A kind of airgel composite sound-insulation and heat-insulation partition board and preparation method thereof

Abstract

The invention discloses an aerogel composite sound insulation and heat preservation partition board and a preparation method thereof. The partition wall board comprises: a surface layer and a sound insulation and heat insulation core layer; the surface layer is a hollow closed shell structure, and the sound insulation and heat insulation core layer is provided with Inside the surface layer; the sound insulation and heat preservation core layer includes: an aerogel layer; and tenons and tenon grooves are respectively arranged on the outer surfaces of both sides of the surface layer. The aerogel composite sound insulation and heat insulation partition board of the present invention and the preparation method thereof utilize the excellent light weight, heat insulation and sound insulation properties of the aerogel material to provide a novel lightweight, thermal insulation, sound insulation and environment-friendly partition board and The preparation method has better thermal insulation effect, can reduce the thermal conductivity of foamed cement to less than half, and has high strength, is all inorganic material, has a fire rating of Class A, and has good sound insulation effect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation building materials, in particular to an airgel composite sound-insulation and thermal insulation partition wall board and a preparation method thereof. Background technique [0002] At present, the external wall insulation of buildings requires the use of inorganic insulation materials 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 c...

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
