Abstract:
In the present work, studies on vulcanization, rheology
and reinforcement of natural rubber latex with special reference
to accelerator combinations, surface active agents and gamma
irradiation have been undertaken. In vulcanization, the choice
of vulcanization system, the extent and mc-zie of vulcanization
and network structure of the vulcanizate are important factors
contributing to the overall quality of the product. The vulcanization
system may be conventional type using elemental sulfur
or a system involving sulfur donors. The latter type is used
mainly in the manufacture of heat resistant products. For improving
the technical properties of the products such as modulus
and tensile strength, different accelerator combinations are used.
It is known that accelerators have a strong effect on the physical
properties of rubber vulcanizates. A perusal of the literature indicates that fundamental studies on the above aspects of latex technology are very limited. Thereforea systematic study on vulcanization, rheology and reinforcement of natural rubber latex with reference to the effect of accelerator combinations, surface active agents and gamma irradiation has been undertaken. The preparation and evaluation of some products like
latex thread was also undertaken as a part of the study.
The thesis consists of six chapter
