Description
Verfahren, zur Herstellung von Leimungsmittelnfür Papiererzeugnisse und Faserplatten Zur I.ieiiimung von Papiererzewgnnsisen und: auch Faserplatten werden hauptsächlich Harzleime verwendet. Diese bilden je nach Verseifwngsigrald und Konzentration des Harzes braune Massen oder weißliche Dispersionen, in dienen zumindest ein Teil dies Harzes alis Alkaln-resinat vorliegt. Bei, ihrer Verwendung werden sie im Tfapierstoff mit Tonerdiesulfat ausgefällt und umgesetzt.Process for the production of sizing agents for paper products and fibreboard For the sizing of paper ore and: also fibreboard Resin glue is mainly used. These form depending on the saponification scale and concentration of the resin brown masses or whitish dispersions, in serve at least part of this resin is present as alkali resin. At, their use they are precipitated and converted in the paper material with alumina sulphate.
Es sind Versuche bekanntgeworden, sogenanute saure Harzleime herzustellen, die gleichzeitig sowohl Harz und Resinate in feinverteilter Form alis auch das notwendige Tonerde:salz enthalten, indem Harzseüfen oder -dispers:ionen, in Gegenwart von Schutzkolloiden mit Tonerdesalz umgesetzt wurden. Weiterhin w;wrdre-n Versuche unternommen, allerdings ohne praktisches 'bei, denen Freiihiarzd!näpers:ionen,duroh Vermahlen von Harz in wäßriiger Suspension mittels KoliloiidimüMen ehergestellt werden sollten. Es entsiteben hierbei sedimentierende Dispersionen geringer und Kouzenteation und daher ungenügender Handelsfähigkeit.Attempts have become known to produce so-called acidic resin glues, the at the same time both resin and resinate in finely divided form as well as the necessary Alumina: contain salt by adding resinous or dispersing ions, in the presence of protective colloids have been reacted with alumina salt. Further attempts were made, however without practicality, which Freiihiarzd! npers: ions, duroh grinding resin in aqueous suspension should be prepared by means of coliloid dimes. It releases here sedimenting dispersions less and Kouzenteation and therefore inadequate Tradability.
Dias Ziel ides vorlie@geinden Verfahrens bilidet die Herstellung vorn Harz- und Resmnedispe@rsionen, vornehmlich -in fester, konzentrierter und versandfähiger Farm, die neben: Harz gleichzeitig das zur Leimurig erforderliche Salz mieihrwertiger Metalle enthalten können. Es wurde gefunden, daß sich pnakbiis:ch verwendbare Harz- und Resinabdüspersionen erzeugen lassen, wenn Harz einer Fe nstmahlung unter geeigneten Umsiäshden und, in entsprechenden Vorrichtungen unterworfen wird, wobei gleichzeitig oder anechließenrd dlwTch Vermischen mit geeigneten Zusätzen- ein: Verkleben und Verbacken der HarzteiIchen verhindert wird.The aim of the present process is the production in front Resin and Resmnedispe @ rsionen, mainly -in solid, concentrated and dispatchable Farm, which in addition to: resin at the same time the salt required for Leimurig inferior May contain metals. It was found that pnakbiis: ch Generate usable resin and resin diffusion when resin is finely ground subject to suitable conditions and appropriate devices, with simultaneous or subsequent dlwTch mixing with suitable additives- on: The resin particles sticking and caking is prevented.
Bekanntlilch ;lasse. sieh idne normalen Naturharze und auch- viele Kunstharze nur schwierig wuf hohe Feinheit zerkleinern, idia sie in der Maivorrichtung verkleben und verschmieren. Durch: Ausfüh.rungdes Mahlvorganges ibei Temperaturen unter 2i51°, vornellmlich: untrer rco°, wird; verfahrensgemäß ein hoch, disperses Harzpulver z. B. @in Kugel-, Viibrationsodier Sichtmühlen erzeugt.Well known; let. see normal natural resins and also - many Synthetic resins are difficult to grind because of the high fineness, i.e. in the corn fixture stick together and smear. By: Executing the grinding process at temperatures below 2i51 °, usually: below rco °, becomes; according to the method, a highly disperse one Resin powder z. B. @in ball, vibration-eroding sight mills.
Derart erzeugte Harz- und; Resinatpulver eiiud beschriähkt lagerbeständig: Verfahrensgemäß wenden ,daher ,die Harzpulver während oder nach: der Herstellung als disperse Phase in geeignete Schutzstoffe, die vornehmlich gleichzeitig Tonezidesial!z enthalten können, eingearbeitet. Dies kann erfolgen beispielsweise durch- Einmischen in: tonerideis;ajIzhaltige Schutzkolloidlösungen von Leim, Stärke, Polyvinylalkohal u. ä. Weiterhin kann dhteis. aesehehen ,durch Vermischen mit pulverfärmibgn Stoffen oder insbesondere mit abbindenden, homogene Massen; ,bildenden lässlichen Salzen und Salzgemischen. Ein Gemenge ,aus Harzpulver und konzentriertem Tonerdesul!fat bindet nach Zusatz von wenig Wasser zu, einer homogenen, festen Masse ab, idhe das Harzpulver als, düsperse Phase und dhs als Hydrat erstarrende Tonerdesiulfat als D.ispers--ionsmittei enthäflt.Resin and so produced; Resinate powder has a limited shelf life: According to the process, therefore, turn the resin powder during or after: the production as a disperse phase in suitable protective substances, which are mainly at the same time Tonezidesial! may contain, incorporated. This can be done, for example, by mixing in in: tonerideis; ajIzhaltige protective colloid solutions of glue, starch, polyvinyl alcohol and the like. Furthermore, dhteis. aeshehen, by mixing with powdered substances or in particular with setting, homogeneous masses; , forming venous salts and salt mixtures. A mixture of resin powder and concentrated clay sulfate binds to a homogeneous, solid mass after adding a little water, i Resin powder as, düsperse phase and ie as hydrate solidifying alumina sulfate as Contains dispersing agent.
Die Arbeitsweisse gestattet somit auch die Herstellung fester, handelisfähiger Harzleimungsmittel, die gleichzeitig-,die zur Leimeng erforderlichen Tonerdesialze enthalten.The way of working thus also allows the production of stronger, more tradeable products Resin sizing agents, which at the same time, the alumina salts required for gluing contain.
