| titleOfInvention | Soundproofing material using waste rubber and its manufacturing method |
| abstract | The soundproofing material using waste rubber according to the present invention includes 30 to 70 parts by weight of waste rubber powder, 30 to 70 parts by weight of polyolefin resin, 1 to 20 parts by weight of foaming agent and 0.5 to 1 parts by weight of crosslinking agent, and further an auxiliary foaming agent. It may be prepared by further adding 0.1 to 0.5 parts by weight.n n n The soundproofing material using such waste rubber is an azo system such as waste rubber powder, polyolefin resin, azobiscarbonamide, barium azodicarboxylate, dinitrozopentamethylenetetramine, p, p'-benzenesulfonyl semicarbazide At least one blowing agent selected from nitrozo and sulfonyl semicarbazide, at least one crosslinking agent and methyl oxide selected from peroxide compounds such as dicumylperoxide, tert-butylperoxyketone, tert-butylperoxybenzoate , 1 step of stirring and mixing auxiliary foaming agent, such as higher fatty acid at a temperature of 80 ~ 120 ℃, the first step of the processed material into a mold of a predetermined size and heated for 30 to 50 minutes at 140 ~ 150 ℃, 80 ~ 120 bar conditions By two steps of molding, and by the method comprising three steps of placing the fixed plate on both sides of the upper and lower sides of the two-stage processed material and then heated to 170 ~ 180 ℃ foaming. Is Joe.n n n Such soundproofing material has excellent soundproofing effect by sound-absorbing combination of sound absorption of waste rubber and microbubble of polyolefin foam. |
