ANTIWEAR AND ANTIFRICTION ADDITIVE WITH FRICTION MODIFIER, LUBRICATING MATERIAL, AND METHOD OF PREPARING FRICTION MODIFIER Russian patent published in 2002 - IPC

FIELD: lubricants. SUBSTANCE: additive improving tribological properties of lubricating materials of various machines and mechanisms under working conditions contains, wt %: chloroparaffins 92.0-93.0, ashless antioxidants 0.8-1.2, dicarboxylic acid esters 6.0-7.0, and friction modifier 0.002-0.02. Antioxidants are of phenol and amine types with working temperature range 100-400 C and inorganic friction modifier is represented by dispersed organobentonite with particle size prepared by modifying bentonite with surfactant of general formula R_fSO₂A, in which R_f represents fluorocarbon radical of general formula with n=1-3 or general formula XC F , with X = F or Cl and m=3-9, and A represents radical of general formula with Hal = Cl or I or radical Bentonite is modified in aqueous medium, wherein bentonite content is 50.0% and that of surfactant 5.0- 7.0, and then ground. Lubricating material consists of lubricating base, to which 1-8% of above-indicated agent is added. EFFECT: improved tribological properties. 18 cl, 3 dwg, 6 tbl
