摘　　要：以3-氨丙基三乙氧基硅烷、双氰胺及五氧化二磷等为原料,合成了具有抗菌阻燃多功能的化合物CF,用红外光谱对化合物CF进行了结构表征,采用轧-烘-焙工艺,用合成的阻燃剂对棉织物进行整理,研究了整理后棉织物的阻燃及抗菌性能.结果表明:棉织物经CF整理,其阻燃性能随CF用量的增大而增大,当CF用量为20g/L时,极限氧指数为32.3%,损毁长度为3.4cm,阴燃时间和续燃时间均为0s,达到了最好的阻燃效果,CF整理的棉织物对大肠杆菌的抑菌带宽度为1.9mm,抑菌率为97%,对金黄葡萄球菌的抑菌带宽度为1.6mm,抑菌率为96%,抗菌性能较好.Compound CF with anti-bacterial and flame-retardant properties was synthesized from 3-aminopropyl triethoxysilane,dicyandiamide and phosphorus pentoxide.The structure of compound CF was characterized by infrared spectroscopy.Cotton fabric was treated by pad-bake-bake process and synthesized flame retardant.The flame-retardant and anti-bacterial properties of finished cotton fabric were studied.The results showed that the flame retardancy of cotton fabric treated with CF increased with the increase of CF dosage.When CF dosage was 20 g/L,the limiting oxygen index was 32.3%,the damage length was 3.4 cm,the smoldering time and the continuation time were both 0 s.The best flame retardant effect was achieved.The antibacterial band width of CF treated cotton fabric to Escherichia coli is 1.9 mm,the antibacterial rate is 97%,the antibacterial band width to Staphylococcus aureus is 1.6 mm,the antibacterial rate is 96%,and the antibacterial performance is good.
