Abstract

The invention relates to the field of paint, and provides an anti-cracking PE (polyethylene) primer and a preparation method thereof. The PE anti-cracking primer provided by the invention comprises the following components in parts by weight: 40-45 parts of resin, 2 parts of styrene, 0.3 part of dispersing agent, 7-8 parts of titanium white, 0.6 part of anti-settling agent, 27-30 parts of 1250-mesh talcum powder, 18-20 parts of 1250-mesh heavy calcium carbonate, 3 parts of zinc stearate, 1.8 parts of xylene, 0.1 part of defoaming agent and 0.2 part of leveling agent. Compared with the prior art, the PE primer provided by the invention has a favorable film coating effect and excellent anti-cracking performance and can be widely used for furniture painting.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a primer with anti-cracking performance for wooden furniture and a manufacturing and using method thereof. Background technique [0002] Since the advent of PE wood lacquer, because of its excellent high fullness, filling and hardness, etc., it has improved the efficiency of furniture coating and improved the comprehensive performance of the paint film, so it has been widely promoted in the furniture industry. In recent years, with the changes in the furniture market and the transformation of the furniture coating process, the requirements for furniture paint are also getting higher and higher. The application of PE white primer is very extensive. The problem of cracking in the heterogeneous structure of furniture, especially in grooves or carvings, has always troubled many people in the paint industry. As we all know, the grooves and carvings are relatively deep, and it is n...
