Description

Cleaning agent composition, cleaning aerosol, and method for cleaning contaminated part
Technical Field
The present invention relates to a cleaning agent composition which is reduced in the erosion property to a plastic substrate such as polycarbonate and polystyrene and improved in the cleaning property to grease and oil. The present invention also relates to an aerosol for cleaning using the cleaning agent composition and a method for cleaning a contaminated part by removing contaminants using the aerosol for cleaning.
Background
Conventionally, cleaning agents for cleaning industrial parts have been used for cleaning grease adhering to surfaces of industrial machines, conveyors, electric and electronic equipment, building materials, and the like. In particular, in a conveyor such as a vehicle, a train, a tractor, a ship, an airplane, or a forklift, grease for lubrication, cooling, or the like adheres to various parts of a driving part and a sliding part, and these grease are scattered by driving, or contaminants present in the surrounding environment during driving adhere to the surface of the conveyor, thereby staining the surface of the conveyor. Heretofore, in order to remove such contamination, a cleaning agent containing petroleum hydrocarbon and alcohol has been used, and these solvents are dangerous substances in the fire control law because of their high flammability. If the cleaning agent belongs to a dangerous object, the installation and management of a dangerous object warehouse are required, and the cost is required in the aspects of introduction and maintenance, so that the cleaning agent is required to be used as a non-dangerous object. In order to clean such stains, a cleaning agent composition containing a fluorine-based solvent, which is not a hazardous substance, is also used. Further, although the member to be cleaned has been conventionally made of metal, there is a demand for a cleaning agent for a composite of a plastic part and a metal part as the members are diversified. However, a cleaning agent using a fluorine-based solvent, which has been conventionally used as a cleaning agent, has a problem of corroding a plastic substrate. In particular, polycarbonate and polystyrene have low solvent resistance and are therefore corroded by the use of conventional detergent compositions. Against such a background, a demand has arisen in recent years for the development of a cleaner composition which does not corrode a plastic substrate. (patent document 1)

A hole having a diameter of 6mm was bored in the center of a polycarbonate plate (L-1225Y, manufactured by Diko K.K.) having a width of 25mm, a length of 100mm and a thickness of 2mm or a polystyrene plate (HIPS, manufactured by DIC K.K.) by using an electric drill, and then a bolt of M6 was passed through the hole and fixed by a tightening torque of 6N using a nut to obtain a test piece. 90ml of each detergent composition was put into a glass bottle having a capacity of 100ml, and the test piece was immersed for 15 seconds in an atmosphere of 25 ℃ X55% RH. Then, the test piece was left to stand for 10 minutes to be dried in an atmosphere of 25 ℃ x 55% RH, and the state of the resin plate was confirmed by visual observation.

O: no dissolution or cracking occurred on the plastic plate.
X: the plastic plate is dissolved and cracked.

As shown in Table 1, the compositions of examples 1 to 9 containing the components (A) to (C) and the components (A) and (B) in a specific ratio have excellent detergency to turbine oils and fats without corroding plastic substrates such as polycarbonate and polystyrene. On the other hand, it is found that if the component (a) is small as in comparative example 1 of table 2 or if the component (C) is not contained as in comparative example 4, the cleaning property of the turbine oil or grease is deteriorated, and the polycarbonate or polystyrene is corroded in comparative example 2 in which the component (a') is used instead of the component (a) or in comparative example 3 in which the component (B) is not contained. Further, when the component (B') is used in place of the component (B), the cleaning property of the turbine oil or grease is also deteriorated. According to the above results, by mixing the components (A) to (C) at a specific ratio, both low-corrosiveness and cleanability to the plastic substrate can be achieved.
While the present invention has been described in detail with reference to the specific embodiments, it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the present invention. The present application is based on japanese patent application 2020-211352, filed on 12/21/2020 and the content of which is incorporated by reference.
Industrial applicability
The cleaning agent composition of the present invention is excellent in cleaning property and does not corrode a solvent-free plastic substrate such as polycarbonate and polystyrene, and therefore, can be used for a wide range of cleaning applications and is very useful.
