Description

  The present invention is suitable for applying to a flooring material such as a plastic flooring material, a stone-based flooring material, and a wooden flooring material and drying to form a film, maintaining the beauty of the flooring material and protecting the flooring material. The present invention relates to an aqueous floor polish (floor polish) composition to be used.

  Conventionally, with respect to the floor surface of a building, for the purpose of protecting the floor surface and improving aesthetics, maintenance is performed by applying an aqueous floor polish. This floor polish remains as a dry resin film after volatilization of moisture, and imparts various performances such as gloss, stain resistance, and scratch resistance to the floor surface. A plasticizer or a leveling agent is added to the floor polish in order to improve various properties such as flexibility of the dried resin film, adhesion to the flooring material during film formation, and leveling properties. Conventionally, tributoxyethyl phosphate has been mainly used as a plasticizer and leveling agent (hereinafter simply referred to as a plasticizer).

  However, since tributoxyethyl phosphate contains phosphorus in the molecule, there are concerns about its use in terms of contamination in wastewater and the effect on the indoor environment, and high-performance plastics that replace tributoxyethyl phosphate. Application of agents has been sought.

Until now, various compounds have been proposed as plasticizers to replace tributoxyethyl phosphate. For example, as a plasticizer, in Patent Document 1, adipic acid ester, in Patent Document 2, citric acid alkyl ester, in Patent Document 3, specific acrylic polymer, and in Patent Document 4, polyoxyethylene alkyl ether and 2,2,4-trimethyl- A floor polish composition containing 1,3-pentanediol monoisobutyrate has been reported.
