Abstract

The invention discloses a prefabricated coil polyurethane runway surface layer and a construction process thereof and specifically relates to the field of sports materials. The prefabricated coil polyurethane runway surface layer comprises a laid base layer, wherein the top of the laid base layer is provided with a prefabricated laid coil; a polyurethane bonding layer is arranged between the prefabricated laid coil and the laid base layer; a polyurethane reinforcing layer is arranged on the top of the prefabricated laid coil; a spraying surface layer is arranged on the top of the polyurethanereinforcing layer; and the prefabricated laid coil comprises an elastic supporting layer and foaming polyurethane layers. According to the prefabricated coil polyurethane runway surface layer and theconstruction process thereof, disclosed by the invention, by preparing a polyurethane two-component composite material, and preparing water-based polyurethane foaming fluid in a factory to cast the integrated prefabricated laid coil with the elastic supporting layer, the quality of the coil is improved; laying is convenient; the elastic supporting layer is cooperated with the foaming polyurethanelayers to improve the elastic properties; the coil is resistant to deformation; the rebound effect is good; a woven mesh is arranged in the polyurethane reinforcing layer; the runway toughness is improved; the tensile strength is improved; and the impact absorptivity and overall performance of a surface layer structure are improved.

Description

technical field [0001] The invention relates to the field of sports materials, more specifically, the invention relates to a prefabricated coil polyurethane track surface and its construction technology. Background technique [0002] The surface layer of the synthetic material sports field must meet the requirements of the relevant physical and mechanical properties and durability performance stipulated by the International Federation of Athletic Associations and national standards. The impact absorption performance of the surface material made by the cast-in-place process from the all-plastic type and the mixed type has been difficult to meet the standard (except for the breathable type and the composite type). The prefabrication process adopts a special structural form, that is, irregular regular holes are made at the bottom of the rubber coil. This structure can release the surface layer well when it is subjected to external impact force, and buffer the external impact f...
