Waterproof plugging type material for pipeline joint and preparation method of waterproof plugging type material
The invention relates to a waterproof plugging type material for a pipeline interface and a preparation method thereof, and belongs to the technical field of constructional engineering. The prepared waterproof plugging type material is mainly composed of water, cement, sand, silica fume, organic modified bentonite, a water reducing agent and a waterproof agent, the water-binder ratio of mortar is optimized, the organic modified bentonite is added as a functional filler, the organic modifier and cations in the bentonite are subjected to an ion exchange effect, the characteristics of a high-molecular polymer are combined, and the waterproof plugging type material is prepared. The modified bentonite has a relatively good surface structure and a good bonding effect with concrete; the coconut oil with a good gelling effect is used as a waterproof agent, is environment-friendly, easy to obtain and good in cohesiveness, so that the filling of a mortar system is more compact, and the porosity is relatively low; the additive silica fume is adopted, the naphthalene water reducer is supplemented, SiO2 particles in the silica fume are uniformly distributed in a mortar system, the particle combination in the structure is optimized, pores in the mortar are reduced, the plugging effect is good, and the good waterproof plugging effect is achieved.
本发明涉及一种用于管道接口的防水封堵型材料及其制备方法，属于建筑工程技术领域。本发明制备的防水封堵型材料主要由水、水泥、砂、硅灰、有机改性膨润土、减水剂和防水剂组成，通过优化砂浆水胶比，有机改性膨润土作为功能填料加入，有机改性剂与膨润土中的阳离子发生离子交换作用，结合了高分子聚合物的特性，改性后的膨润土具有较好的表面结构，与混凝土的粘结效果好；具有良好胶凝效果椰子油作为防水剂，环保易得且粘结性好，使砂浆体系的填充更为密实，孔隙率相对较低；采用外加剂硅灰，辅以萘系减水剂，硅灰中SiO2颗粒均匀的分布在砂浆体系中，优化结构内部颗粒集配，减少了砂浆内部的孔隙，封堵效果好，达到了良好的防水封堵的效果。
