The effect of the amount of DBD on the properties of the tread rubber was investigated. The results show that the addition of peptizer DBD to the tread rubber reduces the Mooney viscosity of the rubber compound, and shortens the Mooney scorch time and t90. With the increase of the amount of DBD in the plasticizer, the plastic stability of the rubber compound increases. Large, carbon black dispersion improved, the wear resistance n’okuziyiza obukoowu bw’okunyigirizibwa (compression fatigue resistance) bwa vulcanizate tebwakyuka nnyo; Omuwendo gwa DBD ya peptizer bwe gwali 0.05~0.11 ebitundu, eby’obutonde eby’omubiri gwa vulcanizate byali bisinga.

The effect of tartaric acid, stearic acid and molten stearic acid on the properties of reclaimed rubber when the decomposing agent DBD was used as a regenerating activator was studied. The results showed that with the increase of the amount of tartaric acid, stearic acid and molten stearic acid, the sol content of reclaimed rubber increased, the crosslink density decreased gradually, the Mooney viscosity and Mooney viscosity Okweyongera, era amaanyi g’okusika okusooka ng’omuwendo gwa asidi wa tartaric ne asidi wa stearic guli 0{3}}6 ebitundu, omulimu omujjuvu gusinga; Omuwendo gwa asidi wa stearic ogusaanuuse bwe guba ebitundu 0.9, omulimu omujjuvu guba gusinga. n’okuwanvuya obudde bw’okuddamu okukola, ekirungo kya sol ekya rubber ekyaddizibwawo kyalaga omuze ogw’okugulu ogw’amaanyi, era crosslink density ne mooney viscosity byakendeera nnyo . amaanyi g’okusika n’okuwanvuwa mu kumenyawo okukendeera n’okukutula okuwanvuwa okw’okuzza obuggya. Ekiseera ky’okuzzaawo asidi wa stearic ekisaanuuse bwe kiba 20min, mooney viscosity eba wansi, omulimu gw’okukola guba musinga, amaanyi g’okusika n’okuwanvuwa mu kumenya biba bitono, obukaluba buba wansi, ate omulimu omujjuvu guba mulungi.
