Abstract
A process for the manufacture of a laminate, in particular a continuously pressed laminate, CPL, which can be used, for example, as a surface laminate in the manufacture of worktops or floor panels. The process includes the provision of a finish foil and a support structure, as well as the pressing of the finish foil with the support structure in a CPL process. The provision of a support structure includes impregnating the support structure with phenolic resin. The finish foil is provided with a decorative pattern and a three-dimensional structure that is synchronized with the decorative pattern.
Claims18
A method for producing a laminate, comprising the following steps:
- providing a finish foil, wherein the finish foil is provided with a decorative pattern and a three-dimensional structure, where the three-dimensional structure is synchronized with the decorative pattern;
- providing a support structure, wherein the support structure is provided with a phenolic resin;
- and
- pressing of the finish foil with the support structure in a CPL-continuously pressed laminate (CPL) process,
- wherein the phenolic resin is a phenol-formaldehyde resin;
- wherein the phenolic resin includes a curing agent such that the phenolic resin has a turbidity time at 100 degrees Celsius of 3.0 to 7.0 minutes;
- wherein the resin content in the support structure is 70 to 99% by weight;
- wherein providing the support structure includes impregnating the support structure with the phenolic resin;
- wherein volatile matter after drying of the impregnate are in a range between 6.5% and 9.0%.
A laminate, comprising:
- a finish foil;
- and
- a support structure, wherein the support structure is provided with a phenolic resin;
- wherein the finish foil is provided with a decorative pattern and a three-dimensional structure, where the three-dimensional structure is synchronized with the decorative pattern,
- wherein the finish foil is pressed with the support structure to form the laminate, and
- the laminate having a thickness of from 0.1 to 2.0 mm.
