Problems solved by technology

[0003] Using recyclable waste particles as fillers for polyurethane midsoles or insoles, the main problems are the small filling amount of particles, high density, high molding defective rate, and poor mechanical properties.
Usually, if the recyclable particles account for more than 20% by weight of the product and the product density is lower than 300g / L, the molding defect rate and mechanical properties of the product will be severely attenuated, making it difficult to meet the actual use needs
CN112341588A discloses a low-density polyurethane midsole composition containing recyclable waste particles and a preparation method for the midsole, which mainly includes polyether ester polyol 1, polyester polyol 2, recyclable waste particles, and the content of waste particles is high and low Density and excellent mechanical properties, but the cost of raw materials is high, and the cost is too high to be economically feasible, and the content of waste and recyclable old particles is still low, and the mechanical properties still need to be improved

Description

technical field [0001] The invention belongs to the technical field of polyurethane, and specifically relates to a low-density polyurethane midsole composite material containing recyclable waste particles and a preparation method thereof. Background technique [0002] PU, EVA, PVC, PE, PP and other foamed plastic materials have been widely used due to their excellent performance, which has also led to the generation of a large amount of aging waste. Under the carbon neutral environmental protection policy of carbon peak, the above-mentioned The recycling of waste materials has become an urgent problem to be solved in recent years. The waste is crushed into fine flakes or granules as fillers by crushing, which not only recycles the waste, helps the relevant industrial chain to achieve low-carbon, circular, and sustainable development, but also effectively reduces the cost of the product. It is the current waste such as PU An important development direction of product recycli...
