Embodiment
[0009] Embodiment: According to the existing plastic runway construction method, the polyurethane slurry is spread on the runway foundation that has been done. After the polyurethane slurry is solidified to form the bottom layer, the polyurethane slurry and polyurethane granules are pressed in a weight ratio of 1: 2.0. The prepared mixture can be sprayed on the cured polyurethane bottom layer under high pressure.

The plastic track constructing method features that after polyurethane slurry is spread on track base and cured to form the base layer, ethylene propylene terpolymer grains or the mixture of polyurethane slurry and polyurethane grains in the weight ratio of 1 to 1.5-2.5 is high pressure sprayed with a plastic spraying machine onto the cured polyurethane base layer to form the face layer. The said construction method can prevent grain separating problem in plastic track, and has high construction efficiency, low cost and long track service life.
Description
Technical field [0001] The invention relates to a plastic runway, more specifically a construction method for a plastic runway that is not easy to thresh. Background technique [0002] With the development of science and technology, plastic track is replacing the traditional cinder track with its advantages of flatness, beauty, non-slip, wear resistance, good elasticity, breathability, not easy to deform, safe use, and will not hurt athletes, and is widely used. Nowadays, both international and domestic track and field competitions use plastic tracks. According to international standards, the thickness of the plastic runway is 13 mm, the bottom layer is a colored polyurethane slurry solidified layer, the thickness is 10 mm, and the surface layer is a polyurethane rubber particle layer bonded to the bottom layer, the thickness is 3 mm. [0003] In the prior art, the construction method of the plastic runway is: spread polyurethane slurry on the base of the runway according t...
