Preparation and Performance of cis-Polybutadiene Rubber Composite Materials Reinforced by Organic Modified Palygorskite Nanomaterials

Abstract EN

The hydrophilic character of palygorskite has been modified by grafting organic group and controlling surface energy for improving compatibility of palygorskite in rubber matrix using palygorskite as cis-polybutadiene rubber fillers.

The effects of coupling modification on the performance of cis-polybutadiene rubber materials filled with palygorskite were investigated, and the influence of coupling agent dosage on their mechanical properties was also studied.

The results indicated that the mechanical performance of cis-polybutadiene rubber materials reinforced by modified palygorskite could be improved significantly, and the tensile strength and tearing strength increased by 122.5% and 107.6% at the optimal dosage (15%) of coupling agent 3-mercaptopropyl trimethoxysilane.

Moreover, the reinforcement mechanism of rubber composite materials as prepared was also analyzed.
