Abstract

The invention discloses an aerogel heat preservation fireproof plate with a decorative face and a preparation method of the aerogel heat preservation fireproof plate. The aerogel heat preservation fireproof plate is characterized in that the aerogel heat preservation fireproof plate with the decorative face is composed of an aerogel material, a transitional layer and a facing layer, the aerogel material is composed of a surface hydrophillic layer and an internal hydrophobic layer, and the thickness of the surface hydrophillic layer is 0.1-100 [mu]m. The preparation method comprises the following steps that (1) the aerogel material is modified; (2) the aerogel material in the step (1) is coated with the transitional layer; and (3) the facing layer is manufactured on the transitional layer in the step (2). The aerogel heat preservation fireproof plate with the decorative face has excellent performance such as the low density, the low heat conductivity coefficient, the low water absorption rate, sound insulation and heat-preservation decoration and fireproof integration, the construction work procedures are reduced, the engineering manufacturing cost is reduced, the problem that the construction quality is difficult to control is solved, and the aerogel heat preservation fireproof plate can be widely suitable for the field of outer walls, self-heat preservation wall bodies, floor clapboards and the like of environmental-friendly buildings and super-low-energy-consumption and near zero energy buildings.

Description

technical field [0001] The invention relates to a preparation method of a building thermal insulation and fireproof material, in particular to an airgel thermal insulation and fireproof board with a decorative surface and a preparation method thereof, belonging to the fields of light weight, heat insulation, fireproof, sound insulation materials and the like. Background technique [0002] With the progress of society, problems such as energy crisis and environmental degradation are becoming more and more serious. In 2006, the "Outline of the Eleventh Five-Year Plan for National Economic and Social Development" put forward the concept of "energy saving and emission reduction" for the first time. %, and the binding target of reducing the total discharge of major pollutants by 10%. "Energy saving" promotes "emission reduction". In the total energy consumption of domestic production, building energy consumption accounts for 33%. Building energy conservation is the top priority ...
