Изобретение относитс к резиновой промышленности, в частности, к герметику на основе бутилкаучука.This invention relates to the rubber industry, in particular, to butyl rubber based sealants.
Известен герметик на основе бутилкаучука , включающий индустриальное масло и наполнитель, например в соотношении 5:25:70 (мас.%) 1.Known sealant based on butyl rubber, including industrial oil and filler, for example in the ratio of 5:25:70 (wt.%) 1.
Данный герметик имеет высокие паро проницаемость и в зкость. Кроме того, он Не стоек к агрессивным средам.This sealant has high vapor permeability and viscosity. In addition, it is not resistant to aggressive environments.
Цель изобретени состоит в снижении паропроницаемостн и повышении стойкости к агрессивным средам при одновременном снижении в зкости герметика.The purpose of the invention is to reduce vapor permeability and increase resistance to aggressive media while reducing the viscosity of the sealant.
Поставлейна цель достигаетс тем, что герметик на основе бутилкаучука, включающий индустриальное масло и наполнитель , дополнительно содержит дивинилпипериленовый низкомолекул рный каучук и битум при следующем соотношении компонентов, мас.%:The objective is achieved in that the sealant based on butyl rubber, including industrial oil and filler, additionally contains divinyl-piperylene low molecular weight rubber and bitumen in the following ratio, wt.%:
