Nano-aluminum nitride and ultra-fine
aluminum nitride powder are prepared by a special process, with high purity,
small particle size, large specific surface area and high surface activity. The
powder modified by surface modification does not undergo hydrolysis reaction,
and oxygen content Very low (<0.1%), the effect of insulation and thermal
conductivity is very obvious. Used in polymer resin, the viscosity is not
obvious, it is the best high thermal insulation insulating filler. Nano-aluminum
nitride is a diamond-like nitride, which can be stabilized up to 2200 ° C, high
room temperature strength, and the strength decreases slowly with increasing
temperature; nano-aluminum nitride powder has good thermal conductivity, small
thermal expansion coefficient, thermal conductivity The theoretical value of
the rate is 320w/mk, which is similar to copper. At the same time, it is highly
insulated. The resistivity is above 10 to the power of 15 and can withstand
1400 degrees. It can greatly improve the thermal conductivity of plastics and
silicone rubber. It is good resistance. Thermal shock material, strong
resistance to molten metal corrosion, is ideal for casting molten iron,
aluminum or aluminum alloy; nano-aluminum nitride has excellent electrical
insulation and good dielectric properties; nano-aluminum nitride has good
injection Forming properties; used in composite materials, good compatibility
with semiconductor silicon, good interface compatibility, can improve the
mechanical properties and thermal conductivity of composite materials.
Application field
1. Manufacturing integrated circuit
substrates, electronic devices, optical devices, heat sinks, high temperature
germanium to prepare metal-based and polymer-based composite materials,
especially in high-temperature sealing adhesives and electronic packaging
materials to improve the heat dissipation performance and strength
characteristics of materials. Good application prospects can replace the
currently imported micron aluminum nitride;
2. Thermally conductive silica gel and
thermal conductive epoxy resin: Ultra-high thermal conductivity silica gel is
prepared by using nano-aluminum nitride produced by our company. It has good
thermal conductivity, good super-electrical insulation, wide electrical
insulation and use temperature ( Working temperature 80-250 ° C), low
consistency and good construction performance. The products have reached or
exceeded the imported products, because they can replace the similar imported
products and are widely used in the heat transfer medium of electronic devices
to improve work efficiency. Such as CPU and heat sink gap, high power triode,
thyristor components, diodes, heat transfer medium at the slits in contact with
the substrate. The nano-thermal paste is used to fill the gap between the IC or
the triode and the heat sink, increasing the contact area between them to
achieve better heat dissipation;
3. Nano-lubricating oil and anti-wear
agent: The modified nano-aluminum-nitride ceramic particles added in the
nano-ceramic engine oil act on the friction pair metal surface inside the
engine with the lubricating oil, and are activated under the action of high
temperature and extreme pressure, and are firm. It is infiltrated into the
dents and micropores of the metal surface to repair the damaged surface and
form a nano ceramic protective film. Because of the isolation of the film, the
friction caused by the relative motion between the parts only acts on the
protective film. The nano-ceramic particles transform the partial friction
between the friction pairs into a rolling friction like a small ball. Greatly
reduce friction, reduce the friction between moving parts to near zero, and
provide super anti-wear protection for the engine. By improving lubrication, it
can reduce the friction coefficient by more than 80% and improve the anti-wear
ability by more than 350%. Reduce wear by more than 80%, extend the life of
mechanical parts by more than 3 times, reduce downtime, reduce maintenance
costs, extend overhaul period by more than double, save energy by 10%-30%, and
increase equipment output power by 20%-40%. Only two tenths to one thousandth;
4. Application in high thermal
conductivity plastics: The modified nano aluminum nitride powder can greatly
improve the thermal conductivity of plastics. By adding 1% to the plastic in
the experimental product, the thermal conductivity of the plastic can be
increased from 0.3W to 3W, and the thermal conductivity is increased by more
than 10 times. Currently mainly used in PVC plastics, polyurethane plastics, PA
plastics, functional plastics, etc.;
5. Nano-aluminum nitride can be used to
smelt non-ferrous metals and semiconductor materials gallium arsenide,
evaporation boat, thermocouple protection tube, high temperature insulation,
microwave dielectric materials, high temperature and corrosion resistant
structural ceramics and transparent nitriding Aluminum microwave ceramic
products.
