Abstract

The invention provides a heat insulation building material and a preparation method thereof. The preparation method includes the steps: uniformly mixing in advance bamboo scraps, liquid water glass, chloroprene rubber adhesive and an appropriate amount of water, standing for 10-20 days, and continuously mixing for 1-2 hours every other one or two days during 10-20 days to prepare paste; preparing light calcium carbonate, expanded perlite, lime crystal, sand and lime into powder, adding concrete, gypsum powder and coal ash, and sufficiently and uniformly mixing to prepare powdery dry mixture; sufficiently mixing foaming agents, addition agents, the paste obtained in the step (2) and the dry mixture obtained in the step (3) to prepare mortar; waiting solidification of the mortar in the step (4) at normal temperature to obtain the heat insulation building material. The preparation method effectively reduces dependency on mineral resources, and the material is easily obtained, suitable for large-scale production and manufacturing and remarkable in heat insulation and cooling effect.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a heat-insulating building material and a preparation method thereof. Background technique [0002] Concrete is currently one of the most dominant materials in contemporary construction. Concrete is a composition, which is uniformly solidified by mixing several components with functions and water in a certain proportion. The components with functions mainly include cementitious materials and aggregates. A certain proportion is mixed evenly to prepare mortar, and the mortar is solidified under certain conditions to become artificial stone. [0003] However, there is a common problem that concrete structures cannot be insulated. In the hot summer, after a long time of high-temperature baking, the walls of the building absorb a lot of heat. Although the outdoor temperature drops a lot at night and the outside is very cool, the walls still continue to dissipate heat into the room ...
