The solid lubricant such as (graphite) has a commercially available particle size of, for example, 10 to 30 μm for the mineral MoS 2 and 5 for the PTFE.
It is relatively large, such as -10 μm, and when it is dissolved in a solvent at the same time as a matrix binder, it is likely to be dispersed unevenly in the liquid.

破壊を引き起こすおそれもある。Therefore, when a coated sliding member is manufactured by coating such a composition on a base material, the solid lubricant is locally absent on the sliding surface, and the local frictional force is increased. It also serves as the starting point for wear and peeling. Thus, the non-uniform dispersion of the solid lubricant not only impairs the wear characteristics and the seizure characteristics, but also the friction characteristics do not have low friction relative to the blending ratio of the solid lubricant, and these characteristics vary. . And, in the worst case, there is a possibility that the coat sliding member is broken.

い。Further, when a molded sliding member is manufactured using such a composition, when an external force such as bending stress or tensile stress is applied, a solid lubricant which is non-uniformly dispersed in the molded sliding member. There is a risk that stress concentration may occur in the material and the molding sliding part agent may be destroyed. However, although means for reducing the particle size of the solid lubricant in the coated sliding member or the molded sliding member as much as possible is conceivable, a sand mill, a roll mill, a homogenizer, etc. are used to reduce the particle size of the solid lubricant. However, although the minerals MoS 2 , PTFE, C (graphite) and the like become about 1 to 4 μm, they cannot be sufficiently dispersed in the solvent even with the binder.

That is, in the sliding member obtained by dispersing the organic molybdenum compound in the binder, Mo in the molecule of the organic molybdenum compound and S in the molecule on the sliding surface are activated by heat during sliding, MoS 2 is produced by the intermolecular reaction. Since the generated MoS 2 adheres to the sliding member and the surface of the mating member, the frictional force is reduced and the coefficient of friction is lowered, and along with this, the wear resistance and the seizure surface pressure are also improved. In particular, in the lubricating oil, S in the lubricating oil also participates in the generation of MoS 2 and the sliding characteristics of the sliding member are further improved.

期の摺動特性が十分でない。However, the present inventors have found that, in the case of a sliding member in which only an organic molybdenum compound is mixed in the binder, the starting temperature is relatively low and the lubricating oil temperature is low (about 40 to 50) at the initial stage of sliding. It was discovered that Mo in the molecule of the organic molybdenum compound and S in the same molecule or S in the lubricating oil are hard to be activated, and MoS 2 is less likely to be generated by the intermolecular reaction. Therefore, in the sliding member in which only the organic molybdenum compound is mixed in the binder, the sliding characteristics at the initial sliding stage are not sufficient.

It is preferably 1 to 30 wt% in the molded product, and the total amount when both the solid lubricant and the organic molybdenum compound are mixed is at most 60.01 wt% or less in the coating film.
It is preferably less than 30.01 wt% in the molded product. When the organic molybdenum compound is less than 0.01 wt% and the solid lubricant is less than 1 wt%, the above lubricant is less likely to exist on the sliding surface, and the binder serving as a matrix easily controls the sliding surface, resulting in low friction. However, the shearing force on the sliding surface is large and seizure occurs early. On the other hand, if the content of the organic molybdenum compound and the solid lubricant exceeds the above-mentioned ratio, the strength of the binder serving as the matrix will be remarkably lowered and the wear characteristics will be deteriorated. As a result, since the sliding surface is positively worn, the roughness becomes large, resulting in an increase in the coefficient of friction and a decrease in the seizure surface pressure.

ことができる。The composition for a sliding member of the present invention can be manufactured into a coated sliding member or a molded sliding member. When manufacturing a coated sliding member, a heat-resistant synthetic resin is dissolved in a solvent, an organic molybdenum compound and a solid lubricant are simultaneously mixed in the solution to obtain a composition, and the composition is coated on a base material and coated. The layer can be heat cured. Further, in the case of manufacturing a molded sliding member, it can be manufactured by simultaneously mixing an organic molybdenum compound and a solid lubricant into the solution at the time of injection molding to obtain a composition, and molding the composition into a predetermined shape. .

In the sliding member thus obtained, the sliding characteristics of the solid lubricant are obtained at the initial sliding stage when the starting temperature is relatively low or the lubricating oil temperature is low (less than about 40 to 50 ° C.). After reaching the MoS 2 generation temperature of 40 to 50 ° C., improvement in sliding characteristics can be obtained by the organic molybdenum compound.

Further, the friction coefficient, the amount of wear (μm) and the seizure surface pressure (MPa) of each of the obtained molded sliding members are measured.

And S in the same molecule or S in the lubricating oil are activated by heat during sliding, and MoS 2 is produced by an intermolecular reaction.

Therefore, M
It can be seen that after reaching the oS 2 generation temperature, the sliding characteristics can be improved by the organic molybdenum compound.

The results are also shown in Tables 4-6. It can be seen from Tables 4 to 6 that the same results as those of the molded sliding member can be obtained with the coated sliding member. It is also expected that the coated sliding members of Examples 20 to 36 are unlikely to break.

ることができる。As described above in detail, in the composition for a sliding member of the present invention, since the organic molybdenum compound and the solid lubricant are dispersed in the binder made of the heat resistant synthetic resin, it is excellent from the initial sliding stage. It is possible to manufacture a sliding member that reliably exhibits wear characteristics, seizure characteristics, and friction characteristics, and is less likely to break.
