Abstract

This project aims to study (1) whether rice husk ash can help increase hardness and thermal insulation
for rubber tiles and (2) whether a coating of titanium dioxide can help reduce the temperature in the
house. From the experiment, the amount of rice husk ash used is 0, 20, 40, 60 and 80 phr. The types of
mechanical property test studied are tensile strength, 100% modulus, hardness and elongation at break.
The results show that roof sheets with 60 phr rice husk ash have the best mechanical properties.
Consistent with the insulation test results. After that, rubber sheets containing 60 phr rice husk ash was
sprayed with 15% of TiO2, were the most effective used for insulation by more than 21% and caused
the air temperature under the tiles to decrease 2.97% compared to the 60 phr roofing sheet.
