The invention with the Chinese patent application number 201610090524.3 discloses a cement-based foamed lightweight composite material and its preparation method. Regulation, through the use of modified starch foam stabilizer and graphene oxide nano-materials to achieve effective regulation of the pore structure and cement hydration products and structure, so that the pore structure formed has fine particle size, uniform distribution, and regular shape of cement hydration products , arranged in an orderly manner, so that the cement-based foam composite material has a cross-linked network structure, so as to improve the strength and toughness of the cement-based lightweight composite material, but the raw materials used need to be pre-treated, and the operation process is complicated, only recorded The density in strength is 0.6~0.7g / cm 3 , the compressive strength is greater than 2.5MPa, and the wear resistance, weather resistance, high temperature resistance, heat insulation, sound insulation, waterproof and impermeability have not been better improved, and need to be improved
The invention of Chinese patent application number 201610258377.6 discloses a lightweight partition wall board with loofah fibers added. In this application, a large amount of chemical additives and conventional raw materials are used. The raw materials are expensive and complicated. The prepared wall board has good Excellent heat insulation effect, not prone to gaps, moisture absorption, and bubbling characteristics, which improves the quality of the partition wall, but the water absorption rate still reaches 21.4%, and the compressive strength is 5.5MPa, and there is still room for further improvement
