Description
Technical field
The present invention relates to a kind of water paint and preparation method thereof, more particularly to a kind of water-based cooling coating and its preparation side
Method.
Background technology
Heat radiation coating is a kind of by strengthening heat source surface infrared emittance, so as to improve the work(of body surface radiating efficiency
Can coating.Traditional heat-dissipating pattern mainly has heat transfer, convection current and heat loss through radiation, is much needing the field of high efficiency and heat radiation, due to
Limited by space, size and environment, it is impossible to heat exchange is gone out using the form of acceleration forced convertion, and only passes through heat transfer
In the case of demand can not being met again, enhancing infra-red radiation radiating is preferred solution.Because many materials are equal in nature
With very high heat radiation system, such as in itself, but its thermal conductivity is very low for coating resin, very big with heat dissipating substrate thermal contact resistance,
The effect for accelerating the radiating of substrate infra-red radiation can not be realized.Therefore, the lifting of infrared heat radiation coating performance is dependent on high red
External radiation rate, high thermal conductivity and low interface resistance.

This simultaneously, the boron nitride of micron order yardstick is a kind of conventional heat filling, and the requirement of its dispersing technology is far below to nano carbon material
The requirement of material, and its large-size particle is more conducive to form effective passage of heat.But its infrared emittance is relatively low, it is impossible to give full play to
The effect of multiple radiating mode.
Research finds that thermal conductive ceramic filler is combined addition with nano-carbon material can significantly improve coating matrix thermal conductivity,
It is more preferably more notable than independent additive effect, show a kind of multiple dimensioned collaboration enhancing phenomenon.But it is this to be simply mixed in addition pattern,
Because nano-carbon material and thermal conductive ceramic filler are that random distribution is contacted, and contact area is small, and both thermal contact resistances are very big.
