Composite panels with sun shading and thermal insulation

Abstract

The invention relates to a composite panel with solar shading and thermal insulation functions, comprising an outer panel (1) with an outer surface (I) and an inner surface (II), an inner panel (2) with an outer surface (III) and an inner surface (IV) ) and a thermoplastic intermediate layer (3), the composite panel comprising at least: - a sunshade coating (4) at least on the inner face (II), on the outer face (III) or in the thermoplastic intermediate layer (3), and - a thermal barrier coating (5) on the inner face (IV), wherein the sun protection coating (4) comprises at least one functional layer containing at least silver, and wherein the thermal barrier coating (5) comprises at least one functional layer , which contains at least one metal from the group consisting of niobium, tantalum, molybdenum and zirconium.

Description

technical field

[0001] The invention relates to a composite panel with sunshade and thermal insulation functions, a method for the production of the composite panel and the use of the composite panel. Background technique

[0002] In summer, the interior of a motor vehicle heats up rapidly due to high ambient temperatures and strong direct sunlight. In order to achieve an acceptable thermal comfort for the passengers, the air in the interior can be conditioned, but this leads to increased fuel consumption and the associated greenhouse gases, especially CO 2 increased emissions.

[0003] Panels with sunshade functions are also known. The pane is provided with a coating which reflects part of the solar radiation (in particular IR radiation) and thus reduces the heating of the vehicle interior. Such coatings are known, for example, from documents EP 2 268 588 A2, EP 1 993 829 A2 and EP 1 744 995 A2. However, the plates still heat up at high ambient temperatures and radiate ...
