Technical Field
The invention relates to the technical field of plastic runways, in particular to a breathable plastic runway and a manufacturing method thereof.
Background
The plastic track is also called as an all-weather track and field sports track, has the characteristics of good flatness, high compressive strength, proper hardness and elasticity and stable physical performance, is beneficial to the exertion of the speed and the technology of athletes, effectively improves the sports achievement and reduces the injury rate. The plastic track has certain elasticity and color, certain ultraviolet resistance and aging resistance, and is the best all-weather outdoor sports ground floor material internationally recognized. The plastic track is used for various schools, professional stadiums, track and field tracks, semicircular areas, auxiliary areas, all-people fitness paths, indoor gym training tracks, playground road pavement, indoor and outdoor tracks, tennis, basketball, volleyball, badminton, handball and other places, and activity places such as parks, residential quarters and the like. The plastic track is non-toxic and harmless to the environment and human body. And the plastic track has the characteristics of ultraviolet light resistance, abrasion resistance, burst resistance, ageing resistance, long service life, easiness in maintenance, low maintenance cost and the like. At present, although the existing compact type of the plastic track is airtight, the problem of air permeability cannot be thoroughly solved even though a layer of plastic can be sprayed on the surface particles of the plastic track to relieve the problem. Moreover, at high temperature, steam and water vapor generated by the foundation cannot be diffused rapidly, and the plastic track generates a bubbling phenomenon.
