摘要:
Water-based hydraulic fluids and metalworking lubricants are disclosed which are thickened with a polyether polyol having a molecular weight of about 1000 to about 75,000 modified with an alpha-olefin epoxide having about 12 to about 18 carbon atoms. Unexpectedly, synergistic thickening results from a combination of said polyether polyol with the components of a water-based hydraulic fluid or metalworking lubricant. The particularly effective components of the hydraulic fluid or metalworking lubricant are the phosphate ester and water-soluble amine corrosion inhibitor components. The hydraulic fluid and metalworking fluids of the invention also contain a water-soluble polyoxyethylated ester of an aliphatic acid and a monohydric or polyhydric aliphatic alcohol, either one or both said acid and said alcohol being polyoxyethylated, a sulfurized molybdenum or antimony compound and a metal deactivator as well as other adjuvants conventional in this art.
摘要:
Compositions containing a base lubricant, an antiwear amount of a polypropylene glycol and sulfur; and a solubility improving amount of a monohydric alcohol having from 5 to 30 carbon atoms are provided. These compositions are especially useful for metal working and cutting applications.
摘要:
Metalworking fluids containing diethanol disulfide in effective amounts to provide extreme pressure and anti-wear properties are disclosed. A preferred metalworking fluid is an aqueous solution of diethanol disulfide and water-soluble polyoxyalkylene glycols. Concentrates and use solutions are disclosed.
摘要:
A metalworking composition and an additive for a metalworking composition which imparts extreme pressure, antiwear, and corrosion-inhibiting properties to the metalworking composition. The additive comprises a phosphate ester and a sulphur compound. The composition comprises the additive used in an oil-based vehicle.
摘要:
A direct externally applied grinding, abrading and cutting aid for tools which includes a vehicle or carrier of a suitable matrix softer than the cutting material and which will readily adhere thereto without chipping while the tool is in motion. Dispersed within the matrix is a halogen salt or the like which includes hydrocarbons, chlorides, fluoborates, fluorides and various sulfides. These materials were selected on the basis that they sublime or decompose at temperatures below those that would metallurgically damage the metal workpiece. This aid is applied directly to the tool, as for example, to a coated abrasive and may be reapplied as often as is necessary, thus increasing both the life of the tool, its cutting rate, total metal removal, and its efficiency in addition to lowering the temperature of the material being cut. In addition, there is disclosed an automated system for maintaining the workpiece at a selected temperature through the controlled application of the aid.
摘要:
A stable free sulfur containing mineral oil is produced in a two-step process. The first step of the process comprises producing a sulfurized solubilizing oil by reacting a lubricant oil with elemental sulfur until the uncombined sulfur content is less than about 0.5%. The second step comprising dissolving in the oil a quantity of sulfur such that the final concentration of uncombined sulfur is less than 2.0%.
摘要:
Lubricant, particularly metal working, compositions which contain, in an amount sufficient to impart improved load carrying ability, sulfur and an organic hydroperoxide are provided.
摘要:
Liquid lubricant compositions are provided containing minor amounts of crystalline sulfur and a sulfurized fat as a dispersing agent. A process is also provided for preparing these compositions by heating amorphous sulfur to the crystalline hydrocarbon-soluble form and incorporating crystalline sulfur thus produced into liquid lubricant compositions in the presence of a dispersing agent comprising a sulfurized fat.
摘要:
A lubricant concentrate for use in metal processing comprises a sulfur compound such as a sulfurized olefin or sulfurized mineral oil and an ester prepared from a fatty acid having 12 to 40 carbon atoms or the dimer thereof or a polyalkenylsuccinic acid or anhydride and a hydroxyl-containing amine.
摘要:
Substantially oil-free aqueous industrial fluids comprise (A) up to as much as 99.9 percent by weight water, (B) at least one substantially water-insoluble functional additive stably dispersed in the water and (C) at least one substantially water-soluble liquid organic dispersing agent, said dispersing agent being capable of dispersing said functional additive in said fluid and are useful as liquids in a variety of industrial applications, such as hydraulic systems and metal shaping operations. Typically, these compositions also contain at least one water-soluble polymeric thickener and at least one corrosion inhibitor. Methods for preparing these fluids from concentrates are also disclosed.
