Abstract
Laky monoazopigmentov patria do kategorie lacných pigmentov, obvykle však citlivých na vyššie teploty pri zapracovávaní do hmoty. Ich uplatnenie pre farbenie náročnějších výrobkov až do teplót 250 °C sa dosiahne prídavkom zinočnatých a horečnatých solí, najma vo formě solí mastných kyselin, ktoré ufahčujú ich dispergáciu v polymére.Monoazopigment varnishes belong to the category cheap pigments, usually sensitive to higher temperatures when working in mass. Their application for more demanding coloring up to 250 ° C by addition of zinc and magnesium salts, especially in the form of the fatty acid salts which they facilitate dispersing them in the polymer.
Description
Vynález sa týká spósobu zvýšenia termostability lakov monoazopigmentov a z nich vyrábaných disperzií, najmá pre farbenie polymérov v hmotě.The invention relates to a method for increasing the thermostability of monoazopigment lacquers and dispersions produced therefrom, in particular for the dyeing of polymers in mass.
Pie farbenie polymérov v hmotě podfa čs. ΛΟ 245 095 a čs. ΛΟ 245 098 sa používajú pigmenty farbív vo vhodných nosičoch. Požiadavkou je vysoká tepelná stálosť farebných pigmentov, nakofko tieto sa pridávajú do taveniny polyméru, ktorej teplota přesahuje až 300 °C v priebehu homogenizácie a ďaišieho spracovania na rózne tvarované výrobky, najmá syntetické vlákna. Organické pigmenty s dobrou dispergovatefnosťou a tepelnou stálosťou sú vefmi nákladné a predražujú výrobu farebných výrobkov.Pie dyeing of polymers in mass according to MS. 09 245 095 and MS. No. 245,098 dye pigments are used in suitable carriers. The requirement is a high thermal stability of the color pigments, since these are added to the polymer melt, the temperature of which exceeds 300 ° C during homogenization and further processing into molded articles, particularly synthetic fibers. Organic pigments with good dispersibility and thermal stability are very expensive and make the manufacture of colored products more expensive.
Laky monoazopigmentov s obsahom stroncia dávajú vysoko brilantně vyfarbenie a ich použitie do náročnějších výrobkov ako sú vlákna, sa javí ekonomicky vefmi výhodné. Najváčšou zábranou pre toto použitie je ich značná citlivost’ voči teplotám, prejavujúca sa změnou farebného odtieňa. Vo váčšine prípadov ide o teploty vyššie ako 220 °C, pri ktorých sa polyrnéry spracovávajú. Pretože proces farbenia prebieha na hranici použitefnosti týchto lakov, dochádza v dósledku ich degradácie ku změnám alebo kolísaniu farebného odtieňa. Čiastočne sa tento úkaz zmierni použitím vhodného dispergačného systému, ktorý pozostáva derivátov polyalkylénglykolov, ako napr. polypropylénglykolov, zvlášť za přídavku stabilizátorov na báze organických fosfitov.Strontium-containing monoazopigment lacquers give highly brilliant dyeing and their use in more demanding products such as fibers appears to be economically advantageous. The biggest barrier to this use is their high sensitivity to temperatures, resulting in a change in color. In most cases the temperatures are higher than 220 ° C at which the polymers are processed. Since the dyeing process takes place at the limit of applicability of these paints, the color shade or changes due to their degradation. In part, this phenomenon is attenuated by the use of a suitable dispersing system consisting of derivatives of polyalkylene glycols such as polypropylene glycols, in particular with the addition of organic phosphite-based stabilizers.
Uvedené nedostatky bránili použiť ekonomicky výhodné laky monoazopigmentov pri farbení polymérov, najmá pre výrobu vlákien v hmotě.The aforementioned drawbacks prevented the use of economically advantageous monoazopment paints in the dyeing of polymers, especially for the production of fibers in the mass.
Zistili sme, že tento nedostatok lakov monoazopigmentov sa dá úspěšně zredukovať a hranicu použitefnosti týchto posunúť o 20 až 30 °C smerom k vyšším teplotám, čo sa urobí podfa tohoto vynálezu tak, že pri zapracovávaní lakov monoazopigmentov do polyméru sa pridajú soli zinku alebo horčíka, hlavně vo iorme s dobrou afinitou k farbenému polyméru, ako je napr. sof mastných kyselin v množstve 0,1 ažWe have found that this lack of monoazopigment lacquers can be successfully reduced and the usability limit of these monoazopigments reduced by 20 to 30 ° C towards higher temperatures, which is done according to the present invention by adding zinc or magnesium salts to the monoazopigment lacquers. mainly in the moderate affinity for the dyed polymer, such as the fatty acid salt of 0.1 to
