A method for producing a sound insulating plates part having an excellent sound absorption power and sound insulating boards part, which is produced by the same

摘要

A method for producing a sound insulating plates part with an improved sound absorption power is disclosed. The sound insulating boards part, using, as a material, a recycled sound-absorbing material, the polyurethane foam with an excellent sound absorption power and impact resilience, during the press moulding; and by producing a sound absorption part on the rear surface of the sound insulating plates part produced by a deformation properties - processing method. In addition, it is also a manufactured by the method, sound insulating boards part discloses. Consequently, the sound absorption power of the sound insulating plates, partially around about 20% or more can be improved, the manufacturing costs of the same, by means of recycled resources with the use of waste layers and the manufacturing process can be reduced in comparison to the related art is to be simplified.
