Description

Eco-friendly water-soluble cutting oil composition and its manufacturing method}

The present invention relates to an eco-friendly water-soluble cutting oil composition and a method of manufacturing the same, and more particularly, an eco-friendly water-soluble cutting oil that replaces a preservative component material, which is a harmful component of conventional cutting oil, with an environmentally friendly material and replaces fatty acids, a substance that causes decay. It relates to a composition and a method of manufacturing the same.

The present invention relates to a composition of eco-friendly (water) cutting oil and a method for manufacturing the same, and in more detail, it is introduced from air (oxygen) when the equipment is stopped for a long period of time during cutting of mechanical parts equipment and supplied to the inside of the (water) cutting oil. It is done. At this time, the (water) cutting oil does not have an oxygen barrier, and the decay of fatty acids begins to proceed in a closed space at an appropriate temperature of about 25°C. The fatty acid contained in (water) cutting oil proceeds at a very high speed according to the pH value, and provides a nutrient source for microorganisms that bacteria and fungi can inhabit. When this decay begins, skin cancer, bladder cancer, gastric cancer and respiratory disease may occur due to inhalation of workers from the decayed odor.

In general, there are three ways to substitute eco-friendly antiseptic disinfectants, and all of them must meet the requirements in the development of (water) cutting oil. If the requirements are met, there will be a lot of difference from the existing composition and the composition (%) content will change, so the following characteristics must be maintained.

Cutting oil basically has the basic concept of lubrication and acts to reduce the frictional heat of mechanical equipment through the effect of cooling, and makes the mechanical movement smooth, reducing the cost burden and reducing the cost by using the concepts of fluid, fluid lubrication, and boundary lubrication. )The basic concept of protecting against wear by withstanding the weight (load) of the load by using cutting oil must be observed.

Classification according to the characteristics of the flow is movement (time required), uniformity, viscosity, and compressibility. There are flows made inside and outside the surface, and the fluid is said to be a physical property that represents the properties of the flow. Lubrication refers to the action of the lubricant by reducing friction and wear.

It is divided into boundary lubrication and fluid lubrication, depending on the state in which the lubricant (usually oil) is between the two sides. When the film of oil between the two surfaces is very thin and partially in contact with solids, it is a boundary lubrication path, and the frictional force is less than that of solid friction, but is greater than that of fluid lubrication. Therefore, it is common that the amount of wear is also large. Fluid lubrication is a condition where the oil film between the two sides is thick and, in an ideal case, the two sides do not come into direct contact. The friction is very small and wear is low. In general, lubrication does not have to be between metals, nor does it have to be oil that intervenes between the two surfaces. Sometimes it is a gas such as air or gas, and sometimes it is a solid such as graphite. In the present invention, lubrication has the same effects and properties as various engines and vehicles, as well as mechanical equipment parts, consumables, and tool life improvement effects. Second, the necessary conditions for the development of (water) cutting oil are as follows. The second is the cooling performance of (water) cutting oil. It is an important role in preventing fire and indoor pollution by reducing the mist (fume) of the product by cooling the frictional heat generated by the lubrication action, material temperature, and machine equipment temperature.

As a conventional patent technology, registered patent publication No. 10-1515983 includes lubricating base oil; Emulsifiers; water; In the water-soluble cutting oil composition comprising; and an additive,

The lubricating base oil reacts with hydrogen peroxide with one or more carbon-carbon double bonds and a carboxyl group at the terminal to epoxidize some or all of the carbon-carbon double bonds of the natural unsaturated fatty acid to produce epoxidation-fatty acids. And, the step of producing a hydroxylated-fatty acid in which two or more hydroxy groups are substituted by successively performing a ring-opening reaction of the epoxidation-fatty acid (step 1); And a condensation reaction of the hydroxylated fatty acids obtained in step 1 with each other, or a natural unsaturated fatty acid as a starting material of step 1 and the hydroxylated fatty acid obtained in step 1 condensation reaction with each other to prepare a condensed-fatty acid. A water-soluble cutting oil composition is disclosed, characterized in that it is prepared, including the step (step 2).

In addition, a water-soluble cutting oil is disclosed in Registered Patent Publication No. 10-1794618.

However, in the use of (water) cutting oil, the following problems have occurred frequently from the past to the present.

(Water) Depending on the use of cutting oil, corrosion of equipment or rust of material parts may occur due to aqueous solution. After cutting, the hardness of (water) cutting fluid by the fine (residual) chip increases, accelerating the decay rate of the product. (Water) Bubbles such as shampoo and foam occur from the surfactant contained in the cutting oil.

Third, the necessary condition for the development of (water) cutting oil is the stability of the undiluted solution. In addition, it can be seen as emulsion stability. As for the stability of the undiluted solution, the product is stable even in the four seasons, and the degree of separation and precipitation should not occur. The water-soluble cutting oil has good cost-effectiveness compared to the cost of using the product by diluting it to around 5-10% in water immediately before use. As a lubricant (cutting oil), as long as the emulsion stability (that is, an aqueous solution that is stable when diluted with water) is maintained, scum phenomenon should not occur. This can be seen as meeting the following three requirements for water-soluble coolant.

The composition of the conventional cutting oil is water (Water), dihydrogen oxide (DIHYDROGEN OXIDE); 5~10%, 1H-benzotriazole, (1H-BENZOTRIAZOLE) 0.2~0.8%, 1-Amino-2-Propanol or 2-Aminoethanol 3~8%, Tall Oil Fatty Acid 5~8%, trimethylolpropane Trioleic acid 2~3%, hydrotreated light paraffin refined oil (petroleum), Mineral Base Oil 40~60%, 1,2-BENZISOTHIAZOL-3(2H)-ONE 1~3%, alpha-dodecyl-omega -By using 2~4% of hydroxy-polyoxyethylene, 3% of 2-ETHYHEXANOIC ACID, and 3~5% of antiseptic and disinfectant, the purpose is to reduce raw materials by solubilization by 5~10%, minimize frictional heat of tool equipment, and wear materials. (Tool) Tip Long oil (fatty acid) and palm oil (trioleic acid) have been used in principle to extend the tool life and increase the surface roughness of the product by the lubricating protective film. However, in conventional cutting oil, tall oil (fatty acid) and palm oil (trioleic acid) become decay (acid) in the air. As a result, there is a problem of using harmful substances such as antiseptic disinfectants (CIT, BIT, CMIT) to maintain a pleasant working environment.

Therefore, the present invention has been devised to solve the above problems, and invents an eco-friendly water-soluble cutting oil by replacing the existing additive material with a new additive material and using the polyalkylene glycol fatty acid ester as a substitute for the existing fatty acid. It is intended to provide an eco-friendly water-soluble cutting oil composition and a method of manufacturing the same that replaces the preservative and disinfectant of the existing cutting oil.

In other words, it is intended to provide an eco-friendly water-soluble cutting oil composition and a method of manufacturing the same, which replaces the harmful (preservative) constituent substances of conventional (existing) cutting oil with chemically environmentally friendly substances and replaces fatty acids, a substance causing spoilage.

The development method of eco-friendly water-soluble cutting oil is defined as the HLB value balance 1~19 standard as follows. The HLB value (Hydrophilic-Lipophilic Balance) is a value indicating the degree of affinity of a surfactant to water and oil (a water-insoluble organic compound). When the HLB value is about 1-3, it hardly disperses in water and is used as an antifoaming agent. When the HLB value is about 3-6, it is partially dispersed in water, and is used as an emulsifier for W/O type emulsion. The HLB value is about 6-8. When mixing well, it becomes an emulsion by dispersing in water, and is used as an emulsifier and wetting agent for W/O type emulsions. When the HLB value is about 8-10, it disperses in the stability of water and becomes an emulsion, a wetting agent or O/W. It is used as an emulsifier for type emulsion. When the HLB value is about 10 to 13, it is translucent in water, and it is used as an emulsifier for O/W type emulsion. When the HLB value is about 13 to 16, it is transparently dissolved in water, and O/W It is used as an emulsifier and detergent for type emulsion. When the HLB value is about 16-19, it is transparently dissolved in water and used as a solubilizing agent. By adjusting the HLB value hydrophilic/lipophilic value, a W/O type basic lubricant, Parrffin Basic OIL, is added.

The formulation (synthesis) method for manufacturing the core development eco-friendly water-soluble cutting oil of the present invention is as follows.

The core additives as shown in Table 1 above are defined as follows in the order of combination. Distilled (pure water) is one substance that determines the concentration of the product with respect to the total content, up to about 5 to 10 parts by weight, and is determined by the amount by weight according to the chemical change according to the use and application of the product.

Butanolamine is mixed with distilled (pure water) and used as a pH adjuster in metal processing agents (water-soluble cutting oil) in the process of making alkali (aqueous solution). It is determined in parts by weight.

The mixed amine compound of butanolamine and propanolamine is mixed in a ratio of 1 to 67 parts by weight of butanolamine and 1 to 14 parts by weight of propanolamine with respect to 16 parts by weight of distilled water.

Butanol and propanol may be used alone, mixed with distilled water, if necessary.

Octanolamine is also used as a pH adjuster in metal processing agents (water-soluble cutting oils), and is determined in a ratio of 3.0 parts by weight according to the fatty acid content, i.e. (acid, alkali) composition ratio. At this time, the OH group of the amine structure is distilled (pure water). In the process of mixing with ), the reaction time is set to 5 minutes. The mixed amine compound of butanolamine and propanolamine and octanolamine are stirred and mixed together for 5 minutes. The overall role of amines has been used for a long time to prevent the phenomenon that the chip ions formed by on-site processing equipment parts only for finished products (diluents) are significantly biased to (acid) corruption, and the structural formula of the existing amine is shown in FIG.

Prior to the present invention, as a result of the previous experimental review, the performance effects of butanolamine, propanolamine, and octanolamine having the following structures were significantly superior to those of ethanolamine and propanolamine used in the past. Replace the existing alkaline amine. The structure of one mixed amine compound is shown in FIG. 2.

The performance result table of pH holding power that can determine the perishability in the field by using the same parts by weight as shown in Table 1 with respect to the contents of the mixed amine compound replacing the alkaline amine is as follows.

Tricarboxylic acid is set at a minimum value of 0.2 to a maximum value of 0.8 parts by weight, and if excessively added according to the blending center (balance) according to the composition ratio of the product, scum phenomenon and HLB value above the appropriate level are formed throughout the product emulsion, causing the starting point of the product to be unstable. The main performance of tricarboxylic acid is that it has anti-rust effect to protect rust generated by aqueous solutions such as metals (iron, stainless steel, forged steel, alloy steel, Sus), and if it is added below the minimum value, the site of use Rust may occur on parts, equipment and materials. In addition, tricarboxylic acid is a solid (powder) not a liquid, and this solid compound powder acts as a rust inhibitor, thixotropic agent, thickener, and lubricant by the action of tricarboxylic acid prepared by dimerizing unsaturated fatty acids obtained from clay catalysts. Therefore, in order to dissolve the solid powder of tricarboxylic acid in an alkali (aqueous) solution, the temperature is set at 50°C and the stirring time is set at 10 minutes. That is, a mixed amine compound of butanolamine, propanolamine, and octanolamine are mixed and stirred for 5 minutes, and then a solid powder of tricarboxylic acid is added, followed by stirring for 10 minutes. At this time, it is heated and maintained at 50°C. If the temperature drops below a certain level or if the stirring time is not observed, the solubility decreases and the possibility of precipitation (powder powder) in the cutting oil (used liquid) in the future is very high. Therefore, the composition table of Table 1 should be observed.

The hexanoic fatty acid introduced afterwards is an additive that has the same rust-preventing effect, and the substance has a liquid form, unlike tricarboxylic acid (solid). Hexanoic fatty acid with such a property has a composition ratio according to the acid-to-alkali ratio. Therefore, as shown in Table 1 above, the mixing ratio according to the alkali composition ratio is set to 3 parts by weight. If this material is also excessively added, a problem of decay may occur if the center of the product is biased toward excessive acid. After all of the tricarboxylic acid (solid) has been dissolved, hexanoic fatty acid is added and a stirring time is set for about 5 minutes to observe the chemical and physical changes.

Subsequently, about 3 to 5 parts by weight of the oleipam oil fatty acid to be added is appropriately administered according to the HLB balance, and after the addition, the first saponification reaction is initiated by a chemical reaction between an acid and an alkali. It is referred to as saponification reaction and (surfactant) reaction. The role of oleic palm oil fatty acids is to determine the HLB balance of cutting oil in the manufacturing process, and in applications where crude oil is vegetable fat oil, it withstands the weight (load) of the load and protects abrasion. Therefore, if it is added above the maximum value, the product's diluent form microparticles become shallow, which leads to insufficient lubricity and the pH value decreases, so decay (acid) may proceed quickly. Can be made.

Therefore, to perform the first saponification reaction of acid and alkali, the temperature is set at 60°C, and the stirring time is set at about 10 minutes. If the temperature falls below a certain level or the stirring time is insufficient, the chemical reaction is insufficient and the physical change is observed. There may be a problem that cannot be done.

Synthetic ester materials of polyalkylene glycol alkyl ethers are different from existing materials and have unique materials and advantages that are different from ordinary fatty acids. Foreign materials are used as a substitute for vegetable oils (fatty acids) that are currently decaying and are added in a composition ratio of about 2 to 5 parts by weight. It shows a very large tentative in antiseptic effect performance. Foreign substances can be mixed with existing vegetable oil (fatty acid) and used, and the stirring time after addition (the time at which chemical reaction occurs) is about 10 minutes, which is the same as that of existing vegetable oil (fatty acid). . Antiseptic effect substitutes for antiseptic disinfectants 2. The main frictional performance (lubrication) comparison of polyalkylene glycol fatty acid synthetic ester substances, which is a core substance replacing existing fatty acids, is as follows.

By making the PAG polyalkylene glycol fatty acid ester the same as in Table 1 and changing the parts by weight of various fatty acids, the evaluation index of the frictional performance (lubricity) is shown in Table 4 below.

Hydrotreated light paraffin refined oil (petroleum) is a lubricant (usually oil). In water-soluble cutting oils, petroleum oil is used as a large amount of basic base oil. As described above, 40 to 50 parts by weight of petroleum minerals are all metals. And in the non-ferrous metal cutting processing, it plays a role of forming a smooth surface by reducing frictional resistance by forming a thin oil film, and the viscosity of the oil has a property of about (7.5 to 8.5 Cst at Viscosity40°C). ) Has the advantage of maximizing lubrication by forming thick fine particles of cutting oil (diluent) in the development process, and plays a big role in boundary lubrication and fluid lubrication that require frictional force. It is used for smoothing the flow fluid) and is a petroleum-based (oil) refined oil without hydrophilic group (OH). It is cooled at 50°C with the upper material in Table 1, and stirring (reaction) is continued for about 20 minutes. If the stirring (reaction) time is insufficient or the temperature falls below a certain level, the compound may be separated, so care should be taken.

Antiseptic preservative butylene glycol is a viscous liquid with no odor and has a sweet taste. It is a type of polyol that has two hydroxyl groups (-OH), which are hydrophilic groups, and is obtained from fermentation products such as wine, soil yeast, corn oil, and sunflower seed oil. As an ingredient that can be used as a humectant, it has its own antimicrobial effect, so it can be used as an antiseptic aid, and it is a safe material that is harmless to the human body. In order for butylene glycol to exert antimicrobial effect, it needs about 10 parts by weight in O/W. Antiseptic preservatives should be cooled to below 40°C and added, and if the temperature is above a certain level, the appearance becomes dark and the spoilage preservation performance decreases. There is a risk of becoming.

Phenoxyethanol, an antiseptic preservative, is a phenol ether that combines phenol and ethylene glycol. Phenoxyethanol is one of the natural ingredients contained in green tea, and it is also chemically synthesized and used, and is one of the indirect food additives approved by the FDA in the United States. Pungoxyethanol molecule is composed of 10 hydrogen atoms, 8 carbon atoms, and 2 oxygen atoms, and is formed of a total of 20 atoms. Phenoxyethanol is harmless to the human body without causing carcinogenicity or toxicity, and phenol and ethylene glycol are synthesized. As an ingredient called phenol ether, it is partially used as an antiseptic preservative that has replaced toxic parabens in the cosmetics or wet tissue industry. Therefore, in order to replace with the existing antiseptic and disinfectant material, it should be added at 40°C or less, and the stirring (reaction) time to observe chemical reactions and physical changes is set at 5 minutes.

The antiseptic preservative is the following ASTM E 2275 test method using 1,3-Butanediol (Cas 107-88-0), Ethanol-2-Phenoxy (Cas 122-99-6), a reference safety substance registered with the U.S. ICID Food and Drug Administration. As shown in Table 1, the weight wt% was corrected to the composition weight part ratio according to the blending ratio, and the substitute materials used in Examples 1 and 2 were verified as the final decay performance test result in Example 3 below. .

11. Alkyloxy polyethylene oxyethanol is a surfactant that is not ionized and soluble in water, and is a polymer active agent synthesized by block polymerization or graft polymerization of a hydrophobic unit such as polyoxyethylene alkyl ether and a hydrophilic unit. It is used in various fields such as dispersants. It is also called nonionic active agent or nonionic surface active agent. Nonionic surfactant is added in a composition ratio of 2 to 4 parts by weight of the total weight, and if excessively added, a bubble phenomenon (foaming phenomenon) occurs, resulting in poor production efficiency during on-site parts processing. Disadvantages arise. In addition, if it is added below the standard value of 2 parts by weight, it is highly likely to become a semi-aqueous solution due to insufficient cleaning properties and poor hydrophilic groups and affinity of the aqueous solution (solution). Alkyloxy polyethylene oxyethanol works at 35°C or less and physical The final stirring time to observe the change is set to 10 minutes.

In the raw material input of the present invention, tricarboxylic acid is introduced in a solid state through an inlet formed at the top of the mixing and stirring tank, and the remaining raw materials are introduced in a liquid state through an additive tank. In the drawing, a stirrer that is rotated and stirred by an upper motor is installed inside the tank.
