Decorative panel and method for manufacturing a decorative panel
A decorative panel includes a substrate and a decorative surface. The substrate includes a copolymer of an unsaturated polyester.
1 . A decorative panel comprising a substrate and a decorative surface, wherein said substrate comprises a substrate material with a copolymer of an unsaturated polyester;
wherein the substrate comprises at least first and second lavers comprising the copolymer;
wherein the first layer is provided with a first color different from a second color of the second layer;
wherein the first layer includes an integrated motif made up of a coloration including colored regions;
wherein the integrated motif is present at least at a surface of the substrate, and extends at least 0.5 mm into a thickness of the substrate;
wherein said surface is visible at said decorative surface for at least 30% of an area of said decorative surface;
wherein said integrated motif is locally complemented by means of a printed motif.
2 . The decorative panel of claim 1 , wherein said copolymer is a copolymer of an unsaturated polyester and a vinyl monomer.
3 . The decorative panel of claim 2 , wherein said copolymer is a copolymer of an unsaturated polyester and styrene.
4 . The decorative panel of claim 1 , wherein said unsaturated polyester is a dicyclopentadiene resin or is selected from the group consisting of a resin containing primarily terephthalic acid, a resin containing primarily phthalic anhydride, and a resin containing primarily isophthalic acid.
5 . The decorative panel of claim 1 , wherein said substrate further comprises at least 3 weight parts filler materials per part of the copolymer.
6 . The decorative panel of claim 1 , wherein said substrate further comprises at least 5 wt %, reinforcement fibers.
7 . The decorative panel of claim 1 , wherein said substrate further comprises 0.1 to 10 wt % of a metal salt, and/or 0.1 to 10 wt % of an organic peroxide.
8 . The decorative panel of claim 1 , wherein said panel is provided with a lowered edge region obtained by machining away a portion of a top edge of the panel to create a beveled surface, wherein the beveled surface is limited to the first layer and has the same color variations as the surface of the substrate.
9 . A method for manufacturing a decorative panel, wherein said decorative panel comprises a substrate and a decorative surface,
wherein said method comprises at least a step of providing a substrate with a substrate material comprising a copolymer of an unsaturated polyester;
wherein said method further comprises the step of providing a decorative surface to said substrate;
wherein the substrate comprises at least first and second layers comprising the copolymer;
wherein the first layer is provided with a first color different from a second color of the second layer;
wherein the first layer includes an integrated motif made up of a coloration including colored regions;
wherein the integrated motif is present at least at a surface of the substrate, and extends at least 0.5 mm into a thickness of the substrate;
wherein a printed motif is formed on the surface of said substrate;
wherein said surface remains visible at said decorative surface for at least 30% of an area of said decorative surface;
wherein said integrated motif is locally complemented by means of said printed motif.
10 . The method of claim 9 , wherein said step of providing a substrate comprises:
providing a mixture by mixing a resin selected from the group consisting of a dicyclopentadiene resin, a resin containing primarily terephthalic acid, a resin containing primarily phthalic anhydride, and a resin containing primarily isophthalic acid with at least a vinyl monomer; and
shaping and curing said mixture into at least a part of said substrate.
11 . The method of claim 10 , wherein said mixture further comprises filler materials, reinforcement fibers, metal salt and/or organic peroxide.
12 . The method of claim 10 , wherein said shaping and curing said mixture comprises pressing said mixture at a pressure of 1 MPa or above.
13 . The method of claim 10 , wherein said shaping and curing comprises forming said part of said substrate to have a board shape with a decorative relief in at least one of the major surfaces of said board.
