Vacuum foam glass thermal-insulation plate

Abstract

The invention discloses a vacuum foam glass thermal-insulation plate. The vacuum foam glass thermal-insulation plate comprises a glass layer, a decoration layer, a vacuum layer and a foam layer; the glass layer is arranged on the outmost layer and is surrounded by the decoration layer; the vacuum layer is arranged in the decoration layer and is surrounded by the decoration layer; the foam layer is arranged in the vacuum layer and is surrounded by the vacuum layer. Compared with a traditional thermal-insulation plate, the vacuum foam glass thermal-insulation plate has the beneficial effects that the phenomena of expanding and shrinkage deformation, aging, cracking, damage and the like of a wall material can be effectively avoided, the service life of the wall can be greatly prolonged, the foam layer is adopted to perform thermal insulation, the weight of the thermal insulation layer of the outer wall is reduced, the practical effect of saving energy resources is achieved, and the vacuum layer can effectively insulate sounds.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a vacuum foam glass thermal insulation board. Background technique [0002] Insulation board is a rigid foam board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, mixed with heat and injected with a catalyst, and then extruded and formed. Its scientific name is heat insulation Using extruded polystyrene foam, the polyurethane insulation board has moisture-proof and waterproof properties. The closed-cell rate of rigid polyurethane is above 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not Seepage. Airgel insulation board, also known as airgel blanket, has a thermal conductivity of 0.018W / (m·K) at room temperature, is fire-resistant and hydrophobic, flame-retardant and high-temperature resistant. It has excellent heat insulation performance. Under the sam...

AI Technical Summary

Problems solved by technology

It has excellent heat insulation performance. Under the same heat preservation requirements, it can reduce the thickness of the building's outer protective structure, thereby increasing the indoor use area. The environmental protection performance is poor, and it is easier to pollute the environment and may cause waste.
