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 iron and steel water-based antirust.
Background technology
The antirust processing of traditional steel surface, great majority adopt nitrite or chromate aqueous solution.This kind method low price, rust-proof effect is better.But because nitrite and chromic salt have very big harm to human body and environment, just be 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 prescription of Sodium Nitrite, but makes complexity, uses inconvenience.Patent publication No. CA101012563A has proposed relative simple formulation and has replaced Sodium Nitrite, and major ingredient is the C8-C10 carboxylate salt, but consumption is big, and price is expensive; It is the water-based antirust agent of main component that patent publication No. CN1712568A proposes with the tetrazotized zole compound; Patent publication No. CN101368274A proposes with sodium pentahydyoxycaproate and benzotriazole compound, benzotriazole sodium, large usage quantity, and price is more expensive, and the rust-preventive agent cost is higher than Sodium Nitrite rust-preventive agent far away.
Summary of the invention
At above-mentioned deficiency, it is simple to the invention provides a kind of composition, with low cost, and favorable rust preventing effect is made simple environment-friendly type iron and steel water-based antirust and preparation method thereof.
The present invention adopts following technical scheme to realize its purpose: a kind of environment-friendly type iron and steel water-based antirust, and it is characterized in that: its moiety and weight percent are:
Residue is deionized water.
Wherein gluconate is ammonium gluconate or Sunmorl N 60S, preferred Sunmorl N 60S.
Wherein molybdate is ammonium molybdate or Sodium orthomolybdate, preferred Sodium orthomolybdate.
Wherein organic phosphoric acid is Amino Trimethylene Phosphonic Acid or ethylenediamine tetramethylene phosphonic acid, preferred Amino Trimethylene Phosphonic Acid.
Wherein nonionogenic tenside is AE07 or OP-10, preferred OP-10.
The preparation method of water-based antirust of the present invention is: take by weighing a composition according to part by weight, add successively, in the 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, and is cheap, and the present invention simultaneously avoids using nitrite, environmental protection; The preparation technology of this invention is simple, favorable rust preventing effect.
Embodiment
The invention will be further described below in conjunction with embodiment, and following embodiment is illustrative, do not have the qualification type, can not limit protection scope of the present invention with following embodiment.
Embodiment one
A kind of environment-friendly type iron and steel water-based antirust, its moiety and weight percent are:

Each composition of the present invention all derives from commercially available finished product, and is with low cost, and the present invention avoids using nitrite, environmental protection, and the present invention simultaneously prepares simply favorable rust preventing effect.
Below the present invention and traditional water based anti-rusting agent are compared:
Example 1: take by weighing following each component according to weight ratio and make environment-friendly type iron and steel water-based antirust:
All the other are deionized water,
pH9.0。
Example 2: take by weighing following each component according to weight ratio and make environment-friendly type iron and steel water-based antirust:
All the other are deionized water,
pH9.5。
Example 3: take by weighing following each component according to weight ratio and make environment-friendly type iron and steel water-based antirust:
All the other are deionized water,
pH8.5。
Reference examples 4:
Sodium Nitrite 20%
Yellow soda ash 0.6%
All the other are deionized water,
pH9。
After the oil removing of No. 45 carbon steel samples processes, rust cleaning, the washing, immerse respectively in the room temperature rust-preventive agent solution of example 1, example 2, example 3 and reference examples 4, kept 20 minutes, take out the back oven dry.
In order to quicken test for rust preventing ability, the sample of above-mentioned processing is immersed respectively in the 5%NaCl aqueous solution, the result is as follows:
The above results shows: environment-friendly type iron and steel water-based antirust of the present invention is better than the Sodium Nitrite water-based antirust to the rust inhibition of iron and steel.
