Problems solved by technology

[0006] However, the detergent compositions of (1) and (2) have good solubility for asphalt wax, but are not sufficiently soluble and removable for other asphalt and resin-based protective films.
In addition, the cleaning agent of (3) not only can only dissolve and remove asphalt and part of the resin-based protective film, but also has the problem of the influence of aromatic compounds on the environment and human body and strong odor.
In addition, the cleaning agent of (4) above exhibits generally good removal performance against fixatives such as asphalt wax and asphalt and all protective films, but it cannot be said to be sufficient, and it is difficult to make it effective against both asphalt and protective films. Has sufficient cleaning power

reference example 1

[0053] Kokonoe grinding bitumen grade K grade No. 8 (manufactured by Konoe Electric Co., Ltd.) was shaped into a button shape with a diameter of 6 mm, and a fixed sample was prepared. The weight of the fixed bitumen was measured and found to be 56.2 mg. Next, this sample was immersed in 20 ml of cleaning agent (Naphthene-based cleaning agent TPS-3200 manufactured by Tokuyama Corporation) maintained at 25° C. for 20 minutes. After that, the sample was taken out, dried, and the weight of the remaining pitch adhering to the glass plate was measured, and it was 17.1 mg. The difference in residual weight was subtracted from the initial weight to obtain the weight of the removed pitch, which was 39.1 mg.

[0054] In addition, visual observation of the cleaning solution during and after the sample immersion showed no peeling of pitch, and it was a uniform solution. It can be seen that the asphalt is all removed by dissolution.

Embodiment 1～3 and comparative example 1～6

[0060] For cleaning agents using the compositions shown in Table 2, various removal target substances [cleaning target substances: Kokonoe asphalt grade K grade No. 8 (manufactured by Konoe Electric Co., Ltd.) (hereinafter referred to as bitumen K-8), Lyses paraffin (grade No. 5 manufactured by Kokonoe Electric Co., Ltd.) (hereinafter referred to as Lyses paraffin), Shift paraffin (5408R Nichika Seiko Co., Ltd., hereinafter referred to as Shift paraffin), protective film LG#88 ブラツク (Kanae Paint Co., Ltd.) ( The solubility of the following protective film 88)] was evaluated. The evaluation was performed by adding a small amount of the substance to be removed to various cleaning agents maintained at 25° C., and visually observing the solubility after leaving to stand for 5 minutes. In addition, when the substance to be removed was the protective film 88, a protective film that was applied to the lens for evaluation and then dried for one day was used.

Abstract

The present invention provides a cleanser composition which is used for removing fixing agents and protecting films used in processes for polishing optical articles such as lenses and has high cleansing powers against the fixing agents and the protecting films without using halogen-based solvents, fluorine-based solvents and aromatic solvents against which affections are feared. This cleanser composition is characterized by comprising 75 to 25 wt. % of an alkylene glycol alkyl ether such as dipropylene glycol monomethyl ether or dipropylene glycol dimethyl ether and 25 to 75 wt. % of a 10 to 15C cycloparaffin such as cyclodecane, cycloundecane or cyclododecane.

Description

technical field [0001] The present invention relates to a cleaning composition for removing a fixing agent or a protective film used in the manufacture of optical articles such as lenses and prisms. Background technique [0002] When manufacturing optical articles such as lenses, it is necessary to polish the surface of optical substrates such as glass substrates. In this polishing step, although the optical substrate is fixed on the holding table for polishing, a fixing agent made of paraffin, pitch, or the like is used when fixing the optical substrate on the holding table. [0003] In addition, when polishing the other surface after one surface is polished, in order to protect the polished surface, a masking agent composed of phenolic resin, acrylic resin, etc. is applied to form a protective film. In addition, after the polishing process is completed, these fixing agents or protective films are removed from the optical substrate using a cleaning agent, and the polished ...
