OPTIMIZATION OF CATHODE WASTE MATERIALS ON EPOXY BASED CONDUCTIVE PAINT PROPERTIES

Battery waste of as filler was mixed with Epoxy Resin and Polyamide at the
preparation of electrically conductive paint coating, which led to enhancement of
their electrical-mechanical properties. In this study, only the optimized mixing ratio
and particle size was used in the preparation which determined from experiments of
mixing ratio and particle distribution analysis. The grinding process, particle analysis
distribution, electrical resistivity, macrostructure and adhesion of the conductive
paint test have been carried out using Grinder, Sieve Machine, Mnltimeter and
Revetest Scratch Tester. Optimized particle size of filler was used in the study is 150
microns and optimum mixing ratio between Epoxy Resin and Polyamide is 1:1. The
mixing ratio choose because has fast curing time and good mechanical properties.
The electrical resistivity decreased as the concentration of filler increased, from the
result the maximum value was 24.13 x 106 n at 40% of carbon electrode (CE) filler.
The adhesion properties of the paint decreased as concentration of filler increased,
while the dispersion of filler in the conductive paint became better with the increased
of filler. Between the three fillers CE, CW and MIX used in the study, CE filler has
the best mechanical and electrical properties.
