Abstract
A water-based metalworking fluid is comprised of a polymeric boron species which includes at least B, N and H, together with a surfactant operable to provide an emulsion of the boron species with water. The polymeric boron species may be a polyborane or a borazine polymer and may be configured as a polyborane or borazine polymer backbone having side chains pendent thereupon. The side chains may include silicon and/or phosphorous. The silicon may be in the form of a silane or a siloxane species, including polymeric species. Disclosed are specific compositions as well as methods for using the compositions and methods for making the compositions.
Claims17
A metalworking fluid comprising a polymeric boron species which includes at least B, N, and H;
- water;
- and a surfactant operable to provide an emulsion of said polymeric boron species and said water.
The fluid of claim 47 wherein at least some of said side chains comprise a halogenated alkyl silane.
A water-based metalworking fluid comprising, on a weight basis:
- 1-15% of an alkanolamine;
- 0.1-5% of a polyol surfactant;
- 1-10% of a material selected from the group consisting of:
- polyaminoboranes, polyiminoboranes, borazine polymers, and combinations thereof;
- 10-30% of a corrosion inhibitor;
- 0.5-1.0% of a biocide;
- and
- the remainder water.
A method for making a metalworking fluid, said method comprising the steps of:
- providing a polymeric boron material which includes at least B, N and H;
- and
- mixing said polymeric boron compound with water and a surfactant so as to form an emulsified composition thereof.
