Caulking gypsum capable of purifying air and preparation method thereof
The invention discloses caulking gypsum capable of purifying air and a preparation method thereof. The caulking 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, a thixotropic agent and an optional retarder to obtain a second mixture; mixing the first mixture with the second mixture to obtain a third mixture; and mixing the third mixture with the building gypsum to obtain the caulking gypsum capable of purifying air. The caulking gypsum can effectively adsorb heavy metals and other harmful particles in air and eliminate harm of heavy metal pollution to human bodies.
一种能够净化空气的嵌缝石膏及其制备方法。所述嵌缝石膏中含有建筑石膏和海藻酸钙与生物炭的复合材料。所述方法包括：将海藻酸钙与生物炭的复合材料与任选地偶联剂混合，然后与AII型无水石膏混合，得到第一混合料；将胶粉、保水剂、触变剂与任选地缓凝剂混合，得到第二混合料；将所述第一混合料与所述第二混合料混合，得到第三混合料；将所述第三混合料与建筑石膏混合，得到所述能够净化空气的嵌缝石膏。本申请的嵌缝石膏能够有效吸附空气中的重金属及其他有害颗粒，消除重金属污染对人体的危害。
