Abstract

The present invention relates to a kind of rust remover improving metal corrosion-resisting, it is characterised in that the most composed of the following components: hydrochloric acid 45 60 parts, phosphatase 24 5 parts, hexamethylenetetramine 0.4 0.6 parts, sodium lauryl sulphate 0.4 0.6 parts, triethanolamine 0.15 0.4 parts, citric acid 0.4 0.6 parts, oleic acid 0.5 1.2 parts, oxalic acid 0.8 1.6 parts, 0.4 0.6 parts of zinc sulfate, 0.1 0.5 parts of aluminum sulfate, stannous sulfate 0.2 0.4 parts, 20 70 parts of water.The present invention adds the solid materials such as zinc sulfate so that after rust cleaning, the corrosion-resistant period ratio virgin metal of metal improves at least one times, can the most quickly derust, not fire the most quick-fried, non-volatile, and light to ground corrosion, price is low, easy to use.

Description

A kind of rust remover improving metal corrosion-resisting

Technical field

The present invention relates to a kind of rust remover, a kind of rust remover improving metal corrosion-resisting.

Background technology

Along with steel and iron industry and the manufacturing development of iron and steel, the corrosion problem of steel becomes increasingly conspicuous, the whole world every year due to The weight of corrosion and the metal material scrapped and equipment is about the 20%-30% of metal annual production, and up to 1 × 10⁸More than t.Right Before metallic article takes various anti-corrosion measure, rust cleaning is necessary processing step.Current derusting method predominantly organic tool method, change The big class of method two.Mechanical Method is that shortcoming is that labor intensity is big, efficiency is low, dust pollution by manually striking shovel, polishing and blasting treatment Seriously, and being limited by Components Shape, the rust of limit, corner angle, re-entrant angle and capillary inside diameter is difficult to clean off totally.Chemical method has effect The best, the series of advantages such as efficiency is high, and technological operation is simple, low cost, are the developing direction of current rust remover.But chemical method is also There is the danger of " hydrogen embrittlement ", contaminated air, after rust cleaning, workpiece need to be cleaned multiple times, and integrated treatment to be made the most also can Get rusty, have a strong impact on the adhesive force of follow-up coating, especially prominent to skin of paint.Derusting method uses impregnated mostly, uses this The method of kind, first needs to build huge immersion trough, and construction investment is very big, also has the most more seriously giving up after changing tank liquor Liquid processes.Therefore, current chemical method is difficult to requiring higher sector application, especially the shipbuilding etc. to outsize workpiece rust cleaning Industry.So needing a kind of rust remover of metal corrosion-resisting that improves badly to solve the problems referred to above.

Summary of the invention

Not enough for above-mentioned prior art, the present invention provides a kind of rust remover improving metal corrosion-resisting.

A kind of rust remover improving metal corrosion-resisting that the present invention provides is achieved through the following technical solutions:

A kind of rust remover improving metal corrosion-resisting, it is characterised in that the most composed of the following components: hydrochloric acid 45- 60 parts, phosphatase 24-5 parts, hexamethylenetetramine 0.4-0.6 part, sodium lauryl sulphate 0.4-0.6 part, triethanolamine 0.15-0.4 Part, citric acid 0.4-0.6 part, oleic acid 0.5-1.2 part, oxalic acid 0.8-1.6 part, zinc sulfate 0.4-0.6 part, aluminum sulfate 0.1-0.5 Part, stannous sulfate 0.2-0.4 part, water 20-70 part.

The invention has the beneficial effects as follows: add the solid materials such as zinc sulfate so that the corrosion-resistant period ratio of metal after rust cleaning Virgin metal improves at least one times；Use the hydrochloric acid of high concentration, the speed that eliminates rust can be accelerated, improve production efficiency, on the other hand, rust cleaning Speed speeds the corrosion that the most relatively slow down workpiece, the addition of phosphoric acid can the effectively bivalence in complex solution and ferric ion, Extend the service life of solution；Restrainer plays synergism by compounding to itself and hexamethylenetetramine；The addition of corrosion inhibiter Neither affect the removing of article surface oxide, can effectively protect again product matrix to be corroded less, reduce hydrogen embrittlement to product Harm；The complexed surfactant chosen can be dissolved in acid solution, contributes to the dispersion of greasy dirt and coming off of rusty scale, also functions to suppression acid The effect of mist；The addition of oleic acid can slow down the corrosion of workpiece；Efficiently quickly derust, do not fire the most quick-fried, non-volatile, ground is corroded Gently, price is low, easy to use.

Detailed description of the invention

By embodiment, technical scheme will be clearly and completely described below, it is clear that described reality Execute a part of embodiment rather than whole embodiments that example is only the present invention.Based on the embodiment in the present invention, this area skill The every other embodiment that art personnel are obtained under not making creative work premise, broadly falls into the model of present invention protection Enclose.

Embodiment 1: a kind of rust remover improving metal corrosion-resisting, the most composed of the following components: hydrochloric acid 45 Part, phosphatase 24 part, hexamethylenetetramine 0.4 part, sodium lauryl sulphate 0.4 part, triethanolamine 0.15 part, citric acid 0.4 part, Oleic acid 0.5 part, oxalic acid 0.8 part, 0.4 part of zinc sulfate, 0.1 part of aluminum sulfate, stannous sulfate 0.2 part, 20 parts of water.

Embodiment 2: a kind of rust remover improving metal corrosion-resisting, the most composed of the following components: hydrochloric acid 52 Part, phosphatase 24 .5 part, hexamethylenetetramine 0.5 part, sodium lauryl sulphate 0.5 part, triethanolamine 0.25 part, citric acid 0.5 Part, oleic acid 0.8 part, oxalic acid 1.2 parts, 0.5 part of zinc sulfate, 0.3 part of aluminum sulfate, stannous sulfate 0.3 part, 45 parts of water.

Embodiment 3: a kind of rust remover improving metal corrosion-resisting, the most composed of the following components: hydrochloric acid 60 Part, phosphoric acid 5 parts, hexamethylenetetramine 0.6 part, sodium lauryl sulphate 0.6 part, triethanolamine 0.4 part, citric acid 0.6 part, oil Acid 1.2 parts, oxalic acid 1.6 parts, 0.6 part of zinc sulfate, 0.5 part of aluminum sulfate, stannous sulfate 0.4 part, 70 parts of water.
