Description

SOS прогревают в воздушном термостате в течение 120 мин при температуре loo С и охлаждают до комнатной температуры. Охлажденную смесьпорошков , обладающую хорошей сыпучестью , ввод т в каучук (смешанный предварительно с те сническим углероgoM и стеарином) на вальцах соглас режиму ГОСТа 15627-70.SOS is heated in an air thermostat for 120 minutes at a temperature of loo C and cooled to room temperature. The cooled mixture of powders, which has good flowability, is introduced into rubber (pre-mixed with tego-carbon and stearin) on the rollers according to GOST 15627-70.

Из табл.1 видно, что .рптимальное врем  вулканизации смеси, полученной по предлагаемому способу, составл ет 33-40 мин в отличие от 80. мин дл  смеси,, полученной по известному способу. По физико-механическим свойствам вулканизаты смеси, полученной по предлагаемому способу не уступсиот вулканиэатам смеси, полученной по известному способу. Эффект сокращени  времени вулканизации обусловлен именно совмес гньм прогревом вулканизующих агентов. Эведение в каучук ингредиентов вулканизующей группы, по отдельности .прогретых (100С, 120 мин), охлажденных и смешанньах после охлаждени  в порошкообразном состо нии (резинова  смесь 3), не приводит к уменьшению продолжительности вулканизации .From Table 1 it can be seen that the optimal time for vulcanization of the mixture obtained by the proposed method is 33-40 minutes, as opposed to 80 minutes for the mixture obtained by a known method. On the physicomechanical properties of the vulcanizates of the mixture obtained by the proposed method is not a cessation of the mixture obtained by a known method. The effect of reducing the time of vulcanization is due precisely to the combined warming up of vulcanizing agents. The introduction into rubber of the ingredients of the vulcanizing group, individually heated (100 ° C, 120 min), cooled and mixed after cooling in a powdery state (rubber mixture 3), does not lead to a decrease in the duration of vulcanization.

П р и м е р 2. Готов т резиновую смесь на основе СКМС-ЗОАРК по примеру 1. Варианты.смесей 1,2 и 3 аналогичны примеру 1.PRI mme R 2. Preparing a rubber mixture based on SKMS-ZOARK according to example 1. Options for mixtures 1, 2 and 3 are similar to example 1.

Из сопоставлени  физико-механических показателей резин, что представлено в табл 2, видно, что оптимальное врем  вулканизации смеси, полученной по известному способу, состава ет 80 мин. В случае смеси,, полученной по предлагаемому способу., оно сокращаетс  до 30-40 мин без ухудшени  физико-механических свойств вулканизатов , ;ТВведение в каучук ингредиентов вулканизующей группы, по : 2 отдельности прогретых (, 100 мин) и смешанных после охлаждени  в порошкообразном состо нии (резинова  смесь 3), не приводит к уменьшению продолжительности вулканизации.From a comparison of the physicomechanical parameters of rubbers, which are presented in Table 2, it can be seen that the optimal time for vulcanization of the mixture obtained by a known method is 80 minutes. In the case of a mixture obtained by the proposed method, it is reduced to 30-40 minutes without deteriorating the physical and mechanical properties of the vulcanizates; TREATION into rubber of the vulcanizing group, in: 2 separate heated (, 100 minutes) and mixed after cooling in a powdered state (rubber mixture 3), does not reduce the duration of vulcanization.

Таким образом, использование предлагаемого способа получени  резиновой смеси, вулканизуемой серой и ускорител ми в присутствии активаторов, дает возможность сократить длительность вулканизации резиновой смеси и тем самьм интенсифицировать процесс вулканизации резиновых изделий, увеличить производительность вулканизационного оборудовани .Thus, the use of the proposed method for obtaining a rubber mixture, vulcanized by sulfur and accelerators in the presence of activators, makes it possible to reduce the duration of vulcanization of the rubber mixture and thereby intensify the process of vulcanization of rubber products, to increase the productivity of vulcanization equipment.
