Thin-layer high-permeability rust-preventive oil

Abstract

The invention discloses thin-layer high-permeability rust-preventive oil consisting of the following raw materials in parts by weight: 70-80 parts of 500sn base oil, 0.5-1 part of sodium hypophosphite, 0.6-2 parts of linalool, 0.1-0.2 part of alkylated diphenylamine, 2-4 parts of polyglycol, 0.6-2 parts of ethylene diamine tetraacetic acid, 1-2 parts of diethyl hydroxylamine, 2-4 parts of dibutyl adipate, 0.1-2 parts of rosin-polythylene oxide ester, 4-7 parts of calcium petroleum sulfonate, 1-2 parts of alkenyl succinic acid ester, 0.1-0.5 part of star anise oil and 15-20 parts of rare-earth corrosion inhibition hydraulic oil. The rare-earth corrosion inhibition hydraulic oil is added into the thin-layer high-permeability rust-preventive oil; polyepoxysuccinic acid and phosphate are mixed together to achieve a very good synergistic effect, so that the thin-layer high-permeability rust-preventive oil has a stable corrosion inhibition function; silicon aluminum sol can promote the compatibility among the materials so as to improve the film forming effect of a finished product; and rare-earth ions added in the thin-layer high-permeability rust-preventive oil can react with OH- generated during oxygen inhalation corrosion on the surface of the metal base material to generate an insoluble complex to slow down electrode reaction of corrosion so as to achieve a very good corrosion inhibition effect.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods for protective coatings from rust damage caused by water or other substances such as saltwater. It involves adding an organopolymer called polyglycidyl azetidone (PGA) into both the coating solution and the steel object being protected. PGAs help prevent oxide formation that forms over time due to dissolved solids entering through cracks made at this interface between them. Additionally, they act like tiny particles when exposed to air, create small holes within it, allowing moisture vapor molecules to pass freely without getting trapped inside. These technical improvements make these materials more effective against rusts compared to previous techniques alone.

Problems solved by technology

This patented technical problem addressed during this patents text relates to preventing metal from being damaged when stored at high temperatures (such as those found inside cars) because they can absorb some amount of water that causes them to lose their shape overtime. Additionally, these solutions may also affect other materials used within an auto body like wires, brackets, bearings, etc., causing issues related to maintain functionality and safety on vehicle components.
