Description
Technical field
The present invention relates to nameplate technology fields, processing technology and its obtained inscription more particularly to nameplate
Board.
Background technique
There are mainly three types of traditional nameplate processing methods with metal sense: first method is directly enterprising in metalwork
Row processing, obtains metallic data plate；Second method is to process patch on the surface of plastic parts after metalwork is processed into nameplate
Then nameplate is glued into patch slot, pressure maintaining, obtains the plastic parts with metal sense nameplate by slot；The third method is on plastic parts
Carry out the processing of positive and negative two sides, step are as follows: transparent material reverse side spraying colored paint --- reverse side plated film --- reverse side sprays shading
--- --- imitative anodic oxidation paint --- front spray paint --- positive laser carving is sprayed in front to front spraying transparent varnish to paint, by figure
Case shape carving removes positive finishing coat and colored paint, it is made to expose the color of back side coating film.
First two method must process the nameplate that could obtain metal sense, higher cost, and second of side on metalwork
The nameplate of method is easy to fall off, and influences the service life of nameplate.
The processing technology of the third method is complicated, the open defects such as metal-like is bad occurs, and yield is low, and be only limitted to plus
The transparent material of work, application range are relatively narrow.

Specific embodiment
It to facilitate the understanding of the present invention, below will be to invention is more fully described.But the present invention can be to be permitted
Mostly different form is realized, however it is not limited to embodiment described herein.On the contrary, purpose of providing these embodiments is makes
It is more thorough and comprehensive to the understanding of the disclosure.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.
The present invention provides a kind of processing technology of nameplate, can be applied to the nameplate processing of nonmetallic materials such as plastic parts, gold
It is good and easy to process to belong to texture.
The processing technology of the nameplate the following steps are included:
Step 1: a clean substrate being provided, in substrate surface sprayed surface inorganic agent, obtains surface treating agent coating.Table
The main function of surface treatment agent coating is the surfacing for making substrate, avoid surface irregularity and under the influence of one layer of attachment.
Further, the thickness of surface treating agent coating selects 10 μm~18 μm, this thickness is mainly used in by PC
Base made of the mixing material of (Polycarbonate, polycarbonate) material or PC and GF (Glass Fiber, glass fibre)
Material selects thickness according to the surface smoothness of substrate.When being made such as substrate of PC and GF, the surface of substrate has bump, floating fibre
The defects of, when the thickness of surface treating agent coating is less than 10 μm, the defect of substrate can not be made up, and bad rate is higher for production；If base
Material is made of PC material, and surface can be relatively flat, when the thickness of surface treating agent coating is greater than 18 μm, influences to adhere to substrate
Power.
Step 2: by basecoat paint in the surface of surface treating agent coating, forming prime coat.
Prime coat is the transition zone of metal film, is attached to metal film preferably on substrate.Prime coat with a thickness of 20~
28 μm, when prime coat thickness is less than 20 μm, the levelling and richness of priming paint are insufficient, influence the overall appearance effect of nameplate；Work as bottom
When thickness of paint layer is greater than 28 μm, prime coat is easy oil accumulation, will affect the attachment of metal film.
Step 3: metal being plated on to the surface of prime coat, forms metal film.
The thickness of metal film selects 0.01~0.1 μm, when the thickness of metal film is less than 0.01 μm, will lead to the metal of nameplate
Texture is poor, when the thickness of metal film is greater than 0.1 μm, will lead to the poor adhesive force of metal film and follow-up coating.
Metal is plated on the surface of prime coat using the method for vacuum evaporation by metal film, is bored by the tungsten of vacuum evaporation equipment
Charging, inlet amount control are that every tungsten bores 1~3.5cm, can get the metal film of 0.01~0.1 μ m-thick.
Step 4: the colored varnish being sprayed to the surface of metal film, forms clear coat.
Clear coat is the transition zone of imitative anodic oxidation paint layer, so that imitative anodic oxidation paint layer is adhered better to substrate, together
When play a protective role to metal film.Further, bloom finishing coat can be selected in the colored varnish, increase the luminosity of metal-like with it is bright
Degree has brilliant gloss levelability, prominent metal-like.Clear coat with a thickness of 20~30 μm, when thickness is less than 20 μm,
Clear coat is easy blistering when subsequent laser carving, and when thickness is greater than 30 μm, clear coat meeting oil accumulation is bad, so the thickness of clear coat
Effect is best when degree is 20~30 μm.
Step 5: imitative anodic oxidation paint being sprayed to the surface of the clear coat, forms imitative anodic oxidation paint layer.
Imitative anodic oxidation paint layer enhances the metal-like of nameplate, can select the imitative anodic oxidation of corresponding color according to demand
Paint.Imitative anodic oxidation paint layer with a thickness of 5~8 μm, when thickness is less than 5 μm, film forming is insufficient, easy floating and texture；Thickness is big
When 8 μm, it is unfavorable for subsequent engraving, and adhesive force is poor；Film forming and adhesive force are taken into account, the more excellent of anodic oxidation paint layer is imitated
With a thickness of 5~8 μm.
Step 6: cover paint being sprayed to the surface of the clear coat, forms cover paint layer.
Dull finishing coat or finish coat varnish can be selected in cover paint, the light of reconciliation nameplate while protecting imitative anodic oxidation paint layer
Sense.Cover paint layer with a thickness of 12~18 μm, when thickness is lower than 12 μm, wearability is insufficient, and the surface of nameplate is easily wiped and spent；Thickness
When greater than 18 μm, the cure shrinkage of cover paint is larger, influences the adhesive force of imitative anodic oxidation paint layer, is unfavorable for subsequent engraving.
Step 7: carrying out laser engraving, remove the colored paint layer and cover paint layer by the shape engraving of predetermined pattern.Laser
Engraving uses optical fiber machine, device parameter are as follows: power: 80~100% (20W), frequency: 20~45HZ, 2000~4000mm/ of speed
S, when power is lower than 80% (20W), nameplate surface engraving is not clean, there is residual.
In some embodiments, nameplate needs to add some colors, then the processing technology of above-mentioned nameplate is gone back before step 4
Including step 3a: colored paint being sprayed to the surface of metal film, forms colored paint layer.
In some embodiments, nameplate is for electronic terminal products such as mobile phones, to avoid electric signal disturbed or being shielded,
The metal of metal film selects semiconductor alloy, such as indium, germanium, while taking into account metal-like, will not interfere or shield electric signal,
And the chemical resistance of semiconductor alloy is good, is not easy to be corroded.
The processing technology of above-mentioned nameplate, metal film and imitative anodic oxidation paint layer make nameplate have good gold
Belong to texture effect, and the adhesive force between each coating and metal film and substrate is good, be not easy to wipe flower and fall off.Overcome the same of substrate
The problem that processing adhesive force is bad on one side and engraving is bad, tow sides processing that no replacement is required, the same face spraying and plated film, processing
Position is easily controllable, reduces difficulty of processing, and controllability is preferable, improves production yield.
