It chooses the heat sink material being prepared and carries out performance detection respectively,
Volume resistivity is surveyed by GB/15662-1995 standards；Thermal conductivity is tested by III thermal conductivity factor instruments of DRL-, and method is hot-fluid
Method, testing standard MIL-I-49456A；
Test result
The experimental results showed that the composite guide hot glue nanometer heat sink material that the present invention uses has good heat dissipation effect, material is in state
Under family's standard test condition, thermal conductivity is higher, illustrates that heat dissipation effect is better, conversely, effect is poorer；Embodiment 1 arrives embodiment
10, volume resistivity reaches insulating materials standard, but thermal conductivity changes greatly；As different from Example 1, embodiment 2 to
Embodiment 10 changes the proportioning that primary raw material forms in composite heat dissipation material respectively, has in various degree to the heat dissipation performance of material
Influence, in silica flour, β-Si3N4Powder quality proportioning is 5：2, when other dispensing dosages are fixed, heat dissipation effect is best；Reference examples 1 to
Reference examples 2 do not add silica flour and β-Si3N4Powder is compound, and heat dissipation effect is decreased obviously, and illustrates conductive particle silica flour and β-Si3N4
Powder component material heat dissipating has an important influence on；Reference examples 3 to control 4 changes base fluid mixture ratio, organic monomer dosage
It reduces, heat dissipation effect is obviously deteriorated, and it is critically important to material thermal diffusivity to illustrate that base fluid is modified；Reference examples 5 are not added to reference examples 6
Initiator and ammonium hydroxide, foamed process can not be completed, and effect is also bad, illustrate that foam process is affected to material modification；Control
It is 1 that example 7 to example 8, which changes base fluid and powder mixing ratio,:5, heat dissipation effect is obviously deteriorated, and illustrates that the dosage of base fluid answers silicon rubber
It is very big to close influential effect；Reference examples 9 and reference examples 10 change modified beta-silicon nitride powder silicon rubber proportioning, and thermal conductivity is still not
Height, illustrates that filler is excessively very few, is all unfavorable for the heat conduction of material；Therefore it is radiated using the composite guide hot glue nanometer that the present invention uses
