Epoxy resin concrete for catch basin and preparation process of epoxy resin concrete
The invention relates to the technical field of concrete, in particular to epoxy resin concrete for a catch basin and a preparation process thereof. The cement, the silica fume, the fine aggregate, the coarse aggregate, the water reducing agent, the fly ash, the modified epoxy resin, the curing agent, the diluent and the water are mixed to obtain epoxy concrete slurry, and the epoxy concrete with good mechanical property and ageing resistance for the catch basin is obtained through curing. A preparation process of the modified epoxy resin comprises the following steps: (1) preparing eugenol glycidyl ether by taking eugenol and epoxy chloropropane as raw materials; (2) enabling eugenol glycidyl ether to react with 1, 1, 3, 3-tetramethyldisiloxane, and then grafting 4-isopropylamino diphenylamine, so as to obtain silicon-containing dihydric alcohol; (3) mixing silicon-containing dihydric alcohol and polyethylene glycol, and reacting with isophorone diisocyanate to obtain a silicon-containing polyurethane prepolymer; and (4) mixing the silicon-containing polyurethane prepolymer with epoxy resin to obtain the modified epoxy resin.
本发明涉及混凝土技术领域，具体为一种雨水井用环氧树脂混凝土及其制备工艺。本发明将水泥、硅灰、细骨料、粗骨料、减水剂、粉煤灰、改性环氧树脂、固化剂、稀释剂、水混合得到环氧混凝土浆料，养护得到具有良好力学性能和抗老化性能的雨水井用环氧树脂混凝土；其中，改性环氧树脂的制备工艺：（1）以丁香酚、环氧氯丙烷为原料制备丁香酚缩水甘油醚；（2）将丁香酚缩水甘油醚与1,1,3,3‑四甲基二硅氧烷反应，再接枝4‑异丙氨基二苯胺，得到含硅二元醇；（3）将含硅二元醇、聚乙二醇混合后与异佛尔酮二异氰酸酯反应，得到含硅聚氨酯预聚体；（4）将含硅聚氨酯预聚体与环氧树脂混合，得到改性环氧树脂。
