Abstract
The invention discloses a coating process of an anticorrosive paint, and relates to a coating process of a magnesium alloy foil explosion-proof material. The coating process comprises the following steps of: mixing siloxane, a solvent, silica particles, a rare earth compound, deionized water, a catalyst, carbon fibers, polyimide, etc.; curing; filtering the cured mixture; spraying, coating with a brush or dipping to the surface of an explosion-proof substrate; and then depositing on the surface of the explosion-proof substrate to form a coating, thus realizing anti-corrosive treatment for the surface.
Description
Technical field
The present invention relates to a kind of protective system coating processes, relate in particular to the tinsel explosion-proof lamp, the coating processes of magnesium alloy paper tinsel explosion-proof lamp particularly, this method is used the environmental protection coating material of aromatic free solvent.
Background technology
In modern industry and daily life; corrosion of metal is seen everywhere; especially crevice corrosion, stress corrosion and the corrosion fatigue, the particularly destruction of the forms such as corrosion of metal explosion-proof lamp that takes place in the fuel oil dangerization product storage vessel causes great potential safety hazard for people's lives.The manufacturing process of described metal explosion-proof lamp generally includes: ingot casting, be rolled into paper tinsel, grooving machine joint-cutting, drawing and forming Web materials.
The metal protection method that adopts can roughly be divided three classes at present: a class is to carry out anodic oxidation treatment, namely form the anode oxide film of one deck tens micron thickness in the metallic surface, but because the anode oxidation process power consumption is big, and electrolyte solution is seriously polluted, be difficult to handle, use its application to be restricted; Second class is chemical conversion film, being about to metal parts is immersed in the solution of definite composition, rely on chemical reaction to form one deck chemical conversion film at a certain temperature, wherein most widely used is the oxidation of chromic salt chemistry, but chromic salt is a kind of carcinogenic toxicant, and the world environments protective tissue has proposed restriction and used chromic salt and other to contain chromate compound; The 3rd class is organic coating, namely applies one deck organic coating in the metallic surface, with outward appearance and the physical and chemical performance that improves metal.People begin rare earth element is used in the aseptic technic of metallic surface in recent years.
The rare-earth conversion coatings film technique develops into today, and people have carried out a large amount of improvement to various film-forming process, and the performance of film also is improved.The rare-earth conversion coatings technology mainly is immersion treatment, and this technological operation is simple, be easy to safeguard; But its drawback is that the long period of soaking process treatment time is oversize, and formed rete is thinner and relatively poor with the sticking power of explosion-proof base material.Discover through long-term exploration, in soaking solution, add strong oxidizer, as H
2O
2, KMnO
4, (NH

2S
2O
8Etc. strong oxide compound, rate of film build is improved greatly, the treatment time shortens dramatically, and simultaneously the treatment soln temperature is not high yet, can at room temperature use, but because the existence of strong oxidizer makes the less stable for the treatment of process.
In order to solve the problem that the rare-earth conversion coatings treatment process exists, the present invention proposes a kind of improved protective system coating processes.This method anticorrosion with low cost, remarkable in economical benefits can be carried out normal temperature and be spread, and coating processes is simple, and solution is environment friendly and pollution-free.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art part, a kind of coating processes of environment friendly corrosion protection coating is provided, in order to solve the tinsel explosion-proof lamp, especially the protection against corrosion difficult problem of magnesium alloy paper tinsel explosion-proof lamp external coating, and coating aromatic free solvent, do not contain strong oxidizer, do not have poisonous pigment, be fit to various constructional methods.Application is not subject to seasonal restrictions, and construction technology is simple and convenient, and technical costs is cheap, good environmental protection.
