Gear oil used in low temperature in winter and preparation process thereof

Abstract

The invention discloses gear oil used in low temperature in winter and a preparation process thereof. The gear oil comprises, by weight parts, 8-12 parts of light lube oil, 7-12 parts of petroleum ether, 4-8 parts of graphene, 4-8 parts of oil, 5-10 parts of butter, 18-22 parts of industrial base oil, 8-13 parts of talc powder, 5-10 parts of butylene oxide, 9-13 parts of polyurethane, 7-11 parts of chlorinated paraffin, 5-10 parts of amino silicone oil, 8-13 parts of amino sodium phosphate, 4-8 parts of potassium hydrogen phosphate, 4-8 parts of sorbitol, 2-6 parts of antioxidant preservativeand 8-12 parts of ethanedithiol. The gear oil used in the low temperature in the winter is capable of sufficiently lubricating the gear meshing portion, can maintain certain activity at the low temperature, has a good lubricating effect and is stable in viscosity and long in service life.

Description

Technical field [0001] The invention relates to the industrial preparation field of lubricating oil, in particular to a gear oil used at low temperature in winter and a preparation process thereof. Background technique [0002] Good gear oils generally have characteristic technical indicators and good effects, such as suitable viscosity and good viscosity-temperature properties. Viscosity is the most basic characteristic of gear oils. The viscosity is large, the lubricating oil film formed is thicker, and the load resistance capacity is relatively high. Large, sufficient compression and wear resistance. Wear resistance is a very important technical indicator of gear oil, and load resistance is also an important indicator. Because gear loads are generally above 400Mpa, and the hyperbolic tooth surface load is as high as 1800Mpa, in order to prevent The damage of the oil film causes the wear and abrasion of the gear surface. Generally, extreme pressure anti-wear agents are added to...

Problems solved by technology

[0003] Most of the existing gear oils are general-purpose oils, which are weak in pertinence and poor in pressure resistance. The oil film is easily damaged at the meshing parts of the gears, causing direct contact with the metal surfaces of the meshing parts of the gears and damaging the metal surfaces. Some gear oils are The special gear oil has a high viscosity and can form a thicker protective film on the meshing parts. However, in the low temperature state in winter, the lubricity is poor, the activity of the lubricating molecules is significantly reduced, and the lubricating effect is deteriorated. The direct impact is the gear operation. Need more power, waste power
