Description

一种具有碳纤维编织层的橡胶软管及包覆硫化方法 技术领域
本发明涉及橡胶制品技术领域,具体为一种具有碳纤维编织层的橡胶软管及包覆硫化方法。
背景技术
所谓橡胶软管,是钢丝编织胶管。胶管由内胶层,一层钢丝编织层和外胶层组成。适用于输送液压流体,如醇,燃油,润滑油,乳化液等等。与硬管相区分,(橡胶)软管最大的特征是可弯曲性。根据使用工况和性能要求的差异软管的设计千差万别,常见的参数有尺寸、压力、重量、长度、弯曲度、化学耐用性等。相比民用软管,工业作业环境更复杂、更恶劣、设备对输送管的要求也更苛刻,因此工业软管从设计、对材料的选择到生产、运输甚至最终的储存都有严格的规范和标准。但是现有的橡胶软管采用钢丝编织层,其耐磨性、耐腐蚀性较差,此外一些软管还比较坚硬,抗拉强度较低、不耐高温的问题,常常使用不方便。
硫化是橡胶制品生产的最后一个工艺过程,也是橡胶加工的主要工艺之一,在橡胶软管生产中,硫化是使橡胶与补强层之间具有较高的粘合强度,使之成为一个整体的重要工艺,也是保证和提高产品质量的重要环节。传统的硫化方法是在软管硫化前在其半成品上缠水包布或包铅紧固,于蒸汽硫化罐中分批进行。包水包布硫化虽然也能增加软管的致密性,但其外观不好。一般采用包铅硫化可以使软管获得光滑的外表面,但是这种方法的一个重要缺点是存在严重的污染问题, 这是由于包铅工艺中所用铅块在熔融和硫化过程中极易氧化,并伴有铅蒸汽造成的污染,此外对橡胶软管本身的性能有所影响,高分子材料经改性处理用作橡胶软管包覆材料时减轻铅污染的途径之一,鉴于上述提到的问题,本发明设计一种具有碳纤维编织层的橡胶软管及包覆硫化方法,以解决上述提到的问题。
发明内容

S4:加热:对加热柱进行加热,管状包覆层收缩而紧固于橡胶软管半成品的外表面;
S5:硫化:然后将覆盖包覆层的橡胶软管置于一定温度和压力下的蒸汽硫化罐内进行硫化。
