中文摘要:
      应用RPA2000橡胶加工分析仪测试炭黑胶料在一定条件下弹性模量的变化,研究炭黑聚集的过程。结果表明,在没有硫化体系或胶料交联前,炭黑的聚集速度很快,而且是一个持续过程,炭黑的聚集速度随着温度的升高而加快。对于终炼胶,炭黑的聚集在硫化交联之前已经开始;在相同的硫化程度下,低温硫化胶料的Payne效应较高,炭黑聚集程度较大;胶料的门尼粘度越高,炭黑的聚集速度越慢,聚集程度越小。
英文摘要:
      RPA2000 rubber processing analyzer was used to test the change of elastic modulus of carbon black filled compound in some condition,and to study the process of carbon black aggregation.The results showed that the aggregation speed of carbon black was fast and continuoused without curing system or before crosslinking.The aggregation speed of carbon black increased with the rise of temperature.For final stock,the aggregation of carbon black began before vulcanization and crosslinking;at the same vulcanization degree,the Payne effect of low temperature vulcanizate was higher and the aggregation degree was more serious;the higher the Mooney viscosity of the compound,the slower the aggregation speed of carbon black and the lower the aggregation degree.
