External wall fireproof heat preservation plate

Abstract

The invention relates to an external wall fireproof heat preservation plate, which consists of a fiberglass gridding cloth and magnesia cement composite reinforced layer, a silicate cotton plate heat preservation layer and reinforcement isolation layers, and is characterized in that the fiberglass gridding cloth and magnesia cement composite reinforced layer is arranged outside the external wall fireproof heat preservation plate, and the silicate cotton plate heat preservation layer is filled inside the external wall fireproof heat preservation plate; and the reinforcement isolation layers are longitudinally and transversely staggered and uniformly distributed in the silicate cotton plate heat preservation layer. The reinforcement isolation layers are uniformly arranged or longitudinally and transversely staggered and uniformly arranged to form three forms of triangular uniform arrangement. The external wall fireproof heat preservation plates of different specifications, sizes and shapes can be manufactured by disposable template filling according to a requirement of a building; industrial production of building materials can be realized; the construction speed is greatly increased; the problems of short service life and low fireproof performance of the conventional external wall heat preservation material are solved; the production cost of the external heat preservation wall plate is greatly reduced; the external wall fireproof heat preservation plate is convenient to construct; and quality can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an exterior wall fire-proof and heat-insulating board that can be widely used in industrial and civil buildings. Background technique [0002] At present, the external wall insulation technology in the field of construction in China is not very perfect. Most of them use the external styrene board system such as pasting benzene board, phenolic resin board, extruded board, cement and polystyrene particle board on the outside of the wall to solve the problem. The external wall insulation is not fireproof, produces poisonous gas when burned, is easy to melt, has poor strength, and has short service life and other defects. There is also the use of light steel skeleton insulation system or polyurethane foam technology. Although the light steel skeleton insulation system solves the above-mentioned defects, due to the poor bonding strength between the cement foam m...

Problems solved by technology

[0002] At present, the external wall insulation technology in the field of construction in China is not very perfect. Most of them use the external styrene board system such as pasting benzene board, phenolic resin board, extruded board, cement and polystyrene particle board on the outside of the wall to solve the problem. The external wall insulation is not fireproof, produces poisonous gas when burning, is easy to melt, poor strength, short service life and other defects

There is also the use of light steel skeleton insulation system or polyurethane foam technology. Although the light steel skeleton insulation system solves the above-mentioned defects, due to the poor bonding strength between the cement foam material and the cement, gaps will appear after the cement dries, so Affect its service life, especially not suitable for use in areas with large temperature differences in the north, and because of its high cost, it is difficult to popularize and use
