Abstract

The invention discloses anti-cracking unsaturated polyester paint and a preparation method thereof. The anti-cracking unsaturated polyester paint is prepared from the following raw materials in partsby mass: 25 to 40 parts of unsaturated polyester resin, 5 to 10 parts of short oil modified alkyd resin, 0.1 to 1 part of dispersing agents, 0.1 to 1 part of anti-foaming agents, 0.1 to 1 part of leveling agents, 0.3 to 0.6 part of fused silicon oxide, 40 to 60 parts of pigments and fillers and 5 to 30 parts of solvents. The anti-cracking unsaturated polyester paint has the advantages that the product toughness is good; the internal stress release is fast; the problem of cracking at the later period can be greatly reduced to the maximum degree. Compared with the PE paint in the market, the paint has the advantages that the use tolerance is better; the anti-cracking unsaturated polyester paint is very suitable for being used as easy-shrinkage substrates suitable for Northeast China regionswith great diurnal temperature variation; for other performance, the smell is lower than that of other PE paint in the market; the grinding is easy; the plate surface effect is good; the fullness degree is high; the glossiness is higher; the comprehensive performance is excellent.

Description

technical field [0001] The invention relates to an unsaturated polyester paint, in particular to an anti-cracking unsaturated polyester paint, and also relates to a preparation method of the anti-cracking unsaturated polyester paint. Background technique [0002] In the mature furniture production industry, the degree of centralized production is becoming more and more obvious, and the efficiency of furniture production and shipment has become one of the required indicators pursued by many enterprises. The coating film made of unsaturated polyester resin furniture paint (referred to as "PE paint") can be thickly coated at one time, and it takes longer to use polyurethane paint (PU paint) or nitro (NC) paint and water-based, UV, etc. Short construction drying time and multiple spraying and polishing, one thick coating of PE paint improves production efficiency and greatly shortens the delivery cycle, so PE unsaturated polyester paint is widely favored by furniture companies. ...
