Abstract

The invention provides a super heat insulation aerogel sandwich composite wall plate with a decorative face and a preparation method of the super heat insulation aerogel sandwich composite wall plate. The super heat insulation aerogel sandwich composite wall plate comprises an internal high-strength inorganic plate, high-strength material separation plate components, an aerogel heat insulation core material, an external high-strength inorganic plate and a facing layer from inside to outside. The preparation method of the super heat insulation aerogel sandwich composite wall plate comprises the following steps that (1) cavity preparation is conducted, specifically, molds are placed on the two sides, the high-strength material separation plate components and pre-buried parts are placed in the molds to form a cavity; (2) material distribution is conducted, specifically, an internal high-strength inorganic plate wet material, the aerogel heat insulation core material and an external high-strength inorganic plate wet material are added in the cavity in the step (1); (3) the forming technique is conducted; (4) mold removing is conducted, specifically, after the strength of the high-strength inorganic plates is formed, and mold removing is conducted; and (5) the facing layer is manufactured on the surface of the external high-strength inorganic plate. The super heat insulation aerogel sandwich composite wall plate with the decorative face is small in weight, low in heat conductivity coefficient, simple in preparation technique, suitable for factory assembly line production and suitable for the field of outer walls, curtain walls, indoor separation walls and the like of heat-preservation fireproof and decoration integration.

Description

technical field [0001] The invention relates to a building material and a preparation method thereof, in particular to a super heat-insulating airgel sandwich composite wallboard with a decorative surface and a preparation method thereof. Background technique [0002] Building energy conservation is of great significance to the sustainable development of human beings. The thermal insulation performance of the wall is an important index to measure the energy-saving effect of buildings. At present, the wall insulation method is mainly to paste the insulation layer outside the wall. Commonly used external wall insulation materials include foamed polyurethane, expanded polystyrene, and rock wool. Although they have excellent thermal insulation properties, foamed polyurethane and expanded polystyrene It is flammable in case of fire, produces suffocating smoke, and forms a dripping fire; rock wool is difficult to construct and fails to absorb water. [0003] High-rise / super high...
