Abstract
Solid waste, such as various car tires, poses a significant threat to the environment and human health, as it takes several decades to decompose in the soil. Therefore, it has become necessary to pay attention to scientific methods for getting rid of these wastes, improving processes and methods of recycling them and benefiting from the products of those processes. The research focuses on developing a unique recipe based on synthetic rubber styrene-butadiene rubber. The physical properties, such as rheological and specific gravity and mechanical properties, such as hardness, were performed. The results showed a slight decrease in the curing time and vulcanization time with an increase in the percentage of waste fiber compared to the standard samples. This indicates that the recipe may scorch faster throughout the production process than regular samples and an increase in strength and viscosity upto the percentage load of 10%. Where there was a decrease in the amount of torque and viscosity of the recipe with a percentage load of 12.5%, indicating a weakness in the recipe or a reduction in the amount of bonding between the rubber chains of the samples, as well as an increase in the property of hardness and specific gravity with an increase in the loading percentage of wasted fiber. All previous results may support the use of waste fibers resulting from the tire recycling process in improving some physical and mechanical properties, albeit in crumbly proportions, as well as achieving environmental and economic goals.
