Application of Surface Modified Nano Zinc- Oxide in Sulfur Vulcanization of Tire Tread Compound I- Azad University, North Tehran Branch IRAN Rubber Industries Engineering and Research Institute Dr. Saeed Taghvaei Mercedeh Malekzadeh Dr. Saeed Taghvaei Mercedeh Malekzadeh
Contents Nanotechnology More common nanomaterials used in rubber field Problems consequent using Nano ZnO in rubber matrix Surface modification of Nano ZnO Application of surface modified Nano ZnO in tire tread compound Results
Nanotechnology Nanotechnology is a broad field of applied science and technology focused on controlling and exploiting the structure of matter on a scale below 100 nanometers.
Why Properties Change in Nano Scale Increased ratio of surface area to volume present in many nanoscale materials opens new possibilities in surface-based science. Quantum effects impacting behavior of materials.
Nanomaterials Used in Rubber Field Nano activator (ZnO) Nano filler (CNT, Nano Silica, Nano Clay)
Small size Problems consequent using nano ZnO Hydrophyl surface Agglomeration
