Automotive trim special high-insulation coating and preparation method thereof

Abstract

The invention provides an automotive trim special high-insulation coating and a preparation method thereof. The automotive trim special high-insulation coating is prepared from the following raw materials in parts by weight: 50-70 parts of hydroxy acrylic resin, 6-10 parts of cellulose acetate butyrate liquid, 1-3 parts of polyethylene wax, 2-6 parts of dispersing agent, 2-6 parts of pigment, 1-4parts of extinction powder, 0.1-0.6 part of leveling agent, 8-10 parts of ethyl acetate and 8-10 parts of butyl acetate. Compared with the prior art, the coating provided by the invention does not contain volatile organic compounds, the cross-linking density after curing is large, the performance indexes of a coating in various aspects such as hardness, wear resistance, acid and alkali resistance,salt mist resistance and gasoline resistance are very high, especially the paint film insulativity is very good, and when the voltage of a multimeter is 1000V, the resistance can reach 50G ohm or above. And moreover, during spraying, the coating is good in dispersity, moderate in leveling property, moderate in thixotropy, uniform, free of obvious orange peel, free of needle eye bubbles, free of impurity points and good in smoothness.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a special high-insulation coating for automobile interior decoration and a preparation method thereof. Background technique [0002] Nowadays, with the increase of people's income and the improvement of the quality of life, every household will buy and use cars for transportation. Then comes the safety issue when riding. Many places in the car interior space need to be equipped with electrical equipment: such as electronic buttons, central control instruments and gear bases, etc., will be connected by wires. These painted electronic devices bring comfort and convenience to people, but at the same time there are potential safety hazards. If there is a leakage of electricity, it is easy to cause abnormal failures of electronic devices or even cause a short circuit to cause spontaneous combustion of the vehicle. For this reason, a high-insulation paint has been developed. To pai...

Problems solved by technology

These painted electronic devices bring comfort and convenience to people, but at the same time there are potential safety hazards. If there is a leakage of electricity, it is easy to cause abnormal failures of electronic devices or even cause a short circuit to cause spontaneous combustion of the vehicle. For this reason, a high-insulation paint has been developed. To paint these parts, to avoid accidents caused by line leakage to the greatest extent
