The corrosion-resistant anti-microbial aluminum-profile rare-earth silane treating fluid is prepared from, by weight, 120-130 parts of CeCl<3>7H2O, 180-190 parts of H2O2, 0.5-0.6 part of poly-sebacic glyceryl monolaurate, 0.3-0.4 part of nano samarium, 0.4-0.6 part of turpentine oil liquid anhydride, 0.4-0.5 part of itaconic acid, an appropriate amount of deionized water, 1-1.2 parts of tetraethyl orthosilicate, 5-5.2 parts of methyl triethoxysilane, 50-53 parts of ethanol, 10-11 parts of ammonia water, 15-15.6 parts of fluorine and silicon-containing polyacrylate emulsion and 2-2.5 parts of nano zirconium dioxide. The compactness of a film formed by the treating fluid is greatly improved, and the film has certain water-repellent performance. The film forming speed is high and the film is uniform and compact by using the poly-sebacic glyceryl monolaurate, the turpentine oil liquid anhydride and the itaconic acid. The antibacterial property, the oxidation resistance and abrasion resistance of the film are improved by using the nano samarium.
Description
Technical field
The present invention relates to chromium-free metal surface treatment agent technical field, particularly relate to a kind of anti-corrosion antiseptic aluminum section bar rare earth silane treatment solution and preparation method thereof.
Background technology
Aluminium surface rare earth conversion film and silane conversion film by extensive concern, and are expected to alternative chromate conversion coating as first-generation metal process for treating surface.Rare-earth conversion coatings has higher bonding strength as inhibiter, and resistance to persistence is good, but easily dehydration cracks, and has a strong impact on corrosion resisting property.And silane conversion film has superhydrophobic property, even compact, effectively can stop medium to be invaded and produce corrosion to matrix, but this rete poor durability, once destroying, corrosion resisting property lost efficacy rapidly.By the mutual supplement with each other's advantages using rare earth silane composite film to achieve above-mentioned two kinds of retes, can to provide effectively for aluminum substrate, the corrosion prevention of environmental protection.Determined the optimal processing parameter of rare earth silane complex film by orthogonal test: CeCl37H2O concentration is 40g/L, and silane concentration is: 3g/L, H2O2 concentration is: 60ml/L, pH are: 4.0, and temperature is: 35 DEG C, film formation time is 10min.Use the analysis means such as scanning electron microscope, EDS, polarization curve, CA tester, the surface topography of the rare earth silane complex film under optimum process condition, chemical constitution, Elemental redistribution, chemical property and hydrophobicity are studied, and have carried out corresponding comparison to simple Cerium conversion film.Research draws, composite film is than simple Cerium conversion film even compact more, and surface does not almost have obvious crackle, compensate for Cerium conversion film and easily to dewater the deficiency of chapping, improve rete overall performance.
But the intensity of this rare earth silane complex film, wear resistance, compactness, erosion resistance are not enough, do not reach the performance of chromate conversion coating, need to improve.
