一种橡胶用石墨烯复合硫化促进剂及其制备方法
摘要：
本发明涉及一种橡胶用石墨烯复合硫化促进剂及其制备方法。本发明将质量百分比为50~80%的橡胶促进剂TBBS分散于有机溶剂或水中，搅拌均匀，形成分散液；向分散液中加入质量百分比为20~50%的石墨烯，超声分散30~60min；然后过滤、干燥，得到橡胶用石墨烯复合硫化促进剂。本发明的橡胶用石墨烯复合硫化促进剂能够降低胶料的门尼粘度，延长门尼焦烧时间，提高胶料的拉伸性能，且工艺简单、易操作。
摘要（英）：

The invention relates to a graphene composite vulcanization accelerator for rubber and a preparation method thereof. The method includes: dispersing a rubber accelerator TBBS with a mass percentage of50-80% in an organic solvent or water, and stirring the substances evenly to form a dispersion liquid; adding 20-50% by mass of graphene into the dispersion liquid and conducting ultrasonic dispersion for 30-60min; and then performing filtering and drying so as to obtain the graphene composite vulcanization accelerator for rubber. The graphene composite vulcanization accelerator for rubber provided by the invention can reduce the Mooney viscosity of the rubber material, prolong the Mooney scorch time and improve the tensile properties of the rubber material, and the process is simple and is easy to operate.
