1. Title of A PROCESS FOR THE MANUFACTURE Product/Process/Design/Equipment OF A PASSIVE ENERGY DEVICE (PED) FROM A HYSTERETIC SHEAR POLYMER 2. IPR Status Indian patent filed Patent Grant No: 232989 Patent/Copyright / Trademark Date: 24.03.2009 secured in India /Abroad
IPR Details 3. Application / Uses The main advantages of Passive Energy Dissipation Devices are: Improved Seismic Performance of structures Mitigating the damage of primary structures Easy Replacement after a major seismic event
4. Salient Technical Features including Passive energy dissipation devices are like Competing Features simple brace/ non-brace elements, which have been added to existing structures either during construction or in their service life as retrofit, to enhance the damping of a structure. Increased damping over and above the inherent damping of a structure shall reduce the effective seismic force transmitted onto a structure. They protect the main structural members from damage and function as “fuses” in an electrical circuit, which blows off in case of current surge and save the main equipment. CSIR-SERC has developed a special manufacturing process for the manufacture of these PED devices with improved adhesive and bonding properties.
The hysteretic shear polymer is based on Indian standard natural rubber (ISNR). The hysteretic shear polymer is prepared by processing the ISNR at a temperature in the range of 50°C to 100°C with suitable additives, such as china clay, semi- reinforcing furnace (SRF) carbon black, zinc oxide, steric acid, vulcaniser sulphur, tetra methyl thiuram (TMT), 2-mercapto benzo thiazole (MBT) and spikel oil. The hysteretic shear polymer so obtained is fabricated to make a passive energy device (PED). The passive energy device thus obtained provides shear strain as high as 200% linearity and shear strength > 25 kg per sq. cm which is useful for dissipating shear load due to seismic forces in buildings. 5. Level / Scale of Development Laboratory level model and prototype have been developed. 6. Environmental Considerations The novelty has been achieved by the non- obvious inventive steps of processing natural polymer (ISNR) with additives and hence providing an environment friendly as well cost effective process as compared to the synthetic based polymers. 7. Status of Commercialization The process of commercialization of process for the manufacture of PED from a hysteretic shear polymer have to be initiated with possible Rubber Manufacturers in India. 8.
