Abstract

The invention discloses an ultra-light graphene rubber foamed insole and a preparation method thereof. The ultra-light graphene rubber foamed insole is prepared from the following raw materials in parts by weight: 65-72 parts of ethylene-vinyl acetate copolymer, 18-22 parts of liquid polyisoprene rubber, 5-7 parts of methyl vinyl phenyl silicone rubber, 6-9 parts of graphene, 12-19 parts of EVA color masterbatches, 4-7.2 parts of an aluminum silicate fiber pipe, 1.5-2.5 parts of a foaming agent, 0.9-1.2 parts of a micropore regulator, 3-6 parts of an antioxidant, 2-4.2 parts of a crosslinkingagent and 4-6 parts of zinc stearate. The ultra-light graphene rubber foamed insole is low in density, has ultra-light property, is high in resilience rate and durable, does not easily deform in a using process, is moderate, is comfortable, and has high quality, and the circumstance that the insole is damaged due to over large deformation; and the ultra-light graphene rubber foamed insole is highin water absorption rate and air permeability, good in moisture absorption, good in air permeability and comfortable to wear.

Description

technical field [0001] The invention relates to the field of EVA rubber products, in particular to an ultra-light graphene rubber foam insole and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional carbon nanomaterial in which carbon atoms form a hexagonal honeycomb lattice with sp2 hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. The common powder production methods of graphene are mechanical exfoliation method, redox method, and SiC epitaxial growth method, and the film production method is chemical vapor deposition (CVD). [0003] As a polymer material, ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the EVA material after foaming treatment has the advantages of l...
