Abstract
The present invention provides a water-soluble metal working oil composition with unit dosage, which can be put into practical use in the field of industrial medicines, particularly metal working. A water-soluble metal working oil composition of unit dose is prepared by sealing a water-soluble metal working oil composition and/or a water-soluble metal working oil component in a water-soluble packaging container made of a water-soluble film material.
Description
Technical Field
The present invention relates to a unit dose of a water-soluble metalworking fluid composition used in a metalworking process, which is used for simple and safe chemical injection when a stock solution of the water-soluble metalworking fluid composition is injected into a water storage tank to prepare a diluent, and when the stock solution is injected into a water-soluble metalworking fluid used solution to supply the water-soluble metalworking fluid composition or adjust the concentration of components, and a method for producing the diluent.
Background
In the metal working step, a water-soluble metal working oil is generally used. The metal working oil is used by adding a predetermined amount of the stock solution to a tank or a tank to prepare a diluted solution diluted with water, instead of using the stock solution as it is. In addition, in order to prevent various problems caused by changes in the balance of components and deterioration of components with time, the concentration of the use solution is controlled by periodically supplying the stock solution and additives.
In the dilution work and the replenishment work, the worker not only takes time and effort to weigh the oil agent stock solution, the additive, and the like each time, but also has a risk of hand roughness due to direct contact with the oil agent stock solution, the additive, and the like, or has a problem of odor emission from the oil agent stock solution even if the worker does not come into contact with the oil agent stock solution, the additive, and the like.
As a countermeasure for solving these problems, industrial drug manufacturers have studied formulations with less skin irritation, which hardly cause hand roughness, and have made countermeasures such as selecting raw materials with mild odor.
In a metal working factory where a metal working oil is used, for example, measures such as introduction of an automatic dilution device are taken. The use of the automatic dilution device has advantages such as allowing an operator to weigh the oil solution stock solution without taking the trouble of weighing the stock solution each time, avoiding the risk of direct contact, and the like, and has a problem in that the automatic dilution device is expensive to introduce, and even when introduced, the automatic dilution device has a structure for pumping out the stock solution, and therefore, there is a limitation that the automatic dilution device cannot be applied to a case where the stock solution has a high viscosity.
On the other hand, in the field of household washing, from the viewpoints of saving such a measure, avoiding contact with a chemical substance, and omitting disposal of a packaging material, etc., it has been proposed to use a unit dose article (unit package) in which a detergent is added to a packaging container containing a water-soluble resin film such as polyvinyl alcohol (PVA) (see, for example, patent documents 1 and 2).
However, the method using the unit dose has not been put to practical use in the field of industrial chemicals. The main reasons for this include the following: (1) in the diluting operation, the chemical agent is fed to fresh water as in the case of washing, but in the replenishing operation, the chemical agent is not fresh water but water containing chemical components of the metal working oil; (2) the industrial tank has an overwhelmingly large capacity as compared with the case of the household washing machine, and the stirring force of the tank is not as strong as that of the washing machine; (3) in the case of household washing, there is no great difference in the washing capacity of the washing machine used in each household, and a detergent manufacturer needs only to supply a certain amount of a unit dose, but in the field of industrial chemicals, the capacities of tanks and tanks installed in each metal processing factory are various.

Detailed Description
One of the main reasons for the difference between the industrial chemical field, particularly the metal working field, and the household detergent field is that the oil agent is introduced not only into fresh water but also into water containing chemical components of the oil agent, and the water containing chemical components of the oil agent is required to be easily soluble, and further, since agitation such as in a washing machine is not performed, it takes time to dissolve the water-soluble film, and the amount of industrial products is large, and if the film thickness of the water-soluble film is increased by maintaining sufficient strength, it takes more time to dissolve the water-soluble film.
The water-soluble metal working oil composition of the present invention dissolves rapidly in fresh water and in water containing chemical components of the oil, is resistant to impacts during transportation, and has sufficient strength even when stored for a long period of time. In the present specification, a substance in which a water-soluble metalworking fluid composition is sealed in a water-soluble packaging container and a substance in which a component used to form the water-soluble metalworking fluid composition (referred to as a water-soluble metalworking fluid-forming component in the present specification) is sealed in a water-soluble packaging container are collectively referred to as a water-soluble unit dose metalworking fluid composition.
The water-soluble metal working oil composition contains a base oil as a main component, an oiliness agent, a surfactant, and a component selected from a lubricity improver, a rust inhibitor, an antifoaming agent, an extreme pressure agent, a coupling agent, an anticorrosive agent, an antiseptic agent, a chelating agent, an oil separating agent, a coloring agent, a perfume, and the like as an additive, and is diluted with water for use. Examples of the base oil include mineral oils (spindle oil, diesel oil, kerosene, machine oil, etc.) and synthetic oils (polyolefins, diesters, hindered esters, etc.), and examples of the oily agent include vegetable oils such as rapeseed oil, soybean oil, castor oil, coconut oil, etc., and animal oils such as lard oil. Examples of the surfactant include anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants, and anionic surfactants, cationic surfactants, and nonionic surfactants are preferable. Examples of the rust inhibitor include organic carboxylic acids and organic amines, and these can be used in combination. Examples of the extreme pressure agent include sulfur-based, phosphorus-based, and organic metal compounds. Examples of the preservative include phenol-based preservatives, formaldehyde donors, and the like. Examples of the coupling agent include alcohols.
Typical types of water-soluble metalworking fluid compositions include emulsion type (a 1 types according to JIS classification), soluble type (a 2 types according to JIS classification), and solution type (A3 types according to JIS classification) emulsified in water. The dilution ratio of the water-soluble metal working oil composition varies depending on the application, and is usually about 5 to 100 times, preferably about 10 to 50 times.
The emulsion type is a substance diluted with water to form a milky emulsion, and in general, is a substance containing a base oil and/or an oily agent and a surfactant as an emulsifier. The soluble type is obtained by adding a surfactant to an emulsion type, and generally, a synthetic polymer is used as a base oil to form a translucent or transparent solution. The solution type includes those containing a water-soluble lubricant such as polyalkylene glycol as a main component.
Among these, the water-soluble metal working oil composition sealed in the water-soluble packaging container is preferably an emulsion-type oil composition from the viewpoint of being rapidly dissolved in a solution containing an oil agent.
The content of water in the water-soluble metalworking oil composition sealed in the water-soluble packaging container is preferably less than 10 mass% for maintaining the strength of the water-soluble packaging container. The pH of the stock solution of the water-soluble metal working oil composition sealed in the water-soluble packaging container is preferably 7.5 to 12, more preferably 7.5 to 10. In the case where the water-soluble metal working oil composition is alkaline to weakly alkaline, the water-soluble film material constituting the water-soluble packaging container preferably has alkali resistance.
The water-soluble film material used for the water-soluble packaging container is not particularly limited as long as it is water-soluble, and examples thereof include water-soluble film materials containing 1 or 2 or more kinds of resins selected from polyvinyl alcohol, hydroxyethyl cellulose, polyvinylpyrrolidone, starch, glycerin, gelatin, and the like. Among these, a water-soluble film material containing polyvinyl alcohol is preferably used because necessary mechanical strength and moisture resistance during processing can be controlled by changing various conditions such as the polymerization degree and saponification degree of polyvinyl alcohol and the blending ratio of additives such as starch.
Commercially available polyvinyl alcohol (PVA) products include, for example, M8630 and M8900 available from MonoSol corporation.
The water-soluble film material preferably has a film thickness of about 40 to 70 μm, more preferably about 45 to 64 μm. When the film thickness is about 40 to about 70 μm, the film has sufficient film strength and practical film solubility. Of the commercially available products, 2.0mil (51 μ M) of M8630 available from MonoSol corporation is most suitable.
The water-soluble packaging container may contain a component (water-soluble metal working oil component) used for forming the water-soluble metal working oil composition, that is, a main agent and/or an additive. Examples of the main agent include base oils, oiliness agents, and surfactants, and examples of the additive include lubricity improvers, rust inhibitors, antifoaming agents, extreme pressure agents, coupling agents, corrosion inhibitors, antibacterial agents, chelating agents, oil separating agents, colorants, and fragrances. The water-soluble metal working oil contained in the water-soluble packaging container may be a simple substance or a mixed substance. Examples of the mixed component include mixing of the main components, mixing of the additives, and mixing of the main components and the additives. The water-soluble metal working oil component may be diluted with water.
The content of water in the water-soluble metal working oil component enclosed in the water-soluble packaging container is preferably less than 10 mass% for maintaining the strength of the water-soluble packaging container. The pH of the water-soluble metal working oil component enclosed in the water-soluble packaging container is preferably 7.5 to 12, more preferably 7.5 to 10. When the water-soluble metal working oil composition is alkaline to weakly alkaline, the water-soluble film material constituting the water-soluble packaging container preferably has alkali resistance. Therefore, the water-soluble film material used for the water-soluble packaging container in which the constituent components of the water-soluble metal working oil agent are sealed preferably contains polyvinyl alcohol (PVA), and the film thickness of the water-soluble film material is preferably about 40 to 70 μm, and more preferably about 45 to 64 μm.
When a water-soluble metal working oil composition is put into a water storage tank to prepare a diluted solution and when a water-soluble metal working oil composition is put into a water-soluble metal working oil use solution to replenish the water-soluble metal working oil composition, if a unit dose of the water-soluble metal working oil composition, preferably an emulsion type oil composition, sealed in a water-soluble packaging container made of the above-mentioned water-soluble film material is used (hereinafter referred to as the product of the present invention), the water-soluble metal working oil composition exhibits easy solubility even with weak agitation.
The metal working oil composition having a water-soluble unit dose can preferably take any of the following forms (1) to (6).
Form (1): the water-soluble packaging container has a plurality of separable sections, and the sections have at least 1 section in which the water-soluble metalworking oil composition is enclosed and at least 1 section in which the water-soluble metalworking oil component is enclosed.
Form (2): the water-soluble packaging container has 1 or a plurality of separable compartments, and a water-soluble metalworking fluid composition is sealed in each of the compartments.
Form (3): the water-soluble packaging container has 1 or a plurality of separable sections, and the water-soluble metal working oil components are sealed in each of the sections.
Form (4): the water-soluble packaging container has a multilayer structure, and at least 1 layer in which the water-soluble metal working oil composition is enclosed and at least 1 layer in which the water-soluble metal working oil component is enclosed are arranged.
Form (5): the water-soluble packaging container has a multilayer structure, and a water-soluble metal working oil composition is sealed in each of the layers.
Form (6): the water-soluble packaging container has a multilayer structure, and water-soluble metal working oil components are sealed in each of the layers.
The amount of the water-soluble metal working oil to be sealed in each partition or each layer is not particularly limited, and may be preferably in the range of 100 to 1000g (or 100 to 1000ml), and for example, may be 100g (or 100ml), 500g (or 500ml), and/or 1000g (or 1000 ml). When the input amount of the oil agent into a water storage tank and the like reaches dozens of kilograms to hundreds of kilograms, the oil agent with the cylinder specification or the 1-bucket tank (Japanese original text: 1-bucket potter) specification is used, and the insufficient zero amount can be supplemented by the product. Therefore, a unit dose of the enclosed amount corresponding to several thousand grams or several hundred grams is required. If the unit dose of the enclosed amount is prepared, the ordinary preparation and replenishment work of the oil-diluted solution having different tank capacities is not hindered. The amount of the water-soluble metal working oil constituting component enclosed in each partition or each layer is not particularly limited, and may be preferably in the range of 100 to 1000g (or 100 to 1000ml), for example, 100g (or 100ml) and/or 500g (or 500ml) and/or 1000g (or 1000 ml).
As a possible form of the water-soluble unit dose metalworking fluid composition, for example, as shown in fig. 1, the water-soluble packaging container 2 used in the water-soluble unit dose metalworking fluid composition 1 of the present invention may be configured to have a perforated wire 3, have a plurality of enclosed portions, and be individually cut out by the perforated wire 3. The water-soluble unit dose metalworking fluid composition 1 shown in fig. 1 has a partition 4 in which the main amount (large volume) of the water-soluble metalworking fluid composition is enclosed, and a partition 5 in which the same water-soluble metalworking fluid composition of small volume for fine adjustment is enclosed. Examples of the water-soluble metalworking fluid composition include those obtained by adding a performance-enhancing additive such as a lubricity improver, a rust inhibitor, an antibacterial agent, an antifoaming agent, and an oil separating agent to a base compound.
As shown in fig. 2, each of the compartments 6, 7, 8, and 9 for enclosing the water-soluble metalworking oil composition partitioned by the porous wiring line 3 may have different internal volumes (for example, 500ml for the compartment 6, 300ml for the compartment 7, 200ml for the compartment 8, and 100ml for the compartment 9), and a desired input amount may be adjusted by a combination of the internal volumes.
Fig. 3 shows a water-soluble unit dose metalworking fluid composition 1 of the present invention having 2 independent compartments 10 and 11 which can be separated by a perforated wire, and a main agent and an additive are sealed in each of the 2 compartments.
Fig. 4 shows a water-soluble unit dose metalworking fluid composition 1 having a multilayer structure, 10 being an outer region and 11 being an inner region. For example, when the main agent is enclosed in the outer partition 10 and the additive is enclosed in the inner partition 11, the main agent is released first and then the additive is released. For example, by increasing the thickness of the film material in the inner portion and decreasing the thickness of the film material in the outer portion, a time difference can be provided between the dissolution of the main agent and the dissolution of the additive.
In the case of a package for storage and transportation of the water-soluble unit dose metalworking finish composition, a protective sheet may be disposed between the water-soluble unit dose metalworking finish compositions in a case having a top face, a bottom face, and 4 side faces, and stacked and stored so that the water-soluble unit dose metalworking finish compositions do not contact each other. For example, as shown in fig. 5, when the sheet-like water-soluble unit dose metalworking oil composition 1 of the present invention is stacked and stored in a case 12 and transported to form a bag, a protective sheet 13 for buffering is interposed between the water-soluble unit dose metalworking oil compositions 1, and the water-soluble unit dose metalworking oil compositions 1 are not in direct contact with each other, whereby breakage of the water-soluble unit dose metalworking oil compositions 1 can be prevented. The protective sheet 13 may be an aluminum sheet.
By using the present invention, a water-soluble metal working oil agent having a desired concentration can be prepared. For example, in the first use mode, a unit dose of the water-soluble unit dose metalworking fluid composition of the present invention set to a predetermined concentration and a predetermined enclosed amount is prepared, and the unit dose is put into a water storage tank or a water-soluble metalworking fluid use solution to produce a diluted solution of the water-soluble metalworking fluid composition of a desired concentration.
In the second use mode, a unit dose of the water-soluble unit dose metalworking fluid composition of the present invention set to a predetermined concentration and a predetermined enclosed amount is prepared, and the unit dose is put into a water-soluble metalworking fluid use solution to adjust the concentration of the water-soluble metalworking fluid. In the second use mode, the concentration of the entire water-soluble metal working oil agent can be adjusted, and the concentration of only a specific component can be adjusted. In the second usage form, the components contained in the water-soluble unit dose metalworking fluid composition may not be contained in the water-soluble metalworking fluid usage liquid. Therefore, by newly adding components that are not contained in the original water-soluble metal working fluid, the performance of the water-soluble metal working fluid can be enhanced or new performance can be imparted.
