摘要:
采用3种方法对传统炭黑进行表面改性,考察了改性前后炭黑表面形貌及结构的变化,并采用改性炭黑填充天然橡胶(NR)/顺丁橡胶(BR)并用胶,考察了改性炭黑对并用胶力学性能、硫化特性及动态力学性能等的影响。结果表明,与未改性炭黑相比,细化粒径、调高pH值及木质素改性处理后,炭黑表面的粗糙程度增加;且细化改性炭黑具有更高的比表面积,调高pH值改性炭黑具有更多疏松的二次结构,木质素改性炭黑粒径略有增加。对于炭黑填充NR/BR,用细化粒径及调高pH值方法处理的炭黑进行填充,NR/BR硫化胶的力学性能、耐磨性能及抗湿滑性均得到明显改善,但硫化延迟效应明显;木质素改性后,炭黑填充胶的力学性能、耐磨性能均出现不同程度的降低。
Abstract:
Surface modification of traditional carbon black (CB) was adopted by three methods, and the changes about the surface morphology and structure of CB before and after modification were investigated, and the modified CB was used to fill natural rubber (NR)/polybutadiene rubber (BR) blend. The effects of modified CB on the mechanical properties, curing characteristics, and dynamic mechanical properties of composites were investigated. The results showed that compared with the unmodified CB, the surface roughness of CB increased after refining particle size, raising the pH value and lignin modification. The refined CB had the higher specific area, and much more loose secondary structures for the CB with high pH value, as well as the increased particle size in lignin system slightly. For the CB filled NR/BR blend, refining particle aize and raising pH value could promote its mechanical properties, wear resistance and wet skid resistance significantly, but make an obvious vulcanization delay effect. After modification by lignin, the vulcanized blend filled with CB presented a lower mechanical properties and wear resistance varyingly.
