Abstract

PURPOSE:A cleaning and polishing agent having improved cleaning ability and polishing effect without damaging the surface of decorative rubber, obtained by adding specific three surface active agents to an aqueous emulsion of dimethylsilicon oil. CONSTITUTION:Dimenthylsilicone oil is emulsified in water as a solvent, and (A) 4-8wt% surface active agent of alkylbenzenesulfonate type, (B) 2-6wt% surface active agent of polyoxyethylene fatty acid amide type, and (C) 1-3wt% carboxy betaine type surface active agent are added to the emulsion, to give the desired polishing agent for decorative rubber.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a cleaning polishing agent suitable for use in cosmetic rubber.

[Background of the invention]

In general, decorative rubber is used in a wide variety of applications, such as handrails for passenger conveyors and interior decorations, for reasons such as ease of dyeing and excellent weather resistance.

Currently, commercially available neutral detergents such as dimethyl silicone emulsions are used for cleaning and polishing cosmetic rubber.

However, neutral detergents had no cleaning effect on strong stains such as hand oil and cigarette smoke, and in particular had no polishing effect at all. On the other hand, dimethyl silicone emulsions have a polishing effect but have a drawback of extremely weak cleaning power. Incidentally, when a solvent having a relatively weak dissolving power such as ethyl alcohol is used, although the cleaning power is excellent, there is no polishing effect and there is a drawback that the surface of the decorative rubber is corroded.

[Purpose of the invention]

An object of the present invention is to provide a cleaning polishing agent that can remove dirt without damaging the surface of decorative rubber and can also give it a glossy appearance.

[Summary of the invention]

The present inventor first used polyethylene glycol, ethyl alcohol, and water as the main solvent, and added an anionic surfactant, an amine oxide surfactant, an imidacillin type amphoteric surfactant, and a cationic cellulose derivative as main components. However, although this cleaning agent had excellent cleaning power and did not attack the surface of decorative rubber, it had a rather low polishing effect.

Therefore, in order to increase the polishing effect, the present inventor considered adding dimethyl silicone oil, which has the most polishing effect, to the above-mentioned cleaning agent. However, since ethyl alcohol and polyethylene glycol are present in the royal solvent, the dimethyl silicone oil separates no matter what emulsifier is used, making it impossible to add a polishing effect to the cleaning agent.

For this reason, the present inventor considered emulsifying dimethyl silicone oil using water as a solvent and mixing a surfactant into the oil.

Previously, we introduced an alkylbenzenesulfonic acid type surfactant that has strong cleaning power, and a polyoxyethylene fatty acid amide type that emulsifies dimethyl silicone oil without being canceled out by the alkylbenzenesulfonic acid type surfactant. Discovered a surfactant.

By adding a carboxybetaine type surfactant to this, the cleaning effect could be significantly increased.

[Embodiments of the invention]

One implementation of the present invention will be described below. 25C dimethyl silicone oil with a viscosity of 800 to 1200
Add 55 to 73 weight% of water to 30% by weight, 2 to 6% by weight of polyoxyethylene, 4 to 8% by weight of linear sodium argylbenzene sulfonate, and 2 to 3 parts of carboxybetaine interfacial binder. , mix well and stir
A white homogeneous emulsion is obtained.

red, evening, black, and dark blue, which have become extremely dirty and have lost their luster due to ht operation.
The cosmetic rubber of Enji's 5 types, 8crnX15crn, was used as the test product, and (A) neutral detergent, (B) silicone emulsion, (C) the cleaning agent proposed earlier, and (D) cleaning polishing agent according to this example. The four types were dipped in paper towels, the test items were wiped off, and then thoroughly wiped with a tumbled cloth. As a result, the state of removal of the stain and the appearance of the color were judged according to the following criteria.

First, in the dirt removal state, if the dirt has completely fallen off within 30 seconds, ◎, if the dirt has completely fallen off within 1 minute, ○, if the dirt has completely fallen off within 1 to 3 minutes. △, × if the dirt has completely fallen off for more than 3 minutes
On the other hand, if the appearance of gloss is significant, it is ◎, if it is slightly glossy, it is ○, if it is not glossy at all, it is Δ, and if it is not glossy at all, it is ×. It can be expressed as a second light.

(2) As is clear from this table, the cleaning polishing agent (D) according to this example has both superior cleaning power and polishing effect compared to the other agents (A) to (C). Also cleaning polishing agent (1))
The test pieces with the above five glazes were soaked for 24 hours, but the surface of each test piece was not corroded. Furthermore, cleaning polishing agent (D
) does not separate from the dimethyl silicone oil even after being left at 25C for 4 weeks, and by adding a carboxybetaine type surfactant, it is possible to prevent static charging of the cosmetic rubber and obtain a bactericidal effect.
