多く用いられるようになってきている。(Prior Art) In recent years, a wall waterproofing method using a synthetic resin emulsion containing an alkyl acrylate polymer for waterproofing a wall has been actively performed. As the synthetic resin emulsion containing an alkyl acrylate polymer used in the wall waterproofing method, a soft resin having an extremely low glass transition temperature is generally used so that cracks and cracks do not occur even when applied thickly. Therefore, since the coating material using the synthetic resin emulsion containing the alkyl acrylate polymer as a binder is sticky as it is, the surface is apt to be easily soiled. Therefore, generally, a finish coating material is applied on this coating material to eliminate stickiness of the surface and to make up the surface of the coating material. Recently, a solvent-based isocyanate-curing finish coating material typified by acrylic urethane has been widely used as a decorative material.

いと言う致命的な欠陥があった。(Problems to be Solved by the Invention) Solvent-based isocyanate-curing finish coating materials typified by acrylic urethane are generally wall surfaces using a synthetic resin emulsion containing the aforementioned alkyl acrylate polymer as a binder. Poor adhesion to waterproof coating. In particular, there is a fatal defect that when the coating material surface is wet with a paint thinner, the isocyanate-curing type finish coating material typified by acrylic urethane does not dissolve and swells and floats up from the intermediate coating waterproof material layer and does not return to the original state.

成するに至った。(Means for Solving the Problem) Then, as a result of intensive studies for solving the problem, the present inventors have found that, among functional groups capable of reacting with isocyanate, an acrylic acid ester or methacrylic acid having a hydroxyl group is particularly contained. It was found that the adhesiveness between the waterproof material layer and the finish coating material layer is remarkably improved by using a synthetic resin emulsion obtained by copolymerizing an ester with an alkyl acrylate ester as a binder for the intermediate coating waterproof material layer of the wall waterproof coating material. The invention was completed.

An acrylic acid alkyl ester having 10 alkyl groups is used. That is, in the copolymer of alkyl acrylate having an alkyl group having 4 or less carbon atoms,
(A) The glass transition temperature is not so low that the flexibility of the target coating film cannot be obtained, and (b) the alkali resistance of the coating film is inferior. On the other hand, alkyl having 10 or more carbon atoms Copolymers of alkyl acrylates having a group generally have a carbon number of 4 to 4 in the field because of the high glass transition temperature and the inability to obtain the desired flexibility of the coating film.
Due to the use of alkyl acrylates having 10 alkyl groups.

水性が低下し防水機能の低下を招く。The amount of alkyl acrylate as a monomer constituting the polymer of the present invention is 60 to 98% by weight, preferably 90 to 95% by weight, based on the total monomers. When the amount of the alkyl acrylate is less than 60% by weight, the wall waterproof coating material using the synthetic resin emulsion as a binder loses flexibility and deteriorates the waterproof function. The amount of acrylic acid ester or methacrylic acid containing a hydroxyl group is from 1 to 5% by weight, preferably 2 to 4% by weight in the case of an acrylic acid ester containing a hydroxyl group, and in the case of a methacrylic acid ester containing a hydroxyl group. It is 3 to 5% by weight. When the amount of the acrylic acid ester or methacrylic acid ester having a hydroxyl group is less than 1% by weight, the cross-linking point with isocyanate decreases and the adhesiveness between the waterproof material layer and the finishing material layer using the synthetic resin emulsion as a binder. Cause a decrease in
Further, when the amount of the acrylic acid ester or methacrylic acid ester having a hydroxyl group is 5% by weight or more, the water resistance of the wall waterproof coating material using the synthetic resin emulsion as a binder is lowered and the waterproof function is lowered.

ない量の共重合で密着性向上が期待されるからである。Among the acrylic acid ester and the methacrylic acid ester having a hydroxyl group, the acrylic acid ester is preferable. Acrylic ester is generally more hydrophilic than methacrylic acid in the same family, and hydroxyl groups are more likely to collect on the surface of the coating film because of better cross-linking efficiency with isocyanate and a smaller amount of copolymerization is expected to improve adhesion.

く改良されるものである。 (Effect of the invention) The middle coat waterproofing material layer of the wall waterproofing coating material of the present invention is mainly composed of a flexible alkyl acrylate obtained by copolymerizing an acrylic acid ester or a methacrylic acid ester having a hydroxyl group capable of reacting with isocyanate. Since the paint uses a synthetic resin emulsion made of a polymer as a polymer constituent monomer as a binder, the adhesion to a solvent-based isocyanate-curable finishing material layer represented by acrylic urethane is remarkably improved.
