High-strength epoxy resin repair mortar and preparation method thereof
The invention discloses high-strength epoxy resin repair mortar and a preparation method thereof. The repair mortar comprises a component A and a curing agent, the component A and the curing agent are mixed according to the mass ratio of 3-5:1, and the component A is prepared from, by weight, 50-60 parts of modified epoxy resin, 40-50 parts of quartz sand and 10-15 parts of glass fiber. The modified epoxy resin is prepared from epoxy resin, p-toluene sulfonic acid, an organosilicon copolymer and a solvent, and the organosilicon copolymer is prepared from an organosilicon monomer, tetraethoxysilane, ethanol and sodium carbonate. The reason of using the epoxy resin as the main raw material of the repair mortar is that the epoxy resin has certain chemical resistance, heat resistance and electrical insulation performance, and the mortar prepared by using the epoxy resin as the raw material has a relatively strong adhesive force effect.
本发明公开了一种高强度环氧树脂修补砂浆及其制备方法，所述修补砂浆包括甲组分和固化剂，甲组分与固化剂按照质量比的3‑5:1混合而成，所述甲组分由以下重量份数的原料制成，改性环氧树脂50‑60份、石英砂40‑50份、玻璃纤维10‑15份，所述改性环氧树脂由环氧树脂、对甲基苯磺酸、有机硅共聚物和溶剂制成，所述有机硅共聚物由有机硅单体、正硅酸乙酯、乙醇和碳酸钠制成。本发明使用环氧树脂作为修补砂浆的主要原料原因在于环氧树脂具一定的耐化学、耐热和电绝缘性能，以环氧树脂为原料制备成的砂浆具有较强的附着力的效果。
