摘要： The invention relates to a rubber-based soundproofing material. The vulcanised rubber mixture consists of the following components: - a rubber or rubber blend; -a heavy metal and/or its alloys and/or its oxides and/or its salts in powder form, in addition to conventional mixing ingredients. The inventive material is characterised by a rubber mixture based on non-blended chlorobutyl rubber, bromobutyl rubber or acrylate rubber; or nitrile rubber or styrene-butadiene rubber, both of which are blended with epoxidised natural rubber. The rubber mixture has the following proportions: 10-50 wt. % rubber or rubber blend, 85-40 wt. % heavy metal and/or its alloys and/or its oxides and/or its salts, 5-10 wt. % mixing ingredients. The inventive rubber material based on bromobutyl rubber and Fe powder (curves a and b) is compared with sheet metal (curves c and d).
