Description

一种发动机用高粘度润滑油
（一）技术领域
本发明涉及润滑油技术领域，特别涉及一种发动机用高粘度润滑油。
（二）背景技术
润滑油是用在汽车、机械设备上以减少摩擦、保护机械及加工件的液体或半固体润滑剂，主要起润滑、冷却、防锈、清洁、密封和缓冲等作用。尤其发动机在运转时，得不到适当的润滑，就会产生干摩擦。实践证明，干摩擦在短时间内产生的热量足以使金属熔化，造成机件的损坏甚至卡死。因此必须对发动机中的摩擦部位给予良好的润滑。当润滑油形成一层油膜，减少摩擦机件之间的阻力，而油膜的强度和韧性是发挥其润滑作用的关键。但现有的润滑油韧性及强度不够，在恶劣的环境下并不能够使用，有时甚至会造成安全事故。
（三）发明内容
本发明为了弥补现有技术的不足，提供了一种高粘度、高品质的发动机用高粘度润滑油。
本发明是通过如下技术方案实现的：
一种发动机用高粘度润滑油，按重量份计由以下成分制成，润滑油基油180份、硅油15份、二烷基二硫代磷酸锌4份、硬脂酸铝3份、滑石粉与高岭土混合物5份、木质素硫酸钠2份、正戊醇8份、聚异丁烯双丁二酰亚胺3份、二异氰酸酯4份、硼酸三异丙酯4份。
所述润滑油基油为矿物油基油，润滑油基油的粘度系数大于90。
所述滑石粉与高岭土混合物经过预处理：将滑石粉与高岭土混合物，放入180-200℃下煅烧1小时后，在采用9.5%浓度的氢氧化钠浸泡40分钟后，过滤，干燥，自然冷却至室温。
所述预处理后的滑石粉与高岭土混合物需与正戊醇和二异氰酸酯混合后， 在40-50℃下进行研磨50分钟，即可添加到润滑油的制作中。
所述润滑油基油与木质素硫酸钠需要提前混合并加热至40-50℃，持续30分钟。
进一步地，所述硅油经过预处理：将总重量份为6份的低聚乙二醇甲基缩水甘油醚与八甲基环四硅氧烷的混合物与硅油混合，在温度为60℃下，反应4-5小时；所述聚乙二醇甲基缩水甘油醚与八甲基环四硅氧烷按3:2比例混合。
本发明的有益效果是：不仅冷却性好，润滑效果佳，生成油膜的韧性及强度较好，能够适应于大多数的应用场合，极大的降低了事故发生的概率，本发明通过添加经过研磨的正戊醇和二异氰酸酯与预处理后的滑石粉与高岭土混合物混合物，极大的提高了润滑油的抗摩性与抗腐蚀性，本发明润滑油在高温下摩擦系数也不会变化太大，稳定性强，配合对润滑油基油与木质素硫酸钠需要提前混合并加热处理，极大的提高了润滑油使用寿命，降低了润滑油更换周期，节约了成本，通过对硅油的预处理，提高了润滑油的粘度指数和润滑油的品质，抗污染能力强。
（四）具体实施方式
一种发动机用高粘度润滑油，按重量份计由以下成分制成，润滑油基油180份、硅油15份、二烷基二硫代磷酸锌4份、硬脂酸铝3份、滑石粉与高岭土混合物5份、木质素硫酸钠2份、正戊醇8份、聚异丁烯双丁二酰亚胺3份、二异氰酸酯4份、硼酸三异丙酯4份。
进一步地，所述润滑油基油为矿物油基油，润滑油基油的粘度系数大于90。
进一步地，所述滑石粉与高岭土混合物经过预处理：将滑石粉与高岭土混合物，放入180-200℃下煅烧1小时后，在采用9.5%浓度的氢氧化钠浸泡40分钟后，过滤，干燥，自然冷却至室温。
进一步地，预处理后的滑石粉与高岭土混合物需与正戊醇和二异氰酸酯混合后，在40-50℃下进行研磨50分钟，即可添加到润滑油的制作中。
进一步地，润滑油基油与木质素硫酸钠需要提前混合并加热至40-50℃，持续30分钟。
进一步地，所述硅油经过预处理：将总重量份为6份的低聚乙二醇甲基缩水甘油醚与八甲基环四硅氧烷的混合物与硅油混合，在温度为60℃下，反应4-5小时；所述聚乙二醇甲基缩水甘油醚与八甲基环四硅氧烷按3:2比例混合。
本发明抗氧抗腐润滑油的性能指标为：
指标，单位
40℃运动粘度，mm²/s 84±1.5
100℃运动粘度，mm²/s 22±1
粘度指数 ≥200
-20℃低温启动粘度，mm²/s ≤3000
倾点，℃ -26
清洁度，级 ≤8
表1
由表1可以看出，本发明抗氧抗腐润滑油性能优越，使用范围广。
将基础油与本发明润滑油在四球机上测定抗磨性与承载能力，在相同实验条件下进行（实验条件为：载荷3500N，实验时间30min，转速1500R/min）：
PB/N PD/N WSD/mm
基础油 391 585 0.73
本发明润滑油 932 659 0.27
注：PB为承载力，PD为烧结负荷，WSD为磨斑直径
表2
由表2可以看出，本发明润滑油明显提高了承载力与烧结负荷，降低了磨斑直径。
