摘　　要：本文通过氮气排凝、氮气不排凝两种工艺方式,运用硫化测温技术,测定轮胎各部位硫化程度与温度动态差,进一步检验成品轮胎的性能优异度。经过研究发现,两种方式均存在由温度变化引起的过硫现象,但在氮气排凝中轮胎各部位温度变化更小。在DSC数据分析下,氮气排凝的硫化程度更低;在RPA变温分析下,氮气排凝的过硫程度更低;在检测成品轮胎的性能中,氮气排凝生产的轮胎的各项指标更优。In this paper,through the two methods of nitrogen decondensation and nitrogen non-decondensation,the curing temperature measurement technology was used to determine the curing degree and temperature dynamic difference of each part of the tire,and further test the performance of the finished tire.It is found that there is a phenomenon of over sulfur caused by the temperature change in both ways,but the temperature change in each part of the tire is smaller in nitrogen decondensation.Under the analysis of DSC data,the curing degree of nitrogen decondensation is lower.Under RPA variable temperature analysis,the degree of persulfation of nitrogen decondensation is lower.In the performance test of finished tires,the indexes of tires produced by nitrogen decondensation are better.
