摘要： An ultra-light graphene-rubber foam particle for soles is prepared from, by weight, 60-65 parts of natural rubber, 8-12 parts of isoprene rubber, 8-12 parts of butadiene rubber, 6-8 parts of styrene butadiene rubber, 0.8-1.0 parts of modified graphene, 0.08-0.12 parts of poly(N-vinylacetamide), 0.8-1.0 parts of silicone oil, 3.0-3.5 parts of inorganic nano-particles, 1.2-1.5 parts of activated zinc oxide, 0.8-1.0 parts of zinc stearate, 1.0-1.2 parts of stearic acid, 0.8-1.0 parts of cross-linking agents, 2.0-3.0 parts of flow promotors, and 1.5-1.8 parts of foaming agents. According to the invention, the modified graphene is uniformly dispersed into the rubber materials, so that the ultra-light graphene-rubber foam particle has good thermal stability, wear resistance and tensile strength, the permanent compressive-deformation performance and thermal contraction resistance are improved, and the weight is reduced by over 50%.
