Polycarboxylate superplasticizer miscible with defoaming agent and preparation method thereof
The invention relates to the technical field of superplasticizers, provides a polycarboxylate superplasticizer miscible with a defoaming agent and a preparation method thereof, and is characterized in that the polycarboxylate superplasticizer miscible with the defoaming agent adjusts a hydrophilic-oleophylic equilibrium value of water reducing agent molecules by introducing short-chain unsaturated oleophylic small monomers to achieve purpose of being compatible with defoaming agent. According to the technical scheme, the problem that in the prior art, a polycarboxylate high-performance superplasticizer and a compound defoaming agent are difficult to be compatible is solved.
本发明涉及减水剂技术领域，提出了一种可与消泡剂混溶型聚羧酸减水剂及其制备方法，其特征在于，所述可与消泡剂混溶型聚羧酸减水剂通过引入短链不饱和亲油小单体，调整减水剂分子亲水亲油平衡值达到与消泡剂相容的目的。通过上述技术方案，解决了现有技术中的聚羧酸系高性能减水剂复配消泡剂难相容的问题。
