Problems solved by technology

However, the metal fatigue of aluminum profiles is poor and prone to wear, so the service life of aluminum profiles will be shortened. Moreover, the aluminum in aluminum profiles is highly active and prone to oxidation in the air, forming an aluminum oxide film on the surface of aluminum profiles. Subsequent processing of aluminum profiles

Abstract

The invention discloses an aluminum profile surface modification method. The method comprises the steps as follows: S1, preparing a surface treating agent; S2, washing an aluminum profile with distilled water, wiping the aluminum profile with deerskin cloth, treating the aluminum profile with the surface treating agent, introducing inert gas continuously, performing vacuum drying, and naturally cooling the aluminum profile to the room temperature to finish surface treatment of the aluminum profile; S3, preparing an aluminum profile modifier; S4, spraying the aluminum profile modifier on the surface of the aluminum profile subjected to surface treatment in the S2, and leveling, drying and cooling the aluminum profile to the room temperature to finish modification of the surface of the aluminum profile. The modification method is simple to operate, has low requirement for required equipment, can be applied to industrial production and has wide application ranges. The modified aluminum profile has good wear resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of aluminum profile processing, in particular to a method for modifying the surface of an aluminum profile. Background technique [0002] Due to the advantages of light weight, easy forming, high strength, corrosion resistance, renewable, less pollution, and low maintenance costs, aluminum profiles are widely used in the fields of construction, automobiles, furniture, vehicles, and medical equipment. However, the metal fatigue of aluminum profiles is poor and prone to wear, so the service life of aluminum profiles will be shortened. Moreover, the aluminum in aluminum profiles is highly active and prone to oxidation in the air, forming an aluminum oxide film on the surface of aluminum profiles. Subsequent processing of aluminum profiles. Based on this, the present invention proposes a method for modifying the surface of an aluminum profile. Contents of the invention [0003] The purpose of the present inv...
