摘要

向乙烯-醋酸乙烯共聚物（Ethylene-vinyl acetate copolymer，EVA）无卤阻燃热缩材料中添加不同含量的三烯丙基异氰脲酸酯（Triallyl isocyanurate，TAIC），然后采用电子束辐照，制备出交联型无卤阻燃EVA热缩材料。考察TAIC的含量和吸收剂量对样品的凝胶含量、机械性能和电性能的影响，并通过傅里叶红外（Fourier transform infrared，FTIR）光谱对EVA热缩材料进行表征。结果表明：TAIC的加入对辐射交联有促进作用，在吸收剂量一定的情况下，如150 kGy，EVA热缩材料的凝胶含量随着TAIC含量增加；在TAIC的添加量一定的情况下，如3份（质量），EVA热缩材料的凝胶含量随着吸收剂量增加；对机械性能而言，断裂伸长率随着TAIC和吸收剂量的增加均呈下降趋势；在断裂强度方面，添加TAIC的样品断裂强度上升趋势比较明显；对电性能的影响，TAIC的加入增加了EVA热缩材料的体积电阻，其随着吸收剂量的增加先上升后下低；FTIR分析表明TAIC在电子束辐照下反应完全。

Abstract

Ethylene-vinyl acetate copolymer (EVA) was blended with different contents of triallyl isocyanurate (TAIC) to prepare halogen-free flame retardant heat shrinkable material by the electron beam irradiation crosslinking. Effects of TAIC content and absorbed dose on gel content, mechanical properties, and electrical properties of samples were studied. And the EVA heat shrinkable materials were characterized by the Fourier transform infrared (FTIR) spectroscopy. The results showed that the gel content of EVA heat shrinkable material increased with the TAIC content in the case of absorbed dose remaining unchanged, e.g. 150 kGy, and the gel content increased with the absorbed dose while adding certain TAIC, e.g. 3 phr (parts per hundred as for mass), which indicated that TAIC could promote the role of irradiation crosslinking. The elongation at break decreased with the icreasing TAIC contents and the increasing absorbed doses. However, the tensile strength of the samples increased with the TAIC content. Test results of volume resistance showed that with TAIC contents increasing, volume resistance of EVA heat shrinkable materials increased at first, and then decreased with the increasing absorbed doses. The FTIR analysis showed that the TAIC reaction was complete under the electron beam irradiation.
