Abstract
The invention relates to a silane ceramization agent and a preparation method thereof, the silane ceramization agent comprises 1.5%-2.8% of fluozirconic acid, 0.05%-0.15% of hafnium oxychloride octahydrate, 0.3%-0.9% of silane, 0.03%-0.08% of super fine active zinc oxide and 92%-98% of water. When the silane ceramization agent is used, a smooth and neat membrane can be quickly formed without heating, and the color correspondingly changes according to the metal color, and is mainly blue to bluish violet. The formed silane ceramization membrane, compared with a ceramization membrane formed by the ceramization agent in the market, is stronger, high temperature resistant, corrosion resistant, higher in hardness, and better in wear resistance, can prevent metal re-rusting, returning, and has stronger subsequent paint coating adsorption force.
Description
Technical field
The present invention relates to a kind of metal conditioner, especially a kind of excellence be pollution-free, can substitute completely the silane vitrified agent of phosphorization agent.
Background technology
Metal usually needs to carry out some pre-treatment work before application: the techniques such as metallic surface oil removing degreasing, rust cleaning blooming.And in blooming technique, the overwhelming majority adopts phosphorization agent to carry out blooming at present, along with the increase of environmental consciousness, the use of phosphorization agent becomes environmental pressure.Vitrified agent, silane finish continue to bring out in recent years, replace the phosphatize phosphate coat having pollution with without phosphorus film.And pure silane treatment agent is harsh to water quality requirement, uses and be pure water, be difficult to extend range and use; Though pure vitrified agent is in use not high to water quality requirement, the erosion resistance of vitrification film is lower slightly, and 500h neutral salt spray is unstable, and the metal after surface treatment keeps the time not returning rust shorter.
Summary of the invention
According to the shortcoming of pure silane treatment agent and pure vitrified agent, the present invention is in conjunction with the advantage of vitrified agent and silane finish, the composite treating agent of a kind of silane system and zirconium system is provided, when its environmental pollution, process, rust, 500h neutral salt spray good stability by force, is not returned to water quality no requirement (NR), vitrification film erosion resistance.A kind of excellent effect, pollution-free, the silane vitrified agent that can substitute phosphorization agent completely.
This silane vitrified agent contains fluorine zirconic acid 1.5%-2.8%, eight hydration oxychlorination hafnium 0.05%-0.15%, silane 0.3%-0.9%, superfine active zinc oxide 0.03%-0.08%, water 92%-98%; This silane vitrified agent pH value is 2-3.
The invention provides a kind of method preparing silane vitrified agent, comprise the following steps:
(1) get the water of 1/3 weight in formula, and slowly add fluorine zirconic acid, limit edged stirs.
(2) in the solution prepared in step (1), slowly add eight hydration oxychlorination hafniums, limit edged stirs, transparent to dissolution homogeneity.
(3) get the water of 1/3 weight in formula, slowly add silane, limit edged stirs.
(4) in the solution prepared in step (3), slowly add superfine active zinc oxide, limit edged stirs.
(5) slowly added by the solution that step (4) is prepared in the solution that step (2) prepares, limit edged stirs, and is finally added by the water of surplus 1/3 weight, stirs.
The present invention can carry out surface treatment to metal at normal temperatures, and only need adopt 2%-5% of the present invention, now pH value is 4-5, processes in the mode sprayed.
The heavy metals such as the present invention is not phosphorous, chromium, environmentally safe; The silane vitrification film formed is mainly by normal temperatures, super fine zinc oxide utilizes silane as charge-transfer complexation body, carry out improving particle surface, more easily be dispersed in metallic surface, after the increase of metal species more easily makes metallic surface contact vitrification liquid, quick generation redox reaction, take zirconium as nucleus, under the effect of eight hydration oxychlorination hafniums, rapid accumulation forms vitrification film, while vitrification film is formed, silane fast and metal combine closely with the form of covalent linkage, and form three-dimensional netted silane film in metallic surface.Now the silane vitrification film of metallic surface is more solid, high-temperature-resistant and anti-corrosion, 500h neutral salt spray test stable, hardness is higher, and wear resistance is better, can stop metal and return rust, and stronger to follow-up paint coatings adsorptive power.
