。Generally, conductive composite powder is manufactured by kneading conductive powder and resin powder using a Panbury mixer or the like, and then freezing and pulverizing the mixture. However, the conductive composite powder obtained by such a method has the drawback that the resin powder is coated around the conductive powder particles, which reduces the conductivity of the conductive powder. This method was developed in order to eliminate the drawbacks of the conventional methods, and it is possible to produce a conductive composite powder for powder coatings through a rational, efficient, and simple process.

5 to 70% by weight of conductive powder such as carbon black of less than μm, and (c) naphthalene sulfonic acid-based surface activity 7f.
Mix 0.1 to 10% by weight of l+ and (d) 70 to 95% by weight of a solvent such as methanol, ethanol, toluene, methyl ethyl ketone, methyl isobutyl ketone ((a)
(c) + (d)'') and uniformly dissolved and dispersed in a wet process using a ball mill or the like to have an apparent specific gravity of 0.9 to 3.
Step (A) of preparing a suspension (a) with a viscosity of 1 to 100 centivoids, and after fluidization with hot air) resin powders such as polyethylene, butyral, phenol, epoxy, etc., and baraprene, silicone, with an average particle size of 1 to 500 μI. The method is characterized by comprising a step (B) of spraying the suspension (a) around the rubber powder and drying it, and a combination [(A) + (B)].

液（イ）の分散性が悪くなるので不可である。Therefore, the average particle size of the conductive powder (a) of graphite, gold, silver, copper, tin, nickel, etc. is in the range of 0.1 to 300μ,
The average particle size of the carbon black is less than 0.16 m;
If the average particle size is 0.1μ, it is usually difficult to obtain industrially except for carbon black, and the cost will be high, so it is not possible.If it exceeds 300DIIl, the dispersibility of the suspension (a) is This is not allowed as it will make things worse.

できない導電性粉末ができてしまうので不可である。(a) When limiting the quantity of conductive powder such as graphite, gold, silver, copper, tin, nickel, and carbon black, if the amount is less than 5% by weight, it is possible to impart conductivity and to maintain stability. This is not possible because a certain suspension (a) cannot be obtained and the conductive powder cannot be sufficiently coated around the resin powder, and if it exceeds 70% by weight, it is too thick and a stable suspension cannot be obtained. This is not possible because (a) cannot be obtained and conductive powder that cannot be coated is produced.

よびカチオン界面活性剤がある。Next, if the dispersant (c) is less than 0.1% by weight, the dispersing effect will be insufficient, and if it exceeds 10% by weight, it is not necessary from an economic point of view, and neither is acceptable. Moreover, preferably 1 to
3% by weight is used. As a surfactant used as a dispersant, naphthalene sulfonic acid/formaldehyde condensate (dinaphthyl methanesulfonate), etc. can be suitably used, such as "Demol NJ (trade name, manufactured by Kao Atlas Co., Ltd.).Others" There are anionic surfactants and cationic surfactants.
次に、懸濁分散液の分散媒である溶剤（ｄ）については

０重量％未満の場合は液の濃度が濃すぎて何れも不可で
ある。Next, regarding the solvent (d), which is the dispersion medium of the suspension dispersion liquid, if it exceeds 95% by weight, the concentration of the liquid is too thin;
If it is less than 0% by weight, the concentration of the liquid is too high and neither is possible.

ぎて、噴霧もうまく行かな（なる。Furthermore, if the apparent specific gravity of the suspension (a) is less than 0.9, the liquid is too thin and cannot be used; if it exceeds 3.0, spray coating will not be successful, and the stability of the liquid will deteriorate. Not possible. Similarly, if the viscosity is less than 1 centivoise, it will be too thin and the adhesion will be poor; if it exceeds 100 centivoise, the liquid will be too thick and spraying will not work.

μm, and if it exceeds 500 μm, it cannot be used as a powder coating because the paintability is poor, and if it is less than lu-, it is usually difficult to obtain and is disadvantageous from a practical point of view.
