Prepn of sound-isolaitng damping composite polymer-base metal powder material

The preparation method of macromolecular base metal power sound-proofing vibratio-reducing damping material includes the following steps: using SPVC, DOP, DBP, special-treated metal powder, non-toxicasphalt, alpha-carbonized high polymer, S-802 adjuvant, Z-adjuvant and non-toxic plastic stabilizing agent as raw material, mixing them in a high-speed mixer, Bandury mixing, discharging material forstand-by, them making metal powder undergo the processes of high-temp. removing oxygen and removing rust, adding S-802 and Z-S adjuvants to obtain treated metal powder for stand-by, finally, using double-roll mixing machine to mix said materials at 150 deg.C, rolling and curing, feeding said material sheet into three-roller calender to obtain the composite plastic film layer product.
