Abstract

The application relates to the technical field of coatings, and provides an unsaturated polyester primer and a preparation method thereof. The unsaturated polyester primer provided by the application includes the first component, and the first component includes: 41-48 parts of air-drying unsaturated polyester resin; 5-8 parts of thermoplastic acrylic resin; 0.1-8 parts of defoamer 0.3 part; dispersant 0.5‑1 part; leveling agent 0.2‑0.4 part; anti-settling agent 0.2‑0.3 part; colorant 8‑10 part; zinc stearate 4‑6 part; 0.1-0.3 parts of greening agent; 2.4-4.5 parts of thinner. By compounding thermoplastic acrylic resin with air-drying unsaturated polyester resin, the anti-sagging and anti-cracking properties of the paint film are improved; at the same time, under the comprehensive action of the remaining components, the unsaturated polyester primer of this application is It has good leveling property, excellent anti-sagging and anti-cracking effect and hiding power, realizes thick coating without sagging, and improves the surface performance of the paint film.

Description

technical field [0001] The application belongs to the technical field of coatings, in particular to an unsaturated polyester primer and a preparation method thereof. Background technique [0002] Coatings are widely used in buildings, wooden furniture, all kinds of hardware, decoration of industrial products, machinery, transportation and other fields. They are indispensable materials for daily production and protection of infrastructure. With the continuous improvement of my country's economic level, the demand for wooden office and furniture products continues to increase, and the use of coatings on their surfaces is also increasing. The film thickness is high, and the paint film is not easy to collapse. It is favored by major furniture manufacturers and has been widely used in the fully enclosed white paint process in furniture manufacturing. When carrying out the fully enclosed white paint process, generally the white primer is sprayed on the substrate first, and then th...
