Embodiment 1

[0032] A spraying preparation method for processing aluminum profiles, comprising the following steps:

[0033] S1. Substrate pretreatment: pretreat the aluminum profile before spraying, derust the rust layer and rust spots on the surface of the aluminum profile, use equipment to remove the welding points and welding slag of the aluminum profile, and use a rust remover To remove the rust layer and rust spots on the surface of aluminum profiles, high-efficiency corrosion inhibitors are added to the rust remover, and the welding points and welding slag are removed by grinding equipment, and the dust collection equipment is used to reduce dust flying while grinding;

[0034] S2. Water washing and alkali washing: Pour pure water and cleaning agent into the cleaning equipment. The cleaning agent is an industrial degreasing cleaning agent. Put the aluminum profiles into the cleaning equipment for cleaning. After cleaning, put the aluminum profiles in the aluminum washing tank for use...

Abstract

The invention relates to the field of aluminum profile spraying, in particular to a spraying preparation method for aluminum profile processing. The method comprises the following steps that S1, basematerial pretreatment is conducted, specifically, an aluminum profile is pretreated before spraying, rust layers and rust points on the surface of the aluminum profile are removed, and welding pointsand welding slag of the aluminum profile are ground and removed through equipment; S2, water washing and alkali washing are conducted, specifically, pure water and a cleaning agent are poured into cleaning equipment, the aluminum profile is placed into the cleaning equipment to be cleaned, after cleaning, the aluminum profile is placed into an aluminum washing tank to be subjected to alkali washing through alkali liquor, pure water is used again for thoroughly cleaning the aluminum profile, and the aluminum profile is aired after water washing; and S3, chromizing treatment is conducted, specifically, a chromizing solution is used for reacting with the aluminum profile, and a protective layer is formed on the surface of the aluminum profile. According to the method, a spraying primer has high adhesive force, toughness and hardness, the surface adhesive force of finish paint is extremely high, fluorocarbon varnish has super weather resistance, the fluorocarbon varnish takes fluororesin as a base material, the durability and the anti-ultraviolet function are high, and the paint surface of the aluminum profile is prevented from discoloring.

Description

technical field [0001] The invention relates to the field of spray coating of aluminum profiles, in particular to a spray coating preparation method for processing aluminum profiles. Background technique [0002] With the rapid development of economy and high technology, the aluminum smelting and aluminum profile processing industries have developed rapidly. Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. After spraying treatment, their corrosion resistance can be improved. resistance, heat resistance and wear resistance, increase its thickness or repair the size, etc. [0003] When the aluminum profile is sprayed, the adhesion of the sprayed paint surface needs to be improved. After a long time of use, the paint surface will change color, and bubbles and wrinkles on the surface of the aluminum profile will easily occur. The bonding force between the sprayed layer and the surface of the al...
