Low-temperature anti-freezing type early-strength alkali-free accelerator composition, accelerator as well as preparation method and application of low-temperature anti-freezing type early-strength alkali-free accelerator composition
The invention relates to the field of building materials, and discloses a low-temperature anti-freezing early-strength alkali-free accelerator composition, an accelerator as well as a preparation method and application of the accelerator. The low-temperature anti-freezing early-strength alkali-free accelerator composition contains aluminum sulfate, triethanolamine, a composite anti-freezing agent, an alcohol compound, a stabilizer and a pH regulator, the composite anti-freezing agent is a product obtained by a method comprising the following steps: in the presence of water I, calcium nitrate, diethanolisopropanolamine, acrylamide, ethylene glycol and ursolic acid are subjected to a contact reaction. The low-temperature anti-freezing early-strength alkali-free accelerator prepared by the method provided by the invention is high in early strength, good in stability and good in anti-freezing effect on concrete.
本发明涉及建筑材料领域，公开了一种低温防冻型早强无碱速凝剂组合物、速凝剂及其制备方法和应用。该低温防冻型早强无碱速凝剂组合物中含有硫酸铝、三乙醇胺、复合防冻剂、醇化合物、稳定剂、pH调节剂；所述复合防冻剂为采用包括如下步骤的方法获得的产物：在水I存在下，将硝酸钙、二乙醇单异丙醇胺、丙烯酰胺、乙二醇与熊果酸进行接触反应。本发明提供的方法制备的低温防冻型早强无碱速凝剂的早期强度高、稳定性好、且对混凝土的防冻效果好。
