Embodiment Construction

[0070] figure 1 Shown is a section through the design of the composite panel according to the invention with solar shading and thermal insulation functions. The composite panel comprises an outer panel 1 and an inner panel 2 , which are connected to one another via a thermoplastic intermediate layer 3 . Composite panels have about 1m 2 and set as the roof panel of a passenger car, wherein the outer panel 1 faces the external environment and the inner panel 2 faces the vehicle interior space. The outer panel 1 has an outer face (I) and an inner face (II). The inner panel 2 has an outer face (III) and an inner face (IV). The outer faces (I) and (III) face the external environment, and the inner faces (II) and (IV) face the vehicle interior space. The inner face (II) of the outer panel 1 and the outer face (III) of the inner panel 2 face each other. The outer pane 1 and the inner pane 2 contain soda lime glass and each have a thickness of 2.1 mm. The thermoplastic intermedi...

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 ...
