Abstract:
Disclosed herein is a method for manufacturing a high temperature resistant sound absorbing material for vehicles. In particular, the method includes a beating/blending step, a web forming step, a web laminating step, a needle punching step, a first binder soaking step, a first solvent recovering step, a second binder soaking step, a second solvent recovering step, a second binder surface treating step, a second solvent recovering step, and a molding step. Further, the method of the present invention may include a first binder surface treating step, a first surface solvent recovering step, and a molding step after the first solvent recovering step. In addition, the method of the present invention may further include a third binder soaking step, a third solvent recovering step, a third binder surface treating step, a third surface solvent recovering step, and a molding step after a nonwoven fabric is formed in the needle punching step.
