Problems solved by technology

[0004] The object of the present invention is to provide an anti-ultraviolet and anti-tarnish industrial gear oil, to solve the above-mentioned background technology. The function needs to be used through other additives or materials, which limits the scope of application of the product and does not have the effect of anti-ultraviolet rays. When the ultraviolet rays are strong in summer, it may cause damage to the structure of the gear. , affect its normal use, and at the same time, under long-term use, the gear may change color, which is inconvenient for maintenance personnel to identify its working status, and it needs to be disassembled to be able to identify it, which increases the difficulty of work , also prolongs the maintenance time, reduces the working speed, and after the additional additives are added to the industrial gear oil, due to the mutual contact of different components, the smell is unpleasant during use, which is not conducive to health and environmental protection problems

Abstract

The invention discloses anti-ultraviolet and anti-tarnish industrial gear oil. The gear oil is prepared from, by weight, base oil, bright stock, an antioxidant, nano silicon dioxide, a UV531 anti-ultraviolet agent, talcum powder, a gear oil additive, a pour point depressant, a defoaming agent and a cosolvent. The anti-ultraviolet and anti-tarnish industrial gear oil solves the problems that industrial gear oil in the existing market does not have an anti-ultraviolet effect, normal use of the industrial gear oil is affected, meanwhile, gears may discolor after being used for a long time, maintenance personnel cannot conveniently distinguish the working state of the gears, and unpleasant smell and unfavorable health and environmental protection exist in the use process of the industrial gear oil due to addition of additional additives in the industrial gear oil, carries out better processing and production work, improves the ultraviolet resistance and tarnish resistance of the product, and can also efficiently resist aging and absorb ultraviolet light.

Description

technical field [0001] The invention relates to the technical field of industrial gear oil, in particular to an anti-ultraviolet and anti-discoloration industrial gear oil. Background technique [0002] Industrial gear oil is used to lubricate positive, helical, herringbone, bevel gears and worm gears. It is divided into closed gear oil, open gear oil and worm gear oil. Among them, closed gear oil is used for gear lubrication with light load. Extreme pressure gear oil contains a lot of extreme pressure antiwear agents, used for medium, heavy load or impact load gear lubrication, mostly used in the metallurgical industry, generally follow the specifications of the American Gear Manufacturers Association and the United States Steel Corporation, open gears The oil has high viscosity and strong adhesion. It is prepared with heavy lubricating oil plus asphalt or polymer adhesive. For the convenience of use, diluent can be added. Refined petroleum lubricating oil or synthetic oil ...
