Composite heat insulation board

Abstract

The invention discloses a composite heat insulation board. The composite heat insulation board comprises a first heat insulation board layer and a second heat insulation board layer which are arrangedoppositely. A fireproof layer is arranged between the first heat insulation board layer and the second heat insulation board layer. The fireproof layer is a latticed frame formed by a double-layer aluminum wire mesh. Half of a grid is internally provided with phenolic foam. The first heat insulation board layer and the second heat insulation board layer are connected together through the other half of the grid. T-shaped grooves are formed in the lower portion of the second heat insulation board layer. The two sides of the fireproof layer are provided with protruding blocks and grooves, wherein the protruding blocks correspond to the grooves. The middle of the composite heat insulation board is provided with the latticed fireproof layer, connection between the first heat insulation board layer and the second heat insulation board layer is not affected, the fireproof, heat insulation and sound isolation effects are good, and the service life is long; and the T-shaped grooves are formedin the lower portion of the second heat insulation board layer, so that the composite heat insulation board and a base layer wall are closely combined and do not slide off, and construction is safe, fast and convenient.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a composite thermal insulation board. Background technique [0002] The current insulation board is a foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, heated and mixed while injecting a catalyst, and then extruded or foamed. It has excellent thermal insulation performance, and can reduce the thickness of the building's outer envelope under the same thermal insulation requirements, thereby increasing the indoor usable area. The existing thermal insulation boards have good thermal insulation effects, but the fireproof and sound insulation effects are slightly poor; and at present, when pouring wall columns, the thermal insulation boards are prone to loosening, and the phenomenon of "hollowing" between the insulation boards and the concrete is easy to appear, which is not reliable, and ...

AI Technical Summary

Problems solved by technology

The existing thermal insulation board has good thermal insulation effect, but the effect of fire prevention and sound insulation is slightly poor; and at present, when pouring wall columns, the thermal insulation board is prone to loosening, and the phenomenon of "hollowing" between the insulation board and the concrete is easy to appear, which is not reliable, and it is not reliable during the pouring process. The middle insulation board is also easy to detach, which has unsafe factors and needs to be improved
