Problems solved by technology

[0003] With the development of epoxy resin grouting material technology, higher requirements are put forward for the strength, fluidity and environmental performance of the material. Due to the high viscosity of epoxy resin, even some epoxy resin exists in a solid state. Therefore, a large amount of diluent is usually added to reduce the viscosity of the material during use, but the existing diluent is extremely volatile and highly toxic during use, which brings many hidden dangers to the production and use process. In addition, due to aldol condensation The dilution system is very volatile, and the epoxy system itself has the characteristics of curing and shrinkage, resulting in a large shrinkage rate after curing, which seriously affects the bonding performance and filling and reinforcing effect of the grouting material. Therefore, a low-toxicity and filling effect is required. Well, especially epoxy grouting materials that will not shrink after grouting is cured to meet the current production needs for epoxy grouting materials. For this reason, we propose a low-toxic epoxy resin grouting material for construction and its preparation method to solve the above problems
