摘要: 介绍了一种环保交联剂的合成方法,该交联剂无毒且可溶于水,可取代原丙烯酸盐化学灌浆材料常用交联剂甲撑双丙烯酰胺,解决甲撑双丙烯酰胺不易溶解和污染环境等问题。并以此种交联剂为原料进行CW520丙烯酸盐化学灌浆材料配方试验研究,确定了其配方。对这种浆液和凝胶体的性能测试表明:CW520丙烯酸盐化学灌浆材料具有粘度低、流动性好、可灌入细微裂缝、凝胶时间可控、渗透系数低、固砂体抗压强度较高等特点,具有很好的推广利用价值。

Abstract: The method of synthesizing a non-toxic and water-soluble cross-linker is introduced. This novel cross-linker could replace the ordinary cross-linking agent N’-Methylenebisacrylamide, a material neither easily dissolved nor environmental-friendly, which is commonly used in acrylate grouting. The ingredients of CW520 acrylate chemical grouting material synthesized by this new cross-linker have been determined. Tests on the mechanical properties of slurries and gels indicate that CW520 acrylate grouting material is featured by low viscosity, good fluidity, low osmotic coefficient, and can be injected into tiny cracks with controllable gelling time and high compressive strength of consolidated sand. It’s of great practical value and could be utilized widely.

Key words: acrylate, cross-linking agent, synthesis, chemical grouting, properties of slurry
