Use of natural Oils as potential Additives in filled Rubber Compounds for antistatic Applications

摘要

The effect of natural oils (castor and jojoba oils) as alternative ingredient for NBR and NR vulcanizates has been evaluated. Only for comparison, DOP is used as a reference plasticizer. The mechanical properties revealed that castor oil and jojoba oil act as a plasticizer in the range > 6 phr. The presence of oils led to a fine distribution of the SiO2 inside both rubbers. In addition, NBR/SiO2 vulcanizates showed good thermal stability due to the formation of intermediate, thermally stable structures as a result of thermo-oxidative reactions of natural oils. The electrical conductivity values are found to be in the order of 10(-9) S/cm which highly recommends such composites to be used as antistatic materials.
