Definitions
- the present invention relates to compositions comprising a thermoplastic and a multilayer pigment, and to a process for
- Polycarbonate sheets are known, for example, from EP-A 0 110 221 and are provided for a large number of applications.
- the production is carried out by extrusion of polycarbonate and optionally coextrusion with molding compositions which contain an increased proportion of UV absorbers.
- EP-A 0 320 632 teaches that the plates are to be equipped with a coextrusion layer which contains low-volatility UV absorbers in increased concentrations.
- EP-A 0 678 376 teaches that for plates made of polyesters, in particular for plates made of copolyesters of aromatic dicarboxylic acids and mixtures of two aliphatic diols such as e.g. Ethylene glycol and cyclohexanedimethanol (PETG), weather protection is achieved by coextrusion with top layers, the UV absorbers e.g. based on benzotriazoles in increased concentrations.
- PETG Ethylene glycol and cyclohexanedimethanol
- German patent DE-C 25 44 245 a board made of polymethyl methacrylate with a content of light-reflecting particles aligned parallel to the surface is known. Their layer thickness is dimensioned such that they largely let visible light through and largely reflect infrared radiation.
- the known body contains the light-reflecting particles in the base material made of polymethyl methacrylate. They are introduced into the liquid methyl methacrylate monomer, this in a polymer formed from glass plates arranged in parallel. sationssch filled and partially polymerized. Up to this point the particles have sunk onto the lower glass plate. By parallel displacement of this plate, the particles are aligned parallel to the surface and held in this position as the polymerization continues. This treatment stage makes the manufacturing process complex and expensive.
- EP-A 340 313 describes solar radiation-resistant coatings for ships, tanks, buildings and the like in order to reduce their heating in the sun.
- the coatings contain a binder, a heat-reflecting pigment and, if necessary, any color pigments.
- polyethylene sheets for greenhouses are provided with a coating by brushing or spraying, which contains light-reflecting pigments in a matrix of a paint binder. Since the pigment particles are not oriented by the application process, they only have a shading effect and result in unsatisfactory transmission. As a result of the low adhesion of conventional paint binders to polyethylene, the coating can easily be washed off the coated web with a water jet.
- EP-A 0 548 822 describes PMMA sheets which are special in the coextrusion layer
- EP-A 0 774 551 describes various types of coextruded polycarbonate sheets which can contain several coextrusion layers. Each individual coextrusion layer gives the plate different functions. For outdoor applications, it is important that the pigment-containing layer is covered with an overlying UV protective layer, since the weather stability of the pigments in polycarbonate is not sufficient. The UV protection layer on top protects the plate from severe yellowing.
- the multilayer coextrusion is cumbersome and expensive, since at least two different coextrusion molding compounds have to be produced and at least 2 coextruders have to be connected to the main extruder.
- the present invention is therefore based on the object, weather-stable
- compositions that allow the production of products with pearlescent surfaces.
- the present invention is based on the object of providing products made from these compositions.
- a multilayer pigment consisting of a carrier material in the core, a first layer of titanium dioxide lying on top, a second layer of silicon dioxide lying on top and a third layer of titanium dioxide lying on top.
- the object of the invention is achieved by products containing the compositions of the invention.

- the multilayer pigment according to the invention can also contain more than 3 coating layers over the carrier material. There can also be others between the above-mentioned coating layers of titanium dioxide, silicon dioxide and titanium dioxide.
- Coating layers lie.
- the layers of the multilayer pigment according to the invention preferably have the following thicknesses:
- the first layer of titanium dioxide which lies over the support material, preferably has a thickness of 100 to 180 nm, in particular 110 to 120 nm.
- the second layer of silicon dioxide above it preferably has a thickness of 100 to 150 nm, in particular 110 to 140 nm.
- the third overlying layer of titanium dioxide preferably has a thickness of 110 to 160 nm, in particular 120 to 150 nm.
- the multilayer pigment according to the invention can also be constructed such that instead of the layers made of titanium dioxide, layers made of other metal oxides with high
- Refractive index can be used.
- these can be, for example: zirconium oxide, iron (III) oxide, iron (II, III) oxide, chromium trioxide or zinc oxide or iron titanium. nates, iron oxide hydrates or titanium suboxides or mixtures or mixed phases of these compounds with one another or with other metal oxides.
- the multilayer pigment according to the invention can also be constructed such that a layer made of another metal oxide with a low refractive index is used instead of the layer made of silicon dioxide.
- a layer made of another metal oxide with a low refractive index is used instead of the layer made of silicon dioxide.
- silicon dioxide this is, for example, aluminum oxide, aluminum oxide hydrate, boron oxide or a mixture thereof.
- the low refractive index oxide layer may also contain alkali oxides and alkaline earth oxides as components.

Die vorliegende Erfindung betrifft Zusammensetzungen enthaltend einen thermo- plastischen Kunststoff und ein mehrschichtiges Pigment sowie ein Verfahren zurThe present invention relates to compositions comprising a thermoplastic and a multilayer pigment, and to a process for
Herstellung von Erzeugnissen, enthaltend diese Zusammensetzungen sowie Erzeugnisse enthaltend diese Zusammensetzungen, insbesondere Platten enthaltend diese Zusammensetzungen.Manufacture of products containing these compositions and products containing these compositions, in particular sheets containing these compositions.
Polycarbonatplatten sind beispielsweise aus EP-A 0 110 221 bekannt und werden für eine Vielzahl von Anwendungszwecken bereitgestellt. Die Herstellung erfolgt durch Extrusion von Polycarbonat und gegebenenfalls Coextrusion mit Formmassen, die einen erhöhten Anteil an UV- Absorbern enthalten.Polycarbonate sheets are known, for example, from EP-A 0 110 221 and are provided for a large number of applications. The production is carried out by extrusion of polycarbonate and optionally coextrusion with molding compositions which contain an increased proportion of UV absorbers.
Für den Langzeitschutz gegen Vergilbung durch UV-Licht lehrt EP-A 0 320 632, dass die Platten mit einer Coextrusionsschicht auszurüsten sind, die schwerflüchtige UV- Absorber in erhöhten Konzentrationen enthalten. EP-A 0 678 376 lehrt, dass für Platten aus Polyestern, insbesondere für Platten aus Copolyestern von aromatischen Dicarbonsäuren und Mischungen zweier aliphatischer Diole wie z.B. Ethylenglykol und Cyclohexandimethanol (PETG), der Witterungsschutz durch eine Coextrusion mit Deckschichten erreicht wird, die UV-Absorber z.B. auf Basis von Benzotriazolen in erhöhten Konzentrationen enthalten.For long-term protection against yellowing by UV light, EP-A 0 320 632 teaches that the plates are to be equipped with a coextrusion layer which contains low-volatility UV absorbers in increased concentrations. EP-A 0 678 376 teaches that for plates made of polyesters, in particular for plates made of copolyesters of aromatic dicarboxylic acids and mixtures of two aliphatic diols such as e.g. Ethylene glycol and cyclohexanedimethanol (PETG), weather protection is achieved by coextrusion with top layers, the UV absorbers e.g. based on benzotriazoles in increased concentrations.
Aus der deutschen Patentschrift DE-C 25 44 245 ist eine Tafel aus Polymethyl- methacrylat mit einem Gehalt an lichtreflektierenden, parallel zur Oberfläche ausgerichteten Teilchen bekannt. Ihre Schichtdicke ist so bemessen, dass sie sichtbares Licht weitgehend durchlassen und infrarote Strahlung weitgehend reflektieren.From the German patent DE-C 25 44 245, a board made of polymethyl methacrylate with a content of light-reflecting particles aligned parallel to the surface is known. Their layer thickness is dimensioned such that they largely let visible light through and largely reflect infrared radiation.
Der bekannte Körper enthält die lichtreflektierenden Teilchen in dem Basismaterial aus Polymethylmethacrylat. Sie werden in das flüssige Methylmethacrylat-Monorner eingebracht, dieses in eine aus parallel angeordneten Glasplatten gebildete Polymeri-
sationskammer eingefüllt und teilweise polymerisiert. Bis zu diesem Zeitpunkt sind die Teilchen auf die untere Glasplatte abgesunken. Durch eine Parallelverschiebung dieser Platte werden die Teilchen parallel zur Oberfläche ausgerichtet und in dieser Stellung bei Fortsetzung der Polymerisation festgehalten. Durch diese Behandlungs- stufe ist das Herstellungsverfahren aufwendig und teuer.The known body contains the light-reflecting particles in the base material made of polymethyl methacrylate. They are introduced into the liquid methyl methacrylate monomer, this in a polymer formed from glass plates arranged in parallel. sationskammer filled and partially polymerized. Up to this point the particles have sunk onto the lower glass plate. By parallel displacement of this plate, the particles are aligned parallel to the surface and held in this position as the polymerization continues. This treatment stage makes the manufacturing process complex and expensive.
EP-A 340 313 beschreibt sonnenstrahlungsabweisende Überzüge für Schiffe, Tanks, Gebäude und dergleichen, um ihre Erwärmung in der Sonne zu vermindern. Die Überzüge enthalten ein Bindemittel, ein hitzereflektierendes Pigment und gegebenen- falls beliebige Farbpigmente.EP-A 340 313 describes solar radiation-resistant coatings for ships, tanks, buildings and the like in order to reduce their heating in the sun. The coatings contain a binder, a heat-reflecting pigment and, if necessary, any color pigments.
Nach EP-A 428 937 werden Polyethylenbahnen für Gewächshäuser durch Streichen oder Spritzen mit einem Überzug versehen, der lichtreflektierende Pigmente in einer Matrix aus einem Lackbindemittel enthält. Da die Pigmentteilchen durch das Auf- tragsverfahren nicht orientiert werden, haben sie nur eine schattierende Wirkung und ergeben eine unbefriedigende Transmission. Infolge der geringen Haftng üblicher Lackbindemittel an Polyethylen kann die Beschichtung leicht mit einem Wasserstrahl von der beschichteten Bahn abgewaschen werden.According to EP-A 428 937, polyethylene sheets for greenhouses are provided with a coating by brushing or spraying, which contains light-reflecting pigments in a matrix of a paint binder. Since the pigment particles are not oriented by the application process, they only have a shading effect and result in unsatisfactory transmission. As a result of the low adhesion of conventional paint binders to polyethylene, the coating can easily be washed off the coated web with a water jet.
EP-A 0 548 822 beschreibt PMMA-Platten, die in der Coextrusions-Schicht spezielleEP-A 0 548 822 describes PMMA sheets which are special in the coextrusion layer
Pigmente enthalten. Diese Pigmente bestehen aus einem Trägermaterial z.B. aus Glimmer das mit einer Titandioxidschicht bedeckt ist.Pigments included. These pigments consist of a carrier material e.g. made of mica covered with a layer of titanium dioxide.
EP-A 0 774 551 beschreibt verschiedene Arten von coextrudierten Polycarbonat- platten, die mehrere Coextrusionsschichten enthalten können. Jede einzelne Coextru- sionsschicht gibt der Platte unterschiedliche Funktionalitäten. Für Außenanwendungen ist es wichtig, dass die pigmenthaltige Schicht mit einer darüber liegenden UV-Schutzschicht bedeckt ist, da die Witterungsstabilität der Pigmente in Polycarbonat nicht ausreichend ist. Die darüber liegende UV-Schutzschicht bewahrt die Platte somit vor einer starken Vergilbung.
Die Mehrschichtcoextrusion ist umständlich und teuer, da mindestens zwei verschiedene Coextrusionsformmassen hergestellt werden müssen und mindestens 2 Coextruder an den Hauptextruder angeschlossen werden müssen.EP-A 0 774 551 describes various types of coextruded polycarbonate sheets which can contain several coextrusion layers. Each individual coextrusion layer gives the plate different functions. For outdoor applications, it is important that the pigment-containing layer is covered with an overlying UV protective layer, since the weather stability of the pigments in polycarbonate is not sufficient. The UV protection layer on top protects the plate from severe yellowing. The multilayer coextrusion is cumbersome and expensive, since at least two different coextrusion molding compounds have to be produced and at least 2 coextruders have to be connected to the main extruder.

Das erfindungsgemäße mehrschichtige Pigment kann auch so aufgebaut sein, dass statt der Schichten aus Titandioxid Schichten aus anderen Metalloxiden mit hoherThe multilayer pigment according to the invention can also be constructed such that instead of the layers made of titanium dioxide, layers made of other metal oxides with high

In addition to silicon dioxide, this is, for example, aluminum oxide, aluminum oxide hydrate, boron oxide or a mixture thereof.

Da die herkömmlichen Pigmente und die erfmdungsgemäß einzusetzenden Pigmente einen ähnlichen Aufbau haben und beide Pigmente an der Außenseite Titandioxid enthalten, lag es nicht nahe die erfmdungsgemäßen Pigmente einzusetzen, vor allem weil diese schwieriger herzustellen sind und daher teurer sind.Since the conventional pigments and the pigments to be used according to the invention have a similar structure and both pigments contain titanium dioxide on the outside, it was not obvious to use the pigments according to the invention, above all because they are more difficult to manufacture and therefore more expensive.
