Benefits of technology

This patent describes a new kind of liquid made up of oil and water mixed together. This mixture is stable and doesn't foam too much, which makes it useful in a variety of applications such as metal-working or cleaning fluids.

Problems solved by technology

Other considerations include cost and environmental factors and worker safety issues due to, for example, misting or foaming during use.

example 1

[0049]Emulsifying properties and foam resistance were evaluated for four different commercially available sodium sulfonate (M, H, HL, and L) emulsifiers and an ethoxylated ether amine according to the present disclosure (Surfonic® PEA-25 emulsifier available from Huntsman Petrochemical LLC). The oil concentrates were prepared by adding each emulsifier at various dosages (5 wt. %, 8 wt. %, and 12 wt. % of emulsifier, based on the total weight of the oil concentrate) to a base oil (paraffin-base oil).

[0050]5.0 grams of the resulting oil concentrate and 95.0 grams of deionized water were then added to a graduated cylinder. The cylinder was stoppered, shook, and various properties were then measured. The results are given below in Table 1 through 3.

Abstract

The present disclosure provides a lubricating oil concentrate containing an ethoxylated ether amine and a base oil. The lubricating oil concentrate is capable of forming a stable, low foaming emulsion when added to an aqueous medium and may be useful in metalworking and cleaning fluids.

Description

FIELD OF THE INVENTION[0001]The present disclosure is directed to an ethoxylated ether amine useful in preparing water-miscible concentrates of lubricating oils, to such concentrates and to aqueous emulsions obtained therefrom.BACKGROUND INFORMATION[0002]Metalworking fluids are used throughout industry in a variety of metalworking processes such as rolling, stamping, drawing, pickling, cutting, extruding and forming of metal. The fluids act by cooling and lubricating the metal-tool interface while flushing the fines or chips of metal away from the work piece.[0003]Included among metalworking fluids are: straight oils, soluble oils, semi-synthetics and synthetics. Straight oils, also called “cutting” or “neat” oils, are made up of a base oil, such as a mineral (petroleum), animal, vegetable or synthetic oil. Soluble oils contain a base oil (e.g. about 30-85 weight percent of base oil) while semi-synthetics, which are similar to soluble oils, contain lesser amounts of base oil (e.g. a...
