Embodiment 1
[0012] An environmentally friendly waterproof gypsum block is made from β hemihydrate gypsum, water reducing agent, inorganic materials and composite waterproofing agent after stirring and pouring. Among them, the inorganic material is 10% of the weight of the gypsum, the water reducing agent is 0.5% of the weight of the gypsum, the composite waterproofing agent is 0.8% of the weight of the gypsum, and the water is 62% of the weight of the gypsum. The weight of each component of the inorganic material is: diatomite 25; alunite powder 15; 180-220 mesh can be selected or mixed. The weight of each component of the composite waterproofing agent is: ethyl silicate 0.2; aluminum stearate 0.15; sodium tetraborate 0.1; water 8.
