TRANSPARENT HEAT PROTECTION FOIL AND PROCESS FOR PRODUCING THE SAME |
摘要 |
Known heat protection foils have several metal layers which reflect thermal radiation and let light through. Systems of alternating metal and non-metal layers are also known. Their disadvantage is that in particular the metal layers are subject to corrosion. The outermost protection layer is not sufficiently scratch-resistant either. Consequently, such heat protection foils may hardly be used on the outer side of glass panes. They are not weather-resistant either. According to the invention, a selectively reflecting system of alternating layers is applied on the plastic foil, together with an anti-abrasive layer. The system of alternating layers consists of corrosion-resistant metal, oxide, nitride and/or oxinitride layers. The anti-abrasive layer consists of an at least 1 mu m thick, highly transparent and homogeneous amorphous oxide layer with high packing density and a micro-hardness of at least 4 Gpa. These layers are applied by high-speed sputtering by means of a dual magnetron. The anti-abrasive layer is applied by plasma- and/or ion-assisted high-speed vapour deposition. This heat protection foil may be applied on the outer side of window panes of buildings and vehicles. |
