Super-slow-release polycarboxylic acid slump retaining agent and preparation method thereof
The invention discloses a super-slow-release polycarboxylic acid slump retaining agent and a preparation method thereof. The super-slow-release polycarboxylic acid slump retaining agent is prepared from the following raw materials: a polyether macromonomer, a first slow-release small monomer, a second slow-release small monomer, a third slow-release small monomer, a small monomer, an initiator, achain transfer agent, a reducing agent and a catalyst. The slump retaining agent is simple in process, environmentally friendly, free of pollution and excellent in product slump retaining performance,and the super-long slump retaining effect is achieved by controlling the dual effects of adsorption and ester group hydrolysis.
本发明公开了一种本发明的超徐放型聚羧酸保坍剂及其制备方法,由如下原料组成:聚醚大单体、第一缓释小单体、第二缓释小单体、第三缓释小单体、小单体、引发剂、链转移剂、还原剂以及催化剂组成。本发明的保坍剂工艺简单,环保无污染,且产品保坍性能优异,通过控制吸附和水解酯基双重效应来达到超长保坍功效。
