Abstract

A series of new environment-friendly plasticizers was synthesized from castor oil and used to plasticize nitrile rubber (NBR). The test results showed that tensile strength, elongation at break, and tear strength of NBR vulcanizates plasticized by castor oil-based plasticizers were found to be better than that of dioctyl phthalate (DOP). The aging test taken demonstrated that the castor oil-based plasticizers could improve the hot air and oil aging resistance of NBR vulcanizates. The thermal stability test illustrated that castor oil-based plasticizers enhanced the thermal stability of NBR vulcanizates, and the initial decomposition temperatures (T) were about 100 °C higher than that of DOP. In general, the studies manifested that EACO and EBCO can replace DOP to plasticize NBR and are used in fields that require high mechanical properties, aging resistance, and thermal stability. This study emphasizes the effects of sustainable, cost-effective, and high-efficiency plasticizers on NBR.

摘要

一系列新型环保增塑剂由蓖麻油合成，并用于增塑丁腈橡胶（NBR）。测试结果表明，用蓖麻油基增塑剂增塑的NBR硫化胶的拉伸强度、断裂伸长率和撕裂强度均优于邻苯二甲酸二辛酯（DOP）。进行的老化试验表明，蓖麻油基增塑剂可提高NBR硫化胶的耐热空气和耐油老化性能。热稳定性测试表明，蓖麻油基增塑剂提高了NBR硫化胶的热稳定性，初始分解温度（T）比DOP高约100℃。总体而言，研究表明EACO和EBCO可替代DOP增塑NBR，并用于需要高机械性能、耐老化性和热稳定性的领域。本研究强调了可持续、经济高效的增塑剂对NBR的影响。
