Steel surface cleaning agent and preparation method and application thereof

Abstract

The invention discloses a steel surface cleaning agent and a preparation method and application thereof. According to the steel surface cleaning agent and the preparation method and application thereof, the steel surface cleaning agent is prepared from, by weight, 10-20 parts of polyvinyl propylene, 5-9 parts of nitroglycerin, 2-4 parts of a polycarboxylic acid water-soluble dispersing agent, 7-11 parts of methylbenzene, 0.5-0.9 part of sodium stearate, 8-10 parts of fatty alcohol-polyoxyethylene ether, 2-8 parts of nanometer titania particles, 15-25 parts of cocamidopropyl betaine and 4-10 parts of dodecyl dimethyl betaine. According to the steel surface cleaning agent and the preparation method and application thereof, steel surface deoiling, derusting, phosphorization and passivation can be carried out synchronously, the treatment time is short, the phosphorization quality is good, the problems of serious pollution, long treatment time and large hurt to the human body existing in steel surface treatment are solved, zero-pollution emissions are achieved, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a steel surface cleaner and its preparation method and application as well as its preparation method and application. Background technique [0002] Steel is the most commonly used material in daily life. Steel products are widely used in daily life. However, steel products often undergo oxidation and corrosion to varying degrees during processing, handling and use, which reduces the service life and wastes metal resources. Therefore, it is necessary to treat the steel surface to increase its anti-oxidation and anti-corrosion capabilities and prolong its service life. Steel corrosion is generally divided into chemical corrosion and electrochemical corrosion. Chemical corrosion: corrosion caused by the direct chemical reaction between the metal surface and the surrounding medium. Electrochemical corrosion: the corrosion of metal materials (alloys or impure metals) in contact wit...

Problems solved by technology

[0003] Phosphating treatment is a common treatment method for steel surfaces, but the treatment process is complicated and the treatment time is long

At present, there are many formulas used in phosphating treatment, but most of them contain harmful ingredients to human body and environment. The evaporation of acid mist and the discharge of sewage will pollute the natural environment, and there is no good solution so far.
