Abstract

The invention discloses heat-resisting scratch-resisting car paint with modified waterborne polyurethane dispersoid. The heat-resisting scratch-resisting car paint is prepared from, by weight, 100 parts of modified waterborne polyurethane dispersoid, 45 parts of acrylate, 20 parts of alkyd resin, 10 parts of dipropylene glycol butyl ether, 5 parts of organosilicone resin, 4.5 parts of chlorinated rubber, 6.5 parts of chlorcosane, 3 parts of iron oxide red, 3 parts of nitrocotton, 4 parts of high-strength carbon fibers, 6.5 parts of modified wollastonite, 7.5 parts of flaky aluminum sheets, 5 parts of mica powder, 3 parts of graphite powder, 4 parts of zinc oxide, 5 parts of cholamine, 6 parts of diacetone alcohol, 4.5 parts of phthalic anhydride, 4 parts of thickener, 2.5 parts of high-elasticity rubber, 3 parts of bactericide, 4 parts of curing agent, 6 parts of drier, 7 parts of silicone oil and 5 parts of petroleum solvent. The heat-resisting scratch-resisting car paint with modified waterborne polyurethane dispersoid is excellent in heat resisting and scratch preventing performance.

Description

technical field [0001] The invention relates to the field of polyurethane materials, in particular to a modified waterborne polyurethane dispersion heat-resistant and scratch-resistant car paint. Background technique [0002] Car paint is a kind of protective film sprayed on the car. It is a kind of paint, which makes the car body not easy to be corroded, and gives people a kind of aesthetic evaluation. Different car paints have different effects. Main features of performance: good fullness of the paint film, high gloss, high hardness, good adhesion, excellent mechanical properties of the paint film, excellent gloss retention, weather resistance, wear resistance, good acid resistance, resistance Alkali, alcohol and gasoline resistance. [0003] The anti-scratch and heat-resistant properties of automotive paints in the prior art cannot meet the needs of actual use, so it is urgent to develop a scratch-resistant car paint with excellent heat-resistant and anti-scratch propert...
