Double-expansion inorganic-organic composite crack repairing material and preparation method thereof
The invention belongs to the technical field of building materials and underground engineering and relates to a cement-based repairing material, in particular, a double-expansion inorganic-organic composite crack repairing material suitable for an underground humid environment and a preparation method. The material comprises the following components in parts by weight: cement, sand, a calcium-magnesium expanding agent, silica fume, modified water-based epoxy resin, a curing agent, a defoaming agent, a polycarboxylate superplasticizer, a vulcanizing agent and water; the water-based epoxy resinis water-soluble liquid and is prepared by chemically modifying bisphenol A epoxy resin and a compound containing a hydrophilic group; the weight of the water-based epoxy resin can be indicated by theweight of liquid; the expanding agent is formed by calcining magnesite and dolomite. The double-expansion composite crack repairing material provided by the invention has the characteristics of shortsetting time, good fluidity, high compression strength and breaking strength, vibration resistance, double expansion, no shrinkage, durability, suitability for repairing cracks in an underground humid environment, simplicity in production, convenience in construction and the like.
本发明属于建筑材料和地下工程技术领域，涉及一种水泥基修补材料，特别涉及一种适用地下潮湿环境中双膨胀无机有机复合裂缝修补材料及制备方法，按重量份数计算，包括如下组分：水泥，砂，钙镁质膨胀剂，硅灰，改性水性环氧树脂，固化剂，消泡剂，聚羧酸减水剂，硫化剂，水，其中，水性环氧树脂重量为液体重量，是一种水溶性液体，由双酚A环氧树脂与含有亲水基团化合物经化学改性制得；膨胀剂是由菱镁石和白云石煅烧而成。本发明所提供双膨胀复合式裂缝修补材料具有凝结时间短、流动性好、抗压与抗折强度高、抗震动、双膨胀无收缩、耐久和适合地下潮湿环境裂缝修补、且生产简单及施工方便等特点。
