Problems solved by technology

However, because the metal is relatively active and easy to oxidize, its production process is only after pretreatment, and then it is solidified by electrostatic spraying. Spraying paint or plastic spraying, the production cost is high and the equipment is complicated by this process, but the product is easy to age, change color, not resistant to chemical corrosion, easy to be stained with oily smoke, and the paint film is easy to burn in a certain environment (high temperature, freezing, environmental pollution) Peeling, discoloration, loss of gloss, easy to fall off and powder
In the patent application number 99104639.0, the patent discloses "a method for making decorative patterns on aluminum alloy plates", which has the disadvantages that it can only be processed on aluminum plates, the process control is difficult, the quality is difficult to guarantee, and the cost is high.

Abstract

A process for coating on the surface of metal material and then preparing pattern on it includes such steps as immersing metal material in solution of H2SO4, water flushing, drying, coating acetone, benzene and n-propyl acetate, blowing surface by air compressor, baking, electrostatic spraying of polyester epoxy powder, baking, making pattern with the mixture of epoxy resin powder, butyl acetate and pigment by rolling or manually, baking and spraying BJS varnish. Its advantages are low cost, high resistance to chemical corrosion and oxidation, and clear 3D pattern.

Description

1. Technical field [0001] The invention relates to a metal material surface treatment and decoration technology, in particular to a metal material surface coating treatment and pattern making method. 2. Background technology [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for their own life and production fields. For example, metal materials used in interior decoration, metal materials used in home appliances, and metal materials used in automobile shells have proposed new solutions. Require. However, because the metal is relatively active and easy to oxidize, its production process is only after pretreatment, and then it is solidified by electrostatic spraying. Spraying paint or plastic spraying, the production cost is high and the equipment is complicated by this process, but the product is easy to age, change color, not resistant to chemical corrosion, easy to be stained with oily smoke, and...
