Abstract

The invention provides an environment-friendly mixed plastic runway. The environment-friendly mixed plastic runway comprises an upper connecting block, an intermediate connecting block and a lower connecting block, and the intermediate connecting block is correspondingly connected with the upper connecting block and the lower connecting block in a matched mode; the upper connecting block comprisesa first installation plate, wherein the first installation plate is successively provided with a first elastic layer and a second elastic layer; and the first elastic layer is a mixed elastic layer,and the structure of the second elastic layer is consistent with the structure of the first elastic layer. The environment-friendly mixed plastic runway is a modular environment-friendly mixed plasticrunway which uses shoe material waste as a main raw material; the environment-friendly mixed plastic runway adopts the shoe material waste instead of EPDM rubber particles as an elastic filler in themixed runway, so that the elastic performance requirements of the plastic runway can be met, part of the shoe material waste can be enabled to become available resources meanwhile, the waste is reduced, and disposal of the waste of the negative influence on the environment is reduced; and assembly is convenient, and the influence of thermal expansion on elasticity of the plastic runway can be effectively reduced.

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 st...
