زيادة العزل الحراري لراتنج الفنيل أستر بإضافة دقائق أوكسيد المغنيسيوم إليه

الملخص EN

This research aims to study the effect of addition magnesium oxide particles on thermal conductivity vinyl ester resin, where this oxide added as a filler with different weight percentages (10%,20%) to resin, and study the effect of this additive on heat flow thermal insulation of the resin.

Fourier equation was used to calculate the changing in thermal conductivity coefficient (k) for vinyl ester resin before and after addition of magnesium oxide, where the results show improved retarding heat flow and increased thermal insulation of the resin by reduced thermal conductivity value after oxide addition, and the value of thermal insulation will increased with increasing of additive percentage of magnesium oxide where it change from(0.33 W/m.ºC) before added oxide to (0.21 W/m.ºC) after addition (20%) from oxide at temperature (40 ºC) .
