Description

一种低倾点齿轮油及其制备方法
技术领域
本发明涉及润滑油技术领域，具体涉及的是一种低倾点齿轮油及其制备方法。
背景技术
齿轮油以石油润滑油基础油或合成润滑油为主，加入极压抗磨剂和油性剂调制而成的一种重要的润滑油，齿轮油应具有良好的抗磨、耐负荷性能和合适的粘度，此外，还应具有良好的热氧化安定性、抗泡性、水分离性能和防锈性能，由于齿轮负荷一般都在490兆帕(MPa)以上，而双曲线齿面负荷更高达2942MPa，齿轮油的用量约占润滑油总量的6%~8%，齿轮油以石油润滑油基础油或合成润滑油为主，加入极压抗磨剂和油性剂调制而成的一种重要的润滑油，用于各种齿轮传动装置，以防止齿面磨损、擦伤、烧结等，延长其使用寿命，提高传递功率效率，而双曲线齿面负荷更高达2942MPa，为防止油膜破裂造成齿面磨损和擦伤，在齿轮油中常加入极压抗磨剂，普遍采用硫- 磷或硫-磷-氮型添加剂。
用对于齿轮组件用到的齿轮油，目前的配方一般都使用矿物油来进行生产，在一些严寒地区，倾点不佳的齿轮油难免会加剧齿轮组磨损严重的状况，且配方一般都加有硫磷添加剂，对发动机轴瓦表面的合金材质有腐蚀作用，同时磷含量过多，也会使三元催化器中毒，这种情况下，按照目前技术制备的齿轮油，不环保，使用有局限。本发明就是针对目前技术难题进行的全面优化，提供一种低倾点齿轮油及其制备方法，改善齿轮油低温流动性，绿色环保。
