摘要
为解决聚氯乙烯(PVC)/聚酯(PET)复合材料阻燃性能相对于纯聚氯乙烯、聚酯阻燃性能下降的问题,在聚氯乙烯/环己酮溶液中添加5种不同阻燃机制的阻燃剂,利用自动涂膜机将其涂覆在聚酯机织物上制备得到极限氧指数大于28%可应用于建筑领域的聚氯乙烯/聚酯复合材料。借助极限氧指数测试仪、接触角测试仪、可见光透过率测试仪对PVC/PET复合材料的性能进行表征。结果表明:主要成分为烯丙基苯并三唑的阻燃剂对PVC/PET复合材料有良好的阻燃效果,当PVC涂层中阻燃剂质量分数为10%,涂层厚度为1. 35 mm时,其透光率为5%,极限氧指数为30%,可满足建筑膜材料的使用要求。
In order to solve the problem that the flame retardant performance of polyvinyl chloride(PVC)/polyester(PET)composites was lower than that of PVC and polyester.The PET fabricreinforced PVC composites with the limit oxygen index grenter 28%were prepared by adding different retardants in the PVC/cyclohexanone solution,and coating an polyester fabric.The properties of flame retardant,light transmission and self-cleaning of PVC/PET composites were evaluated by a limiting oxygen index tester,a contact angle tester and a visible light transmittance tester,respectively.The results demonstrate that flant redardant maihly contaraing allyl benzotriazole(WSA-105)has good flameretardant performance for PVC/PET composites.Moreover,the effects of different concentrations of WSA-105 and different thicknesses of PVC coating on limiting oxygen index,contact angle and light transmittance of the PVC/PET fabric composite were studied,and the results indicate that the light transmittance is 5%and the limiting oxygen index is 30% with the flame retardant concentration of 10% and the coating thickness of 1.35 mm for construction membrane materials.
