Floor panel for outdoors
The present invention relates to floor panels for outdoor use, which front side is provided with a decorative—respectively protective layer and which comprises at its sides coupling means inform of groove and tongue elements. The material of the carrier plate is thereby MDF or HDF board of acetylated wood, a fiber cement board or is based on polyvinylchloride and the decorative—respectively protective layer consisting of a radiation cured acrylate-containing film or a polymeric layer with hardness gradient, wherein the hardness of the polymeric layer decreases in particular continuously with increasing depth seen from the surface of the polymeric layer.
1. A floor panel for outdoor use, comprising
a carrier plate with a front side and rear side,
a radiation cured acrylate-containing film provided on the front side of the carrier plate,
a polyurethane adhesive interposed between the radiation cured acrylate-containing film and the front side of the carrier plate, the polyurethane adhesive adhering the radiation cured acrylate-containing film to the front side of the carrier plate, and
a polymerizable printing ink, wherein
the polymerizable printing ink and the acrylate-containing film are radiation cured together, and
wherein the carrier plate has sides provided with groove and tongue elements that allow connecting multiple similar panels in directions parallel to the front side as well as perpendicular to the front side by form fit, wherein
the material of the carrier plate is chosen from the group consisting of:
MDF or HDF-board of acetylated wood;
Fiber cement board;
Polyvinylchloride.
2. The floor panel for outdoor use according to claim 1 , wherein there is provided a glass non-woven, a waterproof film, or an acrylate coating on the rear side of the fiber cement board.
3. The floor panel for outdoor use according to claim 1 , wherein the film is imprinted with a decor.
4. The floor panel for outdoor use according to claim 1 , wherein the front side of the carrier plate is provided with an undercoat under the film.
5. The floor panel for outdoor use according to claim 4 , wherein the undercoat is imprinted with a printing ink forming a decor.
6. The floor panel for outdoor use according to claim 5 , wherein the printing ink comprises at least one of a polymerizable acrylate and n-vinylcaprolactam.
7. The floor panel for outdoor use according to claim 6 , wherein the printing ink comprises a polymerizable acrylate and n-vinylcaprolactam with a weight proportion (%) of the printing ink from 2 to 50%.
8. The floor panel for outdoor use according to claim 4 , wherein the undercoat is based on an aqueous acrylate-system.
9. The floor panel for outdoor use according to claim 4 , wherein the undercoat provides a thickness between 5 and 300 μm.
10. The floor panel for outdoor use according to claim 1 , wherein the panel is not provided with abrasion-resistant particles.
11. The floor panel for outdoor use according to claim 1 , wherein the film is a paper film and is impregnated with acrylate.
12. The floor panel for outdoor use according to claim 1 , wherein the film contains additives in form of at least one of UV-absorbents and radical interceptors.
13. The floor panel for outdoor use according to claim 1 , wherein the film contains additives in form of UV-absorbents in such an amount, to achieve at least a 99% UV-blocking.
14. The floor panel for outdoor use according to claim 1 , wherein edges the front side of the panel have bevels so that a V- or U-shaped groove is formed between the panel and an adjacent panel.
15. The floor panel for outdoor use according to claim 1 , wherein the carrier plate provides a thickness between 3 and 20 mm.
16. A method for making a floor covering for an outdoor area comprising the steps:
providing a plurality of panels according to claim 1 ;
installing the panels in an outdoor area by interconnecting the panels.
17. The method according to claim 16 , wherein the installing step includes installing the panels on a layer of gritting material.
18. The method according to claim 17 , wherein the gritting material comprises 90% quantity fraction particle size from 2 to 32 mm.
19. An outdoor area comprising a plurality of panels according to claim 1 that are interconnected by the tongue and groove elements.
