Abstract

The present invention relates to a method for manufacturing a vehicle sound-absorbing material. The method for manufacturing a vehicle sound-absorbing material, having an adhesive resin layer (20) formed between a surface layer (10) and a sound-absorbing layer (30), comprises: a preparation step (S10) of preparing surface layer fabric (1) and sound-absorbing layer fabric (3) and heating an adhesive thermoplastic resin (5); a step (S20) of supplying the surface layer fabric (1), the sound-absorbing layer fabric (3) and the heated adhesive thermoplastic resin (5) to the gap between an upper roller (R1) and a lower roller (R2), such that the heated adhesive thermoplastic resin (5) is interposed between the surface layer fabric (1) and the sound-absorbing layer fabric (3); and a press-molding step (S30) of forming a sound-absorbing material (100) from the surface layer (10), the sound-absorbing layer (30), and the adhesive resin layer (20) by combining the surface layer fabric (1), the thermoplastic resin (5), and the sound-absorbing layer fabric (3) by pressing using the upper roller (R1) and the lower roller (R2). The outer surface of the upper roller (R1) and/or lower roller (R2) used in the press-molding step (S30) has a protrusion (T). The protrusion (T) presses the exposed surface of the surface layer fabric (1) and/or of the sound-absorbing layer fabric (3), thus enabling the thermoplastic resin (5) to be pressed by the protrusion (T) and bilaterally moved. Thus, the adhesive resin layer (20) in the part pressed by the protrusion (T) is formed so as to be thinner than the part which is not pressed by the protrusion (T). Thus, both sides of the part pressed by the protrusion (T) in the press-molding step (S30) are restored to form a gas passage.

By the way, in the conventional vehicle flooring material, since the separate sound insulating material is bonded to the skin layer and the sound-absorbing layer forming the flooring material using an adhesive or direct coating method, the overall weight of the flooring material is increased to increase fuel economy of the vehicle. In addition, the manufacturing process of the flooring is complicated, there is a problem that the productivity is lowered.

The inventors have invented a vehicle flooring material which can not only reduce noise and vibration, but also simplify the manufacturing process of the flooring material, thereby improving productivity and reducing the weight of the vehicle.
