Abstract
A method for surface treatment of a transparent polymer part is disclosed, consisting of, in a first step, etching a determined topography of patterns in relief onto the external surface of a metal mould using a femtosecond laser and, in a second step, applying the mould under pressure onto the surface of the part to be treated, in such a way as to reproduce the patterns of the mould, in negative, on the part; said topography of patterns being adapted to the type of polymer, both to optimize the wettability of the surface preventing the formation of condensation on said surface and also so as not to affect the optical properties of the part.
Description
Technical field
The present invention relates to the surface treatment of the transparent part under light being obtained by injection molding process, the present invention is especially
It is related to the headlamp of motor vehicles or the inner surface treatment of the glass of signal lighties or minute surface, steam easily in described inner surface
(condensed water being made up of small water droplet).
Background technology
Steam brings initial transparent and bright surface micro white outward appearance, and so that the visual effect on described surface is deteriorated
The optical characteristics (transparency on especially described surface) simultaneously making described surface are deteriorated.
On the other hand, for the headlamp and light signaling devices of more particularly, to motor vehicles glass surface in the case of, steam can
The photometric property of the light beam on surface through fogging is made to be deteriorated.
Headlamp for the use LED being assemblied on increasing vehicle or signal lighties, condensation more makes us
Uncomfortable.
It is true that humidity penetrates into the inside of headlamp or signal lighties in a different manner.It is considered to material in the cause of humidity
The permeability of material：Humidity passes through plastics to enter the housing of headlamp or signal lighties.However, one of larger source is to pass through
The plastic assembly of headlamp or signal lighties is drawing reconciliation wettability.Several dripping be enough to cause inside headlamp or signal lighties
Larger condensation.
It is condensed into the physical phenomenon often occurring in region cold enough.With halogen headlamp or Xenon headlamp phase
Instead, the heat being generated from the headlamp with LED does not distribute to glass and distributes to headlamp rear portion (housing bottom).Have
The domain of cold-zone of the headlamp of LED is therefore more properly located at headlamp glass position.Therefore any condensation directly affects glass
The transparency of glass.This can cause client's aspect complaint and guarantee under complaint and finally cause automaker's brand image
Reduction.
Nowadays, in order to reduce or eliminate the condensation on described surface, (increase the logical of surface using ventilation or air exchange system
Wind), or using the immersion coating (such as paint or chemical thin layer) having compared with strong hydrophilicity or hydrophobic performance, and or using by foaming
Venthole (the Events that the film that PTFE (politef) makes hasAutomotive Vents), described film
There is the hole bypassing air through.
The major defect of these solutions is its application cost (special process during manufacture) and its raw material or zero
The cost of part, and especially immersion coating is aging：, wear trace in loss in efficiency.
Known transparent surface (the such as motor vehicles making to be made up of polymer especially from file US2012/0156431A1
Lateral glass, windshield or car mirror surface) deformation texture (texturer) so that steam can be resisted in described surface
Appearance.
Deformation texture or surface structure represent engraving process and the surface shape of the material obtaining by the method simultaneously
State.
Surface through deformation texture is generally made up of the pattern (or unevenness) of pattern, the spy of described pattern (or unevenness)
Levy in particular, in that roughness, shape, size (width (or diameter)), depth, orientation, periodically, surface area or density ....
File US2012/0156431A1 discloses using thermal photograph lithographic printing (photolithographie) method, with
In the superficial makings deformation making the resin parts obtaining after by injection molding.
Known rough therefore coarse surface has the wettability increasing with respect to smooth surface or reducing.Such as Folium Nelumbinis
There is almost completely not wet characteristic, that is, (water droplet trends towards forming spheroid and trending towards rolling on Folium Nelumbinis surface super-hydrophobicity
Dynamic：Water does not attach from the teeth outwards).
This observation can be related to extremely coarse surface, and this observation in fact includes thering is multiple ratios (é chelle)
Deformation texture.
Two other research making surface more moistening (more hydrophilic) or less moistening (more hydrophobic) is contemplated that and is used for preventing
Mist is processed.In the first scenario it is therefore intended that promoting the expansion of water droplet, to produce set transparent, translucent moisture film, this
Critically important for visibility (for example, the light beam of headlamp and light signaling devices, the what comes into a driver's of glass).
In the latter case it is therefore intended that guaranteeing to make water droplet easily form droplet and without prejudice to table from the teeth outwards
Face what comes into a driver's and transparency.
In both cases it is desirable to reach larger hydrophobicity and hydrophilic, it is advantageously achieved less than 30 ° or is more than
160 ° of contact angle, therefore referred to as super hydrophilic or super hydrophobic surface.
Also define slip angle (or " roll-off " angle, or English be expressed as " sliding angle "), described cunning
Dynamic angle corresponds to the minimal tilt angle of plane (with respect to the horizontal plane), and from described minimal tilt angle, drop starts on surface
Upper slip.This angle particularly depends on the volume of drop, this is because being characterised by competing between drop resistance to sliding and gravity
Strive.Can be measured by drop tensiometer.
Merlon is because its transparent characteristic and mechanical resistance are commonly used to manufacture vehicle head lamp or signal lighties glass
The material of glass.
The deformation texture method of this material will not make material transparent degree and this two characteristics of intensity be deteriorated.
The headlamp and light signaling devices of motor vehicles include the housing closed in a sealing fashion by clear glass and are arranged in
At least one light source of described enclosure interior, at least one light source described can be emitted through the light beam of described glass.
In the face of the glass surface of light source therefore needs, by deformation texture, to promote wettability for one side, and therefore subtract
The steam of few enclosure interior, on the other hand " promotes " wavelength of light beam to pass through described surface to propagate, and does not make the photometric property of light
It is deteriorated, so that the direction acting on the light beam of headlamp glass is deviateed.
Finally, deformation texture need to be reliable and can be produced on the transparent parts being made up of polymer with industrial manner
Raw.
Engraving process disclosed in file US2012/0156431A1 does not ensure the repeatability with the pattern of industrial ratio,
In addition it is not suitable for industrial treatment.
Restriction (the light beam especially to headlamp or signal lighties outfan that the headlamp and light signaling devices of motor vehicles exist
Luminosity mass satisfaction) do not refer in this document.

Specific embodiment
On these figures, identical numerals represent identical element.
The ratio of accompanying drawing is not followed.
The method according to the invention advantageously relates to make (being especially formed from steel) metal die deformation texture, so that logical
Cross the mould marking that feminine gender is produced on polymer (especially Merlon) part that injection obtains.
The engraving of mould or deformation texture are implemented advantageous by the laser using femtosecond type, and other machinery texture
Mode of texturing can be used, such as sandblasting, machining (milling) ...
Femtosecond laser can produce extremely short (about 100 femtoseconds, that is, about 1 × 10-13Second) pulse.However, this pulse
Duration can obtain high power.
The advantage of femtosecond laser is a lot：
- the industrial mould deformation texture that is made of metal can be made；
- deformation texture can be produced by material removal, and so that the mass property of mould is deteriorated, therefore do not make mould
Fragile；
- generate controlled " many ratios " deformation texture：From micron to nanometer.
Additionally, the deformation texture method of the use femtosecond laser according to the present invention (is surveyed on multiple polymer parts samples
Examination) confirm that the negative deformation texture being carried out produces on to the sample.
In addition check the Merlon of moistening and there is the poly- carbonic acid of steam according to the pattern selecting for deformation texture
The performance difference of ester.
Find out from this checking, methods described includes optimizing surface pattern, that is,：The area of pattern, shape, size are (wide
Degree), depth, density and roughness, or unevenness, described fluctuating pattern projects from the surface being considered.
The ratio of pattern need to be less than the wavelength of the light beam needing guiding through glass surface, so that the transparent attribute of holding surface,
And so that the photometric property of light beam is reduced, do not enable beam diffraction (diffraction makes the direction of light beam change) yet；Important parameter
It is related to dipped headlights or the light beam of distance light lamp type.
The part portion producing plug-in unit pattern or " ripple " is hereinafter represented by " region through deformation texture "；By " not
Region through deformation texture " represents the remainder (the supplementary part in " region through deformation texture ") of part.
The pattern example being obtained by the method according to the invention is illustrated on Fig. 1 to Fig. 3.
The optical microphotograph view in the region by " smooth " of " plug-in unit " and through deformation texture for these different accompanying drawings illustrates
The removable section of the referred to as mould of plug-in unit, described mould is used for the injection of Merlon (PC).
Fig. 4 shows the plate shape polycarbonate parts by obtaining according to the injection of known technology.
As an example, shown plate length is 40mm, and width is 15mm, and thickness is 3mm.The only middle body of 1cm2 is by stricture of vagina
Reason deformation, this is invisible on this figure.
Region through deformation texture has figuratum pattern or unevenness, the main ratio of the pattern of described pattern or unevenness
Example is micron (referring to Fig. 3).
Pattern has the substantially sinusoidal shape of cycle about hundreds of nanometers (usually 600nm).These patterns are also with " ripple
The title of stricture of vagina " (wave) is known.The width of wave is of about hundreds of nanometers (usually 600nm).
For the duplication/repeatability quality of the pattern on " quantization " Merlon, the parameter embodying roughness features is tested
Then amount is compared with this parameter on plug-in unit surface.
Major parameter for measurement is as follows：
- Ra is the arithmetic mean deviation of profile, and Rq is quadratic mean deviation, Ra and Rq gives with regard to uneven surface
The information of the average amplitude of degree.Assume：The value that Merlon copy obtains is got over closer to the value of plug-in unit pattern, the quality of duplication
Good；
- Rsk is asymmetric (or " deflection ") factor of the roughness profile of Merlon copy, described copy itself
Need to have the value contrary with the measured value in the case of plug-in unit, this is because copy needs (in the ideal case) to have mould
Negative profile.
- Rku is compression (or " kurtosis ") factor of copy profile, and described copy need to have the value identical with plug-in unit
Value, using the phenomenon of Material shrinkage in the injection moulding process that can make Merlon profile the expected profile of ratio " more flat ".
Fig. 5 gives the plug-in unit (mould) carrying out being considered on part after mould deformation texture printing and plate (part)
The respective profile of the middle body through deformation texture schematic diagram.
The laser-material interaction process of femtosecond state can generate referred to as ripple or LIPSS, and (induced with laser is periodically
Surface texture) submicron periodical pattern.The example of this form illustrates on Fig. 6.
Laser-material interaction process also can make the ripple with large-size (several microns) ratio occur.Fig. 7 is given
The example of this form in laser effect center.In this example, two roughness ratios are overlapping.
Laser pulse spatially and temporally upper shaping can be made, to change generated configuration of surface.
The moving movement of laser beam also can make extra pattern ratio occur.Fig. 8 gives to be had by imbricate arrangement
The deformation texture example on the surface of three form ratios：This surface is represented by many ratios surface.
The laser-material interaction process of femtosecond state can be used directly for the polymeric material texture of antifog application
Deformation, and or directly make the mould deformation texture to be molded with well many ratios copying surface characteristic.
Steam is made to be formed from the teeth outwards so that thousands of (hundreds of) imperceptible water droplet attaches on said surface：Easy to understand
This phenomenon steam is substantially related to moistened surface.
The deformation texture of the part due to being injection molding, the water contacting with surface (such as form of moisture drops) has more moistening or phase
The characteristic of instead less moistening.
For the example of headlamp or signal lighties, when meteorological condition is caught and there is the condensation of water, have extremely
The situation of the deformation texture of hydrophilic (or even super hydrophilic) promote the expansion of condensing drip, therefore diffraction of light and diffusion to be reduced or
Stop.On the contrary, hydrophobic deformation texture promotes the generation of the globule, the less attached from the teeth outwards and on a surface shape of the described globule
Become droplet/flowing, this is avoided or limits the opacity on surface.
Study or caused not by steam by expansion steam or by discharging steam and reducing or eliminating for this two
Comfortable.
The method according to the invention, when the glass by injection manufacture headlamp or signal lighties, selects the texture of mould
Deformation, described deformation texture can be copied on the inner surface of glass, to guarantee the optimised wettability of described glass, and
Therefore, it is possible to reduce or eliminate the deposition of the water droplet of autocondensation, keep the optical characteristics of headlamp or signal lighties simultaneously.
Treatment in accordance with the present invention method can make glass " a large amount of " deformation texture of headlamp or signal lighties：Once metal
Mould, by deformation texture, can produce the multiple clear glasses being made up of polymer through deformation texture afterwards, and keeps and system
Make the working condition identical working condition of glass itself.
