High-water-reduction type EPEG polycarboxylic acid water reducer and preparation method thereof
The invention relates to the field of concrete admixtures, in particular to a high-water-reduction type EPEG polycarboxylic acid water reducer and a preparation method thereof. The high-water-reduction type EPEG polycarboxylic acid water reducer comprises ethylene glycol monovinyl polyethylene glycol ether (EPEG), an unsaturated acid monomer, an amide polymer, unsaturated carboxylic acid/anhydride, unsaturated sulfonate and a function regulator, wherein the function regulator is a polymer of an unsaturated alcohol amine compound, an unsaturated ester monomer and an unsaturated phosphoric acid monomer. The high-water-reduction type EPEG polycarboxylic acid water reducer provided by the invention has the advantages of low temperature requirement, wide adaptability, fast preparation and high efficiency, has high water reducing property and good dispersibility compared with similar products, and can solve the problems of poor neutrality and too fast loss of concrete raw materials.
本发明涉及混凝土外加剂领域，特别涉及一种高减水型EPEG类聚羧酸减水剂及其制备方法。其中，一种高减水型EPEG类聚羧酸减水剂，包括乙二醇单乙烯基聚乙二醇醚(EPEG)、不饱和酸类单体、酰胺类聚合物、不饱和羧酸/酸酐、不饱和磺酸盐及功能调节剂；其中，所述功能调节剂为不饱和醇胺类化合物、不饱和酯类单体及不饱和磷酸单体的聚合物。本发明提供的高减水型EPEG类聚羧酸减水剂对温度要求低，适合性广，制备快且效率高，与同类产品对比，减水性高，分散性好，能够解决混凝土原材料中和易性差和损失过快的问题。
