Silica purification material and preparation method therefor
The invention relates to a silica purification material and a preparation method therefor. The silica purification material is prepared from the following ingredients in percentage by weight: 70-76% of polystyrene particles, 3-9% of silica, 3-9% of magnesia, 4-10% of magnesium chloride and 5-11% of magnesium oxysulfate. The preparation method for the silica purification material comprises the steps: mixing 47-53% of water, 3-9% of silica, 3-9% of magnesia, 4-10% of magnesium chloride and 5-11% of magnesium oxysulfate, so as to form a raw material solution; putting a polystyrene plate in silica purification material production equipment, and enabling the raw material solution to permeate into the polystyrene plate through negative pressure; and baking and curing the raw material solution permeated polystyrene plate through high temperature generated by a baking oven. The silica purification material provided by the invention has the advantages of small coefficient of thermal conductivity, large coefficient of heat accumulation and high safety; and the silica purification material is high in strength, does not absorb water, does not fall off, is easy to construct and is free of surface dust, and the construction cost is equal to that of ordinary polystyrene.
