    Effect of Cenospheres in Thermal Insulation of Emulsion Paint
    (UMT.Lahore, 2018) MUHAMMAD RIZWAN RAZA
    The major aim of this research was to make thermal insulation emulsion paint and to study its thermal insulating properties along with other properties such as chemical resistance, dispersion and hardness with different sized “cenospheres”. Emulsion (water base) paint was made from regular white titanium dioxide which was produced by sulphate process and beige Titanium dioxide (Hitox) was produced by chloride process containing different concentrations of additive fly ash particles “cenospheres”. Cenospheres are the unburnt the particles of coal, wood and rice husk, having amazing properties and a great potential to be used as industrial product. Properties like heat insulation with cenospheres and without cenospheres in the sample of emulsion paint were studied at the temperature 8-10 oC in different time exposure (35-120 minutes). Chemical resistance was observed to be more in case of different samples having cenospheres and was less for those without cenospheres. Tinting power and reflectance were then studied by ASTM methods. To get the heat insulation effect in emulsion paint, different compositions of cenospheres were used as additives. Results showed that cenospheres which are smaller in size have excellent heat insultion properties. They can be also used as fillers in the paint which may reduce the cost of the end product that is emulsion paint.
