Abstract
A kind of fore treatment method of physic plating that plating metal film in the plastic basal material, it includes the following steps: Sand blast handle step, gushing in the surface of base material by using the 180 # to 240 #'s corundum grits with water to do wet style sand blast handle under the pressure of 0.5to 1MPa, and adds degreaser in the water; cleaning step, using ultrasonic wash the outside of the base material which has done the sand blast handles. Using the fore treatment method of physic plating in the invention, forming the microcosmic rough surface in the surface of the plastic base material by sand blast , replacing the dry style sand blast with wet style sand blast, and adding appropriate amount degreaser in the water, to dislodge the fat in the process of coarsening that sand blast in the surface of the plastic base material; it has the following merits: 1. the amounts used grit is small; 2. the coarsening of the surface of the plastic base material and the degreasing are completed at one time; 3.the harshness of the surface of the plastic base material is less, the film electric resistance value which is formed in the process of plating in the follow-up system is low, the effect of guarding against electromagnetism disturbance is good; 4. the product rates is high.
Description
Technical field
The present invention relates to the physical coating method of a kind of vacuum-evaporation and sputter, particularly relate to a kind of with the pre-treating process of physical coating method at plastic basis material coating surface metallic film.
Background technology
Modern electronic product more and more adopts plastic material to make member; plate the plated film of characteristic and strong adhesion on the plastic basis material surface; can reach purposes such as protection base material, decoration, anti-electromagnetic wave, conduction or antireflection, be wherein a kind of common and important enforcement at plastic basis material coating surface electromagnetic interference (EMI) protective film.
Technology at the plastic component surface coating is of long duration, and generally is divided into chemical plating method and physical coating method.
It is low that chemical plating method has price, processing ease, and the rete tack is advantage preferably, but also has the great shortcoming of environmental pollution.Plated film is progressively replaced by physical coating now.
Vacuum coating technology, be called physical coating or physical vapor deposition (Physical VaporDeposition again, be called for short PVD) technology, be meant under vacuum condition, method with physics, material is vaporized into atom, molecule or makes it be ionized into ion, and, have the technology of the film of some property at material or workpiece surface deposition one deck by gas phase process.These two kinds of physical vacuum coating process of vacuum-evaporation and sputter are two kinds of topmost technologies so far.Compare with traditional electroplating technology, but have pollution-free, low-cost, technology simple, can plate advantages such as the many metal cladding kinds of plastics kind are wide.
But, in the physical coating technology, often after the change of plastic basis material or overlay coating material, cause adhesion of coating film can't reach the level of expection, or in order to satisfy the demand of product innovation, the essential sticking power that promotes plated film, these processing procedure bottlenecks need processing parameter and device synchronization adjustment, just can obtain breakthrough improvement.Thereby there is before the applicant proposition to form the scheme that the tack between rete and the base material is improved on micro-rough surface by sandblast on the plastic basis material surface, but, the dry type sandblast is adopted in sandblasting in the scheme before, cause substrate surface roughness height and sand material easily attached to substrate surface and easily cause the product scratch, these all can influence the effect of anti-electromagnetic interference of rete and the tack between rete and the base material.
The present invention is the improvement to the plated film pre-treating process of engineering plastics base material of the effect that improves film adhesion and anti-electromagnetic interference, particularly for PC, ABS and PC/ABS plastics, the PC full name is polycarbonate (Polycarbonate), the ABS full name is acrylonitrile-butadiene-styrene (Acrylonitrile-butadiene-styrene), and the full name of PC/ABS plastics is polycarbonate/ABS resin polymer blending material.
Summary of the invention
The purpose of this invention is to provide a kind of physical coating method that is used for plastic basis material, thereby improve the pre-treating process of the effect of processing parameter and equipment raising rete tack and anti-electromagnetic interference.
To achieve the above object, technical scheme of the present invention is as follows:
The physical coating pre-treating process of metal lining film comprises the steps: on a kind of plastic basis material
The sandblasting step under 0.5 to 1MPa air pressure, adds that with the emergy of 180# to 240# water is sprayed on substrate surface and carries out wet sand blast and handle, and add grease-removing agent in water;
Cleaning step is with the substrate surface of ultrasonic cleaning sandblasting.
The physical coating pre-treating process of metal lining film on the described plastic basis material, wherein, in the described sandblasting step, the emergy of employing is the white fused alumina sand grains.
The physical coating pre-treating process of metal lining film on the described plastic basis material, wherein, plastic basis material can be PC, ABS or PC/ABS.
Adopt physical coating pre-treating process of the present invention, form a micro-rough surface on the plastic basis material surface by sandblast, replace the dry type sandblast with wet sand blast, and in water, add an amount of grease-removing agent, make and in substrate surface sandblast coarsening process, in the lump plastic basis material surface grease is removed; Have following advantage:
1, grit consuming amount is little;
2, plastic basis material surface coarsening and degreasing are once finished;
3, the plastic basis material surfaceness is less, and the rete resistance value that forms in the plated film step of successive process is lower, and anti-electromagnetic interference effect is better;
4, process rate height.
Description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effect apparent by the specific embodiment of the present invention is described in detail.
Fig. 1 is the profile of plastic basis material plated film finished product of the present invention.
Embodiment
For further understanding feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the present invention is limited.
Adopt physical coating pre-treating process of the present invention, as shown in Figure 1, form a micro-rough surface 11 by wet sand blast, in the plated film step of successive process on plastic basis material 1 surface, make to form mechanical riveted between rete 2 and the base material 1, help strengthening the sticking power between rete 2 and the base material 1; Plastic basis material 1 surfaceness is less, and rete 2 resistance values of formation are lower, and anti-electromagnetic interference effect is better; Comprise the steps:
The sandblasting step, 0.5 to 1MPa than under the subatmospheric, add that with the white fused alumina sand grains of 180# to 240# water is sprayed on substrate surface and carries out wet sand blast and handle, and in water, add grease-removing agent;
Cleaning step with the substrate surface of ultrasonic cleaning sandblasting, is washed the sand grains of substrate surface off.
