Substitution of petroleum‐based processing oils with eco‐friendly sustainable plasticizers in rubber compounds has gained much global attention due to their toxicity. In this regard, so far, the major attempts have focused on substituting aromatic oils with fatty acid based vegetable oils. In this work, the chemical and physical effects of canola oil as a model of fatty acid based vegetable oils on the process‐ability, vulcanization kinetics, and final properties of carbon‐black filled styrene–butadiene rubbers are systematically investigated. In contrast to the previous studies, it was shown that although these types of vegetable oils have a plasticizing impact, they can indeed threaten the requirements of reinforcing criteria in rubber vulcanizates. The final properties of the vulcanizates were found to be deteriorated due to the incompatibility of canola oil fatty acids constituents with rubber matrix and especially as a result of chemical interference of their unsaturated bonds in sulfur vulcanization kinetics.

洞察植物基增塑剂对填充橡胶硫化胶性能的相容性

由于其毒性，用生态友好的可持续增塑剂代替石油基加工油已引起了全球的广泛关注。在这方面，到目前为止，主要的尝试集中在用脂肪酸基植物油代替芳族油。在这项工作中，系统地研究了低芥酸菜子油（作为脂肪酸基植物油的模型）对炭黑填充丁苯橡胶的加工性能，硫化动力学和最终性能的化学和物理影响。与以前的研究相反，研究表明，尽管这些类型的植物油具有增塑作用，但它们的确可以威胁到橡胶硫化橡胶中增强标准的要求。
