Thin-batch powder-removal-free caulking gypsum and preparation process thereof
The invention belongs to the field of caulking gypsum, and particularly discloses thin-batch powder-removal-free caulking gypsum and a preparation process thereof. The caulking gypsum is composed of the following components in percentage by weight: 2-4% of organic silicon powder, 1-3% of calcium hydroxide, 1-3% of redispersible rubber powder, 1-2% of a thickener, 1-2.5% of a retarder, 3% of a colored natural antibacterial material, 1-2% of a preservative, 1% of cross-linked dextran, 0.5% of sodium carboxymethyl cellulose, 0.3-0.7% of a curing agent, 0.1-0.2% of graphene and the balance being gypsum powder. The caulking gypsum disclosed by the invention is fine and smooth in texture, firm in adhesion, diverse in color, corrosion-resistant, durable and not easy to fall off.
本发明属于嵌缝石膏领域，具体公开了一种薄批不脱粉的嵌缝石膏及其制备工艺，所述嵌缝石膏由以下重量百分含量的成分组成：有机硅粉2‑4%，氢氧化钙1‑3%，可再分散胶粉1‑3%，增稠剂1‑2%，缓凝剂1‑2.5%，有色天然抑菌材料3%，防腐剂1‑2%，交联葡聚糖1%，羧甲基纤维素钠0.5%，固化剂0.3‑0.7%，石墨烯0.1‑0.2%，余量为石膏粉。本发明公开的嵌缝石膏质地细腻，粘附牢固，颜色多样，防腐耐用，不易脱粉。
