Abstract
An antirusting agent for surface of metal is prepared from phytic acid (0.5-10 wt%), phytate (0.5-3 wt%), solvent (rest) and optional tartaric acid (0.1-1%) for uniform filming, and features uniform and compact filming on the metal surface, high hardness, adhesion, strength and antioxidation nature of its film, no corrosion, cyclic regeneration and reuse, and no environmental pollution.
Description
The present invention relates to a kind of anti-rust agent for treatment of metal surface, and the using method of this treatment agent.
The protection against corrosion of phytic acid is gained public acceptance by people, but phytic acid itself is made costliness, can not get extensive effect always.Phytic acid itself is one of biological activity, has a lot of unusual character, and just people fail deeply to go to observe, and only feels expensive, does not go to use.
In metallic surface complex reaction process, iron in the metal and other non-ferrous metal and oxide compound thereof consume phytic acid soon, its pH value constantly rises, the derivative of a large amount of phytic acid sinks, though constantly add phytic acid in the reaction process but still be not enough to remedy, cause the reaction solution muddiness,, can not use though constantly filter.Iron and steel and various alloy thereof are that surperficial anti-rust agent for treatment is handled its surface with acid phosphate generally, phosphatize phosphate coat necessarily antirust to be formed with, anti-corrosion effect, but this membrane crystallization is more not coarse and contain crystal water, poor with the body associativity, fragility easily takes place peels off, corrosion will take place after for some time, this film and enamelled coating associativity are poor, lacquer easily peels off, and when carrying out membranization and handling, the concentration of treatment agent, treatment time must strictly be controlled, otherwise can cause corrosion to body, influence the mechanical property of body.In addition, this treatment agent tool corrodibility, higher to equipment, the environmental requirement of producing and use, waste liquid can produce problem of environmental pollution, and transportation, the storage requirement of finished product are also had relatively high expectations.
The object of the present invention is to provide that a kind of good film-forming property, rust-preventing characteristic are strong, easy to use, non-corrosiveness, do not cause the anti-rust agent for treatment of metal surface of environmental pollution, and use this treatment agent the metallic surface to be carried out the method for various processing.
The object of the present invention is achieved like this: anti-rust agent for treatment of metal surface of the present invention is mainly by phytic acid, phytate, solvent composition, and wherein the each component weight percent is phytic acid 0.5%～10%, phytate 0.05～3%, and surplus is a solvent.Through evidence; when containing trace metal ion in the plant acid solution; can produce stronger membranization effect to the metallic surface; can form one deck densification, even, hard and do not contain the grey black look protective membrane of crystal water in the metallic surface, this film and body have associativity preferably, and stronger resistance of oxidation is arranged; and this treatment agent non-corrosiveness; but the effect of shield ring can not cause problem of environmental pollution, thereby realizes purpose of the present invention.
Above-mentioned phytic acid content is preferably 1%～4%, and the best is 4%.
Above-mentioned phytate is generally a kind of in phytic acid ca, phytic acid zinc, phytic acid copper, phytic acid manganese, phytic acid titanium, phytic acid vanadium, phytic acid chromium, phytic acid germanium, the phytic acid nickel or several, wherein comparatively commonly used with phytic acid ca, phytic acid zinc, phytic acid manganese, the add-on preferred range of phytate is 0.1%～1%.
Above-mentioned solvent is the aqueous solution, preferably deionized water solution.
In order to improve the one-tenth film uniformity of treatment agent, also can add tartrate, its add-on is 0.1%～1%.
Use above-mentioned treatment agent to do various antirust processing to the metallic surface, its method is specific as follows:
1, the metallic surface film forming is made priming paint.Metalwork after conventional surface treatment, is handled with this treatment agent, taken out after the film forming, metalwork is carried out surface modulation handle, dry afterwards, spraying paint gets final product.Above-mentioned treating processes can at room temperature be carried out, as the need faster processing time, then can suitably heat as required, with 55 ℃～75 ℃ be good, to adopt phytic acid ca or phytic acid zinc be good to the phytate of treatment agent in this treatment process.After adopting present method to handle, the metal layer of paint combine with prime coat firmly, difficult drop-off, long service life, and owing to paint rete tightly, even, layer of paint surface smoothness height is suitable as the prime treatment of sedan limousine, furniture, household electrical appliances.
2, the metallic surface derusting rust-proofing is handled: the metalwork of corrosion is handled with this treatment agent after deoiling, washing pre-treatment, takes out after the film forming, metalwork is carried out surface modulation handle, and through sealing treatment, gets final product after the drying.Above-mentioned treating processes can at room temperature be carried out (more than 0 ℃), as the need faster processing time, then can suitably heat as required, and heating is good with 70 ℃～85 ℃ generally, and in this treatment process, it is good that the phytate of treatment agent adopts phytic acid zinc, phytic acid ca, phytic acid manganese.
3, blackening metal surfaces is handled: through deoiling, after the pre-treatment such as polishing, handling with this treatment agent, take out film forming blackout back, and metalwork is carried out the surface modulation processing, gets final product after surperficial sealing treatment, drying with metalwork.Above-mentioned treating processes can at room temperature be carried out (more than 0 ℃), as the need faster processing time, then can suitably heat as required, heat is good with 75 ℃～100 ℃ generally, in this treatment process, the phytate of treatment agent is preferable with phytic acid manganese, and it becomes film hardness higher, and the surface blackening that is suitable for the instrument series products is handled.
In addition, for the ease of storing, transporting, treatment agent of the present invention can be made concentrated type, is diluted to normal usage ratio by the user according to explanation again when specifically using.
The present invention has following advantage through evidence: metallic surface film forming densification, even, hard, thickness is moderate, combine firmly with body, do not contain crystal water, therefore have higher intensity, good oxidization resistance, long service life, surface smoothness is good, and corrosion-resistant is strong, be widely used in the antirust processing in metallic surface of every profession and trades such as automobile, machinery, electrical equipment, and the treatment agent non-corrosiveness, low to equipment, the environmental requirement of producing, use, produce, use easy to operate, transportation, store convenient; Treatment agent can be recycled, and liquid waste disposal is simple, can not produce environmental pollution problems, has good social benefit and economic benefit.Therefore, the positively effect that the present invention produced is conspicuous.
