Abstract

The invention relates to the technical field of building structure heat preservation, in particular to an aerogel heat preservation and insulation system and a construction process thereof, and aims to solve the technical problems that an existing building structure heat preservation and insulation system is thick and heavy in structure, a plastering layer is prone to hollowing, falling and cracking, the construction process is complex, and the labor intensity of operators is high. According to the technical scheme, the aerogel heat preservation and insulation system is formed by sequentiallycoating a water-based multifunctional bottom coating, an aerogel heat preservation and insulation middle coating and an aerogel reflection and insulation surface coating which are specific in component. The construction process of the aerogel heat preservation and insulation system is divided into three major steps of water-based multifunctional bottom coating construction, aerogel heat preservation and insulation middle coating construction and aerogel reflection and heat insulation surface coating construction, each step comprises several substeps, the whole construction process is simple and easy to operate, and the labor intensity of operators can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of thermal insulation of building structures, in particular to an airgel thermal insulation system and a construction process thereof. Background technique [0002] At present, there are many types of thermal insulation systems on walls and other building structures in the market. The more common one is extruded polystyrene board (XPS), which has a bulk density of 29KG / m³ and a thickness of 50-75mm. Cement mortar is plastered with alkali-resistant glass fiber mesh cloth, but it has the following problems: the structure is thick, the plaster layer is easy to hollow, easy to fall off and crack, the construction process is complicated, and the labor intensity of operators is high. Contents of the invention [0003] The invention aims to solve the technical problems of the existing building structure heat preservation and heat insulation system, which are thick and heavy, the plastering layer is easy to be hol...
