摘　　要：通过改变不同配方的氟橡胶二段硫化温度和时间,确定了最佳硫化条件。结果表明,氟橡胶经二段硫化后力学性能明显提高;经300℃热空气老化后发现,不同二段硫化条件对氟橡胶的耐热性有着不同的影响。The optimum post curing conditions of fluoro rubber blends were determined by changing the temperature and the time. The results showed that the mechanical properties of post cured fluoro rubber were significantly improved. It was found that the effects of the different curing conditions on the heat risistance of fluoro rubber were different at 300℃ hot air ageing.
