Study of postvulcanisation of natural rubber latex films
thesis
posted on 2010-11-05, 12:00 authored by Jacqueline SmeatonTensile strength–modulus relationships established for postvulcanised latex films have been
found to show characteristics of both prevulcanised latex and dry rubber curves. The curves
depend upon the accelerator system used, as with dry rubber. They passed through their
maxima after which tensile strength fell, with the down-turn less pronounced than for
prevulcanised latex but greater than for dry rubber. The results suggest that postvulcanised
latex films remain particulate rather than homogeneous.
Processes known to affect prevulcanised latex films were applied to postvulcanised latex films.
These included stirring and maturation of latex, different conditions for drying films and leaching
with water and solvents, but only stirring had a significant effect. Stirring was essential to
produce homogeneous latices for films with consistent chemical compositions and physical
properties. [Continues.]
