Изобретение относитс к регенерации резин на основе бутилкаучука, вулканизованного смолами.This invention relates to the regeneration of butyl rubber-based rubber, a vulcanized resin.
Известны способы регенерации резин на основе бутилкаучука с использованием в качестве активаторов галогенсодержащих кетонов и ароматических соединений.Known methods for the regeneration of rubber based on butyl rubber using halogen-containing ketones and aromatic compounds as activators.
Недостатком применени данных активаторов вл ютс невысокие физико-механические показатели получаемого регенерата.The disadvantage of using these activators is the low physicomechanical characteristics of the resulting regenerate.
Цель изобретени - использование в качестве активатора дл регенерации резин на основе бутилкаучука М-фенил-М-изопропил-п.фенилепдиамина , обеспечивающего повышение физико-механических и пласто-эластических показателей регенерата.The purpose of the invention is to use as an activator for the regeneration of rubber based on the butyl rubber M-phenyl-M-isopropyl-p. Phenylenediamine, which improves the physico-mechanical and plasto-elastic parameters of the regenerate.
Способ заключаетс в следующем. К ЮО вес. ч. отработанной или бракованной резины на основе бутилкаучука, вулканизированного смолами, предварительно раздробленной на дробильных вальцах добавл ют 2-4 вес. ч. М-фепил-Ы-изоиропил-п-фенилендиамина.The method is as follows. To Yuo weight. Part of waste or rejected rubber based on butyl rubber, vulcanized with resins, previously crushed on the crushing rolls, add 2-4 weight. h. M-phenyl-N-isoyl propyl-p-phenylenediamine.
Смесь нагревают в воздушной среде при 120-140°С в течение 2-3 час, после чего дерулканизат обрабатывают на гладких вальцах .The mixture is heated in air at 120-140 ° C for 2-3 hours, after which the devulcanate is treated on smooth rollers.
Пример. Резиновую диафрагму, использовавшуюс при вулканизации шин разрезают на куски. Куски пропускают через вальцы с рифленой поверхностью валков. Образующуюс при этом щерщавую дробленую шкурку весом 10 кг пропускают несколько раз через гладкие вальцы, где добавл ют 300 г N-фенил - N-изопропил - п - фенилендиамина. Полученную в виде листа смесь помещают вExample. The rubber diaphragm used to vulcanize tires is cut into pieces. Pieces are passed through rollers with a grooved roll surface. The resulting crushed crushed pelt weighing 10 kg is passed several times through smooth rollers, where 300 g of N-phenyl-N-isopropyl-p-phenylenediamine are added. The mixture obtained in the form of a sheet is placed in
сушильный шкаф, где выдерживают при 135°С в течение 2,5 час.drying oven, where it is maintained at 135 ° C for 2.5 hours.
После прогрева девулканизат обрабатывают на гладких вальцах до получени ровногоAfter heating, the devulcanizate is processed on smooth rollers until an even
блест щего полотна.shiny canvas.
Дл определени физико-механических показателей регенерата на лабораторных вальцах готов т смесь следующего состава (вес. ч.): регенерат - 100,0; белила цинковые-5 ,0; тиурам-1,0; каптакс-0,5; сера- 2,0; режим вулканизации составл ет 30 мин при 160°С.To determine the physico-mechanical parameters of the regenerate, a mixture of the following composition (weight h) is prepared on laboratory rolls: regenerate - 100.0; zinc white-5, 0; thiuram-1.0; captax-0.5; sulfur - 2.0; vulcanization is 30 minutes at 160 ° C.
Свойства полученного регенерата в сравнеНИИ с регенератом известного способа привод тс в таблице.The properties of the obtained regenerate in comparison with the regenerate of a known method are listed in the table.
Предмет изобретени Subject invention
Способ регенерации резин на основе бутилкаучука , вулканизованного смолами, в присутствии активатора, отличающийс тем, что, с целью улучшени свойств регенерата, в качестве активатора используетс Ы-фенил-Ыизопропил-п-фенилендиамин .A method of regenerating rubber based on butyl rubber, vulcanized with resins, in the presence of an activator, characterized in that, in order to improve the properties of the regenerate, L-phenyl-Yisopropyl-p-phenylenediamine is used as an activator.

Methods are known to regenerate vulcanized butyl rubber using activators, for example, alkylphenol disulfide, halogen-containing patterns, and body patterns and aromatics and aromatics with the use of activators; as well as improving the quality of the regenerate, it is proposed to use as an activator in the regeneration of butyl rubber, vulcanized with resins, diphenylguanium Din. The method consists in the following. To 100 weight. Part of waste or rejected rubber based on butyl rubber, vulcanized with resins, previously crushed on the crushing rollers, add 2-4 weight. including activator of destruction - diphenylguanidine known method. The mixture is heated in an air or vapor-air environment at a temperature of 160-180 ° C for 2-3 hours. After heating, the devulcanized product is subjected to additional mechanical treatment to homogenize and purify the impurities and part of the slightly devulcanised rubber. Example. The butyl rubber rubber diaphragm used in the vulcanization of tires is cut into pieces and passed through rollers with a grooved roll surface. The resulting sheet is placed in a laboratory autoclave, where it is kept at 180 ° C for 2 hours. After heating, the devulcanate is processed on smooth rollers until an even gloss is obtained.
