Decorative laminate and method for manufacturing same
A decorative laminate includes a decorative layer composed of a resin impregnated decorative sheet and a core layer composed of plural resin impregnated core sheets of core paper, wherein an exposed sheet at a bottom of the decorative laminate is subjected to a parchment treatment.
1. A decorative laminate constructed from plural layers bonded under heat and pressure to form a unitary structure, comprising:
a decorative layer composed of a resin impregnated decorative sheet; and
a core layer composed of plural resin impregnated core sheets of core paper, a bottom sheet of the plural resin impregnated core sheets is subjected to a parchment treatment, and the bottom sheet is an exposed sheet at a bottom of the decorative laminate.
2. The decorative laminate according to claim 1 , wherein the plural resin impregnated core sheets are impregnated with phenol formaldehyde resin.
3. The decorative laminate according to claim 1 , further including an overlay paper layer positioned on top of the decorative layer.
4. The decorative laminate according to claim 3 , wherein the overlay paper layer is preferably a melamine impregnated paper layer.
5. The decorative laminate according to claim 1 , wherein the decorative sheet is 60-205 grams/meter 2 , pigment filled, alpha cellulose paper impregnated with a water alcohol or water solution of melamine-formaldehyde resin.
6. The decorative laminate according to claim 1 , wherein the core layer is composed of an upper first resin impregnated core sheet of Kraft paper and the bottom sheet that is a bottom second resin impregnated core sheet of Kraft paper.
7. The decorative laminate according to claim 6 , wherein the first and second resin impregnated core sheets are 160-550 grams/meter 2 resin impregnated Kraft paper.
8. The decorative laminate according to claim 6 , wherein the upper first resin impregnated core sheet is impregnated with a phenol formaldehyde resin composition and is partially cured.
9. The decorative laminate according to claim 8 , wherein the upper first resin impregnated core sheet is impregnated with phenol formaldehyde resin such that the phenol formaldehyde resin is 25% to 35% of a final weight of the upper first resin impregnated core sheet.
10. A laminate lay-up, comprising:
a decorative layer composed of a resin impregnated decorative sheet; and
a core layer composed of plural resin impregnated core sheets of core paper, a bottom sheet of the plural resin impregnated core sheets is subjected to a parchment treatment and is an exposed sheet at a bottom of the laminate lay-up.
11. The laminate lay-up according to claim 10 , wherein core layer is composed of an upper first resin impregnated core sheet composed of Kraft paper and the bottom sheet is a bottom second resin impregnated core sheet composed of Kraft paper.
