Problems solved by technology

However, there are some problems in the specific implementation process of the wear-resistant coating prepared only by using PVC resin, plasticizer, tackifier and inorganic powder. For example, after coating and standing for 24 hours, the coating is prone to sag and The phenomenon of slipping will cause some inconvenience to the construction
The reason for slipping and sagging is that the interface between the coating and the electrophoretic plate and the bonding force between the components of the coating are insufficient, but there is no suitable technical solution in the prior art. According to the anti-sagging measures of the above-mentioned prior art, a reasonable choice of solvent , it is difficult to solve this problem by improving the spraying method and controlling the construction viscosity, and it is difficult to really effectively solve the problems involved in adjusting the formula only by adding anti-sagging additives.

Abstract

The invention discloses an automobile wear-resistant paint and a preparation method thereof. The preparation method comprises the following steps: adding 100 parts by weight of PVC and 115 to 125 parts by weight of plasticizer into a reactor, evenly mixing; adding 1 to 6 parts by weight of silane coupling agent and 0.001 to 0.01 part of azodiisobutyronitrile into the reactor, increasing the stirring speed to evenly stir the mixture; adding 0.3 to 0.8 part by weight of organic fluorine surfactant and 2 to 8 parts of tackifier into the reactor, fully stirring until the added materials are evenly mixed; adding 250 to 300 parts of inorganic powder, increasing the stirring speed; and vacuumizing to remove the gas after the inorganic powder is evenly dispersed so as to obtain the automobile wear-resistant paint. The automobile wear-resistant paint has the excellent flame retardant performance, anticorrosion performance, and electric insulation performance, and high mechanical strength of polyvinyl chloride resin paint, and also has a very good anti-dropping and anti-sagging performance at the same time.

Description

technical field [0001] The invention relates to a coating for automobiles, in particular to a wear-resistant coating for automobiles and a preparation method thereof; Method for improving the anti-slip and anti-sag properties of coatings. The paint is generally sprayed on the wheel covers, floor panels, side beams, fenders, door pedals and other parts of the car. Background technique [0002] With the rapid development of society and the rapid progress of science and technology, the relationship between cars and humans has become more and more closely related. However, when the car is running, its wheel covers, floor panels, side beams, fenders, and door pedals are easily impacted by sand and stones, which can easily damage these parts and cause corrosion, thereby bringing hidden dangers to driving. Therefore, it is very important and necessary to protect these parts of the car, and the commonly used protection method is to coat these parts with wear-resistant paint. [0...
