Embodiment Construction

[0010] The method for processing wood grain on an aluminum profile of the present invention includes a process of coating a paint on the surface of an aluminum veneer or an aluminum profile, wherein, in the process of coating a paint on the surface of an aluminum veneer or an aluminum profile , sequentially carry out a pretreatment step, a spraying step and a wood grain transfer step.

[0011] In the pretreatment step, the surface inspection of the aluminum veneer or aluminum profile is carried out first, then the aluminum veneer or aluminum profile is mounted on a shelf, and then chemical degreasing and descaling are carried out. The chemical degreasing and descaling It is realized by applying surfactant and sulfuric acid on the surface of aluminum veneer or aluminum profile, then washing with water, then chromating with chromate, then washing with water again, and finally at a temperature of 80-100 degrees Celsius for 10-20 minutes Drying, in a preferred embodiment of the pr...

Abstract

The invention relates to a method for processing wood grains on an aluminum section, which comprises a step of preprocessing, a step of spray coating and a step of wood grain transfer printing sequentially, wherein in the step of preprocessing, the aluminum section is mounted to perform chemical degreasing and roll scale removal, then the aluminum section is washed in water and chromized by chromate, and is washed in the water again and dried; in the step of spray coating: the aluminum section is hung up to perform dust blowing, wiping, spraying a fluorocarbon prime lacquer and a fluorocarbon top coat, drying and solidification; and in the step of wood grain transfer printing, a transfer printing water tank and a soaking water tank is added with water and heated up first, a wood grain membrane is tiled on the water surface of the transfer printing water tank, and the surface of the aluminum section is contacted with the wood grain membrane so as to transfer the paint on wood grains to the surface of the aluminum section; then the aluminum section is transferred to the soaking water tank; after that the aluminum section is cleaned and wiped clean and dried, and is baked and solidified. The method coats the wood grains on the surface of an aluminum veneer or the aluminum section by a transfer printing method, and solves the technical problem that in the prior art, and the surface of the aluminum veneer or the aluminum section cannot be provided with the wood grains.

Description

Technical field: [0001] The invention relates to the field of chemistry, in particular to metal surface treatment, in particular to a method for processing wood grain on aluminum profiles. Background technique: [0002] In the field of construction, the use of wood-based combustible organic panels is restricted. However, the high-quality decoration and various beautiful wood grains of wooden building materials are still very popular. In the prior art, fluorocarbon aluminum veneers and aluminum profiles are generally used as curtain wall materials in the construction field, but the colors of fluorocarbon aluminum veneers and aluminum profiles are monotonous and cannot replace wood grain and wood color. Invention content: [0003] The object of the present invention is to provide a method for processing wood grains on aluminum profiles. The method for processing wood grains on aluminum profiles should solve the problem that wood grains cannot be processed on fluorocarbon al...
