Embodiment Construction

[0059] The described embodiment relates to a composite material V according to the invention having a high reflectivity, especially in the solar wavelength range. It can preferably be arranged to reflect optical radiation, ie electromagnetic radiation in the wavelength range from 100 nm to 1 mm.

[0060] The composite material V comprises, in particular, a deformable strip-shaped substrate 1 made of aluminum, an intermediate layer 2 on one side A of the substrate 1 and an optically active multilayer system applied over the intermediate layer 2 3.

[0061] The total light reflectance determined according to DIN 5036 part 3 on side A of the optical multilayer system 3 is greater than 90%, preferably at least 95%, particularly preferably at least 97%.

[0062] The composite material V can preferably be configured with a width of up to 1600 mm, preferably 1400 mm, and, including any layers present on its rear side B, a thickness D of approximately 0.2 mm to 1.7 mm, preferably app...

Abstract

The invention relates to a reflective composite material (V) having a carrier (1) consisting of aluminum, having an interlayer (2) which is present on a side (A) on the carrier (1) and is composed ofa varnish, and having an optically active multilayer system (3) which has been applied atop the interlayer (2) and consists of at least three layers, wherein the upper layers (4, 5) are dielectric and / or oxidic layers, and the lowermost layer (6) is a metallic layer which consists of silver and forms a reflection layer (6). To increase the aging resistance, it is proposed that the interlayer (2) comprise an organic layer-forming varnish or be formed entirely from such a varnish that has been cured by an ionic photopolymerization and crosslinking or that has been cured after UV irradiation by free-radical photopolymerization and crosslinking.

Description

technical field [0001] The invention relates to a reflective composite material with a substrate made of aluminum, with an intermediate layer of lacquer on the substrate and with an optically active multilayer material applied above the intermediate layer. A layer system comprising at least three layers, wherein the upper layer is a dielectric layer and / or an oxide layer and the lowermost layer is a metal layer made of silver, which forms the reflective layer. Furthermore, the invention relates to a method for producing such a reflective composite. Background technique [0002] Similar composites as surface-finished aluminum strips have been -silver The name is widely used in lighting technology, daylight systems and decorative applications. In this case, surface treatments are used to better protect the sensitive aluminum surfaces and to increase light reflectivity. The surface finishing process consists of two distinct processes, which can be operated consecutively, ...
