Description

EPU energy runway

Technical Field

The utility model relates to the technical field of sports goods, in particular to an EPU energy runway.

Background

The plastic track is an indispensable important facility in a modern track and field site, compared with the traditional soil track, the plastic track has the advantages of good elasticity, skid resistance and wear resistance, easy field nursing, bright color, attractive appearance, orderliness and the like. In addition, NCO in the polyurethane preparation process is consumed by adding water for reaction, so that the strength of a finished product of the polyurethane track is seriously reduced, and the physical properties such as durability, tearing strength and the like of the track are influenced. In addition, in the production and synthesis process of a single-component polyurethane factory, a chain extension cross-linking agent (such as a common cross-linking agent MOCA) cannot be added, so that the strength of a single-component polyurethane track finished product is always lower than that of a double-component polyurethane track product on the same cost level, the cost performance is not high, the technical purpose of the EPU energy track is to avoid the unstable construction phenomenon of the existing foaming track, and meanwhile, the EPU energy track can meet the current mandatory requirement of the finished product on physical performance indexes. Therefore, we improve this and propose an EPU energy runway.
