The invention discloses a sports ground-used nanometer environmental-friendly type
polyurethane paving material and a preparation thereof, and the paving material consists of A component, B component,
black rubber particles and a catalyst; the A component is: diisocyanate: 20 to 50 percent; polyether
polyol: 40 to 70 percent and a nanometer additive: 5 to 25 percent; the B component is: polyether
polyol : 20 to 40 percent ;
processing aid: 5 to 25 percent; nanometer additive: 0.1 to 5 percent; fillings: 40 to 70 percent, pigments: 0.1 to 2.0 percent;
ultraviolet absorbent: 0.01 to 0.1 percent and antiaging agent: 0.01 to 0.1 percent, wherein, the weight proportion of the A component and the B component is 1:3 to 5, the
black rubber particles account for 20 percent in the sum weight of the A composition and the B component, the catalyst accounts for 0.15 percent in the sum weight of the A composition and the B component. The preparation method is that, the A component and the B component are mixed according to the weight proportion of 1:3 to 5 of the A component and the B component, then the
black rubber particles, the amount of which accounts for 25 percent in the sum weight of the A composition and the B composition are added, and after uniform mixing,
zinc iso-octoate, the amount of which accounts for 0.15 percent in the sum weight of the A composition and the B composition are added, and then the track and field
runway paving-used
polyurethane elastomers are prepared after stirring and
polymerization and solidification. The sports ground-used nanometer environment-friendly type
polyurethane paving material takes low poisonous and
high activity MDI as
raw material and leads the environment-friendly property of the paving materials of plastic sports runways and sports playing courts to reach the
international standard, and improve various physical index of products obviously.
