Alkali-free fluorine-free liquid accelerator as well as preparation and application thereof
The invention belongs to the technical field of building materials, and particularly relates to a preparation method and an application method of an alkali-free fluorine-free liquid accelerator. The alkali-free fluorine-free liquid accelerator is prepared from a coagulation accelerating component, organic alcohol, alcohol amine, a suspension stabilizer, a nano material, a pH regulator and water. The alkali-free fluorine-free liquid accelerator has the beneficial effects that the alkali-free fluorine-free liquid accelerator can effectively improve the early strength of sprayed concrete, shorten the setting time of the sprayed concrete and reduce the rebound rate of the sprayed concrete, and is environment-friendly and free of corrosion and pollution. The alkali-free fluorine-free liquid accelerator is suitable for surface layer supporting and leaking stoppage or first-aid repair projects of projects such as tunnels, culverts, side slopes and foundation pits.
本发明属于建筑材料技术领域，具体涉及一种无碱无氟液体速凝剂的制备和使用方法。无碱无氟液体速凝剂由促凝组分、有机醇、醇胺、悬浮稳定剂、纳米材料、pH调节剂和水组成。本发明的有益效果是，本发明的无碱无氟液体速凝剂能有效提高喷射混凝土早期强度，缩短喷射混凝土凝结时间，减少喷射混凝土的回弹率，对环境友好，无腐蚀和污染。本发明适用于隧道、涵洞、边坡、基坑等工程的面层支护以及堵漏或抢修工程。
