硫化时间及硫化体系对粘土胶热氧老化性能的影响 杨丹 敖宁建 杨世柱 摘要:用热空气老化试验和热分析法讨论了硫化时间和硫化体系对粘土胶热氧老化性能的影响。结果表明,粘土胶由于热氧性能敏感,在硫化曲线允许的范围内,硫化时间以20min为宜。采用有效硫化体系和半有效硫化体系硫化粘土胶可以使其具有较好的热氧老化性能。 Effect of vulcanization time and vulcanization system on thermal ageing property of clay-rubber masterbatch Yang Dan Abstract:The effect of
vulcanization time and vulcanization systems on thermal ageing property of the clay-rubber
masterbatch were investigated by air oven ageing test and thermal analysis.The results
showed that the optimum vulcanization time of the clay-rubber masterbatch was 20 min in
the range of vulcanization curve,because of its sensitivity to thermal ageing.When the
clay- rubber masterbatch was vulcanized by semi-efficient vulcanization system and
efficient vulcanization system,better thermal ageing resistance could be obtained. 基金项目:国家自然科学基金资助项目(5963001);海南省自然科学基金资助项目(59601)。 参考文献 1,柯舍列夫ФФ,柯尔涅夫АМ,布卡诺夫АЕ.橡胶工艺学[M].江畹兰,王秀华,韩淑玉,等译.陕西:陕西科学技术出版社,1986.203 收稿日期:1999-10-07 |
