Abstract

The invention discloses a polyurethane (PU) crackle paint, and a preparation method of a corresponding primary paint, belonging to the technical field of paint application and resolving defects such as poor solvent resistance, poor adhesion force and difficult control of textures. The invented paint comprises the primary paint, a curing agent and a diluting agent, wherein the primary paint is constituted by 15-30% of alcohol acid resin by weight, 0.5-1% of an orientational alignment agent, 9-15% of a crackle agent, 30-50% of a solvent, 5-15% of a crackle assistant and 2-30% of pigment filler. The paint disclosed by the invention is featured with good adhesion force, good solvent resistance, easy cracking and perfect texture effects.
