High-toughness wear-resistant epoxy resin polymer mortar and application method thereof
The invention discloses high-toughness wear-resistant epoxy resin polymer mortar. The epoxy resin polymer mortar is mainly applied to surface repair, reinforcement and protection of an overflowing part of a hydraulic structure, and is prepared by mixing and stirring the following components in parts by weight: 15-20 parts of epoxy resin slurry, 2-4 parts of an active diluent, 6-8 parts of a curingmixture, 70-80 parts of a filler mixture and a toughening modification material. The filler mixture is prepared by mixing the following raw materials in percentage by weight: 90% of graded SiC, 3%-5%of cast stone powder, 4%-6% of fine graphite powder, 0.5% of fumed silica and 0.5% of rutile titanium dioxide. The toughening modification material is prepared by mixing the following raw materials:SE1430 type graphene accounting for 0.02-0.04% of the total mass of the epoxy resin polymer mortar, 5-mm chopped carbon fiber yarns accounting for 0.15-0.2% of the total mass of the epoxy resin polymer mortar, a dispersing agent accounting for 0.05% of the total mass of the epoxy resin polymer mortar, and water accounting for 0.05% of the total mass of the epoxy resin polymer mortar. The epoxy resin polymer mortar has good toughness and abrasion resistance on the basis of guaranteeing good compressive strength and bonding strength.
本发明公开了一种高韧性耐磨环氧树脂聚合物砂浆，主要应用于水工建筑物过流部位的表面修补加固和防护，按重量份数由15‑20份的环氧树脂浆料、2‑4份活性稀释剂、6‑8份固化混合物、70‑80份填料混合物以及增韧改性材料混合拌制而成；填料混合物有以下重量百分比的原料混合而成：90%的级配SiC、3%‑5%的铸石粉、4%‑6%的石墨精粉、0.5%的气相白炭黑、0.5%的金红石钛白粉；增韧改性材料由以下原料混合而成：占环氧树脂聚合物砂浆总体质量的0.2‰‑0.4‰的SE1430型石墨烯、占环氧树脂聚合物砂浆总体质量的1.5‰‑2‰的5mm短切碳纤维丝、占环氧树脂聚合物砂浆总体质量的0.5‰的分散剂和5‰水；该环氧树脂聚合物砂浆在保证良好的抗压强度和粘接强度的基础上具有良好的韧性和抗冲磨性能。
