Breathable plastic track

Abstract

The invention discloses a breathable plastic track which comprises a water absorbing layer, an isolation layer, a base layer and a surface layer from bottom to top. The base layer is a composite structure formed by a polyurethane binder and elastic rubber particles. The surface layer is a concave-convex structure formed by soft rubber and the polyurethane binder and is provided with track lines. The track lines are provided with fluorescent layers. The isolation layer is used for isolating the base layer from the water absorbing layer and is provided with a plurality of uneven exhaust passages. When in contact with the breathable plastic track, the water flows into the water absorbing layer through the water-passing holes of the insulation layer so as to be prevented from staying in the base layer for a long time. Thus, the water is prevented from being unable to evaporate in the rainy weather and thus causes the track to bulge. In the high-temperature weather, the water in the water absorbing layer is evenly distributed, evaporates together, and has a fast evaporation speed. In addition, the track lines are made of fluorescent materials, are convenient to see in the dark or at night, and are attractive in appearance.

Description

technical field [0001] The invention relates to a breathable plastic runway. Background technique [0002] As we all know, plastic track is an indispensable and important facility in modern track and field. Compared with traditional soil track, it has good elasticity, anti-skid, wear resistance, shock absorption, easy site maintenance, bright colors, beautiful and tidy, etc. . In view of the above advantages, the plastic runway was quickly adopted by various track and field venues soon after it came out. Sports are one of the favorite activities of people in their spare time. Therefore, scientific and humanized sports facilities are directly related to the health of athletes. When encountering rainy days, there will be water in the base of the plastic runway. After the rain stops, the water in the base will evaporate through evaporation, so that the neat pressure cannot be gathered, thereby avoiding the phenomenon of bubbling. However, due to the water-based environmental ...

Problems solved by technology

When encountering rainy days, there will be water in the base of the plastic runway. After the rain stops, the water in the base will evaporate through evaporation, so that the neat pressure cannot be gathered, thereby avoiding the phenomenon of bubbling. However, due to the water-based environmental protection and breathability In the process of paving the plastic runway, due to the unevenness of the ground, there will inevitably be concave parts in the base layer. In rainy days, due to the existence of the concave parts, the rainwater here will evaporate slowly. Make the water in the base layer unable to evaporate, and make the runway bulge
