Hydrophobic magnesium oxysulfate cement foam light material
The invention provides a hydrophobic magnesium oxysulfate cement foam light material. The hydrophobic magnesium oxysulfate cement foam light material is prepared from the following components in parts by weight: 1 part of light calcined magnesia powder, 0.75 to 1.20 parts of a magnesium sulfate solution, 0.012 to 0.022 part of a water repellent, 0.30 to 0.75 part of construction waste powder, 0.01 to 0.022 part of a reinforced modifier, 0.008 to 0.021 part of a foam stabilizer, 0.06 to 0.11 part of expanded perlite particles, 0.04 to 0.15 part of foaming agent foam, 0.10 to 0.21 part of palm fibers and 0.007 to 0.011 part of chopped fibers. The preparation method comprises the following steps: respectively adding the magnesium sulfate solution with certain concentration, the water repellent, the reinforced modifier and the chopped fibers into a stirrer, uniformly stirring, adding the light calcined magnesia powder and the construction waste powder, uniformly stirring, adding the expanded perlite particles and the palm fibers, uniformly stirring, adding the foam stabilizer and the foaming agent, uniformly stirring, pouring, maintaining, and demolding to obtain a finished product. And performing secondary maintenance and the like. The hydrophobic magnesium oxysulfate cement foam light material has the advantages of light weight, high strength, fire resistance, heat insulation, water resistance, hydrophobicity, low water absorption rate, low heat conductivity coefficient and excellent durability.
