Abstract

The invention relates to the field of chemical powder coating, in particular to a crimping powder coating. 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. The crimping powder coating of the invention is composed of base powder and strip agent, and the base powder components of the crimping powder coating comprise epoxy resin, carboxyl resin, barium sulfate, curing agent, solid ammonia, and polyethylene acid. Preparation of the crimping powder coating comprises the following steps: weighing and selecting epoxy resin, carboxyl resin, barium sulfate, curing agent, solid ammonia, and polyethylene acid based on the weight ratio of the base powder components; weighing proper amount of pigments based on the weight of the base powder components; mixing the base powder components and the pigments and fusing and extruding through a extruder; obtaining the base powders after the fused and extruded material are cooled and pulverized into powders; and obtaining the crimping powder coating by uniformly blending the strip agent which is matched and weighted based on the weights of the base powders and the strip agent with the base powders.

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.
