Novel high-strength low-volume-weight heat preservation fireproof decoration integration plate and preparation method thereof

The invention relates to a novel high-strength low-volume-weight heat preservation fireproof decoration integration plate. The technical scheme includes that the integration plate is composed of a heat preservation layer, a fireproof layer which is coated on the outer surface of the heat preservation layer, a strengthening layer and decorative surface layer. The heat preservation layer is composed of polyurethane foaming plate double-faced composite cement alkali-resistant glass fabric. According to the plate and the preparation method, the strength is high, the heat preservation performance is high, the volume weight of the integration plate is less than 8kg/m2, compared with the volume weight of a conventional integration plate, the volume weight of the integration plate is reduced by 4-6kgm2, fireproof interface agent processing is performed on six surfaces of a core material, compared with existing products, the plate improves the fireproof performance substantially, and fire is prevented from spreading a
