Anti-static self-leveling waterborne epoxy cement mortar and preparation method thereof
The invention belongs to the technical field of cement mortar, and provides anti-static self-leveling waterborne epoxy cement mortar. The conductive fibers and the single-arm carbon nanotubes are added into the waterborne epoxy emulsion to serve as conductive media, so that the resistance of the mortar is very stable, and the resistance value cannot be infinitely increased along with abrasion of a paint film; a high-performance organic-inorganic composite material with a spatial net-shaped structure is formed through cross-linking solidification of the waterborne epoxy emulsion and hydration of the cement, the composite material can be solidified under a wet interface, the effects of reinforcement and permeation resistance are achieved, the compressive strength of the cement mortar is improved, and meanwhile by adopting a low water-cement ratio, the water-cement mortar can be applied to cement mortar. Part of the composite cement is surplus and can react with water vapor permeating from a wet base plane, osmotic pressure is eliminated, and the effect of a damp-proof layer is achieved. The result of the embodiment shows that the compressive strength of the anti-static self-leveling waterborne epoxy cement mortar provided by the invention is 74 MPa, and the bonding strength is 2.2 MPa.
本发明属于水泥砂浆技术领域，提供了一种防静电自流平水性环氧水泥砂浆。本发明通过在水性环氧乳液中添加导电纤维和单臂碳纳米管作为导电介质，使得砂浆的电阻非常的稳定，不会随着漆膜的磨损电阻值会无限变大；通过水性环氧乳液的交联固化及水泥的水化作用形成具有空间网状结构的高性能的有机‑无机复合材料，可在潮湿界面下固化，起到增强、抗渗透的作用，提高了水泥砂浆的抗压强度，同时通过采用较低的水灰比，复合的水泥有一部分是富余的，可以和潮湿基面渗透进来的水汽反应，消除渗透压，起到防潮层作用。实施例的结果显示，本发明提供的防静电自流平水性环氧水泥砂浆的抗压强度为74MPa，粘接强度为2.2MPa。
