Description
Technical field
The present invention relates to frosting process, particularly relate to a kind of ABS plastic face coat and preparation method.
Background technology
The plastics being now widely used for plating have ABS PC+ABS and PA, and the plastics being applied to sanitaryware mainly have ABS to mould
Material, plastic electroplating is exactly to use certain processing method, first obtains conducting film at frosting, then thickeies with electric plating method
Process.Therefore plastic electroplating technique can also be briefly divided into two and walks greatly, and the first step is the pre-treatment of plastic electroplating: oil removing →
Roughening → neutralization → catalysis → dispergation → chemical nickel；Second step is plastic electroplating: nickel preplating → bright copper → semi-bright nickel；3rd
Step is wire drawing → oil removing → passivation → spraying, and the paint of spraying divides according to light transmission mainly two kinds: one is clear transparent paint,
Another kind is dumb light paint.Passivation technology is passivated frequently with Cr VI, can produce substantial amounts of waste water and heavy metal ion in this flow process,
Such as hexavalent chromium can produce harm to environment, the mankind, due to needs electro-coppering, can cause the corrosion resistance of surface-treated layer relatively
Difference, usual solution be the thickness increasing electronickelling to promote corrosion resistance, but production cost can be promoted accordingly, cause nickel resources
Waste.
Chinese patent 201220188606 discloses a kind of ABS plastic surface plating structure with wire-drawing effect, this structure by
Interior to including ABS plastic surface, electroless nickel layer, alkaline copper plating layer, wire drawing electroless nickel layer and electrodeposited chromium layers successively outward.
Zhang Hua (China. Environmental Technology periodical, 2013 04 month) disclose automobile plastic ornament electroplating technology and performance detection thereof,
This article describes the effect of electro-coppering: copper has good ductility, the thermal coefficient of expansion of pliability, relatively other coating in detail
Closer to plastics.The layers of copper that thick layer about 15～25 μm is smooth and pliable and tough, beneficially increase by zero is plated at plastic part surface
Part and the adhesion of whole coating, temp. variation resistant ability and corrosion resistance, when part is by ambient temperature change or impact
A cushioning effect can be played, reduce the part extent of damage.Visible electro-coppering is indispensable in current plastic electroplating operation
Part, the adhesion that its major function is to increase between follow-up electrodeposited coating and plastics and the part stress of reduction nickel dam.
There is problems with in the plating of existing ABS plastic, as needed electro-coppering, due to needs electro-coppering, surface can be caused to process
The corrosion resistance of layer is poor, usual solution be the thickness increasing electronickelling to promote corrosion resistance, but production cost can be promoted accordingly,
Nickel resources is caused to waste.
Summary of the invention
Present invention aims to the problems referred to above present in the plating of existing ABS plastic, it is provided that ABS plastic part electricity can be shortened

0.5 μm, 2) impact nickel dam, thickness is 1～3 μm, 3) half light nickel dam, thickness is 3～8 μm, 4) organic coating, thickness
It is 10～20 μm.
The preparation method of described ABS plastic face coat, comprises the following steps:
1) pre-treatment of ABS plastic: electrochemical deoiling → roughening → neutralization → catalysis → dispergation → plating electroless nickel layer；
2) in electroless nickel layer, carry out impacting nickel plating obtain re-plating half light nickel dam after impact nickel dam；
3) on half light nickel dam, wire drawing process is carried out；
4) the ABS plastic plated item after wire drawing processes carries out hydrocarbon vacuum oil removing and drying and processing；
5) it is coated with organic coating on the ABS plastic plated item after step 4) processes.
In step 1), the pre-treatment of described ABS plastic is carried out according to currently known processing mode.
In step 2) in, described in carry out impacting nickel plating, use known impact nickel formula to electroplate；Described plating half light nickel
Layer, uses known half light nickel formula to electroplate.
In step 3), described wire drawing processes, and automatically or manually wire drawing mode can be used to carry out wire drawing, the rotating speed of wire drawing machine
It is 600～1200r/min；Pulling wheel can be at least one in nylon wheel, all-wing aircraft wheel etc..
In step 4), described hydrocarbon vacuum oil removing and drying and processing, the ABS plastic plated item after wire drawing can being processed is suspended to
Spraying paint and carry out hydrocarbon vacuum oil removing and drying and processing on hanger, the oil removing time is 3～8min, and drying time is 5～10min.
In step 5), described in be coated with organic coating, can by step 4) process after ABS plastic plated item directly hang over spray
It is coated with on hanger and carries out spray treatment, be coated with organic coating；Described organic coating can use ultraviolet light polymerization (UV) paint, polyurethane
(PU) at least one in paint etc.；The method that spraying method is known to those skilled in the art.
Present invention have an advantage that
Simplify existing electronickelling wire drawing to spray paint the technological process of production of product, broken in ABS plastic plating and must use plating
The inherent limitations of copper process.Simultaneously as surface layer does not has layers of copper, therefore can reduce original nickel dam thickness (from
Originally 15～20 μm are down to 3～6 μm), save metals resources, not only shortened process, and production can be greatly lowered
Cost.
