The present invention relates to ground materials for a four season sledding place, and a manufacturing method thereof, and more specifically, to ground materials for a sledding place, which are characterized in that polycarbonate, polymethylmethacrylate, ethylene-propylene-diene monomer rubber are mixed and used in addition to copolymer of polyethylene and ethylene vinyl acetate as resin components, and polydimethylsiloxane and erucamide are added and used as a slip agent, and a manufacturing method thereof. When ground materials for a sledding place is manufactured according to the present invention, the heat-resistance is strengthened, the resistance against the friction heat is strengthened, and the mixability and the kneadability between resin components are improved. As the durability is improved, the durability of the ground material is remained excellent after a long term use. As the slip property is maintained at a high level after a long term use, the ground material does not need to be replaced frequently. |
