Abstract

本发明公开了一种耐高温低成本的乙丙橡胶，由以下重量份的成分组成：二元乙丙橡胶 10～30；三元乙丙橡胶10～20；硫化剂3～6；氧化锆5～8；聚酰胺蜡微粉6～10；乙炔炭黑10～12；纳米凹凸棒土2～4；机油3～5。采用二元乙丙橡胶与三元乙丙橡胶并用，通过调整硫化体系使得二元乙丙橡胶与三元乙丙橡胶共硫化，能达到耐高温的要求，而且胶料获得了较低的压缩永久变形，硫化产品具有良好的耐热性、化学稳定性和低的压缩变形，采用白炭黑和酚醛树脂，改善了胶料的加工流动性。

Description

一种耐高温低成本的乙丙橡胶
技术领域
本发明涉及橡胶材料技术领域，尤其涉及一种耐高温低成本的乙丙橡胶。
背景技术
随着橡胶行业的不断发展，橡胶制品的使用条件日益苛刻，对耐热提出了更高的要求，很多橡胶管、密封件等橡胶制品要求长期耐高温150℃。乙丙橡胶具有突出的耐热，耐过热水蒸汽，耐臭氧、耐天侯老化及高绝缘等性能，尤其耐热老化性能好，但是传统硫化体系乙丙橡胶一般耐温能达到125℃，当温度达到150℃时, 橡胶制品的压缩变形随之增大,以至于不能正常工作，使其在长期高温使用过程中出现质量问题。
发明内容
针对现有技术存在的不足，本发明所要解决的技术问题是，提供一种机械、物理性能好，能够很好满足制品对橡胶材料耐高温、低压变条件的要求的耐高温低成本的乙丙橡胶。
为解决上述技术问题，本发明所采取的技术方案是：一种耐高温低成本的乙丙橡胶，由以下重量份的成分组成：
二元乙丙橡胶                     10～30；
三元乙丙橡胶                     10～20；
硫化剂                            3～6；
氧化锆                            5～8；
聚酰胺蜡微粉                      6～10；
乙炔炭黑                          10～12；
纳米凹凸棒土                      2～4；
机油                               3～5。
本发明耐高温低成本的乙丙橡胶的优点是：采用二元乙丙橡胶与三元乙丙橡胶并用，通过调整硫化体系使得二元乙丙橡胶与三元乙丙橡胶共硫化，能达到耐高温的要求，而且胶料获得了较低的压缩永久变形，硫化产品具有良好的耐热性、化学稳定性和低的压缩变形，采用白炭黑和酚醛树脂，改善了胶料的加工流动性。
具体实施方式
下面结合具体实施例对本发明做进一步详细说明；
一种耐高温低成本的乙丙橡胶，由以下重量份的成分组成：
二元乙丙橡胶                     10～30；
三元乙丙橡胶                     10～20；
硫化剂                            3～6；
氧化锆                            5～8；
聚酰胺蜡微粉                      6～10；
乙炔炭黑                          10～12；
纳米凹凸棒土                      2～4；
机油                               3～5。
当然，上述说明并非是对本发明的限制，本发明也并不限于上述举例，本技术领域的普通技术人员，在本发明的实质范围内，作出的变化、改型、添加或替换，都应属于本发明的保护范围。
