Description
Technical field
The present invention relates to a kind of transparency protected Rotating fields of the coat of metal and process thereof.
Background technology
In recent years, along with automobile, household electrical appliance and corresponding decoration industrial expansion and people are to beautifying the raising day by day of life requirement, the dicoration of product and decay resistance etc. are required to improve the most further by industrial operation person.Surface metallization technology is to utilize that the marginality new technique of the subjects such as modern physics, metallography and electrochemistry interpenetrates, crossing one another changes the organizational structure of product surface or deposit one or more layers metal film on original surface, to reach property as obtained the process with metal finishing outward appearance etc. of workpiece.Surface coating technique is the important component part of Surface Engineering and Rebuilding engineering, currently mainly includes Vacuum Deposition, chemical plating, plating and Brush Plating etc..
Due to the coat of metal the most relatively thin (0.05 μm～5.0 μm), cause the surface of part metals ripple the most alive metal such as aluminum, silvering to be vulnerable to external influence such as light, oxygen, soda acid, scratch and occur variable color, aoxidize, the phenomenon such as rotten and damage.In order to improve the colour stability of coating, corrosion resistance and the character such as wear-resisting; dealer would generally take chemical passivation, electrochemical passivation or plate the method such as alloy of the noble metals such as a layer of chemically stable gold, palladium, rhodium, indium or noble metal again, but these methods all exist complex process, improve limitation and high in cost of production shortcoming limits its application.By simple dipping, spraying or electrophoresis process coating surface formed one layer of fine and close organic polymer transparent lamina just can effectively mask erosion medium, improve surface abrasion resistance, prevent variable color.But the organic solvent in most of macromolecular solutions, monomer, firming agent etc. can occur serious variable color even to destroy the phenomenons such as coating after contacting with coating particularly Vacuum Deposition, chemical plating metal coating in actual mechanical process.Although the most a small amount of water soluble polymer clear solution will not occur the phenomenon such as coating color, damage after contacting with the coat of metal; but owing to being exposed in air after this kind of macromolecule filming; the moisture in air can be adsorbed; causing protective layer character to be deteriorated, affecting matrix particularly has the stability of ferrous components matrix.
The most how to find one the easiest, the most do not destroy coating and cost but also low transparent protective layer technology, there is important practical significance.
