Description

一种三元乙丙橡胶密封胶圈
技术领域
本发明属于橡胶制备技术领域，尤其涉及一种三元乙丙橡胶密封胶圈。 
背景技术
现有的制作橡胶密封胶圈的工艺方法，包括混炼、挤出、硫化等工艺步骤，其中混炼步骤所采用的胶种为丁苯或天然橡胶，再配合硫磺、促进剂、氧化锌、硬脂酸、炭黑、轻钙、环烷油、防老剂等辅料。这种工艺制作的橡胶密封胶圈存在以下缺点：对介质和环境产生污染，耐候性、耐臭氧性、耐热性差，还缺乏良好的电绝缘性和耐化学介质腐蚀性。 
发明内容
本发明针对现有技术存在的不足，提供一种绿色环保、性能优良的三元乙丙橡胶密封胶圈。 
本发明解决上述技术问题的技术方案如下：一种三元乙丙橡胶密封胶圈，其组分按重量份数计为：三元乙丙橡胶100～195份、硫磺1.2份、促进剂2.6份、氧化锌3.5份、硬脂酸0.5～2份、炭黑70～60份、轻钙75份、环烷油35～10份、防老剂1份和防焦剂CTP1份。 
将上述组分经过常规的橡胶制备方法，即混炼、挤出和硫化工艺后，制得三元乙丙橡胶密封胶圈成品。 
本发明的有益效果是：本发明组成成分简单，原料廉价易得，制得的三元乙丙橡胶对介质和环境不产生污染，耐候性、耐臭氧性、耐热性显著增强，还具有良好的电绝缘性和耐化学介质腐蚀性。 
在上述技术方案的基础上，本发明还可以做如下改进。 
进一步，所述的促进剂为促进剂CZ或促进剂DM。 
进一步，所述的防老剂为防老剂4010NA或防老剂D。 
具体实施方式
以下对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。 
本发明实施例中所述的耐候性是指：采用CLM-SN-900A氙弧灯老化试验箱，将试样夹在定伸保持器上，并使试样的标线间距离从25mm拉伸至37.5mm，在标准试验条件下放置24h；然后将夹有试样的定伸保持器放入符GB/T18244中要求的CLM-SN-900A氙弧灯老化试验箱中，试验250h后取出，再在标准试验条件下放置4h,观测定伸保持器上的试样有无变形，并用8倍放大镜检查试样有无裂纹。 
所述的耐热性是指橡胶的最高使用温度，参照GB/T 3512-2001方法。 
所述的耐臭氧性是指：将试样暴露于密闭无光照的含有恒定臭氧浓度的空气和恒温的试验箱中,在24h内对试样进行检测,从试样表面发生的龟裂或其它性能的变化程度,以评定橡胶的耐臭氧老化性能，参照GB/T24134-2009方法。 
所述的电绝缘性是指：对橡胶试样施加不同级别的电压，能够承受高级别电压的试样为电绝缘性能优良。 
所述的耐腐蚀性是指：将试样浸入强腐蚀性试剂中，检测其变化，参照GB/T 1690-2006方法。 
实施例1 
一种三元乙丙橡胶密封胶圈，其组分按重量份数计为：三元乙丙橡胶100份、硫磺1.2份、促进剂CZ2.6份、氧化锌3.5份、硬脂酸0.5份、炭黑 70份、轻钙75份、环烷油35份、防老剂4010NA1份、防焦剂CTP1份。将上述组分经过常规的橡胶制备方法，即混炼、挤出和硫化工艺后，制得三元乙丙橡胶密封胶圈成品，其各项性能测试见表1。 
实施例2 
一种三元乙丙橡胶密封胶圈，其组分按重量份数计为：三元乙丙橡胶140份、硫磺1.2份、促进剂2.6份、氧化锌3.5份、硬脂酸1份、炭黑63份、轻钙75份、环烷油20份、防老剂4010NA 1份和防焦剂CTP 1份。将上述组分经过常规的橡胶制备方法，即混炼、挤出和硫化工艺后，制得三元乙丙橡胶密封胶圈成品，其各项性能测试见表1。 
实施例3 
一种三元乙丙橡胶密封胶圈，其组分按重量份数计为：三元乙丙橡胶195份、硫磺1.2份、促进剂DM2.6份、氧化锌3.5份、硬脂酸2份、炭黑60份、轻钙75份、环烷油10份、防老剂D1份、防焦剂CTP1份。将上述组分经过常规的橡胶制备方法，即混炼、挤出和硫化工艺后，制得三元乙丙橡胶密封胶圈成品，其各项性能测试见表1。 
表1  各个实施例与天然橡胶的性能对照表 
Figure BDA0000434110260000031
从表1中看出，与天然橡胶相比，本发明制得的三元乙丙橡胶的耐候性、耐臭氧性、耐热性显著增强，还具有良好的电绝缘性和耐化学介质腐蚀性。 
本发明可用其他的不违背本发明的精神或主要特征的具体形式来概述。因此，无论从哪一点来看，本发明的上述实施方案都只能认为是对本发明的说明而不能限制本发明，权利要求书指出了本发明的范围，而上述的说明并未指出本发明的范围，因此，在与本发明的权利要求书相当的含义和范围内的任何改变，都应认为是包括在权利要求书的范围内。
