Environmentally-friendly antirust oil with synergistic effects

Abstract

The invention relates to an environmentally-friendly antirust oil with synergistic effects. The antirust oil comprises, by weight, 0.5-30% of barium-free sulfonate, 0.05-15% of an amine salt, 0.5-20%of a lanolin soap and 30-95% of base oil. The environmentally-friendly antirust oil has the following advantages: an oil-soluble antirust agent free from bismuth, lead and other heavy metals, so the antirust oil is environmentally friendly; and the antirust agent is a composition of the barium-free sulfonate, the amine salt and the lanolin soap, so the salt spray corrosion resistance of the antirust oil is effectively improved.

Description

technical field [0001] The invention relates to the technical field of antirust oil products, in particular to an environment-friendly antirust oil with synergistic effect. Background technique [0002] In the field of metal processing, metal parts are susceptible to corrosion damage and deterioration due to the influence of the working environment and surrounding environment during processing, manufacturing, assembly, storage, transportation, use and maintenance. In order to reduce and avoid losses caused by corrosion, anti-rust oil is one of the most common metal protection methods. At present, most of the anti-rust oils on the market use oil-soluble barium salt as an efficient anti-rust agent, which will decompose in the natural environment to produce toxic water-soluble barium salt, which poses serious hazards to human health and the environment. [0003] Chinese patents CN101724499A and CN104312699A disclose an environment-friendly thixotropic antirust oil composed of ...
