Abstract
The invention relates to a pre-treatment method for electroplating plastic. The surface of a workpiece is wiped through isopropyl alcohol, and the workpiece wiped through the isopropyl alcohol is put into a cavity of a plasma generator and then is subjected to plasma treatment; then, the workpiece subjected to the plasma treatment is taken out and then is washed with water. The pre-treatment method has remarkable plastic cleaning, activating and roughening effects and is carried out at a room temperature; materials are not deformed so that influences on performances of materials are avoided. Meanwhile, the pre-treatment method is high in safety and adopted main equipment adopts a human-computer interface and visualized operation; a treatment flow can be controlled at any time, the treatment time is short and the treatment efficiency is high; the pre-treatment method is applicable to plastic electroplating of almost materials including ABS (Acrylonitrile Butadiene Styrene), PA (Polyamide), PP (Polypropylene) and the like, electroplating bath liquid is not needed and expensive environment-friendly equipment is also not needed, so that the cost can be remarkably reduced and the environment pollution is avoided.
Description
Technical field
The invention belongs to plastic electroplating technical field, it is related to a kind of pre-treating method for plastic electroplating.
Background technology
Need to carry out pre-treatment before plastic electroplating, traditional pre-treating method frequently with wet processing, that is, passes through oil removing, thick
The operations such as change, neutralisation treatment, multiple washing complete the pre-treatment of plastic electroplating, however, the technological process of traditional pre-treating method
Many, complex operation, and can only several specific plastics such as effective process abs, pc/abs, be of limited application；Electroplate liquid simultaneously
High cost, easily pollutes environment, the chromic acid system that particularly coarsening process adopts.With patent of invention, " a kind of plastic surface plating is micro-
As a example the method for crackle nickel " (application publication number: cn102943292a), must be in sodium hydroxide, sodium carbonate and silicon using the method
Oil removing in sour sodium mixed solution, and be roughened in chromic anhydride and sulfuric acid solution, and must be neutralized with hydrochloric acid, the mist of chromic acid being consequently formed
Post processing must be carried out with plating solution；Therefore, the use of the method also can cause not allowing to neglect to environment while improving production cost
Depending on pollution.
Content of the invention
Present invention aims to above-mentioned deficiency of the prior art, provide a kind of pre-treatment for plastic electroplating
Method, by carrying out plasma treatment to surface of the work, efficiently completes the pretreatment procedure of plastic electroplating.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of pre-treating method for plastic electroplating is it is characterised in that comprise the steps:
1) use isopropyl alcohol surface of the work；
2) it is positioned over above-mentioned in the cavity of plasma generator through the workpiece that isopropyl alcohol is crossed；
3) start air exhauster, be above-mentioned cavity evacuation, make the vacuum in cavity reach 20pa～100pa；
4) after the vacuum in cavity reaches setting value, into cavity, it is passed through h2、n2、cf4Mixed gas, described mixing
The flow of gas is 100～200sccm；
5) power parameter of plasma generator, high frequency electric source 40khz, radio-frequency power supply 13.56mhz are set；
6) power-on, carries out plasma treatment to surface of the work, and the setting processing time is 10s～30min；
7) workpiece through aforementioned plasma treatment is taken out, and be hung on Electropolating hangers；
8) wash, complete the pre-treatment of plastic electroplating.
The beneficial effects of the present invention is:
1st, the present invention is obvious for the cleaning of plastics, activation and roughening effect；First, the present invention can effectively remove plastic table
The organic pollution in face and oxide；Secondly, the present invention can form the groups such as carbonyl, carboxyl, hydroxyl in frosting, and activation is made
With obvious；Further, since plasma can occur materialization effect with frosting, the present invention effectively can be roughened material surface,
And can achieve precise control.
2nd, the present invention is carried out at normal temperatures, and material will not be made to deform, and then avoids the performance on material to produce impact.
3rd, the present invention's is safe, and involved capital equipment adopts man machine interface, visualized operation, can control process at any time
Flow process；
4th, the process time of the present invention is short, efficiency high；The process time of pp material only needs 10s, and conventional wet technique one
As need 15min.
5th, the present invention is applied to the plastic electroplating of the major part material such as abs, pa, pp, without bath solution, more need not be equipped with
Expensive environmental protection equipment, and then, can obviously reduce cost, avoid environmental pollution.
Specific embodiment
The following detailed description of the preferred embodiments of the present invention.
The invention discloses a kind of pre-treating method for plastic electroplating, it specifically includes following steps:
1) use isopropyl alcohol surface of the work；
2) it is positioned over above-mentioned in the cavity of plasma generator through the workpiece that isopropyl alcohol is crossed；
3) start air exhauster, be above-mentioned cavity evacuation, make the vacuum in cavity reach 20pa～100pa；
4) after the vacuum in cavity reaches setting value, into cavity, it is passed through h2、n2、cf4Mixed gas, described mixing
The flow of gas is 100～200sccm；
5) power parameter of plasma generator, high frequency electric source 40khz, radio-frequency power supply 13.56mhz are set；
6) power-on, carries out plasma treatment to surface of the work, and the setting processing time is 10s～30min；
7) workpiece through aforementioned plasma treatment is taken out, and be hung on Electropolating hangers；
8) wash, complete the pre-treatment of plastic electroplating
Plasma processing techniques are applied to the pre-treatment of plastic electroplating by the present invention first, and have been achieved for super expected
Effect, has higher popularizing value.Plasma is the 4th state of material, and the principle of the present invention is: in electric field
Under effect, the gas ionizations such as oxygen, argon are become plasma, then frosting is bombarded, so that frosting is formed
