摘　　要：在NBR/PVC为基体的浅色共混胶材料中加入白炭黑,探究改变作为补强剂的白炭黑用量对NBR/PVC浅色共混橡塑材料的硫化特性、力学性能和耐老化等性能的影响。结果表明:当白炭黑用量达到50 phr时,断裂伸长率为386%,硬度为70度,拉伸强度为13.3 MPa,耐寒性能良好,脆性温度为-48℃,耐油性符合GB/T 1690—2010的标准。Adding white carbon black to the light-colored NBR/PVC blend rubber material as the matrix, the effect of changing the amount of white carbon black as a reinforcing agent on the vulcanization characteristics, mechanical properties and aging resistance of NBR/PVC light-colored blend rubber-plastic materials was investigated. The results showed that when the amount of silica reached 50 phr, the elongation at break was 386%, the hardness was 70 degree,the tensile strength was 13.3 MPa, the cold resistance was good, the brittleness temperature was-48℃. Oil resistance conformed to the standard of GB/T 1690—2010.
