Urban street sewer well surface damage repairing material and preparation method thereof
The invention discloses an urban street sewer well surface damage repair material and a preparation method thereof, and relates to the technical field of urban infrastructure maintenance, the urban street sewer well surface damage repair material comprises fast hardening sulphoaluminate, ordinary Portland cement, natural washed sand, green gravel, black pigment, an additive and anti-crack glass fiber, the carbon nanotube modified bentonite composite repairing material has the advantages that the carbon nanotube modified bentonite composite repairing material is added into the surface damage repairing material, so that the material can be immersed into an interlayer structure of bentonite, the interlayer spacing of the bentonite is enlarged, harmful substances in the damage repairing material can be effectively adsorbed and fixed, the harmful substances are prevented from polluting the environment, and the service life of the surface damage repairing material is prolonged. The mechanical property and the anti-aging property of the repairing material can be enhanced through high strength and high conductivity of the carbon nano tubes, the repairing material is prevented from being cracked and damaged, and different materials can be tightly connected through chemical bonds in the silane coupling agent by adding the silane coupling agent into the surface damage repairing material.
本发明公开了一种城市街道下水井表面破损修复材料及其制备方法，本发明涉及城市基础设施维护技术领域，包括快硬硫铝酸盐、普通硅酸盐水泥、天然水洗砂、青碎石、黑色颜料、添加剂以及抗裂玻璃纤维，本发明的优点在于：通过在表面破损修复材料中加入碳纳米管改性膨润土复合修复材料，能够使该材料浸入膨润土的层间结构中，扩大膨润土的层间距，在破损修复材料中，能够有效地吸附和固定材料中的有害物质，防止其对环境造成污染，且碳纳米管的高强度和高导电性可以增强修复材料的力学性能和抗老化性能，防止修复材料的开裂和破坏，通过在表面破损修复材料中加入硅烷偶联剂，能够通过其中的化学键将不同材料紧密连接。
