Soft plastic running track, preparation method thereof and application thereof

Abstract

The invention discloses a soft plastic running track and a preparation method thereof. The running track is sequentially provided with a basic layer, an elastic layer, a foaming buffer layer, a reinforcing layer and a decorative surface layer from bottom to top. Compared with a conventional plastic running track, the soft plastic running track disclosed by the invention has greater impact absorption and vertical deformation performance so as to achieve the property of being softer and generate more comprehensive resistance. The resistance can bring extra loads for support segments of athletes,so that hip extensors of support legs of the athletes can obtain effective strength training and support legs and knees in a larger working range, and at the same time, the strength of ankle joints can be effectively developed. Therefore, the plastic running track is particularly suitable for the training of single-foot jumping and stride jumping. Meanwhile, the plastic running track also has excellent tensile strength and elongation at break, thereby achieving relatively excellent service life performance.

Description

technical field [0001] The invention relates to the field of plastic running tracks, in particular to a soft plastic running track and its preparation method and application. Background technique [0002] Polyurethane plastic track, also known as all-weather sports track, is composed of polyurethane prepolymer, mixed polyether, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic running track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is beneficial to athletes' speed and technical performance, effectively improving sports performance, and reducing the rate of falls. It is widely used. However, most of the physical characteristics of the plastic track commonly used in the market at present refer to the standards of GB / T 22517.6-2011 "Sports Field Use Requirements and Inspection Methods Part 6: Track and Field Field" and the IAAF Track and Field Fa...

AI Technical Summary

Problems solved by technology

[0003] With the deepening of sports-specific research, more and more researchers have found that specific special training, such as kicking in sprints, running on the way, striding jumps and other special techniques, is more effective than regular sports training in specific sports venues. It is more effective and can be closer to the special requirements to the greatest extent. The energy supply characteristics also conform to the law of special energy metabolism. However, there is currently no plastic track that meets the above special training requirements.
