VIBRATION-DAMPING MATERIAL

摘要

PURPOSE:To obtain the title material small in Young's modulus change with temperature, excellent in damping characteristics by incorporating a filler in a blend comprising natural rubber etc., specific nylon fiber and acrylonitrile- butadiene rubber at specified proportion followed by curing. CONSTITUTION:The objective material can be obtained by curing a composition prepared by incorporating a filter in a blend comprising (A) 40-90wt.% of natural or chloroprene rubber, (B) 5-30wt.% of a natural rubber-grafted nylon fiber and (C) 5-30wt.% of an acrylonitrile-butadiene rubber 10-30wt.% in acrylonitrile content.
