With ethylene-vinyl acetate-glycidyl methacrylate(EVM-GMA)rubber as matrix,γ-aminopropyltriethoxysilane(APTES)as grafting monomer and azodicarbonamide as foaming agent,double crosslinked foaming materials were prepared by combination of water crosslinking and peroxide crosslinking.The cell morphology,dynamic mecha-nical properties,and physical and mechanical proper-ties of the foaming materials were investigated by scanning electron microscopy,dynamic mechanical property spectrometer and electronic universal tes-ting machine.The results showed that the double crosslinked foaming process could be realized,and the crosslinking network formed by water crosslin-king could effectively improve the uniformity and dispersion of cell size.When the amount of dicumyl peroxide was 0.25 phr(mass),the double crosslinked foam material had the narrowest cell size distribu-tion,the best foaming effect,and better energy ab-sorption effect,which was suitable for application of damping materials.
