DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor polish composition for protecting a floor and providing gloss for maintaining an aesthetic appearance.

[0002]

2. Description of the Related Art Conventionally, many materials such as tatami mats and carpets have been used for flooring materials in houses. Therefore, plastic and wood-based materials are increasing. In particular, wooden flooring materials tend to be preferred because of their high interior properties. However, wooden flooring materials are usually painted on the surface for makeup and protection, but since the scratches occur with walking and moving furniture, the gloss originally possessed tends to decrease. .

[0003] Therefore, wax products have been used as a care agent for preventing the occurrence of scratches and restoring luster. Wax products are divided into those mainly composed of waxy substances such as carnauba and those mainly composed of synthetic resin polymers. The former, which is applied to the floor surface and buffed after application to give it a gloss, is troublesome, and has the disadvantage that the formed film is lipophilic and dirt is easily adsorbed. The latter was launched to solve this shortcoming. This is applied with a cloth, sponge, etc., and is easy because the synthetic resin forms a glossy film by drying. Was bad. In addition, since a thick-coated portion or the like is not easily removed, it is necessary to use a special release agent for removal.

[0004] Further, recently, floor cleaning and polishing agents capable of polishing and cleaning at one time have been put on the market. A typical floor cleaning polish composition is disclosed in JP-A-6-7340.
No. 0, JP-A-6-108011 and the like. These are obtained by dispersing a wax emulsion or a polymer emulsion in an aqueous medium, and further adding a detersive surfactant, a cleaning aid, a solvent, and the like. By cleaning the floor surface with these floor cleaning and polishing agents, it is possible to remove stains and polish at once.

[0005] On the other hand, the quality of gloss is a problem not only in the properties of the polymer or wax forming the film on the floor, but also in how uniform the film can be formed, that is, how uniformly the agent can be applied. Conventionally, a leveling agent has been added to a floor polish for such a purpose. As the leveling agent, a surfactant is generally used as disclosed in JP-A-59-206476. However, when a surfactant is added, the surfactant remains in the dried film, so that there is a problem that the water resistance of the film is reduced. The improvement of the leveling property is described in Japanese Patent Publication No. Hei 6-23335 and Japanese Patent Laid-Open No. Hei 6-9323.
Examples thereof include polyoxylen straight-chain aliphatic alcohols and polyoxylene branched aliphatic alcohols disclosed in, for example, Japanese Patent Publication No. 2 (1993) -214, and none of the flooring materials such as a wooden floor and a vinyl tile floor have a good leveling property.

[0006]

2-hydroxyethyl acrylate, etc.), acrylamide,
Examples include methacrylamide and dimethylacrylamide.

Of these, methacrylic acid, acrylic acid,
Alkyl acrylate, alkyl methacrylate, styrene and the like are particularly preferred. Further, the polymer emulsion is preferably a hydrosol emulsion treated with a monovalent alkali metal.

It is preferred to contain.

[0013] This water-insoluble polymer emulsion of the composition of the present invention has properties that vary greatly depending on the monomer composition. In the case of constituting the above-mentioned monomer, the amount of a monomer such as styrene and methyl methacrylate is increased in order to improve glossiness. Since the refractive index of a monomer polymer such as styrene and methyl methacrylate is high, the glossiness is improved. In the case of easily peeling off with an alkaline cleaning agent or the like, the amount of an ethylenically unsaturated carboxylic acid monomer such as methacrylic acid is increased. Further, in addition to these monomer constitutions, other monomers are copolymerized in order to adjust the minimum film-forming temperature (MFT) and the glass transition point (Tg) of the water-insoluble polymer emulsion. That is, the composition of the monomer is a glossy monomer, an alkali-soluble monomer,
It is preferable to use three or more Tg adjusting monomers.
In the invention described in claim 1, the amount of the polymer emulsion in the composition is 1 to 30% by weight, preferably 5 to 20% in terms of solid content. According to the second aspect of the present invention, 2 to 20% by weight, preferably 7

The water-insoluble polymer emulsion of the present invention is prepared by adding the above-mentioned ethylenically unsaturated monomer which is insoluble or hardly soluble in water and a surfactant (anionic or nonionic) as an emulsifier to water as a dispersion medium. It is obtained by carrying out radical polymerization with a water-soluble polymerization initiator at a reaction temperature of 40 to 90 ° C. A chain transfer agent is used in this emulsion polymerization. As a chain transfer agent,
Thioglycolates, methyl halides, mercaptans, polymercaptans, polyhalogens and the like are used, but thioglycolates are most preferred. In this case, the polymerization reaction is initiated in the micelle layer of the emulsifier, and the resulting polymer is obtained as a stable suspension (commonly referred to as an emulsion or emulsion) due to the presence of the emulsifier. It can be used in (emulsion) state.

Further, the mixing ratio of the polymer emulsion and the alcohol is preferably 10/1 to 100/1 in terms of solid content. If the compounding amount is less than 0.01% by weight in the composition, there is a drawback that the composition lacks leveling properties and cannot be applied uniformly. If the amount is more than 5% by weight in the composition, there is a disadvantage that the water resistance is reduced.

Most preferred are C12-14 secondary alcohols or polyoxyethylene (EO 5 mol) C12 alkylamines. The compounding amount is preferably 0.2 to 2% by weight in the composition. Further, the mixing ratio of the water-insoluble polymer emulsion / leveling agent is 10/1 to 50/1 in terms of solid content, and preferably 20/1 to 30/1. If the compounding amount is less than 0.2% by weight in the composition, there is a drawback that the composition lacks leveling property and cannot be applied uniformly. When the amount is more than 2% by weight in the composition, there is a disadvantage that the gloss is reduced.
