Description

一种汽车用模压注射海绵橡胶密封条
技术领域
本发明涉及橡胶材料技术领域，具体涉及一种汽车用模压注射海绵橡胶密封条。
背景技术
汽车车门密封条上的海绵橡胶材料，汽车车门密封条目前主要是由EPDM橡胶生产的发泡海绵密封条，安装在汽车车门钣金上，在车门关闭状态下和门框挤压在一起起到密封的作用，主要起到车门密封、防尘、防震和防噪声的作用，是汽车车门中不可缺少的组成部分，现有车门密封条的生产是采用EPDM橡胶中添加化学发泡剂进行硫化发泡制得的海绵配方。目前传统的海绵密封胶条在接角的位置处，通常都是采用与直段密封胶条不相同的密实胶进行接角，这种密封胶条在安装于汽车车门时，关门的时候由于各个部位的挤压力不同，而导致车门关好后的密封性不够强，同时车门的边沿的密封胶条的手感极差，给正常的使用造成了一定的影响，而且加工也相对比较耗费材料，间接地增加了更多的污染产物。
发明内容
本发明的目的在于克服上述不足，提供了一种汽车用模压注射海绵橡胶密封条，在一定程度上降低了污染产物的量，同时能够保证产品的在使用的过程中有极好的密封性能，又有着很好的手感，降低了厂家的加工成本。
本发明的目的是这样实现的：
一种汽车用模压注射海绵橡胶密封条，包括以下质量份数的原材料：EPDM生胶为100份、补强剂炭黑N550为60-80份、石蜡油为60-80份、氧化锌为3-10份、硬脂酸为1-3份、表面活性剂为1-5份、分散剂为1-4份、油膏为2-3份、吸湿剂为6-12份、硫化剂为1-2份、促进剂为2-3份、发泡剂为6-12份。
优选的，所述油膏和发泡剂的质量份之比为1:3-4。
优选的，所述发泡剂为ADC和OBSH两种混合。
优选的，所述ADC和OBSH质量份之比为1:0.5-1。
优选的，所述促进剂为ZDBC、TMTD、TETD和CZ和DTDM的一种或多种混合。
优选的，所述促进剂为ZDBC、TMTD、TETD、CZ和DTDM五种混合。
优选的，所述EPDM生胶的门尼粘度为8-10。
优选的，所述硫化剂采用硫磺硫化体系。
本发明的有益效果是：
本发明在一定程度上降低了污染产物的量，同时能够保证产品的在使用的过程中有极好的密封性能，又有着很好的手感，降低了厂家的加工成本。
具体实施方式
实施例1：

实施例3：
一种汽车用模压注射海绵橡胶密封条，包括以下质量份数的原材料：EPDM生胶为100份、补强剂炭黑N550为80份、石蜡油为80份、氧化锌为10份、硬脂酸为1份、表面活性剂PEG-4000为3份、分散剂WB-16为1份、油膏为2.5份、吸湿剂为12份、硫磺粉为2份、ZDBC为1.5份、TMTD为1.5份、TETD为1份、CZ为1份、DTDM为1份、ADC为4份、OBSH为4份。
对比例1：
与实施例1相同，除了将质量份ADC为6份、OBSH为6份替换成只加入ADC为6份。
对比例2：
与实施例1相同，除了将质量份ADC为6份、OBSH为6份替换成只加入OBSH为6份。
对比例3：
与实施例1相同，除了不加入任何发泡剂。
对比例4：
与实施例1相同，除了不加入油膏。
将实施例1-3与对比例1-4进行性能比较，见下表：
实施例1 实施例2 实施例3 对比例1 对比例2 对比例3 对比例4
密度 0.61 0.70 0.66 0.65 0.75 1.12 0.68
外观 光滑细腻 光滑细腻 光滑细腻 光滑细腻 光滑细腻 光滑细腻 不光滑细腻
气味 无异味 无异味 无异味 有刺激性气味 有刺激性气味 有刺激性气味 有刺激气味
