摘要:
A lubricant in the form of a water or oil insoluble solvent in oil emulsion is described where a base (soluble or dispersible in said oil-insoluble solvent or water) is present in the dispersed phase. These lubricants are beneficial in various applications such as internal combustion engines where the oil needs enough basicity to neutralize any inorganic acids generated by sulfur present in the fuel.

[PROBLEMS] To provide a biodegradable lubricating oil composition which has excellent biodegradability, a high viscosity index, a low pour point, a high flash point, being satisfactory with lubricity, oxidative stability, property of preventing the corrosion of iron and non-ferrous metals, and suitability for use with sealing materials.[MEANS FOR SOLVING THE PROBLEMS] A biodegradable lubricating oil composition comprising (A) a synthetic ester base oil comprising at least 50 mass % hindered ester of an aliphatic monocarboxylic acid with an aliphatic hindered polyol which has one or more quaternary carbon atoms per molecule and in which at least one of the quaternary carbon atoms has one to four methylol groups bonded thereto and (B) ingredients which are (a) 0.1 to 5.0 mass % phenolic antioxidant, (b) 0.01 to 2.0 mass % calcium sulfonate having a low base number, and (c) 0.01 to 1.0 mass % triazole compound, and has the degree of biodegradation of 60% or higher when examined by the test for the degree of microbial degradation of chemical substances according to the OECD Test Guideline 301C method.
摘要:
This invention relates to a composition that is a novel improvement of non-oil containing metal working fluids, also known as synthetic metal working fluids. The invention is a non-oil containing metalworking lubricant composition, having an engineered particle size of greater than 200 nanometers upon dilution. The expansive particle size results in a substantial increase in lubricity, suitable for the heavy-duty operations previously attainable only with oil-containing products. Additionally, this non-oil containing metalworking lubricant incorporates the best of the positive attributes of oil-containing products into its composition, including excellent corrosion inhibition and heavy-duty operation capable lubricity.
摘要:
Polymeric polyol ester additives for metal working applications are described that have lower pour points and improved solubility in API Group II and III basestocks. The polyol esters are made from tri and/or tetrahydric alcohols, a linear fatty monocarboxylic acid, a short dioic acid, and a alk(en)yl substituted succinic acid or its anhydride.
摘要:
A bromine/nitro moiety linked into the backbone of an ester or other compound over a wide range of occurrence rates provides antimicrobial, bio-resistant and fungal resistant properties for metal working fluids (MWF)s and other coatings. The moiety can be have the bromo and nitro groups linked to the same or different carbon atoms. The present invention also relates to urethanes, urea, amides, imides, carbonates, ethers, siloxanes, and many other types of linkages essential to MWF bases.
