Shield waterproof material and preparation method thereof
The invention belongs to the technical field of shield waterproof materials, and provides a shield waterproof material and a preparation process thereof in order to solve the problem that an existing shield is poor in waterproof performance. The shield waterproof material is prepared by mixing the following raw materials in proportion: common concrete, water, an amorphous [alpha]-olefin copolymer, a titanate coupling agent, a polyoxyethylene ether mixture, an efficient polycarboxylic acid water reducer, 19mm polypropylene long fibers, polyisobutene, polystyrene, stearic acid, a waterproof agent, an expanding agent, a stabilizer, a plasticizer and an air entraining agent. Corresponding additives are introduced into the formula, the internal strength, the impact resistance and the corrosion resistance of the material are improved by utilizing the performance of the additive; and the overall stability of the device is realized and the overall performance of the material is improved by integrally improving the formula, increasing the strength and the pressure resistance of the material through the additive and stirring in batches through a prefabrication process.
本发明属于盾构防水材料技术领域，为解决现有盾构防水性能不佳的问题，提供一种盾构防水材料及其制备工艺，由如下原料按比例混合制备而成：普通混凝土、水、非晶态α‑烯烃共聚物、钛酸酯偶联剂、聚氧乙烯醚混合物、高效聚羧酸减水剂、19mm聚丙烯长纤维、聚异丁烯、聚苯乙烯、硬酸脂、防水剂、膨胀剂、稳定剂、增塑剂、加气剂，通过在配方中引入相应添加剂，利用添加剂的性能提高材料内部的强度、抗冲击力度以及耐腐蚀性能；通过在配方中进行整体改进，通过添加剂增加材料自身的强度和抗压能力，并通过预制工艺进行分批次搅拌，实现装置的整体稳定性，提高材料的整体性能。
