Role of transition metal nanoceramics in rubber degradation

Plasticizer used in rubber processing. Plasticizers increase the plasticity of plastic. Fuel oil itself acts as a plasticizer. It was observed there was huge loss of plasticizer during storage and transport. To prevent this difficulty or in order to increase the life of plasticizer, transition metal ceramics were added in it. Nanoeramics were prepared by combustion method in which oxalic acid is fuel and nitrate salts of metal were self-oxidizing agents. It was notified that flash point of plasticizer increased significantly and viscosity of oil little decreased. Thermal stability, storage and transport quality of plasticizer was improved due to incorporation of transition metal ceramics in plasticizer. As a result thermal stability of rubber enhanced. Loss of rubber due to high temperature was prevented, hence degradation reduced. It was found that plasticizer (fuel oil) recovered after pyrolysis process and by products was minimized due to the nanoceramic powder.
