Abstract

The invention discloses glossy unsaturated polyester finish paint. The glossy unsaturated polyester finish paint comprises components A, components B, a component C and a component D. The components A include 1:35-50% of modified unsaturated polyester resin, 2:25-40% of modified unsaturated polyester resin, 3:5-8% of unsaturated polyester resin, 0.3-0.5% of antifoaming agent, 0.3-0.7% of flatting agent, 6-12% of divinyl benzene, 5-12% of styrene, 0-0.05% of polymerization inhibitor, 2-4% of toluene and 2-4% of ethyl ester, and the proportions of the components A are 100% totally. The components B include 10-30% of styrene, 20-45% of ethyl ester, 10-30% of toluene, 15-25% of xylene, 10-20% of butyl ester and 1-5% of cyclohexanone, and the proportions of the components B are 100% totally. The component C includes a colorless accelerator. The component D includes whitewater. During construction, construction is conducted according to the weight proportion that the components A:the components B:the component C:the component D=100:15-25:0.5-2:1-3. The cracking resisting effect is good, edge breakage is avoided, the color of a paint film is light, the ground color can be highlighted on the light color bottom, definition is high, and the overall appearance quality of a product can be improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a bright unsaturated polyester topcoat. Background technique [0002] Under the current general environment, high-solid water-based coatings have become a trend. Unsaturated polyester coatings have gradually attracted people's attention due to their high solid content and excellent performance. Compared with conventional solvent-based polyurethane coatings, It has the advantages of high solid content in construction, good fullness, high hardness, strong resistance to collapse, and thick coating at one time. However, due to the high cross-linking density, the paint film of polyurethane coatings is relatively brittle, and it is easy to cause chipping when trimming and drilling furniture products. Moreover, the conventional oxidation-reduction system catalyzes the curing, and the final paint film color is purple to green, which affects the final appearance of wood products. Contents of th...
