Definitions

• ABSTRACT Lubricating oil composition comprising from about 60 to 90 percent of a mineral oil, from about 5 to 30 percent of a vegetable oil or a fatty acid and from about 3 to 15 percent of a chlorinated paraffin containing greater than 40 percent chlorine.
• drawing oil act as a lubricant between the metal being shaped and the die to which the material is being conformed.
• Another important property of the drawing oil is that it enhance or improve the surface of the finished product or leave it in a condition which facilitates further treatment without causing new problems in the manufacture of the desired product.
• the drawing fluid should give good protection to the metal being worked against rust and should be easily removed in an alkaline and/or solvent washing bath.
• Drawing oils are used for the shaping of various metals such as carbon steels, low-alloy steels an stainless steels as well as for the forming of non-ferrous metals including copper, aluminum, zinc and nickel.
• the lubricant of the invention comprises a major portion of a mineral oil of suitable viscosity, from about 5 to 30 weight percent of an additive from the class consisting of vegetable oils and fatty acids and from about 3 to l5 weight percent of a chlorinated paraffin containing greater than 40 percent chlorule.
• the lubricating oil composition of the invention comprises from about 60 to 90 weight percent of a mineral oil having a viscosity in centistokes at 50C. from about 250 to 600, from about 5 to 30 weight percent of an additive from the class consisting of vegetable oils and a fatty acid having from about 10 to 35 carbon atoms and from about 3 to weight percent of a chlorinated paraffin containing greater than 40 up to about 80 percent of chlorine.
• the mineral oil component of the lubricant of the invention is obtained from a liquid top residue or a residual oil. This fraction is refined or distilled to remove any asphalt or waxy paraffins .to yield a high viscosity oil commonly referred to as a bright stock.
• Crude oils of certain origins may be directly refined or distilled to yield a bright stock or a cylinder oil which is suitable as a base oil for the lubricant of the invention.
• the base mineral oil of the invention is characterized by having a viscosity at 50C. in the range from about 250 to 600 centistokes and at 100C. from about 20 to centistokes.
• the preferred base oil has a viscosity at 50C. from about 250 to 350 centistokes and at 100C from about 20 to 45 centistokes.
• the density of the base oil is from 0.90 to 0.960 grams per ml. at 15C. and the open cup flash point is at least 330 C.
• the base oil comprises from 60 to 90 weight percent of the lubricant of the invention with the preferred concentration of the base oil being from about 70 to weight percent.
• the second essential component of the lubricant of the invention is selected from the class consisting of vegetable oils and fatty acids.
• suitable vegetable oils include rapeseed oil, palm nut oil, linseed oil, coconut oil, hempseed oil and sunflower seed oil. Rapeseed oil, coconut oil and palm nut oil are the preferred vegetable oils for formulating the lubricant of the invention.
• the fatty acid additive which can be employed encompasses the fatty acids which are obtained by known methods from vegetable oils and include mixtures of fatty acids such as is obtained in the fat splitting of vegetable oils. These mixtures are often suitable for direct use in the lubricant of the invention without further refining.
• the fatty acids which are suitable contain from 10 to 35 carbon atoms with a preferred members being those containing from 10 to 25 carbon atoms.
• the fatty acid can be a synthetic fatty acid or synthetic fatty acid mixture obtained synthetically rather than from natural sources. Examples of suitable and preferred fatty acids include stearic acid, palmitic acid, myristic acid, linolenic acid, linoleic acid, oleic acid and erucic acid.
• Another essential component of the lubricant of the invention is a halogenated hydrocarbon or, more particularly, a chlorinated paraffin.
• This additive consists of a paraffin base in which the paraffin has from 6 to 12 carbon atoms which has been chlorinated until the finished chlorinated paraffin contains greater than 40 percent and up to percent chlorine.
• concentration of the chlorine in the chlorinated paraffin is critical since the lubricant of the invention is not effective for the purposes intended when the chlorinated paraffin component contains less than 40 percent chlorine.
• a highly effective chlorinated paraffin which is commercially available contains about 54 percent chlorine and has a viscosity of about 8,000 centipoises at 20C.
• the chlorinated paraffin component of the lubricant of the invention is employed at a concentration from about 3 to about 15 weight percent of the lubricating oil composition.
• a preferred concentration of this component is from about 5 to 10 weight percent.
• EXAMPLE 1 In a heatable laboratory vessel fitted with a stirrer, the following items were mixed with constant stirring (about 20 rpm) at 50C, the total weight of the mixture at the start being 50 kg; 75 weight by weight of a dewaxed, deasphalted, refined and high-viscosity bright stock having a specific gravity at 15C. of 0.912, a flash point (COC) of at least 282C, a pour point of -15C EXAMPLE II EXAMPLE III The components described in the previous Examples were mixed in the following proportions; 70 percent by weight bright stock, 20 percent by weight olein, and percent by weight chlorinated praffin. The properties of the formulation are also given in Table I.
• the high performance drawing oils produced in the Examples were tested in the deep-drawing of motor vehicle or car body parts and other metal objects (eg wheelbarrow boxes).
• the material (St 14,05)* to be drawn was in the form of a sheet 1.25 mm thick X 1270 mm X 950 mm.
• normal drawing oils such as low viscosity mineral oils boric acid, mineral oil graphite or soap boric acid
• the same quantity of the new drawing oil could process from the same number to one and a half times the number of parts.
• the results showed a. better rust protection for parts stored inside,
• Example 3 Practical use showed the formulation used in Example 3 to be the best. The reasons for this are its better ageing characteristics, the film strength and lubricity of the bright stock and the higher content of chlorinated paraffin.
• a lubricating oil composition comprising from about 60 to 90 weight percent of a mineral oil having a viscosity of 50C. in the range of about 250 to 600 centistokes, from about 5 to 30 weight percent of an additive from the class consisting of vegetable oils and from about 3 to 15 weight percent of a chlorinated paraffin containing greater than 40 up to percent chlorine.
• a lubricating oil composition according to claim. 11 in which the paraffin portion of said chlorinated paraffin is derived from a paraffin having from 6 to 12 carbon atoms.
• a lubricating oil composition according to claim 1 in which said vegetable oil is rapeseed oil in a concentration of about 20 weight percent and said chlorinated paraffin contains about 54 percent chlorine and is employed at a concentration of about 10 weight percent.
