USE OF A POLYOLBLANDING SCOPE TO CREATE A PU-BASED ART GRACE

摘要

The invention relates to a method of manufacturing an artificial turf (600, the method comprising: - creating (102) fluid polyurethane mass (210), the creation comprising reacting first and second polyols with an isocyanate, –ªthe first polyol being a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadiendiol; –ªthe 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 (104) an artificial turf fiber (501) into a carrier (308) such that a first portion (302) of the fiber protrudes to the front side of the carrier and that a second portion (506) of the fiber is located at the back side of the carrier; and - adding (106) the fluid polyurethane mass on the back side of the carrier; and - hardening (108) the fluid polyurethane mass.
