Highly lubricative sound absorbing material and cable reel including the same

摘要

A highly lubricative sound-absorbing material is produced inexpensively and attenuates sliding noise and vibration noise. The highly lubricative sound-absorbing material comprises a rubber sheet (21) and a highly lubricative coating layer (22) formed directly on a surface of the rubber sheet by coating the surface with a mixture of an adhesive and a fluororesin system coating agent such as an polytetrafluoroethylene resin or the like by a thickness of 1 to 10 mu m. The rubber sheet (21) is formed into an annular shape and coated on its surface with the highly lubricative sound-absorbing layer (22) having a thickness of 1 to 10 mu m, preferably 3 mu m. The rubber sheet (21) is attached to a surface of a cable reel on which a flat cable slides.
