Abstract:

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 fabric-reinforced 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 flame-retardant 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.

Key words: polyvinyl chloride/polyester composite, flame-retardancy, limit oxygen index, light transmittance
