Claims33
A method for manufacturing a slab comprising solid fillers and organic binders, said method comprises the following steps:
- i) providing a mixture comprising organic binder and solid fillers, wherein said solid fillers comprise first particles and second particles, wherein the second particles are coarser than the first particles;
- ii) providing a substrate layer having an organic binder absorption capacity;
- iii) contacting the mixture of step i) with the substrate layer of step ii);
- iv) exerting a force on the composite obtained in step iii) for migrating at least a part of said organic binder into said substrate layer;
- v) cooling the construction obtained in step iv);
- and
- vi) removing said substrate layer from the construction obtained in step v) for obtaining the slab;
- wherein the mixture of step i) is heated before step iv) is performed.
