Description
Vynález sa týká spósobu povrchovéj úpravy pigmentov pre polyolefíny.The invention relates to a process for the surface treatment of pigments for polyolefins.
Farebná sila pigmentov používaných pre farbenie polyolefínov v hmotě závisí od velkosti častíc pigmentu, a teda najmá od schopnosti ich dispergácie v tavenine polyméru. Stupeň disperzity pigmentov je možné zvýšit dispergačnými přísadami (AO 195 089, AO 220 955, AO 220 957), alebo povrchovou úpravou pigmentov (NSR pat. 126 136, US pat. 3 755 244). Najma povrchová úprava pigmentov rieši ich stupeň disperzity v polyolefínoch, pri optimálnych podmienkach mletia na maximálněj úrovni, so zvýšením ich farebnej sily až o 30 %.The color strength of the pigments used for dyeing polyolefins in the mass depends on the size of the pigment particles, and thus in particular on the ability to disperse them in the polymer melt. The degree of dispersion of the pigments can be increased by dispersing additives (AO 195 089, AO 220 955, AO 220 957) or by surface treatment of the pigments (NSR pat. 126 136, U.S. Pat. No. 3,755,244). In particular, the surface treatment of pigments solves their degree of dispersity in polyolefins, under optimal grinding conditions at the maximum level, with an increase in their color strength by up to 30%.
Okrem zvýšenia farebnej sily pigmentu povrchová úprava rieši tiež niektoré áalšie otázky, a to najma ulahčenie separácie pigmentov z vodnej fázy, zlepšenie podmienok pri sušení a tiež umožňuje netradičnú aplikáciu týchto pigmentov pre priame farbenie (až 50 % disperziami) polyolefínov bez predbežnej přípravy koncentrátov. Povrchová úpravu pigmentov vo vodě nerozpustnými dispergátormi na báze polyoxyalkylénglykolov, ich kopolymérov a derivátov viacmocných alkoholov a karboxylových kyselin riešia AO 245 098, AO 245 096. Aj ked sa pri týchto postupoch dosahujú dobré výsledky z hladiska farebnej výdatnosti pigmentov, nevýhodou týchto postupov je nie celkom uspokojivá separácia pigmentov z vodnej fázy a v niektorých prípadoch plastický charakter upravenéj zmesi, ktorou je na súčasných zariadeniach obtiažná manipulácia.In addition to increasing the color strength of the pigment, the surface treatment also addresses some other issues, in particular facilitating the separation of pigments from the aqueous phase, improving drying conditions and also allowing non-traditional application of these pigments for direct dyeing (up to 50% dispersions) of polyolefins without prior preparation of concentrates. Surface treatment of pigments with water-insoluble dispersants based on polyoxyalkylene glycols, their copolymers and derivatives of polyhydric alcohols and carboxylic acids is solved by AO 245 098, AO 245 096. Although good results are obtained in these processes in terms of color yield of pigments, the disadvantage of these processes is not quite satisfactory separation of pigments from the aqueous phase and in some cases the plastic nature of the treated mixture, which is difficult to handle on current equipment.
Podstata spósobu povrchovej úpravy pigmentov pre polyolefíny podlá vynálezu spočívá v tom, že pigment sa melie vo vodnom prostředí a homogenizuje pri teplote 70 až 100 °C s roztavenou trojzložkovou zmesou vysokomolekulového polyolefínu s molekulovou hmotnosťou 2 000 až 50 000, dialkylftalátu s počtom uhlíkov v alkylreťazci 4 až 8 alebo neprchavého alkylderivátu fenolu alebo benzofenónu s počtom uhlíkov v alkylreťazci 4 až 35 a nízkomolekulového polyolefínu s molekulovou hmotnosťou 600 až 1 500, v pomere od 2,3:0,7:2 do 2:2:1 hmot, dielov. Po ochladení vznikne jemná granulovaná disperzia pigmentu, ktorá sa oddělí a vysuší za zníženého tlaku do konštantnej hmotnosti.The process for the surface treatment of pigments for polyolefins according to the invention is that the pigment is ground in an aqueous medium and homogenized at 70 to 100 ° C with a molten three-component mixture of a high molecular weight polyolefin having a molecular weight of 2,000 to 50,000, dialkyl phthalate with carbon number in the alkyl chain. 4 to 8 or a non-volatile alkyl derivative of phenol or benzophenone having a carbon number in the alkyl chain of 4 to 35 and a low molecular weight polyolefin having a molecular weight of 600 to 1,500, in a ratio of 2.3: 0.7: 2 to 2: 2: 1 parts by weight. After cooling, a fine granular pigment dispersion is formed, which is separated and dried under reduced pressure to constant weight.
Namiesto dialkylftalátu je možné použiť aj iné aromatické deriváty, ako alkylované fenoly, napr. 2,5-ditercbutylfenol, alebo alkylované benzofenóny, napr. 1-hydroxy-4-oktoxybenzofenón, ktoré sú miešatelné vo vysokom zastúpení s polyolefínom a majú schopnost znižovať jeho maximálnu teplotu krystalizácie alebo teplotu topenia, pričom sa vylučujú prchavé aromatické rozpúšťadlá, napr. xylén a jeho deriváty. 'Instead of dialkyl phthalate, it is also possible to use other aromatic derivatives, such as alkylated phenols, e.g. 2,5-ditert-butylphenol, or alkylated benzophenones, e.g. 1-hydroxy-4-octoxybenzophenone, which are miscible in high proportion with the polyolefin and have the ability to lower its maximum crystallization temperature or melting point, while excluding volatile aromatic solvents, e.g. xylene and its derivatives. '
Ako povrchovoaktívne látky sa pri mletí pigmentu použijú neiónogenné látky například polyoxyalkylonglykoly a ich deriváty v koncentrácii do 20 % hmot. Koncentrácia pigmentu sa pri mletí vo vodnom prostředí je 4 až 40 í hmot.Nonionic substances, for example polyoxyalkylene glycols and their derivatives, are used as surfactants in the grinding of the pigment in a concentration of up to 20% by weight. The concentration of the pigment when grinding in an aqueous medium is 4 to 40% by weight.
K výhodám uvedeného postupu patří vznik povrchovo upraveného pigmentu s odstránenou prašnosťou, vo forme jemných hydrofóbnych granuliek s priemerom pod 1 mm, s velmi vhodnou konzistenciou na přípravu farebných koncentrátov so zvýšenou farebnou silou a dobrou dispergovatelnosťou v polyolefínoch. postup je zvlášť vhodný pre diazokondenzačné a antrachinónové pigmenty. Povrchovo upravený pigment je možné aplikovat pri farbení polyolefínov v hmotě, pri príprave farebných koncentrátov bez alebo s použitím dispergátorov alebo použiť na priame farbenie bez přípravy koncentrovaných aisperzií.The advantages of this process include the formation of a surface-treated pigment with dust removal, in the form of fine hydrophobic granules with a diameter below 1 mm, with a very suitable consistency for the preparation of color concentrates with increased color strength and good dispersibility in polyolefins. the process is particularly suitable for diazocondensation and anthraquinone pigments. The surface-treated pigment can be applied in the dyeing of polyolefins in bulk, in the preparation of color concentrates without or with the use of dispersants or used for direct dyeing without the preparation of concentrated dispersions.
