Water reducing and slump retaining type water reducing agent and preparation method thereof
The invention discloses a water-reducing and slump-retaining type water reducing agent and a preparation method thereof. The water-reducing and slump-retaining type water reducing agent has a structure as shown in a structural formula (1). Compared with a traditional polycarboxylic acid water reducing agent, the water-reducing slump-retaining type water reducing agent has better slump-retaining capacity, water reducing performance and slump-retaining performance can be considered at the same time, the water reducing rate can reach 30%, concrete slump is basically not lost within 3 h, and the sensitivity and cement adaptability of the polycarboxylic acid water reducing agent are effectively improved.
本发明公开一种减水保坍型减水剂及其制备方法，所述减水保坍型减水剂具有结构式(1)所示的结构。本发明提供的减水保坍型减水剂相较于传统聚羧酸减水剂具有更好的保坍能力，能够同时兼顾减水性能和保坍性能，其中减水率可达30％，且3h混凝土坍落度基本无损失，有效改善了聚羧酸减水剂的敏感性和水泥适应能力。
