Method for testing activation energy in rubber vulcanization process based on differential scanning calorimetry and application

The invention relates to a method for testing rubber compositions in the industries of tires, rubber products and the like, in particular to a method for testing activation energy in a rubber vulcanization process based on differential scanning calorimetry and application. According to the method, the differential scanning calorimetry is introduced, so that the heat change in the vulcanization process can be more accurately measured, and the test error caused by white carbon black flocculation is avoided. Therefore, the novel method not only provides more reliable and accurate activation energy data, but also can carry out measurement in a wider temperature range, and exceeds the limitation of the traditional vulkameter test. The method has the advantages that the activation energy during rubber vulcanization can be accurately tested, the influence of white carbon black flocculation is eliminated, the accuracy is good, and the operation is simple and convenient. 本发明涉及轮胎、橡胶制品等行业的橡胶组合物的测试方法，尤其涉及一种基于差示扫描量热法测试橡胶硫
