Problems solved by technology

If the polyurethane sealing primer is not completely sealed or is pierced during polishing, it is easy to penetrate when it is coated with white unsaturated polyester furniture paint, and the penetration parts of the paint film will have poor hiding power, exposed ribs, dullness, etc., which will seriously affect the quality of furniture. The quality of the topcoat coating film caused a lot of rework of the coating

Abstract

The invention discloses impermeable white unsaturated polyester furniture coating. The impermeable white unsaturated polyester furniture coating comprises a main agent part A, a part B containing cobalt iso-octoate and a part C containing methyl ethyl ketone peroxide, wherein the part A comprises the following components in parts by weight: 40 to 50 parts of unsaturated polyester resin, 0.01 to 0.03 part of a polymerization inhibitor, 7 to 10 parts of titanium dioxide, 25 to 35 parts of an inorganic filler, 3 to 5 parts of zinc stearate, 4 to 10 parts of a solvent, 0.3 to 0.5 part of an anti-settling agent, 0.1 to 0.3 part of a defoaming agent, 0.2 to 0.5 part of a flatting agent, 0.1 to 0.3 part of a dispersing agent, 0.5 to 1.5 parts of nitrocotton and 0.1 to 0.3 part of a stabilizing agent. The impermeable white unsaturated polyester furniture coating adopts nitrocotton, so the technical problems that the coating is easy to permeate and the bar is exposed when a density board which is not closed is coated with the white unsaturated polyester furniture coating, and the rework rate of coating is reduced.

Description

technical field [0001] The invention relates to an unsaturated polyester furniture coating, in particular to an anti-permeation white unsaturated polyester furniture coating. Background technique [0002] Unsaturated polyester furniture coatings can be thickly coated at one time, with full paint film, good hardness, solvent resistance, filling and anti-collapse properties, and are widely used in the furniture industry. In particular, the current popular white panel furniture coating mainly uses unsaturated polyester furniture coatings as primers, and polyurethane white and other solid-color paints as topcoats. Now the panel furniture uses MDF as the base material, first spray a polyurethane sealing primer, and after polishing, apply a thick white unsaturated polyester furniture coating. If the polyurethane sealing primer is not completely sealed or is pierced during polishing, it is easy to penetrate when it is coated with white unsaturated polyester furniture paint, and th...
