を要していた。[Prior art and its problems] Conventionally, for bolts, nuts, bridges, steel towers, etc., surface treatment such as plating or chemical conversion treatment or paint containing aluminum flakes is mainly used for the purpose of corrosion resistance. Conventional paints containing flakes do not have sufficient weather resistance and need to be repainted after several years, and the cost is enormous. Also, when the bolts and nuts are plated, etc., they are not slippery enough, not only spending extra effort and time, but also the screw threads are crushed and the plating comes off, etc. There wasn't. Furthermore, for parts and members that require lubrication,
It was necessary to lubricate regularly, and maintenance was expensive.

少なくなり滑り性や耐食性が十分でなくなる。As the epoxy resin used in the present invention, bisphenol A type, bisphenol F type, novolac type, and aliphatic epoxy resin can be used. As the curing agent, amines, polyamines, polyamides, acid anhydrides can be used. Compounds, urea, phenol, melamine, polysulfide curing agents or their adducts, modified products, etc. can be used. The amount of the epoxy resin compounded in the coating composition is 10 to 10.
80% by weight is suitable, and preferably 45 to 65% by weight. If the amount of the epoxy resin compounded is less than 10% by weight, sufficient coating (adhesion) performance cannot be obtained, and the coating film may peel off or the metal flakes fall off during use. On the other hand, when it exceeds 80% by weight, the blending amount of other components becomes small and the slipperiness and corrosion resistance become insufficient.

は平均厚み０．０１〜３μｍ程度が好ましい。As the metal flakes, flakes of stainless steel, other corrosion-resistant iron alloys, titanium, tin, nickel, aluminum and the like can be used. Among them, stainless flakes (SUS304, SUS316L, other ferrite type, austenite type, two-phase type stainless steel, etc.) flakes are particularly preferable. The size of the flakes is preferably about 5 to 300 μm as an average particle diameter measured by a laser diffraction method, and particularly preferably 31 to 60 μm. If the average particle size is less than 5 μm, the production itself becomes difficult and the cost increases, and only the shape ratio (average particle size / average thickness) can be small, and the protective effect by the flake shape becomes weak. On the other hand, when it exceeds 300 μm,
It is not preferable because the hiding power is lowered and the flakes are broken or stick out from the coating film. The average thickness is preferably about 0.01 to 3 μm.

困難である。When stainless steel flakes are used, the amount of silicon contained is preferably 0.45 to 0.8% by weight. If it exceeds 0.8% by weight, the appearance after application becomes extremely whitish and the metallic appearance is lost, which is not preferable in terms of design. On the other hand, if less than 0.45% by weight, powdering
It becomes difficult to form flakes, and it is difficult to produce flakes having the above-mentioned shape.

30% by weight is suitable. If the content of the metal flakes is less than 3% by weight, the hiding property is insufficient and the effects such as corrosion resistance and weather resistance are poor. On the other hand, even if it exceeds 50% by weight, there is almost no further improvement in corrosion resistance and weather resistance, and the amount of resin is relatively small, which is not preferable in terms of adhesion.

One or two or more kinds may be contained in the coating composition in an amount of 1 to 40% by weight, preferably 5 to 30% by weight. If it is less than 1% by weight, lubricity is poor and sufficient slipperiness cannot be obtained. On the other hand, even if it exceeds 40% by weight, there is almost no further improvement in lubrication performance, which leads to an increase in cost, which is not preferable.
