The thermal conductivity of
nano-magnesium oxide is above 30W/(m.k). After surface treatment, it has better
contact with resin. Light weight, high insulation, and excellent thermal
conductivity, can be filled in large quantities. It is one of the excellent
fillers for thermally conductive rubber, thermally conductive plastic, and
thermally conductive adhesives.
Nano-magnesium oxide special for
thermal conductivity has high purity, good whiteness, small particle size and
uniformity, good dispersibility, can be used for thermal conductivity of
thermally conductive silicone sheets, thermally conductive resins (PA6, PP,
PPS, ABS) and other materials, through the necessary surface modification
treatment The addition amount can reach 70-80 parts, and the thermal conductivity
can reach up to 5W/mK.
The performance of magnesium oxide
filled thermally conductive silicone rubber is studied. The results show that
when the amount of magnesium oxide is less than 200 parts, the thermal
conductivity and tensile strength of the small particle size magnesium oxide
filled silicone rubber are greater than that of the large particle size
magnesium oxide filled silicone rubber, but the tensile elongation is the
opposite; When the ratio of magnesium oxide/small particle size magnesium oxide
is 100/100, the thermal conductivity of silicone rubber is the largest; adding
an appropriate amount of silane coupling agent is beneficial to improve the
thermal conductivity of silicone rubber, and the best dosage is about large
particle size oxidation 0.5% of magnesium consumption.
