Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a self-leveling material for producing a horizontal floor in a building, and more particularly to an improved setting delay by a thickener and a dispersant used for imparting self-leveling properties. The present invention relates to a composition for a self-leveling material.

[0002]

2. Description of the Related Art
Cellulose derivatives such as methylcellulose and hydroxyethylcellulose have been used as thickeners together with dispersants to improve self-leveling properties. However, when these organic admixtures are used, there is a problem that a hydration reaction of the hydraulic powder is suppressed, and a setting delay is caused. In view of such problems, development of a composition for a self-leveling material excellent in initial strength development is desired.

[0003]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to improve the above problems, and as a result, have developed excellent strength by using a specific water-soluble polymer and a dispersant in combination. The composition for self-leveling material was completed.

That is, the present invention is a composition for a self-leveling material, comprising the following components (A) and (B). Component (A): a water-soluble polymer having an adsorption property to cement of less than 10%. Component (B): a copolymer obtained by polymerizing a monomer (a) represented by the following general formula (1) and a monomer (b) copolymerizable therewith.

[0007] Conventional thickeners such as cellulose derivatives are strongly adsorbed on the surface of the hydraulic powder and hinder the contact between the powder and water, thereby inhibiting the hydration reaction. Therefore, a water-soluble polymer (non-adsorption type water-soluble polymer) having a small adsorption property to hydraulic powder as used in the present invention is effective as a thickener. Furthermore, in the present invention, it has been found that the coagulation delay can be synergistically reduced by using in combination with a dispersant having an unprecedented high dispersing effect.
