The flaky potassium titanate compounded in the dry lubricating coating composition of the present invention is a particle having a reinforcing effect on the lubricating coating. Greatly increase the coating strength. This reinforcing action enhances the wear resistance of the coating against repeated friction. Also, potassium titanate has heat resistance,
It is an inorganic material with excellent heat insulation properties. It does not lose its reinforcing effect even in a high temperature range, and its flake shape has a large effect of absorbing and relaxing internal stress accompanying heating of the coating. blistering, cracking, occurrence) of peeling preventing suppression, Ru enhance its heat stability. Contact name potassium flaky titanic acid, the specificity of the crystal structure, low hardness MiKakeue (Mohs hardness 2-3), because it coefficient of friction itself reasonably low, such as molybdenum disulfide solid While maintaining good lubricity (low friction coefficient) of the solid lubricant without substantially affecting the lubricating action of the lubricant, the compounded effect of the flaky potassium titanate improves the resistance as described above. It is possible to form a lubricating film having abrasion, heat stability and the like .

Regarding the shape and size of the flaky potassium titanate, if it is too coarse, the dispersibility and workability in the preparation of the coating material are poor. On the other hand, in the case of extremely fine particles, the reinforcement is a morphological feature as a flake. In addition to weakening the action,
Because of an increase in specific surface area and an increase in oil absorption (JIS K5101), the viscosity of the paint tends to increase significantly, which is not preferable. Also, when the thickness of the flake becomes large, the smoothness of the coating becomes poor, while when it is too thin, the mechanical strength becomes poor. From these points, those having a size of about 1 to 100 μm and a thickness of about 0.01 to 2 μm are preferably used. In particular,
As for the size, potassium titanate having a length of about 5 to 100 μm, a width of about 1 to 30 μm, and an aspect ratio (length / width) of about 3 or more is considered as a flake-shaped effect. It has excellent effects such as film strengthening and heat resistance.

For example, epoxy resin, phenol resin, polyester resin Melamine resin, urea resin, polyamide resin, polyamide imide resin, alkyd resin, furan resin, silicone resin and the like.

The mixing ratio of the thermosetting resin to the solid lubricant and the flaky potassium titanate cannot be strictly specified depending on the resin used, the material type of the solid lubricant, and the like. If the amount is too small, the lubricating effect cannot be sufficiently exerted.On the other hand, if the amount is too large, the coating becomes brittle, and on the other hand, for the flaky potassium titanate,
If the compounding ratio is too small, the effect of improving the wear resistance and heating stability of the coating film is insufficient, and if the compounding ratio is too large, the friction coefficient increases and the wear amount tends to increase, which is not preferable. From these facts, the solid lubricant is generally about 100 to 25 parts by weight per 100 parts by weight of the thermosetting resin.
It is appropriate that the blending composition range is 0 parts by weight and the flaky potassium titanate is about 5 to 60 parts by weight.

To have. Comparative Examples No. 13 and No. 14 contain a solid lubricant and flaky potassium titanate in a complex form.
In No. 13, the excess of flaky potassium titanate resulted in an increase in the coefficient of friction and a decrease in wear resistance.
