摘要
对未改性酚醛树脂、妥尔油改性酚醛树脂和腰果油改性酚醛树脂在子午线轮胎三角胶中的应用进行对比研究。结果表明:与未改性酚醛树脂胶料相比,妥尔油改性酚醛树脂胶料和腰果油改性酚醛树脂胶料的密炼能耗和密炼升温速率较低,门尼焦烧时间和正硫化时间较长,硫化速度较慢,抗硫化返原性能提高,10%定伸应力和30%定伸应力较大,耐老化性能改善;妥尔油改性酚醛树脂胶料的综合性能较好。
The application of unmodified phenolic resin, tall oil modified phenolic resin and cashew nut oil modified phenolic resin in the apex compound of radial tire was comparatively investigated. The results showed that compared with the compound with unmodified phenolic resin, the energy consumption for mixing and temperature increase during the mixing of the compounds with tall oil modified phenolic resin or cashew nut oil modified phenolic resin were lower, the Mooney scorch time and curing time were longer, the curing speed was slower, the anti-reversion performance was better, the modulus at 10% and 30% elongation were higher, and the aging resistance was better. The overall performance of the compound with tall oil modified phenolic resin was better.
