Multilayer insulation plate

Abstract

The invention discloses a multilayer insulation plate which comprises a decoration surface layer located on the outermost layer. A polyurethane foam plate is arranged on the lower portion of the decoration surface layer. The upper layer of an inorganic insulation layer is connected with the lower layer of the polyurethane foam plate, and an aluminum foil plate is arranged between the polyurethane foam plate and the inorganic insulation plate. The upper layer of a vacuum layer is connected with the lower layer of the inorganic insulation layer, and the upper layer of a soundproof insulation layer is connected with the lower layer of the vacuum layer. The bottom layer of the insulation layer is provided with a cement plate base layer. The multilayer insulation plate has a fireproof effect, a very high insulation effect and a strong soundproof effect, meanwhile, it can be ensured that the multilayer insulation plate can be stuck to an outer wall while the mass is reduced, and the possibility of disengagement is lowered.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a multilayer insulation board. Background technique [0002] Insulation boards are commonly used materials in the construction industry. Installing insulation boards on the exterior walls of buildings can effectively insulate the building itself. Generally, the insulation materials for exterior walls of building materials only use organic or inorganic insulation boards. Organic insulation boards It is mainly made of polystyrene, which is an excellent thermal insulation material. It forms a honeycomb structure through extrusion, which can effectively prevent heat conduction. For the existing insulation board, due to the limitation of material selection, it has obvious deficiencies in corrosion resistance and fire prevention. At the same time, the existing insulation board itself has a relatively large weight, and there are many inconveniences in transportation and installation. ...

Problems solved by technology

For the existing insulation board, due to the limitation of material selection, it has obvious deficiencies in corrosion resistance and fire prevention. At the same time, the existing insulation board itself has a relatively large weight, and there are many inconveniences in transportation and installation. At the same time, the insulation board does not have sound insulation effect, so the noise outside the building has a greater impact on the inside of the building
