Abstract
In this work, a pure gum mould made of prevulcanized natural rubber/cloisite-Na
+ nanocomposite
(PVNR/CN) was prepared and characterized for ornament application. The suitable conditions
to prepare PVNR/CN latex mixtures and the properties of the resulting PVNR/CN nanocomposites
were investigated. The optimum CN concentration in the latex mixture was 1.0 phr, with the
properties of 60 wt% total solid content, more than 600 sec mechanical stability time, lower
than 350 cP Brookfield viscosity, and pH 10. The properties of PVNR/CN nanocomposite showed
high strength, moderate hardness, and good thermal stability. The morphology by TEM showed
well dispersion of CN particles in between the rubber dispersoid. The PVNR/CN nanocomposite
as a mould was evaluated by shrinkage measurement. The presence of 1.0 phr CN in the
PVNR/CN nanocomposite achieved the least shrinkage. The reproduced object using the PVNR/
CN nanocomposite as a mould showed complete fine details similar to the original object via
visual observation.
