Description
'7909585-7 Masterbatchen enligt uppfinningen kan emellertid som ovan omtalats innehålla pignent, modifieringsmedel eller både pigment och modifieringsmedel. However, as mentioned above, the masterbatch of the invention may contain pigment, modifier or both pigment and modifier.
Pigment för ovan nämnda pigmentmasterbatcher framställes bl.a. genom att man blandar olika lösningar, varvid en fällning av pigmentpartiklar med en storlek lägre än i_um erhålles. Denna fällning filtreras och pressas till en s.k. pignentpresskaka. Presskakan torkas och mals sedan till en partikelstorlek av 40-50 pm. I regel sker ovanstående tillverkningssteg hos pignenttillverkaren.Pigments for the above-mentioned pigment masterbatches are prepared i.a. by mixing different solutions, whereby a precipitate of pigment particles with a size lower than i_um is obtained. This precipitate is filtered and pressed into a so-called pignentpresskaka. The press cake is dried and then ground to a particle size of 40-50 μm. As a rule, the above manufacturing steps take place at the patent manufacturer.
Den fortsatta bearbetningen av de malda pigmentpartiklarna till en pigment- masterbatch sker sedan vanligen hos speciella masterbatchtillverkare. Hos J dessa knådas det malda pigmentet under vänue i högmolekylära polymerer i speciella maskiner så att pigmentpartikelstorleken nedbringas till exempelvis 5-l0_um.The further processing of the ground pigment particles into a pigment masterbatch then usually takes place with special masterbatch manufacturers. In these, the ground pigment is kneaded under venue in high molecular weight polymers in special machines so that the pigment particle size is reduced to, for example, 5 to 10 .mu.m.
I förut kända masterbatcher består bäraren vanligen av lågdensitet polyeten, högdensi tet polyeten, polypropen, etylen/vinylacetatsampolymerer etc. En nackdel med en sådan masterbatch är att den oftast bara kan användas för infärgning av en enda polymertyp, nämligen den som motsvarar bäraren i masterbatchen. Den plastbearbetande industrin har därför behövt ett ganska i stort sortiment av masterbatcher innehållande olika bärarmaterial och olika färgnyanser för att kunna bearbeta de förekommande plasterna.In prior art masterbatches, the support usually consists of low density polyethylene, high density polyethylene, polypropylene, ethylene / vinyl acetate copolymers, etc. A disadvantage of such a masterbatch is that it can usually only be used for dyeing a single polymer type, namely the one corresponding to the support in the masterbatch. The plastics processing industry has therefore needed a fairly large assortment of masterbatches containing different carrier materials and different color shades in order to be able to process the existing plastics.
Det är också förut känt att masterbatcher kan innehålla smörjmedel såsom stearinsyra, metallstearat, t.ex. kalcium- eller aluminiumstearat eller vaxer.It is also known that masterbatches may contain lubricants such as stearic acid, metal stearate, e.g. calcium or aluminum stearate or waxes.
D En sådan masterbatch innehåller ofta l-2 viktprocent metallstearat eller l0-l5 viktprocent vax.D Such a masterbatch often contains 1-2% by weight of metal stearate or 10-15% by weight of wax.
Fyllmedlet i en masterbatch kan bestå av exempelvis kalciumkarbonat, lera eller talk. D Vid ovan beskrivna metod för framställning av en masterbatch erhålles som nämnts relativt stora pigmentpartiklar (ca 5-l0 um). Detta är en nackdel.The filler in a masterbatch may consist of, for example, calcium carbonate, clay or talc. In the method described above for the preparation of a masterbatch, as mentioned, relatively large pigment particles (approx. 5-10 μm) are obtained. This is a disadvantage.
Mindre pignentpartiklar ger nämligen en förbättrad färgstyrka vid sænna pigmentmängd.Smaller pigment particles provide an improved color strength with a small amount of pigment.
För att åstadkomma mindre pigmentpartiklar är det förut känt att använda polyetenvax som bärare i en s.k. flushad masterbatch. 79095 85-7 Vid en sådan f1ushningsprocess utgår man från ovan beskrivna pigmentpresskaka.In order to produce smaller pigment particles, it is previously known to use polyethylene wax as a carrier in a so-called flushad masterbatch. 79095 85-7 In such a flushing process, the pigment press cake described above is used.
Utan föregående torkning och malning b1andas denna kaka under knâdning med ett po1yetenvax vid en sådan temperatur att vaxet smäïter (60-700 C). Under knadningsprocessen förträngs vattnet i presskakan så att primärpartik1ar av pignentet med en stor1ek av endast ca 1-5 pm och oms1utna av partik1ar av po1yetenvax erhâ11es. Vattnet av1ägsnas från smä1tan som sedan ky1s under omrörning så att en krossad masterbatch erhä11es.Without prior drying and grinding, this cake is mixed during kneading with a polyethylene wax at such a temperature that the wax melts (60-700 ° C). During the kneading process, the water in the press cake is displaced so that primary particles of the pigment with a size of only about 1-5 microns and enclosed by particles of polyethylene wax are obtained. The water is removed from the melt which is then cooled with stirring to give a crushed masterbatch.
Denna f1ushningsprocess ger som nämnts mycket små pigmentpartik1ar. Det poiy- etenvax som använts ger eme11ertid samtidigt försämrade fysika1iska egenskaper hos den framstä11da piastprodukten. Dessutom kan en sådan masterbatch endast användas för infärgning av poïyetenpïast.As mentioned, this flushing process produces very small pigment particles. The polyethylene wax used, however, at the same time imparts deteriorating physical properties of the produced piast product. In addition, such a masterbatch can only be used for staining polyethylene plaster.
Det finns en1igt ovan ett stort behov av en masterbatch innehå11ande en mer universe11 bärare som gör att en enda masterbatch kan användas tiïïsammans med många olika p1aster. Pigmentpartikïarna i en sådan masterbatch bör också vara mycket små. 1 Genom före1iggande uppfinning har man kunnat ti11fredsstä11a nämnda behov och åstadkommit en för plaster avsedd fïushad masterbatch i f0rfl1 av Qrflfuller eller korn innehållande åtminstone ett pigment Och/eller modifie- ríngsmedel samt en organisk bärare för dessa. Masterbatciien känne- šâcšåâítgänâštöešgâgïgašâgiïöåoge delvis består av polybuten med Förutom po1ybuten kan bäraren även innehå11a ett e11er f1era andra organiska material såsom 1âgdensitet (Ld) po1yeten, högdensitet (Hd) poïyeten, po1y~ Styren, po1ypropen, akryïnitri1butadienstyrensampo1ymerer (ABS), etenvinyï- acetatsampo1ymerer (EVA) e11er 1âgmo1eky1ärt po1yo1efinvax.According to the above, there is a great need for a masterbatch containing one more universe11 carrier which means that a single masterbatch can be used together with many different patches. The pigment particles in such a masterbatch should also be very small. By means of the present invention it has been possible to satisfy the said needs and to provide a plastic masterbatch intended for plastics in the form of Qr fl fuller or barley containing at least one pigment and / or modifier and an organic carrier therefor. Masterbatciien känne- šâcšåâítgänâštöešgâgïgašâgiïöåoge partially of polybutylene with addition po1ybuten carrier can also innehå11a a e11er f1era other organic materials such as 1âgdensitet (Ld) po1yeten, high density (HD) poïyeten, po1y ~ Styrene, po1ypropen, akryïnitri1butadienstyrensampo1ymerer (ABS), etenvinyï- acetatsampo1ymerer (EVA ) e11er 1âgmo1eky1ärt po1yo1efinvax.
Med förde1 utgöres 10-100 viktprocent, företrädesvis 25-90 viktprocent av bäraren av po1ybuten. Å Bäraren utgör 1ämp1igen 90-20 viktprocent av masterbatchen en1igt uppfinningen.With advantage 1 is 10-100% by weight, preferably 25-90% by weight of the carrier of polybutene. The carrier constitutes at least 90-20% by weight of the masterbatch according to the invention.
Po1ybutenet som ingår i bäraren ti11 den patentsökta flushade masterbatchen har he1t unika egenskaper i sammanhanget. För det första försämras inte de fysika1iska egenskaperna hos de framstä11da p1astprodukterna vid användning av före1iggande masterbatch. D _ a*79o9sss-7 Dessutom kan flera olika plaster såsom polyeten, polystyren, polypropen, akrylnitrilbutadienstyrensampolymerer (ABS) och etenvinylacetatsampolymerer infärgas med sama masterbatch innehållande polybuten som bärare.The polybutene included in the carrier for the patent-pending flushed masterbatch has unique properties in this context. First, the physical properties of the plastic products produced do not deteriorate when using the present masterbatch. D _ a * 79o9sss-7 In addition, several different plastics such as polyethylene, polystyrene, polypropylene, acrylonitrile butadiene styrene copolymers (ABS) and ethylene vinyl acetate copolymers can be dyed with the same masterbatch containing polybutene as carrier.
Slutligen ger en flushad produkt som nämnts betydligt finkornigare pigment- partiklar än ett konventionellt framställningsförfarande.Finally, a flushed product mentioned yields significantly finer-grained pigment particles than a conventional manufacturing process.
Uppfinningen förklaras nännare i anslutning till nedanstående utföringsexempel som visar framställning av en pigmentmasterbatch enligt en utföringsform av uppfinningen.The invention is explained in more detail in connection with the following exemplary embodiments which show the preparation of a pigment masterbatch according to an embodiment of the invention.
Exempel I en mantlad blandare, s.k. flushningsknâdare försedd med knådningsarmar och lock för hermetisk tillslutning av blandaren, satsades l55 kg av en pignent- presskaka bestående av 40 viktprocent av ett organiskt eller oorganiskt pignent och resten vatten. Dessutom satsades 20 kg vatten, l45 kg polybuten samt ytaktivt medel. Locket sattes på blandaren som därefter värmdes upp till en temperatur överstigande polymerens smältpunkt, vilken ligger mycket över vattnets kokpunkt. Därvid förträngdes vattnet i pigmentpresskakan under en s.k. flushningsprocess så att primärpartiklar av pignentet med en storlek av ca l um omslöts av polymerpartiklar och vattnet förelåg i vätske- eller ångform utanför smältan. Sedan avluftades blandaren, varvid vattenângan avlägsnades. Med hjälp av en ansluten vakuumpump avlägsnades resterande kapillärt bundet vatten från smältan. Därpå kyldes smältan under omrörning med hjälp av knådningsannarna. Den stelnande polymer/pigmentblandningen, D _ s.k. masterbatchen, krossades därvid. 210 kg masterbatch erhölls.Example I A jacketed mixer, so-called flushing kneader equipped with kneading arms and lid for hermetic closure of the mixer, 155 kg of a pignent press cake consisting of 40% by weight of an organic or inorganic pignent and the rest water were charged. In addition, 20 kg of water, 145 kg of polybutene and surfactant were invested. The lid was placed on the mixer which was then heated to a temperature above the melting point of the polymer, which is well above the boiling point of the water. Thereby, the water in the pigment press cake was displaced during a so-called flushing process so that primary particles of the pigment with a size of about 1 μm were enclosed by polymer particles and the water was in liquid or vapor form outside the melt. The mixer was then vented, removing the water vapor. Using a connected vacuum pump, the remaining capillary-bound water was removed from the melt. The melt was then cooled with stirring by means of the kneading agents. The solidifying polymer / pigment mixture, D masterbatch, was thereby crushed. 210 kg masterbatch was obtained.
Uppfinningen är inte begränsad till den visade utföringsformen, då denna kan modifieras på olika sätt inom uppfinningens ram.The invention is not limited to the embodiment shown, as this can be modified in various ways within the scope of the invention.
