以异戊橡胶为基础,研究了高孔隙炉黑与石墨并用及不同增塑剂对硫化胶体积电阻率ρv的影响。少量添加硬脂酸和邻苯二甲酸二丁酯的二元填充硫化胶,其力学性能变化不大,ρv值有一定程度减小。变压器油增至40份(对100份生胶而言),可调节胶料的黏度,而硫化胶的ρv及强度的变化甚微。 Based on isoprene rubber, the effects of high porosity furnace black and graphite and different plasticizers on the volume resistivity ρv of vulcanizate were studied. A small amount of adding stearic acid and dibutyl phthalate binary vulcanizate, its mechanical properties change little, ρv value to a certain extent reduce. The transformer oil increased to 40 parts (for 100 parts of raw rubber), can adjust the viscosity of the rubber, and vulcanizates ρv and intensity changes little.
