Bisphenol A epoxy resin modified bifunctional polyester acrylate UV (ultraviolet)-transparent primer for wooden furniture and preparation method thereof

Abstract

The invention provides a bisphenol A epoxy resin modified bifunctional polyester acrylate UV (ultraviolet)-transparent primer for wooden furniture, which comprises the following components in percentage by weight: 30-55% of bifunctional polyester acrylate, 0.1-0.3% of wetting and dispersing agent, 0.3-0.5% of defoaming agent, 18-40% of filler, 8-20% of monomer, 0.3-0.6% of leveling agent, 1-3% of bisphenol A epoxy resin and 3-10% of initiator. The primer has the advantages of favorable color, favorable transparency, favorable glossiness, low cost, stable properties and high storability; and the primer film has the advantages of short drying time, favorable transparency, high glossiness, favorable fullness and excellent mechanical properties. The invention also provides a preparation method of the transparent primer. The method has the advantages of simple technique, simple operation, favorable repetitiveness, short production cycle and high production efficiency, and is very suitable for industrialized production.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a bisphenol A type epoxy resin modified difunctional polyester acrylate UV transparent primer for wooden furniture and a preparation method thereof. Background technique [0002] UV paint is a light-curing paint. It is currently a widely used furniture paint. Its main features are: low energy consumption, no pollution, green environmental protection, mechanized production, less personnel requirements, and high cost. Therefore, it is used in cabinets, wooden doors, furniture, etc. widely. [0003] In recent years, the use of UV paint for wooden furniture has developed rapidly, gradually replacing traditional sprayed alkyd paint and unsaturated polyester paint. Traditional alkyd paint and unsaturated polyester paint will release a large amount of organic solvents to pollute indoor air and atmosphere , the overall production efficiency and benefits are not high.

AI Technical Summary

Problems solved by technology

[0005] However, the defects of UV paint are obvious, especially poor adhesion and insufficient fullness, which is one of the reasons why UV paint cannot be widely used. The adhesion of UV transparent primer is not only manifested in the adhesion between the paint and the substrate, but also On the adhesion between coating and coating

[0006] Moreover, the existing transparent primer production process is complicated, the production efficiency is low, and the raw material cost is high
