Description

一种车用复合材料密封条的制造方法
技术领域
本发明涉及汽车零配件技术领域，具体而言，涉及一种车用复合材料密封条的制造方法。
背景技术
汽车门窗中的密封条是汽车门窗上必不可少的配件，它依靠密封条的压缩变形来弥补汽车门窗的缝隙，起到密封和减震作用。汽车门窗密封条可以防止外部的风、雨及尘土等有害物质侵入车内，减少汽车在行驶中门、窗等部位产生的振动，能缓和车门关闭时的冲击力，还能提高隔音和隔热效果。此外，汽车前后门窗的密封条可以防止车辆在高速行驶时气流产生的噪音，提高整车的舒适性。
目前的密封条摩擦系数较高，在长期使用过程中易发生弹性消失、老化等形象，严重影响其密封性能和减震性能。而且密封条内的金属骨架易发生锈蚀，影响密封条的强度和外观，有时还会使车身上对应密封条处出现锈渍。故研制了克服上述缺陷的密封条，现需提供一种制备该改进密封面的制造方法。
发明内容
本发明的目的在于提供一种车用复合材料密封条的制造方法，以解决现有的密封条存在的上述问题。
为实现本发明目的，采用的技术方案为：一种车用复合材料密封条的制造方法，包括以下步骤：
A.加工制得金属骨架，金属骨架浸入防锈液中，经加热固化在金属骨架的表面形成防锈涂层；
B.制备弹性体，并将其液体原料按照密封条外轮廓形状注塑成型；
C.制备胶水，并将胶水进行加热，加热温度为60-100℃，并保温30s，而后立即放置到脱泡机中进行真空脱泡，脱泡时间为5min；
D.将胶水涂覆至金属金属骨架外，放置5min后进行加热；将弹性体粘接在加热后的金属骨架上。
进一步地，所述弹性体由下述质量份的物质制备而成：三元乙丙橡胶K4869:30～60份，三元乙丙橡胶3072EM:15～25，高岭土:3～7，氧化锌:4～7，硬脂酸:1.5～2.5，分散剂L-24:0.5～1.2，聚乙二醇:1.5～2.5，GPF 级炭黑N550:35～55，重质碳酸钙:15～20，石蜡油:21～30，发泡剂:0.5～1.1，促进剂:1.3～1.7，防焦剂CTP:0.06～0.12，硫磺:0.5～1.22；金属骨架外表面具有防锈涂层。
进一步地，所述防锈涂层由下述质量份的物质制备而成：硅酸盐水泥:12-25份，硅烷偶联剂KH570:3-5份，氯化石蜡:2-3份，聚酯乳液:15-25份，苯丙乳液:20-25份，过氧化甲乙酮固化剂:0.08-0.15，自来水:30-50份。
本发明的有益效果是，加工简单，成本低，而且制作周期短，在制造过程中便于分别对金属骨架和弹性体的质量控制，胶水的处理增加了弹性体与金属骨架的连接性能，保证其整体的使用寿命。制得的密封条摩擦系数低，具有良好的密封性能、机械性能以及减震性能，不易出现开裂老化，安全环保，有效防止其锈蚀，不会影响外观，且保证了较高的强度。
