Problems solved by technology

[0002] In the prior art, the polyurethane track is more common on the sports field, which is generally composed of two layers, namely the bottom layer and the surface layer. The surface layer is generally uniformly laid with a layer of polyurethane particles or rubber particles on the uncured polyurethane layer to achieve the roughness of the track. However, such adhered particles are often easy to fall off. In addition, due to the choice of material formula, the friction performance, elasticity, hardness and shock absorption of the final formed material are improved. the bottleneck
