The invention discloses a kind of preparation methods of engine abrasion-proof lubricant oil, and this approach includes the following steps：It weighs by mass percentage：Sulfuration cottonseed oil 5.4 8.6%, amine ethyl imidazol(e) hyamine 0.3 1.2%, tributyl phosphate 0.2 0.7%, N, it is oily based on two salicylidene propane diamine 2.1 3.9% of N ', graphite powder 2.5 3.5%, pentaerythrite 1.1 1.5%, triphenyl phosphate 0.3 0.8%, 2,6 di-tert-butyl p-cresol 0.8 1.7%, Nanometer hydroxide 3.2 4.5%, calcium mahogany sulfonate 0.1 0.8%, polyisobutylene-bis-succinimide 0.2 3%, dialkyl dithiophosphoric acid oxygen molybdenum 0.02 0.05%, methyl benzotriazazole 0.2 0.5%, surplus；Ultrasound 10 30 minutes is warming up to 50 90 degrees Celsius and keeps the temperature 15 hours；It is cooled to room temperature and can be obtained finished product.Every physical and chemical index of energy autobalance lubricating oil of the invention, lubricants performance is set more permanently to keep optimum Working, ensure minimum lubrication oil consumption and real overlength oil draining period (20000kg), balanced nutrition is provided for love vehicle to safeguard, solves the synthtic price index such as carbon deposit is excessive, fuel consumption is big, abrasion is larger. |
