摘要

为改善芳纶纤维(PPTA)与丁腈橡胶(NBR)复合材料之间的界面强度, 采用硅烷偶联剂A172和氧化石墨烯(GO)对芳纶纤维表面进行接枝改性处理, 并对处理前后的芳纶纤维进行化学结构、表面形貌及H抽出力分析。利用SEM对抽出纤维表面和橡胶基芳纶纤维复合材料截面进行微观结构分析。结果表明: 硅烷偶联剂和氧化石墨烯对芳纶纤维进行二次表面改性后, 纤维表面含氧基团增加, 化学活性提高, 处理后表面存在明显的表层附着物, 纤维结构未发生明显损伤且表面粗糙度得到明显改善。每个处理阶段后H抽出力均有提高, 且氧化石墨烯二次改性后的芳纶纤维H抽出力提高效果最佳, 从18.192 MPa提高到48.748 MPa, 芳纶纤维与丁腈橡胶的界面结合力得到了显著提升, 从而证实了硅烷偶联剂和氧化石墨烯二次改性芳纶纤维的有效性, 为橡胶基芳纶纤维复合材料性能的研究提供了参考。

Abstract：

To improve the interface strength between aramid fiber (PPTA) and NBR composites, the silane coupling agent (A172) and graphene oxide (GO) were used to have the graft modification treatment to the aramid fiber surface and analyze the chemical construction, surface topography and H-pull test of aramid fiber before and after treatment. The microstructure of the pull out fiber surface and section of the rubber-based aramid fiber reinforced polymer(AFRP) was analyzed by SEM. The results show that the oxygen-containing groups on the fiber surface are increased and the chemical activity is improved after the secondary surface modification to the aramid fiber is conducted with the silane coupling agent and GO. The obvious attachments can be found on the surface after treatment. The fiber structure has no obvious damage and its surface roughness is improved substantially. The H-pull test after treatment increases with an optimal effect of aramid fiber H-pull test after the secondary modification with GO (improved to 48.748 MPa from 18.192 MPa). The interface bonding strength between the aramid fiber and NBR is improved dramatically, thus confirming the effectiveness of the silane coupling agent and GO in the secondary modification to the aramid fiber, which provides reference for the study of the performance of the rubber-based AFRP.

Key words： aramid fiber graphene oxide silane coupling agent surface modification interface strength
