NOISE BARRIER PANEL EMPLOYING HIGH-ATTENUATING RUBBER TO ATTENUATE VIBRATION AND NOISE

摘要

Disclosed soundproof plate has multiple through-holes, it is with another research, other described research sound-absorbing parts, it is used for from high-damping rubber order absorption transmitted noise with the leakage of the noise section for blocking sound-absorbing part and another research, store the sound-absorbing part and high part that rubber shock absorber insulate, another research is exposed to outside, so that surface includes a frame charging hole. High-damping rubber heat insulating part, isoprene liquid rubber, 10 to 30 parts by weight of carbon black per, 40 to the 70 parts by weight stearic acid of 100 parts by weight of natural rubber, 2 to 5 part by weight of zinc oxide (ZnO), 5 to 10 parts by weight N (1,3- dimethylbutyls)-N'- phenyl-p phenylenediamines, 3 to 5 parts by weight, 1 to 3 parts by weight of N- phenyl-N- isopropyl-p phenylenediamines, 5 pairs of 10 parts by weight of nanoclay, by the N tetrabutyls -2-[4-morpholinodithio sulfenamide 0.1 to 10 parts by weight, 1.A kind of vulcanizing agent pohamneun rubber compositions composition of 5 to 5 parts by weight.
