摘要：
Disclosed are carpet products comprising at least one flexible substrate and at least one coating and/or adhesive layer associated with the at least one flexible substrate. The coating and/or adhesive layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a selected ethylene content or glass transition temperature. It is also preferably substantially free of cross-linkable co-monomer moieties which generate formaldehyde upon curing and preferably has a particle size, dw, ranging from about 50 to about 500 nm. The carpet product is substantially free of polyvinyl chloride and bitumen and exhibits a Class B1 flame-retardancy in accordance with DIN 4102-14, corresponding to a critical heat flux of ≧about 4.5 kW/m2.
摘要（中）：
公开了包含至少一个柔性基底和与至少一个柔性基底相关联的至少一个涂层和/或粘合剂层的地毯产品。 涂层和/或粘合剂层由水性组合物形成，该组合物包含：A）乳化剂稳定的乙酸乙烯酯/乙烯（VAE）乳液共聚物分散体和B）至少一种选自颗粒无机化合物和颗粒状塑料材料的颗粒填料。 共聚物分散体中的乙酸乙烯酯/乙烯共聚物具有选定的乙烯含量或玻璃化转变温度。 还优选基本上不含可固化的共聚单体部分，其在固化时产生甲醛，优选具有约50至约500nm范围内的粒度dw。 地毯产品基本上不含聚氯乙烯和沥青，并且符合DIN 4102-14的B1类阻燃性，对应于> = 4.5kW / m 2的临界热通量。
