Description

  The present invention is applied to a flooring material such as a chemical flooring material, a stone-based flooring material, and a wooden flooring material and dried to form a film, which is used for maintaining the beauty of the flooring material and protecting the flooring material. The invention relates to an aqueous floor polish composition.

  For flooring of buildings such as wooden flooring, synthetic resin flooring, stone flooring, concrete, etc., an aqueous floor polishing agent composition is applied for the purpose of maintaining the beauty of the flooring and protecting the floor. Maintenance. This aqueous floor polish composition remains as a dry resin film after volatilization of water, and imparts various performances such as gloss, stain resistance, and scratch resistance to the floor surface. Plasticizers and leveling agents are added to the aqueous floor polish composition to improve the various properties of the film, such as the flexibility of the dry resin film, adhesion to the flooring during film formation, and leveling properties. Is done. Conventionally, tributoxyethyl phosphate has been mainly used as a plasticizer and leveling agent (hereinafter simply referred to as a plasticizer) for an aqueous floor polish composition.

  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.

  Then, this invention makes it a subject to provide the polish agent composition for aqueous floors excellent in environmental adaptability and a film | membrane characteristic.

  As a result of repeated investigations on many plasticizers, the present inventors have found that propylene glycol fatty acid esters, particularly propylene glycol monofatty acid esters, have the same or better performance as tributoxyethyl phosphate as plasticizers. The present invention has been completed.

  That is, this invention provides the polish agent composition for aqueous floors characterized by containing propylene glycol fatty acid ester, and solves the said subject.

  According to this invention, since the plasticizer component contained does not contain phosphorus and has a performance equal to or better than that of tributoxyethyl phosphate, it is suitable for an aqueous floor that achieves both environmental adaptability and excellent film properties. It can be set as a polish composition.

  In this embodiment, the propylene glycol fatty acid ester is preferably at least one propylene glycol monofatty acid ester represented by the general formulas (1) to (3).
