Definitions
- the present invention provides transparent substrates of polycarbonate or polymethyl methacrylate and a process for their preparation.
- thermoplastic materials when polycarbonate or polymethyl methacrylate substrates are used, they are often provided with thermoplastic materials in certain areas of the surface.
- discs are provided circumferentially with elastomers, thermoplastics or thermoplastic elastomers so that they can be installed in the vehicle.
- Automotive polycarbonate or polymethyl methacrylate substrates are replacing more and more mineral gas substrates to save weight. Since the surfaces of polycarbonate or polymethylmethacrylate substrates are generally not sufficiently scratch-resistant, they are usually provided with a hardcoat coating, for example based on silicones. The Hardcoatbe Anlagenelung or Hardcoatveredelung gives the polycarbonate or polymethylmethacrylate a glass-like surface.
- the disadvantage of such hardcoat coatings is the lack of adhesion to elastomeric, thermoplastic materials or thermoplastic elastomers, for example, the randum Anlagenden Seal be used.
- an elastomer or a thermoplastic elastomer is injected onto the surface of the hardcoat-finished polycarbonate or polymethyl methacrylate substrate, this has virtually no adhesion. Accordingly, it has already been proposed in the prior art to achieve adhesion in the regions to be provided with a thermoplastic or an elastomeric material by partially removing the hardcoat coating. For example, the areas to be provided with an elastomer, thermoplastic or thermoplastic elastomer may be treated by milling or lasing, thereby removing the hardcoat coating. However, these methods are extremely expensive and dirty.
- the object of the present invention is to provide polycarbonate or polymethyl methacrylate substrates, that is to say transparent substrates with an all-over hardcoat coating, which have sufficient / good adhesion in defined areas of the surface for an elastomeric, thermoplastic and / or thermoplastic elastomer coating.
- transparent substrates of polycarbonate or Polymethylmethacrylat with a hardcoat coating on all sides which are characterized in that the outer surface of the hardcoat coating has an all-round functional layer obtained by gas phase fluorination, wherein the surface of the functional layer in the edge region of the substrate partially with an elastomeric, thermoplastic and / or thermoplastic elastomer coating or encapsulation is provided.
- the hardcoat coating has sufficient / good adhesion for further coating / overmolding with an elastomeric, thermoplastic or thermoplastic elastomer, when the hardcoat coating provides an all-round function prior to application of the elastomeric or thermoplastic elastomeric coating / overmolding which has been obtained by gas phase fluorination.
- thermoplastics and / or thermoplastic elastomers have already been known, it has been found according to the invention that the areas of the surface which are not provided with a thermoplastic or elastomeric coating, their physical properties in the use of the polycarbonate or polymethyl methacrylate substrates in just these areas do not change negatively. Thus, it could be determined that, in spite of the gas phase fluorination, no losses in the impact strength or notched impact strength of the substrates could be found in precisely these exposed areas of the hardcoat coatings. Also, the UV resistance and the Transparency in visible light is not negatively affected even after prolonged use. This is all the more surprising because even in exposed areas of the hardcoat coating by the gas phase fluorination reactive groups are introduced.
- Transparency in the sense of the present invention refers to the ability to allow electromagnetic waves to pass more or less completely in the visible light range. This permeability to the electromagnetic spectrum of visible light is present according to the invention in the areas in which the surface of the hardcoat coating is exposed. In the areas in which the hardcoat coating is provided with an elastomer, thermoplastic or a thermoplastic elastomer, the transparency is, if measured as transmittance to 0, while in the other areas of the transmittance approaches the value of 1.
- Transparent substrates for the purposes of the present invention also include tinted substrates and substrates which are also used, for example, for non-visible light (night vision devices) or infrared application in assistance systems.
- polycarbonate or polymethyl methacrylate offer a significant reduction in weight since polycarbonate or polymethyl methacrylate has only half the density of a glass.
- Polycarbonate or polymethylmethacrylate enables new freedom of design compared to glass due to the feasibility of complex geometries.
- Polycarbonate or polymethyl methacrylate is sufficiently thermally stable to a thermal curing of Hardcoat coating at temperatures above 100 ° C, in particular to survive temperatures above 125 ° C.
- Polymethylmethacrylate is less stable in this context. These can be produced for example by injection molding, injection compression molding and thermoforming of plates.
- hardcoat coatings which contain, for example, a silicone.
- corresponding silicones are described by way of example, which can also be used according to the invention as a hardcoat coating.
- the present invention is not limited to the hardcoat coatings described herein.
- the hardcoat coatings can be crosslinked by various methods after all-round application. As far as it is known to cure hardcoat coatings thermally, by irradiation with visible light or by UV radiation.
- the substrate made of polycarbonate or polymethyl methacrylate is introduced into a device for the gas phase fluorination according to the invention, and the substrate provided with the hardcoat coating is treated virtually completely superficially.
- gas phase fluorination for surface modification of nonpolar polymer species such as polyethylene or polypropylene to improve the adhesion of paint films or bonds is basically known from a variety of publications of the prior art.
- the basic principle of the process is that protons in the carbon chain are partially substituted by fluorine atoms upon the action of a fluorine-nitrogen mixture on a polymeric surface. Radical reactions activate the oxygen present in the reaction, thereby introducing hydroxyl, keto or carboxyl groups into the polymer matrix, analogously to the corona process. Both reactions lead to a polarity increase.
- the introduction of new functional groups usually does not solve the problem because the matrix is obscured by the deposited additives and thus can not be modified. Therefore, according to the invention, it is not unexpected that the gas phase fluorination also activates the surface of the hardcoat coatings.
- the area of the surface of the hardcoat coating that is exposed to the atmosphere in everyday use of the substrate when the entire surface of the hardcoat coating is exposed to gas phase fluorination is problematic.
- a selective treatment of the hardcoat coating by the gas phase fluorination only in the areas that should be provided with an elastomeric, thermoplastic or thermoplastic elastomer coating would be too expensive, since a masking of the other transparent areas is practically impossible. If, however, the entire surface of the hardcoat coating is exposed to gas phase fluorination, it would be expected that the surfaces of the hardcoat coating exposed later in use would have worse surface properties due to the activation. However, this would not be accepted by the user of the substrate.
- barrier layers are generated, which prevent migration of components of the substrate.
- the vacuum process produces these layers simultaneously and uniformly on both the inside and outside of the substrate. This effective type of property modification allows the use of lightweight, resource-saving materials.
- the reaction chamber is not completely evacuated for the fluorination process, the remaining atmospheric oxygen is also available for the surface reaction.
- fluorine atoms are also oxygen-containing groups produced and incorporated into the polymer chain of hardcoat coating, which also increase the surface energy subsequently.
- hydroxyl and carboxyl groups are available in addition to the fluorine atoms in the next step applied thermoplastics or thermoplastic elastomers as reactants.
- the use of gas phase fluorination makes it possible to provide a coating of the surface of the hardcoat coating partly with a thermoplastic coating and / or a thermoplastic elastomer coating.
- Particularly preferred materials for the purposes of the present invention are elastomers such as EPDM, thermoplastics such as PVC, or thermoplastic elastomers such as TPU, TPS (TPS-SEBS) or TPV (TPV-EPDM + PP). These materials are already used in the field of motor vehicles to connect the transparent substrate, such as a glazing, directly to the (painted) sheet or a soft top made of fabric. Therefore, it is particularly preferred for the purposes of the present invention that the elastomeric, thermoplastic and / or elastomeric coating encapsulation is present around the edge, so that this substrate can be firmly inserted into the assembly.
- elastomers such as EPDM
- thermoplastics such as PVC
- thermoplastic elastomers such as TPU, TPS (TPS-SEBS) or TPV (TPV-EPDM + PP.
- the substrates according to the invention comprise affyverscheibung, this term is not applicable to a motor vehicle, but also to all other vehicles such as aircraft, ships or trains.
- the substrates comprise a vehicle glazing of a motor vehicle, in particular a windshield, side window, rear window or a sunroof of such a motor vehicle.
- the substrates are used for corresponding glazings.
- the layer structure on the surface of the transparent substrate of polycarbonate or polymethyl methacrylate can be prepared by various methods.
- a particularly preferred embodiment of the present invention therefore consists in a process for producing a transparent substrate of polycarbonate or polymethyl methacrylate, which is characterized in that the substrate is provided in a first step with a hardcoat coating, this cures, in a second step, the outer Surface of the hardcoat coating for forming a functional layer of a gas phase fluorination undergoes and provides in a third step, the surface of the functional layer in the edge region of the substrate partially with a thermoplastic and / or an elastomeric coating or encapsulation.
- the layer described above as functional layer which is obtained by gas phase fluorination, can not normally be detected macroscopically by chemical analysis, since the gas phase fluorination only modifies the existing hardcoat coating and does not build up a separate layer on the surface of the hardcoat coating.
- fluorination leads to a change in the free surface energy (this can still be divided into polar and disperse fraction). This change in surface can be measured. This is often done in practice with test inks. Here, however, only the total surface energy is obtained. However, there are also measuring devices for determining the surface energy, which also output the polar (adhesion) and the disperse fraction. With this investigation, however, one gets only a statement that a change has occurred. Fluorine is therefore virtually undetectable in the sample.
- the atomic composition of the surface can be determined, for example, by electron spectroscopy (ESCA also called XPS) or by energy-dispersive X-ray spectroscopy (EDX).
- ESA electron spectroscopy
- EDX energy-dispersive X-ray spectroscopy
- infrared spectroscopy can also be used. Here typical vibration bands of the fluorine can be detected.
- this method is only suitable for samples which have been treated at very low fluorine concentrations.
- a substrate made of an untreated polycarbonate pane of a motor vehicle was produced by injection molding of a commercially available polycarbonate. This material must have a temperature of preferably endure 125 ° C, to be subsequently provided with a hardcoat.
- a commercially available conventional primer was applied by providing the substrate in a corresponding immersion bath with it.
- other known per se application methods such as spraying or painting. After curing of the primer in the course of, for example, 30 minutes at a maximum temperature of 128 ° C, this was cured, so that subsequently the hardcoat was applied and was also cured under the same conditions.
- the hard-coated disc was then subjected to a standard gas-phase fluorination process, namely oxifluoration. At a fluorine concentration in the course of 2 to 10 minutes, the entire disk was treated with the gas.
- This pressure can be applied for example by means of screen printing and per se known colors.
- the printing ink is not affected by the subsequent refinement with hardcoat.
- other printing methods for example tampon and digital printing, are also possible according to the invention.
- a polycarbonate or polymethyl methacrylate substrate may also have a partial printing of the substrate, which may be located between the surface of the substrate and the hardcoat coating.
