Normal-temperature self-crosslinking type water-borne epoxy resin modified cement-based mortar two-component material
The invention provides a normal-temperature self-crosslinking type water-borne epoxy resin modified cement-based mortar two-component material. The two-component material contains a component A and a component B, wherein the component A contains 12-30 wt% of a normal-temperature self-crosslinking type water-borne epoxy resin, 0.10-1.0 wt% of an optional defoaming agent and the balance of water according to the total weight of the component A, the epoxy equivalent of the normal-temperature self-crosslinking type water-borne epoxy resin is 300-600, the component B contains cement, gravel, an anti-settling agent, a water reducing agent and a defoaming agent, the component A and the component B are independently packaged, and the two-component material does not contain a curing agent. The invention also provides cement mortar. The cement mortar prepared from the two-component material has the characteristics of excellent mechanical strength, good impact toughness and cracking resistance, excellent water resistance and impermeability, good volume stability, high wear resistance and freezing resistance, rapid hardening, A-level fire prevention, environmental safety and the like.
本发明提供常温自交联型水性环氧树脂改性水泥基砂浆双组分材料。该双组分材料含有A组分和B组分，A组分含有以其总重计含量为12‑30wt％的常温自交联型水性环氧树脂、任选的0.10‑1.0wt％的消泡剂和余量的水，该常温自交联型水性环氧树脂的环氧当量为300‑600，B组分含有水泥、砂石、防沉剂、减水剂和消泡剂，A组分和B组分独立包装，且该双组分材料不含有固化剂。本发明还提供一种水泥砂浆。由该双组分材料制备的水泥砂浆具有优异的力学强度、良好的抗冲击韧性和抗开裂性能、优良的耐水性能和抗渗性、体积稳定性好、高耐磨性和抗冻性、快硬、A级防火、环境安全等特点。
