Au-Ag线的银蒸汽涂膜的组成是:一层树脂膜,一层用真空蒸汽沉积法直接或通过内涂层在树脂膜上生成的银蒸汽涂层,以及在银蒸汽涂层上生成的一保护层。内涂层和保护层含有一种防腐剂,这种防腐剂主要是用一种可汽化的防锈剂混合并弥散于两涂层上的。 最好的树脂膜是聚酯、聚丙烯或聚酰胺等,防护层最好是丙烯树脂、苯代树脂或可以热塑成形的 The composition of the silver vapor coating of the Au-Ag wire is: a resin film, a silver vapor coating formed on the resin film by vacuum vapor deposition directly or through the undercoat, and a silver vapor coating formed on the silver vapor coating A protective layer. The inner and outer layers contain a preservative that is primarily mixed and dispersed on both layers with a vaporizable rust inhibitor. The most preferred resin film is polyester, polypropylene, polyamide or the like. The protective layer is preferably acrylic, benzophenone or thermoplastic
