ãè¡šãDETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermosetting aqueous emulsion in which a blocked isocyanate, a polyol and an amine-modified epoxy resin are mixed and dispersed in water. More specifically, the present invention provides blocked isocyanate (i),
Polyether polyol and/or polyester polyol having two or more hydroxyl groups in one molecule
The present invention relates to a polyurethane emulsion particularly suitable for paints, which is obtained by blending (ii) and a reaction product (iii) of an epoxy resin and an amino compound and then emulsifying the mixture. Solutions of compositions consisting of blocked isocyanates and polyols have been used in coatings as one-component compositions with a long pot life. In recent years, in consideration of pollution and various health and safety problems caused by the solvents contained in solvent-based paints, there has been an active shift to emulsion-type resins that use water as a medium. Polyurethane resin paints are no exception, and various efforts have been made to turn them into emulsions. However, polyurethane resins generally have a large cohesive force due to their urethane bonds and are difficult to disperse in water, making it difficult to obtain emulsions with good stability. Conventionally, in order to obtain a urethane resin emulsion with good stability, tertiary amino groups were introduced into the urethane resin and cationized with an acid aqueous solution to make it hydrophilic.After introducing a carboxyl group into polyurethane, an amino compound was A method of making it hydrophilic by using a salt such as an alkali, a method of introducing a polyoxyethylene chain into the molecule to obtain a self-emulsifying resin to make it hydrophilic, and emulsifying it in water. Methods such as adding and emulsifying are being implemented. It is difficult to improve performance because a large amount of hydrophilic parts remain in the coating films obtained from emulsions made by these methods.
Furthermore, when the coating film is immersed in water, the water penetrates into the coating film, resulting in disadvantages such as whitening, swelling, softening, and peeling of the coating film from the object to be coated. As a result of intensive research in order to improve the above-mentioned drawbacks, the present inventors have found that a compound produced by reacting an epoxy resin with an amine is mixed with a blocked isocyanate, a polyether polyol and/or a polyester polyol, and the mixture is emulsified. An aqueous polyurethane emulsion with unprecedented performance could be obtained, leading to the present invention. That is, the present invention is directed to blocked isocyanates (i) having two or more blocked isocyanate groups in one molecule, two or more hydroxyl groups in one molecule, and preferably two or more urethane bonds in some or all of the molecules.
(iii) a product of active hydrogen-containing reaction between a polyether polyol and/or polyester polyol (ii) and an epoxy resin and an amino compound having at least one of the above (i), (ii) and (iii). (ii) and (iii)
Active hydrogen in (i)/blocked isocyanate group in (i) = 0.5 to 1.5 (equivalent) and dispersed in water to provide a thermosetting aqueous emulsion. The present invention improves the adhesion of the coating film to the substrate by containing a reaction product of an epoxy resin and an amino compound in the composition, that is, when the coating film is immersed in water for a long time, Peeling from the base material can be prevented. Furthermore, in the present invention, the tertiary amino nitrogen that can be produced by the reaction between the epoxy resin and the amino compound acts as a catalyst that promotes the reaction between the isocyanate group and the hydroxyl group, thereby lowering the baking temperature of the coating film and reducing the baking temperature. It can shorten the time. After applying and drying the emulsion of the present invention, the cured coating becomes a completely transparent and colorless film.
It does not whiten or dissolve even when immersed in cold water, hot water, or hot alkaline water. The emulsion of the present invention is also useful as a paint that can be applied to metals, glass, ceramics, etc. and baked by heating (130°C to 200°C).
Therefore, the composition of the present invention improves coating film toughness, water resistance,
Taking advantage of its excellent alkali resistance and adhesion to glass, it is particularly useful as a coating agent for preventing glass bottles from scattering when they are broken, and is used after repeated washing with hot alkaline water. When the emulsion of the present invention is used as a paint, it may be colored with pigments or dyes, or a silane coupling agent may be added to further improve the adhesion of the paint film. It is also possible to add additives used in the paint field, such as antifoaming agents. Blocked isocyanate (i) used in the present invention

Examples include polyurethane polyols having two or more hydroxyl groups in one molecule, which are obtained by reacting group-containing compounds.
Note that polyurethane polyol is preferred from the viewpoint of physical properties of the coating film after curing. When using a polyurethane polyol, the reaction between the polyol and the organic diisocyanate may be carried out before mixing with the blocking isocyanate and the epoxy resin.
It may be carried out at a relatively low temperature of 100°C. Furthermore, the epoxy resin used in the active hydrogen-containing compound (iii) obtained by reacting an epoxy resin and an amino compound, which is an important component in the present invention, is 2,2-bis(2,2-bis( 4-hydroxyphenyl)propane, bis(4

Examples of such amino compounds include methylamine,
ethylamine, propylamine, butylamine,
Dimethylamine, diethylamine, dipropylamine, dibutylamine, monoethanolamine,
Examples include diethanolamine and N-methylethanolamine. The reaction between the epoxy resin and the amino compound may be carried out in the absence of blocked isocyanate and/or urethane polyol, but it can also be carried out in their presence. Further, the amount of the amino compound that reacts with the epoxy resin may be an amount sufficient to open the epoxy ring of the epoxy resin or less than that. As the surfactant, common nonionic surfactants such as polyoxyethylene alkyl allyl ether, polyoxyethylene alkyl ether,
A block copolymer of propylene oxide and ethylene oxide, a compound obtained by adding polyethylene glycol to an isocyanate-terminated prepolymer obtained from polypropylene glycol and an organic diisocyanate, and the like are used. Further, anionic surfactants and cationic surfactants may be used in combination with these, but nonionic surfactants alone are particularly preferred. When carrying out emulsification, the surfactant may be added either to the mixture of blocked isocyanate and polyol (hereinafter referred to as the resin phase) or to the aqueous phase. The aqueous emulsion of the present invention is usually produced by dropping the resin phase into an aqueous phase stirred at high speed, by stirring the resin phase and aqueous phase together at high speed, or by adding water or hot water while stirring the resin phase. Add little by little
This is carried out by a so-called phase inversion emulsification method.
During such production, a solvent may be used for reasons such as adjusting the viscosity during the reaction, and if necessary, the solvent may be distilled off by heating under reduced pressure after emulsification. The aqueous emulsion of the present invention comprises the above-mentioned blocked isocyanate (i), polyether polyol and/or
or a polyester polyol (ii) and an active aqueous containing compound (iii) of an epoxy resin and an amino compound.
