تأثير دقائق من أوكسيد المغنيسيوم في العزل الحراري لراتنج الأيبوكسي كونبكسترا (EP-10)‎

الملخص EN

Magnesium oxide with (5 μm) particle size with different Weight percentages (5%,15%,25%) was added to conbextra epoxy (EP-10) resin and measured the changing in thermal insulation to this resin .

Fourier equation was used to calculate the changing in coefficient of thermal conductivity (k) for conbextra epoxy (EP-10) before and after addition of magnesium oxide ,where the results show improved thermal insulation of the resin by reduced in thermal conductivity coefficient value after oxide addition , and the value of thermal insulation will increased with increasing of additive percentage of magnesium oxide ,where it change from(0.24 W/m.ºC) before added oxide to (0.16 W/m.ºC) after addition (25%) from oxide at temperature (40 ºC) which the best value from oxide additive .
