Plastering gypsum capable of purifying air and preparation method thereof
The invention discloses plastering gypsum capable of purifying air and a preparation method thereof. The plastering gypsum contains building gypsum and a composite material of calcium alginate and biochar. The method comprises the following steps of: mixing the composite material of calcium alginate and biochar with an optional coupling agent, and then mixing the obtained mixture with AII type anhydrous gypsum to obtain a first mixture; mixing rubber powder, a water-retaining agent and an optional retarder to obtain a second mixture; mixing the first mixture with the second mixture to obtain athird mixture; and mixing the third mixture with the building gypsum and optionally machine-made sand to obtain the plastering gypsum capable of purifying air. The plastering gypsum can effectively adsorb heavy metals and other harmful particles in air and eliminate harm of heavy metal pollution to human bodies.
