Abstract

The invention discloses a polyurethane foam thermal insulation and decoration integrated board and a preparation method thereof, belonging to the technical field of building materials. The present invention adopts modified basalt fiber, modified SiO 2 Airgel and polyurethane composite materials are reacted to prepare a polyurethane foam insulation and decoration integrated board. The invention adds modified basalt fiber to the polyurethane material, utilizes the excellent fireproof performance and high temperature resistance of basalt fiber, and has stable mechanical properties, water resistance, acid resistance and alkali resistance at room temperature, not only as a reinforcement, but also can improve The toughness and strength of the polyurethane composite board can also improve the application of the polyurethane composite board as a thermal insulation building material in severe weather environments. The present invention also uses modified SiO 2 Airgel is used as a filler, which has excellent heat-proof and heat-insulating properties. The polyurethane foam thermal insulation and decoration integrated board of the present invention has excellent mechanical properties, high temperature resistance and flame retardancy, and can maintain thermal stability at high temperatures.

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.
