Title
(EN) Wound dressing having a polyurethane foam layer and a cover layer made of thermoplastic polymer
(ZH) 具有聚氨酯泡沫体层和由热塑性聚合物制成的覆盖层的伤口敷料
Abstract
(EN) The present invention relates to a layer composite, suited as a wound dressing, comprising a foam layer (10) and a cover layer (20), wherein the cover layer (20) comprises thermoplastic polymer, preferably polyurethane, and is at least partially directly connected to the foam layer (10), and wherein the foam layer (10) comprises a polyurethane foam which is obtained by foaming and drying a composition comprising an aqueous, anionically hydrophilized polyurethane dispersion (I). The foam can be stabilized using ethylene oxide/propylene oxide block copolymers. The invention further relates to a method for producing a layer composite of said kind and to the use thereof, for example as a wound dressing.
(ZH)

本发明涉及适合作为伤口敷料的、包括泡沫体层(10)和覆盖层(20)的层状复合材料,其中覆盖层(20)包括热塑性聚合物,优选聚氨酯,并且至少部分地直接连接到该泡沫体层(10)上,且其中该泡沫体层(10)包括由含有阴离子亲水化聚氨酯水分散体(I)的组合物进行发泡和干燥所获得的聚氨酯泡沫体。该泡沫体能够用环氧乙烷/环氧丙烷嵌段共聚物来稳定化。本发明进一步涉及生产该类型的层状复合材料的方法和涉及它例如作为伤口敷料的用途。
