Definitions
- the invention relates to a method for improving the air release of a lubricating oil.
- Lubricating oils are used to protect and lubricate surfaces in contact, and may also be used to transmit power. It is known that air entrainment can reduce the efficacy of lubricating oils. Air entrainment is a phenomenon wherein air bubbles (typically having a diameter of less than 1mm) are dispersed throughout the lubricating oil. Entrained air can be distinguished from free air (a pocket of air trapped in part of the system) , from dissolved air (lubricating oils may contain between 6 and 12 percent by volume of dissolved air) and from foam (air bubbles typically greater than 1mm in diameter that congregate on the surface of the oil) . Air
- the air entrainment properties of a lubricating oil are typically measured using the ASTM D3427 air release test. This test measures the time needed for air
- the present inventors have sought to improve the air entrainment properties of lubricating oils .
- the invention provides a method for improving the air release of a lubricating oil as measured by ASTM D3427, said method comprising mixing an additive into the lubricating oil using a high shear mixer; wherein the additive is an alkyl acrylate polymer.
- Such alkyl acrylate polymers have been previously used as anti-foam additives. Air release times are typically considered to get worse with the addition of additives, especially anti-foams such as silicone oils. This is explained by Duncanson in "Properties on Foam in Lubricating Oils", pages 9-13, May 2003 Lubrication Engineering, Journal of the Society of Tribologists and Lubrication Engineers.
- the present invention provides a method for improving the air release of a lubricating oil as measured by ASTM D3427.
- compressed air is blown through the lubricating oil, which has been heated to a temperature of 50°C. After the air flow is stopped, the time required for the air entrained in the oil to reduce in volume to 0.2% is recorded as the air release time.
- a desirable air release value is typically less than 3 minutes, preferably less than 60 seconds and most preferably less than 20 seconds.
- the air release is improved as compared to air release achieved using the lubricating oil wherein the additive has not been mixed with the lubricating oil using a high shear mixer.
- the inventors have found useful reductions in air release times when carrying out the method of the invention.
- the lubricating oil comprises a base oil component, which may be a blend of several base oils.
- the base oils in the base oil component may be any conventional base oils chosen from Groups I, II, III, IV or V of the API (American Petroleum Institute) base oil categories.
- the base oil component comprises a GTL base oil, and more preferably the base oil component comprises at least 75wt% of a GTL base oil based upon the weight of the base oil component.
- GTL base oils are synthesised by the Fischer-Tropsch method of converting natural gas to liquid fuel. They have a very low sulphur content and aromatic content compared with mineral oil base oils refined from crude oil and have a very high paraffin constituent ratio.
- the lubricating oil suitably comprises additives.
- the amount of additives is less than 10wt% based upon the weight of the lubricating oil, more preferably less than 5wt%, most preferably less than 2.5wt%.
- the additives may include antioxidants, antiwear additives, demulsifiers , emulsifiers, rust and corrosion inhibitors, VI improvers and/or friction modifiers.
- the lubricating oil has a kinematic viscosity in the range of from 5 to 220cSt at 40°C, more preferably of from 10 to 200cSt, most preferably of from 20 to lOOcSt.
- the kinematic viscosity is suitably measured using ASTM D445 (ASTM D7042) .
- the lubricating oil is formulated for use a hydraulic fluid.
- Hydraulic fluids are used in many different types of hydraulic machinery and are used not only to lubricate the machinery but also to transmit pressure. Air
- an alkyl acrylate polymer additive is mixed into the lubricating oil.
- Suitable alkyl acrylate polymers are disclosed in, for example, US3166508.
- the molecular weight of the polymer is suitably less than 10,000, preferably less than 7,500 and more preferably less than 5,000.
- the alkyl acrylate polymer may be a homopolymer of an alkyl acrylate having at least 3 but less than 7 carbon atoms in the alkyl radical.
- the alkyl acrylate polymer may be a copolymer of at least two different alkyl acrylates in which the alkyl radical has from 1 to 18 carbon atoms and in which the average number of carbon atoms in the alkyl radicals of the copolymer molecular is at least 3 but less than 7 on a molar basis.
- the preferred amount of alkyl acrylate polymer will be a balance between using enough to achieve the desired improvement in air release properties and avoiding unnecessary expense by using too much alkyl acrylate polymer.
- the alkyl acrylate polymer additive is mixed into the lubricating oil using a high shear mixer.
- high shear mixer is well-known to persons skilled in the art.
- a rotating impeller or high-speed rotor creates flow and shear within the liquid that is mixed.
- the rotor will turn within a stationary component known as a stator.
- the additive is mixed into the lubricating oil at a rate of at least 400rpm. The rate is preferably at least 600rpm and more preferably at least 800rpm.
- the mixing is for at least 10 minutes, more preferably at least 30 minutes, and most preferably at least 60 minutes.
- Table 1 gives the amounts of each base oil (in weight % based upon the total weight of the blend) present in each blend.
- the blends in Table 1 are all ISO 46.
