Abstract
The invention discloses a deposited metal stripping agent for stripping metals deposited on the inner surface of a chemical plating tank and a preparation method of the deposited metal stripping agent. The deposited metal stripping agent comprises the following components: 250-300ml/L sulfuric acid (98%), 80-100ml/L hydrogen peroxide, 50-60ml/L alcohol, 2-3g/L urea, 25-30g/L tartaric acid, 20-25ml/L propylene glycol, 0.01-0.02g/L sodium lauryl sulfate and the balance of water. The preparation method comprises: adding running water the volume of which is 1/2 of that of a prepared liquid into a container at normal temperature; slowly adding the concentrated sulfuric acid (98%) while stirring continuously; then sequentially adding hydrogen peroxide, alcohol, urea, tartaric acid, propylene glycol and sodium lauryl sulfate; continuously stirring to dissolve the added substances; adding the balance of running water; and stirring until the mixed solution is homogeneous and transparent. As nitric acid is not contained, the deposited metal stripping agent disclosed by the invention does not generate harmful gas, is environment-friendly and pollution-free; and meanwhile, the cost comparison of each component is relatively low, thus the cost is low.
Description
Technical field
The present invention relates to a kind of metal removing agent, more definitely relate to a kind of being used to and strip the metal refining removing agent that the electroless plating tank internal surface deposits the metal that gets off, also relate to the preparation method of this metal refining removing agent.
Background technology
In chemical nickel phosphorus plating or the nickel tungsten phosphorus technology, the coating bath surface usually produces metal refining, and it not only increases the bath element additive decrementation, and reduces other part quality of coating, even causes the spontaneous decomposition of plating bath, therefore needs often stripping.
Concentrated nitric acid is often adopted in the stripping of coating bath surface deposition metal in the past, exists serious obnoxious flavour to pollute.In order to overcome this problem, publication number is that the patent of CN1948552A proposes, and adds the 2-4g/L hydrogen peroxide in chemical plating fluid, submergence metal refining surface, and the temperature of pressing the plating bath electroless plating heats, and makes plating bath and metal refining effect, reaches the removing purpose.This method can obviously change bath element, reduces other part quality of coating, makes plating bath be difficult to continue on for the purpose of electroless plating, thereby also is uneconomic.
Summary of the invention
The objective of the invention is provides the metal refining removing agent and the preparation method of a kind of economy, environmental protection in order to overcome the deficiency of the said products.
Metal refining removing agent of the present invention, form by following each material:
Advantage of the present invention:
1, the present invention adopts sulfuric acid and hydrogen peroxide as oxygenant, makes sedimentary metal become metal ion, has avoided the use concentrated nitric acid and produces obnoxious flavour, environmental protection.
2, the finished product market value of sulfuric acid of the present invention (98%), hydrogen peroxide, alcohol, urea, tartrate, propylene glycol and sodium lauryl sulphate is lower, thereby the cost of this product is lower.
Embodiment
Embodiment one
Metal refining removing agent of the present invention is made up of following each component:
The preparation method of above-mentioned metal refining removing agent is: under the normal temperature, the tap water that in container, adds institute's part long-pending 1/2, under constantly stirring, slowly add the vitriol oil (98%), add hydrogen peroxide, alcohol, urea, tartrate, propylene glycol and dodecane, basic sodium sulfate then successively, constantly stir and make its dissolving, add the tap water of surplus, be stirred to solution and present homogeneous phase transparent.
The using method of above-mentioned metal refining removing agent is: will strip liquid and be heated to 40-50 ℃, and pour in the coating bath, the surface of submergence metal refining, constantly stir, after whole metal refining strippings, pour out stripping liquid, clean coating bath, coating bath can be used for electroless plating once more.
Application example 1 of the present invention:
Use the 1L beaker, contain the acid chemical plating liquid of sulfur acid nickel, inferior sodium phosphate, sodium acetate, lactic acid, be heated to 90 ℃, put into through pre-treatment, surface-area is about 3d m
2The LY12 aluminum pipe, carry out electroless plating, till solution decomposes.Then chemical plating fluid is poured out, the black deposit that cements is all arranged at the bottom of walls of beaker.
The stripping liquid that adds 1L, sulfur acid (concentration 98% wherein, technical grade) according to 250ml, hydrogen peroxide (concentration 30%, technical grade) 80ml, alcohol (technical grade) 50ml, urea 2g/L, tartrate 30g/L, glycerol (technical grade) 20ml, sodium lauryl sulphate (chemical grade) 0.01g, Yu Weishui.Be heated to 50 ℃, constantly stir, walls of beaker, end black deposit constantly come off, dissolve, and about 15min all strips.Stripping liquid is by the colourless light green that becomes.
Application example 2 of the present invention:
Use the 1L beaker, contain the alkaline chemical nickel-plating tungsten phosphorus solution of sulfur acid nickel, inferior sodium phosphate, sodium wolframate, ammonium sulfate, Trisodium Citrate, be heated to 90 ℃, put into through pre-treatment, the about 3d m of surface-area
2Brazed copper tube carry out electroless plating, till solution decomposes.Then chemical plating fluid is poured out, the black deposit that cements is all arranged at the bottom of walls of beaker.
The stripping liquid that adds 1L, sulfur acid (concentration 98% wherein, technical grade) 300ml, hydrogen peroxide (concentration 30%, technical grade) 100ml, alcohol (technical grade) 60ml, urea 3g/L, tartrate 25g/L, glycerol (technical grade) 25ml, sodium lauryl sulphate (chemical grade) 0.02g, Yu Weishui.Be heated to 40 ℃, constantly stir, walls of beaker, end black deposit constantly come off, dissolve, and about 20min all strips.Stripping liquid is by the colourless light green that becomes.
