【摘要】：以二甲基二烯丙基氯化銨與甲基烯丙基聚氧乙烯醚、丙烯酸等單體共聚制備了一種新型聚羧酸系高性能減水劑母液,通過實(shí)驗(yàn)得到最佳合成工藝為:n(丙烯酸)∶n(TPEG2000)=4.0∶1.0,DADMAC用量為單體總物質(zhì)的量的20%,反應(yīng)溫度70℃,反應(yīng)時間3.0~3.5 h。該減水劑可有效解決砂含泥量過高造成混凝土工作性下降的問題,對混凝土砂石料的適應(yīng)性強(qiáng),并具有良好的增強(qiáng)和保坍性。
[Abstract]:A new type of polycarboxylic acid superplasticizer mother liquor was prepared by copolymerization of dimethyl diallyl ammonium chloride with methyl allyl polyoxyethylene ether and acrylic acid. Through experiments, the optimum synthesis process was obtained as follows: 1: n (TPEG2000): 4.0: 1.0% DADMAC was 20% of the total monomer, the reaction temperature was 70 鈩，
