Изобретение относитс  к вулканизации резин на основе бутадиеннитрильного каучука.This invention relates to the vulcanization of rubbers based on butadiene nitrile rubber.

Известна вулканизуема  резинова  смесь на основе бутадиеннитрильного каучука, содержаща  в качестве вулканизующего агента п тиокись сурьмы.A vulcanizable rubber mixture based on butadiene nitrile rubber, containing antimony pentoxide as a vulcanizing agent, is known.

Указанный вулканизующий агент обеспечивает высокую теплостойкость резин, но замедл ет скорость вулканизации.Said vulcanizing agent provides high heat resistance to rubber, but slows down the rate of vulcanization.

Известна также резинова  смесь на основе бутадиеннитрильного каучука, вулканизуема  фенолформальдегидной смолой.Also known rubber compound based on butadiene nitrile rubber, vulcanizable phenol-formaldehyde resin.

Однако этот вулканизующий агент замедл ет скорость вулканизации, резко повышает модули и снижает относительное удлинение в процессе старени .However, this vulcanizing agent slows down the rate of vulcanization, dramatically increases the moduli and reduces the relative elongation during the aging process.

Использовапие в качестве активаторов при вулканизации фенолформальдегпдной смолой бутадиеннитрильпых резин галоид органических и неорганических активаторов увеличивает скорость вулканизации, но не устран ет перечисленных недостатков.The use of butadiene nitrile rubber as an activator in the vulcanization of phenol-formaldehyde resin with a halide of organic and inorganic activators increases the rate of vulcanization, but does not eliminate these disadvantages.

Совместное применение при вулканизации бутадиеннитрильных резин фенолформальдегидной смолы и п тиокиси сурьмы в количестве 3-10 вес. ч. на 100 вес. ч. каучука обеспечивает высокую скорость вулканизации, повышение сопротивлени  скорчингу смесей и тепловому старени  вулкан 1затов.The combined use of phenol-formaldehyde resin and antimony pentoxide in the vulcanization of butadiene nitrile rubbers in an amount of 3-10 wt. hours per 100 weight. the rubber provides a high cure rate, an increase in the resistance to the scorching of the mixtures and the thermal aging of the volcano of 1sats.
