Abstract

The invention provides a building fireproof and heat insulating hollow plate. An outer face plate and an inner face plate are parallel up and down; a cement tank is arranged on the inner face plate and connected with the inner side of the outer face plate; a heat dissipation device is connected with the cement tank and sequentially penetrates through a supporting face, a fireproof layer and the outer face plate; the heat dissipation device comprises a filling layer stacked and piled through heat dissipation mediums and further comprises a heat conducting plate connected with the cement tank and the filling layer; as for the filling layer in the direction from the cement tank to the outer face plate, the stacking density is sequentially and progressively increased, and the cross cutting area is sequentially and progressively decreased; and the progressive change range of the stacking density is 0.5-2.8 g / cm<3>, and the progressive change range of the cross cutting area is 4-50 cm <2>. According to the building fireproof and heat insulating hollow plate, heat in the hollow late can be discharged and dissipated in time when a fire occurs, the building fireproof and heat insulating hollow plate is not burned in the fire and can be recycled for many times, and the building fireproof and heat insulating hollow plate has the good fireproof, heat insulating, sound insulating functionsand is an excellent building material.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a building fire-proof and heat-insulating hollow board. Background technique [0002] Hollow board, also known as PP hollow board, hollow partition board, Wantong board, corrugated board, double-wall board, generally uses polypropylene and polyethylene as raw materials, has low ignition point, strong thermoplasticity, and is easy to deform in high temperature environment. When exposed to fire, it is easy to burn rapidly. In the prior art, in order to improve the fire resistance of the hollow board, methods of adding flame retardants or making metal hollow boards are generally adopted, but there are still many deficiencies. The flame retardant can only keep the hollow board from burning in a short period of time, and it still cannot inhibit the burning of the hollow board when the fire situation is serious. Although the metal hollow plate can solve the problem of th...
