Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a cleaning agent, and particularly to a cleaning agent suitable for cleaning without damaging the gloss and color of the surface of decorative rubber. [Prior Art] Currently, decorative rubber has the advantages of being easy to dye and having good weather resistance, so it is used in a wide variety of applications, such as handrails for passenger conveyors and interior decorations.

Conventionally, commercially available cosmetic rubber cleaning agents (water mixed with a surfactant) and silicone emulsions have been used to clean this type of cosmetic rubber.

However, the above-mentioned cleaning agents are not effective against strong stains such as hand oil and cigarette smoke, and if a relatively weakly soluble solvent such as alcohol is used,
Although stains can be removed, this method has the drawback of significantly damaging the gloss and deep color of the surface of the decorative rubber.

[Purpose of the invention]

The present invention has been made in view of the above, and its object is to provide a cleaning agent that can thoroughly clean all stains from decorative rubber without damaging the gloss and color of the surface of the decorative rubber.

[Summary of the invention]

A feature of the present invention is that the main component of the cleaning agent is polyethylene glycol mixed with an anionic surfactant and an amine oxide surfactant.

[Embodiments of the invention]

First, we investigated liquid paraffin, which has the ability to clean chlorosulfonated polyethylene, a polymer used in decorative rubber, as a solvent that does not have a negative effect. Although liquid paraffin is effective in cleaning dirt from cosmetic rubber, the results showed that it extracted the pigments from the cosmetic rubber, causing the cosmetic rubber to discolor.

Next, we investigated polyethylene glycol. As a result, polyethylene glycol has the ability to clean cosmetic rubber, yet does not extract pigments from cosmetic rubber.
It has also been found that the polymer of cosmetic rubber is not adversely affected. However, when cleaning cosmetic rubber with polyethylene 7 glycol, the cleaning ability was not very strong, so it took too long to clean.

Therefore, in order to increase the cleaning ability, we mixed a large amount of an anionic surfactant, which is generally the surfactant with the strongest cleaning power, into polyethylene glycol.

However, when only a large amount of anionic surfactant is mixed in, the alkalinity becomes strong, which causes a phenomenon in which the polymer of the cosmetic rubber is attacked when the cosmetic rubber is washed.

Therefore, in the present invention, by adding an anionic surfactant to polyethylene glycol and a neutral amine oxide surfactant that has a synergistic effect on the cleaning ability when added to the anionic surfactant, the cleaning ability is increased and , a cleaning agent that suppresses the increase in alkalinity.

When the stains on the cosmetic rubber were cleaned using this cleaning agent, the stains on the cosmetic rubber could be completely cleaned without damaging the surface adhesive or color of the cosmetic rubber.

Examples will be described below.

Polyethylene glycol 5 with average molecular weight 380-420
5 to 65% by weight, 25 to 35% by weight of polyethylene glycol with an average molecular weight of 3000 to 3700, and 4.5 to 5.5% by weight of sodium α-olefin sulfonate (14 carbon atoms), an anionic surfactant. and dimethylalkylamine oxide (814.5 to 5.5% by weight of carbon atoms), which is an amine oxide surfactant, are completely mixed, heated and dissolved, cooled, and stirred to form a uniform, highly viscous solution. And so.

Next, the blue, red, black, navy blue, and dark blue, which have been operated as Mango/Pair's N'Drail for six years and are extremely dirty.

Six types of cosmetic rubbers (dimensions: 10 m x 20 cm) of Enji were soaked in paper towels with three types of cosmetic rubber cleaning agents currently on the market, silicone emulsion, and the above-mentioned cleaning agent according to the present invention, and cleaned with this to remove stains. We investigated the state of falling off. The results are shown in Table 1.

Table 1/Notes (@ mark; dirt completely falls off within 1 minute ○ mark; dirt falls off completely within 1 to 3 minutes △ mark: dirt completely falls off within 5 minutes or more x mark; 5 As can be seen from the results shown in Table 1, stains do not completely come off even after more than a minute, when the cleaning agent according to the present invention is used, it exhibits good cleaning ability for all types of decorative rubber. Even when it was left on 6 types of cosmetic rubbers for 24 hours, the surface adhesive and color of the cosmetic rubbers were not affected. This is because the alkalinity is suppressed and the cleaning ability of the car is increased.

Note that by adding water to the cleaning agent according to the present invention, the cleaning ability and the viscosity in mg can be adjusted to suit the actual situation.

〔Effect of the invention〕

As explained above, according to the present invention, there is an effect that all stains on the cosmetic rubber can be thoroughly cleaned without damaging the surface adhesive and color of the cosmetic rubber.
