Abstract
The invention discloses an anticorrosion process for metal surfaces. Through carrying out curing treatment on a mixture of components such as siloxane, solvents, silica particles, rare earth compounds, deionized water, catalysts, carbon fibers and polyimide, filtering the mixture subjected to curing, and coating the obtained product on the surface of a base material through spray coating, brush coating or soaking, a coating is formed on the surface of the base material after the obtained product is deposited, thereby achieving an effect of surface anticorrosion treatment.
Description
Technical field
The present invention relates to a kind of protective system coating method, relate in particular to a kind of metal structure surface that is applicable to, have the coating method of the environmental protection coating material of excellent gloss and mechanical and physical performance and aromatic free solvent.
Background technology
In modern industry and daily life, corrosion of metal is seen everywhere, and especially the destruction of the forms such as crevice corrosion, stress corrosion and corrosion fatigue that take place in the storage vessel of a fuel oil dangerization product is caused great potential safety hazard for people's lives.
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, now 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.At present 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 base material.Discover through long-term exploration, add strong oxidizer in the soaking solution, as H

8Etc. strong oxide compound, rate of film build is improved greatly, the treatment time shortens dramatically, and the treatment soln temperature is not high yet simultaneously, 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 method.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, provide a kind of coating method of environment friendly corrosion protection coating, in order to solve the protection against corrosion difficult problem of surfaces externally and internally applications such as steel, aluminium, especially aluminium alloy, 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.The present invention is achieved by the following technical solutions:
