<p>PROBLEM TO BE SOLVED: To provide a sound-absorbing member using rubber chips in which waste tires are used and which can be manufactured easily at a low cost and further, displays high sound-absorbing effects stably even when it is thin, and provide also a manufacturing method thereof. SOLUTION: Rubber chips 4, 5 obtained by crushing waste tires are laminated by each specified thickness by changing the grain size. The rubber chips 4, 5 are laminated by each specified thickness from great grain size to small. The rubber chips 4, 5 are laminated in each-specified thickness while being bonded, solidified by vulcanization instead of by adhesion and further, the rubber chip material is mixed with an adhesive and a colorant as required to be laminated in such a manner that the grain size varies. The rubber chip material is laminated without adding the adhesive and is poured into a form and then vulcanized and dried.</p> |
