Description

A kind of water-based cooling coating and preparation method thereof
Technical field
The present invention relates to a kind of water-borne coatings and preparation method thereof, particularly a kind of water-based cooling coating and preparation method thereof.
Background technology
Heat radiation coating is a kind of by strengthening heat source surface infrared emittance, thus improves the functional paint of body surface radiating efficiency.Traditional heat-dissipating pattern mainly contains thermal conduction, convection current and heat loss through radiation, much needing the field of high efficiency and heat radiation, owing to being subject to space, size and environmental restraint, the form accelerating forced convection cannot be adopted thermal exchange to be gone out, and when can not satisfy the demands by means of only thermal conduction, strengthening ir radiation heat radiation is first-selected solution.Because a lot of material of occurring in nature all has very high thermal radiation system, such as coating resin itself, but its thermal conductivity is very low, and very large with heat dissipating substrate thermal contact resistance, the effect accelerating the heat radiation of substrate ir radiation can not be realized.Therefore, the lifting of infrared heat radiation coating performance depends on high infrared emittance, high thermal conductivity and low interface resistance.
Often using high heat conductance inorganic materials as paint filler in traditional heat-dissipating coating, boron nitride and nano-carbon material (carbon nanotube, Graphene) all have very high thermal conductivity, and its powder body material is the important filler of thermal management materials.Especially carbon nanotube, wherein theoretical thermal conductivity is up to 5000 W/mK, and its specific surface area is huge, is described as material the most black in the world, only has 0.045% to the specific refractory power of light, and specific absorption is up to more than 99.5%, and radiation coefficient is close to 1.0 of perfect black body.Therefore nano-carbon material is used as the function that heat radiation filler can play its heat conducting and radiating and ir radiation heat radiation simultaneously, is the outstanding filler in high-performance heat sink material.But the surface-area huge due to nano-carbon material and one dimension or two-dirnentional structure cause nano-carbon material difficulties in dispersion in body material, and are difficult to obtain high volume content.And owing to being subject to the difference of thermal conduction mechanism, research finds that the interpolation of nano-carbon material is to the raising of thermal conductivity and not as so remarkable to the raising of specific conductivity, desired by people.Meanwhile, the boron nitride of micron order yardstick is a kind of conventional heat conductive filler, and its dispersing technology requires far below the requirement to nano-carbon material, and its large-size particle is more conducive to form effective passage of heat.But its infrared emittance is on the low side, the effect of multiple radiating mode cannot be given full play to.
Research finds, thermal conductive ceramic filler and nano-carbon material compound are added can significantly improve coating matrix thermal conductivity, significantly better than independent additive effect, shows a kind of multiple dimensioned collaborative enhancing phenomenon.But in this simple mixing interpolation pattern, because nano-carbon material and thermal conductive ceramic filler are that stochastic distribution contacts, and contact area is little, and both thermal contact resistances are very large.
