High-strength epoxy grouting material for low-temperature environment and preparation method of high-strength epoxy grouting material
The invention relates to a high-strength epoxy grouting material for a low-temperature environment and a preparation method thereof.The high-strength epoxy grouting material comprises a component A and a component B. The component A comprises, by weight, 280-400 parts of epoxy resin, 450-650 parts of aggregate, 90-220 parts of powder, 18-32 parts of a coupling agent and 8-25 parts of a thixotropic agent; the component B comprises the following components in parts by weight: 100-150 parts of a curing agent, 90-150 parts of powder and 2-10 parts of a thixotropic agent; the viscosity of the epoxy resin at the temperature of 25 DEG C is 2000 to 5000 mPa. S. The epoxy grouting material disclosed by the invention is suitable for being used in a low-temperature environment, is high in strength, not only has good flowability, but also has excellent physical and mechanical properties such as compressive strength, breaking strength and bonding strength, and has remarkable advantages for solving the problem of grouting reinforcement of a structural foundation.
本发明涉及一种低温环境用高强度环氧灌浆料及其制备方法，包括A组分和B组分，按重量份计，所述A组分包含环氧树脂280～400份、集料450～650份、粉料90～220份、偶联剂18～32份和触变剂8～25份；按重量份计，所述B组分包含固化剂100～150份、粉料90～150份和触变剂2～10份；所述环氧树脂在25℃下的粘度为2000～5000mPa.s。本发明的环氧灌浆料适用于低温环境使用，且强度高，其不仅具有良好的流动性，还具有优异的抗压强度、抗折强度和粘结强度等物理力学性能，对于解决结构基础灌浆加固有显著优势。
