The particle size of carbon black affect the performance impact on the particle diameter of carbon black rubber tensile strength, tear strength, abrasion resistance has a decisive role, Figure 3-7 and Figure 3-8 can be seen from Figure 3-6, on other properties of the particle size. Small size, tear strength, modulus and hardness are improved, and the elongation decreased elasticity and compression set small changes. This is because the small particle size, surface area, making circles between rubber and carbon black area, the interaction between the two combine to produce more glue. Affect the structure of carbon black structure has a greater impact on the modulus and hardness. Because the presence of the filler reduces the elasticity of the gum Hiro of the volume fraction of the rubber macromolecules, high structure carbon black gum more inclusive, to a greater extent reduce * the volume fraction of the rubber macromolecules. Only the structure of the abrasion resistance in harsh conditions before wear to show some improvement. Structure also has some influence on other properties. Carbon surface properties affect the performance of vulcanized rubber (1) activity and crystal size affect the surface morphology of the surface of carbon black particles of carbon black particles for reinforcement? With a certain degree of influence. For example, the ISAF at 850? 1000 ° C is heated, the heating time control, then the suspect black particles graphitized surface portion, and the crystallite size increases, resulting in decrease in the reinforcing effect of carbon black. Surface roughness of the carbon black particles rubber reinforcing negative, because the rubber macromolecules difficult to enter these micropores.
