摘要:
Combinations of carboxylic solubilizers, made by reaction of an acylating agent with an N-(hydroxyl-substituted hydrocarbyl) amine and surfactants are useful in incorporating oil-soluble, water-insoluble functional additives into aqueous systems. Typical solubilizers are made by reacting an alkyl-substituted succinic anhydride containing about 12 to about 500 carbon atoms with an alkanol amine such as diethyl ethanol amine. Typical surfactants are non-ionic hydrophilic surfactants such as ethoxylated phenols and ionic surfactants of both the anionic and cationic type. Typical functional additives are anti-wear, extreme pressure and load-carrying agents such as dithiophosphates. The aqueous systems formed with the aid of such combinations are useful, for example, as water-based hydraulic fluids.
摘要:
Aqueous compositions having a viscosity of at least 10 centistokes at 40.degree. C. which contain up to about 80 percent by weight of water, at least 0.1 percent by weight of an acidic lubricity agent and an effective amount of an anti-wear additive which is the combination of a nitroaromatic compound component and a hydroxyl substituted aromatic acid component exhibit enhanced anti-wear and lubricity properties.

摘要:
A lubricant composition comprising water, graphite, an organic thickener, sodium molybdate, and sodium pentaborate. Other additives are sodium bicarbonate, ethylene glycol, or mica. The composition is effective in the hot forging of metals, is virtually non-flammable, and generates very little atmospheric pollution during use.
摘要:
An emulsifiable concentrate for use in metal processing, especially in can forming, comprises an ester prepared from a polyalkenylsuccinic acid or anhydride, and a hydroxyl-containing amine. It is critical to the invention with respect to can forming that the acid or anhydride contain, in addition to its basic carbon length, a chain derived from an olefin having from 16 to 28 carbon atoms.
摘要:
A coating consisting essentially of 0.5% to 50%, preferably 2% to 20%, by volume, polyethylene oxide and about 6% to 30% a dispersion agent selected from the group consisting of propylene glycol, glycerol, ethylene glycol, polypropylene glycol, diethylene glycol, triethylene glycol and hexylene glycol, with the ratio of polyethylene oxide-to-dispersion agent, by volume, being no greater than 2:1 and preferably 1:3. The remainder being essentially water. The coating is useful as a lubricant to facilitate pulling plastic-sheathed cable through a conduit, drawing wire through a die and mounting a tire on a rim. The coating is an emollient for wood and useful in metalworking to inhibit or otherwise control oxidation, and as an annealing and normalizing agent.
摘要:
Amino-amides obtained by the reaction of polymeric fatty acids with poly(oxyethylene) diamines are readily compatible with water in all proportions and form clear, aqueous solutions which have excellent lubricating properties.
摘要:
An alcohol water solution of poly(ethylene oxide) having a molecular weight of about 4 million makes an extremely effective lubricant for applying to wire or cables which are to be pulled through conduits or raceways.
