Abstract
This invention relates to a process for the production of elastic composites, preferably used as floor coverings, from plastics granulates and polyisocyanates acting as binders. The process broadly comprises coating the plastic granulates with a paste of hydroxyl containing polyether, filler, and optionally pigment, subsequently mixing the coated granulates with the polyisocyanate binder, and thereafter molding and curing the resultant composite.
Claims5
A process for the production of an elastic composite comprising:
- a. coating rubber and/or elastomeric plastic granulates with a paste of
- i. a hydroxyl containing polyether and
- ii. mineral fillers and/or pigments,
- b. subsequently mixing a polyisocyanate binder therewith, and
- c. hardening the resultant mixture.
