Изобретение относитс к композици м на основе силоксановых к.аучуков, а именно к ненаполненным композици м на основе полиСтиролсилоксанового каучука, вулканизаты на основе которых используют в качестве материала эластичных копировальных форм, примен емых дл тиражировани различных технических деталей и художественных изделий в протезировании, производстве печатных тампонов и валиков.SUBSTANCE: invention relates to compositions based on siloxane rubber materials, namely to unfilled polystyrene siloxane rubber based compositions, vulcanizates based on which are used as a material of elastic copy forms used for the reproduction of various technical details and artistic products in prosthetics, printing tampons and rollers.
Известна композици 1 на основе полистиролсилоксанового каучука, тетразтоксисилана, диэтилдикаприлата олова и олигометилсилоксана формулы (КСНз)э8Юо5И8Ю2 }„ где п ь .6-10, вз тых ,в соотношении, мас.ч.: Полистиролсилоксановый каучук100The known composition 1 is based on polystyrene siloxane rubber, tetrazoxy silane, diethyl dicicaprylate tin and oligomethyl siloxane of the formula (HCH) e8Hyo5H8J2} where pb. 6-10, taken, in a ratio, parts by weight: Polystyrene siloxane rubber100

Недостаток известной композиции состоит в том, что вулканизаты иа ее основе быстро тер ют эластичность.A disadvantage of the known composition is that the vulcanizates and its base quickly lose their elasticity.
Целью изобретени вл етс стабилизаци эластических свгаств вулканизатов на основе композиции, содержащей указанные выше компонентььThe aim of the invention is to stabilize the elastic properties of vulcanizates based on a composition containing the above components.
Цель достигаетс тем, что композици на основе полистиролсилоксанового каучука, теч азтоксисилаиа, диэт лдикалрилата олова, олигометилсилоксана формулы (СНз)з8|Оо51 IStOjjJ j,e n - 6-10, дополнительно содержит оксид цинка или кадми в смеси The goal is achieved in that a composition based on polystyrene siloxane rubber, ate aztoxysilane, tin diethyl dicrylate, oligomethylsiloxane of formula (CH3) s8 | Oo51 IStOjjJ j, e n - 6-10, additionally contains zinc oxide or cadmium in a mixture

Изготовление композиции и ее дезаэрацию ооушествл ют в вакуум-смесителе.The preparation of the composition and its deaeration are taken up in a vacuum mixer.
Исходную в зкость композици определ ют на рео-вискозиметре по методу Гепплера, жизнеспособность оценивают по ТУ 6-02-80573 .The initial viscosity of the composition is determined on a regio-viscometer according to the method of Goppler, viability is assessed according to TU 6-02-80573.
Вулканизацию провод т при комнатной температуре . Физнко-механические показатели определ ют по ГОСТ 270-64.The vulcanization is carried out at room temperature. Physical-mechanical parameters are determined according to GOST 270-64.
Составы известной 1 и предлагаемыхThe compositions known 1 and proposed
композиций даны в табл. I.compositions are given in table. I.
Свойства композиций вулканизатов на их основе даны в табл. 2.The properties of the compositions of vulcanizates based on them are given in table. 2
Из приведенных данных видно, что наиболь шей стабильностью относительного удлинени при хранении обладают вулканизаты на основе композиций, содержащих оксиды цинка или кадми , титана или циркони в количестве и соотношении, указанном выше.It can be seen from the above data that vulcanizates based on compositions containing oxides of zinc or cadmium, titanium or zirconium in the amount and ratio indicated above have the highest stability of the relative elongation during storage.
Таким , предлагаема композици позвол ет существенно повысить стабильность эластических свойств вулканизатов на ее основе по сравнению с вулканизатами на основе, известней композиции, при этом остальньк физико-механические показатели вулканизатов сохран ютс .Thus, the proposed composition makes it possible to significantly increase the stability of the elastic properties of vulcanizates based on it compared to vulcanizates based on the known composition, while the remaining physical and mechanical properties of the vulcanizates are preserved.
