Abstract

The invention discloses an extreme pressure resistant additive for industrial gear oil, which is basically characterized by consisting of base oil, antimony dialkyl-dithiocarbamate, phenothiazine, fatty amine, thiadiazole, polyisobutene, polyalkoxy polyamine, a long-chain amino compound, polyalkyl methacrylate, polydimethylsiloxane and metal magnesium powder, namely, 42 to 45 weight percent of lead naphthenate, 3 to 5 weight percent of diarylamine, 3 to 5 weight percent of ethoxyphenol, 3 to 5 weight percent of thiobenzothiazole, 5 to 6 weight percent of dialkyl dithiophosphate, 3 to 4 weight percent of polyisobutene, 2 to 3 weight percent of polyalkoxy polyalcohol, 2 to 4 weight percent of polyalkyl methacrylate, 4 to 5 weight percent of polyacrylate, 3 to 4 weight percent of metal magnesium powder and the balance of base oil. The preparation method of the additive is simple, economic and practical, and the preparation scheme is scientific. The prepared product is applicable to various kinds of industrial gear oil and can improve the extreme pressure resistance of the gear oil by more than 2 times. Besides the extreme pressure resistance of the gear oil, the additive can improve the effects of the gear oil to make the effects of the gear oil exceed national standards and prolong the service life of the gear oil.

Description

(1) Technical field [0001] The invention relates to a gear oil additive, in particular to a preparation scheme and a preparation method of an industrial gear oil anti-extreme pressure additive. (two) background technology: [0002] Most industrial equipment needs to be driven by gears. Such as: crushers, cranes, mobile equipment, grinders, mixers, gearboxes, speed increasers, reducers, etc. They are combined through various connecting materials and gears. Therefore, the requirements for gears are ever-changing, so there are many types and types of gears, such as: spur gears, helical gears, arc gears, bevel gears, worm gears and so on. Because of the above factors, the gear oil must also be changed. However, the current anti-extreme pressure effect of gear oil is not ideal, some preparation schemes have not been carefully analyzed, and the comprehensive performance is poor. The use of base oil, the use of chemical elements, the timing and temperature control of physical p...
