摘　　要：针对纺织厂空调循环水水质易引起设备管道结垢的问题,以衣康酸(IA)、烯丙基磺酸钠(SAS)、甲基丙烯酸羟乙酯(HEMA)为单体,过硫酸铵为引发剂,叔丁醇为分子量调节剂,采用水溶液自由基共聚合法,合成一种具有多官能团的三元共聚物阻垢剂。研究了共聚物在不同水浴温度条件下对碳酸钙和硫酸钙的阻垢性能,对碳酸钙的阻垢率可达98.25%,对硫酸钙的阻垢率为80.05%。与聚天冬氨酸进行对比,该共聚物对钙盐具有良好的阻垢性能,且高硬水条件下,效果明显优于聚天冬氨酸。通过红外光谱对共聚物进行结构表征,结果表明该共聚物含有多种官能团,各官能团相互协同起到良好增效作用。认为:该共聚物阻垢剂更适用于纺织厂空调循环水系统中,可起到较好的阻垢作用。Aimed at the problem of scaling in equipment pipeline caused by the textile mill air conditioning circulating water,a kind of terpolymer antisludging agent with multi-functional groups was synthesized with water solution free radical polymerization method. Itaconic acid, sodium allysulfonate and hydroxyethyl methylacrylate were used as monomer, ammonium persulfate was taken as initiator and tertiary butanol was selected as molecular weight modifier. The scale inhibition of copolymer against calcium carbonate and calcium sulfate at different water bath temperature were studied. The scale inhibition against calcium carbonate is reached to 98. 25% while the scale inhibition against calcium sulfate is 80. 05%. Compared with polyaspartic acid, the copolymer had better scale inhibition against calcium salt. Moreover, the effect is obviously better than that of polyaspartic acid under the condition of hard water. The structure of copolymer was evaluated with infrared spectroscopy. The results show that the copolymer has multi-functional groups. Each functional group is cooperative to each other and bet- ter synergism is performed. It is considered that the copolymer antisludging agent is suitable to be used in textile mill air conditioning circulating water system. Better scale inhibition can be achieved.
