Description

Vynález sa týká spósobu neprášivej úpravy gumárenského urýchlovača na báze N-cyklohexyl-2-benztiazolyl sulfénamidu pomocou hydrogenačne rafinovaného oleja.The present invention relates to a process for the non-dusting treatment of a rubber accelerator based on N-cyclohexyl-2-benzothiazolyl sulfenamide with hydrogenated oil.

Gumárenský urýchlovač na báze N-cyklohexyl-2-benztiazolyl sulfénamidu sa vyrába niekolkonásóbnou filtráciou z jeho vodnej suspenzie, pričom filtračný koláč sa dalej spracováva v granulačnej sústave, pozostávajúcej z kompaktora a dezintegrátora. Po oddělení prachového podielu sa vlhký granulát suší.The rubber accelerator based on N-cyclohexyl-2-benzothiazolyl sulfenamide is produced by multi-step filtration from its aqueous suspension, the filter cake being further processed in a granulation system consisting of a compactor and a disintegrator. After separation of the dust fraction, the wet granulate is dried.

Nevýhoda tohoto urýchlovača spočívá v tom, že pri granulácii vzniká značný prachový podiel. Počas sušenia dochádza tiež k stratám materiálu v dósledku únosu sušiacim vzduchom. Zvyšok prachu prechádza do hotového produktu a spósobuje ekologické aj technologické problémy pri dalšom spracovaní hotového výrobku.The disadvantage of this accelerator is that a considerable dust fraction is generated during granulation. During drying, the material is also lost as a result of air drying. The rest of the dust passes into the finished product and causes environmental and technological problems in the further processing of the finished product.

Uvedený nedostatok rieši spósob úpravy gumárenského urýchlovača na báze N-cyklohexyl-2-benztiazoly1 sulfénamidu podlá vynálezu, ktorého podstata spočívá v tom, že k vodnej suspenzi N-cyklohexyl-2-benztiazolyl sulfénamidu a/alebo k jej filtračnému koláčů získanému po přefiltrovaní tejto suspenzie sa přidá hydrogenačne rafinovaný olej o hustotě najmenej 865 kg/m^, o bode vzplanutia najjnenej 212 °C, o bode tuhnutia najviac -12 °C, o kinematickej viskozitě pri 50 °C 26 až 36 mm^/s, o viskozitnom indexe najmenej 90, vo formě hmly. Filtračný koláč sa potom vysuš! a zgranuluje.This problem is solved by a process for treating a rubber accelerator based on N-cyclohexyl-2-benzothiazolyl sulfenamide according to the invention, which consists in that the aqueous suspension of N-cyclohexyl-2-benzothiazolyl sulfenamide and / or its filtercakes obtained after filtering the suspension Add hydrotreated oil of a density not less than 865 kg / m ^, a flash point not less than 212 ° C, a freezing point not more than -12 ° C, a kinematic viscosity at 50 ° C of 26 to 36 mm ^ / s, a viscosity index of at least 90, in the form of a mist. The filter cake is then dried! and granulated.

Nový a vyšší účinok takejto úpravy gumárenského urýchlovača spočívá v tom, že hydrogenačne rafinovaný olej přidaný do suspenzie, alebo na povrch filtračného koláča zvyšuje kompaktnost a celistvost produktu lisovaného v granulačnej sústave, znižuje tak vznik prachového podielu počas granulácie a zlepšuje spracovatelské vlastnosti hotového výrobku.A new and higher effect of such treatment of the rubber accelerator is that the hydrotreated oil added to the slurry or to the surface of the filter cake increases the compactness and integrity of the product pressed in the granulation system, thus reducing the formation of dust during granulation and improving the processing properties of the finished product.

Spósob neprášivej úpravy gumárenského urýchlovača na báze N-cyklohexyl-2-benztiazolyl sulfénamidu podlá vynálezu možno vysvětlit na nasledovných príkladoch.The non-dusting treatment of the N-cyclohexyl-2-benzothiazolyl sulfenamide rubber accelerator according to the invention can be explained by the following examples.

Přiklad 1Example 1

Vodná suspenzia N-cyklohexyl-2-benztiazolyl sulfénamidu sa kontinuálně privádza na povrch rotačného bubnového filtra. Na povrch filtračného koláča sa kontinuálně nanáša v hmotnostnom pomere 1% až 3% vzhl‘adom na sušinu hydrogenačne rafinovaný olej rozptýlený na hmlu. Filtračný koláč sa zrezáva, suši a granuluje.The aqueous suspension of N-cyclohexyl-2-benzothiazolyl sulfenamide is continuously fed to the surface of a rotary drum filter. A hydrotreated oil dispersed in the mist is continuously applied to the surface of the filter cake in a weight ratio of 1% to 3% based on dry matter. The filter cake is trimmed, dried and granulated.

Příklad 2Example 2

Do prietokovej nádoby sa kontinuálně přidává vodná suspenzia N-cyklohexyl-2-benztiazolyl sulfénamidu a za miešania sa kontinuálně přidává v hmotnostnom pomere 1% až 3% vzhladom na sušinu hydrogenačne rafinovaný olej rozptýlený na hmlu. Suspenzia sa dalej kontinuálně filtruje, filtračný koláč sa zrezáva, suší a granuluje.An aqueous suspension of N-cyclohexyl-2-benzothiazolyl sulfenamide is continuously added to the flow vessel and 1 to 3% by weight of the hydrotreated oil dispersed in the mist is continuously added under stirring. The suspension is further continuously filtered, the filter cake is trimmed, dried and granulated.

Příklad 3Example 3

Prvý podiel hydrogenačne rafinovaného oleja sa přidává do vaničky kontinuálneho bubnového rotačného filtra, do ktorej sa kontinuálně privádza vodná suspenzia N-oyklohexyl-2-benztiazolyl sulfénamidu, druhý podiel hydrogenačne rafinovaného oleja sa přidává na povrch tohoto filtra vo formě hmly, pričom úhrnný podiel oleja je 1% až 3% vzhladom na sušinu. Filtračný koláč sa zrezáva, suši a granuluje.The first portion of hydrotreated oil is added to the tray of a continuous drum rotary filter to which an aqueous suspension of N-cyclohexyl-2-benzothiazolyl sulfenamide is continuously fed, the second portion of hydrotreated oil is added to the filter surface as a mist, the total oil being 1% to 3% by dry weight. The filter cake is trimmed, dried and granulated.

Vynález možno využiť pri výrobě gumárenského urýchlovača na báze N-cyklohexyl-2-benztiazolyl sulfénamidu.The invention can be used in the manufacture of a rubber accelerator based on N-cyclohexyl-2-benzothiazolyl sulfenamide.
