The effect of the elongation at break on the elongation of the accelerator DM/D and the amount of S-SBR/BR used in comparison with the effect of elongation on the elongation of the rubber, S-SBR/BR combined with the ratio, elongation at break With the increase of the accelerator DM/D, the usage rate is almost a uniform decrease. When the accelerator DM/D was used in a fixed amount, the elongation at break was relatively small with the change in the ratio of S-SBR/BR, but it was still seen that there was an optimum value. Therefore, when the amount of filler is certain, the amount of accelerator is the main factor affecting the elongation at break. Effect of carbon black/white carbon black and S-SBR/BR on the elongation at break of carbon black/white carbon black and S-SBR/BR. White carbon black used in comparison with the contour plot S-SBR/BR and the contour plot carbon black/white carbon black with the ratio of 40/20S-SBR/BR and the ratio of the contour plot accelerator DM/D and the amount used is 1.4/0.7 When the amount of accelerator is fixed, carbon black/silica is the main factor influencing the elongation at break. With the increase of the amount of white carbon, the elongation at break increases. The effect of S-SBR/BR on the elongation at break is very small. In summary, the effect of the accelerator DM/D on the elongation at break is large, while the elongation at break of the S-SBR/BR and the comparison compound has little effect. The orthogonal rotation design method can be used to meticulously and comprehensively characterize the influence of various factors and their levels on the properties of the rubber compound. The amount of accelerator DM/D is constant, the amount of white carbon black and S-SBR increases, and the tear strength of the rubber increases; the amount of white carbon black, accelerator, S-SBR increases or the amount of S-SBR and carbon black increases High tensile strength can be obtained with the accelerator DM/D and the amount of 1.2/0.6. The increase of the amount of carbon black, accelerator and S-SBR is beneficial to increase the tensile stress at 300%; when the accelerator DM/D and the amount is 1.4/0.7, the amount of white carbon increases, and the elongation at break increases. The effect of the combined use of S-SBR/BR on the elongation at break was insignificant.
