Alkaline liquid accelerator and preparation method thereof
The invention discloses an alkaline liquid accelerator and a preparation method thereof. The method comprises the steps of preparing an alkaline liquid accelerator mother liquor by adopting a mixed solution of sodium hydroxide and aluminum hydroxide, preparing an alkaline liquid accelerator mother liquor compound stabilizer by adopting a mixed solution of an alcohol amine compound and carboxylic acid, and compounding the alkaline liquid accelerator mother liquor and the alkaline liquid accelerator mother liquor compound stabilizer, and uniformly stirring to obtain the finished alkaline liquidaccelerator. The alkaline liquid accelerator has good adaptability to ordinary Portland cement and ordinary Portland low-alkali cement, is a high-performance, high-strength and low-alkali accelerator,and is suitable for shotcrete construction in the field of underground engineering construction of highways, railways, mines and the like.
本发明公开了一种有碱液体速凝剂及其制备方法，该方法为：采用氢氧化钠和氢氧化铝的混合溶液制备有碱液体速凝剂母液，采用醇胺类化合物与羧酸的混合溶液制备有碱液体速凝剂母液复配稳定剂，将有碱液体速凝剂母液和有碱液体速凝剂母液复配稳定剂进行复配，搅拌均匀后即得成品有碱液体速凝剂。本发明的有碱液体速凝剂对普通硅酸盐水泥、普通硅酸盐低碱水泥都有很好的适应性，是一种高性能、高强度低碱速凝剂，适用于公路、铁路、矿山等地下工程建筑领域中的喷射混凝土施工。
