Abstract
The wall/ceiling covering has a reflectivity for infrared radiation of more than 60% and comprises a substrate of paper or plastic or tile material, a discontinuous thin metal layer, a veneer protective layer thereon and a veneer coating which comprises a binder and at least one coloring agent, and which is substantially transparent in the wavelength range of 4 to 20 .mu.m.
Claims18
A heat-reflecting covering material for walls and ceilings, having a reflectivity for infrared radiation of more than 60%, comprising a laminate of
- (a) a base substrate material made of wood paper having a weight range of 80 to 300 gms/m.sup.2 ;
- (b) an adhesive lining of a lamination glue 5 to 30 .mu.m in thickness on said base substrate material;
- (c) a thin layer of a moisture and alkali resistant paper having a weight range of 40 to 100 gms/m.sup.2 thereon;
- (d) a clay coating of 2 to 30 .mu.m thickness;
- (e) a base coat of priming layer in a thickness of 1 to 20 .mu.m;
- (f) a discontinuous aluminum layer 10 to 1000 nanometers in thickness;
- (g) a thin veneer protection layer in a thickness of 0.2 to 10 .mu.m;
- (h) a white base cover layer in a thickness of 1 to 20 .mu.m providing the neutral white background;
- (i) a finishing veneer coating in a thickness of 0.2 to 2 .mu.m and comprising a binder and at least one coloring agent, said veneer being substantially transparent in the wavelength range of 4 to 20 .mu.m;
- and
- (j) a molecular layer of dust and water repellent material in the thickness of 0.05 to 1.0 .mu.m.
A tile provided with a covering material having a reflectivity for infrared radiation of more than 60%, said covering material comprising a thin discontinuous layer of aluminum in a thickness of 5 .mu.m to 1 millimeter and a veneer layer comprising a binder and at least one coloring agent on said aluminum layer in a thickness of 0.2 to 10 .mu.m, said veneer layer being substantially transparent in the wavelength range of 4 to 20 .mu.m.
A process of producing a covering material, comprising the sequential steps of
- (a) providing a base substrate material made of wood paper having a weight range of 80 to 300 gms/m.sup.2 ;
- (b) applying an adhesive lining of a lamination glue 5 to 30 .mu.m in thickness on said base material;
- (c) adhering a thin layer of moisture and alkali-resistant paper having a weight range of 40 to 100 gms/m.sup.2 to said adhesive lining;
- (d) applying a clay coating of 2 to 30 .mu.m thickness on top of said moisture and alkali resistant paper;
- (e) applying a base coat of priming layer in a thickness of 1 to 20 .mu.m on said clay coating;
- (f) depositing a discontinuous aluminum layer 10 to 1000 nanometers in thickness on said priming layer;
- (g) applying a thin veneer protection layer in a thickness of 0.2 to 10 .mu.m on said aluminum layer;
- (h) applying a white base cover layer in a thickness of 1 to 20 microns providing the neutral white background on said veneer protection layer;
- (i) applying to said white base a finishing veneer coating substantially transparent in the wavelength range of 4 to 20 .mu.m and comprising a binder and at least one coloring agent;
- (j) applying a molecular layer of dust and water repellent material in a thickness of 0.05 to 1.0 .mu.m to said finishing veneer coating.
A process of producing a tile with a covering material thereon, said covering material having a reflectivity for infrared radiation of more than 60% by coating a tile with a thin, discontinuous layer of aluminum in a thickness of 5 .mu.m to 1 millimeter and then with a veneer layer comprising a binder and at least one coloring agent in a thickness of 0.02 to 10 .mu.m, said veneer layer being substantially transparent in the wavelength range of 4 to 20 .mu.m.
