Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to a degradable EVA foaming material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is a rubber-like thermoplastic. Compared with polyethylene, it has excellent flexibility, low temperature brain flexibility, elasticity, stress crack resistance, good plasticity and processability, so it is widely used. Applications. EVA cross-linked foaming material is a non-toxic foaming material with excellent physical properties. Due to the existence of gas phase, it has the advantages of low density, high specific strength, and ability to absorb loads. However, the EVA foam material has the disadvantages of large deformation, insufficient wear resistance, slipping, and hardening at low temperature, which limit its application. [0003] In recent years, there have been many researches on EVA cross-linked foaming materials at home...
