Abstract

The invention relates to crimping powder coating which is applied to the surface painting of electrical control cabinets, industrial sewing machines and other mechanical and electrical products. The invention aims to provide the crimping powder coating which can not be affected by thickness of the metal plate and rise speed of baking temperature to overcome the defects of the existing crimping powder coating that nonuniform texture is caused by the over slow baking temperature rise when thicker and thinner plates are painted. The crimping powder coating provided by the invention consists of base powder and a strip agent, and the base powder components of the crimping powder coating comprise epoxy resin, carboxyl resin, barium sulfate, calcium carbonate, a curing agent, quaternary ammonium bromide, polyvinyl butyral, and pigments. The preparation of the crimping powder coating provided by the invention comprises the following steps: weighing the base powder components and the strop agent; mixing the base powder components uniformly, and fusing and extruding through an extruder; cooling and smashing the extrudate into powders, thus the base powder is obtained; and adding the strip agent in the base powder, and mixing uniformly, thus the crimping powder coating is obtained.

Description

technical field [0001] The invention relates to the field of chemical powder coatings, in particular to a wrinkled powder coating applied to the surface coating of electric control cabinets, industrial sewing machines and other electromechanical products. Background technique [0002] Wrinkle powder coating is widely used in the surface coating of electric control cabinets, industrial sewing machines and other mechanical and electrical products. Existing wrinkled powder coatings are only used for product coating of thin plates, and it is required that the heating rate of the baking temperature be fast when coating the thin plates. In use, the existing wrinkled powder coatings have the following disadvantages: (1) when coating die-casting parts such as industrial sewing machines or other thicker metal plates, the texture is uneven; (2) when coating thin plates When painting, when the baking temperature rises too slowly, it will cause uneven texture.
