Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic running track technology, specifically to a wear-resistant plastic running track material. Background Technology
[0002] Plastic running tracks, also known as all-weather athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Plastic running tracks possess characteristics such as good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are beneficial for athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. However, plastic running tracks are easily damaged by external forces due to frequent trampling by athletes. Furthermore, the hard contact between the track and shoe soles can affect the comfort of athletes during workouts. In addition, athletes wear spiked shoes, and the spikes have a serious destructive effect on the track surface. Repeated punctures can easily lead to localized damage to the track and affect athletes' athletic performance. To ensure the normal use of the track, a new type of plastic running track material is needed. However, existing plastic running track materials still have the following shortcomings:
[0003] When using existing plastic running track materials, most of these materials have low heat resistance and low strength, which makes the surface of the plastic running track prone to wear after long-term use. This affects the service life of the plastic running track, resulting in a decrease in the practicality and efficiency of the plastic running track material.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a wear-resistant plastic running track material. Utility Model Content
