Изобретение касаетс  получени  резин на основе хлорсульфированного полиэтилена (ХСПЭ).The invention relates to the preparation of rubber based on chlorosulfonated polyethylene (HSPE).

Известна вулканизуема  композици  на основе ХСПЭ, в которой в качестве вулканизующего агента применена комбинаци  органической кислоты и окислов металлов: свинца и магни . Однако использование окислов металлов в дозировке 20-40 вес. ч. приводит к резкому увеличению удельного веса; кроме того, окись свинца весьма токсична. Необходимо также отметить, что наполненные смеси на основе ХСПЭ весьма жестки, добавление обычных пластификаторов ухудшает показатели вулканизатов.A curable CSPA-based composition is known, in which a combination of an organic acid and metal oxides: lead and magnesium is used as a vulcanizing agent. However, the use of metal oxides in the dosage of 20-40 weight. h. leads to a sharp increase in specific gravity; in addition, lead oxide is very toxic. It should also be noted that the filled mixtures based on CSPA are very tough; the addition of conventional plasticizers worsens the values of the vulcanizates.

Предлагаетс  вулканизуема  композици , лишенна  этих недостатков. В качестве агента вулканизации в такой композиции применены олигоэфиракрилаты (ОЭА) в дозировке 10-40 вес. ч., предпочтительно 20,0 вес. ч., в дополнение к обычно примен емым окислам металлов.A vulcanizable composition is proposed that is free from these disadvantages. As a vulcanization agent in such a composition, oligoester acrylates (OEA) are used in a dosage of 10-40 wt. hours, preferably 20.0 weight. hours, in addition to the commonly used metal oxides.

Введение ОЭА позвол ет уменьшить дозировку окисла металла, существенно повышает сопротивление раздиру вулканизатов, резко уменьшает в зкость невулканизованных смесей .The introduction of OEA can reduce the dosage of metal oxide, significantly increases the tear resistance of vulcanizates, drastically reduces the viscosity of unvulcanized mixtures.

Добавление к ХСПЭ олигоэфиракрплатов дает качественно новый эффект-возможность вулканизации и полимеризации олигоэфиракрилатов в отсутствие доноров свободных радикалов: альтакса, перекисей и тому подобных соединений.Addition of oligoether embryo to CSPE gives a qualitatively new effect — the possibility of vulcanization and polymerization of oligoether acrylates in the absence of free radical donors: altax, peroxides, and similar compounds.

Пример. Готов т смеси, включающие ХСПЭ, канифоль, стеариновую кислоту, каптакс , окись магни , окись свинца, олигоэфиракрилат (ОЭА),со-метакрил-(бистриэтиленгликоль )-фталат, сажу ПМ-75, дибутилфталат . Смеси готов т на вальцах при температуре 30-40°С. Врем  выдержки смеси до вулканизации 12 час. Вулканизацию пластинок толщиной 2 мм осуществл ют при 160°С в течение 20 мин.Example. Mixtures are prepared that include HSPE, rosin, stearic acid, captax, magnesium oxide, lead oxide, oligoester acrylate (EAE), co-methacryl- (bistriethylene glycol) -phthalate, carbon black PM-75, dibutyl phthalate. Mixtures are prepared on rollers at a temperature of 30-40 ° C. The dwell time of the mixture before vulcanization is 12 hours. Vulcanization of 2 mm thick plates was carried out at 160 ° C for 20 minutes.

Состав смесей приведен в табл. 1, свойства резиновых вулканизатов - в табл. 2.The composition of the mixtures are given in table. 1, the properties of rubber vulcanizates - in table. 2
