Abstract

The invention belongs to the technical field of automobile paints, and particularly relates to a water-based single-component automobile paint containing nanometer titanium dioxide and a preparation method thereof. The water-based single-component automobile paint containing the nanometer titanium dioxide mainly consists of a component A, a component B and a component C, wherein the component A mainly consists of nanometer titanium dioxide, a copolymer dispersion agent containing high-pigment affinity groups, a modified silicon dioxide solution, methyl glycol, an organosilane surfactant and water; the component B is an aliphatic polyurethane dispersion; the component C is a polyurethane associative rheological agent. An automobile paint film prepared by the water-based single-component automobile paint containing nanometer titanium dioxide is flat and bright, and has the advantages of obvious gold and yellow phases, good adhesion force, scratching-resistant property, high glossiness, and excellent aging-resistant and anti-ultraviolet properties. The water-based single-component automobile paint containing nanometer titanium dioxide has the advantages that the heat isolation effectis good, the self-cleaning and dirt-resistant properties are good, and the water-based single-component automobile paint is ideal.

Description

technical field [0001] The invention belongs to the technical field of automobile paints, and in particular relates to a water-based one-component automobile paint of nano titanium dioxide and a preparation method thereof. Background technique [0002] Car paint is the paint that is sprayed on the car. Car paint can not only protect, but also decorate. It can form a protective film on the surface of the car body, making the car body not easy to be corroded and scratched, and can prolong the service life of the car body. At the same time, it can also give people A kind of beautiful enjoyment. Because the car has been exposed to wind and rain all year round, extremely high requirements are placed on the performance of the car paint film as the car's protective film. It not only needs to have good mechanical properties, good fullness, high gloss, but also its attached Higher requirements are put forward for strength, hardness, and scratch resistance. At the same time, it need...
