Phenyl modified polycarboxylic acid slump retaining agent and preparation method thereof
The invention relates to a phenyl modified polycarboxylic acid slump retaining agent and a preparation method thereof. The slump retaining agent is mainly prepared from 352-364 parts of a polyether macromonomer, 5-8 parts of a benzene ring monomer, 8-12 parts of acrylic acid, 18-28 parts of alkyl acrylate, 0.68-1.12 parts of an initiator a, 1.48-1.82 parts of an initiator b, 1.32-1.63 parts of a chain transfer agent, and the balance of water, the number of total parts by mass of the slump retaining agent is 1000, and the solid content is 40%. The polycarboxylic acid slump retaining agent prepared through the method is good in adsorption and dispersion capacity and good in fluidity retentivity.
本发明涉及一种苯基改性聚羧酸保坍剂及其制备方法，主要由以下组分制备而成：聚醚大单体：352‑364份，苯环类单体：5‑8份，丙烯酸：8‑12份，丙烯酸烷基酯：18‑28份，引发剂a：0.68‑1.12份，引发剂b：1.48‑1.82份，链转移剂：1.32‑1.63份，其余为水，总质量为1000份，固含量为40％。通过此法制备的聚羧酸保坍剂吸附分散能力更佳，流动度保持性更好。
