Description
В резиновой промышленности известно большое количество различных органических соединений, вл ющихс ускорител ми процесса вулканизации резиновых смесей. Особенностью описываемого способа вулканизации резиновых смесей на основе натурального и синтетического каучуков вл етс то, что, с целью расширени ассортимента ускорителей и пол чени высококачественных вулканизатов, примен ют органический ускоритель типа 1,4-пиперазин-бис-карботиосульфен-диалкила/мидов , получаемых взаимодействием сероуглерода с пиперазином в щелочной среде с последующей окислительной конденсацией продукта реакции с соответств ющими вторичными алифатическими аминами.In the rubber industry, a large number of various organic compounds are known, which are accelerators of the process of vulcanization of rubber compounds. A specific feature of the described method of vulcanization of rubber mixtures based on natural and synthetic rubbers is that, in order to expand the range of accelerators and to obtain high-quality vulcanizates, an organic accelerator of the type 1.4-piperazine-bis-carbothiosulfene-dialkyl / amide, obtained by the interaction carbon disulfide with piperazine in an alkaline medium, followed by oxidative condensation of the reaction product with the corresponding secondary aliphatic amines.
Применение эквимолекул рных (по отношению к обычно примен емому каптаксу) количеств 1,4-пиперазин-бис-карботиосульфендиалкиламида в резиновых смес х на основе натурального каучука приводит к получению вулканизатов, по значению модул в 2,5 раза превышающие вулканизаты с каптаксом и характеризующиес также более высоким сопротивлением разрыву.The use of equimolecular (with respect to the commonly used captax) quantities of 1,4-piperazine-bis-carbothiosulfene alkylamide in rubber mixtures based on natural rubber results in vulcanizates, by a modulus value 2.5 times greater than vulcanizates with captax and are also characterized higher tear resistance.
Нар ду с этим предлагаемый ускоритель сочетает высокую вулканизующую активность с отсутствием склонности к преждевременной вулканизации .Along with this, the proposed accelerator combines a high vulcanizing activity with the absence of a tendency to premature vulcanization.
В резиновых смес х на основе бутадиенстирольного каучука ускоритель вулканизации 1,4-ниперазин-бис-карботиосульфендиалкиламид равноценен действию наиболее эффективного, дл данного типа каучука, ускорител сульфенамида БТ.In rubber compounds based on butadiene rubber, the vulcanization accelerator 1,4-nicperazine-bis-carbothiosulfene alkyl amide is equivalent to the effect of the most effective BT sulfenamide accelerator for this type of rubber.
