Abstract

The invention provides an environment-friendly mixed plastic runway, which includes an upper connection block, a middle connection block, and a lower connection block, and the middle connection block is matched with the upper connection block and the lower connection block respectively; The first mounting plate is provided with a first elastic layer and a second elastic layer in sequence; the first elastic layer is a hybrid elastic layer; and the second elastic layer has the same structure as the first elastic layer. The invention provides a modular environment-friendly mixed plastic runway prepared with shoe material waste as the main raw material. The invention uses shoe material waste instead of EPDM rubber particles as the elastic filler in the mixed runway, which can not only achieve the elastic performance of the plastic runway At the same time, part of the shoe material waste can be turned into usable resources, reducing waste and the adverse impact on the environment during disposal; and the assembly is convenient, which can effectively reduce the impact of thermal expansion on the elasticity of the plastic track.

Description

technical field [0001] The invention belongs to the technical field of sports facilities, and in particular relates to an environment-friendly mixed plastic track and a preparation method thereof. Background technique [0002] According to actual surveys, the entire Huidong County produces about 300 tons of shoe waste every day. Footwear industry scraps account for about 20%-40% of the total amount of materials used. Most shoe-making enterprises in Huidong County have relatively simple and rough management of shoe waste. There is no written waste management regulation, and shoe waste is not classified and stored, which increases the difficulty of subsequent treatment of waste. The local shoe industry waste treatment method is relatively simple, most of which are transported abroad, and there are no large-scale shoe industry waste recycling enterprises in the local area. Most of the recyclable waste still ends up in landfills. For this situation, the government should stre...
