Abstract
A method of making an antifriction coating composition, comprising the steps of (A) combining (i) a solid lubricant, (ii) a solvent, (iii) a binder, and (iv) optionally, an additive; and (B) grinding the (i) solid lubricant in the solvent (ii) with a basket mill for sufficient time to form a dispersion of the ground (i) solid lubricant in the (ii) solvent, and wherein the binder (iii) and the optional additive (iv) are each independently combined with the solid lubricant (i) and solvent (ii) before, during, after, or a combination of two or more of before, during, and after, (B).
Claims25
A method of making an antifriction coating composition, comprising the steps of:
- (A) combining
- (i) a solid lubricant,
- (ii) a solvent,
- (iii) a binder, and
- (iv) optionally, an additive;
- and
- (B) grinding the (i) solid lubricant in the solvent (ii) with a basket mill for sufficient time to form a dispersion of the ground (i) solid lubricant in the (ii) solvent, and
- wherein the binder (iii) and the optional additive (iv) are each independently combined with the solid lubricant (i) and solvent (ii) before, during, after, or a combination of two or more of before, during, and after, (B).
(canceled)
(canceled)
The method according to any one of the preceding claims, further comprising modifying the grinding time to vary the average particle size and the particle size distribution of the solid lubricant.
(canceled)
(canceled)
The method according to any of the preceding claims, wherein the binder is a phenolic resin, epoxy resin, a silicone resin, or a mixture two or more of a phenolic resin, epoxy resin, and a silicone resin.
The method according to any of the preceding claims, wherein the solid lubricant is graphite, MoS2, PTFE, silicone, wax, a solid hydrocarbon wax, or a mixture of two or more of graphite, MoS2, PTFE, silicone, wax, and a solid hydrocarbon wax.
The method according to any one of the preceding claims, wherein the solvent is water, an alcohol comprising 1 to 4 carbon atoms, a ketone comprising 3 to 6 carbon atoms, an ester, a heterocyclic, an aliphatic or an aromatic compound.
(canceled)
The antifriction coating composition prepared by the method of any one of the preceding claims.
(canceled)
An antifriction coating composition, comprising:
- A dispersion of
- (i) a solid lubricant;
- (ii) a solvent,
- (iii) a binder, and
- (iv) optionally, an additive,
- wherein the solid lubricant has a particle size (d90) up to 75 μm and (d50) of up to 50 μm.
