Definitions
- the present invention relates to a water-soluble metalworking fluid used in metal machining, and more particularly, to a composition of a water-soluble metalworking fluid produced by adding 5 to 70wt% of additives to 20 to 95wt% of distillation residues that is generated in production of biodiesel and used as lubricating base oil, and 0 to 40wt% of ion exchange water.
- Metalworking fluids are fluids which are used to assist metal machining operations. Traditional metal machining requires a machine tool, a cutting tool, a worked metal, and a machining fluid. Metalworking fluids were first used to increase the lifespan of an instrument for metal processing in the early 1900s.
- the original metalworking fluids were mainly formed of base oil refined from crude oil, and contained a large amount of polyaromatic hydrocarbons (PAHs) that are now known to be carcinogens due to non-development of refinement techniques. Workers can be exposed to these metalworking fluids via many forms and paths while in use, and the fluids may be a cause of cancer, non-malignant respiratory disease, dermatosis, microbial disease, etc. for the workers. Problems caused by oil mists and metalworking fluids were so significant for industrial health that they were even one of the priorities chosen by the U.S. Occupational Safety and Health Administration (OSHA) in 1996.
- PHAs polyaromatic hydrocarbons
- the metalworking fluids reduce friction and abrasion between a cutting tool and a worked metal, improve machining surface characteristics, reduce adhesion or melting of the surface, remove generated heat, prevent deformation caused by heat, and wash cut pieces, fine powder and residues.
- the metalworking fluids also prevent corrosion of machined surfaces, and cool the heated machined surfaces down so as to be more easily handled.
- the water-soluble metalworking fluids include cooling, prevention of welding between the cutting tool and the machined surfaces, prevention of abrasion at high temperature, and prevention of distortion caused by remaining heat.
- the water-soluble metalworking fluids are diluted with a water of about 60 to 85% just before using base oil that is more highly refined than cycloparaffin or paraffin-based oils used in a non-water-soluble environment. Since an available concentration of the water-soluble fluid ranges from 1 to 10%, characteristics of water that is used as a base material are important to performance of the fluid. Water is the best cooling agent due to high specific heat, good thermal conductivity and high latent heat. However, water rusts metal, and thus has less wettability and lubrication than oil.
- the water-soluble metalworking fluids include a rust inhibitor or a surfactant, thereby increasing lubrication.
- a recently developed additive can prevent corrosion for approximately several days to a week, which thus overcomes the poor rust inhibition and poor metal corrosion inhibition of the water-soluble metalworking fluids.
- the water-soluble metalworking fluids are nonflammable like water and non-sticky, so it is preferred by workers due to a clean work environment, but it is corruptible.
- the advantages of the water-soluble metalworking fluids are as follows. It can be used for fast cutting due to good cooling properties, and cleansing, thereby providing safe conditions for workers. Also, it is economical because of the use of water.
- the water-soluble metalworking fluids are classified into two types, which are an emulsion type which is translucent to an emulsion like a milky liquid when diluted with water, and a semi-synthetic and synthetic type.
- the milky white residue of the dilution indicates that an emulsion particle has a sufficient size to reflect transmitted light, and the clear dilution indicates that the particle is so small that the transmitted light mostly penetrates between the particles.
- Components and ratios of the conventional water-soluble metalworking fluids are listed below.
- the present invention is directed to developing a composition of a water-soluble metalworking fluid using a distillation residue generated in production of biodiesel as environmentally-friendly lubricating base oil.
- Biodiesel refers to an alternative energy processed from elemental lipid in vegetables and animals to have similar properties to gasoline, which can be used as a diesel equivalent or for diesel engines by being mixed with the gasoline.
- biodiesel refers to fatty acid methyl esters having a purity of 95% made from the transesterification between alcohols (generally, methanol) and vegetable oil (rice bran, waste cooking oil, soybean oil, rape oil, etc.). (Ministry of Commerce, Industry and Economy (MOCIE) Announcement No. 2000-57)
- the vegetable oil described above that is, a compound including a hydrophobic group insoluble in water, is generally composed of triglycerides represented as the following chemical structural formula.
- the vegetable oil is commonly characterized by the content of the fatty acid, and the length, content and saturation degree of the fatty acid become critical factors in determining physical and chemical characteristics of the oil.
- Animal oil is less useful than the vegetable oil, and only that made from a pig, a cow and a sheep among land animals, and herring and menhaden among fishes are considered as being commercially important.
- the animal oils are composed of saturated and unsaturated triglycerides like the vegetable oils, but include a wide distribution of fatty acids and some odd-numbered chain fatty acids, unlike the vegetable oils.
- the methyl ester from vegetable oil is mainly made of methyl oleate and methyl linoleate as main components, and exhibits excellent performance in machinability or detergency due to low viscosity (40 °C, 1.9 to 6.0 cSt.) and good lubrication when used instead of petroleum-based hydrocarbon lubricating base oil.
- the methyl ester from vegetable oil is made by the following processes.
- R, R' and R" are saturated or unsaturated hydrocarbons with alkyl groups.
- the methyl ester made from vegetable oil has various components and composition ratios depending on components of fatty acid in the vegetable oil and its ratio. Each of the methyl esters of the fatty acids listed in the following table is a component of the methyl ester made from vegetable oil.
- Vegetable oils capable of synthesizing the methyl esters from vegetable oil which may be used in the present invention are listed in the following table.
- Biodiesel may be mixed with gasoline and then used, or 100% pure biodiesel may be used.
- BD5 refers to a mixture of 95% gasoline and 5% biodiesel
- BD20 refers to a mixture including 20% biodiesel.
- Biodiesel attracts attention around the world as a future energy source in the aspects of recycling of waste resources, reduction of greenhouse gas (CO 2 ), and low emission of air pollutants.
- CO 2 greenhouse gas
- biodiesel is in exemplary use or is expanding its supply through model projects all over the world. Europe, which is very positive towards the use of alternative energy, first established a system for biodiesel.
- biodiesel can be used within a range satisfying the standard of general gasoline, and according to European Fuel Standard (EN590) taken effect in January, 2004, gasoline including 5% biodiesel or less (BD5) is recognized as general gasoline (satisfying the requirements of the EN14214 standard).
- EN590 European Fuel Standard
- BD5 gasoline including 5% biodiesel or less
- BD5 European Fuel Standard
- U.S. after National Biodiesel Board was founded in 1992, the Congress and EPA approved BD20 as a fuel for diesel engine vehicles in 1998, and President Bush declared the expansion of new recycled energy including biodiesel in 2001.
- the supply of biodiesel is increasing every year, and biodiesel is used in official vehicles of state governments and buses in addition to the U.S. Army, the U.S. Air Force, the Department of Energy and NASA.
- biodiesel In Korea, based on the announcement regarding a model supply project for biodiesel by MOCCC in May, 2002, the government performed the project for two years, and now is investigating market reaction to and problems with biodiesel.
- the major advantage of biodiesel is a reduction of smoke emitted from vehicles.
- biodiesel also emits the greenhouse gas CO 2 , when viewed from an overall cycle of the process (from production to consumption) it yields very low amounts of CO 2 , and emits relatively low amounts of sulfur oxide (Sox) and particulate matters (PMs).
- Biodiesel made from vegetable resources may be self-produced domestically, which is an advantage for energy security, and may reduce environmental pollution by recycling waste resources, such as waste cooking oil.
- biodiesel has several problems in substituting for conventional gasoline and volatile oils. Although biodiesel has to be mixed in a high ratio to reduce toxic chemicals in exhaust gases from vehicles, it may break down engines due to corrosion, and become denatured in long-term storage.
- methyl esters made from vegetable oil are required for methyl esters made from vegetable oil to be used as fuel oils for vehicles, and thus a separate vacuum distillation process is performed after the reaction of methyl esters.
- the vacuum distillation is performed at 2 to 3 torrs and a maximum temperature of 240 °C. After the vacuum distillation process, the distilled result is used as biodiesel fuel oil, and a distillation residue of about 10% is scrapped.
- Such a distillation residue generated in the production of biodiesel is a reactant of the vegetable oil with a structure of ester, and may be used as environmentally friendly lubricating base oil.
- An embodiment of the invention provides a composition of a water-soluble metalworking fluid which uses a distillation residue generated in production of biodiesel as lubricating oil, and is mixed with other additives.
- the additives include a surfactant, a lubricating additive, a metal corrosion inhibitor, a rust inhibitor, a pH booster, a defoamer, a preservative, a pigment, etc., of which all are less harmful to the environment, and do not include any one of components which have use restrictions, such as nitrite, formaldehyde, boron and derivatives thereof, and an extreme pressure agent.
- the present invention is directed to a composition of a water-soluble metalworking fluid produced by adding 5 to 70wt% of additives to 20 to 95wt% of distillation residues that is generated in production of biodiesel and used as lubricating base oil, and 0 to 40wt% of ion exchange water.
