Crystal nucleus type early strength agent for wet-mixed mortar and preparation method of crystal nucleus type early strength agent
The invention discloses a crystal nucleus type early strength agent for wet-mixed mortar and a preparation method of the crystal nucleus type early strength agent. The crystal nucleus type early strength agent is prepared from the following components in parts by weight through reaction: 15-25 parts of a dispersing agent, 15-25 parts of soluble aluminum salt, 18-22 parts of soluble calcium salt, 18-35 parts of soluble silicon salt, 4-6 parts of hydrophilic white carbon black and 405-430 parts of deionized water. The dispersing agent containing phosphate and the soluble aluminum salt are used for improving the dispersion effect of a system, then the hydrophilic white carbon black is introduced as a stabilizer, the stability of the system is further improved, the crystal nucleus type early strength agent prepared through the method has the advantages of being high in stability and obvious in early strength improvement, the middle and later strength can be improved to a certain degree, and the early strength agent is suitable for large-scale production. Therefore, the requirements on strength and durability of the wet-mixed mortar are met.
本发明公开了一种用于湿拌砂浆的晶核型早强剂及其制备方法，其由如下重量份的组分反应制备而成：分散剂15‑25重量份、可溶性铝盐15‑25重量份、可溶性钙盐18‑22重量份、可溶性硅盐18‑35重量份、亲水型白炭黑4‑6重量份和去离子水405‑430重量份。本发明利用含磷酸酯的分散剂和可溶性铝盐来提高体系分散作用，再引入亲水型白炭黑作为稳定剂，进一步增加体系稳定性，通过此方法制得的晶核型早强剂具有稳定性高、提升早期强度明显的优点，并且在一定程度上能提升中后期强度，不倒缩，满足湿拌砂浆强度和耐久性要求。
