Method for preparing composite metal surface anti-rusting detergent

Abstract

The invention discloses a method for preparing a composite metal surface anti-rusting detergent. The method is characterized by comprising the following steps: putting the following components in percentage by mass into a reactor: 53-57% of ethanol, and 43-47% of phosphoric acid so as to obtain a liquid A; putting the following components in percentage by mass into the reactor: 60-66% of water, 1.0-2.0% of sodium cyclohexanediamine tetraacetic acid, 1.0-2.0% of tetradecyl diethoxy amine oxide, 4-8% of trifluoroacetic acid, 13-17% of bromination-1-heptyl-3-methyl imidazole and 12-15% of tri-isopropanolamine, and stirring and dissolving so as to obtain a liquid B; stirring the liquid A and the liquid B for 50-70 minutes in a volume ratio of 1:1 at a rotation speed of 250rpm, thereby obtaining the composite metal surface anti-rusting detergent. No acid mist is generated from the detergent and a cleaning waste liquid, iron structures are not corroded, and meanwhile, the detergent has corrosion resistance, is capable of preventing secondary rusting and is safe and environmental-friendly.

AI Technical Summary

Benefits of technology

This patented composition produces an effective solution that can remove dirt from metals without causing damage or harm their properties during use. It also provides safety features while being produced at lower costs compared to existing methods like chemical treatment techniques.

Problems solved by technology

This patents discusses different ways that may help protect metals from being damaged over their lifetimes without causing any harm during storage or usage. One way involves applying coatings made up mostly of organisms called rust (a type of bacteria) onto the surfaces where these coats form insoluble layers known collectively referred to herein as “rust”). These deposits gradually deteriorate through exposure to moist environments such as rainwater, resulting in reduced durability of the metal. To address this problem, antirritants like calcium chlorite were developed instead of traditional acquirements involving solvents. Another approach was found to involve chemically treating the metal before adding them into solutions containing nitric acid or sulfur dioxides.
