Steel fiber or oriented steel fiber reinforced epoxy resin adhesive and preparation and application methods thereof
The invention relates to a steel fiber or oriented steel fiber reinforced epoxy resin adhesive and a preparation and application method thereof, and relates to the field of civil engineering. The steel fiber or oriented steel fiber reinforced epoxy resin adhesive comprises epoxy resin adhesive and high-strength steel fiber, mixing the high-strength steel fiber into the epoxy resin glue and stirring; stirring to obtain steel fiber reinforced epoxy resin glue; and the high-strength steel fibers are magnetized and oriented through magnetic orientation equipment to form the oriented steel fiber reinforced epoxy resin adhesive. According to the steel fiber or oriented steel fiber reinforced epoxy resin adhesive provided by the invention, the high-strength steel fiber can bear a bridging effect in the reinforced epoxy resin adhesive, and after the reinforced epoxy resin adhesive cracks, the high-strength steel fiber can bridge a substrate at a fracture position and continuously bear a load effect, so that the ductility of a structure is improved, and sudden brittle failure is avoided.
本发明涉及钢纤维或定向钢纤维增强环氧树脂胶及制备、应用方法，涉及土木工程领域。钢纤维或定向钢纤维增强环氧树脂胶，包括环氧树脂胶，高强钢纤维；将高强钢纤维掺入环氧树脂胶中搅拌；搅拌后得到钢纤维增强环氧树脂胶；通过磁性定向设备对高强钢纤维磁化定向形成定向钢纤维增强环氧树脂胶。本发明提供的钢纤维或定向钢纤维增强环氧树脂胶，高强钢纤维在增强环氧树脂胶中可承担“桥接作用”，在增强环氧树脂胶开裂后，能桥接断裂处的基体并继续承受荷载作用，进而提高结构的延性，避免突然发生的脆性破坏。
