[0004] 1. The invention with the Chinese patent application number 201610090524.3 discloses a cement-based foamed lightweight composite material and its preparation method. The structure is regulated, and the pore structure, cement hydration products and structure are effectively regulated by using modified starch foam stabilizer and graphene oxide nanomaterials, so that the pore structure formed has a fine particle size and uniform distribution, and the cement hydration products The shape is regular and the arrangement is orderly, so that the cement-based foam composite material has a cross-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. It is recorded that the density in the 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
[0005] 2. The invention of Chinese patent application number 201610258377.6 discloses a lightweight partition wall board with loofah fibers added. In this application, a large number of chemical additives and conventional raw materials are used. The raw materials are expensive and complicated. The prepared wall board, It has a good heat insulation effect, and is not prone to gaps, moisture absorption, and bubbling, which improves the quality of the partition wall. However, the water absorption rate still reaches 21.4%, and the compressive strength is 5.5MPa. There is still room for further improvement
