Next, a method for producing the water-based polyurethane resin will be described.

The specific method for producing the above-mentioned isocyanate group-terminated prepolymer is not particularly limited, and for example, it can be produced by a conventionally known one-stage so-called one-shot method, a multi-stage isocyanate polyaddition reaction method, or the like. The reaction temperature at this time is preferably 40 to 150°C. Also, an organic solvent that does not react with isocyanate groups may be added during or after the reaction. As such an organic solvent, for example, acetone, methyl ethyl ketone, toluene, tetrahydrofuran, etc. can be used. During the reaction, if necessary, dibutyltin dilaurate, stannous octoate, dibutyltin di-2-ethylhexoate, triethylamine, triethylenediamine, N-methylmorpholine, bismath tris (2-ethylhexanoate) or a reaction inhibitor such as phosphoric acid, sodium hydrogen phosphate, p-toluenesulfonic acid, adipic acid and benzoyl chloride.

The content of residual isocyanate groups in the isocyanate group-terminated prepolymer is preferably 0.2 to 4.5% by mass. Within this range, the film formability of the water-based polyurethane resin composition obtained by subsequent chain extension with polyamine is good, and the formed film is soft and exhibits appropriate flexibility. Incidentally, the residual isocyanate group content can be obtained by the following method.

0.3 g of the resulting urethane prepolymer is placed in an Erlenmeyer flask, mixed with 10 ml of 0.1N dibutylamine toluene solution, and dissolved. Then, several drops of bromophenol blue solution are added, titration is performed with a 0.1N hydrochloric acid methanol solution, and the free isocyanate group content NCO% can be determined by the following formula.
NCO % = (ab) x 0.42 x f/x
a: Titration amount of 0.1N hydrochloric acid methanol solution when only 10 ml of 0.1N dibutylamine toluene solution was titrated b: Titration amount of 0.1N hydrochloric acid methanol solution when titrating the composition during reaction f: 0. Factor x of 1N hydrochloric acid methanol solution: Amount of sampling.

In order to keep the content of residual isocyanate groups within the above range, it is preferable to adjust the molar ratio of isocyanate groups/hydroxyl groups in the starting material to 100/80 to 100/60 during prepolymer production. By adjusting the isocyanate group/hydroxyl group molar ratio within this range, the isocyanate group-terminated prepolymer has an appropriate viscosity and is easily emulsified. In addition, the texture of the structure treated with the antibacterial/antiviral agent composition can be made softer, and whitening during bending can be more easily prevented.

Neutralization of the anionic groups of the isocyanate group-terminated prepolymer can be carried out using a suitable known method before, during or after the preparation of the isocyanate group-terminated prepolymer. There are no particular restrictions on the compound used for neutralizing the isocyanate group-terminated prepolymer having such an anionic group. Examples include trimethylamine, triethylamine, tri-n-propylamine, tributylamine, N-methyl-diethanolamine, Examples include amines such as N-dimethylmonoethanolamine, N,N-diethylmonoethanolamine and triethanolamine, potassium hydroxide, sodium hydroxide and ammonia. Among them, tertiary amines such as trimethylamine, triethylamine, tri-n-propylamine and tributylamine are particularly preferred.

There are no particular restrictions on the emulsifying and dispersing equipment used when emulsifying and dispersing the neutralized isocyanate group-terminated prepolymer in water, and examples include homomixers, homogenizers, and dispersers. Further, when emulsifying and dispersing the neutralized isocyanate group-terminated prepolymer in water, the neutralized isocyanate group-terminated prepolymer is emulsified and dispersed in water in a temperature range of 0 to 40 ° C., and the isocyanate group and It is preferable to suppress the reaction with water as much as possible. Furthermore, when emulsifying and dispersing in this manner, reaction inhibitors such as phosphoric acid, sodium dihydrogen phosphate, disodium hydrogen phosphate, paratoluenesulfonic acid, adipic acid, and benzoyl chloride can be added as necessary. .

The isocyanate group-terminated prepolymer emulsified and dispersed in water uses a polyamine compound containing two or more amino groups per molecule of at least one selected from the group consisting of primary amino groups and secondary amino groups. May be chain extended. The reaction between the isocyanate group-terminated prepolymer and the polyamine compound is completed at a reaction temperature of 20 to 50° C. usually in 30 to 120 minutes.

When the above-mentioned organic solvent is used when producing the isocyanate group-terminated prepolymer, it is desirable to distill off the organic solvent at 30 to 80°C under reduced pressure, for example, after the chain extension reaction or emulsification and dispersion. An emulsified dispersion of a water-based polyurethane resin can be obtained by such a preparation method. The resin solid content (non-volatile content) concentration in the emulsified dispersion of the water-based polyurethane resin may be, for example, 20% or more and 60% or less. The resin solid content concentration can also be adjusted by adding or distilling off water.

Specifically, (1) a method of reacting a polyol, a polyisocyanate and a chain extender together (one-step method), and (2) first, a polyol and a polyisocyanate are reacted to obtain a prepolymer having isocyanate groups at both ends. and then reacting this prepolymer with a chain extender (two-step method). This two-step method includes a step of reacting a polyol with one or more equivalents of polyisocyanate in advance to prepare an intermediate (prepolymer) in which both ends corresponding to the soft segments of the urethane resin are blocked with isocyanate groups. It is a way to go through. By preparing a prepolymer in advance and then reacting it with a chain extender, it is easy to adjust the molecular weight of the soft segment part, and the phase separation between the soft segment and the hard segment is easily achieved, and it is easy to demonstrate the performance as a urethane resin. Characteristic. In particular, when the chain extender is a diamine, the reaction rate with the isocyanate group is significantly different from that with the hydroxyl group of the polyol, so it is more preferable to carry out polyurethane urea formation by a two-step method (prepolymer method). .

(single stage method)
The one-step method, which is also called a one-shot method, is a method in which a polyol, a polyisocyanate and a chain extender are charged together to carry out the reaction. The reaction temperature in the one-step process is usually 0 to 250° C., but can be appropriately set depending on the amount of solvent, reactivity of raw materials used, reaction equipment and the like. If the reaction temperature is too low, the reaction progresses too slowly and the solubility of the raw materials and polymer tends to decrease, resulting in a decrease in productivity. It may happen. Also, the reaction may be carried out while defoaming under reduced pressure. Furthermore, catalysts, stabilizers and the like may be added as necessary. Examples of catalysts include triethylamine, tributylamine, dibutyltin dilaurate, stannous octoate, acetic acid, phosphoric acid, sulfuric acid, hydrochloric acid, sulfonic acid, etc. Stabilizers include, for example, 2,6-dibutyl -4-methylphenol, distearylthiodipropionate, diβ-naphthylphenylenediamine, tri(dinonylphenyl)phosphite and the like.

(two-step method)
The two-stage method is also called a prepolymer method, in which a prepolymer is produced by reacting a polyisocyanate and a polyol in advance, usually at a reaction equivalent ratio of 1.0 to 10.00, and then polyisocyanate or polyol is added thereto. It is a method of reacting in two stages by adding a compound having active hydrogen such as a hydric alcohol or an amine. In particular, a method of preparing a prepolymer containing isocyanate groups at both ends by reacting a polyisocyanate in an equivalent amount or more with a polyol, and then reacting the prepolymer with a chain extender such as a short-chain diol or diamine to obtain a urethane resin. is useful.

In the case of production by a two-step method, (1) a prepolymer may be synthesized by directly reacting a polyisocyanate and a polyol without using a solvent, and a chain extender may act as it is, or (2) the above ( A prepolymer may be synthesized by the method of 1), then the prepolymer may be dissolved in a solvent and then treated with a chain extender, or (3) a polyisocyanate and a polyol may be reacted in a solvent to produce a prepolymer. may be synthesized and directly reacted with a chain extender in a solvent. In the method (2), the chain extender may be dissolved in the solvent and then acted on the prepolymer, or the chain extender may be dissolved at the same time as the prepolymer is dissolved in the solvent. .

The reaction temperature in the two-step method is usually 0 to 250°C, but can be appropriately set depending on the amount of solvent, the reactivity of the raw materials used, the reaction equipment, and the like. If the reaction temperature is too low, the reaction progresses too slowly and the solubility of the raw materials and polymer tends to decrease, resulting in a decrease in productivity. It may happen. Also, the reaction may be carried out while defoaming under reduced pressure. Furthermore, catalysts, stabilizers and the like may be added as necessary. Examples of catalysts include triethylamine, tributylamine, dibutyltin dilaurate, stannous octoate, acetic acid, phosphoric acid, sulfuric acid, hydrochloric acid, sulfonic acid, etc. Stabilizers include, for example, 2,6-dibutyl -4-methylphenol, distearylthiodipropionate, diβ-naphthylphenylenediamine, tri(dinonylphenyl)phosphite and the like. When the chain extender is highly reactive such as a short-chain aliphatic amine, it is preferable to carry out the reaction without adding a catalyst.

In such urethane resin production methods (one-step method and two-step method), a solvent can be used for the purpose of adjusting the viscosity. Solvents may be used alone or in combination of two or more, and any known solvent can be used. Examples of such solvents include aliphatic hydrocarbon solvents such as hexane, cyclohexane, methylcyclohexane, ethylcyclohexane, heptane, nonane, octane, isooctane, and decane; aromatic hydrocarbon solvents such as benzene, toluene, xylene, cumene, and ethylbenzene; hydrogen; ester solvents such as ethyl acetate and butyl acetate; ether solvents such as diethyl ether, diisopropyl ether and methyl-tert-butyl ether; ketone solvents such as cyclohexanone, methyl ethyl ketone, dimethyl ketone, diethyl ketone, diisopropyl ketone and methyl isobutyl ketone Solvents may be mentioned.

The amount of all isocyanate groups in the polyurethane (meth)acrylate oligomer and the amount of all functional groups that react with isocyanate groups such as hydroxyl groups and amino groups are usually theoretically equimolar and expressed in mol%.

That is, the amounts of the polyisocyanate, polyol, hydroxyalkyl (meth)acrylate, and other raw material compounds used in the polyurethane (meth)acrylate-based oligomer are determined by the total amount of isocyanate groups in the polyurethane (meth)acrylate-based oligomer and the reaction therewith. The amount of all the functional groups is an equimolar amount, or an amount that is 50 mol % or more and 200 mol % or less in terms of mol % of the functional groups to the isocyanate group.
