Tunnel grouting and water plugging material and preparation method thereof
The invention discloses a geopolymer grouting and water plugging material with high mechanical property, which is prepared from the following raw materials in parts by weight: 10 to 300 parts of cement, 10 to 260 parts of superfine cement, 10 to 260 parts of fine aggregate, 10 to 130 parts of bentonite, 5 to 146 parts of polyurethane, 5 to 60 parts of acrylate polymer, 1 to 10 parts of waterproof agent, 2 to 8 parts of polypropylene fiber and 1 to 4 parts of antioxidant. The grouting and water plugging material for the tunnel is adjusted through a water reducing agent, and the water-binder ratio of the grouting and water plugging material is 0.4. According to the grouting and water plugging material disclosed by the invention, through the synergistic effect of the cement, the superfine cement, the fine aggregate, the bentonite, the polyurethane, the acrylate polymer, the waterproof agent, the polypropylene fiber and the antioxidant, the tensile strength, the toughness and the durability of the material are remarkably enhanced. Wherein the polypropylene fibers form a three-dimensional network structure in the material, so that the tensile strength and the toughness are effectively enhanced.
本发明公开了一种高力学性能的地聚物注浆堵水材料，原料包括如下重量份的原料：水泥10‑300份、超细水泥10‑260份、细集料10‑260份、膨润土10‑130份、聚氨酯5‑146份、丙烯酸酯类聚合物5‑60份、防水剂1‑10份、聚丙烯纤维2‑8份、抗氧化剂1‑4份，隧道注浆堵水材料通过减水剂进行调节，其水胶比为0.4。本申请的注浆堵水材料通过水泥、超细水泥、细集料、膨润土、聚氨酯、丙烯酸酯类聚合物、防水剂、聚丙烯纤维、抗氧化剂的协同作用，显著增强了材料的抗拉强度、韧性和耐久性。其中，聚丙烯纤维在材料内部形成了三维网络结构，有效增强了抗拉强度和韧性。
