The invention discloses a functional nanometer heat dissipation
coating and a preparation method and application thereof. The functional nanometer heat dissipation
coating is prepared from, by weight,20-60 parts of
water soluble resin, 1-12 parts of a
water soluble curing agent, 0.1-2 parts of a
thickening agent, 40-70 parts of water, 0.1-0.5 part of a defoaming agent, 0.5-5 parts of a flatteningagent, 0.5-30 parts of auxiliaries and 0.5-5 parts of nanometer carbon materials. The heat dissipation
coating contains various nanometer raw materials, when the coating is used for coating the surface of a heat dissipation device, the heat dissipation efficiency of the heat dissipation device can be greatly improved, the temperature of an electronic device is lowered, and therefore the service life of the electronic device is prolonged; meanwhile, the coating further has the functions of resisting
corrosion, water, acid, soil, insulation and the like, no
antiseptic and other treatment needsto be performed on the heat dissipation device, and the coating has the advantages of being
environmentally friendly, safe, green and the like; the nanometer heat dissipation coating has the wide application prospect and the practical value in the field of electronic heat dissipation, and meanwhile the coating is simple in preparation technology, low in cost and suitable for large-scale production.
