摘要:
研究了普通硫化(CV)体系、半有效硫化(SEV)体系、有效硫化(EV)体系和过氧化二异丙苯(DCP)硫化体系对杜仲胶(EUG)复合材料力学性能及电磁屏蔽效能的影响。结果表明,CV体系、SEV体系和EV体系的硫化速率相差不大,而DCP硫化体系的硫化速率和交联程度最低,并且表现出最高的结晶程度;硫黄硫化体系EUG复合材料的扯断伸长率均高于过氧化物硫化体系,但拉伸强度较低,相较于硫黄硫化体系,使用DCP硫化时EUG复合材料的拉伸强度最高可提升10.6%;硫黄硫化体系EUG复合材料表现出较高的电导率,其交联密度更大,有利于导电网络的形成;EV体系EUG复合材料的电磁屏蔽效能较未硫化时提升了22%。
Abstract:
The effects of common vulcanization (CV) system, semi-effective vulcanization (SEV) system, effective vulcanization (EV) system, and dicumene peroxide (DCP) vulcanization system on the mechanical properties and electromagnetic shielding effectiveness of Eucommia ulmoides gum (EUG) composites were studied. The results showed that the difference in vulcanization rates of CV system, SEV system and EV system was not significant, and the DCP vulcanization system had the lowest vulcanization rate and crosslinking degree, and exhibited the highest crystallinity degree. The elongation at break of EUG composites of the sulfur vulcanization systems were all higher than that of EUG composite of the peroxide vulcanization system, but the tensile strength was lower, and when DCP was used as the vulcanization agent, the tensile strength of EUG composite could increase by up to 10.6% compared with that of EUG composites of the sulfur vulcanization systems. EUG composites of sulfur vulcanization system exhibited good conductivity and the higher crosslinking density, which was conducive to the formation of conductive network, and the electromagnetic shielding effectiveness of EUG compo-sites of the EV system was 22% higher than that of EUG composites of the unvulcanized system.
