Formula Study on Antibacterial and Cold-Resistant PVC Shower Hose
Under the action of cross-linking agent ditert-butyl-peroxyisopropyl benzene(BIPB),the antibacterial agent polyhexamethylene biguanide hydrochloride(PHMG)was bonded to the molecular chain of polyvinyl chloride(PVC)in the form of chemical bond;At the same time,an antibacterial and cold resistant PVC material was prepared by combining adipic acid polyester and powdered nitrile rubber(PNBR),and a PVC composite hose was trial produced.The test results showed that the antibacterial rate of PVC shower hose produced with this formula against Staphylococcus aureus and Escherichia coli exceeded 99.5%,not less than 98%after aging test;At low temperature of 0℃,the Shore hardness is 9 A lower than that of phthalate plasticizer(DOP)formula,and the tensile strength is 2.9 MPa higher than that of low molecular weight cold resistant plasticizer dioctyl adipate(DOA).
