High-temperature-resistant coating for automotive upholstery and preparation method of high-temperature-resistant coating

Abstract

The invention belongs to the technical field of high-temperature-resistant coatings, and particularly relates to a high-temperature-resistant coating for automotive upholstery and a preparation methodthereof. The high-temperature-resistant coating is prepared from, by weight, 30-60 parts of organic silicon resin, 4-7 parts of epoxy resin, 3-5 parts of amino resin, 6-10 parts of nano zirconium oxide dispersion liquid, 1-3 parts of aluminum tripolyphosphate, 13-15 parts of low-melting-glass powder, 3-8 parts of talcum powder, and 2-5 parts of mica powder. The heat resistance of the prepared high-temperature-resistant coating is obviously improved, the high-temperature-resistant coating can resist the high temperature of 500 DEG C, the coating has high strength and good high-temperature resistance and wear resistance by adding the nano zirconium oxide dispersion liquid component, and the coating has excellent weather resistance and corrosion resistance by adding the aluminum tripolyphosphate and the low-melting-point glass powder component; and by adding the barium sulfate and the nano zirconium diboride, the wear resistance, the high temperature resistance and the corrosion resistance of the coating are further improved, and the comprehensive performance is excellent.

Description

technical field [0001] The invention relates to the technical field of high-temperature-resistant coatings, in particular to a high-temperature-resistant coating for automotive interior parts and a preparation method thereof. Background technique [0002] With the development of industrial economy and urbanization, my country's automobile production and sales have ranked first in the world for seven consecutive years, becoming the world's largest automobile production and sales country.
