Abstract

Disclosed herein is a method for reducing the oxidative and biological degradation of a metalworking fluid comprising adding thereto at least one antioxidant and at least one biocide.

Claims (10)

1. A composition, comprising:

at least one metalworking fluid comprising a water in oil metalworking emulsion wherein the oil phase consists essentially of naphthenic mineral oil, an emulsifier for the naphthenic mineral oil,

0.25 wt. % of an antioxidant selected from the group consisting of butylated (30%) and octylated (24%) diphenylamine and butylated (45%) and octylated (19%) diphenylamine, and

0.25 wt. % of a 1,3,5-tris(2-hydroxyethyl)-S-triazine;

wherein the diphenylamine and the 1,3,5-tris(2-hydroxyethyl)-S-triazine are present in amounts sufficient to reduce biological degradation by delaying bacteria onset by at least 18 weeks following a 1 day incubation period in accordance with ASTM 3946.

2. A composition, comprising:

at least one metalworking fluid comprising a water in oil metalworking emulsion wherein the oil phase consists essentially of naphthenic mineral oil, an emulsifier for the naphthenic mineral oil,

0.25 wt. % of a nonylated diphenylamine, and

0.25 wt. % of a 1,3,5-tris(2-hydroxyethyl)-S-triazine;

wherein the nonylated diphenylamine and the 1,3,5-tris(2-hydroxyethyl)-S-triazine are present in amounts sufficient to reduce oxidative degradation by having a total acid number of about 0.6 after 312 minutes of aging in accordance with ASTM D943 and sufficient to reduce biological degradation by delaying bacteria onset by at least 18 weeks following a 1 day incubation period in accordance with ASTM 3946.
