Abstract

The invention discloses a water-permeable plastic runway in the related technical field of plastic runways. The water-permeable plastic runway comprises a composite surface layer, a flexible reticularlayer, a base layer and an adhesive layer which are sequentially arranged from top to bottom, wherein the flexible reticular layer comprises a high-elasticity polyurethane elastomer, a plurality of first water seepage holes penetrating through the composite surface layer are formed in the composite surface layer, a second water seepage hole is formed between every two adjacent first water seepageholes, the hole diameter of the first water seepage holes is larger than that of the second water seepage holes, an irregular protruding layer is arranged on a surface of the base layer, the protruding layer and the flexible net-shaped layer form a drainage network layer, and a plurality of drainage holes penetrating through the base layer are formed in the base layer. a plurality of drainage grooves are formed in an upper surface of the adhesion layer and are connected with the drainage holes, the water on a surface of the plastic runway can be drained in time to avoid influence of the accumulated water on use and influence of the accumulated water on the service life of the plastic runway, elasticity is good, and the plastic runway is safe, environment-friendly and harmless to human body.

Description

technical field [0001] The invention relates to the related technical field of plastic runways, in particular to a permeable plastic runway. Background technique [0002] Plastic track, also known as all-weather track and field track, is made of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber granules or PU granules, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. [0003] Since the pouring materials of the plastic runway are mostly polymers, the water permeability is poor. Once it encounters rainy and snowy weather, it is easy to form water accumulation on the surface. Affect the service life of the plastic runway. Thereby developing a kind of permeable plastic runway to sol...
