Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to polish compositions. More specifically, it is a polish composition comprising an aqueous dispersion or emulsion of a urethane resin produced from an aliphatic or alicyclic isocyanate and an aliphatic polyester or polyether having a hydroxyl group, This invention relates to a polishing agent composition that improves black heel mark resistance, scuff resistance, abrasion resistance, and satisfies gloss, leveling properties, etc. at the same time.

[Prior art] Among polishing agents, floor polishing agents are classified according to JFPA (II
This floor is in Standard-00 (Polish Industry Association). The water-based non-buffable type specified in this standard, followed by the semi-bubble type, is the mainstream as a floor polish for commercial use, and is also occupying an important position for household use. For example, Special Publication No. 44-24407, Special Edition 11a49-145
No. 8.

Cosmetic Chemical 5peci
Alties, Gl(9), 8B (1985) and others disclose a floor polish consisting of an acrylic copolymer emulsion, a polyethylene wax emulsion, an alkali-soluble resin, a plasticizer, and others. .

In addition, a polishing agent containing an aqueous polyurethane emulsion has been developed with the aim of providing slip resistance that cannot be obtained with conventional polishing agents (4 ¥ Publication 53-22).
No. 548).

Efforts have been made in the past to improve the properties of floor polishes. Various tests have been carried out, such as modification of copolymers, modification of polyethylene wax to improve black heel mark properties, etc. However, each of these polishing subcomponents does not affect the properties of the polishing agent on its own, but they interact with each other in a complex manner, and cannot be considered unifiedly. If you do so, the gloss will decrease or the slip resistance will decrease.

If the abrasion resistance is increased, the releasability becomes worse, and so on.

[Problems to be solved by the invention] In places with a lot of foot traffic (so-called heavy foot traffic) such as large supermarkets, department stores, and halls, the polishing agent is subject to severe abrasion, resulting in a significant decrease in gloss, and furthermore, the black heel mark resistance is reduced. Also, the scuffing resistance is poor, and as a result, it must be removed using a special remover and a new polishing agent must be applied, which requires a large amount of expense.

On the other hand, Japanese Patent Publication No. 53-22548 provides a polishing agent containing an aqueous emulsion of polyurethane for the purpose of obtaining slip resistance that could not be obtained with conventional polishing agents. However, when the aqueous polyurethane emulsion specifically described in the example of this patent is used, it has poor drying properties, and although it can be applied to a fable type polish, it cannot be used as an acrylic copolymer emulsion. It cannot be applied to non-buffable and semi-puffable type polishes, which are the main ingredients, and has drawbacks such as poor leveling and failure to form a smooth film when applied.

Therefore, the present invention aims to improve the black heel mark resistance and abrasion resistance of the conventional polishing agent containing an emulsion of an acrylic copolymer as a main component, and at the same time improve the drying properties as described in Japanese Patent Publication No. 53-22548. , provides a polish composition intended to improve leveling resistance.

[Means for Solving the Problems] In order to achieve the above object, the inventors of the present invention continued their intensive research, and as a result, they completed the present invention.

That is, the present invention provides an aliphatic or alicyclic isocyanate having 8 to 38 carbon atoms and an aliphatic polyester having an average molecular weight FJ of 500 to 5,000 and having a hydroxyl group, or an aliphatic polyether having an average molecular weight of 200 to 6,000 and having a hydroxyl group. This is a polish composition characterized by containing an aqueous dispersion or emulsion of a urethane resin produced from.

Methylstyrene, acrylic acid, methyl acrylate, ethyl acrylate, methacrylic acid, methyl methacrylate, ethyl methacrylate, methyl methacrylate, hexyl acrylate, 2-ethyl-hexyl acrylate, vinyl acetate and co-π of these types Monufac may be used alone or as a mixture (Japanese Patent Publication No. 44-24409), and may also be a metal cross-linked type obtained by adding a polyvalent metal chelating agent.

A large number of aqueous urethane resin dispersions and emulsions, especially the latter, are known. The aqueous urethane resin dispersion or emulsion that can be used for undeveloped 11 is extremely limited. i.e., one or more addition reaction products prepared from an aliphatic or cycloaliphatic isocyanate and an aliphatic diol, preferably also with the addition of a small amount of an aliphatic diamine as a chain extender. Reactants are useful.

When looking at this substance from one aspect, it is preferable that it has the following properties.

■ Non-yellowing type. If it is the yellowing type, it will spoil the aesthetic appearance of the floor after it is applied to the floor.

(The average particle diameter is preferably 1500 angstroms or less, preferably 1000 angstroms or less, 1 soo
If the average particle size is more than 5,000 angstroms, the gloss of the polishing agent tends to decrease, and if the average particle size is more than 5,000 angstroms, it is visually confirmed that there are many lumps on the paint film. can do.

■Drying is 'i'-<, the surface is not sticky.

Suitable diols are polyesters formed from short-chain aliphatic diols with prime numbers 2 to 6 (e.g. adipic acid) or aliphatic polyethers containing hydroxyl groups, e.g. ethylene oxide, propylene oxide.

Or it is a polyether prepared by polymerization of tetrahydrofuran. Generally, low molecular weight diols such as ethylene glycol and 1.1li-hexanediol are used directly in the production of urethane resins. These are useful for chain extension and denaturation.

The aqueous dispersion or emulsion of the urethane resin mentioned above is available on the market. For example, there is Neoret from Polyvinyl Chemical Industries, Ltd. For example, R-98
