【摘要】 磺酸基是聚羧酸减水剂中的主导官能团,目前对磺酸基团单体的选择较混乱。对乙烯基磺酸钠、丙烯基磺酸钠、甲基丙烯磺酸钠、苯乙烯磺酸钠、2-丙烯酰胺-2-甲基丙磺酸对聚羧酸减水剂性能的影响进行正交实验,采用SPSS软件分析了各因素的影响,并用多元线性回归得出掺减水剂水泥净浆流动度与磺酸基单体用量、丙烯酸用量、引发剂用量、链转移剂用量的方程。更多还原

【Abstract】 Sulfonic group is a leading functional group in polycarboxylic acid superplasticizer.The selection of sulfonic group is in disorder at present.Cross-cut test is made on influence of sodium vinylsulfonate,sodium allylsulfonate,sodium methyl acryl sulfonate,sodium styrene sulfonate and 2-acrylamido-2-methyl-1-propane sulfonic acid upon the performance of polycarboxylic acid superplasticizer,the effect of each factor is analyzed using SPSS software and equation between the fluidity of cement grout and dosages of sulfonic group,acrylic acid,initiator and chain transfer agent is obtained through multiple regression analysis.更多还原
