A PROCESS FOR THE MANUFACTURE OF A PASSIVE ENERGY DEVICE (PED) FROM A HYSTERETIC SHEAR POLYMER


Indian patent filed

Patent Grant No: 232989

Date: 24.03.2009

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


Competing Features Passive energy dissipation devices are like

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.


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. Major Raw Materials to be Utilized Natural Rubber, Rubber with high damping additives, mild steel, adhesive chemicals

9. Major Plant Equipment and Machinery

Required

Normal rubber vulcanizing system and manufacturing facility available in any rubber product manufacturing plant

10. Techno-Economics Imported dampers are at least three times more expensive than the developed products

11. Technology Package Design methodology and manufacturing process of the PED device
