Studies of application of carbon black in rubber Studied of the interaction between carbon black and SSBR showed that the chemical effect of carbon black and SBR rubber compound plays a dominant role as the rubber reinforcement . With decreasing particle size of carbon black, total combined rubber and chemical and physical bonding increases . The strength of carbon black reinforced SSBR rubber and vulcanized rubber changes according to carbon black particle size with curves are close to hyperbolic curves and dramatic change occurs in the vicinity of the carbon black particle size of 100nm, which showed that the chemical and physical effects between SSBR and carbon black surged with carbon black particle diameter of about 100nm and reinforcement role of the solid filler particles significantly increased. There is a reinforcement of the critical particle size. NMR Resonance crosslink density gauge characterized the influence of physical crosslinking density , chemical crosslinking density and the total crosslink density of the carbon black showed that with decreasing particle size of the carbon black, the physical crosslinking density increases and chemical and total crosslink density first decreases, then increases, the mutation occurs in l00nm . |
