The invention relates to the technical field of polymer chemistry and building materials, in particular to a novel viscosity-reducing slump-retaining functional monomer and a preparation method thereof. The novel viscosity-reducing slump-retaining functional monomer comprises the following raw materials: 60 to 65 parts of unsaturated acid, 20 to 30 parts of polyol, 5 to 10 parts of hydroxyl alcohol, 2 to 8 parts of polymeric alcohol, 0.5 to 1 part of an esterification catalyst, 5-10 parts of an initiator, and 2.5 * 10 <-6> to 5 * 10 <-6> parts of a transition metal catalyst. The invention aims to provide the novel viscosity-reducing slump-retaining functional monomer which has good compatibility with HPEG and TPEG. After the monomer is added in the synthesis process of the mother liquor of the polycarboxylic acid water reducer, the viscosity reduction function of the mother liquor can be improved, and the plasticity retaining property of the mother liquor is improved.
本发明涉及高分子化学及建筑材料技术领域，具体涉及一种新型降粘保坍功能单体及制备方法，其原料包括不饱和酸60～65份；多元醇20～30份；羟基醇5～10份；聚合醇：2～8份；酯化催化剂0.5～1份，引发剂5～10份；过渡金属催化剂：2.5×10‑6～5×10‑6份。本发明的目的是提供一种新型降粘保坍功能单体，它与HPEG及TPEG具有良好的相容配伍性。在聚羧酸减水剂母液的合成过程中加入该单体后能够提升母液的降粘功能、增加母液的保塑性。
