Description

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 floor materials of houses. However, in recent years, house dust and ticks derived from tatami mats and carpets tend to cause allergies. , Plastic and wood 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. . 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 coating is easy because the synthetic resin forms a glossy film by drying after coating, but the formed film is stronger than the former, so a special release agent had to be used for removal.

[0003] Furthermore, 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. However, in any of the above-mentioned agents, formation of a film on the floor surface is equivalent, and there has been recognized a problem that peeling and cracking from the floor surface are likely to occur depending on the properties of the film.

[0004]

In order to solve this problem, it is common to add a carboxylic acid ester type plasticizer such as dibutyl adipate or dibutyl sebacate in order to improve the flexibility of the film. However, in the case of synthetic resin polymer polish, there is a new problem that the lipophilicity is lower than that of wax, so the stable compoundability in the system is inferior depending on the type of plasticizer, and the expected effect cannot be exhibited. It recognized. From this situation, the problem of the present invention is:
An object of the present invention is to provide a floor polish composition which has a polish property to a floor surface, improves cracking and peeling of a film after drying, and has excellent storage stability and durability of a coating film.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have found a plasticizer which can improve the cracking and peeling of the film and has excellent blending stability. We have completed this study. That is, the present invention relates to a floor polish composition containing a water-insoluble polymer emulsion obtained by emulsion polymerization of at least one ethylenically unsaturated monomer, wherein oxy is used as a plasticizer for improving the flexibility of a film. A floor polish composition comprising an acid ester and / or an unsaturated dicarboxylic acid ester.

[0006]

Embodiments of the present invention will be described below. The floor polish composition of the present invention contains a polymer emulsion in order to form a film on the floor and impart gloss. A typical example of the film-forming polymer emulsion is one obtained by emulsion polymerization of one or more polymerizable monomers of an ethylenically unsaturated monomer. Examples of such an ethylenically unsaturated monomer include those having a carboxyl group such as acrylic acid, methacrylic acid, fumaric acid, itaconic acid, crotonic acid, and maleic acid, and others, alkyl acrylate, alkyl methacrylate, styrene, vinyl toluene, and vinylidene chloride. , Acrylonitrile, methacrylonitrile, acrylamide, methacrylamide and the like. Among them, acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, styrene and the like are preferable.

Further, the polymer emulsion obtained by emulsion polymerization may be appropriately treated with a monovalent alkali metal. In the present invention, in particular, a water-insoluble polymer emulsion obtained by emulsion polymerization of an ethylenically unsaturated monomer having at least one carboxyl group and one or more other polymerizable monomers contains a carboxyl group. This carboxyl group is most preferable because it has an effect of easily peeling off the coating film when washed with a weak alkaline detergent or the like at the time of repainting. The compounding amount of the polymer emulsion in the composition of the present invention is 5 to 25%, preferably 7 to 15% in terms of solid content.

[0008] Examples of the plasticizer used in the present invention include an aliphatic oxyacid ester and an aliphatic unsaturated dicarboxylic acid ester. Specific examples include esters such as lactic acid, tartaric acid, citric acid, ricinoleic acid, fumaric acid, and maleic acid, and particularly preferred are acetyltributyl citrate, dibutyl fumarate, and dibutyl maleate. The blending amount of the plasticizer is generally about 4 to 10% by weight of the blending amount of the polymer emulsion (in terms of solid content).
Therefore, the amount of the polymer emulsion in the composition (in terms of solid content) is 5 to 25% by weight. Therefore, the amount of the plasticizer in the composition is 0.20 to 2.5% by weight, preferably 0.25 to 2.0% by weight is preferred. When the compounding amount does not reach the above range, the flexibility of the dried film is insufficient, and when it exceeds the above range, no remarkable increase in the effect is observed, which is not economically preferable.

The hydrophilic solvent is not particularly limited, but is preferably an alkylene glycol ether-based solvent. Particularly preferred examples include ethyl carbitol, acetyl ethyl carbitol, butyl carbitol, acetyl butyl carbitol, texanol, dimethyl carbitol, diethyl carbitol, and methyl ethyl carbitol. The content of the hydrophilic solvent in the composition of the present invention is 3 to 20% by weight, preferably 5 to 10% by weight.
