Composite runway:
Plastic track, also known as all-weather athletics track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. Plastic tracks have the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to athletes' speed and technical performance, effectively improving sports performance, and reducing the rate of falls. Plastic track is composed of materials such as polyurethane rubber, which has certain elasticity and color, and has certain UV resistance and aging resistance. It is internationally recognized as the best all-weather outdoor sports ground flooring material.
Construction process of composite plastic runway:
1. Base surface treatment: Check the flatness of the foundation. The flatness should be within 3mm when measured with a 3m ruler, and the entire site should be flat.
2. Construction of composite runway primer: Use PU adhesive mixed with 30% black rubber powder or talcum powder for black rubber particle bottom sealing,
Back cover maintenance for 24 hours
3. Black rubber particle paving: Use high elasticity black rubber particles with a particle size of 2-4mm mixed with high-strength single component glue, stir evenly and pour
Enter the paver, lay with a thickness of 9mm, and cure and maintain for 24 hours.
4 EPDM elastic layer paving: Mix PU track elastic coating with EPDM evenly, pave, level, and fill holes for leveling.
Spray coating of 5 composite plastic track surface adhesive: Mix the filling material such as red rubber powder evenly and spray it on the surface of the laid black rubber EPDM particles;
6. Line drawing: Use elastic polyurethane special line drawing paint to draw various marking lines according to international standards
