The packing material composition for the land magnetic track recycling the waste polyurethane foam and land magnetic track construction method
According to the present invention, an elastic packing material composition for a land track using recycled waste polyurethane (PU) comprises: a PU resin composition for a soft layer, which is obtained by uniformly mixing, based on 100 parts by weight of a urethane prepolymer having two or more isocyanate end groups, to 30 to 40 parts by weight of waste PU chips generated when replacing athletics tracks, 20 to 30 parts by weight of a curing agent containing a polyol compound having two or more hydroxyl groups per molecule, 2 to 5 parts by weight of a foaming agent, 0.01 to 0.1 parts by weight of a catalyst, 1 to 3 parts by weight of a foam stabilizer, and 5 to 10 parts by weight of an additive, and has pores that form a network having a reticular structure; and a semi-hard PU resin composition including, based on 100 parts by weight of a urethane prepolymer having two or more isocyanate end groups, 30 to 40 parts by weight of a curing agent including 10 to 20 parts by weight of waste polyurethane chips generated when replacing the athletics tracks and including a polyol compound having two or more hydroxyl groups per molecule, 5 to 10 parts by weight of a solar insulator, 0.5 to 3 parts by weight of an inorganic pigment, 0.5 to 1 part by weight of an UV stabilizer, and 0.01 to 0.1 parts by weight of a catalyst. Therefore, an environmentally friendly athletics track is constructed using the elastic packing material.
