Abstract
A kind of method relates to the cling between the EMI metal film using vacuum plating and the plastic cement bottom material, it includes the following steps, step 1: Provide one plastic cement document has high transparent; Step 2: Clean the surface of the plastic cement document; Step 3: the above tier primary coat, the thickness is controlled in 1-10um, then solidified with UV; Step 4: plating a layer of metal material as the metallic film in the way of splash plating. This invention provides a kind of technology which unites the UV solidification and vacuum splash plate, it is used for vacuum plate metallic film which is guard against the EMI, it can make the EMI metallic film gain the merits such as good adhere, low resistance.
Description
Technical field
The present invention relates to a kind of surface treatment method of plastic cement, relate in particular to the method for a kind of vacuum plating EMI metallic diaphragm and plastic rubber substrate tack.
Background technology
In the prior art, the common practices of vacuum plating EMI metallic diaphragm is direct plated film and material sandblast plated film.Directly plated film is exactly a direct plated film on plastic parts, generally is that the mode with vacuum splashing and plating (sputtering) or water plating forms the layer of metal film on plastic parts, and obscission takes place the tack extreme difference of metallic diaphragm and plastic rubber substrate easily like this.Material sandblast plated film is a plated film after sandblast on the material, and this is to increase tack between coatings and the material by increasing the material surfaceness.But because surfaceness increases, cause the resistance value of coatings to increase, bring constant to use.In order to reach than low resistance, must increase coatings thickness, and the increase of coatings thickness causes the increase of internal stress, from and tack is reduced, get back to the original problem that begins the tack difference so again, formed a vicious cycle.
Above-mentioned prior art produces trouble and inconvenience in use, remains in fact to be improved.
Summary of the invention
The invention provides and a kind ofly solidify and the vacuum splashing and plating technology, be used for vacuum plating EMI suppression metallic film in conjunction with UV.Way of the present invention can obtain that height adheres to, low-resistance sheet metal film,
For achieving the above object, the present invention adopts in the following method:
The method of a kind of vacuum plating EMI metallic diaphragm and plastic rubber substrate tack, wherein: comprise the steps,
Step 1 a: plastic parts with high printing opacity is provided;
Step 2: the surface of cleaning plastic parts;
Step 3: last layer primary coat, gauge control are solidified through UV at 1-10um again;
Step 4: plate the layer of metal material as metallic film with sputtering way.
The method of described vacuum plating EMI metallic diaphragm and plastic rubber substrate tack, wherein: this plastic parts is polycarbonate or polymetylmethacrylate material.
The method of described vacuum plating EMI metallic diaphragm and plastic rubber substrate tack, wherein: the mode that goes up primary coat is spraying.
The method of described vacuum plating EMI metallic diaphragm and plastic rubber substrate tack, wherein: described jet-plating metallization material is a copper.
The method of described vacuum plating EMI metallic diaphragm and plastic rubber substrate tack, wherein: described cleaning way is a ultrasonic cleaning.
Description of drawings
Fig. 1 is for handling the synoptic diagram of plastic cement surface section through method of the present invention.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing:
See also Fig. 1, the treatment process of the three-dimensional pattern effect of a kind of plastic cement surface tool metal-like, it may further comprise the steps:
Step 1: a plastic parts 1 with high printing opacity is provided, and this plastic parts 1 is polycarbonate or polymetylmethacrylate material.
Step 2: ultrasound is carried out on the surface of plastic parts 1 clean.
Ultrasonic wave cleaning principle is the high-frequency oscillation signal that is sent by ultrasonic generator, convert the high frequency mechanical oscillation to by transverter and propagate into medium--in the cleaning solvent, ultrasonic wave in scavenging solution density interphase to previous irradiation, make liquid-flow and produce ten hundreds of micro-bubbles.These bubbles form at the negative pressuren zone of ultrasonic wave longitudinal propagation, growth, and at the zone of positive pressure rapid closing.In the process of this being referred to as " cavitation " effect, the bubble closure can form the instantaneous pressure that surpasses 1000 air pressure, continuously produce instantaneous pressure and resemble that a succession of little " blast " is constantly impacted article surface, the surface of object and the dirt in the slit are peeled off rapidly, thereby reach the purpose that article surface purifies.
It is good that the more conventional cleaning way of ultrasonic cleaning has a degree of cleaning height, and the cleaning efficiency advantages of higher is a kind of very outstanding cleaning way aspect the precision cleaning at present.
Step 3: with spraying (spraying) or dip-coating (dipping) mode last layer primary coat 2, gauge control is solidified through UV at 1-10um again.
Spraying (spraying) process is exactly with coating gun tackiness agent to be sprayed on the splicing face of plastic parts 1.
UV curing is meant and adds light trigger (or photosensitizers) in the resin of special formulation, after absorbing the high-intensity ultraviolet light in ultraviolet ray (UV) uv equipment, produce living radical or radical ion, thereby initiated polymerization, crosslinked and graft reaction (do not wait) resin (UV coating, printing ink, tackiness agent etc.) to be converted into by liquid state solid-state in the several seconds.
Step 4: plate the layer of metal material as metallic film 3 with sputtering way.
Sputter (sputtering) is a kind of technology of physical vaporous deposition, and principle is to utilize glow discharge (glow discharge) with argon gas (Ar) ionic bombardment target (target) surface, and the atom of target is deposited in substrate surface and forms film by ejection.Novel sputtering equipment nearly all uses strong magnets that the electronics curl is moved to quicken target argon gas ionization on every side, causes the bump probability between target and argon gas ion to increase, and improves sputtering rate.The common metal plated film mostly adopts dc sputtering, and nonconducting ceramics material then uses RF to exchange sputter.Jet-plating metallization material of the present invention is a copper
The above; only be one of preferable feasible embodiment of the present invention; can not therefore promptly limit to interest field of the present invention; concerning being familiar with those of ordinary skill in the art; such as use technical scheme of the present invention and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong within the protection domain of claim of the present invention.
