Nano silicon dioxide and hybrid fiber reinforced epoxy resin cement-based repair material and preparation method thereof
The invention belongs to the technical field of repair materials, and discloses a nano silicon dioxide and hybrid fiber reinforced epoxy resin cement-based repair material and a preparation method thereof. The epoxy resin cement-based repair material is prepared from the following raw materials: cement, quartz sand, water, epoxy resin emulsion, an epoxy resin curing agent, nano silicon dioxide, polyvinyl alcohol fibers, steel fibers, a defoaming agent and a water reducing agent. In the prepared epoxy resin cement-based repair material, the epoxy resin emulsion is combined with the nano SiO2, the polyvinyl alcohol fiber and the steel fiber, so that the cohesiveness of the repair material can be obviously enhanced, the bonding effect is enhanced, and the fluidity is reduced; the epoxy resin cement-based repair material prepared by the invention has excellent breaking strength, splitting tensile strength and interface flexural tensile strength.
本发明属于修复材料技术领域，本发明公开了一种纳米二氧化硅和混杂纤维增强的环氧树脂水泥基修复材料及其制备方法，环氧树脂水泥基修复材料的原料包括水泥、石英砂、水、环氧树脂乳液、环氧树脂固化剂、纳米二氧化硅、聚乙烯醇纤维、钢纤维、消泡剂和减水剂。本发明所制得的环氧树脂水泥基修复材料中，环氧树脂乳液与纳米SiO2、聚乙烯醇纤维和钢纤维相结合，能够明显增强修复材料的粘聚性，从而增强粘结作用降低流动性；本发明所制得的环氧树脂水泥基修复材料具有优异的抗折强度、劈裂抗拉强度、界面弯拉强度。
