一种耐高温密封胶条的制备工艺
技术领域
本发明涉及胶条制备领域，特别是涉及一种耐高温密封胶条的制备工艺。
背景技术

为此，我们提出了一种耐高温密封胶条的制备工艺解决上述问题。

优选的，所述S1中对备料1和2中各原料采用同规格，近似规格的原料颗粒，同时采用滚筒式混合设备对原料进行混合。
优选的，所述硫化机共设三组，每组硫化机的长度为10-20m，三组硫化机之间间隔排布，间距为1-1.5m，胶条组合体在硫化机内的通过速度为0.5m-1.5m/s。
优选的，所述冷却水槽为循环供水，低温水体以下进上出的方式在冷却水槽内循环，组合胶条置于冷却水槽内中部位置处。
优选的，所述S6后增设S6.1、磨边，经冷却后的组合胶条导入至磨边设备内，对挤出成型过程中产生的毛边进行打磨，使组合胶条两侧边缘处光滑，再通过鼓风机风干打磨后的组合胶条。
与现有技术相比，本发明能达到的有益效果是：

附图说明
图1为本发明的组合胶条示意图。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体实施例，进一步阐述本发明，但下述实施例仅仅为本发明的优选实施例，并非全部。基于实施方式中的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得其它实施例，都属于本发明的保护范围。下述实施例中的实验方法，如无特殊说明，均为常规方法，下述实施例中所用的材料、试剂等，如无特殊说明，均可从商业途径得到。
实施例1

备料2，准备氟橡胶55-85份，炭黑滑石粉混合填充剂30-60份，增塑剂15-25份，将上述原料充分混合。
所述S1中对备料1和2中各原料采用同规格，近似规格的原料颗粒，同时采用滚筒式混合设备对原料进行混合，同规格和近似规格的原料以滚筒混合的方式可减少小颗粒原料的沉降，使各原料均匀的混合。
丁晴橡胶和氯丁橡胶的组合模式可赋予成型后的胶条良好的耐油耐溶剂性，作为组合胶条的内基层，方便与不同的安装介质连接，减少安装介质上附着物对密封胶条的侵蚀。
氟橡胶可赋予成型后的胶条较好的阻热耐热性，作为外部保护铠装。

S6、冷却干燥，经硫化处理后的组合胶条导入至冷却水槽内冷却，在冷却后再次导出，所述冷却水槽为循环供水，低温水体以下进上出的方式在冷却水槽内循环，组合胶条置于冷却水槽内中部位置处，不断向上流动的水体可迅速带走胶条上的热量；
所述S6后增设S6.1、磨边，经冷却后的组合胶条导入至磨边设备内，对挤出成型过程中产生的毛边进行打磨，使组合胶条两侧边缘处光滑，再通过鼓风机风干打磨后的组合胶条，导出位置处设鼓风机，对残留在组合胶条上的水渍进行风干，风干的过程中，打磨时产生的碎屑可被一并去除。
S7、收纳绕卷，将风干后的组合胶条导入至收卷机内进行收卷。
