Thixotropic agent for ultra-high-performance sprayed concrete and preparation method and device of thixotropic agent
The invention discloses a thixotropic agent for ultra-high-performance sprayed concrete and a preparation method and device of the thixotropic agent, and belongs to the technical field of ultra-high-performance concrete for spraying building materials, and the thixotropic agent is prepared from the following components in parts by weight: 250-500 parts of aluminum sulfate; 5 to 15 parts of aluminum hydroxide gel; 10-40 parts of a crystal nucleus early strength agent; 10 to 35 parts of triethanolamine; 30 to 90 parts of silicon phosphate; 0.5 to 4 parts of trimellitic anhydride; 1 to 10 parts of disodium ethylene diamine tetraacetate; 5 to 20 parts of sodium polyphosphate; 0.5 to 4 parts of cellulose ether; and 250 to 520 parts of deionized water. The preparation method comprises the following steps: weighing; deionized water is added; adding the mixture into a preparation device; triethanolamine and a crystal nucleus early strength agent are added; the device comprises a reaction kettle, a jacket, a driving mechanism, a stirring mechanism, a feeding column and an outer pipe. The thixotropic agent is good in stability, appropriate in price, good in thixotropic performance, high in early strength and good in effect.
本发明公开了一种超高性能喷射混凝土用触变剂及其制备方法、装置，属于建筑材料喷射用超高性能混凝土技术领域，该触变剂由以下重量份数的组分组成：硫酸铝250～500份；氢氧化铝凝胶5～15份；晶核早强剂10～40份；三乙醇胺10～35份；磷酸硅30～90份；偏苯三酸酐0.5～4份；乙二胺四乙酸二钠1～10份；多聚磷酸钠5～20份；纤维素醚0.5～4份；去离子水250～520份。其制备方法包括称取；加去离子水；将混合物加入到制备装置中；加入三乙醇胺、晶核早强剂。其装置包括反应釜、夹套、驱动机构、搅拌机构、进料柱和外管。本触变剂稳定性好、价格适宜、触变性能佳，且早期强度高，效果好。
