Abstract
The invention discloses an environment-friendly rust remover which is characterized by comprising the following components in parts by weight: 5-10 parts of methoxy poly (ethylene glycol) amine ionized piperazine-N, N' -bis (2-hydroxypropanesulfonic acid), 2-5 parts of hydrophilic modified Meso-tetramethyl-Meso-tetra-p-aminophenyl cup [4] pyrrole, 1-3 parts of ribavirin carboxylic acid, 1-3 parts of beta-nicotinamide adenine dinucleotide, 0.3-0.8 part of rare earth metal organic framework, 2-6 parts of organic acid, 40-50 parts of water and 10-15 parts of ethanol. The invention also provides a preparation method of the environment-friendly rust remover. The environment-friendly rust remover disclosed by the invention has the advantages of obvious rust removing effect, no damage or corrosion to a metal substrate and small environmental pollution.
Description
Technical Field
The invention relates to the technical field of rust removers, and particularly relates to an environment-friendly rust remover and a preparation method thereof.
Background
In recent years, with the continuous progress of society and the rapid development of economy, metal materials are more and more widely used in daily life of people, are one of the marks of modern civilization, and play a very important role in the production life of people. The rust spots or rusts with different sizes are generated on the surface of the existing metal product or metal recycled product due to the continuous exposure to the factors causing the rusting, and the rust spots and the rusts not only influence the appearance, cause the surface to be uneven and fall off, but also are not beneficial to subsequent machining and manufacturing. Therefore, it is very important to develop a rust removal technology with good rust removal effect.
The prior art mainly comprises two major types of rust removal methods, namely a mechanical method and a chemical method, wherein the mechanical method comprises manual shoveling and polishing, and has the defects of high labor intensity, low efficiency, serious dust pollution and difficult cleaning of rust scale. The chemical method has the advantages of good effect, high efficiency, simple process operation, low cost and the like; however, the conventional chemical treatment rust remover is acidic, and can cause corrosion to the metal surface and cause new corrosion while cleaning and removing rust, so that when the conventional acidic rust remover is used, a corrosion inhibitor is generally required to be matched for use, the use and the operation are troublesome, the cost is increased, and the discharge of cleaning solution after rust removal can cause environmental pollution.
The Chinese patent with application number 200710029019.9 discloses a multifunctional environment-friendly metal oil and rust removing and preventing liquid which is characterized by comprising the following components of polyoxyethylene alkyl ether, sodium dodecyl sulfate, 1, 3-dibutyl thiourea, hexamethylene tetramine, zinc dihydrogen phosphate, phosphoric acid, butyl sodium naphthalene sulfonate, sodium succinate sulfonate, triethanolamine, sodium bicarbonate, tartaric acid and 1, 3-diethyl thiourea. Weighing the raw materials in proportion, dissolving the solid raw materials into a solution by using water, diluting the liquid raw materials by using water, then respectively putting the raw materials into a reaction kettle, stirring for 15-30 minutes, and filtering by using a 120-mesh gauze to obtain a finished product. The multifunctional rust removing liquid can carry out one-time oil removal, rust removal and other treatments on the metal surface due to the synergistic effect of all the components, and basically has no pollution to the environment, but is only suitable for the metal surface treatment with relatively clean surface and low final surface treatment requirement.
Therefore, the development of the environment-friendly rust remover which has an obvious rust removing effect, does not damage or corrode a metal substrate, has small environmental pollution, meets the market demand, has wide market value and application prospect, and plays a very important role in promoting the development of the rust remover industry.
