Abstract

The invention discloses a metal organic friction repair agent and a preparation method thereof. The preparation method particularly comprises the following steps: adding isocaprylic acid and dimethyl benzene to a reaction kettle; uniformly stirring, then adding copper hydroxide, trihydroxy molybdenum and cerium hydroxide, continuously stirring, adding octyl butyl diphenylamine, heating to 70-150 DEG C for inert-gas protection reaction; and finally adding polyisobutylene succinimide, carrying out reduced pressure distillation, and recovering a solvent. The metal organic friction repair agent obtained through the preparation method disclosed by the invention has good oil solubility in various oil products, does not contain the elements, such as sulfur, phosphorus and halogen which are harmful to the environment, has good repair effect on abrasion marks, can be widely applied to repairing the abrasive surfaces in the fields of compressors, air cylinders, gears, precision machine tools, aerospace and the like and can prolong the service life of rotating equipment, reduce the equipment cost and achieve the purposes of electricity conservation and oil conservation.

Description

technical field [0001] The invention relates to a metal-organic friction repair agent and a preparation method thereof, belonging to the technical field of petrochemical industry. Background technique [0002] Controlling friction, reducing wear, and improving the friction of lubricating oil have become important measures to save energy and raw materials, prolong the service life of equipment, and shorten maintenance time. Lubricants play a very important role in reducing friction and wear. Adding additives is an important technical means to improve the performance of oil products. [0003] With the continuous development of mechanical equipment in the direction of high power, high thermal load, high pressure, high precision, and long service life, the problems caused by friction and wear have become more prominent. In order to reduce or inhibit friction and wear, realize "zero wear" in the true sense. This requires the friction material to have automatic compensation or se...
