The use of an internally plasticized vinyl chloride film and a fabric backing, preferably a nonflame retardant fabric backing, as the substrate in a vinyl film/substrate laminate yields a product having a lower rate of smoke generation when burned than is produced by a conventional laminate of an externally plasticized vinyl film and a fabric backing. The internally plasticized vinyl chloride resin used in the vinyl film of the laminate of this invention may be a copolymer comprising from about 50% to about 85%, by weight, vinyl chloride, from about 3% to about 47%, by weight, of a C6-C10 alkyl acrylate, and from about 47% to about 3%, by weight, of a bis(hydrocarbyl)vinylphosphonate. The vinyl film/substrate laminate of the present invention is useful as an upholstery product.
在乙烯基薄膜/基材层压制品中,使用内部塑化的氯乙烯薄膜和织物衬底(最好是非阻燃织物衬底)作为基材,可获得燃烧时产生烟雾的速率低于外部塑化的乙烯基薄膜和织物衬底的传统层压制品。本发明层压板的乙烯基薄膜中使用的内部增塑的氯乙烯树脂可以是一种共聚物,按重量计,包括约 50% 至约 85% 的氯乙烯、约 3% 至约 47% 的 C6-C10 烷基丙烯酸酯和约 47% 至约 3% 的双(烃基)乙烯基膦酸酯。本发明的乙烯基薄膜/基材层压板可用作室内装饰产品。
