POLYAMIDE RESIN COMPOSITES FOR SOUND INSULATION

摘要

The present invention relates to a polyamide resin composition for sound insulation. The polyamide resin composition for sound insulation comprises: polyamide 66 or polyamide 6 resin; glass fibers for improving the mechanical properties and heat-resistant properties of the composition; barium sulfate for improving the sound insulation of the composition; an antioxidant for preventing the deterioration of the composition; a heat-resistant stabilizer for improving heat resistance; and a lubricant for improving moldability by reducing friction. Therefore, the polyamide resin composition for sound insulation has excellent mechanical properties, heat-resistance properties, noise vibration blocking performance, injection-moldability, etc., can be made lighter and can realize a complex shape.
