Description

一种耐臭氧性能的橡胶密封条
技术领域
本发明属于橡胶技术领域，尤其是涉及一种耐臭氧性能的橡胶密封条。
背景技术
臭氧主要存在于大气层中同温层之下的臭氧层中(距离地表20公里)，但在地表大气中也存在稀薄的臭氧。因为橡胶材料对臭氧的敏感特性，即使是稀薄的臭氧，也会让所有的橡胶制品出现龟裂的情况。如何提高产品的国际市场竞争力，如何提高橡胶的性能参数，将是橡胶行业未来的研究方向。
发明内容
本发明公开了一种耐臭氧性能的橡胶密封条，它由下列重量份数的原料制成：三元乙丙胶95～105份、炭黑90～100份、芳烃油10～20份、氧化锌5～12份、硬脂酸0.5～2份、UPE粉5～10份、硫磺2～4份、四硫化双戊撑秋兰姆1～3份、N-叔丁基-2-苯并噻唑次黄酰胺1～3份、二正丁基二硫代氨基甲酸锌1～3份、微晶石蜡3～5份。
具体实施方式
结合实施对本发明作进一步详述，一种耐臭氧性能的橡胶密封条，它由下列重量份数的原料制成：三元乙丙胶95～105份、炭黑90～100份、芳烃油10～20份、氧化锌5～12份、硬脂酸0.5～2份、UPE粉5～10份、硫磺2～4份、四硫化双戊撑秋兰姆1～3份、N-叔丁基-2-苯并噻唑次黄酰胺1～3份、二正丁基二硫代氨基甲酸锌1～3份、微晶石蜡3～5份。
一种耐臭氧性能的橡胶密封条的生产方法，包括以下步骤：
1、对橡胶条的组成原料按照各自的质量百分比分别称重。
2、将已称重的各种原料投入到密炼机中混炼，将气压调节至0.5Mpa，温度保持在120℃，混炼持续时间400秒。
3、在开炼机上将混炼胶压片冷却，其中辊间间隙0.2mm，片材厚度10～13mm、宽度100～130mm。
4、设置挤出机温度为螺杆75℃、机头95℃，转速调整到60转/分，按设计模具挤出产品。
5、将挤出产品进行加热硫化，使加热箱温度保持在260℃，持续时间为100秒。
6、将硫化好的产品经冷水槽进行定型。
7、牵引、打盘、包装。
本发明的有益效果是：1、本发明生胶采用三元乙丙橡胶，材料来源广泛，成本低廉，加工方便，能大规模生产。2、本发明所提供的改善耐臭氧性能的橡胶密封条，具有卓越的耐臭氧性能，使产品的耐用性得到了数倍的提升，从而提高橡胶密封条的物理机械性能和使用寿命。
