The invention discloses a high-heat-dissipation insulating
composite coating used for
supercapacitor shells. The high-heat-dissipation insulating
composite coating used for
supercapacitor shells is prepared from, by
mass, 60 to 80 parts of
epoxy resin, 20 to 35 parts of
alkyd resin, 5 to 20 parts of liquid phenyl
siloxane rubber, 3 to 6 parts of thiosemicarbazide, 40 to 60 parts of a
nitride, 4 to 5 parts of tetrabutyl
titanate, 2 to 5 parts of TTS, 5 to 7 parts of
polydimethylsiloxane, 2 to 5 parts of a curing agent, and an appropriate amount of a
solvent. The formula composition of the high-heat-dissipation insulating
composite coating is reasonable; the raw materials are safe and easily available; the high-heat-dissipation insulating composite
coating is prepared via steps such as heating, mixing, ultrasonic treatment, and
grinding; the dispersibility of the raw materials is excellent; the obtained high-heat-dissipation insulating composite
coating is uniform and flat; the heat dissipation performance and insulating properties of the high-heat-dissipation insulating composite
coating are improved greatly via modification treatment of inorganic
filling materials; the
adhesive force of the high-heat-dissipation insulating composite coating is high; the high-heat-dissipation insulating composite coating possesses excellent
flame resistance,
wear resistance, and
weather resistance, and is capable of improving application safety and prolonging the service life of capacitors obviously.
