Background

At present, most of residential buildings in China still adopt the traditional clay brick masonry structure, and the production of clay bricks needs to consume a large amount of land resources and energy, so that environmental pollution gas is generated in the process of producing the clay bricks. In recent years, with sustainable development and building industrialization, new requirements are provided for the material development and construction technology of the wallboard, and the building material is required to be environment-friendly, energy-saving, light in weight, high in strength and convenient and fast in construction speed. Therefore, a batch of novel wallboard materials can be produced, such as gypsum blocks, ceramsite blocks, sintered porous bricks, activated carbon wallboards and the like. The gypsum board is made of building gypsum as a main raw material, is a building material with light weight, high strength, small thickness, convenient processing, good performances of sound insulation, heat insulation, fire prevention and the like, and is one of novel light boards which are mainly developed at present. In addition, the yield of agricultural straws in China is up to 9 hundred million and is huge every year, the development of agricultural mechanization and the change of energy utilization structures of rural commodities greatly reduce the straws which are traditionally used for rural feeds and fuels. But the industrial utilization rate of the straws is not high and is less than 5 percent at present, and a large amount of agricultural straws are everywhere available and are incinerated in the open air, so that the straws become important reasons for air quality and haze generation in China. Therefore, how to accelerate the building speed of the building wall, reduce the cost of building materials and improve the utilization rate of the straw in the building becomes a problem to be solved urgently in the field of wallboards.

In the CN202110838242.8 patent, most of the gypsum boards on the market have some common problems, and after a long period of use, the gypsum boards have phenomena such as natural fracture, nail-stripping, deformation, pulverization, and indirect seam cracking. Meanwhile, the composite gypsum board and the manufacturing method thereof are disclosed, and mainly provide the composite gypsum board which comprises a base gypsum board, wherein the base gypsum board is connected with a reinforcing board, and the reinforcing board is coated with a protective layer. However, the construction method is analyzed to find that: the construction method has more complex working procedures, and the plate cost of the reinforcing plate is a remarkable expense. Therefore, the fireproof and moistureproof wallboard which has the advantages of high construction speed, environment-friendly building material and strong regenerability, has low material cost, is a necessary trend for building material development, and achieves light weight, high strength and is urgent in the field of wallboards.
