              Effect of replacing the amount of air glass beads and carbon black on

                 Abstract: In this paper, reducing the density of natural rubber by adding air glass beads as a filler to
             replace carbon black was explored. Experiments show that with the increase in the number of air glass beads
             to replace carbon black, the highest curing torque M H  of natural rubber continues to increase. However, the
             tensile strength of vulcanizates and the constant elongation stress at various levels continue to decrease,
             the elongation at break continues to increase, and the slope of the stress-strain relationship curve gradually
             decreases. Experiments show that adding glass beads can significantly reduce the density of the vulcanizate,
                                                                                                           3
             and when the glass beads/carbon black ratio in the formula is 40/40, the density can reach less than 1 g/cm .
