摘要：The present invention relates to a method for manufacturing a highly heat-resistant sound absorbing and screening material, and more specifically comprising: a rear surface fiber-mixing step; a web forming step; a web stacking step; a needle punching step; a binder impregnating step; and a solvent recovering step. The highly heat-resistant sound absorbing and screening material manufactured according to the present invention is installed on an area closest to the source of noise from an engine and an exhaust system to reduce radiated noise from the engine and the exhaust system, thereby improving quietness inside a vehicle, and is applied to areas surrounding metal parts that are hotter than 200℃ thereby performing a heat-shielding function to protect plastic and rubber parts.
