SEBS对EVA发泡材料性能影响的研究

Study of Effect of SEBS on Property of Foamed EVA

将苯乙烯-乙烯/丁烯-苯乙烯共聚物(SEBS)应用于乙烯-醋酸乙烯共聚物(EVA)发泡材料中。讨论了EVA/SEBS发泡材料中,SEBS用量对产品力学性能的影响,并通过高级动态流变仪对流变学性能的研究,结合SEM对发泡样品的切断面观察,讨论了SEBS对EVA发泡材料力学性能产生影响的原因。通过交联度的测定,分析了SEBS的加入对EVA/SEBS流变学性能产生影响的原因。

SEBS was blended with EVA to prepare a foamed plastic product. The effect of SEBS content on the mechanical properties of the foamed plastics was studied, and the rheological behaviour of the foamed plastics was also studied by means of advanced Rheometer. Based on the study of the section of the sample by SEM, the reason for the effect of SEBS on the mechanical properties of foamed EVA was discussed. The reason for the effect of SEBS on the rheological behaviour of the foamed EVA was also analyzed by means of the determination of the degree of crosslinking.
