Nano PU (Polyurethane) plastic runway with good low-temperature mobility and manufacturing method thereof

The invention relates to a nano PU (Polyurethane) plastic runway with good low-temperature mobility and a manufacturing method thereof. Glue liquor of the plastic runway is divided into a component group A and a component group B in a weight ratio of (1-10):)(3-8), wherein the component group A comprises polyether glycol and MDI (Diphenylmethane Diisocyanate) in a weight ratio of (50-70):(20-40); the component group B comprises polyether glycol, MOCA, an Z-100 plasticizer, iron oxide red, white carbon black, nano calcium carbonate and nano clay in a weight ratio of (10-40):(1-10):(20-40):(1-10):(1-20):(30-50):(1-10). According to the invention, under a low temperature in winter, after Z-100 plasticizer is used to replace a chlorinated paraffin plasticizer, viscosity of the component group B is lowered by 10-15 times, mobility of the nano PU plastic runway is increased, and application property of the PUC plastic runway is improved.
