Description
Verfahren zur Herstellung pigmenthaltiger Folien Für viele Zwecke ist es nötig oder vorteilhaft, einer an sich glasklaren Folie Pigmente einzuverleiben.Process for the production of films containing pigments For many purposes it is necessary or advantageous to incorporate pigments into a film which is actually crystal clear.
Solche gefärbte Folien werden in der Verpackungsindustrie, für Kaschierungszwecke, als Unterlage für photographische Filme und Magnettonfilme venvendet.Such colored films are used in the packaging industry, for lamination purposes, used as a base for photographic films and magnetic sound films.
Werden solche Folien, wie meist, nach dem Gießverfahren hergestellt, so kann man zwar in dem verwendeten Lösungsmittel lösliche organische Farbstoffe der Gieslösung zusetzen. Solche Färbungen sind aber meist sehr wenig intensiv, da die Leuchtkraft dieser Farbstoffe in der Folie gering ist. In solchen Fällen ist es zweckmäßig, die Leuchtkraft durch Zugabe eines Pigmentes, z. B. eines Weißpigmentes, zu erhöhen. Die Verarbeitung solcher pigmenthaltigen Lösungen macht insofern Schwierigkeiten, als das Pigment in dem Lösungsmittel, aus dem die Folie gegossen wird, z. B. Methylenchlorid, zusammenflockt. Dadurch wird die Filtration sehr erschwert und keine gleichmäßige Färbung erzielt. Schließlich wird durch soIche Zusammenflockungen die Gleichmäßigkeit der mechanischen Qualität gestört. Es wurde bereits vorgeschlagen, zur Herstellung von pigmenthaltigen Folien die Pigmente in Form von Zubereitungen zu verwenden, die durch im plastischen Zustand erfolgende intensive mechanische Bearbeitung der Pigmente mit Trägerstoffen, gegebenenfalls unter Mitverwendung einer Flüssigkeit, gewonnen werden.If such films, as is usually the case, are manufactured using the casting process, so you can indeed in the solvent used soluble organic dyes add to the pouring solution. However, such colorations are usually not very intense because the luminosity of these dyes in the film is low. In such cases it is it is useful to increase the luminosity by adding a pigment, e.g. B. a white pigment, to increase. The processing of such pigment-containing solutions causes difficulties insofar as than the pigment in the solvent from which the film is cast, e.g. B. methylene chloride, flakes together. This makes the filtration very difficult and not a uniform one Coloring achieved. Ultimately, it is through such flocculation that evenness is achieved the mechanical quality disturbed. It has already been suggested for manufacture to use the pigments in the form of preparations from pigment-containing films, the intensive mechanical processing that takes place in the plastic state Pigments with carriers, if necessary with the use of a liquid, be won.
Weiterhin ist es bekannt, zur Dispergierung von Pigmenten in plastischen Massen verhältnismäßig große Mengen des Kondensationsproduktes aus Alkylenoxyden und isocyclischen Oxyverbindungen zu verwenden. It is also known to disperse pigments in plastic Masses of relatively large amounts of the condensation product of alkylene oxides and isocyclic oxy compounds.
Es wurde nun gefunden, daß sich pigmenthaltige Folien durch Vergießen von pigmentierten Lösungen filmbildender Stoffe herstellen lassen, wenn man eine Gießlösung verwendet, der eine durch mechanische Bearbeitung eines Pigmentes mit einem Alkylharz als Dispergierungsmittel in Gegenwart eines Weichmachers und/oder eines Lösungsmittels erhaltene Pigmentpaste zugesetzt worden ist. Als besonders geeignet haben sich vor allem die ölmodifizierten Alkydharze bewährt, welche z. B. aus Phthalsäure, einem mehrwertigen Alkohol (beispielsweise Glycerin, Trimethylolpropan, Pentaerythrit) einerseits, Ricinen- oder Sojaölfettsäure andererseits erhalten werden. Der Gießlösung können gegebenenfalls lösliche organische Farbstoffe zugesetzt werden. Die Art und Menge des verwendeten Weichmachers richtet sich nach der gewünschten Folienqualität. Das Verhältnis Titandioxyd zu dem Alkydharz kann zwischen etwa 40 bis 65 Teilen Titandioxyd und 1 bis 10 Teilen Alkydharz schwanken. It has now been found that pigment-containing films can be cast by potting of pigmented solutions of film-forming substances, if you have a Casting solution used, the one made by mechanical processing of a pigment with an alkyl resin as a dispersant in the presence of a plasticizer and / or pigment paste obtained from a solvent has been added. As special Especially the oil-modified alkyd resins have proven suitable, which z. B. from phthalic acid, a polyhydric alcohol (e.g. glycerine, trimethylolpropane, Pentaerythritol) on the one hand, and ricinic or soybean oil fatty acid on the other hand. Soluble organic dyes can optionally be added to the casting solution. The type and amount of plasticizer used depends on the desired Foil quality. The ratio of titanium dioxide to the alkyd resin can be between about 40 up to 65 parts of titanium dioxide and 1 to 10 parts of alkyd resin vary.
Für die Herstellung der Folien kommen alle film- bildenden Substanzen in Frage, z. B. Celluloseester, Polystyrol, Polycarbonate, Polyester aus Terephthalsäure und Glykolen. For the production of the foils, all film forming substances in question, e.g. B. cellulose esters, polystyrene, polycarbonates, polyesters made from terephthalic acid and glycols.
Beispiel 1 Auf einem Walzenstuhl wird durch mehrstündiges Walzen eine Paste erzeugt, die folgende Zusammensetzung hat: 0,5 g Titandioxyd, 0,24 g Phthalsäure-dibutylester, 0,12 g Triphenylphosphat, 0,11 g Butanol, 0,015 g einer 60°/oigen Lösung eines mit Ricinensäure modifizierten Alkydharzes in Benzol. EXAMPLE 1 Rolling for several hours is carried out on a roller mill produces a paste that has the following composition: 0.5 g titanium dioxide, 0.24 g Dibutyl phthalate, 0.12 g triphenyl phosphate, 0.11 g butanol, 0.015 g of a 60% solution of an alkyd resin modified with ricinenic acid in benzene.
5 kg einer solchen Paste werden folgender Lösung unter häufigem Rühren zugesetzt: 100 kg Acetylcellulose mit 50 bis 60 0h Essigsäure, 10 kg Triphenylphosphat, 0,5 kg »Ceresrot 3 R.« (Color Index, 2. Auflage, Nr. 21260), 500 kg Methylenchlorid, 50 kg Methanol. 5 kg of such a paste become the following solution with frequent stirring added: 100 kg acetyl cellulose with 50 to 60 0h acetic acid, 10 kg triphenyl phosphate, 0.5 kg "Ceresrot 3 R." (Color Index, 2nd edition, No. 21260), 500 kg methylene chloride, 50 kg of methanol.
Diese Lösung läßt sich einwandfrei durch Textil-oder Papierfilter filtrieren. Sie wird nach bekannten Verfahren auf einer Band- oder Trommelmaschine vergossen. Man erhält eine Folie von leuchtendroter Farbe ohne die mindeste Fehlstelle im Farbfilm. Die mechanischen Zerreißwerte sind von denen einer nicht gefärbten Folie nicht zu unterscheiden. This solution can be easily passed through textile or paper filters filter. It is carried out using known methods on a tape or drum machine shed. A film of bright red color is obtained without the slightest defect in color film. The mechanical tear values are one of those not colored Foil indistinguishable.
Beispiel 2 0,35 g Eisenoxydgelb, 0,5 g eines Polycarbonates des Dioxydiphenyldimethylmethans, 0,2 g Chlorbenzol, 0,02 g einer 500/eigen Lösung eines mit Sojaöl modifizierten Alkydharzes werden in einer Schwingmühle bis zur Erreichung des gewünschten Dispersitätsgrades vermahlen. Example 2 0.35 g of iron oxide yellow, 0.5 g of a polycarbonate of dioxydiphenyldimethylmethane, 0.2 g of chlorobenzene, 0.02 g of a 500 / own solution of one modified with soybean oil Alkyd resin are in a vibrating mill until the desired degree of dispersion is achieved grind.
4 kg einer solchen Paste werden folgender Lösung unter kräftigem Rühren zugefügt: 100,0 kg Polycarbonat wie obenS 400,0 kg Methylenchlorid, 0,3 kg Ceresblau GCA 7005 (Color Index, 2. Auflage, Nr. 61525). 4 kg of such a paste become the following solution under vigorous Stirring added: 100.0 kg of polycarbonate as above S 400.0 kg of methylene chloride, 0.3 kg Ceres blue GCA 7005 (Color Index, 2nd edition, No. 61525).
Diese Lösung läßt sich einwandfrei filtrieren und zu einer gleichmäßig blauen Folie vergießen. This solution can be filtered properly and becomes a uniform shedding blue foil.
