Preparation method of high slump loss resistance type polycarboxylate superplasticizer
The invention discloses a high slump loss resistance type water reducing agent and a preparation method thereof. The high slump loss resistance type water reducing agent is prepared from unsaturated isopentenyl polyoxyethylene ether macromonomers, unsaturated carboxylic acid, polysaccharides and alkyl alcohols through free radical solution copolymerization under a normal pressure condition, can becontinuously released in concrete, provides excellent slump loss resistance, and has relatively excellent slump loss resistance for commercially available inferior sand and gravel materials.
本发明公开了一种高保坍型减水剂及其制备方法，由不饱和异戊烯基聚氧乙烯醚类大单体、不饱和羧酸、多元糖、烷基醇类在常压条件下采用自由基溶液共聚而成，其能在混凝土中持续释放，提供了卓越的保坍性能，针对目前市场劣质砂石料也依旧能保证比较优异的保坍性。
