Liquid alkali-free accelerator and preparation thereof
The invention relates to a liquid alkali-free accelerator and preparation thereof. The accelerator is prepared from the following components in parts by weight: 100 parts of aluminum sulfate, 1.00 to1.51 parts of triethanolamine, 0.88 to 1.51 parts of ethylene glycol, 1.40 to 1.93 parts of glycollic acid, 0.51 to 0.54 parts of dibutyl phthalate, 5.26 to 7.02 parts of phosphoric acid and 62.96 to66.39 parts of water. Compared with the prior art, the accelerator has the advantages of favorable stability, low tendency to deteriorate and precipitate, higher retention rates of 1d strength and 28dstrength and the like.
本发明涉及一种液体无碱速凝剂及其制备，速凝剂包括以下重量份数的组分：硫酸铝100份，三乙醇胺1.00‑1.51份，乙二醇0.88‑1.51份，乙醇酸：1.40‑1.93份，邻苯二甲酸二丁酯0.51‑0.54份，磷酸5.26‑7.02份，水62.96‑66.39份。与现有技术相比，本发明具有稳定性好、不易变质沉淀、1d强度和28d强度保有率均较高等优点。
