Abstract
The invention relates to a coating for surface treatment of automobile parts. The coating is prepared from components in percentage by mass as follows: 10%-20% of polyacrylamide, 15%-45% of cyclohexanone, 10%-40% of aluminum tripolyphosphate, 1%-7% of dry powder type sucrose, 3%-13% of boric acid, 0.1%-1% of polyacetate latex, 1%-9% of propylene glycol butyl ether, 1%-10% of polyurethane and the balance of deionized water. Leather treated with the coating has excellent facile hand feeling, chemical resistance and wear resistance, has high stretch and elongation, is water-resistant, moisture-resistant and uvioresistant, doesn't yellow and is high in gloss. The coating resin has high elasticity and good adhesion force for the automobile part surfaces.
Description
Technical field
The invention belongs to car surface processing technology field, specifically relates to a kind of auto parts surface spraying coating.
Background technology
Enter to be frequently necessary to carry out diversified process in auto parts surface, so as to improve piece surface performance, it is facilitated to use as needed, general piece surface processing mode, it is mostly to be carried out by coating spraying, and in general dope preparing process, need to be configured using different coating raw materials, so as to improve coating using effect.
The content of the invention
It is an object of the invention to provide a kind of auto parts surface spraying coating, the coating has film forming soft, and the effect of bloom has splendid submissive feel to corium.
To reach above-mentioned purpose, the specific technical scheme of the present invention is as follows：
A kind of auto parts surface spraying coating, its formula is calculated by mass percentage, composed of the following components：Polyacrylamide：10～20%；Cyclohexanone：15～45%；Aluminium triphosphate：10～40%；Dry powder-shaped sucrose：1～7%；Boric acid：3～13%；Poly-vinegar acid esters latex：0.1～1%；Propylene glycol n-butyl ether：1～9%；Polyurethane：1～10%；Remaining is deionized water.
Its concrete preparation technology is as follows：
（1）First by polyacrylamide, cyclohexanone input reactor, 110～120 DEG C are heated to, then vacuumize dehydration 30～60 minutes；
（2）Said mixture is cooled to into 85 DEG C, adds organo-bismuth Cui agent to stir 10 minutes；
（3）Add aluminium triphosphate in said mixture again, maintain 70～90 DEG C of temperature to be incubated 120～180 minutes；
（4）Then dry powder-shaped sucrose, boric acid and appropriate ether are added in above-mentioned temperature compound, maintains the insulation 180～240 minutes of 70～90 DEG C of temperature to continue to react；Sampling detection isocyanate group content（NCO）So as to content maintains 0.5～4.3%；
（5）Then said mixture is cooled to into 40 DEG C, adds propylene glycol n-butyl ether and ether, stirred 10～30 minutes；
（6）While above-mentioned stirring, addition has mixed the deionized water of polyurethane；
（7）Continue to stir 60～120 minutes, vacuum pumps ether, you can obtain finished product.
The beneficial effects of the present invention is：In the invention, the corium processed with the coating has splendid submissive feel, and chemical resistance is wear-resisting, with high stretching, high elongation rate, water-fast moisture-proof, uvioresistant, non yellowing, bloom；This coating resin has high-tension to auto parts surface, and adhesive force is good.
