High-strength and high-toughness jet support material and preparation method thereof
The invention discloses a high-strength and high-toughness jet support material and a preparation method thereof, and relates to the technical field of jet support materials. 40 to 60 parts of sand; 20 to 30 parts of stone powder; 1.9 to 2.5 parts of hybrid anti-cracking fiber; 10 to 18 parts of silica fume; 2-4 parts of active volcanic ash; 8.5 to 10.5 parts of rubber particles; 2 to 4 parts of redispersible latex powder; 0.5 to 0.7 part of calcium formate; 0.8 to 1.2 parts of a water reducing agent; and 0.3 to 0.5 part of a coupling agent. The jet supporting material is jet mortar which can be used for mining and reinforcement and repair of tunnels, bridges, roads and mountains, has the effects of high-strength toughness supporting, fire prevention, flame retardance, gas leakage blocking, leakage prevention and the like, greatly improves the strength and crack resistance toughness of the supporting material in the front and later periods through optimization and improvement of the formula, and is suitable for large-scale popularization and application. Therefore, the service life and safety of the support material are improved, and the application scene and environment of the material are widened.
本发明公开了一种高强高韧喷射支护材料及其制备方法，涉及喷射支护材料技术领域，该种喷射支护材料包括水泥20～30份；砂子40～60份；石粉20～30份；混杂抗裂纤维1.9～2.5份；硅灰10～18份；活性火山灰2～4份；橡胶颗粒8.5～10.5份；可再分散性乳胶粉2～4份；甲酸钙0.5～0.7份；减水剂0.8～1.2份；偶联剂0.3～0.5份。本发明的喷射支护材料是一种可用于采矿和隧道、桥梁道路以及山体加固和修复的喷射砂浆，具有高强度韧性支护、防火阻燃、封堵气体泄露、防渗漏等作用，通过对配方的优化改进，大大提升了支护材料前后期的强度及抗裂韧性，以此提高了支护材料使用寿命和安全性，拓宽了材料的应用场景和环境。
