Problems solved by technology

Traditional water-based thermal insulation coatings have a single color, while the colorful coatings on the market lack thermal insulation functions and poor stability
The traditional water-based multi-color paint is only imitating the color of granite, and the multi-color paint with heat insulation effect rarely appears in the market

Abstract

The invention relates to a colorful multi-layer paint with thermal insulation function and a preparation method thereof. The multi-layer paint comprises a prime paint, a main coating paint and finishing varnish from the inside out. By adding functional fillers to the prime paint and main coating paint, and adding nano thermal insulation slurry into the finishing varnish, the thermal insulation paint with barrier and reflection effects can be prepared. Compared with the prior art, according to the invention, through introduction of the overall functional fillers, the colorful multi-layer paint film can reach thermal insulation effect, thus reducing introduction of external heat to the inside and saving energy; the product has strong crack resistance, through the thermal insulation effect of the external thermal insulation finishing layer, the temperature change range of the external insulation layer can be reduced, and the crack resistance of the external insulation layer can be effectively improved. Through introduction of the functional material, the degradation rate of the coating film can be slowed, and the service life of the coating can be improved.

Description

technical field [0001] The invention relates to a coating, in particular to a multi-color multi-layer coating with thermal insulation function and a preparation method thereof. Background technique [0002] The use of natural granite as decorative materials for building interior and exterior facades is gradually being eliminated due to the lack of mining of natural stone, the damage to the natural environment and pollution of the environment, the natural color difference of stone source mines, and the poor safety of steel hanging stones, etc. Factors, the color effect of replacing natural granite in the form of paint arises spontaneously. [0003] Water-based colorful paint is a hot product used in the field of decorative paint for interior and exterior walls in recent years. The decorative effect is outstanding. The product is sprayed on the surface of latex paint or quartz sand paint by one-time spraying. After drying, it can present a variety of color patterns at the same...
