Jatropha seed oil (JSO) is renewable oil with unique characteristics including a high flash point, low viscosity and saponification value, and a solubility parameter close to that of natural rubber. The incorporation of JSO and its epoxidized derivatives containing 50% (EJSO‐50) and 100% mole epoxide groups (EJSO‐100) in carbon black‐filled natural rubber was compared with the incorporation of paraffinic, naphthenic, and treated distillate aromatic extract oils in a range of 2–10 phr. The results showed that JSO promoted good rubber processability similar to that achieved with paraffinic and naphthenic oils, with the advantages of the shortest cure time and scorch time. However, it was found that the epoxide groups especially in EJSO‐100 can interfere in the vulcanization reaction resulting in poorer cure behaviors and mechanical properties. The abrasion resistance of the rubber containing JSO was the highest and progressively improved in a range of 4–8 phr. Moreover, using the various oils at this range of values can improve filler dispersion, sustain the tensile properties, and achieve a balance between wet grip and rolling resistance. J. VINYL ADDIT.

炭黑增强天然橡胶中基于麻风树籽油及其环氧化衍生物的生物加工助剂

麻风树籽油（JSO）是可再生油，具有独特的特性，包括高闪点，低粘度和皂化值以及接近天然橡胶的溶解度参数。将JSO及其包含50％（EJSO-50）和100％摩尔环氧基团（EJSO-100）的环氧化衍生物在炭黑填充天然橡胶中的掺入与石蜡，环烷烃和经处理的馏出芳烃提取油的掺入进行了比较在2-10 phr范围内。结果表明，JSO促进了与石蜡和环烷油相似的良好橡胶加工性能，具有硫化时间和焦化时间最短的优势。但是，发现环氧基尤其是EJSO-100中的环氧基会干扰硫化反应，从而导致较差的固化行为和机械性能。含JSO的橡胶的耐磨性最高，并且在4-8 phr范围内逐渐提高。此外，在该值的范围内使用各种油可改善填料分散性，维持拉伸性能，并在湿抓地力和滚动阻力之间达到平衡。J.乙烯基添加物。TECHNOL。，26：62–76，2020.©2019塑料工程师协会
