摘　　要：基于氢安全检测需求,本文研制出了一种可透氢气的弹性体材料,本研究以透氢胶体为研究对象,其主要组分为复合硅材料基体和透氢助剂成分,调节乙烯-醋酸乙烯无规共聚物和聚乙烯醇的复配基体及增韧系统;取复合基体(乙烯-醋酸乙烯无规共聚物+聚乙烯醇)为50/50(%)中分别加入弹性体增韧剂马来酸酐接枝三元乙丙橡胶(EPDM-g-MAH)、马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)、马来酸酐接枝加氢苯乙烯-丁二烯-苯乙烯共聚物(SEBS-g-MAH)、韧性好模量低的增韧树脂茂金属聚乙烯(mPE)及刚性粒子碳酸钙,探索不同增韧剂体系对透氢体系力学性能的影响。研究结果表明,复合硅胶基体为50/50(%)时性能最优,弹性体增韧明显改善了透氢材料力学性能,其次为mPE,而适当使用刚性粒子也可起到对体系既增强又增韧的作用,本研究成果可为用氢安全提供保障。Based on the needs of hydrogen safety monitoring and testing,a hydrogen-permeable rubber material was developed in this paper,the hydrogen permeable colloid was taken as the research object,its main components were composite silicon material matrix and hydrogen permeable additives,and the compound matrix and toughening system of ethylene-vinyl acetate random copolymer and polyvinyl alcohol were adjusted.50/50(%)of the composite matrix(ethylene-vinyl acetate random copolymer+polyvinyl alcohol)were added to the elastomer toughening agent maleic anhydride grafted ethylene propylene diene diene diene rubber(EPDM-g-MAH),maleic anhydride grafted ethylene-octene copolymer(POE-g-MAH),maleic anhydride grafted hydrostyrene-butadiene-styrene copolymer(SEBS-g-MAH),toughening resin metallocene polyethylene(mPE)with good toughness and low modulus and rigid particle calcium carbonate.To explore the effects of different toughener systems on the mechanical properties of hy⁃drogen permeable systems.The results showed that the performance of the composite silica gel matrix was the best when it was 50/50(%),and the elastomer toughener had a significant effect on the mechanical properties of the hy⁃drogen permeable system,followed by mPE,and the appropriate use of rigid particles can also play a role in strengthening and toughening the system.
