Abstract

[0002] A corrosion-resistant coating is a special coating used to protect substrates (such as metal, concrete or wood) from corrosive environments; corrosion is the deterioration process of materials due to reactions with chemicals in the environment (such as water, oxygen, salt, and acids or bases); and corrosion-resistant coatings extend the service life of the material and maintain its performance by forming a barrier on the surface of the material to prevent corrosive substances from contacting the material.
[0003] Most corrosion-resistant coatings require a mixture of multiple raw materials, such as epoxy resins and polyurethanes as film-forming materials, as well as pigments, solvents, fillers, and additives to improve specific properties of the coating. In existing production, most raw materials are directly poured into a barrel and then stirred and mixed. However, during the stirring and mixing process, due to the high viscosity of the mixture and the fixed stirring direction and speed, the stirring force on the inner wall of the barrel is small, and the raw materials are easily adhered to the barrel wall, resulting in uneven mixing, affecting the quality of the finished coating material. At the same time, it is difficult for staff to clean up the adhesion, resulting in high production costs and low production efficiency. Utility Model Content
