Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a polish composition. More specifically, there is provided a polishing composition comprising an aliphatic or alicyclic isocyanate and an aqueous dispersion or emulsion of a urethane resin formed from an aliphatic polyester or polyether having a hydroxyl group. , A black polish mark resistance, a scuff resistance, an abrasion resistance, and at the same time a glossing agent composition satisfying gloss, leveling properties and the like.

[Prior Art] Among the polishing agents, the classification of polishing agents for floors is in JFPA (Japan Floor Polish Industry Association) Standard-OO. Mainly used as a polish for floors for business use, and also occupying an important position for household use are the water-based non-buffable type shown in this standard, followed by the semi-baffle type. Is known from many. For example,
Japanese Patent Publication No.44-24407, Japanese Patent Publication No.49-1458,
Cosmetic Chemical Specialties, 61 (9), 86 (1985) etc. disclose floor polishes consisting of acrylic copolymer emulsions, polyethylene wax emulsions, alkali soluble resins, plasticizers, etc. Is.

Further, a polishing agent containing an aqueous polyurethane emulsion has been developed for the purpose of obtaining a slip resistance which cannot be obtained by a conventional polishing agent (Japanese Patent Publication No. 53-225).
No. 48).

From the past, efforts have been made to improve the performance of floor polishes even a little. For example, it is the main component of the polish, and the modification of the acrylic copolymer that affects the properties of most of the polish, and the modification of polyethylene wax to improve the black heel mark resistance, etc. Various studies have been conducted. However, these polish components alone do not affect the properties of the polish alone, but they affect each other in a complicated manner and cannot be considered in a unified manner. For example, if you improve the black heel mark resistance, the gloss will decrease.
Alternatively, the slip resistance is lowered, and if the wear resistance is increased, the peelability is deteriorated.

[Problems to be solved by the invention] In a place with a large number of pedestrians such as a large supermarket, a department store, a hall (called heavy walking), the polishing agent is greatly worn, the gloss is significantly reduced, and the black heel mark resistance is high. ， The scuff resistance is poor, and as a result, a special polisher must be used for peeling and a new polish must be applied, which requires a great deal of cost.

On the other hand, Japanese Examined Patent Publication No. 53-22548 provides a polishing agent containing an aqueous emulsion of polyurethane for the purpose of obtaining a slip resistance which cannot be obtained by a conventional polishing agent. However, when the polyurethane aqueous emulsion specifically described in the examples of this patent is used, the drying property is poor, and the acrylic copolymer emulsion can be applied although it can be applied to a buffable type polish. It cannot be applied to non-buffable type and semi-buffable type polishes which are the main components. Further, there is a defect that leveling is poor when applied and a smooth film is not formed.

Therefore, the present invention improves the conventional polishes having an acrylic copolymer emulsion as a main component, particularly, the black heel mark resistance and the abrasion resistance, and at the same time, the drying property of Japanese Patent Publication No. 53-22548. The present invention provides a polish composition for improving leveling resistance.
