The cement composition of the present invention contains an emulsion polymer obtained by polymerizing the compound (A) having the above-mentioned structural formula with another α,β-ethylenic monomer (B). (A) has a type of cationic property that has a different chemical structure from the α,β-ethylenic monomer for imparting cationic property disclosed in Japanese Patent Publication No. 57-49506 mentioned above. It is a reactive emulsifier. For this reason, this compound (
When A) is used, the polymer particles become cationic, and when the composition of the present invention is mixed into cement, Ca in the cement is reduced.
It is thought that the compound (A) is less likely to electrostatically agglomerate with 'IQ-(Oni/) such as I2, Ko, etc., and exhibits even better cement miscibility. β
- Since it can be copolymerized with the ethylenic monomer (B), there are fewer components eluted into the aqueous phase of the emulsion polymer, and when the composition is mixed with cement, there are fewer water-soluble components that inhibit cement hardening. Therefore, it is thought that this is why the early strength and adhesive properties of cement are excellent. Furthermore, compound (A) has a hydroxyl group derived from a glycidyl group existing in the molecule and a quaternary ammonium group that are relatively adjacent to each other via a bond with two carbon atoms, and this bipolar group also has adhesive properties. This is considered to have contributed greatly to the improvement. In addition, α,β-ethylenic monomer (
Examples of B) include methyl (meth)acrylate, ethyl (meth)acrylate, n-butyl (meth)acrylate, 1so-butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, ( (Meth)acrylic acid esters such as lauryl meth)acrylate; esters of maleic acid, fumaric acid, and itaconic acid; monobasic acids such as acrylic acid, methacrylic acid, vinyl sulfonic acid, and vinyltoluenesulfonic acid; Salts; unsaturated dibasic acids such as itaconic acid, fumaric acid, maleic acid and their half esters; salts; acrylamide, methacrylamide,
Amides of α, β-ethylenically unsaturated acids such as maleic acid amide; substituted amides of unsaturated carboxylic acids such as N-methylolacrylamide or methacrylamide, diacetone acrylamide; vinyl acetate, vinyl propionate,
Vinyl esters such as vinyl carboxylate; styrene,
Aromatic vinyl compounds such as vinyl toluene, heterocyclic vinyl compounds such as vinyl pyrrolidone; vinyl chloride, acrylonitrile, vinyl ether, vinyl ketone, vinyl amide, etc.; halogenated vinylidene compounds such as vinylidene chloride, vinylidene fluoride; α- such as ethylene, propylene, etc.
Olefins; monomers having two or more unsaturated bonds in one molecule, such as diallyl phthalate, divinylbenzene, allyl acrylate, and trimethylolpropane trimethacrylate;
Used in one species or in two or more species.

The proportion of compound (A) used is preferably in the range of 0.2 to 10 parts by weight per 100 parts by weight of α,β-ethylenic monocrab (B). If less than 0.2 parts by weight of compound (A) is used, the miscibility of the resulting emulsion polymer with cement, the early strength and adhesion of the cement hardened product will not be sufficiently improved; If the amount exceeds this amount, the viscosity of the resulting emulsion polymer will become extremely high, which is not preferable.
