Surface modification of novel rice bran carbon functionalized with (3-Mercaptopropyl) trimethoxysilane and its influence on the properties of styrene-butadiene rubber composites

Abstract

In the present study, surface modification of novel environment-friendly Rice Bran Carbon was carried out by mixed acid treatment followed by reaction with multifunctional silane, (3-Mercaptopropyl) trimethoxysilane. Then a new class of styrene-butadiene rubber/Rice Bran Carbon composites were prefabricated by using latex compounding method on the basis of pretreatment of RBC. Specifically, extra 3phr 3-MPTMS was added into the composites to construct a systematic filler-silane-matrix net framework. The chemical interaction mechanism of silane agent with the oxidized RBC was confirmed by Fourier Transform Infrared Spectroscopy, Energy Dispersive Spectroscopy, Thermogravimetric Analysis and Field Emission Scanning Electron Microscopy. The effect of silane modified RBC on the mechanical, wear and friction property of SBR vulcanizates was investigated.
