“…Ahmed et al (2015) telah mempelajari pengaruh penambahan nano silika pada campuran NR dan SBR pada berbagai rasio dengan hasil kekuatan tarik, modulus elastis, kekerasan, abrasi, dan ketahanan sobek sangat baik, sementara pada kenaikan rasio nanosilika dalam matriks karet sifat mekaniknya terjadi penurunan. Menurut Ulfah et al (2015) pembuatan vulcanizate karet dengan rasio CB/Si dapat meningkatkan ketahanan abrasi, tegangan tarik pada perpanjangan 300%, dan kekerasan.

“…Thus, basic functional groups are already present on the surface of CBs produced at high temperature. For this reason, the intensity of the oxygen-containing groups rapidly increases through an acidproved mechanical properties, such as tensile strength, tearing strength, hardness, and abrasion resistance [4,[22][23][24][25].…”

Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial ad hesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced rubber composites are discussed.

ZnO Nanoparticles Bonded to SiO₂ Filler as a Curing Accelerator in Cold Vulcanizing Adhesives

The aim of this study is to investigate the interaction of ZnO/SiO2 particles between the chloroprene rubber and its effect on the cure characteristics and mechanical properties of the cold vulcanizing adhesives. Curing efficiency and mechanical properties of ZnO/SiO2 filled adhesives were compared with SiO2 filled adhesives. ZnO nanoparticles were bounded to SiO2 spherical nanoparticles by hydrolysis and condensation process. The morphology and elemental content of ZnO/SiO2 particles were investigated by scanning electron microscopy and energy dispersive spectroscopy. The ZnO/SiO2 particles were then blended with chloroprene rubber as accelerator during the vulcanization process. Cure characteristics, which are scorch time (ts2), cure time (tc90), maximum torque (MH ) and minimum torque (ML) of the rubber compounds were determined at 190• C with a moving die rheometer. The fabric conveyor belt was used for measuring adhesive strength of the adhesives. The fabric conveyor belt was used for measuring adhesive strength of the adhesives. Application of the cold vulcanizing adhesives to the fabric conveyor belt was carried out at three different times (4, 8, and 24 h), 25• C temperature and 0.3 kg/cm 2 pressure. The results showed that ZnO/SiO2 particles provided a higher adhesive strength than silica in the 4, 8, and 24 h of adhesion. ZnO/SiO2 filled rubber blends gained superior vulcanization characteristics by the increasing cure rate index with the reducing cure time and scorch time. It has been concluded that ZnO/SiO2 particles can be used as a new curing accelerator and simultaneously reinforcing filler.
