Fabrication and characterization of rice bran carbon/styrene butadiene rubber composites fabricated by latex compounding method

Abstract

Novel rice bran carbon (RBC) filled styrene butadiene rubber (SBR) composites were fabricated by latex compounding method (LCM). The chemical structure determination and the static precipitation experiments definitely authenticated the hydrophilicity of RBC, which enables RBC to be uniformly dispersed in water without surface modification and thereby compounded with rubber latex directly. The SBR/RBC composites prepared by LCM exhibited homogeneous filler dispersion state and superior mechanical properties compared with those compounded by solid compounding method (SCM). The vulcanization properties, mechanical properties, thermal stabilities, and swelling properties of SBR/RBC composites prepared by LCM were studied. It was revealed that the tensile strength, modulus, and tear strength of SBR/RBC composites increased correspondingly as the RBC loading increased from 0 to 80 phr. The decomposition temperature would stop rising when the filler loading exceeded 40 phr. The significant increases of the crosslink density with increasing filler volume content indicated the reinforcement effect of RBC. POLYM. COMPOS., 00:000-000, 2015.

Thermal Performances of UHMWPE/BN Composites Obtained from Different Blending Methods

“…e IPDT can be usually attributed to the unstable parts in composites, indicating that the higher IPDT is, the better the thermal stability of composites is. e required for thermal decomposition of the UHMWPE/BN composites can be reckoned by the Horowitz-Metzger integral kinetic method according to Equation (5) [31][32][33].…”

Influence of the hybrid materials based on carbon nanotubes and tannic acid on the rheological, thermal and mechanical performances of nitrile butadiene rubber composites

“…Scientists are working on carbon materials based on rubber composites due to the extraordinary properties of carbon‐based fillers . For instance, rubber composites filled with carbon black, rice bran carbon, bamboo charcoal, and graphene have been an increasing interest for improved mechanical, thermal, electrical, thermal conductivity as well as gas barrier properties of rubber. Considering the relatively low density, exceptional thermal, mechanical and electrical properties, carbon nanotubes (CNT) are the ideal candidates for the ultimate reinforcements in elastomer composites .…”

Improving aramid pulp dispersion in epoxy resin via the in situ preparation of SiO2 on an aramid pulp surface

“…However, such methods involve the treatment of aramid fibers with a diameter of 12 μm; when these methods are applied to highly fibrillated AP with a fiber diameter of less than 1 μm, fibrils adhere to one another and impair the dispersity and opening property of AP; as such, it is difficult to be used in applications . Inorganic fillers such as ZnO, TiO2, SiO2, and rice bran carbon were used in an epoxy matrix or rubber for reinforcing or toughening …”

“…[13,14] Inorganic fillers such as ZnO, TiO2, SiO2, and rice bran carbon were used in an epoxy matrix or rubber for reinforcing or toughening. [15][16][17][18][19][20] In this study, SiO 2 was synthesized on the surface of AP at an optimum tetraethyl orthosilicate (TEOS) concentration to improve the dispersion of AP in epoxy. SiO 2 nanoparticles formed on AP, thereby causing fibrillary AP to separate from one another and disperse easily in epoxy resin.…”
