Abstract
The invention discloses an environment-friendly steel water-based rust inhibitor and a preparation method thereof. The environment-friendly steel water-based rust inhibitor comprises the following compositions in percentage by weight: 3.0 to 5.0 percent of gluconate, 1.5 to 3.0 percent of triethanolamine, 0.4 to 0.6 percent of molybdate, 0.2 to 0.4 percent of organic phosphoric acid, 1.5 to 2.5 percent of sodium benzoate, 0.1 to 0.2 percent of non-ionic surfactants, and the balance of deionized water. The preparation method comprises the following steps of: weighing the ingredients according to a weight ratio; adding the weighted ingredients into the deionized water at 25 to 60 DEG C in sequence; stirring and dissolving, and mixing uniformly to obtain the transparent rust inhibitor with good stability. The ingredients are all from the commercially available products, and therefore the cost is low. In the method, the use of nitrite is avoided, so that the method is green and environment friendly; meanwhile, the environment-friendly steel water-based rust inhibitor is simple to prepare and has a good antirust effect.
Description
Technical field
The invention belongs to field of metal surface treatment, particularly a kind of environment-friendly type steel water-based rust inhibitor.
Background technology
The antirust processing of traditional steel surface, great majority adopt nitrite or chromate aqueous solution.This kind of method low price, rust-proof effect is better.But because nitrite and chromic salt have very large harm to human body and environment, be just restricted, eliminate.The novel water-based rust-preventive agent that exploitation replaces nitrite and chromic salt, meet antirust and environmental requirement is highly significant.
Patent publication No. CN1530463A has proposed to replace the new formula of Sodium Nitrite, but makes complexity, application inconvenience.Patent publication No. CA101012563A has proposed relatively simple formula and has replaced Sodium Nitrite, and major ingredient is C8-C10 carboxylate salt, but consumption is large, price; Patent publication No. CN1712568A proposes to take the water-based antirust agent that tetrazotized zole compound is main component; Patent publication No. CN101368274A proposes with hexonic acid sodium and benzotriazole compound, benzotriazole sodium, large usage quantity, and price is more expensive, and rust-preventive agent cost is far away higher than Sodium Nitrite rust-preventive agent.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of composition simple, with low cost, favorable rust preventing effect, makes simple environment-friendly type steel water-based rust inhibitor and preparation method thereof.
The present invention adopts following technical scheme to realize its object: a kind of environment-friendly type steel water-based rust inhibitor, is characterized in that: its moiety and weight percent this be:
Residue is deionized water.
Wherein gluconate is ammonium gluconate or Sunmorl N 60S.
Wherein molybdate is ammonium molybdate or Sodium orthomolybdate.
Wherein organic phosphoric acid is Amino Trimethylene Phosphonic Acid or ethylenediamine tetramethylene phosphonic acid.
Wherein nonionogenic tenside is AE07 or OP-10.
The preparation method of water-based antirust of the present invention is: according to part by weight, take a composition, add successively, in 25-60 ℃ of deionized water, stirring and dissolving, mixes.
The beneficial effect that technical scheme provided by the invention can reach is: each composition of the present invention all derives from commercially available finished product, cheap, and the present invention simultaneously avoids using nitrite, environmental protection; The preparation technology of this invention is simple, favorable rust preventing effect.
Embodiment
Below in conjunction with embodiment, the invention will be further described, and following embodiment is illustrative, do not have limit type, can not limit protection scope of the present invention with following embodiment.
Embodiment mono-
An environment-friendly type steel water-based rust inhibitor, its moiety and weight percent this be:
Residue is deionized water.
The preparation method of above-mentioned environment-friendly type steel water-based rust inhibitor is: according to part by weight, take a composition, add successively, in 25-60 ℃ of deionized water, stirring and dissolving, mixes.
Each composition of the present invention all derives from commercially available finished product, with low cost, and the present invention avoids using nitrite, environmental protection, and the present invention is simultaneously prepared simply, favorable rust preventing effect.
Below the present invention and traditional water-based antirust are contrasted:
Example 1: this takes following each component and makes environment-friendly type steel water-based rust inhibitor according to weight:
All the other are deionized water,
pH9.0。
Example 2: take following each component according to weight ratio and make environment-friendly type steel water-based rust inhibitor:
All the other are deionized water,
pH9.5。
Example 3: take following each component according to weight ratio and make environment-friendly type steel water-based rust inhibitor:
All the other are deionized water,
pH8.5。
Reference examples 4:
Sodium Nitrite 20%
Sodium carbonate 0.6%
All the other are deionized water,
pH9。
No. 45 carbon steel samples, after oil removing, rust cleaning, washing, immerse respectively in the room temperature rust-preventive agent solution of example 1, example 2, example 3 and reference examples 4, keep 20 minutes, take out post-drying.
In order to accelerate test for rust preventing ability, the sample of above-mentioned processing is immersed respectively in the 5%NaCl aqueous solution, result is as follows:
The above results shows: environment-friendly type steel water-based rust inhibitor of the present invention is better than Sodium Nitrite water-based antirust to the rust inhibition of iron and steel.
