进一步,所述的骨架与主料的体积比为1:6。
一种镂空贴合式密封橡胶材料的制备方法,步骤如下:
S1、将主料中的丁腈橡胶、丙烯酸酯橡胶、环氧树脂、偏苯三酸酯按照重量份称取,然后加入密炼机中进行密炼,得到密炼好的胶料;
S2、将密炼好的胶料投入到开炼机中,然后按照重量份称取三氧化二铝、聚酰亚胺树脂、白炭黑、防老剂、硫磺投入到开炼机中进行混炼,压制成型,形成预成型橡胶;
S3、将石墨烯内芯上均匀切割出多个贴合孔,形成骨架;
S4、取两片预成型橡胶和骨架置于复合机上进行热压复合,形成预成型橡胶-骨架-预成型橡胶的夹心式密封橡胶材料结构;骨架两侧的预成型橡胶通过贴合孔间隔形贴合对接;
S5、将预成型橡胶-骨架-预成型橡胶的夹心式密封橡胶材料结构放入到硫化设备中的模具内,进行硫化处理,通过切割机进行切割修边后得到密封橡胶材料。

进一步,所述步骤S5中的硫化温度为160~170℃,硫化时间为25~35min,硫化压力为15~25Mpa。
本发明的有益效果
本发明改变了传统的橡胶密封件的结构,本发明在橡胶密封件的内部增设了骨架,并且骨架是一块石墨烯内芯,石墨烯的机械强度高,而且具备很强的韧性,作为密封性橡胶的内部骨架再合适不过,但是石墨烯内芯润滑性比较好,和胶料的粘接性太差,于是本发明在石墨烯内芯上切割多个均匀分布的贴合孔,使得在热压复合工艺中骨架两侧的预成型橡胶通过贴合孔间隔形贴合对接,使得整个结构更加的稳固,整个结构不但强度和韧性得到了提升,而且连接的更加牢固稳定,本发明的橡胶密封件的结构以及制备方法属于橡胶密封件领域的首创,应用前景广泛。
