Flexible Verpackungsdruckfarben bestehen haupts\u00e4chlich aus Farbf\u00fcllern, Bindeharzen, Additiven (einschlie\u00dflich Verlaufsmitteln, Entsch\u00e4umern, UV-Absorbern, Wachszus\u00e4tzen usw.) und L\u00f6sungsmitteln. Entsprechend den verschiedenen L\u00f6semittelsystemen lassen sich die auf dem Markt befindlichen Druckfarben f\u00fcr flexible Verpackungen in benzoll\u00f6sliche Druckfarben, esterl\u00f6sliche Druckfarben, alkoholl\u00f6sliche Druckfarben und Druckfarben auf Wasserbasis unterteilen. Tinten auf L\u00f6sungsmittelbasis wurden aufgrund von Benzol, Ketonen und anderen gef\u00e4hrlichen Bestandteilen aus dem Verkehr gezogen; Tinten auf Wasserbasis sind eine neue Generation umweltfreundlicher Tinten ohne VOC, die im Rahmen der nationalen Politik und der Entwicklung von Technologien zur F\u00f6rderung der raschen Entwicklung eingesetzt werden. Aufgrund der Auswirkungen von Technologie, Kosten und Ausr\u00fcstung und anderen Faktoren ist Tinte auf Wasserbasis jedoch auf dem Markt nicht weit verbreitet. Daher wird alkoholl\u00f6sliche Tinte (insbesondere alkoholl\u00f6sliche Polyurethan-Tinte) auch in der kommenden Zeit eine wichtige Wahl f\u00fcr Verpackungsunternehmen bleiben.<\/p>\n<p>Erstens, die Art der alkoholl\u00f6slichen Tinte und die Leistung.<\/p>\n<p>Alkoholl\u00f6sliche Tinte bezieht sich auf die Verwendung von alkoholischen L\u00f6sungsmitteln, mit denen Tinte aufgel\u00f6st und verd\u00fcnnt werden kann. Tinte kann mit alkoholischen L\u00f6sungsmitteln aufgel\u00f6st werden, wobei das Verbindungsmaterial Harz eine entscheidende Rolle spielt. Die derzeit auf dem Markt gebr\u00e4uchliche alkoholl\u00f6sliche Tinte kann je nach Harzverbindungsmaterial in alkoholl\u00f6sliche Acryltinte, alkoholl\u00f6sliche Polyamidtinte und alkoholl\u00f6sliche Polyurethantinte unterteilt werden.<\/p>\n<p>1, Acryl-alkoholl\u00f6sliche Tinte. Acrylharz hat eine gute Transparenz, hohe mechanische Festigkeit, gute Haftung an der Folie und andere Eigenschaften und kann mit einer Vielzahl von Harzen wie Nitrocellulose, Celluloseacetatbutyrat, Vinylharz usw. kompatibel sein. Die mit ihnen hergestellten Tiefdruck- oder Flexodruckfarben zeichnen sich durch gute Farbentwicklung, Abriebfestigkeit und starke Haftung auf den Substraten aus. Da das Acrylharz jedoch oft eine unvollst\u00e4ndige Reaktion des Acrylmonomers enth\u00e4lt, entsteht ein starker Geruch.<\/p>\n<p>2, Polyamid-basierte alkoholl\u00f6sliche Tinte. Polyamidharz hat hohen Glanz, gute Abriebfestigkeit, gute Z\u00e4higkeit und andere Eigenschaften, aber auch mit einer Vielzahl von Harzen, wie Fumars\u00e4ureharz, Nitrocellulose und andere gemischte Verwendung. Die mit Polyamidharz hergestellte Tinte hat eine ausgezeichnete Farbe, gute Best\u00e4ndigkeit und Abriebfestigkeit und wird h\u00e4ufig als Tiefdruck- oder Flexodruckfarbe und Lack verwendet. Allerdings ist die Temperaturbest\u00e4ndigkeit von Polyamidharz schlecht, die Gefrierbest\u00e4ndigkeit bei niedrigen Temperaturen und die Kochbest\u00e4ndigkeit bei hohen Temperaturen sind nicht gut, so dass die alkoholl\u00f6sliche Polyamidtinte \u00fcblicherweise in gew\u00f6hnlichen Leichtverpackungen verwendet wird.<\/p>\n<p>3, Polyurethan-Typ alkoholl\u00f6sliche Tinte. Polyurethanharz hat eine ausgezeichnete Flexibilit\u00e4t, Festigkeit und Temperaturbest\u00e4ndigkeit. Polyurethan kann auch mit Polyketonharzen, Acrylharzen, Nitrocellulose, Vinylharzen und vielen anderen Harzen gemischt verwendet werden. Die mit Polyurethanharz hergestellte alkoholl\u00f6sliche Tinte hat eine gute Flexibilit\u00e4t, eine gute Temperaturbest\u00e4ndigkeit, einen geringen Geruch und eine gute Best\u00e4ndigkeit des Substrats. Sie kann nicht nur f\u00fcr gew\u00f6hnliche Leichtverpackungen verwendet werden, sondern auch f\u00fcr Verpackungen, die bei hohen Temperaturen gekocht oder bei niedrigen Temperaturen eingefroren werden.<\/p>\n<p>Zweitens, die Rolle des Polyurethanharzes bei den Eigenschaften der alkoholl\u00f6slichen Tinte. Die Eigenschaften und das Verh\u00e4ltnis von weichen und harten Segmenten in der Molekularstruktur des Polyurethanharzes bestimmen die verschiedenen Eigenschaften und Verwendungen des Harzes. Polyurethanharz als Verbindungsmaterial f\u00fcr die alkoholl\u00f6sliche Tinte spielt die folgenden Rollen.<\/p>\n<p>1\u3001Verbesserung der Flexibilit\u00e4t. Einige Nitrocellulose, Acrylharz als Verbindungsmaterial f\u00fcr die Tinte, der Film ist oft hart und spr\u00f6de, nicht geeignet f\u00fcr den Einsatz in flexiblen Verpackungen Tinte allein, die Notwendigkeit, Weichmacher oder Weichmacher Harz hinzuf\u00fcgen, um die Flexibilit\u00e4t des Harzes zu verbessern. Die meisten Weichmacher sind aufgrund der gesundheitlichen Gefahren f\u00fcr den Menschen in Lebensmittelverpackungsdruckfarben verboten. Polyurethanharz hat ausgezeichnete weichmachende Eigenschaften und kann Weichmacher ersetzen, um die Flexibilit\u00e4t von Nitrocellulosetinte zu erh\u00f6hen, so dass sie in einer Vielzahl von Kunststoffverpackungssubstraten verwendet werden kann. Au\u00dferdem ist Polyurethanharz sicher und umweltfreundlich und entspricht den nationalen Vorschriften zur Lebensmittelsicherheit.<\/p>\n<p>2\u3001Verbesserung der Adh\u00e4sion. Die Molekularstruktur von Polyurethanharz enth\u00e4lt eine gro\u00dfe Anzahl polarer COO-, -NHCOO- und -NHCONH-Gruppen, die intermolekulare Wasserstoffbr\u00fcckenbindungen mit -OH, -NH- auf der Oberfl\u00e4che von koronabehandeltem PET, PE, NY und anderen Substraten bilden k\u00f6nnen, um die Haftung der Tinte auf Kunststoffsubstraten zu verbessern.<\/p>\n<p>3\u3001Verbesserung der Temperaturbest\u00e4ndigkeit. In der Molekularstruktur von Polyurethan gibt es eine gro\u00dfe Anzahl polarer Gruppen, die die Koh\u00e4sionsfestigkeit und die thermische Stabilit\u00e4t des Harzes verbessern k\u00f6nnen, so dass die Tinte in kochfesten Verpackungen bei hohen Temperaturen verwendet werden kann.<\/p>\n<p>4\u3001Verbesserung der L\u00f6slichkeit. Das alkoholl\u00f6sliche Polyurethanharz hat eine gute L\u00f6slichkeit und kann vollst\u00e4ndig mit alkoholischen L\u00f6sungsmitteln aufgel\u00f6st und verd\u00fcnnt werden. Seine Verwendung in alkoholl\u00f6slicher Tinte kann die Wiederaufl\u00f6sbarkeit der Tinte verbessern und das Blockierungsph\u00e4nomen im Druckprozess verhindern.<\/p>\n<h2><strong style=\"font-size: 16px;\"><b>Kontaktieren Sie uns jetzt!<\/b><\/strong><\/h2>\n<h4><strong><b>Wenn Sie COA, MSDS oder TDS ben\u00f6tigen, geben Sie bitte Ihre Kontaktinformationen in das untenstehende Formular ein.
