Definitions
- the invention is a grease composition suitable for use under extreme pressure conditions comprising a base fluid, an alkali metal salt of a fatty acid and a tris-(2- chloroalkyl) ester of an oxyacid of phosphorus.
- the present invention relates to grease compositions suitabl for use under extreme pressure conditions.
- a grease composition suitable for use' under extreme pressure conditions comprises a base fluid, an alkali metal salt of a fatty acid and a tris-(Z-chlciroalkyl) ester of an oxyacidof phosphorus.
- the base fluid is suitably a hydrocarbon orprefeiably an ester which may be used as a synthetic lubricant base.
- esters of polyhydroxy compounds such as trimethylol propane tricapryla'te
- esters of polycarboxylic acids such as dinonyl sebacate.
- the alkali metal salt which is preferably the lithium salt, acts as a thickener and may be, for example, the palmitate, oleate, l2-hydroxystearate or preferably the stearate. It should comprise from 5 to 3 0% by weight, preferably 10-20% of the composition.
- Suitable tris-(2-chloroalkyl) esters of the oxyacids of phosphorus are tris-(2-chloroethyl) and tris- (2-chloropropyl) phosphite, and also the corresponding phosphate ester.
- the concentration of the ester in the composition should be in the range 0.1-5.0% by weight preferably 0.52%
- compositions may also contain conventional grease additives such as antioxidants and rust and corrosion inhibitors.
- the greases may be prepared by heating together the ester lubricant and alkali metal salt while stirring until a clear solution is obtained. The solution is cooled rapidly to give a gel which is worked to give the desired grease.
- the grease may also conveniently be prepared by generating the alkali metal salt in situ by addition of the fatty acid and saponifying it with alkali metal hydroxide, the removal of water.
- the ester of the oxyacid of phosphorus may be included at any stage of manuafacture but for convenience and to avoid undesirable interaction at high temperature they are conveniently included at the cold working stage.
- the cold working procedure involves milling or mixing at high shear rates to give a grease of smooth appearance.
- the grease formulations are further illustrated in the following examples.
- Example 2 The procedure of Example 1 was followed using the same proportions but tris-(Z-chloroethyl) phosphite (1 part) was milled in at the cold working stage.
- EXAMPLE 7 As for Example 1 substituting 2:2:626-tetrakis butylcyclohexanone-beta-propionate as the ester lubricant.
- EXAMPLE 8 As for Example 7 with the addition of tris-(2-chloroethyl) phosphite (1 part) as extreme pressure additive.
- chloropropyl) phosphite tris-(Z-chloroethyl) phosphate 1.
