Drying agent and preparation method thereof
The invention relates to a drying agent and a preparation method thereof. The drying agent comprises the following raw materials in parts by weight: 70-90 parts of alkaline residues, 5-15 parts of aluminum oxide and 5-15 parts of an aggregate forming agent. The aggregate forming agent comprises the following raw materials in parts by weight: 15-25 parts of alkaline residues, 35-45 parts of steel slag, 3-6 parts of a waste gypsum mold, 30-35 parts of a cementing material and 0-1.5 parts of an additive. Five indexes, including unit adsorption capacity, unit adsorption speed, adsorption capacityand speed after activation, physicochemical indexes and dust quantity, of the drying agent are superior to existing standards; and the performance of the drying agent is higher than the performance ofsimilar products sold in the market and reaches a high level. The preparation method is easy to control in process, simple and convenient to implement, and beneficial to large-scale production.
