Problems solved by technology

For example, hollow blocks need to be sintered, which consumes a lot of energy and pollutes the environment; gypsum board has poor waterproof performance and low fire limit; polystyrene foam board has low fire limit and will emit polystyrene poisonous gas when it is burned; Large medium damage; magnesium chloride cement plant fiber board has high early strength, insufficient later strength, poor fire resistance, large deformation, easy to reverse halogen, and large residual chloride ion; autoclaved aerated concrete board is easy to separate from the decorative layer, and the output is low enough to meet the market , Fragile during handling, low compressive and crushing strength, poor hanging force and no nail bite, affecting secondary decoration

Abstract

The invention relates to a foam concrete light compound wall board and a preparation method thereof. The wall board comprises upper and lower surface layers and a middle layer filled between the upper and lower surface layers; the upper and lower surface layers are calcium silicate boards and the middle layer is a foam concrete layer; the thickness of the compound wall board is 60-112 mm and the thickness of the calcium silicate boards is 15-16 mm; and the thickness of the foam concrete layer is 30-80 mm. Compared with the prior art, the recycling way of waste slurry is expanded and the damage of the waste slurry to the environment is reduced; the foam concrete light compound wall board has the advantages of light weight, heat preservation and heat insulation, sound insulation and fireproof performance, low elasticity and vibration absorption, waterproof and damp-proof performance, environmental friendliness and energy saving and the like; and the construction is convenient and the civilized, sanitary and efficient construction can be realized.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a foam concrete lightweight composite wallboard and a preparation method thereof. Background technique [0002] With the development of social economy and technology, the society puts forward more stringent requirements for energy conservation and environmental protection in the construction field, which promotes the continuous improvement of building energy conservation and environmental protection technologies. The traditional non-load-bearing wall materials, which use clay as the main raw material and are produced by sintering process, have been gradually eliminated due to defects such as heavy weight, high production energy consumption, and occupation of cultivated land. At present, it is replaced by various light wall panels, and has been widely used in the inner and outer walls of frame structures, light steel structures and prefabricated houses and o...
