Description

  The present invention relates to a floor surface maintenance and management method that can maintain the aesthetics of a floor surface for a long period of time, is simple and excellent in workability and economy, and a film remover composition used therefor. More specifically, in a method of maintaining and managing a floor surface on which a floor polish film formed by applying and drying at least a floor polish composition is formed on the floor material, the film surface is coated with a film removing agent composition. The present invention relates to a floor surface maintenance and management method characterized by including a step of removing a part of a floor polish film without removing all the overcoated floor polish films, and a film remover composition used therefor .

  Usually, department stores, supermarkets, mass retailers, retail stores, convenience stores, schools, libraries, hospitals, welfare facilities, airport facilities, railway facilities, office buildings, etc., wooden flooring, synthetic resin chemical flooring, concrete and marble On the floor surface such as a stone floor, a film made of a floor finish composition is formed for the purpose of maintaining the beauty of the floor material and protecting the floor surface. The floor finish composition is defined in the definition of “JFPA (Japan Floor Polish Industry Association) Standard-00”, a general term for floor polish test methods.

  In this standard, floor polish compositions are broadly classified into three types, aqueous, emulsifiable, and oily, and in particular, when they are aqueous, they are classified into a polymer type and a wax type. In addition, only the wax type is available for emulsification and oiliness. At present, an aqueous polymer type floor polish composition has become the mainstream, and usually, 4 to 6 layers are applied to the floor surface to form a floor surface film. However, although the time required for coating and drying depends on conditions such as the season, temperature, and humidity, it takes 30 to 60 minutes per layer, so a series of coating operations require a considerable amount of work time. Yes.

  The floor surface (floor polish film) to which the above water-based polymer type floor polish is applied has a glossy aesthetic appearance, but as time passes, abrasion and dirt such as scratches from walking adhere to the aesthetic appearance. Is damaged.

  For this reason, on the floor surface on which the floor polish film is formed, cleaning and rinsing operations using a neutral to alkaline floor cleaner are performed once or twice a month. . When the surface cleaning accumulates dirt that cannot be completely removed, and the desired aesthetics cannot be maintained even if this is repeated, the floor polish film is usually removed at a rate of about once a year. The whole is peeled and removed, and the floor polish composition is newly applied and dried to re-form the floor polish film, and the work of maintaining and managing the aesthetics of the floor surface is performed.

  As such a floor release agent composition used for the removal and removal work for removing the existing floor polish film on the floor surface, a specific water-soluble organic solvent, water-soluble polyacrylic acid, nonionic surfactant, An alkaline resin wax film stripper composition comprising a polyhydric alcohol, an inorganic or organic alkali and water has been proposed as being useful for easily stripping a resin wax film without using a polisher (Patent Document 1). See).

In addition, the release agent for water-based polymer type floor polish mainly composed of specific water-soluble organic solvent, benzyl alcohol and amines has excellent removability of the film of water-based polymer type floor polish, and easy to wipe with water. It has been proposed that it can be used safely without an unpleasant odor (see Patent Document 2).

The component (E) includes hydroxycarboxylic acids such as citric acid, gluconic acid, tartaric acid, malic acid, succinic acid, and lactic acid and / or their salts, nitrilotriacetic acid, ethylenediaminetetraacetic acid, hydroxyethylethylenediaminetetraacetic acid, diethylenetriaminepenta Aminocarboxylic acids such as acetic acid and methylglycine diacetic acid and / or their salts, acrylic acid polymers, maleic acid polymers, acrylic acid-maleic acid copolymers, poly-α-hydroxyacrylic acid and / or their salts And the like, and the like.
Examples of these salts include alkali metal salts, alkaline earth metal salts, ammonium salts, and alkanolamine salts. However, these (E) components may remain in the acid form, or part or all of them. It may be in the form of salt.

  The blending amount of the chelating agent as such component (E) is such that the mass ratio in the composition is (E) / ((A) + (B) + (C)) = 0.005 to 0.5. It is preferable to set within the range. That is, when the mass ratio is less than 0.005, the effect of improving the storage stability of the diluted solution when the composition stock solution is diluted with water is poor. This is because it tends to remain on the floor surface and there is a risk that the increase in gloss when the film is applied will be low. In particular, it is more preferable to set it in the range of 0.01 to 0.3 from the viewpoint that the floor surface remains after removal of the film and the storage stability of the diluted solution is excellent.
