Foam-stabilizing thickening agent, preparation method thereof and concrete
The invention discloses a foam-stabilizing thickening agent, a preparation method thereof and concrete. The invention discloses a foam-stabilizing thickening agent for promoting dissolution of minerals and a preparation method of the foam-stabilizing thickening agent. The foam-stabilizing thickening agent is prepared from the following components: acrylic acid, hydroxyethyl acrylate, a dissolution promoter, an initiator and a chain transfer agent. Wherein the molar ratio of the acrylic acid to the hydroxyethyl acrylate is (3-5): 1; the average molecular weight of the foam stabilizing and thickening agent is 20000 to 50000. The foam-stabilizing thickening agent provided by the invention can be widely applied to concrete, has an obvious dissolution promoting effect and an excellent thickening effect, is free of segregation and bleeding, and has a strength growth rate greater than 5% after curing for 28 days; the preparation method provided by the invention is simple and rapid.
一种稳泡增稠剂及其制备方法、混凝土。本发明公开了一种下式所示的促进矿物溶解的稳泡增稠剂及其制备方法，该稳泡增稠剂由下述组分制得：丙烯酸及丙烯酸羟基乙酯、促溶剂、引发剂和链转移剂。其中，丙烯酸与丙烯酸羟基乙酯的摩尔比为(3‑5):1；稳泡增稠剂的平均分子量为20000‑50000。本发明提供的稳泡增稠剂可广泛应用于混凝土，促溶效果明显，增稠效果优异，不离析、不泌水，养护28d强度增长率大于5％；本发明提供的制备方法简单快捷。
