Microscopically, their surfaces are uneven and not spherical, so they cannot be expected to have much of a ball bearing-like effect on the sliding surface. Based on the above, the present inventors used a solid lubricant to increase the friction coefficient of the contact surface to 4.
As a result of various searches to provide advanced boundary layer lubricants that reduce heat generation, we have found that

As described above, since the optically anisotropic microspheres used in the present invention are obtained as a vertical polymerization reaction laminate of pitches, they can be obtained in a fine powder form without any treatment such as mechanical crushing, and It is characterized by exhibiting the effects of the present invention because it is microscopically spherical.

Its occurrence can be recognized as a sphere. As this vertical polymerization reaction progresses, the spherules gradually grow, and the larger ones have a diameter of up to 100 microns.

記の通りである。Quinoline is used as a solvent to separate the optically anisotropic microspheres of the invention from the pitch matrix. That is, when quinoline is also added to the heat-treated pitches as described above, the optically anisotropic spherules are in a polymer state, so they do not dissolve in the quinoline and become a non-falling fraction. On the other hand, since the pitch matrix is a low-molecular substance, it dissolves in quinoline and becomes a soluble component. By removing this quinoline soluble content, the optically anisotropic microspheres used in the present invention can be obtained. The elemental analysis values of the optically anisotropic microspheres obtained as described above vary depending on the starting material, but are generally as follows.
炭 素：８２〜９２重量％
水素：４〜３
その他（窒素十酸素十硫黄）：１４〜５重量％また、こ
の小球体の比重は約１．５である。Carbon: 82 to 92% by weight Hydrogen: 4 to 3 Others (nitrogen, oxygen, and sulfur): 14 to 5% by weight The specific gravity of the small spheres is approximately 1.5.

。As mentioned above, the optically anisotropic microspheres are produced and grow as the condensation reaction of pitches progresses, so fine particles of any diameter can be obtained by selecting the heat treatment conditions. Furthermore, as a solid lubricant for boundary layer lubrication to reduce friction on contact surfaces, it is considered that the finer the particle size is, the better, although it depends on the roughness of the metal surface.

ろん市販の潤滑油を使用することができる。Therefore, the particle size of the optically anisotropic spherules to be obtained is determined by selecting optimal heat treatment conditions for the pitches. The conditions for heat treatment are generally at a temperature of 350~350℃.
The temperature is 500°C, and the treatment time is 10 to 120 minutes. Liquid lubricating oil (base oil) used in the present invention
Basically, any oil having lubricating properties may be used, and of course commercially available lubricating oils can be used.
前記光学的異方性小球体と該液状潤滑油とを混合するに
あたり、重要なことは小球体を液状潤滑油中に均一状に
分散させることである。In mixing the optically anisotropic small spheres and the liquid lubricating oil, what is important is to uniformly disperse the small spheres in the liquid lubricating oil.

滑油組成物が得られる。If these small spheres become non-uniform in the base oil, that is, aggregate or precipitate, the effect of solid boundary layer lubrication by the fine particles, which is the main objective of the present invention, is reduced. As mentioned above, since micron-sized particles tend to aggregate and precipitate in base oil, a well-dispersed lubricating oil composition can be obtained by using the following dispersant.

例により本発明をさらにくわしく説明する。Further, the ratio of the dispersant to the weight part of the liquid lubricating oil 10 to which the optically anisotropic small spheres have been added is 0.1 to 15 parts by weight, and preferably 0.3 to 8 parts by weight. In producing the lubricating oil composition in the present invention, the lubricating oil, the optically anisotropic spherules, and the dispersant may be mixed simultaneously, or any of the other components may be added to the lubricating oil, and then the other components may be added. Components may be added, but it goes without saying that these must ultimately be mixed uniformly. Hereinafter, the present invention will be explained in more detail with reference to Examples.
