一种结构加固用水性环氧树脂改性水泥砂浆及其制备方法
摘要：
本发明提供了一种结构加固用水性环氧树脂改性水泥砂浆及其制备方法。该水泥砂浆由质量比为1︰1.0～2.5︰10～45︰1.0～7.0的A、B、C三组分和外加的水组成；其中所述A组分由环氧树脂100份、环氧活性稀释剂0～25份、环氧增韧剂8～20份、消泡剂0.1～0.5份组成，所述B组分由固化剂100份、固化促进剂3～10份、偶联剂0.8～2.5份组成，所述C组分由硅酸盐水泥100份、集料100～300份、硅灰5～30份、减水剂0.1～0.5份组成。本发明还提供一种乳化型水性环氧树脂固化剂ZB‑804。本发明制备的水性环氧树脂改性水泥砂浆用于混凝土建筑物和构筑物的修补加固，提高水泥混凝土的耐久性，延长结构使用寿命，保证建筑物安全使用。
摘要（英）：

The invention provides water-borne epoxy resin-modified cement mortar used for structure reinforcement and a production method thereof. The cement mortar is composed of A, B and C components and additional water with a mass ratio of 1 to (1.0 to 2.5) to (10 to 45) to (1.0 to 7.0), wherein the A component is composed of 100 parts of epoxy resin, 0-25 parts of epoxy reactive diluent, 8-20 parts of epoxy flexibilizer and 0.1-0.5 part of defoaming agent, the B component is composed of 100 parts of curing agent, 3-10 parts of curing accelerator and 0.8-2.5 parts of coupling agent, and the C component is composed of 100 parts of silicate cement, 100-300 parts of aggregate, 5-30 parts of silica fume and 0.1-0.5 part of water reducer. The invention further provides an emulsion-type water-borne epoxy resin curing agent ZB-804. The produced water-borne epoxy resin-modified cement mortar is used for repair and reinforcement of concrete buildings and structures, the durability of cement concrete is improved, the service lives of the structures are prolonged, and safe use of the buildings is guaranteed.
