摘 要:The action of CeO2 powders in natural rubber was studied. The effects of particle size, content and surface modification of CeO2 powders on the properties of natural rubber was discussed. The results showed that the scorch and curing time of rubber decreased, the physic mechanical properties and aging resistance of natural rubber vulcanizates enhanced after filled with CeO2 powders. Especially tear strength and abrasion resistance increased much, and was raised 25% and 20% respectively. The surface of modified CeO2 powders had hydrophobic organize layer which could increase interface cohesion with the rubber and dispersity in rubber resulting in exerting reinforcement effect. The modified CeO2 powders improve the physic mechanical properties of rubber much compared with the unmodified CeO2 powders.
