Abstract

Abstract

In order to improve the dimensional stability of the rubber-based foam material and realize its wide industrialization, an organic scaffold structure was constructed with crystalline ethylene vinyl acetate copolymer (EVA) to enhance the dimensional stability of styrene butadiene rubber (SBR)/EVA composite foam based on the cross-linked structure of sulfur and dicumyl peroxide through mechanical blending. The effects of different content of vinyl ester (VA) content on the crystallinity, compatibility, cell morphology, dimensional stability and mechanical properties of SBR/EVA composites were studied, and the anti-shrinkage mechanism of the EVA crystal area as an organic scaffold structure was explored. The results show that SBR/EVA composites with different VA content of EVA have good foaming behavior. The shrinkage of SBR/EVA composite foam with high crystallinity EVA (18% VA content) is reduced to 4.7% and its hardness and compression stress (60%) are increased to 70 Shore C and 22 MPa, respectively.
