Description
Изобретение относитс к термопластичным материалам, которые могут быть использованы дл изготовлени различных изделий, например шин, гибких труб, прокладок и формованных изделий.
Целью изобретени вл етс улучшение ударной в зкости материала.
Термопластичный материал получают путем приготовлени смеси диенового каучука, полиолефиновой смолы и вулканизующих веществ с последующим перемешиванием смеси при температуре вупканиэации до завершени вулканизации в смесителе Бенбери, смесителе Брабендера или в смесительных шприцмашинах . Предпочтительный диапазон температуры вулканизации составл ет 180-200ЙС.
Одним из вариантов получени термопластичного материала согласно изобретению вл етс предварительна вулканизаци каучука в отсутствии смолы динамическим способом с последующим его измельчением до порошкообразного состо ни и смешиванием с полиолефиновой смолой при температуре выше температуры плавлени или разм гчени смолы.
При этом используют диеновый вулканизованный каучук с размером частиц не больше чем 50 мкм в количестве мае.ч. и термопластичную поли- олефиновую смолу в количестве 30- 4 5 ма с. ч.
В качестве термопластичной поли- олефиновой матрицы используют полиэтилен или полипропилен.
В качестве вулканизованного диенового каучука используют каучук, выбранный из группы, состо щей из полибутадиенового каучука, натурального или синтетического полиизопрено- вого каучука и сополимерного каучука на основе диена со стиролом, винил- пиридином, акрилонитрилом или мета- крилонитрилом.
В табл. 1 приведены показатели термопластичного материала, содержащего полиолефиновую смолу и натураль- ный каучук.
В табл. 2 приведены показатели термопластичного материала, содержащего полиолефиновую смолу и стирол- бутадиеновый каучук.
В табл. 3 приведены показатели термопластичного материала, содержащего полипропилен и полибутадиеновый каучук.
В табл. Ь приведены показатели термопластичного материала, содержащего полибутадиеновый каучук и полипропилен , с использованием серу-со- держащей вулканизующей системы.
В табл. 5 приведены показатели термопластичного материала, содержащего нитриловый каучук и полиэтилен.
