Abstract

The invention belongs to the technical field of building wall heat-insulation materials and particularly relates to a preparation method of a dampproof and composite foaming cement board. A moisture insulation effect is played after frankincense is wrapped with calcium carbide powder, the calcium carbide powder encounters water to react and produce gas after frankincense is dissolved in water, uniform air bubbles are formed in a foaming board and play a foaming effect, lime milk and rice straw ash are fermented under the effect of microbes to obtain high-viscosity reinforcement slurry, hydraulic oil reacts with the reinforcement slurry under the effect of the microbes, and the number of hydrophobic ester groups in the reinforcement slurry is increased. Therefore, the foaming board prepared by using the reinforcement slurry as a raw material has high bonding strength, strong hydrophobicity and a dampproof effect and is not easily powdered, the strength of the foaming board is also obviously improved by using basalt fiber, and the preparation method has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and in particular relates to a preparation method of a moisture-proof composite foamed cement board. Background technique [0002] The largest energy consumer in a building is the external envelope. Due to the difference in thermal insulation performance of the external enclosure structure, the energy consumption of indoor heating or cooling increases. In building energy-saving technology, the most direct way is to reduce the heat loss of the external enclosure structure, that is, to strengthen the application and development of thermal insulation technology of the enclosure structure to reduce the heat loss of buildings. The use of external wall thermal insulation measures can not only reduce loss, improve energy utilization, but also effectively improve the comfort of living in buildings and obtain extensive economic benefits. [0003] Composite foamed ...
