The invention relates to a high-electric-
conductivity heavy-anticorrosion wave-absorbing
powder paint which is prepared from the following raw materials in parts by weight: 450-500 parts of
epoxy resin, 50-100 parts of curing agent, 50-100 parts of conductive
pigment, 200-250 parts of conductive filler and 30-50 parts of assistant. The preparation method of the high-electric-
conductivity heavy-anticorrosion wave-absorbing
powder paint comprises the following steps: adding the materials into a high-speed mixer; after carrying out
dry mixing, adding the mixture into an extruder, and melting, mixing, cooling and pelleting at the
extrusion temperature of 80-90 DEG C; and pulverizing with a
pulverizer, grading, screening and packaging to obtain the finished
powder paint product. The invention has the characteristic of high electric
conductivity, has an absorption action on certain electromagnetic
waves, can be used as a preferred
coating for
electromagnetic shielding, and is applied to thefields of frequency converter shells, micro-current and light-current component shells and the like. In addition, the invention has excellent anticorrosion property and favorable electric conductivity (105
ohm), and the conducting power is almost approximate to that of a metallic conductor; and thus, the high-electric-conductivity heavy-anticorrosion wave-absorbing powder paint is an ideal antistatic
coating, and can ensure safety in the aspects of
fire resistance and explosion resistance.
