Abstract

The invention discloses a polyurethane foam heat insulation and decoration integrated board and a preparation method thereof, and belongs to the technical field of building materials. The polyurethane foam heat insulation and decoration integrated board is obtained through a reaction among modified basalt fibers, modified SiO2 aerogel and a polyurethane composite. The modified basalt fibers are added to the polyurethane material; excellent fireproofing performance, high-temperature resistance, stable mechanical properties at a high temperature, water resistance, acid resistance and normal-temperature alkaline resistance of the modified basalt fibers are utilized; the modified basalt fibers can serve as reinforcements to improve the toughness and strength of the polyurethane composite board, and can also enable the polyurethane composite board to serve as a heat-insulating building material in severe weather conditions. The modified SiO2 aerogel with excellent heat insulation properties can serve as a filler. The polyurethane foam heat insulation and decoration integrated board has excellent mechanical properties, high-temperature resistance and flame retardancy, and can maintain thermal stability at a high temperature.

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 polyurethane foam 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: Compare...
