Motor lubricating oil

Abstract

The invention discloses motor lubricating oil. The motor lubricating oil is characterized in that the motor lubricating oil is prepared from the following components in parts by weight: 0.01-0.5 part of paraffin, 5-13 parts of methylene dichloride, 3-9 parts of trichloromethane, 11-19 parts of n-pentane, 3-9 parts of polyvinyl alcohol, 5-10 parts of normal heptane, 3-5 parts of boric acid, 1-2 parts of sodium benzoate, 0.05-6.4 parts of polyvinylpyrrolidone, 3-6 parts of 1-butyl-3-methylimidazole hexafluorophosphate, 3-12 parts of n-pentane and 40-80 parts of petroleum ether. The motor lubricating oil has the beneficial effects that the lubricating oil has strong universality and good solubility, the concentration of the blended lubricating oil is uniform, the lubricating oil has no sediment or precipitation when being stored for a long time and has good effect, the lubricating oil has no visible residue after liquid components are volatilized, and the lubricating oil has no destructive effect on insulation, can be coated uniformly, has low friction coefficient and low price.

Description

technical field [0001] The invention relates to a motor lubricating oil. Background technique [0002] In recent years, in order to improve the utilization rate of materials, reduce material consumption, increase the winding speed of coils, and reduce the volume of motor and electrical coils, the electrical and electrical manufacturing industry requires excellent Enameled wire with surface lubricity and wear resistance, and can be wound under high speed, high strength and harsh conditions. In particular, in order to comply with the requirements for improving the efficiency of motors proposed by the trend of energy saving in the 21st century, it is necessary to further improve the lubricating performance and wear resistance of the surface to ensure that the properties of the products after winding into coils meet the design requirements, and at the same time meet the needs of increasing production and Economic benefits and requirements to improve the qualified rate of finish...

AI Technical Summary

Problems solved by technology

It has the disadvantages of being volatile, unpleasant smell, poor solubility, unstable friction coefficient and unable to meet customer requirements, and relatively expensive.

The solubility is not good, especially when the temperature is below 10°C, the prepared wax will precipitate, and it is easy to precipitate and accumulate during coating, which makes it difficult to control the amount of wax coating in the production process of enameled wires, causing friction Unstable coefficient

Wax deposits occur during customer winding, blocking the threading hole, easy to break the wire and scratch the paint film on the surface of the enameled wire, affecting the quality of the coil and the normal production of the factory

Especially the use of gasoline lubricating oil in the winter season will give off an unpleasant odor, which will directly affect the workshop environment and production efficiency
