce, and most of the furniture manufacturing plants need to reduce the cost urgently, and the cost of paint decoration is one of the ways for furniture factories to reduce the cost of furniture products At present, most furniture manufacturers use PU polyurethane coatings, nitrocellulose coati...
