The Iranian researchers at Amirkabir University of Technology, Tehran, managed to prolong the lifetime and reduce the weight of rubbers used in truck tires by incorporating silicate nanocomposites in their blends.
Strengthening of rubbers is of specific importance in auto industry. Carbon black is known for long as the most widely used reinforcement in rubber blends. However it is bound to drawbacks like having the single color of black, dependency on petroleum resources, reducing processability of the blend as its quantity increases, and increasing material density.
Using layered nanosilicate as a strong and multipurpose reinforcement in the production of polymeric nanocomposites has attracted lots of attention in recent years.
“The application of layered nanosilicate results in the reduction of carbon black quantity used in rubber blends thus reduces the density of blend so that it is possible to synthesize products with less weight," Azam Jalali Arani, faculty member of Polymer Engineering Department, Amirkabir University of Technology, said in an interview with the INIC news service.
"Tires lightening decreases fuel consumption of vehicles as well as the environmental pollution and consequently saves the energy consumption. Other specifications and final properties of the blend would also be improved and tire lifetime would be increased”, she added.
Jalali Arani first formulated the nanosilicate incorporated rubber blend. Then she analyzed and determined the optimized conditions for preparation of this blend. After that, blending and producing the nanocomposite sample and also analyzing and testing the properties of sample vulcanization were done by rheometric test. Sample vulcanization and cure according to the results obtained from rheometric test and produced nanocomposite properties study were a part of research outcomes.
