Abstract

PURPOSE: To provide the titled compsn. which has excellent soundproofness and does not cause any problems on metal corrosion, by kneading a powdered lead compd. having a specified specific gravity together with a plastic or a rubber.
CONSTITUTION: 200W1,800pts.wt. powdered lead compd. having a specific gravity of 5 or above such as lead monoxide and, if necessary, an inorg. filler, a flame retarder, a plasticizer, a stabilizer, a colorant, an antioxidant, etc. are blended with 100pts.wt. plastic or rubber such as PE or silicone rubber. The mixture is kneaded.
EFFECT: The compsn. damps vibration-generating source, and absorbs vibration to impart a noise-inhibiting effect.
