Abstract

本发明公开了一种发动机外漆喷涂方法，包括以下步骤：a. 将发动机外壳放入到盐酸池里面浸泡1h，然后用清水清洗10—20min，在放入脱脂池里面浸泡40—60min，在放入到磷化池里面浸泡50—70min，随即取出放入钝化池里面浸泡30—50min，使用工业酒精进行擦拭，最后使用清水冲洗1—3遍；b. 对发动机外壳进行火焰处理或电晕放电的活性基团的表面处理，以增强表面吸附能力；c. 在发动机外壳的喷涂部位预涂底漆，底漆采用硅橡胶预涂底漆，喷涂时采取外壳沿轴向旋转，并且同时进行喷涂的方式，使喷涂轨迹为圆环；d. 将喷涂有预涂底漆的发动机壳体置于室内，在室温下固化12h后喷涂隔热涂层。采用本发明能够有效提高涂层的稳定性。

Description

一种发动机外漆喷涂方法
技术领域
本发明涉及发动机制造领域，具体而言，是一种发动机外漆喷涂方法。
背景技术
目前，不论是运用于航天航空，还是汽车等运载器具，发动机必然会要承受高温高热。而为了提高发动机的耐热性能，多采用在发动机外表面喷涂隔热涂料、防静电底漆形成保护涂层，但现有的大多数工艺制作的涂层质量稳定性差，涂装效率低。
发明内容
本发明旨在提供一种发动机外漆喷涂方法，以解决上述问题。
为实现上述目的，本发明的技术方案如下：
一种发动机外漆喷涂方法，其特征在于，包括以下步骤：
a. 将发动机外壳放入到盐酸池里面浸泡1h，然后用清水清洗10—20min，在放入脱脂池里面浸泡40—60min，在放入到磷化池里面浸泡50—70min，随即取出放入钝化池里面浸泡30—50min，使用工业酒精进行擦拭，最后使用清水冲洗1—3遍；
b. 对发动机外壳进行火焰处理或电晕放电的活性基团的表面处理，以增强表面吸附能力；
c. 在发动机外壳的喷涂部位预涂底漆，底漆采用硅橡胶预涂底漆，喷涂时采取外壳沿轴向旋转，并且同时进行喷涂的方式，使喷涂轨迹为圆环；
d. 将喷涂有预涂底漆的发动机壳体置于室内，在室温下固化12h后喷涂隔热涂层。
进一步地，所述底漆的涂层厚度为130μm-150μm。
本发明的有益效果在于：本发明提高了外壳表面的吸附能力，加强了涂层的稳定性。
具体实施方式
下面结合具体实施例对本发明做进一步说明。
