Изобретение относитс  к области получени  резиновых смесей.The invention relates to the field of rubber compounds.

Известна резинова  смесь на основе бутадиен-нитрильного каучука, включаюнда  в качестве пластификаторов сложные эфиры, которые повышают иластоэластические свойства сырых резиновых смесей, а также морозостойкость вулканизатов. Однако это приводит к замедлению вулканизации, значительному увеличению относительного и остаточного удлинени .A rubber compound based on butadiene-nitrile rubber is known, including esters as plasticizers, which increase the elastic plastic properties of raw rubber compounds, as well as the frost resistance of vulcanizates. However, this leads to a slower vulcanization, a significant increase in relative and residual elongation.

Предлагаема  резинова  смесь позвол ет получать на основе бутадиен-нитри.1ьных каучуков резины, лишенные этих недостатков.The proposed rubber compound allows to obtain, based on butadiene nitrile rubber rubbers, free from these disadvantages.

Сущность изобретени  заключаетс  в том, что в качестве пластификатора используют динитрилы двухосновных кислот, например адипонитрнл, глутаронитрил в сочетании с небольшим количеством перекиси марганца.The essence of the invention is that dinitriles of dibasic acids, for example adiponitrnl, glutaronitrile in combination with a small amount of manganese peroxide, are used as a plasticizer.

Предлагаемый пластификатор устойчив, применение его не вносит никаких изменений в технологию производства.The proposed plasticizer is stable, its application does not make any changes in the production technology.

Приведенные в табл. 1 н 2 данные показывают , что получаемые при вулканизаты сочетают все ценные свойства, врем  вулканнзации значительно сокращаетс , повышаетс  морозостойкость по сравнению с известными .Given in Table. 1 n 2 data show that the obtained vulcanizates combine all valuable properties, the vulcanization time is significantly reduced, the frost resistance is increased in comparison with the known ones.
