Aiming　at　the　heat　dissipation　of　equipment,　and　based　on　ANSYS　finite　element　simulation　of　thermal　conductivity　of　coatings,　the　heat-dissipation　coating　filled　with　graphite　and　carbon　nanotubes　respectively,　which　integrates　heat　conduction　(high　thermal　conductivity)　and　radiation　(high　emissivity),　was　successfully　prepared　by　the　method　of　solution　mixing.　Meanwhile,　the　effects　of　filler　content,　type　and　shape　on　thermal　conductivity　and　emissivity　of　the　coating　were　also　investigated.　The　results　indicate　that　the　rising　tendency　between　the　simulated　data　by　FEM　and　experimental　value　is　consistent,　which　has　a　certain　directive　significance.　In　addition,　graphite　can　improve　the　thermal　conductivity　and　emissivity　of　the　coating　effectively;　however,　the　emissivity　decreases　when　the　content　exceeds　23.08%.　The　carbon　nanotubes　can　improve　the　thermal　conductivity　and　emissivity　simultaneously,　the　thermal　conductivity　is　2.3　times　that　of　pure　resin,　and　the　emissivity　is　up　to　0.91　at　the　2.0%　mass　fraction　of　carbon　nanotubes.　©　2017　Trans　Tech　Publications,　Switzerland.
