摘　　要：利用异噻唑啉酮类抗菌剂开发抗菌聚丙烯,研究了造粒温度、注射温度、紫外光老化,变色抑制剂等对抗菌聚丙烯黄色指数和色差的影响,并通过热失重/红外同步热分析仪对异噻唑啉酮的热稳定性进行了分析。结果表明:当耐变色抗菌聚丙烯中4,5-二氯-2-正辛基-4-异噻唑啉-3-酮含量达到0.25%(w)时,试样在50℃水煮16 h后,对大肠杆菌和金黄色葡萄球菌的抗菌率大于99%。Isothiazolinone antibacterial agents were used to develop antibacterial polypropylene.The effect of pelletizing temperature,mold injection temperature,ultraviolet aging,and discoloration inhibitor on the yellow index and color difference of antibacterial polypropylene were observed.The thermal stability of Isothiazolinone was observed by thermal gravimetric/infrared simultaneous thermal analyzer.The results show that the antibacterial rates of the sample on Escherichia coli and Staphylococcus aureus reach 99%after the hot water treatment at 50℃for 16 hours when the content of 4,5-dichloro-2-n-octyl-4-isothiazoline-3-ketone is 0.25%(w).
