Abstract

The invention discloses a basalt fiber thermal insulation and decoration integrated board and a preparation method thereof, belonging to the technical field of building materials. The invention uses carbon fiber and basalt fiber as skeleton structure materials, and modifies SiO 2 Aerogel is a thermal insulation functional material, combined with inorganic fillers, adhesives and additives to form a basalt fiber thermal insulation and decoration integrated board. The basalt fiber thermal insulation and decoration integrated board of the present invention can be used below 650°C, and its thermal conductivity is about 0.02W / (m·K), which is three to five times that of traditional inorganic thermal insulation materials, and can greatly improve the thermal insulation effect and resistance to High temperature thermal insulation.

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. It has the advantages of stable quality batches, increased production capacity, and no impact on the construction environment. Compared with ordinary fluorocarbon paint board, real stone paint, blister paint and other surface materials, the thermal insulation and decoration integrated board has a long service life, good decorative effect, and environmental protection; compared with wood and PVC decorative materials, it has fireproof and waterproof properties Advantages: Compared wit...
