Abstract
A lubricant composition for treating non-ferrous metals and alloys is provided. In particular, the composition is used to treat metal substrates when the substrates are subjected to various metal working processes. The composition includes an emulsified ester that is combined with non-ferrous lubricating materials. The emulsified ester makes the lubricant water dispersible and therefore easily removable from the metal substrates after treatment. The composition of the present invention is extremely durable, biodegradable and environmentally safe.
Claims26
A composition for lubricating non-ferrous metallic materials in a metal working process comprising a stable emulsion containing an ester solvent, a lubricant for the non-ferrous metal and at least one emulsifier, said at least one emulsifier comprising a water dispersible emulsifier, said ester solvent containing a dialkyl ester, said ester solvent being present in said composition in an amount sufficient to make said composition water dispersible, said composition having a pH of up to about 7.0.
A composition used to lubricate non-ferrous metallic materials during metal processes, said composition being biodegradeable and removable from said metallic materials using only water, said composition having a pH of up to about 7.0 and comprising a stable emulsion including:
- a lubricant being present within said composition in an amount from about 40 percent to about 80 percent by weight;
- an ester solvent blended with said lubricant, said ester solvent comprising at least one dialkyl ester, said ester being present within said composition in an amount from about 3 percent to about 20 percent by weight;
- and
- a blend of emulsifiers, said emulsifiers comprising a water dispersible emulsifier and an anionic or nonionic emulsifier.
An emulsified composition used for treating non-ferrous metallic materials during metal working processes, said composition being biodegradable and water dispersible, said lubricating composition comprising:
- an ester solvent, said solvent comprising a mixture of dimethyl esters;
- an initially water insoluble lubricant, said lubricant being blended with said ester solvent;
- and
- a blend of emulsifiers for emulsifying said ester solvent and lubricant mixture, said blend of emulsifiers containing an ethoxylated castor oil and an amine salt condensate of a sulfonic acid.
A process for working non-ferrous metals, said process comprising the steps of:
- supplying a non-ferrous metal substrate;
- contacting said non-ferrous metal substrate with a lubricating composition, said composition having a pH of up to about 7.0 and comprising a stable emulsion containing an ester solvent, a lubricant for the non-ferrous metal, a water dispersible emulsifier, and an anionic or nonionic emulsifier, said ester solvent containing a dialkyl ester, said ester solvent being present in said composition in an amount sufficient to make said composition water dispersible;
- and
- working said lubricated non-ferrous metal substrate in order to modify the shape of said substrate.
A composition for lubricating non-ferrous metallic materials in a metal working process comprising a stable emulsion containing an ester solvent and a lubricant for the non-ferrous metal, said lubricant comprising butyl stearate, said ester solvent containing a dialkyl ester, said ester solvent being present in said composition in an amount sufficient to make said composition water dispersible.
