The preparation method of above-mentioned non-ferrous metal surface treatment agent, the steps include:
A () gets the mixing of 5-8 part sodium polyacrylate, 1-5 part trisodium phosphate, 0.5-2 part carboxymethyl cellulose and 1-3 part sodium laurylsulfonate by mass fraction, add 70-80 part deionized water, stir, be under agitation heated to 45 DEG C, insulation 30min;
B solution that step (a) obtains by () is cooled to 25 DEG C, adds 3-8 part chitosan and 7-12 part aluminum oxide, stirs 20min;
Add 3-5 part acetic acid and 1-3 part trolamine in c solution that () obtains to step (b), stir and obtain non-ferrous metal surface treatment agent.
3, beneficial effect
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is made up of sodium polyacrylate, sodium phosphate, carboxymethyl cellulose, sodium laurylsulfonate, acetic acid, chitosan, aluminum oxide, trolamine and deionized water, the present invention is used to carry out metallic surface processing oxidation, the corrosion that effectively can prevent metal, keep metallic surface light, and environmentally safe, degradable, cost is low;
(2) the present invention uses nano level aluminum oxide, can form the protective membrane of one deck densification, effectively prevent external environment to the infringement of metal in metallic surface;
(3) trisodium phosphate of the present invention's use is except having derusting action, tensio-active agent sodium polyacrylate can also be made to reduce surface tension and interfacial tension further, sodium polyacrylate is a kind of tensio-active agent with multifrequency nature, can fixing metal ions, insensitive to temperature variation, stability is fine;
(4) low, the degradable of cost of the present invention, use safety, environmentally safe, is conducive to well promoting the use of.
Embodiment
Specific embodiment introduces the present invention in detail below.
