。[Prior Art] Lubricants are indispensable for preventing seizing and reducing frictional resistance and wear in the sliding parts of machinery, but lubricants applied to sliding parts are generally coated in an oil-based base. Solid lubricants are known that contain activators, extreme pressure additives, viscosity modifiers, etc., and further contain fine particles having self-lubricating properties, such as molybdenum disulfide.

Therefore, it has been necessary to periodically replace the lubricant to minimize wear on the sliding parts.

Fracture occurs at
As the particles became finer, the particle distribution range expanded, causing changes over time, and colloidal stability was insufficient due to the large particle size.

超潤滑用スティックを提供することにある。The present invention has been made in view of the above-mentioned circumstances, and its purpose is to manufacture machinery, equipment, parts, etc., such as precision processing machines and food processing machines, where large amounts of lubricating oil cannot be used. To provide a super lubricating stick that can reduce frictional resistance and maintain super lubricity for a long time by just applying a small amount to the sliding parts of the stick.

Diamond particle clusters with a rounded shape of 0 angstrom or less (hereinafter referred to as ultrafine particles) are dispersed in a base material whose main component is a water-soluble or oil-soluble polymer substance and solidified.

性を維持するため潤滑性の低下が非常に少ない。[0008] Unlike existing diamond fine particles, rounded ultrafine particles with an average particle size of 100 angstroms or less do not have an abrasive mechanism, so they may damage the surface of the sliding part or cause wear. There is no. Furthermore, since the ultrafine particles are diamond, they are extremely hard and are less likely to break, and maintain colloidal properties in the lubricating layer for a long time, resulting in very little deterioration in lubricity.

It is a particle cluster that has been classified into particles of 0.00 angstroms or less and sized into a rounded particle shape. Therefore, the ultrafine particles themselves have excellent lubricity, which is almost the same as or better than that of fluororesin powder, and has both hardness and self-lubricating properties.

性が継続する。[0010] Therefore, a stick is made by dispersing such ultrafine particles in a base material mainly composed of water-soluble or oil-soluble polymer substances such as polyethylene glycol, stearic acid, paraffin, and various waxes. When applied to sliding parts, it dissolves well in oil, mineral oil, or water, forming a coating film with good dispersibility and exhibiting excellent lubricity. Moreover, in this case, since multiple layers of ultrafine particles exist on the real contact surface, the frictional resistance is lowered by the rolling action of each ultrafine particle, and lubricity continues for a long time.

It is a super lubricating stick.

The weight ratio is set to 0.01% or more, and if the ultrafine particle content is increased, the ultrafine particles become agglomerated and a wrapping effect occurs, so a weight ratio of about 1% is desirable.

A solidified stick with properties is obtained.

。When the solidified stick obtained in the above example was applied to the sliding surface of the bed of a lathe, the frictional resistance was reduced to less than half that of a commercially available lubricant. The time it takes to replenish has more than tripled. Furthermore, when the coating was applied to a traveler ring for spinning, thread breakage was eliminated and the thread breakage time was extended by more than 10 times compared to when no coating was applied.

The error for the 10 measurements was 0.2 μm at maximum, which was 1 μm when no coating was applied, and it was confirmed that the movement was smoother against slight movements.

This is because there are multiple layers of ultrafine particles, and the rolling action of each ultrafine particle lowers frictional resistance, resulting in continued lubricity for a long time.

Therefore, since the generation of frictional heat in sliding parts and meshing parts can be reduced, there is an effect that the durability of machines, equipment, etc. can be improved. Furthermore, the rolling action of individual ultrafine particles reduces frictional resistance and maintains lubricity for a long time, making it suitable for use in sliding parts of machinery where it is difficult to replenish or replace lubricant, improving reliability. effective.
