VIBRATION-DAMPING MATERIAL

摘要

PURPOSE:To obtain a vibration-damping material decreased in a temperature shift and improved in vibration-damping properties by mixing a resin based on a room temperature curing liquid epoxy resin with mica and chopped glass strands. CONSTITUTION:A vibration-damping material prepared by mixing a resin based on a room temperature curing liquid epoxy resin with mica and chopped glass strands. An example of the resin used is a mixture comprising a room temperature curing liquid epoxy resin such as bisphenol A epoxy resin or bisphenol F epoxy resin, a polyamideamine and a polyamine. The mixing ratio of the resin to mica and chopped glass strands is desirably such that 25-200 pts.wt. total of mica and chopped glass strands is used per 100 pts.wt. resin.
