Problems solved by technology

[0004] At present, the commercially available special anti-rust oil is sprayed or brushed on the oil film of large marine shafting diesel engine parts, which is difficult to remove after natural draining or has poor anti-corrosion performance. After the surface mechanical finishing treatment of various large-scale shafting products used in ships, due to the stay in the workshop, warehouse or short-term storage, transportation to assembly and use, due to the influence of factors such as industrial environment and humid atmospheric corrosion, the metal surface It is easy to be corroded by the harsh corrosive environment medium of the seaport or adsorbed water vapor to condense to produce electrochemical corrosion, resulting in the need for rework and derusting treatment or even scrapping the product
In addition, the anti-rust oil is not resistant to heat and humidity, and is not suitable for use in coastal marine environments.

Abstract

The invention discloses brown high-build quick-drying antirust oil applicable to diesel engines of ships and warships and a preparation method thereof. The black high-build quick-drying antirust oil applicable to the diesel engines of the ships and warships is prepared from 150SN neutral basic mineral oil, No.120 solvent oil, acetone, tricresyl phosphate, barium petroleum sulfonate, barium soap of petroleum ester oxide, refined lanolin magnesium soap, a multi-effect compound antirust agent, rosin modified phenolic resin, No.56 semi-refined paraffin wax and No.2 industrial Vaseline. The brown high-build quick-drying antirust oil can form a semi-hard membrane-like protective coating with strong compactness, good adhesive force and naturally quick-drying property on the surface of a material, is resistant to atmospheric corrosion and has excellent moisture resistance and salt mist resistance, and the rustproof life can be more than three years; the antirust effect is good, and the antirust quality technical requirement of a user on products in processes of production, manufacturing, transportation, storage and the like can be completely met.

Description

technical field [0001] The invention belongs to the technical field of metal anti-corrosion and surface, and in particular relates to a brown thick paste quick-drying anti-rust oil suitable for marine diesel engines and its preparation method and application. Background technique [0002] In the process of production, manufacturing, storage and transportation of large-scale shafting diesel engine parts of ships, external oil seal anti-rust treatment is required until the parts of large-scale shafting diesel engines of ships are guaranteed to be rust-free, unsealed and cleaned before installation Only then can it be assembled and used. [0003] Due to the high cost of large-scale marine shafting diesel engine parts, high machining accuracy is required in the manufacturing process, especially the product needs to go through multiple links such as manufacturing, processing, storage, and transportation. The cycle is long, and the product weight and volume are large. Loading and...
