Graphene eps fireproof insulation board and preparation method thereof

Abstract

The invention relates to the field of a fireproof heat-insulating material and especially relates to a graphene EPS fireproof heat-insulating plate and a preparation method thereof. The method for preparing the graphene EPS fireproof heat-insulating plate comprises the following steps: physically foaming a binding material and then mixing with graphene EPS, rolling and forming. The volume ratio of binding material to graphene EPS is 100:(65-85). The fireproof heat-insulating plate has excellent heat-insulating effect, excellent fireproof property and capability of promoting the safety of the heat-insulating plate.

Description

technical field [0001] The invention relates to the field of fireproof and thermal insulation materials, and in particular to a graphene EPS fireproof thermal insulation board and a preparation method thereof. Background technique [0002] Existing A-level insulation materials such as rock wool insulation boards are not environmentally friendly, have poor weather resistance, are difficult to construct, and are easy to absorb water and fall off. The high thermal conductivity of foamed cement insulation boards makes it difficult to adapt to some buildings that require high energy conservation in the country. Chlorine oxygen is often used for homogeneous boards. Magnesium cement, that is, the production of ordinary EPS, has the disadvantage of being easily deformed by anti-halogen and anti-alkali, and has many defects. Foam glass and foam ceramics are also materials with high thermal conductivity. Class B materials such as molded EPS (EPS extruded board, phenolic board, etc.) a...

Problems solved by technology

[0002] Existing A-level insulation materials such as rock wool insulation boards are not environmentally friendly, have poor weather resistance, are difficult to construct, and are easy to absorb water and fall off. The high thermal conductivity of foamed cement insulation boards makes it difficult to adapt to some buildings that require high energy conservation in the country. Chlorine oxygen is often used for homogeneous boards. Magnesium cement, that is, the production of ordinary EPS, has the disadvantage of being easily deformed by anti-halogen and anti-alkali, and has many defects. Foam glass and foam ceramics are also materials with high thermal conductivity. Class B materials such as molded EPS (EPS extruded board, phenolic board, etc.) are all organic materials. Although the thermal insulation effect is superior, they cannot achieve the proper fire resistance, and are prone to fire, posing serious safety hazards.
