Title
(EN) Long-acting slow-release polycarboxylic acid slump retaining agent and preparation method thereof
(ZH) 一种长效缓释型聚羧酸保坍剂及其制备方法
Abstract
(EN)
The invention discloses a long-acting slow-release polycarboxylic acid slump retaining agent and a preparation method thereof. The preparation method comprises the following steps: firstly, esterifying: reacting methacrylic acid, saturated acid and 3-bis(2-ethoxy)-amino-2-hydroxypropionic acid under the action of a catalyst to obtain an unsaturated esterified small monomer; putting cumenyl polyoxyethylene, unsaturated monocarboxylic acid, 3-butylenyl phosphonate and the like into a backing material, and respectively dropwise adding a photoinitiator (a first solution) dissolved into the deionized water, a chain transfer agent, the unsaturated monocarboxylic acid, the unsaturated esterified small monomer and unsaturated carboxylic acid ester (a second solution) into the backing material forreaction and polymerization; thirdly, adding pH regulating liquid for neutralizing after thermal insulation is finished, thus obtaining a finished product. The slump retaining agent prepared with thepreparation method disclosed by the invention has good slump retention ability in a long time.
