Low-temperature underwater epoxy repair mortar and preparation method thereof
The invention discloses low-temperature underwater epoxy repair mortar and a preparation method thereof, and relates to the technical field of building materials, the low-temperature underwater epoxy repair mortar comprises the following components: 60-80 parts of low-viscosity epoxy resin, 20-40 parts of multi-epoxy functional group resin, 35-40 parts of a reactive diluent, 57-67 parts of a curing agent and 518.4-572.4 parts of filler, Dinger-Funk is adopted to optimize filler gradation, and the fluidity of the mortar is improved; the viscosity of the resin is greatly reduced and the fluidity of the mortar is improved by adopting a high-dosage reactive diluent; meanwhile, the polyfunctional epoxy resin is compounded and doped, so that the activity of the resin base solution is improved, the problem that the underwater compressive strength and the bonding strength are reduced due to excessive diluent is solved, the underwater repair construction is convenient, the underwater repair quality is improved, and the safe transportation of the hydraulic release structure is ensured.
本发明公开了一种低温水下环氧修补砂浆及其制备方法，涉及建筑材料技术领域，包括以下组分：60‑80份低黏度环氧树脂、20‑40份多环氧官能团树脂、35‑40份活性稀释剂、57‑67份固化剂和518.4‑572.4份填料，采用Dinger‑Funk优化填料级配，提高砂浆流动性；采用高掺量活性稀释剂大幅度降低树脂黏度，提高砂浆流动性；同时复合掺加多官能团环氧树脂，提高树脂基液活性，解决因稀释剂过多导致的水下抗压强度和粘结强度降低的问题，使水下修补施工方便，并提高了水下修补质量，保证水工泄水建筑物安全运。
