Abstract
The invention discloses an anti-corrosion technology for metal surfaces. The technology comprises: mixing compositions such as siloxane, a solvent, silicon dioxide particles, a rear earth compound, deionized water, a catalyst, carbon fiber, polyimide and the like, performing aging processing, then filtering the aged mixture, employing spraying, brush coating or dipping to enable the filtered mixture to be on a substrate surface, after deposition, forming a coating on the substrate surface, so as to realize surface anticorrosion processing.
Description
Technical field
The present invention relates to a kind of aseptic technic of metallic surface, relate in particular to one and be applicable to metal structure surface, there is 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 the destruction of the forms such as crevice corrosion, stress corrosion and the corrosion fatigue especially occurring in the storage vessel of a fuel oil dangerization product, causes great potential safety hazard for people's lives.
The metal protection method adopting at present can roughly be divided three classes: a class is to carry out anodic oxidation treatment, form the anode oxide film of one deck tens micron thick in metallic surface, but because anode oxidation process power consumption is large, and electrolyte solution is seriously polluted, be difficult to process, use its application to be restricted; Equations of The Second Kind is chemical conversion film, be immersed in by metal parts in the solution of definite composition, rely at a certain temperature chemical reaction to form one deck chemical conversion film, now most widely used is the oxidation of chromic salt chemistry, but chromic salt is a kind of carcinogenic toxicant, world environments protective tissue has proposed restriction and has used chromic salt and other to contain chromate compound; The 3rd class is organic coating, applies one deck organic coating in metallic surface, to improve outward appearance and the physical and chemical performance of metal.People start rare earth element to be used in the aseptic technic of metallic surface in recent years.
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 is also improved.At present rare-earth conversion coatings technology is mainly immersion treatment, and this technological operation is simple, be easy to safeguard; But its drawback is, long period of soaking process treatment time is oversize, and the rete forming is thinner and poor with the sticking power of base material.Find through long-term exploratory development, in soaking solution, add strong oxidizer, as H

8etc. strong oxide compound, rate of film build is improved greatly, the treatment time shortens dramatically, and treatment soln temperature is not high yet simultaneously, can at room temperature apply.But because the existence of strong oxidizer makes the less stable for the treatment of process.
The problem existing in order to solve rare-earth conversion coatings treatment process, the present invention proposes a kind of aseptic technic of improved metallic surface.This method anticorrosion with low cost, remarkable in economical benefits, can carry out normal temperature and spread, and coating processes is simple, and solution is environment friendly and pollution-free.
Summary of the invention
The object of the invention is for the deficiencies in the prior art part, provide a kind of coating method of environment friendly corrosion protection coating, in order to solve a protection against corrosion difficult problem for the surfaces externally and internally applications such as steel, aluminium, especially aluminium alloy, and coating aromatic free solvent, not containing strong oxidizer, without poisonous pigment, be applicable to various constructional methods, application is not subject to seasonal restrictions, and construction technology is simple and convenient, technical costs is cheap, good environmental protection.
