Aqueous crackle coating

Abstract

The present invention relates to an aqueous crackle coating characterized by comprising: a primer and a topcoat, wherein the primer comprises the following components, by weight: water-dispersible cationic epoxy resin 40-95%, an aqueous sterilizing agent 0.1-0.4%, an aqueous antifoaming agent 0.03-0.2%, a water-based color paste 0-10%, and the balance water; and the topcoat comprises the following components, by weight: water 30-45%, an aqueous multifunctional additive 0.05-0.3%, an aqueous dispersant 0.2-0.4%, an aqueous wetting agent 0.1-0.2%, the aqueous antifoaming agent 0.05-0. 4%, an aqueous matte powder 8-15%, titanium dioxide 0-20%, a room temperature self-crosslinking acrylic emulsion 27-45%, dipropylene glycol butyl ether 0.6-1.5%, an aqueous sterilizing agent 0.1 -0.4%, a water-based color paste 0-10%, and the balance water. The aqueous crackle coating of the present invention is environmentally friendly, safe and no hidden trouble, and has a good adhesion to various substrates, and a good flexibility; the film feels fine and smooth, and by adopting the aqueous crackle coating of the invention, one can choose whether a finish coat is needed or not according to the actual situation.

Description

technical field [0001] The invention relates to a water-based crack paint, which is a paint developed in comparison with the existing oil-based crack paint. Background technique [0002] At present, oil-based crack paint is widely used in home decoration and middle-to-high-end handicraft decoration with its beautiful pattern and elegant decoration. However, it itself contains solvents, so it should be diluted with a large amount of organic solvents containing benzene, alcohols, esters or ketones, which is very harmful to environmental pollution and human health, and is a flammable and explosive product, which is harmful to production There are fire hazards in the construction site. In addition, the oil-based cracked paint has poor adhesion after forming beautiful lines, and the paint film feels poor and not delicate. It must be covered with a top coat to ensure the durability of the lines. Contents of the invention [0003] The purpose of the present invention is to prov...
