Problems solved by technology

[0006] 1. It is impossible to recycle ethylene-vinyl acetate copolymer scraps reasonably and with high value, because the repeated use of ethylene-vinyl acetate copolymer scraps will cause tensile strength and tear strength, bending resistance, rebound rate and size The comprehensive performance such as shrinkage becomes worse, and the service life of the sole material is short, and the comfort is poor;
[0007] 2. The cost of recycling ethylene-vinyl acetate copolymer scraps is high
