USING A POLYOL MIXTURE COMPRISING PBD FOR CREATING A PU-BASED ARTIFICIAL TURF
Abstract:
Method of manufacturing an artificial turf includes: creating fluid polyurethane mass, the creation comprising reacting first and second polyols with an isocyanate, the first polyol being a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadiendiol; the isocyanate comprising isocyanate monomers, isocyanate polymers or isocyanate prepolymers or a mixture thereof, the isocyanate monomers, isocyanate polymers and the isocyanate prepolymers having two or more isocyanate groups per molecule; incorporating an artificial turf fiber into a carrier such that a first portion of the fiber protrudes to the front side of the carrier and that a second portion of the fiber is located at the back side of the carrier; and adding the fluid polyurethane mass on the back side of the carrier; and hardening the fluid polyurethane mass.
