本文研究了尼龙6—NR/SBR复合材料的流变性能和应力松驰特性,并利用扫描电镜(SEM)分析了复合材料的各种断面的形貌结构,结果发现,复合材料的粘度随短纤维含量的增加而提高,但不改变流变特性,其应力松驰是由两个不同性质的阶段所构成,两个阶段的转折点位置取决于纤维含量,与基质相比复合材料的应力松驰速度大大提高。形貌分析表明,用RFL处理的纤维不但在基质中具有良好的分散性和取向性,而且与基质间的粘合力也显著提高。
In this paper, the rheological properties and stress relaxation properties of nylon 6-NR / SBR composites were investigated. The morphology of various cross-sections of the composites was analyzed by scanning electron microscopy (SEM). The results showed that the viscosity of the composites varied with the short Fiber content increases but does not change the rheological properties of the stress relaxation is composed of two different stages of nature, the turning point of the two stages depends on the fiber content, compared with the matrix stress relaxation of the composite Speed greatly increased. Morphology analysis shows that the fibers treated with RFL not only have good dispersibility and orientation in the matrix, but also significantly improve the adhesion to the matrix.
