PREVENTIVE LUBRICANT AGAINST FREEZING OF WET LOOSE MATERIALS TO METAL SURFACE OF TRANSPORT EQUIPMENT Russian patent published in 2015 - IPC C09K3/22 

FIELD: chemistry.

SUBSTANCE: preventive lubricant contains a low solidifying basic fraction, representing a residual part from the distillation of oligomers, and an adhesion component. The preventive lubricant also contains an anionic surface-active substance alkylbenzenesulphonic acid and the non-ionogenic surface-active substance Diproxamine 157. As the low solidifying basic fraction it contains propylene pentamers, obtained as a residue from the the adhesion An oil product - fractions of once-run low-viscosity black oil is applied as the adhesion component.The lubricant is prepared with the following component ratio, wt %: propylene pentamers - residue from the distillation of oligomers - 59.78-59.80; anionic surface-active substance alkylbenzenesulphonic acid - 0.19-0.21; non-ionogenic surface-active substance Diproxamine 157 - 0.009-0.011; the remaining part - oil product black oil to 100%.

EFFECT: invention makes it possible to reduce fire danger, reduce raw material freezing to surfaces at lower temperatures and reduce processing periods between loadings of the raw material.
