摘要
探究了不同填料类型白炭黑(255、175、M3KD)、油酸钾、纤维素纤维(CF)和黏胶纤维(VF)对丁腈橡胶基复合材料性能的影响。通过硫化特性、力学性能和磨耗性能测试,分析了不同填料填充量对复合材料硫化时间、定伸模量、拉伸强度、断裂伸长率等参数的影响。研究结果表明,白炭黑M3KD与油酸钾的协同补强作用对提高丁腈橡胶复合材料的综合性能具有显著优势。纤维填充量的增加会增强复合材料的刚性,但也导致断裂伸长率和拉伸强度的下降。此外,较低纤维含量的填充有助于提升硫化效率和材料的综合性能。质量份数为3份的纤维填充量表现出最佳的综合性能。
In this paper,the effects of different fillers such as carbon black(255,175,M3KD),potassium oleate,cellulose fiber(CF)and viscose fiber(CV)on the properties of NBR composites were investigated.The effects of filling amount on vulcanization time,constant elongation modulus,tensile strength and elongation at break were analyzed by testing vulcanization properties,mechanical properties and abrasion properties.The results show that the synergistic reinforcing effect of silica black M3KD and potassium oleate has significant advantages in improving the comprehensive properties of NBR composites.The increase of fiber filling will enhance the rigidity of the composite,but decrease elongation at break and tensile strength.In addition,the filling with lower fiber content helps to improve the vulcanization efficiency and the overall properties of the material.The fiber filling of 3phr shows the best overall performance.
