Polycarboxylate superplasticizer with high adsorption and mud blocking functions and preparation method of polycarboxylate superplasticizer
The invention relates to the technical field of concrete admixtures, in particular to a polycarboxylate superplasticizer with high adsorption and mud blocking functions and a preparation method of the polycarboxylate superplasticizer. The polycarboxylate superplasticizer with the high-adsorption mud-blocking function is prepared from the following preparation raw materials: a modified polyether macromonomer, unsaturated acid, a quaternary ammonium salt cationic monomer, a phosphonate-based monomer, an unsaturated sulfonic acid group, an initiator, a chain transfer agent and a neutralizer. The polycarboxylate superplasticizer with the high-adsorption mud-blocking function has good adsorption dispersion performance and mud-blocking performance, the adsorption capacity to cement particles can be effectively enhanced, the influence of the mud content in gravel on adsorption dispersion is inhibited, the mud-blocking capacity of the polycarboxylate superplasticizer is obviously improved, and the concrete performance of the polycarboxylate superplasticizer is improved.
本发明涉及混凝土外加剂技术领域，特别涉及一种具有高吸附阻泥功能的聚羧酸减水剂及其制备方法，其中，所述具有高吸附阻泥功能的聚羧酸减水剂包括以下制备原料：改性聚醚大单体、不饱和酸、季铵盐阳离子单体、膦酸酯基单体、不饱和磺酸基团、引发剂、链转移剂和中和剂。本发明提供的具有高吸附阻泥功能的聚羧酸减水剂具有良好的吸附分散性能以及阻泥性能，能够有效增强对水泥颗粒的吸附能力，抑制砂石中含泥量对吸附分散的影响，明显提高聚羧酸减水剂的阻泥能力，有助于改善其混凝土性能。
