Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to an emulsion for processing aluminum cans by drawing and ironing. [Prior Art] Beverage cans made of steel or aluminum, with a capacity of about 100ml to 300ml, are widely used for beverages such as youth and cola, and there are a wide variety of manufacturing methods. Currently, the most popular method for making cans is to draw a thin plate using a specified punch and die to form a cup shape, and then use ironing to stretch the side wall of the cup to form a cylindrical shape.Then, a lid is attached to the top. This is one of the methods. In this manufacturing method, a thin plate is drawn (referred to as drawing) and then ironed (referred to as ironing).Generally speaking, cans manufactured by this method are manufactured using both methods. It is called a can. After manufacturing, DI cans go through processes such as cleaning and printing.
After filling, the thickness of the thin plate for manufacturing DI cans is usually about 0.4 mm when commercially available aluminum is used as the material. (Hereinafter, the method of forming by drawing or ironing will be referred to as DI processing method,
Also, cans manufactured using this DI processing method are referred to as DI cans.) The DI processing method is a method similar to press processing in which a predetermined pressure is applied to the base material (thin plate) to cause plastic deformation. , from its usage, product accuracy, appearance, DI
Strict performance is required, including can surface characteristics. For this purpose, the material is simply punched and diced during processing.
It is impossible to perform DI machining, and normally the processing part is processed by reducing the coefficient of friction between the workpiece and the punch or die, reducing the machining pressure, and cleaning and smoothing the surface to ensure smooth machining. Processed oil is used for this purpose. Furthermore, this processing oil is supplied in the form of a processing oil emulsion using water as a coolant in order to remove the processing heat associated with plastic deformation and improve product precision. In the DI processing method, a processing oil emulsion is continuously supplied by a pump, etc. to both the drawing process, which transforms the material into a cup shape while maintaining its thickness, and the ironing process, which stretches the side walls of the cup. . Here, the processing oil used at this time is:
It is common to use an emulsion type in which the lubricating oil component of the processing oil is emulsified with a surfactant. This type of processing oil is mainly composed of hydrocarbons (mineral oil), with the addition of fatty acids or their salts (such as alkanolamines) and fatty acid esters, which act as oiliness improvers in lubrication. In addition, a nonionic surfactant or an anionic surfactant such as a sulfonic acid or carboxylic acid salt is added to the product, which increases the Those that allow the formation of processed oil emulsions in water are generally used. Further, the concentration of processing oil in the emulsion varies depending on the processing conditions, but is relatively high, approximately 10 to 30%. On the other hand, the characteristics required for DI cans include no surface defects, high processing accuracy, and processing operation stability. It can be said that the influencing factor of oil is a major factor. Here, the surface defect refers to flaws or partial discoloration on the can surface, or glossiness of the entire can surface. Surface flaws are caused by seizure phenomena caused by metal-to-metal contact from the breakage of the lubricating oil film that exists between the can surface and the die during processing, or by scratching of the can surface by solid objects such as generated metal powder. This refers to the occurrence of countless linear scratches on the can surface, and partial discoloration is thought to be related to the composition of the processing oil, its lubrication performance, DI processing conditions, water, processing heat, etc. Usually referred to as "black streaks," this term refers to fine brown to black streak-like discoloration that occurs on the surface of cans. Furthermore, the glossiness of the can surface is considered to be related to surface irregularities, that is, surface degree and surface dirtiness. These defects are largely due to the processing oil mentioned above, but can also be caused by performance deterioration due to deterioration of these processing oils, can breakage of DI cans (in the can circumferential direction or can stretching direction), and deterioration of lubricity. The use of machining oil is prohibited in the DI machining method, regardless of the contamination of the DI can surface due to a decrease in can dimensional accuracy (generation of machining heat), a large amount of metal powder generated during machining, or a large amount of metal powder adhering to the emulsion. It was essential. [Problems to be Solved by the Invention] As already mentioned, emulsified type processing oil using a surfactant has been used in the production of this DI molded can. This type of processing oil uses water and is used as an emulsion during DI processing, but in order to ensure emulsion stability from the beginning, it is currently formulated with a large amount of emulsifier, etc. . The method of supplying processing oil in normal DI processing is as follows:
The emulsified processing oil (hereinafter referred to as coolant) passes through a strainer to remove dust and relatively large metal powder, and is injected into the DI forming can processing section by a supply pump, and from the processing section and In most cases, a circulation system is adopted in which the emulsion is returned to the emulsion storage tank. In this supply system, when emulsified type processing oil is used, it has the following drawbacks and has problems such as stable operation. In other words, since it is an emulsion using an emulsifier,
The contamination of the emulsion with metal powder, etc. generated during operation can cause the emulsion to become unstable, leading to unstable operations, a decrease in the surface quality of the DI molding can, and even deterioration of the environment due to contamination of equipment, etc. Ta. To explain these problems in more detail, the emulsifier used for emulsification should have an optimal HLB so as to be stable.
In other words, stability is maintained by the HLB of the emulsifier, but depending on the stability and operability of the emulsifier in the oil particles in the emulsion, changes in the balance of the emulsifier caused by disturbances may cause the processing oil emulsion to change. The characteristics changed significantly over time, causing problems in operations. This is because different oils such as processed metal powder and bearing oil are mixed into the emulsion during operation, which changes the required HLB of the emulsifier and causes the emulsion to become unstable. ,
Because the surface protection of oil particles by the emulsifier in the emulsion is relatively weak (this is due to the fact that the oil particle size distribution in the emulsion due to the emulsifier ranges from small ones to large ones produced by the coalescence of these particles). (This indicates that the surface protection properties of the oil particles are weak. It occurs as the condition progresses. From the above, it can be seen that disturbances caused by operations lead to destabilization and contamination of the emulsion, but DI
The effects on the processing of molded cans include uneven processing oil due to emulsion instability (unstable processability), changes in can surface properties due to contamination of processing oil [tightness of the molded can surface due to adhesion of metal powder] A large number of scratches, damage to dies, etc., contamination of the can surface due to adhesion of contaminated processing oil mixed with foreign oils (affecting gloss, etc.), and environmental pollution due to adhesion of contaminated processing oil around the processing and molding machine, etc. ], and many problems occurred over time. To describe these more specifically, in actual operations, when manufacturing DI cans, emulsified processed oil emulsion is placed in an emulsion circulation tank (10 to 30%
(Generally, the concentration is within the range of 100 to 100%), but in this case, a stable emulsion is formed using the emulsifier as described above. However, the oil particles in the emulsion at this time range from extremely small particles of 1 to 2 μm.
Its distribution is wide-ranging, even down to coarse particles of several tens of micrometers. This emulsion is supplied to the DI can forming section via a supply pump and a strainer (filter).
DI cans are then manufactured continuously using a circulation method that returns the DI cans to a circulation tank. Due to emulsion circulation, a large amount of metal powder generated during processing and bearing oil used in processing machines get mixed into the emulsion over time, but these make the emulsion unstable and cause the circulation tank to The floating of oil containing a large amount of metal powder on the surface of the emulsion (black appearance) and the clogging of the filter of the emulsion containing a large amount of metal powder are occurring frequently, so it is necessary to clean the emulsion. Since it required work such as draining floating oil and replacing filters, there were many problems in terms of operational stability. In addition, the "deterioration" of these emulsions has a great effect on DI molded cans.
In terms of quality, lubrication instability due to uneven adhesion of processing oil during processing due to emulsion instability, scratch-like flaws on the surface of DI molded cans due to entrapment of metal powder in processing oil, or Surface damage such as seizure flaws (both flaws occur in large numbers in a linear pattern) caused by contact between the die and the surface of the molded can due to unstable lubrication;
Due to the adhesion of processing oil, surface contamination such as a large amount of metal powder adhering to the can surface and a decrease in surface gloss due to lubrication instability occur, and this change in emulsion has a significant impact on quality. I can say it. As described above, with the type of processing oil that uses emulsifiers, destabilization of the emulsion is a real problem, and conventionally, it has been necessary to stabilize operations and improve the processing oil consumption rate by renewing the processing fluid due to emulsion contamination. Although efforts have been made to improve the above, the current situation is that a satisfactory processing oil has not yet been found. For this reason, there has been a strong desire to develop a so-called "clean" processing oil for DI molded cans, which has stable emulsions over time and is free from contamination. [Means for Solving the Problems] Therefore, the present inventors conducted intensive research to solve the above problems, and found that if a specific water-soluble polymer compound is used without using an emulsifier, metal powder and mechanical The present invention has been completed based on the discovery that an emulsion for drawing and ironing forming aluminum cans can be obtained which is stable even when mixed with oil and the like and has no trouble during operation.

〔Effect of the invention〕

A new aperture using water-soluble polymer compounds
It is thought that the emulsion for processing aluminum cans can be manufactured easily by stabilizing the processed oil emulsion, and its quality can also be improved. In other words, metal powder that gets mixed into the emulsion over time settles as particles at the bottom of the circulation tank, and is also captured as metal powder in the strainer (filter), resulting in filter clogging and oil trapping. Emulsion overefficiency or processing oil consumption is reduced due to almost no acceleration, and work efficiency is significantly improved. Moreover, since it does not have the ability to mix different types of oil into the emulsion, it is possible to have it exist as an oil layer in the upper part of the circulation tank. From the above, it can be used as a constantly clean emulsion that removes metal powder or foreign oil from the system, and excellent lubricity is maintained due to the large particle size of the processing oil and its uniform adhesion. By using processing oil at a low concentration, making emulsion management easier, etc., it is possible to reduce the unit consumption of processing oil. Currently, the emulsified type DI processing oil used is
It is difficult to obtain such characteristics. Further, excellent effects obtained by applying the processing oil composition of the present invention include improved wastewater treatment properties (low COD load) of the emulsion after use and improvement of the working environment. These are based on the action of the applied water-soluble polymer compound, but the wastewater treatment properties vary from the general treatment method for emulsions after use, from standing (oil separation) to adjusting the pH of the lower layer (acidification). In the process leading to neutralization, the polymer compound acts as a flocculating agent when adjusting the pH, so when the processability is expressed as a COD value, it is significantly lower than that of conventional processing oils, making it an excellent product. It exhibits excellent wastewater treatment properties. In the conventional emulsified type, the oil particle size distribution is wide-ranging, but the extremely small stabilized particles cannot be completely removed by the above-mentioned treatment method, causing problems in wastewater treatment. It was hot. In addition, in terms of the working environment, in the conventional type, contaminated machining oil tends to adhere unstably around the machining part and accumulate dirt, polluting the environment, but with the machining oil of the present invention, The continuous supply of clean emulsion prevents the progress of contamination, and the hydrophilic effect of the polymer compound cleans already contaminated areas, making it useful in the working environment. It can be said that it is a composition. [Example] Examples will be described below.
