The invention discloses
polyurethane viscose for preparing a high-performance
artificial turf and a preparation method thereof, a method for preparing the
artificial turf by using the
viscose and the
artificial turf obtained by the method. The
polyurethane viscose is prepared from the following raw materials in part by
mass: 100 parts of polyalcohol, 5 to 15 parts of chain
extender, 0 to 5 parts of color paste, 100 to 200 parts of
inorganic filler, 0.5 to 1.5 parts of catalyst, 30 to 100 parts of water inhibitor and 30 to 100 parts of
isocyanate. The method for preparing the artificial turf by using the viscose comprises the following steps of: uniformly spraying the raw materials onto a main bottom lining of the artificial turf through a mechanical pump, scraping the materials through a scraper, pre-heating the materials by
infrared, heating the materials in a
drying channel, and finally curing, perforating and packing the materials. 600 to 1,000 grams of viscose is applied to each
square meter of artificial turf, the tested pullout force of the grass can be more than 80N after the artificial turf is placed for 24 hours at the
room temperature, and the main bottom lining is soft and has good
toughness.
