Abstract
The present invention relates to 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.
Claims24
A method for producing a laminate, in particular a continuously pressed laminate, CPL, comprising the following steps:
- providing a finish foil;
- 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 process,
- wherein the phenolic resin is a phenol-formaldehyde resin;
- wherein said phenolic resin comprises 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 comprises impregnating the support structure with phenolic resin;
- wherein volatile matter after drying of the impregnate are in the range between 6.5% and 9.0%.
