Problems solved by technology

At present, the thickening of multi-layer glass fiber mats or ceramic fiber mats, the compounding of glass fiber mats / ceramic fiber mats with aluminum foil, aluminized film, and the bonding of thermal insulation felts (boards) and walls all use traditional glue. Adhesives are used for bonding, and these adhesives have no thermal insulation effect. Although the thickness of the adhesive is relatively thin, it will more or less affect the thermal insulation effect of the entire thermal insulation system.

Abstract

The invention relates to a mesoporous material composite thermal insulation adhesive, which further reduces the heat conductivity coefficient of the whole thermal insulation system and improves the thermal insulation effect in the thickening of a plurality of layers of glass fiber felts or ceramic fiber felts, the compounding of the glass fiber felts / ceramic fiber felts, aluminum foils and aluminized films and the bonding of the thermal insulation felts (plates) and a wall body.

Description

technical field [0001] The invention belongs to the field of material field, in particular to a mesoporous material composite thermal insulation adhesive and a preparation method thereof. Background technique [0002] With the development of society, energy consumption is increasing day by day. In response to the national call for energy conservation, various types of thermal insulation materials emerge in an endless stream. At present, the thickening of multi-layer glass fiber mat or ceramic fiber mat, the compounding of glass fiber mat / ceramic fiber mat and aluminum foil, aluminized film, and the bonding of thermal insulation felt (board) and wall are all traditional adhesives. Adhesives are used for bonding, and these types of adhesives do not have the effect of thermal insulation. Although the thickness of the adhesive is relatively thin, it will more or less have a certain impact on the thermal insulation effect of the entire thermal insulation system. SUMMARY OF THE ...
