Abstract

The invention relates to a solvent-diluted antirust oil for bearings and a preparation method thereof, belonging to the technical field of antirust oil. The solvent-diluted antirust oil for bearings of the present invention is composed of the following components in weight percent: 25% to 35% of base oil, 9% to 14% of antirust agent, 1% to 3% of spar, and 2% to 5% of film forming agent. %, the balance is solvent oil; the base oil is any one of transformer oil and L-AN total loss system oil. The solvent-diluted antirust oil for bearings of the present invention has low viscosity and strong permeability, and can meet the requirements of spray oiling and rapid dip coating for bearings and parts; it has good film-forming effect, high oil film strength, and good moisture and salt spray resistance. , which can meet the anti-rust requirements of bearing manufacturers in coastal areas; has good anti-overlapping properties, and is suitable for the packaging process of stacking bearings and parts; the appearance, smell, and anti-rust performance are better than imported products, and the price is far lower than imported products. It has broad market application prospects.

Description

technical field [0001] The invention relates to a solvent-diluted antirust oil for bearings and a preparation method thereof, belonging to the technical field of antirust oil. Background technique [0002] Solvent-diluted antirust oil has low viscosity and thin oil film. After oiling, the solvent volatilizes to leave a thin and transparent oil film, which can be used for rust prevention of bearings and parts. The requirements of domestic bearing manufacturers for solvent-diluted anti-rust oil are: the anti-rust process of spraying or rapid oiling can be used, and the oil film after oiling is light, thin and non-sticky; when used in anti-rust and packaging workshops, it smells Small, no adverse effects on the health of the operator, no irritation to the skin; good overlapping resistance, no oil spots and mimeographs when stacked on bearings and parts, and does not affect the appearance; good anti-humidity and anti-salt spray performance, can meet the requirements of bearings ...
