  The Research of Nano Aluminum Nitride in Thermal Conductive Plastic

  1.Thermal conductive silicone, and thermal conductivity of epoxy resin

  High thermal conductivity of nano AlN composite silica gel has good thermal conductivity, good electrical insulation, wide electrical insulation used temperature (working temperature 60 ℃ -- 200 ℃), low consistency and good construction performance.Products has reached or exceeded imports, because they can replace similar imported products, are widely used in electronic components of the heat transfer media an improve work efficiency such as CPU and radiator filler, power transistor, thyristor, diode, and heat transfer media contacted with the base material of fine seam . Nano thermal conductive paste can fill the interspace between the IC or triode with heat sink, increase the contact area between them to achieve better heat dissipation effect.

  2. The application of thermal conductive plastics: Nano aluminum nitride power can greatly improve the thermal conductivity of plastic materials.Products through the experiment in a ratio of 5-10** added to the plastic can make plastic thermal conductivity increase from the original 0.3 to 5. Thermal conductivity is increased more than 16 times. Compared with the thermal conductivity of filler on the market at present (aluminium oxide or magnesium oxide etc.), it has the characteristics of low added quantity, improvement of the product mechanical properties and more obvious thermal conductivity effects. Now manufacturers have procured related nano aluminum nitride in large scale and the new nano thermal conductive plastics will be put on the market.

  3.Other areas of application: application of nano aluminum nitride in smelting non-ferrous metal and semiconductor gallium arsenide crucible, evaporation boat, thermocouple protection tube, heat insulation, microwave dielectric materials, high temperature resistant and corrosion resistant structural ceramics and transparent aluminum nitride microwave ceramic products, and the current applications in PI resin, thermal insulating mica tape, thermal grease, insulating paint, and heat conduction oil, etc.
