Lightweight gypsum-based fireproof coating and preparation method thereof
The invention belongs to the field of refractory materials, particularly relates to the field of C04B28, and more particularly relates to a lightweight gypsum-based fireproof coating and a preparation method thereof. The fireproof coating is prepared from the following raw materials in parts by mass: 58 to 62 parts of gypsum powder, 8 to 10 parts of sepiolite, 4 to 6 parts of mica sheet, 20 to 25 parts of perlite, 0.1 to 0.5 part of thixotropic lubricant, 0.3 to 0.8 part of anti-crack fiber, 0.8 to 1.2 parts of adhesive and 0.1 to 0.3 part of retarder. The obtained gypsum-based fireproof coating has excellent bonding performance, the bonding strength is not smaller than 0.06 MPa, the dry density and the stacking density are low, in addition, the drying time, the crack resistance test, the exposure heat resistance test, the moisture resistance test and the freezing resistance test detection items all conform to the national standard, and the gypsum-based fireproof coating has an excellent actual use effect.
本发明属于耐火材料领域，尤其涉及C04B28领域，更具体的涉及一种轻质石膏基防火涂料及其制备方法。防火涂料的制备原料按照质量份数计包括：58‑62份石膏粉，8‑10份海泡石，4‑6份云母片，20‑25份珍珠岩，0.1‑0.5份触变润滑剂，0.3‑0.8份抗裂纤维，0.8‑1.2份粘接剂，0.1‑0.3份缓凝剂。本发明所得石膏基防火涂料有优异的粘接性能，粘接强度不小于0.06MPa，且有较低的干密度和堆积密度，另外干燥时间，抗裂试验，耐曝热性试验，耐湿试验，耐冻试验检测项目全部符合国标，有优异的实际使用效果。
