Abstract HXNBR (Hydrogenated Carboxylated Nitrile Rubber) has very good heat ageing resistance and oil resistance. A novel accelerator system is designed to bring about the vulcanization of HXNBR at room temperature. The room temperature cured samples showed good mechanical properties equivalent to those of high (150 °C) temperature cured samples. Natural rubber vulcanizates are highly prone to oxidative and ozone degradation. The oil resistance of natural rubber vulcanizates is also very low. The oil resistance, ozone and oxidative degradation resistance of natural rubber vulcanizates are considerably improved by placing a thin coating of HXNBR over it.

Attapulgite (AT)/natural rubber (NR)/ styrene-butadiene rubber (SBR) nanocomposites have been prepared after attapulgite was modified by different coupling agent. The treatment of AT caused the adhesion between AT nanorods and the nature rubber/styrene-butadiene rubber was improved, which enhanced the tensile properties of the matrix. The tensile strength of composites attained 15.6 MPa after AT was modified by 3%wt Si-69 coupling with addition of 20 phr.

Natural rubber (NR) nanocomposites were prepared in a double-roller plasticator mixer with purified attapulgite (PAT) or modified attapulgite, which was treated at 450°C (PAT-450) and 850°C (PAT-850) for two hours. The structures of the pristine, purified, and modified attapulgite were characterized by FTIR, TEM, XRD, and BET. The results indicated that the structure of attapulgite changed with the increased temperature. The effects of the PAT treatment and content on the mechanical properties of the NR nanocomposites were also investigated. The results showed that AT increased curing process of natural rubber. A significant improvement in the tensile strength, wearability, and solvent resistance of the nanocomposites was observed with the addition of different types of attapulgite as compared to those of pure NR. Scanning electron microscope images showed that the filler was located at the interface, which induced compatibilization in the immiscible blends. Thermogravimetric analysis revealed a significant improvement in the thermal stability of the NR/PAT nanocomposites.
