Problems solved by technology

Foamed cement board is a kind of external wall insulation material that is gradually emerging at present. It is not easy to age, has the same life as the building, light bulk density, low thermal conductivity, and the fire resistance limit is more than 3 hours. Poisonous gas and other advantages, but the disadvantages of the foamed cement version are also obvious, that is, poor mechanical properties, low strength, high brittleness, very easy to break and damage, which brings great inconvenience to the transportation and construction process

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation and energy-saving material and a cement board thereof. Background technique [0002] The implementation of building energy-saving policies has promoted the development of wall insulation materials. Organic foam plastic insulation materials such as polystyrene and polyurethane are widely used in wall insulation. However, such organic foam plastic insulation materials are extremely flammable. When burning, the fire spreads rapidly and is accompanied by a large amount of poisonous gas and smoke. Serious difficulties in work, resulting in casualties and property damage. At the same time, this type of insulation material also has disadvantages such as easy aging and poor dimensional stability. Compared with organic foam insulation materials, inorganic insulation materials have the advantages of good fire resistance, small deformation coefficient, stro...
