Abstract

The invention discloses an external wall thermal insulation and decoration integrated composite board and a preparation method thereof. The composite board includes a surface decoration layer, an intermediate bonding layer and a thermal insulation layer. The surface decoration layer is made of carbonized cementitious material, carbonized reinforcing agent and water; the middle bonding layer is made of steel slag powder, hydraulic cementitious material, silicon Ash, water reducing agent, quartz sand and water; the thermal insulation layer is made of carbonized cementitious material, hydraulic cementitious material, silica fume, water reducing agent, water and foaming agent or polystyrene foam particles. The main composition of each layer of the composite board is calcium carbonate, the physical properties between the layers are close, the combination is firm, it is not easy to peel off, and the degree of integration is high; the thickness of the surface decoration layer is highly controllable, the density is low, and the structure of the middle adhesive layer is high. , low water absorption, and not easy to age; the composite board is combined with CO 2 Carbonization at room temperature can quickly form strength, high production efficiency, low energy consumption, and at the same time, a large amount of industrial waste is used, which has the advantages of carbon sequestration and environmental protection, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an exterior wall thermal insulation and decoration integrated composite board and a preparation method thereof. Background technique [0002] my country's building energy consumption is astonishing, building energy consumption accounts for 47% of the country's total energy consumption, a large part of which is used for building heating. Among them, one of the effective means to reduce the energy consumption of buildings is the external wall insulation technology. External wall insulation minimizes building energy consumption by blocking cold outside air from entering the room while preventing hot indoor air from diffusing outward. Therefore, the development of new materials and technologies for external wall insulation is of great significance to reduce building energy consumption. [0003] The external wall thermal insulation integrated system is composed of thermal...
