Abstract

An edge trim for pieces of furniture, including a meltable layer, is described. The molecular structure of the meltable layer contains both polar and non-polar parts. By way of a non-limiting example, an edge trim for pieces of furniture having an exposed edge of wooden or wood substitute material is described, comprising a molten layer and a structural layer, wherein the structural layer and the molten layer are connected in an adhesive bond, wherein the molten layer is made of a material that is chemically modified such that polar and non-polar components are found in a single molecular structure, wherein the molten layer contains energy absorbing additives, wherein the energy absorbing additives of the molten layer are selected from the group consisting of metal oxides, metal phosphates, metal salts of organic anions and combinations thereof.

Claims (27)

1. An edge trim for pieces of furniture having an exposed edge of wooden or wood substitute material, comprising:

a meltable layer; and

a structural layer;

wherein the structural layer and the meltable layer are connected in an adhesive bond;

wherein the meltable layer is made of a material that is chemically modified such that polar and non-polar components are found in a single molecular structure;

wherein the meltable layer is based on a material from which the structural layer is produced;

wherein the structural layer is produced from polypropylene;

wherein the meltable layer is based on polypropylene;

wherein the meltable layer contains energy absorbing additives;

wherein the energy absorbing additives of the meltable layer are selected from the group consisting of copper phosphates, tin phosphates, iron phosphates, nickel phosphates, molybdenum phosphates, cobalt phosphates, manganese phosphates, antimony phosphates and combinations thereof.

2. The edge trim according to claim 1 , wherein the copper phosphates include copper hydroxyphosphate in a weight fraction of 0.5-5%.

3. The edge trim according to claim 1 , wherein the structural layer and the meltable layer are coextruded.

4. The edge trim according to claim 1 , wherein the material of the meltable layer has a lower melting point than the material of the structural layer.

5. The edge trim according to claim 1 , wherein the polypropylene is a copolymer, a grafted copolymer or a maleic anhydride grafted polypropylene.

6. The edge trim according to claim 1 , wherein the meltable layer of the edge trim defines an underside or abutting side thereof.

7. The edge trim according to claim 1 , wherein the structural layer forms a top layer of the edge trim, which defines a top side or visible side thereof.

8. The edge trim according to claim 7 , wherein the top side comprises a décor.

9. The edge trim according to claim 1 , wherein the meltable layer forms a bottom layer of the edge trim, which defines a bottom side or installation side thereof.

10. The edge trim according to claim 1 , wherein the structural layer has a thickness of 0.8 to 5.0 mm.

11. The edge trim according to claim 1 , wherein the meltable layer has a thickness of 0.1 to 1.5 mm.

12. A piece of furniture having an exposed edge with an edge trim according to claim 1 , wherein a bottom side of the edge trim is connected with a full surface with an edge of the piece of furniture in a material bonding manner.

13. The piece of furniture according to claim 12 , wherein a material comprising the piece of furniture is selected from the group consisting of wood materials, wood substitutes and combinations thereof.

14. The piece of furniture according to claim 13 , wherein the material of the structural layer is selected from the group consisting of wood materials, wood substitutes, metals, glasses, plastics, stones, ceramics and combinations thereof.

15. The piece of furniture according to claim 13 , wherein a bottom side of the piece of furniture has an average roughness R a greater than 10 μm.

16. A piece of furniture having the edge trim according to claim 1 attached to an exposed edge of wooden or wood substitute material of the piece of furniture, wherein the exposed edge is an end face of the piece of furniture, wherein due to a denser, stronger compression of wood particles or chips nearer to a surface of the piece of furniture as viewed in cross section in a middle region of the end face, a roughness of the middle region is larger than in at least one adjacent denser edge region, and wherein a bottom side of the edge trim is connected with a full surface with the exposed edge of the piece of furniture in a material bonding manner.

17. The piece of furniture according to claim 16 , wherein the piece of furniture is a chipboard, wherein a width of the middle region is ⅓ of a width of the end face, and wherein an average roughness R a in the middle region is more than 200 microns.

18. The piece of furniture according to claim 16 , wherein the piece of furniture is a chipboard, wherein a width of the middle region is ⅓ of a width of the end face, and wherein an average roughness R a in the middle region is more than 500 microns.
