Aromatic carboxylic ester intermediate, preparation method thereof and application of aromatic carboxylic ester intermediate in ester type polycarboxylate superplasticizer
The invention provides an aromatic carboxylic ester intermediate, a preparation method thereof and application of the aromatic carboxylic ester intermediate in an ester type polycarboxylate superplasticizer. The main chain of the aromatic intermediate is phenyl and -CH2- which are distributed at intervals. The aromatic intermediate has a carboxylic acid ester side chain. The aromatic carboxylic ester intermediate is a polycarboxylate superplasticizer obtained by introducing a hydrophobic group into a subsequently synthesized superplasticizer macromolecule and carrying out ester exchange reaction with a polyether macromonomer. The monomer conversion rate is high, the hydrophobic structure is adjustable, and the aromatic carboxylic ester intermediate has excellent workability improvement and slump retaining performance.
本发明提供一种芳香族羧酸酯中间体及其制备方法和其在酯型聚羧酸减水剂的应用；所述芳香族中间体的主链为间隔分布的苯基和‑CH2‑；其具有羧酸酯侧链；所述芳香族羧酸酯中间体为后续合成的减水剂大分子引入疏水基团，且与聚醚大单体经酯交换反应获得的聚羧酸减水剂，单体转化率高、疏水结构可调、具有优异的和易性改善和保坍性能。
