| 摘 要： | 通过对羧酸系减水剂与粘土作用机理的分析,按照DLVO双电层理论和空间位阻理论进行聚羧酸系陶瓷减水剂的分子设计,选用丙烯酸、甲基丙烯磺酸钠为原料,通过水溶液调节共聚合的方法合成了一种线型聚羧酸系高效陶瓷减水剂。研究了单体配比、引发剂种类及用量、反应时间及反应温度等因素对减水剂结构和性能的影响。结果表明,在温度为80℃条件下以过氧化物为引发剂,AA∶MAS摩尔配比为3∶1,反应5小时,减水剂的性能最佳,在添加量为0.4%～0.6%范围内,其减水率可达32%。

| Abstract: | In this paper,the mechanism of reaction between polycarboxylate superpla-sticizer and clay was analyzed. The molecular of a linear carboxylate plasticizer is designed according to the electric double layer negative electricity repulsion effect of DLVO theory. A kind of linear carboxylate superplasticizer was synthesized with crylic acid(AA) and Sodium Methylallyl Sulfonate (MAS) through the aqueous copolymerization. The factors influencing on performance of copolymer such as the kind and dosage of initiator... |
