Claims
- 1. A coatable, stable grinding aid precursor composition comprising
- (a) a thermoset resin having a thermoplastic resin dispersed therein, said thermoplastic resin and said thermoset resin are present at a weight ratio sufficient to improve at least one of rheological and grinding efficiency effects of the grinding aid composition; and
- (b) a plurality of grinding aid particles dispersed in said thermoset resin; said grinding aid particles are present in said grinding aid composition in an amount effective to increase grinding efficiency.
- 2. A grinding aid precursor composition in accordance with claim 1 further comprising a dispersing agent.
- 3. A grinding aid precursor composition in accordance with claim 2 wherein said dispersing agent comprises sodium dioctyl sulfosuccinate.
- 4. A grinding aid precursor composition in accordance with claim 1 further comprising a thixotropic agent.
- 5. A grinding aid precursor composition in accordance with claim 1 further comprising a coupling agent.
- 6. Grinding aid precursor composition in accordance with claim 1 wherein said weight ratio is at least 0.1:1.0.
- 7. Grinding aid precursor composition in accordance with claim 1 wherein said weight ratio is at least 0.3:1.0.
- 8. Grinding aid precursor composition in accordance with claim 1 further comprising an organic diluent.
- 9. A grinding aid precursor composition in accordance with claim 1 further comprising water.
- 10. A grinding aid precursor composition in accordance with claim 1 wherein said thermosetting resin comprises an epoxy resin and a curing agent for the epoxy resin.
- 11. A grinding aid precursor composition in accordance with claim 10 wherein said epoxy resin is emulsified.
- 12. Grinding air precursor composition in accordance with claim 1 wherein said thermoplastic resin comprises low softening point nonpolar materials selected from the group consisting of:
- (a) aliphatic hydrocarbons; and
- (b) polymerized units of C.sub.7 and C.sub.9 inclusive aromatic monomers.
- 13. A grinding aid precursor composition in accordance with claim 1 wherein said grinding aid is selected from the group consisting of halide salts, halogenated polymers, and sulfur-containing compounds.
- 14. A grinding aid precursor composition in accordance with claim 13 wherein said halide salt is selected from the group consisting of KBF.sub.4, cryolite, and ammonium cryolite.
- 15. A grinding aid in accordance with claim 12 wherein the materials are anionic emulsified thermoplastic resins of (a) and (b).
