Rear-illuminable aircraft interior component
View Patent ↗The present invention relates to a rear-illuminable aircraft interior component consisting of a transparent or translucent thermoplastic, a translucent varnish layer disposed on the latter and a decorative varnish layer disposed on the translucent varnish layer, as well as the use of a rear-illuminable aircraft interior component of this kind as a rear-illuminable aircraft window ring.
1. A rear-illuminable aircraft interior component consisting of a transparent or translucent thermoplastic, a translucent varnish layer disposed on the transparent or translucent thermoplastic and a decorative varnish layer disposed on the translucent varnish layer, in which the translucent varnish layer is obtained by applying a translucent, solvent-containing two-component polyurethane varnish which comprises an inorganic pigment and a refractive component, wherein the inorganic pigment has a particle size in the range from 0.2 to 1.0 μm and the refractive component has a particle size in the range from 4.0 to 5.5 μm such that the refractive component has a larger particle size than the inorganic pigment in the translucent varnish layer wherein the transparent or translucent thermoplastic is a polyphenylsulphone thermoplastic and the decorative varnish layer is obtained by applying a solvent-containing two-component polyurethane varnish.
2. The rear-illuminable aircraft interior component according to claim 1 , in which the translucent, solvent-containing two-component polyurethane varnish also comprises a glossy pigment.
3. The rear-illuminable aircraft interior component according to claim 2 , in which the glossy pigment has a particle size of less than 60 μm.
4. The rear-illuminable aircraft interior component according to claim 2 , in which the glossy pigment is mica.
5. The rear-illuminable aircraft interior component according to claim 1 , in which the inorganic pigment has a refractive index in the range from 2.5 to 3.1.
6. The rear-illuminable aircraft interior component according to claim 1 , in which the pigment is titanium dioxide.
7. The rear-illuminable aircraft interior component according to claim 1 , in which the refractive component has a refractive index of 1.5 to 2.1.
8. The rear-illuminable aircraft interior component according to claim 1 , in which glass particles are used as the refractive component.
9. The rear-illuminable aircraft interior component according to claim 1 , in which the decorative varnish layer is obtained by applying a solvent-containing metallic two-component-polyurethane varnish which comprises a metal pigment.
10. The rear-illuminable aircraft interior component according to claim 9 , in which the solvent-containing metallic two-component polyurethane varnish also comprises a pearlescent pigment.
11. The rear-illuminable aircraft interior component according to claim 10 , in which the pearlescent pigment has a particle size in the range from 10 to 60 μm.
12. The rear-illuminable aircraft interior component according to claim 10 , in which the pearlescent pigment is mica.
13. The rear-illuminable aircraft interior component according to claim 9 , in which the metal pigment has a particle size of less than 25 μm.
14. The rear-illuminable aircraft interior component according to claim 9 , in which the metal pigment is selected from the group consisting of aluminium, copper, gold bronze, silver, gold, cobalt, titanium, tin and mixtures thereof.
15. The rear-illuminable aircraft interior component according to claim 1 , in which the decorative varnish layer is obtained by applying a solvent-containing two-component polyurethane varnish which comprises an inorganic or organic pigment.
16. The rear-illuminable aircraft interior component according to claim 1 , in which the aircraft interior component is an aircraft window ring.
17. The rear-illuminable aircraft interior component according to claim 16 , wherein the transparent or translucent thermoplastic is shaped from a sheet so as to define the shape of the aircraft window ring.
18. A process of using a rear-illuminable aircraft interior component in an aircraft having a window, the process comprising:
providing a rear-illuminable aircraft interior component consisting of a transparent or translucent thermoplastic, a translucent varnish layer disposed on the transparent or translucent thermoplastic and a decorative varnish layer disposed on the translucent varnish layer, in which the translucent varnish layer is obtained by applying a translucent, solvent-containing two-component polyurethane varnish which comprises an inorganic pigment and a refractive component wherein the transparent or translucent thermoplastic is a polyphenylsulphone thermoplastic and the decorative varnish layer is obtained by applying a solvent-containing two-component polyurethane varnish; and
installing the rear-illuminable aircraft interior component around the window to form an aircraft window ring,
wherein the inorganic pigment has a particle size in the range from 0.2 to 1.0 μm and the refractive component has a particle size in the range from 4.0 to 5.5 μm such that the refractive component has a larger particle size than the inorganic pigment in the translucent varnish layer.
