复合型油膜轴承润滑油
技术领域
本发明涉及一种复合型油膜轴承润滑油，是一种具有抗氧性、抗乳化性和抗磨性的复合型油膜轴承润滑油，尤其适用于高速板材和高速线材等轧机支撑辊处油膜轴承的润滑，属于石油化工领域。
背景技术
油膜轴承亦称液体摩擦轴承，它是滑动轴承的一种，是各主要零件的加工精度、表面粗糙度以及各种相关参数（包括润滑油及载荷等）的匹配都非常理想的滑动轴承。工作时在轴与轴承的工作区域形成一个完整的压力油膜，使金属脱离接触，形成纯液体摩擦。由于油膜轴承具备承载能力大，使用寿命长抗冲击能力强等特点，被广泛应用于冶金、玻璃、喷漆设备等机械设备，是现代化轧机关键核心部件之一。
油膜轴承多数处于高温、多尘、有冲击负荷并与水直接接触的苛刻工况条件下，因此对油膜轴承油在分水性能、极压抗磨性能提出了苛刻的要求，开发一种性能优越的复合型油膜轴承油尤为必要。
发明内容
本发明的目的是提供一种复合型油膜轴承油，使其在轴承苛刻的条件下抗氧、抗磨、抗乳化、防腐防锈。
本发明的目的是通过以下技术方案实现。
一种油膜轴承油组合物，其特征在于，所述油膜轴承油由以下重量百分比的原料混合制备而成。
至少一种极压抗磨剂，含量为0.05~2.5重%。
至少一种抗氧剂，含量为0.05~2.0重%。
至少一种防锈剂，含量为0.01~1.0重%。
抗乳化剂，含量为0.005~0.01重%。
消泡剂，含量为0.001~0.01重%。
金属减活剂，含量为0.1~1.0重%。
基础油，余量。
进一步地，所述的组合物中组分(A)为多烷基苄硫化物，或硫代磷酸酯及其胺盐衍生物，或硫代磷酸三苯酯，或二烷基二硫代磷酸锑，或它们任意组合的混合物。
进一步地，所述的组合物中组分(B)为二烷基硫代氨基甲酸锌，或N-苯基-α-萘胺，或烷基化二苯胺，或噻二唑的衍生物，或它们它们任意组合的混合物。
进一步地，所述的组合物中组分(C)为中性或碱性二壬基萘磺酸钡，或烯基丁二酸及其衍生物，或它们任意组合的混合物。
进一步地，所述的组合物中组分(D)为胺与环氧乙烷缩合物，或油溶性聚醚类高分子化合物，或环氧乙-丙烷嵌段聚醚，或它们任意组合的混合物。
进一步地，所述的组合物中组分(E)为丙烯酸酯与醚共聚物，或甲基硅油。
