Abstract

The invention provides a fireproof heat-insulating inorganic mineral coating for buildings and a preparation method thereof. The coating is formed by compounding and processing aerogel, hollow microspheres, high-fire-resistance resin, an inorganic cementing material and other auxiliaries. The nano silicon aerogel is the best thermal insulation material at present; the glass hollow micro-beads andthe ceramic vacuum micro-beads also have excellent heat insulation effects, so that by matching the components with aerogel, the thermal insulation performance is improved; meanwhile, the volume weight of the coating is reduced as a filler, the thermal insulation effect is more remarkable, the void ratio of a coating system is guaranteed by blending silica sol and silicone acrylic resin; furthermore, the strength and the fireproof performance of a coating film are also guaranteed. The invention also provides a composite coating using the coating, the thermal insulation putty adopts an inorganic gelling system taking expanded and vitrified micro bubbles as light aggregate, has excellent thermal insulation performance, has superstrong thermal insulation capability, A-grade fireproof capability and high temperature resistance, and well controls the cost.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation coatings, in particular to a building fireproof and thermal insulation inorganic mineral coating and a preparation method thereof. [0002] technical background [0003] In the trend of advocating energy conservation, emission reduction and ecological greenness in today's world, thermal insulation materials are changing from industrial thermal insulation to architectural thermal insulation. The country is vigorously advocating low-carbon energy-saving industries and energy-saving energy industries, so we pay more attention to the research, development, promotion and application of building thermal insulation coatings. [0004] Heat insulation coating is a coating that can play a heat insulation effect on the surface of a building. It can be divided into transparent heat insulation coatings and non-transparent heat insulation coatings according to different application occasions;...
