Abstract
The invention discloses a metal rust remover and a preparation method thereof, and aims to provide the rust remover which is capable of removing rusts on the surface of a metal and is simple in preparation method. According to the technical scheme, 1L of metal rust remover contains the following components: 150g to 250g of acid, 120g to 200g of oxalic acid, 100g to 150g of carbonate, 20g to 50g of fatty alcohol-polyoxyethylene ether, 3g to 7g of alkylphenol ethoxylates, 5g to 10g of thiourea, 20g to 40g of ethylene diamine tetraacetic acid, 10g to 20g of urotropin and the balance of water. The preparation method comprises the following steps: 1) weighing the components; 2) putting the components weighed by the step 1) in a flask, adding water to reach 1L and then stirring at a room temperature for 5 to 10 minutes so as to obtain the metal rust remover. The metal rust remover belongs to the technical field of metal cleaning.
Description
Technical field
The present invention relates to a kind of Deruster for metal, specifically, relate to a kind of iron and steel or copper or aluminium or stainless rust remover removed, belong to metal cleaning technical field.
Background technology
Metal is placed under outdoor or open-air condition and gets rusty easily, not only affect visual appearance, also can affect normally carrying out of techniques such as spraying paint, bonding, these iron rust have a strong impact on the operation of subsequent technique and the quality of product, as processed not in time, more can cause scrapping of material, cause unnecessary financial loss.
Therefore, rust cleaning is the necessary operation of pre-treatment link in Surface Treatment Engineering, is also surface-treated first critical point.From technique, rust cleaning does not thoroughly directly have influence on the operation of next operation, and possibility contaminate subsequent production line; From coating quality, rust cleaning thoroughly can not reduce the sticking power of film, also can have influence on other performance of coating.In industrial production, often encounter, such as room temperature blackening rete is inhomogeneous, color is inconsistent, local blackout not Shang, electroless plating plating leakage, bonding force are bad, and the problems such as pin hole all eliminate rust and thoroughly do not have direct relation with pre-treatment.Can say, under normal circumstances, the surface treatment quality problems of 50-70% are because rust cleaning does not thoroughly cause, so workpiece surface rust stain must clean up.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide and a kind ofly can remove at normal temperature the simple rust remover of iron rust, preparation method of metallic surface, the present invention also provides the preparation method of this rust remover.
For this reason, last technical scheme provided by the invention is such: this Deruster for metal, every liter of rust remover contains following component: hydrochloric acid 150-250g, oxalic acid 120-200g, carbonate 100-150g, fatty alcohol-polyoxyethylene ether 20-50g, alkylphenol polyoxyethylene 3-7g, thiocarbamide 5-10g, disodium ethylene diamine tetraacetate 20-40g, urotropine 10-20g, surplus is water.
Further, above-mentioned Deruster for metal, every liter of rust remover contains following component: hydrochloric acid 180-220g, oxalic acid 150-180g, carbonate 120-140g, fatty alcohol-polyoxyethylene ether 30-40g, alkylphenol polyoxyethylene 4-6g, thiocarbamide 6-9g, disodium ethylene diamine tetraacetate 25-35g, urotropine 15-18, surplus is water.
Further, above-mentioned Deruster for metal, described carbonate is sodium carbonate.
Further, above-mentioned Deruster for metal, described hydrochloric acid is the hydrochloric acid of concentration 36%-38%.
In order to prepare this Deruster for metal, a rear technical scheme of the present invention is to provide the preparation method of this Deruster for metal, and the method comprises the steps: successively
1) take each component, every liter of rust remover contains following component: hydrochloric acid 150-250g, oxalic acid 120-200g, carbonate 100-150g, fatty alcohol-polyoxyethylene ether 20-50g, alkylphenol polyoxyethylene 3-7g, thiocarbamide 5-10g, disodium ethylene diamine tetraacetate 20-40g, urotropine 10-20g;
2) by step 1) component that takes puts into flask, adds water to 1L, and then stir at normal temperatures and within 5-10 minute, obtain Deruster for metal.
Compared with prior art, technical scheme tool provided by the invention has the following advantages:
1, technical scheme provided by the invention, the hydrochloric acid containing in this formula has potent derusting action, and oxalic acid obviously reduces acid mist, and the synergy of each component of filling a prescription makes this rust remover have the features such as simple to operate, quick, efficient, environmental protection in when rust cleaning.
2, Deruster for metal preparation method provided by the invention is simple, and raw material is easy to get, and is easy to suitability for industrialized production, economic security.
