Fireproof anti-crack cement guniting plugging support material and preparation method thereof
The invention belongs to the technical field of cement, and discloses a fireproof anti-crack cement guniting plugging support material and a preparation method thereof, the fireproof anti-crack cement guniting plugging support material comprises 30-40 parts by weight of cement, 45-55 parts by weight of sand, 15-20 parts by weight of water, 3-10 parts by weight of corundum, 6-15 parts by weight of an acrylic resin emulsion, and 1.2-3 parts by weight of nano-silica coated glass fiber. The nano-silica coated glass fiber and corundum are used as additives of the cement guniting plugging material, the nano-silica coated glass fiber has better toughness and mechanical strength, the strength of the cement guniting plugging material can be improved, and the fused white corundum and tabular corundum have very strong fire resistance, so that the cement guniting plugging material has good fire resistance. Therefore, the cement guniting plugging material has excellent strength, fire resistance and cracking resistance.
本发明属于水泥技术领域，且公开了一种防火抗裂水泥喷浆封堵支护材料和制备方法，包括30‑40重量份水泥、45‑55重量份砂子、15‑20重量份水、3‑10重量份刚玉、6‑15重量份丙烯酸树脂乳液、1.2‑3重量份纳米二氧化硅包覆玻璃纤维。本发明以纳米二氧化硅包覆玻璃纤维、刚玉作为水泥喷浆封堵材料的添加剂，纳米二氧化硅包覆玻璃纤维具有更好的韧性和力学强度，可以提高水泥喷浆封堵材料的强度，而电熔白刚玉和板状刚玉具有很强的耐火性能，从而使水泥喷浆封堵材料具有优异的强度、耐火防火性能和抗开裂性能。
