一种挤压防咬合干膜润滑剂及其制备方法
技术领域
本发明属于润滑剂制备技术领域，涉及一种改进的挤压防咬合干膜润滑剂及其制备方法。
背景技术
为满足直升机钛合金中央件、连接件零件承力孔的长寿命要求，必须进行孔强化工艺。在该工艺中，无论采用一次挤压还是二次挤压，如不进行润滑，芯棒和衬套孔壁挤压时会因摩擦力和变形较大而咬死，使挤压无法进行。公开号为CN102199474A的一种金属零部件用干膜润滑剂，由固体润滑剂，耐磨添加剂，分散剂，抗氧化剂，磁性添加剂及粘结基体组成，可应用于各种机械金属零部件的永久润滑，耐磨性较好，其缺点是：第一、在快速挤压时的极压润滑性能较差，不能满足孔强化工艺的要求；第二、不能常温快速固化，固化后也不能采用常规溶剂去除，不方便现场使用。
发明内容
本发明的目的是：提出一种改进的挤压防咬合干膜润滑剂及其制备方法，以便提高极压润滑性能，满足孔强化工艺的要求；同时，实现常温快速固化，并能采用常规溶剂去除，方便现场使用。
本发明的技术方案是：一种挤压防咬合干膜润滑剂，其特征在于：所述干膜润滑剂的组分及质量份数比为：溶剂：100份；二硫化钼：40份～60份；成膜树脂：10份～20份；偶联剂：1份～2份；极压添加剂：2份～10份；所述二硫化钼为颗粒直径≤5μm的微粉；所述成膜树脂为聚酰胺树脂或聚酰亚胺树脂；所述偶联剂为钛酸酯类偶联剂或硅烷偶联剂；所述极压添加剂为氯化石蜡、磷酸酯或硼酸盐中的一种物质或几种物质的混合物；所述溶剂为丁酮、二甲基甲酰胺、正丁醇或二甲苯中的一种物质或几种物质的混合物。
如上面所述的挤压防咬合干膜润滑剂的制备方法，其特征在于：制备的步骤如下：
1、备料：按干膜润滑剂的组分及质量份数比称取原料；
2、制备预混液：将二硫化钼、偶联剂加入溶剂中，加热至70℃～90℃，搅拌0.5h～1h；
3、添加树脂：向预混液中加入成膜树脂，继续搅拌0.5h～1h；
4、添加极压添加剂：向预混液中加入极压添加剂，加热至70℃～90℃，搅拌0.5h～1h后停止加热搅拌，冷至室温后即可。
本发明的优点是：提出了一种改进的挤压防咬合干膜润滑剂及其制备方法，提高了极压润滑性能，满足了孔强化工艺的要求；同时，实现了常温快速固化，并能采用常规溶剂例如汽油、乙醇去除，方便了现场使用。
具体实施方式
下面对本发明做进一步详细说明。一种挤压防咬合干膜润滑剂，其特征在于：所述干膜润滑剂的组分及质量份数比为：溶剂：100份；二硫化钼：40份～60份；成膜树脂：10份～20份；偶联剂：1份～2份；极压添加剂：2份～10份；所述二硫化钼为颗粒直径≤5μm的微粉；所述成膜树脂为聚酰胺树脂或聚酰亚胺树脂；所述偶联剂为钛酸酯类偶联剂或硅烷偶联剂；所述极压添加剂为氯化石蜡、磷酸酯或硼酸盐中的一种物质或几种物质的混合物；所述溶剂为丁酮、二甲基甲酰胺、正丁醇或二甲苯中的一种物质或几种物质的混合物。
如上面所述的挤压防咬合干膜润滑剂的制备方法，其特征在于：制备的步骤如下：
1、备料：按干膜润滑剂的组分及质量份数比称取原料；
2、制备预混液：将二硫化钼、偶联剂加入溶剂中，加热至70℃～90℃，搅拌0.5h～1h；
3、添加树脂：向预混液中加入成膜树脂，继续搅拌0.5h～1h；
4、添加极压添加剂：向预混液中加入极压添加剂，加热至70℃～90℃，搅拌0.5h～1h后停止加热搅拌，冷至室温后即可。
本发明的工作原理是：干膜润滑剂中的二硫化钼颗粒直径极小，配合极压添加剂使用时，能够提供很好的极压润滑性能，这样在进行快速挤压时润滑膜不会被挤出摩擦表面而导致咬死，满足孔强化工艺的要求；同时，采用的成膜树脂添加量不高，可在常温下快速固化并提供合适的附着力，必要时润滑剂可以去除，方便现场使用。
