Definitions

  • This invention relates to fire resistant (difficultly inflammable) fluids based on esters of phosphoric acid. More particularly, the invention relates to a fire resistant fluid based on a phosphoric acid ester or a mixture of phosphoric acid esters and containing a corrosion and hydrolysis inhibitor.
  • Hydraulic fluids based on phosphoric acid esters have been used for some time. They have characteristics suitable therefor; particularly, they are not easily inflammable, so that they are used above all in systems comprising closed hydraulic circuits such as hydraulic systems of turbines and of pressure casting, continuous casting and press plants. The use of such fluids is described for example in U.S. Patent 3,468,802 and U.S. Patent 3,723,315.
  • a fire resistant fluid comprising a phosphate ester and a corrosion or hydrolysis inhibiting amount of piperazine or a substituted piperazine.
  • the fluid of the invention may be useful as a lubricant, a hydraulic fluid, a transformer oil or for a variety of other purposes wherein a fire resistant fluid is required.
  • the problem underlying this invention is to develop a fire resistant fluid having improved characteristics compared to those of known fluids used in hydraulic systems, especially with regard to corrosion inhibition and/or hydrolytic stability.
  • a fire resistant fluid based on a phosphoric acid ester or a mixture of phosphoric acid esters and containing piperazine and/or at least one piperazine derivative as corrosion and/or hydrolysis inhibitor.
  • the proportion of piperazine or piperazine derivative in fluids according to the invention is in the range of 0.005 to 5% by weight and is preferably in the range of 0.01 to 0.5% by weight.
  • the phosphate esters used as the base for fire resistant fluids are mainly aryl esters of phosphoric acid.
  • the triaryl esters are particularly-preferred because they are clearly superior in regard to fire resistance but diaryl alkyl phosphate esters may also be employed.
  • the preferred triaryl phosphate esters include, inter alia, tricresyl phosphate ester, trixylyl phosphate ester, phenyl dicresyl phosphate ester, cresyl diphenyl phosphate ester and tri(isopropylphenyl) phosphate ester, di(isopropylphenyl) phenyl phosphate ester and isopropylphenyl diphenyl phosphate ester.
  • Diphenyl-2-ethylhexyl phosphate ester is an example of the diarylalkyl phosphate ester which may be used, although with a clear loss of fire resistance in the fluid. If greater fire resistance is required halogenated phosphate esters may be used, in particular chlorinated aryl esters which, however, have considerable other disadvantages (such as corrosion).
  • the corrosion and hydrolysis inhibitor may be piperazine itself or a substituted piperazine.
  • alkyl, aryl, alkaryl and aralkyl substituted piperazines may be used, and the substituent groups may themselves be substituted, for example, by halogene, hydroxy, alkoxy, amino, alkylamino or dialkylamino groups.
  • Other substituent groups on the piperazine ring may be hydroxy, hydroxyalkyl, alkoxy, alkoxyalkyl, alkoxyaryl, amino, aminoalkyl, alkylamino, dialkylamino, alkylaminoalkyl and dialkylamino alkyl.
  • the substitution may be made on the carbon or nitrogen atoms of the piperazine ring.
  • Preferred types of substituted piperazine are:
  • the fluid according to the invention may also include other additives when this is desirable for particular applications.
  • additives may be, for example, metal deactivators, antioxidants and antifoaming agents.
  • antioxidants are:
  • esters of thiodipropionic acid Dilaurylthiodipropionate ester.
  • antifoaming agents are silicones.
  • Esters A-E are mixtures of the following:
