Embodiment 3
[0036] Making Water-Soluble Resin Modified Polyurethane Breathable Plastic Sports Track
[0037] The weight ratio of the above-mentioned water-soluble resin-modified polyurethane adhesive to the waste tire particles with a particle size of 3 mm is 1:5, and according to the method of embodiment 2, the water-soluble resin polyurethane non-threshing plastic sports track is made into a sports track with a thickness of 9 mm. Then the above-mentioned water-soluble resin-modified polyurethane adhesive and the anti-skid particles with a particle size of 1.5 mm are mixed in a weight ratio of 1:0.5, and the weight ratio of the above-mentioned water-soluble resin-modified polyurethane adhesive is added. After diluting 20% of the butyl acetate material, spray the above material on the primer layer with a spraying machine, with a thickness of 3mm, to form an irregular non-slip pockmarked air-permeable plastic runway, draw lines as required, and then make into a breathable plastic sports ...
