Abstract

本发明公开了耐疲劳橡胶，所述的橡胶含有以下物质：天然橡胶、氧化锌、硬脂酸、防老剂、莱茵蜡、高耐磨碳黑、炭黑N774、环烷油、防焦剂、硫磺、N-氧二乙撑基-2-苯骈噻唑次磺酰胺、二甲基二硫代氨基甲酸锌，本发明与现有技术相比，用此橡胶配方生产出的隔振块具有良好的耐热老化、耐撕裂、生热低、抗动态疲劳性能优异的特点。

Description

耐疲劳橡胶
技术领域
本发明涉及橡胶，具体涉及用于隔振块的耐疲劳橡胶。
背景技术
正常汽车使用的液压减震器的使用寿命最低是180～220万次，用橡胶制备的隔振块与液压减震器是配套使用，现有的隔震块的使用寿命往往只能达到120万次，满足不了隔振块的需要。
发明内容
本发明所要解决的技术问题是提供一种用于使隔震块的使用寿命能够达到160万次以上的耐疲劳橡胶。
本发明解决技术问题的技术方案为：耐疲劳橡胶，含有以下重量份的物质：
Figure BDA0000085660020000011
Figure BDA0000085660020000021
优选的耐疲劳橡胶，含有以下重量份的物质：
Figure BDA0000085660020000022
所述的防老剂的型号为4020，由台湾顺聚公司生产。
所述的防焦剂的型号为CTP，由博兴科源新材料有限责任生产。
本发明的橡胶制备方法与现有的制备方法相同。
本发明中，中超高耐磨碳黑、与碳黑N774、天然胶之间的比例非常重要，大于或小于上述配比，使用寿命均达不到150万次。
本发明与现有技术相比，用此橡胶配方生产出的隔振块具有良好的耐热老化、耐撕裂、生热低、抗动态疲劳性能优异的特点。
