摘　　要：本研究采用聚氯乙烯(PVC)和聚酯纤维(PET)作为原料,通过热压贴合工艺制得了PVC/PET柔性复合材料。在PVC涂层膜中添加不同的阻燃剂和抗紫外剂,发现氧化锑-硼酸锌协同作用的阻燃体系表现出良好的阻燃效果,当添加5 phr时,可将涂层布的极限氧指数提高至28.7%。此外,该阻燃体系还具有抑制烟雾生成的效果,使烟密度降低了35.2%。在抗紫外方面,抗紫外剂UV-531的效果与UV-234效果相当,但在抗热迁出方面表现更加优异,因此选择UV-531作为PVC/PET柔性复合材料的抗紫外剂。在涂层膜和基布复合时,添加3.0 g/m2的胶黏剂可将材料的剥离强度提高至28.89 N/5 cm,同时不影响其他性能,从而延长PVC/PET柔性复合材料的使用寿命。Polyvinyl chloride(PVC)and polyester fibre(PET)were used as raw materials to form PVC/PET flexible composites by a hot press lamination process.By adding different flame retardants and anti-UV agents to the PVC coated film,it was found that the antimony oxide-zinc borate synergistic flame retardant system exhibited good flame retardant effect,which increased the ultimate oxygen index of the coated fabric to 28.7%when 5 phr was added.In addition,the flame retardant system also had the effect of inhibiting smoke generation,resulting in a 35.2%reduction in smoke density.In terms of UV resistance,UV-531 anti-UV agent is comparable to UV-234,but performs even better in terms of resistance to heat migration.Therefore,UV-531 was chosen as the anti-UV agent for PVC/PET flexible composites.The addition of 3.0 g/m2 of adhesive during the lamination of the coated film and the base fabric increases the peel strength of the material to 28.89 N/5 cm without affecting other properties,thus extending the service life of the PVC/PET flexible composite.
