The invention relates to a hydro-pneumatic spring surface treatment method which comprises the following steps: pre-treating the surface of a hydro-pneumatic spring to remove grease and moisture on the surface; coating the primer on the surface of the hydro-pneumatic spring, and carrying out flash-drying treatment; the surface, away from the hydro-pneumatic spring, of the primer subjected to flash-drying treatment is coated with finish paint, drying treatment is conducted, and a primer paint layer and a finish paint layer which are sequentially arranged on the outer surface of the hydro-pneumatic spring are obtained; the primer comprises epoxy resin, zinc powder, a curing agent, a solvent and the like. A paint layer formed on the surface of the hydro-pneumatic spring through the technology is good in binding force, not prone to falling off, good in service effect and capable of achieving a good protection effect. The invention further provides the hydro-pneumatic spring, the automobile suspension structure and application, and due to the fact that the hydro-pneumatic spring has longer service time and more stable working conditions, the operation stability and application of the automobile suspension structure can be better improved.

    本申请涉及一种油气弹簧表面处理方法,包括以下步骤:对油气弹簧表面进行前处理,去除表面油脂和水分;将底漆涂布于油气弹簧表面,进行闪干处理;于经过闪干处理的底漆远离油气弹簧的表面涂布面漆,进行烘干处理,获得包括在油气弹簧外表面依次设置的底漆漆层和面漆漆层;底漆中包含环氧树脂、锌粉、固化剂和溶剂等。采用该工艺在油气弹簧表面形成的漆层结合力良好、不易脱落、服役效果较好,能够起到较好的防护作用。本申请还提供一种油气弹簧、汽车悬架结构及应用,由于油气弹簧具有更长的服役时间和更稳定的工况,更有利于提高汽车悬架结构的运行稳定性和应用。
