Thi thesis details the potential use of white lice husk ash (WRHA), which
1I ually contains around 96%(w/\\). silica as filler in natural rubber
compounds. The loading levels of WRHA with deferent composition with
natural rubber have been studied. The level with optimum physical properties
was found to be as 10 phr loading and deterioration of properties were
observed with further increase of loading levels of WRHA.
However, it was feel that WRHA could be used as cost effective filler with
modification to surface characteristics. Incorporation of silane type coupling
agent (A 1289) has resulted in improving the curing characteristics as well as
physicalproperties ofWRHA filled natural rubber compound.
The natural rubber compound containing 30 phr of WRHA and O.Sphr of
Al289 showed higher physical properties indicating between the improved
interactionbetween WRHA and the natural rubber phasae.
