Abstract

The invention discloses a kind of film-cleaning anti-rust oil for an automobile connecting rod, a preparation method therefor and applications. The anti-rust is prepared from 150SN neutral base mineral oil, 200#solvent naphtha, deodorized kerosene, alkaline barium dinonyl naphthalene sulfonate, petroleum barium sulfonate, petroleum sodium sulfonate, synthesized calcium sulfonate with high base number, refined industrial lanolin, emulsifiers, dodecenyl succinic acid, functional composite displacement antirust agents, 2,6-butylated hydroxytoluene and tricresyl phosphate. The anti-rust oil can form a layer of protection coating on a material surface, the coating has strong compactness, good adhesion, is naturally quick-drying and in a half hard film state, and has atmosphere corrosion resistance, excellent moisture resistance and salt mist resistance, and the anti-rust life can reach above one year. The anti-rust effects are good. The anti-rust oil can completely meet anti-rust quality technical requirements of users during processes of production-manufacturing, transportation, storage and the like.

Description

technical field [0001] The invention belongs to the technical field of metal anti-corrosion and surface, and in particular relates to a cleaning thin-film anti-rust oil for automobile connecting rods, a preparation method and application thereof. Background technique [0002] During the process of production, manufacturing, storage and transportation, the connecting rod products of the key parts of internal combustion engine automobile engines need to be treated with oil seal and antirust treatment. They cannot be installed until the automobile engine is unsealed and cleaned to remove mechanical impurities before the final assembly of the automobile engine. [0003] Due to strict production technology, connecting rod assembly products have a long cycle, complex process and many procedures in the process of production, processing, storage and transportation, which brings certain difficulties to anti-rust management and technical application. The factory requires that the oil ...
