Hot-rolled oil composition containing organosilicon antiwear slip-proofing agent

Abstract

The invention discloses a hot-rolled composition with organic silicon anti-friction antilubricant, which comprises the following parts: (I) lubricant basic oil with viscosity at 5-300mm2 / s at 40 deg.c, (II) 0.1-20wt% sulphur extreme pressure agent with one or more material from alkyl polysulfide, sulfur ore oil and sulfur polyol ester, (III) 0.05-15wt% phosphorus antiwear agent with one or more material from phosphate, phosphonate, phosphite ester, acid phosphate ester, phosphite ester amine salt, phosphamide ester, dialkyl dithiophosphate, dimercaptothiodiazole dithiophosphate ester and acid phosphate imidazoline salt, (IV) 0.001-25% organosilicon abrasion resistance antilubricant with silicon chloride, C2-16 aliphatic amine, disperser and non-ionic surface activator.

Description

technical field [0001] The invention relates to a hot rolling oil composition. Background technique [0002] The use of hot-rolling oil is a new technology in the field of modern steel rolling. Early hot-rolling did not use oil but was lubricated with water. Later, hot-rolling oil was directly used to lubricate the rolls. Its ingredients include mineral oil, animal and vegetable oils, and synthetic fatty acids. Lubricating oil, causing great pollution. The lubricity of hot rolling has been greatly developed in the past ten years. At present, many large-scale hot rolling mills use the lubrication technology of water and oil co-spraying instead of pure oil lubrication. During the rolling process, a very small amount of hot rolling oil and A large amount of water (more than 99.5%) is mixed, forced to emulsify, sprayed onto the surface of the work roll, and the emulsion is brought into the deformation zone through the rotation of the roll, which not only effectively cools the r...

[0008] There are also some patents that use full oil-soluble formulations, such as JP8041486 (1996), which introduces the addition of 0.05-20wt% lipophilic carboxylic acid, sulfonic acid and anhydride, partial ester, amide and salt hot-rolled oil to inhibit black scale (iron oxide scale) to reduce roll wear, JP8143881 (1996) uses 30-90wt% high alkali value alkylphenol to improve adhesion, but these additives cannot have high extreme pressure, and the pyrolysis products of phenol are also toxic
