Quick-setting high-bonding-strength modified grouting material
The invention discloses a quick-setting high-bonding-strength modified grouting material and relates to the technical field of grouting materials, modified microspheres comprise shells and core materials coated with the shells, the core materials comprise styrene-acrylic emulsion and cement coagulant, the shells are polymethyl methacrylate shells, and the modified microspheres are high-pressure release type microspheres. According to the invention, the cement accelerator and the styrene-acrylic emulsion are wrapped in the microspheres for preparing the modified cement-based single-liquid grouting material, and the cement accelerator and the styrene-acrylic emulsion are not contacted with other components in the slurry during preparation, so that the preparation process of the cement-based grouting material slurry is not influenced; meanwhile, the styrene-acrylic emulsion film can obviously improve the hydrophobic effect of the stone body. The modified cement-based single-liquid grouting material provided by the invention has the advantages of short setting time and high bonding strength, and can solve the problem of poor deformation treatment effect when the existing grouting material is used for tunnels or roadways and the like.
本发明公开了一种快凝高粘接强度的改性注浆材料，涉及注浆材料技术领域，所述改性微球包括壳体及被壳体包覆的核材，所述核材包括苯丙乳液、水泥促凝剂，所述壳体为聚甲基丙烯酸甲酯壳体，所述改性微球为高压释放型微球。本发明将水泥速凝剂和苯丙乳液包裹在微球内部，用于制备改性水泥基单液注浆材料，在制备时水泥速凝剂和苯丙乳液不会与浆液中的其它组分接触，从而不会对水泥基注浆材料浆液的制备工序产生影响，同时苯丙乳液薄膜可显著提高结石体的疏水效果。本发明提供的改性水泥基单液注浆材料具有凝结时间短、粘接强度高的优势，可解决现有的注浆材料用于隧道或巷道等变形治理效果较差的问题。
