一种微纳米发动机油及其制备方法
摘要：
本发明涉及一种微纳米发动机油及其制备方法，所述微纳米发动机油的组分及质量百分含量为：PAO 40％～70％；己二酸酯5％～30％；多元醇酯1％～5％；发动机油复合剂5％～10％；粘度指数改进剂2％～12％；降凝剂0.2％～0.5％；复配微纳米抗磨剂0.1％～4％。本发明微纳米抗磨剂为微纳米金属颗粒经过离心分离、研磨分散、离心处理等工序处理，最后均匀悬浮于PAO中，制备成微纳米浓缩液，将微纳米浓缩液混入以PAO为基础油的发动机油混合液中，保证了纳米粒子的均匀分散，混合后仅恒温搅拌1h后即可得成品，提高了生产效率。
摘要（英）：

The invention relates to micro-nano engine oil and a preparation method thereof. The micro-nano engine oil is prepared from, by mass, 40%-70% of PAO, 5%-30% of adipate, 1%-5% of polyol ester, 5%-10% of an engine oil complexing agent, 2%-12% of a viscosity index improver, 0.2%-0.5% of a pour point reducer and 0.1%-4% of a compound micro-nano antiwear agent. The micro-nano antiwear agent is micro-nano metal particles, the micro-nano metal particles are treated through the processes of centrifugal separation, grinding dispersion, centrifugal treatment and the like and finally uniformly suspend in PAO to prepare micro-nano concentrated liquid, the micro-nano concentrated liquid is mixed with engine oil mixed liquid taking the PAO as base oil, uniform dispersion of the nano particles is guaranteed, after mixing is conducted, the finished product can be obtained only by conducting constant-temperature stirring for 1 h, and therefore the production efficiency is improved.
