Abstract

The invention discloses a recyclable prefabricated runway. The runway comprises a surface layer and a bottom layer which are compounded after prefabrication and molding, wherein the surface layer comprises a polyurethane elastomer, an SEBS thermoplastic elastomer, polypropylene, maleic anhydride grafted polypropylene, calcium carbonate, emery, white oil, stearic acid, polyethylene wax, an antioxidant, a light stabilizer and a pigment in specific parts by weight; the bottom layer is prepared from a polyurethane elastomer, an SEBS thermoplastic elastomer, polypropylene, maleic anhydride grafted polypropylene, polyethylene vinyl acetate, calcium carbonate white oil, stearic acid, polyethylene wax, an antioxidant, an AC foaming agent and pigment in specific parts by weight. The invention also provides a preparation method and a recycling method of the recoverable prefabricated runway. According to the recyclable prefabricated runway and the preparation method and the recycling method thereof, the performance is excellent, safety and environment friendliness are achieved, and all old runways can be recycled and reprocessed.

Description

technical field [0001] The application relates to the technical field of sports ground materials, in particular to a recyclable prefabricated runway and its preparation method and recycling method. Background technique [0002] Plastic track, also known as all-weather track and field track, is usually composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, and pigments, additives, fillers, etc. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as an excellent all-weather outdoor sports floor material. [0003] At present, polyurethane plastic runways are generally made of EPDM rubber particles, polyurethane slurry and other auxiliary materials on-site pouring and paving. However, the on-site pouring and paving construct...
