Abstract

The invention discloses a basalt fiber thermal insulation decorative integrated plate and a preparation method thereof, belonging to the technical field of building materials. According to the invention, carbon fiber and basalt fiber are taken as framework structural materials, modified SiO2 aerogel is taken as a heat insulation functional material, and inorganic fillers, adhesives and additives are combined to form the basalt fiber heat insulation decorative integrated plate. The basalt fiber thermal insulation decorative integrated plate can be used below 650 DEG C, has a thermal conductivity of about 0.02 W / (mK), is three to five times that of the traditional inorganic thermal insulation material, and can greatly improve the thermal insulation effect and high-temperature resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation material, in particular to a basalt fiber thermal insulation and decoration integrated board and a preparation method thereof. Background technique [0002] Thermal insulation and decoration integrated board is a new type of chemical building material that integrates functions such as decoration, energy saving, fire prevention, waterproof, and environmental protection.
