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 for cleaning the surface of decorative rubber used for handrails of passenger conveyors, interior decoration items, etc. . [Background of the Invention] Decorative rubber is used in a wide variety of applications, including handrails for passenger conveyors and interior decoration products, because it is easy to dye and has good weather resistance. Since the cosmetic rubber used for such purposes is constantly exposed to human hands, the surface of the cosmetic rubber needs to be cleaned regularly.

Conventionally, detergents that use water as a solvent and a surfactant mixed therein, and detergents that are made of silicone emulsions have been used as cleaning agents for cleaning the surface of cosmetic rubber. However, these cleaning agents do not have a sufficient cleaning effect on strong stains such as hand oil and cigarette smoke.

Furthermore, if a relatively weak solvent such as alcohol such as ethyl alcohol is used to clean the surface of the cosmetic rubber, it is possible to remove stains from the surface of the cosmetic rubber, but the disadvantage is that it removes the luster of the surface of the cosmetic rubber. was there.

[Purpose of the invention]

An object of the present invention is to provide a cleaning agent that can remove dirt from the surface of rubber, such as decorative rubber, without damaging its gloss and color.

[Summary of the invention]

The present inventor previously filed an application for a detergent containing polyethylene glycol, an anionic surfactant, and an amine oxide surfactant as main components as a detergent for cosmetic rubber.

This cleaning agent has a superior cleaning effect compared to commercially available cleaning agents for cosmetic rubber. Therefore, based on the components of the previously applied cleaning agent, the present inventors have intensively studied the combination of components that will further improve the cleaning power without affecting the gloss and color of the cosmetic rubber. As a result, it was discovered that when ethyl alcohol was added to polyethylene glycol, anionic surfactant, and amine oxide surfactant, the detergency was enhanced without affecting the luster and color of the cosmetic rubber.

Furthermore, in the present invention, when an imidacilline type amphoteric surfactant and a cationic cellulose derivative are added in addition to ethyl alcohol, the imidacilline type amphoteric surfactant and the cationic cellulose derivative form a complex salt, and this complex salt is used for cleaning treatment. It has been found that the rubber surface formed in the form of a film can be made glossy, has an antistatic effect, and can prevent dust from adhering to the surface.

The present invention has been achieved based on these findings. The second invention is a detergent containing an imidacillin type surfactant and a cationic cellulose derivative in addition to the ingredients absent in the first invention.

In the present invention, the polyethylene glycol preferably has an average molecular weight of about 180 to 220. As the anionic surfactant, α-olefin sulfonated products are preferred, and sodium α-olenoinsulfonate is particularly effective. Dimethylalkylamine oxide is particularly effective as an amine oxide surfactant, and 2-alkyl-N-carboxylene methyl-N-hydroxyethylimidazolinium betaine is effective as an imidacillin surfactant. The cationic cellulose may be any material that can form a complex salt with the imidaline type surfactant, for example hydroxyethyl cellulose.
Mention may be made of 2-hydroxypropyltrimethylammonium chloride ether.

Considering that the ratio of polyethylene glycol and ethyl alcohol in the cleaning agent is almost the same, and that ethyl alcohol provides cleaning power and does not affect the gloss and color of the cosmetic rubber surface, the ratio in the solvent is 10
~30% by volume is desirable. The cleaning agent does not necessarily need to contain water as a solvent, but it is desirable to avoid containing ethyl alcohol as mentioned above during use. From this point, approximately twice the amount of ethyl alcohol, preferably 40 to 60%, is added to the solvent in advance or at the time of use.
It is preferable to contain % by volume of water as a solvent.

The weight ratio of the amine oxide surfactant, imidacillin type surfactant and cationic cellulose to the anionic surfactant is preferably about 1/4.

It is common for anionic surfactants to be added in an amount of 8 to 12% by weight to solvents containing water. It is desirable to add 2 to 3% by weight of each.

Polyethylene glycol (average molecular weight 180-220
) Each of the following components (1) to (4) was added to a solvent consisting of 25% by volume ethyl alcohol, 25% by volume water, and 50% by volume, and mixed to obtain a homogeneous solution.

Sodium α-olefin sulfonate 10% by weight Dimethylalkylamine oxide 2.5% by weight 2-alkyl-N-carboquinemethyl-N-hydroxyethylimidazolinium betaine 2.5% by weight Hydroxyethylcellulose-2-hydroxypropyltrimethylammonium Chloride ether 2.5% by weight The handrail of the passenger conveyor has been in operation for 8 years and is extremely dirty, red and blue 1. The cleaning agent of this example, a commercially available cleaning agent consisting of water and a surfactant, silicone emulsion, polyethylene glycol, α- Four types of cleaning agents (comparative products) consisting of sodium olefin sulfone TS and dimethylalkylamine oxide were soaked in paper towels, the stains were wiped off, and the state of removal of the stains was judged according to the following criteria. did.

0230 Dirt completely falls off within 30 seconds ○: Dirt completely falls off within 1 minute △: Dirt completely falls off within 1 to 3 minutes ×: Dirt completely falls off after 3 minutes or more 1
As shown.

Table 1 Furthermore, even when the product of this example was allowed to penetrate into the six types of cosmetic rubbers mentioned above for 24 hours, the gloss and color of the surface were not affected.

゛Unfortunately, Q-signature agent is effective not only for cleaning the rubber surface of the man conveyor, but also for cleaning the rubber surface of makeup rubber temples, where oils from people's hands and the oils of the music tend to adhere. It is.

According to the first invention, it is possible to efficiently remove dirt without damaging the color or luster of the rubber surface such as IE rubber, and according to the second invention, the first invention In addition to this effect, it can give the rubber a photonized σ11 gloss, and also has the effect of preventing dust from sticking due to antistatic properties.
