Alcohol amine modified hydrated calcium silicate nanocrystal nucleus early strength agent and preparation method thereof
The invention discloses an alcohol amine modified hydrated calcium silicate nanocrystal nucleus early strength agent which is prepared from a reaction stock solution, a reaction base solution and a dispersion stabilizing solution, and the reaction stock solution comprises the following components: soluble calcium salt and soluble silicon salt; the reaction base solution comprises the following components: a polycarboxylate high-efficiency water reducing agent; the dispersion stabilizing solution comprises the following components: a soluble alcohol amine organic matter and a soluble aluminum salt. The alcohol amine modified hydrated calcium silicate nanocrystal nucleus early strength agent solves the problem of long-term dispersion stability of a hydrated calcium silicate crystal nucleus suspension liquid, and is small in initial particle size, long in dispersion stabilization time, resistant to storage, simple in preparation process and use method, remarkable in early and later strength improvement effect on cement-based materials and excellent in performance. The invention also discloses a preparation method of the alcohol amine modified hydrated calcium silicate nanocrystal nucleus early strength agent.
本发明公开了一种醇胺改性水化硅酸钙纳米晶核早强剂，其由反应原液、反应底液和分散稳定液制得，所述反应原液包括如下组分：可溶性钙盐和可溶性硅盐；所述反应底液包括如下组分：聚羧酸高效减水剂；所述分散稳定液包括如下组分：可溶性醇胺有机物和可溶性铝盐。该醇胺改性水化硅酸钙纳米晶核早强剂解决了水化硅酸钙晶核悬浮液的长期分散稳定性的问题，且其初始粒径细小，分散稳定时间长、耐储存，制备工艺及使用方法简单，对水泥基材料早期、后期强度提升效果显著，表现优异。本发明还公开了一种该醇胺改性水化硅酸钙纳米晶核早强剂的制备方法。
