Abstract
The invention discloses a metal rust removal solution and its preparation method. Specifically, the metal rust removal solution comprises, by weight: 2-6 parts of oxalic acid, 3-5 parts of sodium dodecyl sulfate, 12-18 parts of phosphoric acid, 20-30 parts of hydrochloric acid, 5-10 parts of sodium chloride, 2-6 parts of sodium silicate, 1-3 parts of polyethylene glycol 2000, 10-15 parts of sodium tripolyphosphate, 8-12 parts of alkyl sodium sulfate, 2-6 parts of fatty alcohol-polyoxyethylene ether, and 30-40 parts of water. Rust removal ability tests prove that the metal rust removal solution disclosed in the invention can clear away metal surface rust completely in a short time, and can prevent re-rusting of the metal surface for a long time, thus improving the effective use rate of the metal.
Description
Technical field
The invention belongs to field of metal surface treatment technology, particularly a kind of metal-derusting liquid and preparation method thereof.
Background technology
At present, method for metallic substance and the rust cleaning of metal products surface degreasing has two kinds substantially, traditional method is artificial rust cleaning, specifically utilize and manually carry out the washing of greasy dirt and eliminate rust by the mode of metallic brush wiper, not only labour intensity is large, also needs a large amount of manpower and materials, simultaneously inefficiency, and the rust dirt that causes of rust cleaning flies upward, environment has been caused to pollution everywhere.Another method is chemical rust removing, mainly to utilize the solution of the chemical substances such as acid and the oxide compound generation chemical reaction of metallic surface, generate solvable or insoluble metal-salt, thereby be dissolved in aqueous solution, reach the purpose of rust cleaning, usually use strong acid and strong base rust cleaning oil removing, the method needs special-purpose place, clean simultaneously trouble, speed is slower, efficiency is low, when cleaning, should be noted that the protection personal security, in cleaning process, can produce acid mist simultaneously, affect environment and personnel health, and the metallic surface after processing both can produce the secondary oxidation corrosion after in atmosphere, staying for some time, therefore, can only play temporary corrosion inhibition.
Summary of the invention
The object of the invention is to provides a kind of metal-derusting liquid and preparation method thereof for above the deficiencies in the prior art.
The present invention is realized by following technique means:
A kind of metal-derusting liquid, in components by weight percent, comprise: oxalic acid 2-6 part, sodium laurylsulfonate 3-5 part, phosphatase 11 2-18 part, hydrochloric acid 20-30 part, sodium-chlor 5-10 part, water glass 2-6 part, Macrogol 2000 1-3 part, tripoly phosphate sodium STPP 10-15 part, sodium alkyl sulfate 8-12 part, fatty alcohol-polyoxyethylene ether 2-6 part, water 30-40 part.
Above-described metal-derusting liquid, preferably in components by weight percent, comprise: oxalic acid 3-5 part, sodium laurylsulfonate 4-5 part, phosphatase 11 5-17 part, hydrochloric acid 24-27 part, sodium-chlor 6-8 part, water glass 3-5 part, Macrogol 2000 2-3 part, tripoly phosphate sodium STPP 11-13 part, sodium alkyl sulfate 10-12 part, fatty alcohol-polyoxyethylene ether 4-6 part, water 36-39 part.
The preparation method of more than one described metal-derusting liquid, step is as follows:
(1) according to weight part, take each component;
(2) water is joined in container, be heated to 50-60 ℃, add other each component under the state stirred, dissolve, continue to stir 15-30 minute to dissolve complete.
The prepared metal-derusting liquid of the present invention can be removed rusty stain fully within the shorter time (9min), make metal smoothening bright, and after rust cleaning, can guarantee at least that metal is used in 22 days and no longer gets rusty continuously, has therefore guaranteed effective service efficiency of metal.
