Description

[Detailed description of the invention]

The present invention relates to a novel cleaning agent composition for processing machinery containing a specific water-soluble polymer compound. For example, in processing machines that use lubricating oil or bearing oil, such as metal hot or cold rolling machines, press machines, cutting/polishing machines, steel pipe manufacturing machines, etc., the heat generated during metal processing, the pressure applied, etc. Many factors such as lubricating oil temperature, involvement of water supplied to the processing section as a lubricating oil emulsion, and generation of active metal powder during processing are involved, and lubricating oil components (e.g. beef tallow, palm oil, etc.) Fats and oils, mineral oils, synthetic esters, fatty acids) change due to chemical reactions, self-decomposition, etc.
It is well known that so-called scum, which is a mixture of metal powder, reaction products of metal powder and lubricating oil components, or decomposition products of lubricating oil components, is generated. However, it is extremely difficult to prevent the occurrence of scum in processing machines, and due to the accumulation of scum over time, the scum adheres to the workpiece and causes contamination of the workpiece, and the lubricating oil or lubricating oil emulsion is contaminated with scum. Changes in lubricity due to scum contamination, resulting in unstable work and deterioration of the environment.
This causes various problems such as the occurrence of fire. Therefore, in order to eliminate these problems, the current practice is to periodically remove the scum that has adhered to the machine using a cleaning agent. Conventionally, this cleaning has been carried out by spraying an alkaline type, a neutral type mainly composed of a surfactant, or a petroleum solvent type cleaner mixed with water. However, these detergents each have their own advantages and disadvantages, and are not satisfactory. In other words, emulsion or soluble types of petroleum solvents such as kerosene and solvent naphtha have excellent ability to dissolve the oil in the scum, but they pose risks such as ignition and harm to the human body due to inhalation of mist. There is a big drawback to this. In addition, the neutral type contains oil in the scum,
Because it emulsifies or disperses metal powder, there is little risk of flammability, but it has low cleaning power and contains a large amount of surfactant, which causes major problems in wastewater treatment after cleaning. Furthermore, although alkaline types have stronger cleaning power than neutral types, they have lower cleaning power than petroleum-based solvent types and contain alkaline agents that may come into contact with the worker's body (eyes, skin). This has the disadvantage of being dangerous. Under these circumstances, the present inventor has conducted various studies in order to provide a cleaning agent for processing machines that does not have the above-mentioned drawbacks and has excellent scum removal properties. Therefore, they discovered a cleaner composition that is safe for the human body and removes scum by a mechanism different from conventional cleaners, and completed the present invention. That is, the present invention provides a cationic or zwitterionic polycondensate or a salt thereof having a basic or cationic nitrogen atom in a molecule with a molecular weight of 10 to 10 million; Anionic polycondensates having an amide group or salts thereof, olefin-maleic acid copolymer salts, acrylic acid or methacrylic acid-maleic acid copolymer salts, homopolymer salts of acrylic acid or methacrylic acid, or these The present invention provides a cleaning agent composition for processing machinery containing one or more water-soluble polymer compounds selected from the group consisting of copolymer salts and polymers of acrylamide alkylene sulfonic acid.

The processing machine cleaning agent composition of the present invention is preferably used in the form of an aqueous solution by dissolving one or more of the water-soluble polymer compounds described above in water. If necessary, 0.01 to 10% by weight (hereinafter simply referred to as %) of a known water-soluble rust preventive/corrosive agent may be added.

The concentration of the water-soluble polymer compound when using the processing machine cleaning composition of the present invention is 100 to 100,000 ppm,
Particularly preferred is 300 to 50,000 ppm. Cleaning of scum and the like is carried out by spraying this composition onto the area to be cleaned or by immersing the object to be cleaned in the composition. Although the details of the cleaning effect on scum and the like by the preparation composition of the present invention are not clear, it is presumed to be as follows. In other words, since the surface tension of the aqueous solution of the water-soluble polymer compound used in the present invention is almost the same as that of water, it does not have the effect of emulsifying or dispersing dirt like a surfactant, but it quickly adsorbs to the dirt surface. The dirt surface is covered with a three-dimensional or protective colloid characteristic of polymer compounds, making the dirt hydrophilic, reducing the adhesion caused by agglomeration and coalescence of dirt, and giving fluidity. It is believed that the dirt can be easily removed by force, such as spray pressure. Therefore, the cleaning agent for processing machines of the present invention has the following features. Dirt can be easily cleaned and removed with a little physical force. Since the surface of dirt such as scum is covered with the polymer compound, the removed dirt is not sticky and can be easily disposed of. After treatment, dirt does not emulsify or disperse in water, so
It can be separated more easily than water, and wastewater treatment is therefore easier. Since there is less dirt mixed into the water, the cleaning power lasts for a long time. Since water-soluble polymer compounds act as flocculants, they have a large wastewater treatment capacity. Since it is neutral, it is safe for the human body. There is no risk of fire etc. Since the cleaning agent composition of the present invention has the above-mentioned excellent characteristics, it can clean dirt (scum) generated by using lubricants during metal machining, and can also clean dirt (scum) that is generated by using lubricants during metal machining. The resulting dirt,
For example, it can be used to remove crude oil sludge adhering to the walls of crude oil tanks in tankers, and to clean tar pit sludge in oil refinery facilities.
