Effect of the silane coupling agent on the physicomechanical properties of EPDM/SBR/AL₂O₃ rubber blend nanocomposites

Abstract

In this study, ethylene propylene diene rubber (EPDM)/styrene–butadiene rubber (SBR) blend nanocomposites filled with alumina (Al2O3) nanoparticles were prepared. Al2O3 nanoparticles were used with or without surface treatment by the silane coupling agent bis[3 (triethoxysilyl)propyl]tetrasulfide, and Al2O3 nanoparticle–filled EPDM/SBR was compared with carbon black. The influences of the filler type, size, concentration, and surface property on the curing characteristics, degree of filler dispersion, mechanical properties, and morphological characteristics of the EPDM/SBR nanocomposites were investigated. We found that the mechanical and curing properties of the nanocomposites were enhanced owing to the presence of Al2O3 nanoparticles. The addition of the silane coupling agent further improved the properties of the nanocomposites.

Improving the Mechanical/Anticorrosive Properties of a Nitrile Rubber-Based Adhesive Filled with Cerium Oxide Nanoparticles Using a Two-Step Surface Modification Method

“…There is also a tetrasulfide group in the molecule of TESPT, which participates in rubber curing. This forms chemical bonding between nanoparticles and rubber chains, improving nanocomposite properties. ,, …”

“…This forms chemical bonding between nanoparticles and rubber chains, improving nanocomposite properties. 2,7,12 Ansarifar et al 5 studied the effects of using TESPT-grafted silica nanoparticles on the mechanical properties of styrene butadiene (SBR), butyl (BR), NBR, and natural (NR) rubbers. It was found that using the modified nanoparticles caused a lowered need for the incorporation of a vulcanization agent (i.e., sulfur).…”

A Review of EPDM (Ethylene Propylene Diene Monomer) Rubber-Based Nanocomposites: Properties and Progress

“…Blends of EPDM/styrene butadiene rubber (SBR) have been analyzed by some authors [ 73 , 74 , 75 ] regarding the effect of different nanocomposite blends, such as reinforcing agents, and the consequent impact on mechanical properties. Broad engineering applications can be found using these kinds of (EPDM/SBR) rubber compounds, such as tires, seals, conveyor belts, and electrical cables, among others.…”

Studies on swelling behavior, mechanical and thermal properties of ternary rubber blend composites in the presence of compatibilizers

“…The polymer blend is a well-known approach in the rubber industry to create rubber compounds with specific properties that cannot be attained from individual polymers. Polymer blends' objectives include improving the physicomechanical, swelling properties, cost-effective material, high aging characteristics and long service life (Khimi and Pickering, 2014;Jong, 2018;Abdelsalam et al, 2022). Most polymer blends are immiscible due to the lack of interactions between the components of blends at the interfaces, whereas a compatibilizer should be incorporated between the components of blends (Jong, 2018;Abdelsalam et al, 2019Abdelsalam et al, , 2021.…”
