Flexible decorative laminate
A flexible decorative laminate including a core obtained by impregnating a carrier with a thermosetting resin associated with a decorative layer and provided with a protective layer. The carrier includes cellulose and glass fibers which are bound to each other by a plasticizer.
1. A flexible decorative laminate (I) comprising:
a core ( 1 ) consisting of a support impregnated with a thermosetting resin; and a decorative layer ( 2 ) joined with the core ( 1 );
wherein the support consists essentially of at least about 60% by weight cellulose fibers and 10-20% by weight glass fibers connected together by about 10-20% by weight of a plasticizer.
2. The decorative laminate (I) according to claim 1 , wherein the thermosetting resin comprises a phenolic resin, or a phenol/formaldehyde mixture obtained in a basic reaction medium.
3. The decorative laminate (I) according to claim 2 , wherein a weight of the thermosetting resin is 34-40% of the total weight of the impregnated core.
4. The decorative laminate (I) according to claim 1 , wherein the support has a grammage of 100-150 g/m 2 .
5. The decorative laminate (I) according to claim 1 , wherein the total weight of the glass fibers, cellulose fibers and plasticizer is at least 98% of the total weight of the support.
6. The decorative laminate (I) according to claim 1 , wherein combustion of the laminate releases a calorific potential of less than 4.5 MJ/m 2 .
7. The decorative laminate (I) according to claim 1 , wherein at room temperature the decorative laminate can be shaped to radii of curvature of 11 mm or less, and by heating to a temperature greater than or equal to 80° C., to radii of curvature of 2.8 mm or less.
8. The decorative laminate (I) according to claim 1 , wherein thermal expansion of the laminate, over a temperature range of 20-100° C., is between 0 and 500 ppm (10 −6 meter).
9. The decorative laminate (I) according to claim 1 , wherein the laminate has a thickness between 0.2 and 0.4 mm.
10. The decorative laminate (I) according to claim 1 , wherein the core ( 1 ) is a single layer.
11. The decorative laminate (I) according to claim 1 , wherein the glass fibers have a length greater than or equal to 4 mm.
12. The decorative laminate (I) according to claim 1 , wherein the cellulose fibers are bleached, raw or recycled cellulose fibers, or a mixture thereof.
13. The decorative laminate (I) according to claim 1 , wherein the plasticizer is starch.
14. The decorative laminate (l) according to claim 1 , wherein the decorative laminate has a specific gravity of greater than or equal to 1.35.
15. A flexible decorative laminate (I) comprising:
a core ( 1 ) consisting of a support impregnated with a thermosetting resin, wherein the support consists essentially of at least about 60% by weight cellulose fibers and 10-20% by weight glass fibers connected together by about 10-20% by weight of a plasticizer
a decorative layer ( 2 ) joined with the core ( 1 ); and
a protective covering ( 3 ) covering the decorative layer.
16. A flexible decorative laminate (I) comprising:
a core ( 1 ) consisting of a support impregnated with a thermosetting resin, wherein the support consists essentially of at least about 60% by weight cellulose fibers and glass fibers connected together by about 10-20% by weight of a plasticizer, the glass fibers have a length greater than or equal to 4 mm, and an amount of the glass fibers is 10-20% of the total weight of the support; and
a decorative layer ( 2 ) joined with the core ( 1 ); and
a protective covering ( 3 ) covering the decorative layer.
