Aerogel composite insulation board

Abstract

The invention discloses an aerogel composite insulation board which comprises a panel, a bottom board, an edge sealing board and an insulation core board. The panel and the bottom board are fixedly attached to the upper surface and the lower surface of the insulation core board respectively; the edge sealing board is arranged between the panel and the bottom board, the edge sealing board is arranged on the outer side of the periphery of the insulation core board in a wrapping mode, and the edge sealing board is bonded to the panel, the bottom board and the insulation core board; the insulation core board comprises a honeycomb structural body, and honeycomb pores in the honeycomb structural body are filled with aerogel particles or aerogel powder. The aerogel composite insulation board provides a novel building insulation board and is good in insulating effect, little in material consumption, capable of being widely applied to insulation of outer walls of high-rise buildings and capable of being applicable to different occasions by adopting different bottom board and panel materials according to different conditions, the cost is reduced, and the application range of the aerogel composite insulation board is wide.

Description

technical field [0001] The invention relates to the technical field of thermal insulation building materials, in particular to an airgel composite thermal insulation board. Background technique [0002] At present, for building exterior wall insulation, inorganic insulation materials must be used for high-rise buildings, so most high-rise buildings use insulation mortar for insulation. Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is used to construct the insulation layer of the building surface a building material. Insulation mortar has the following disadvantages: high density: the weight of the insulation layer will easily bring difficulties to the construction, and increase the load-bearing burden of the building skeleton; high thermal conductivity: meet the national energy-saving standard, thick thickness; high hy...

AI Technical Summary

Problems solved by technology

Insulation mortar has the following disadvantages: high density: the weight of the insulation layer will easily bring difficulties to the construction, and increase the load-bearing burden of the building skeleton; high thermal conductivity: meet the national energy-saving standard, and the thickness is relatively thick; high hygroscopicity: it is easy to cause the weight to exceed the standard , falling off; Affected by construction factors, the strength changes greatly

Moreover, the existing composite thermal insulation boards are mainly made of internal thermal insulation boards and external composite materials, wherein the internal thermal insulation panels are generally made of conventional thermal insulation materials (such as foamed plastics), glass fibers or / and airgel and other materials. , the disadvantage is that the heat insulation effect is not ideal, and the scope of use is relatively narrow
