Bombax ceiba aerogel thermal insulation board

Abstract

The invention discloses a bombax ceiba aerogel thermal insulation board. The bombax ceiba aerogel thermal insulation board comprises a panel (1), a bottom board (3) and a thermal insulation core board(2); the panel (1) and the bottom board (3) are respectively fixed and fitted on the upper surface and the lower surface of the thermal insulation core board (2), the panel (1) and the bottom board (3) are made of an inorganic cementitious material; the thermal insulation core board (2) is prepared by taking a bombax ceiba aerogel as the main material, doping a bombax ceiba fire resistant fiber and the inorganic cementitious material, stirring, foaming and wrapping, the bombax ceiba aerogel is a SiO2 aerogel prepared by taking bombax ceiba as the raw material through a cracking process. The ultralight density and the ultralow heat conductivity coefficient of the bombax ceiba aerogel and the high strength and flame retardant property of the inorganic cementitious material are used, so thatthe bombax ceiba aerogel thermal insulation board is environmentally friendly in comparison with the conventional SiO2 aerogel thermal insulation product, the cost is low, the production process is simple, the strength is high, the density is low, the thermal insulation effect is better, and the bombax ceiba aerogel thermal insulation board belongs to a light green environmentally friendly product.

Description

technical field [0001] The invention relates to a light-weight thermal insulation material for building, in particular to a kapok airgel thermal insulation board with kapok airgel as the main material. 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 aggregates, cement as cementitious material, mixed with some modified additives, and mixed by mixing. It is used to construct a building surface insulation layer. kind of building material. Insulation mortar has the following disadvantages: high density, high thermal conductivity, high hygroscopicity, and large changes in strength affected by construction factors. Moreover, the existing composite thermal insulation boards are mainly prepared from internal thermal insul...

Insulation mortar has the following disadvantages: high density, high thermal conductivity, high moisture absorption, and large changes in strength affected by construction factors

It is light in weight and good in thermal insulation and sound insulation performance, but their conventional production methods have high requirements on equipment, complicated process, supercritical drying, large energy consumption, and high operation risk, which lead to a significant increase in the cost of airgel and low cost performance. Limiting its promotion in the construction industry
