摘要：

The　epoxy　silicone　resin　was　modified　using　zinc　powder　as　heat　conducting　filler.　Effect　of　zinc　powder　mass　fraction　on　the　thermal　conductivity　of　modified　epoxy　organosilicon　dry　film　coating　was　researched　and　the　effect　of　coating　thickness　on　the　thermal　conductivity　of　carbon　steel　was　analyzed.　The　results　showed　that　The　thermal　conductivity　of　silicone　coating　is　around　0.19　W/(m•K),　and　heat-resistant　temperature　is　above　200℃.　Thus,　the　coating　can　ensure　the　long-term　coating　work　in　the　low　temperature　flue　gas　waste　heat　recovery　heat　exchanger　surface　without　any　thermal　reaction.　Addition　of　zinc　powder　can　improve　the　thermal　conductivity　of　modified　epoxy　organosilicon　coating.　As　the　zinc　powder　content　is　25wt%,　the　thermal　conductivity　of　the　coating　material　can　increase　84%　to　0.35　W/(m•K).　Generally,　with　the　increase　of　coating　thickness,　the　thermal　conductivity　of　metal　matrix　composite　silicone　coating　decreases.　The　thermal　conductivity　of　uncoated　carbon　steel　was　47.59　W/(m•K),　and　the　thermal　conductivity　of　the　coated　carbon　steel　decreased　to　34.33　W/(m•K)　when　the　coating　thickness　was　200　μm.　©　2018,　Science　Press.　All　right　reserved.
