Motor lubricating oil and preparation method thereof

Abstract

The invention discloses motor lubricating oil and a preparation method thereof. The motor lubricating oil is prepared from base oil, an anti-oxidant, dinonylnaphthalenesulfonic acid barium salt, trioctyl trimellitate, sodium alkyl naphthalene sulfonate, methyl silicone oil, polyethylene oxide and lithium 12-hydroxystearate, wherein the weight-average molecular weights of polyethylene oxide and sodium alkyl naphthalene sulfonate are 1000-3000 and 2000-4000 respectively. The motor lubricating oil is high in viscosity and kinematic viscosity index, and has a pH value of 6-8; the preparation method of the motor lubricating oil is simple, and raw materials are easy to obtain.

Description

technical field

[0001] The invention relates to lubricating oil, in particular to a lubricating oil for motors and a preparation method thereof. Background technique

[0002] Lubricating oil is an essential chemical substance in the process of motor operation and maintenance. In order to make the lubricating oil have excellent viscosity and kinematic viscosity index, the existing lubricating oil manufacturers often add a series of additives to the lubricating oil, but ignore the lubricating oil. The acidity and alkalinity of the oil makes the lubricating oil corrode the motor while lubricating and protecting the motor, which seriously affects the life of the motor. Contents of the invention

[0003] The purpose of the present invention is to provide a kind of lubricating oil for motor, the lubricating oil has excellent viscosity and kinematic viscosity index, and the pH of the lubricating oil is 6-8, the method for preparing the lubricating oil is simple, and the raw mater...
