Abstract
A method for producing a phenylphosphonic acid zinc salt includes a step of reacting a phenylphosphonic acid represented by Formula (1) and a zinc compound with each other in the presence of polyethylene glycol in water:
Description
The present disclosure relates to a method for producing a phenylphosphonic acid zinc salt, powder of a phenylphosphonic acid zinc salt, the use of the same as a crystal nucleating agent, and a moisture-curable hotmelt urethane resin adhesive.
Background Art
Moisture-curable hotmelt urethane resins have excellent adhesiveness and can adjust an adhesion time relatively freely, are thus suitable for adhesives for use in adhesion processing requiring continuous production and forming processing such as sealing work, and are used in a wide variety of fields. However, in wood wrapping applications for decorative sheets, in which initial strength is required, and electric/electronic parts and automotive parts applications, in which continuous production on high-speed lines is required, the problem can arise that the parts are moved to the next process with urethane resin insufficiently cooled and solidified.
To solve the above problem, metal salts of phenylphosphonic acid compounds have been added to urethane resins as crystal nucleating agents to reduce a solidification time. WO 2011/030822, for example, discloses a method for producing a phenylphosphonic acid metal salt that reacts a phenylphosphonic acid compound and a metal salt, a metal oxide, or a metal hydroxide the amount of which exceeds the equivalent of the phenylphosphonic acid compound with each other as a method for producing a phenylphosphonic acid metal salt suitable as a crystal nucleating agent.
Summary of Invention
According to study by the inventors of the present invention, there is room to further reduce the solidification time of the moisture-curable hotmelt urethane resin when the phenylphosphonic acid metal salt is used as the crystal nucleating agent.
Given these circumstances, an object of an aspect of the present invention is to provide a method for producing a phenylphosphonic acid zinc salt that can be suitably used as a crystal nucleating agent that can further reduce the solidification time of a moisture-curable hotmelt urethane resin and powder of the phenylphosphonic acid zinc salt. An object of another aspect of the present invention is to provide a moisture-curable hotmelt urethane resin adhesive with a further reduced solidification time.
The inventors of the present invention have found out that by causing polyethylene glycol to coexist when phenylphosphonic acid and a zinc compound are reacted with each other in water, a phenylphosphonic acid zinc salt and its powder that can be suitably used as a crystal nucleating agent that can further reduce the solidification time of a moisture-curable hotmelt urethane resin can be obtained.
The present invention includes the following aspects.
[1] A method for producing a phenylphosphonic acid zinc salt, the method including a step of reacting a phenylphosphonic acid represented by Formula (1) and a zinc compound with each other in the presence of polyethylene glycol in water:
[2] The method for producing a phenylphosphonic acid zinc salt according to[1] , in which an amount of the zinc compound is 1 mole or less with respect to 1 mole of the phenylphosphonic acid represented by Formula (1) .
[3] Powder of a phenylphosphonic acid zinc salt represented by Formula (2) obtained by the method for producing a phenylphosphonic acid zinc salt according to [1] or [2] .
[4] Use of the powder according to [3] as a crystal nucleating agent.
[5] A moisture-curable hotmelt urethane resin adhesive containing an isocyanate group-terminated urethane prepolymer and the powder according to [3] .
[6] The moisture-curable hotmelt urethane resin adhesive according to [5] , in which a content of the powder is 0.1 to 10%by mass based on an entire amount of the moisture-curable hotmelt urethane resin adhesive.
An aspect of the present invention can provide a method for producing a phenylphosphonic acid zinc salt that can be suitably used as a crystal nucleating agent that can further reduce the solidification time of a moisture-curable hotmelt urethane resin and powder of the phenylphosphonic acid zinc salt. Another aspect of the invention can provide a moisture-curable hotmelt urethane resin adhesive with a further reduced solidification time.
Description of Embodiments
The following describes embodiments of the present invention in detail. An embodiment of the present invention is a method for producing a phenylphosphonic acid zinc salt, the method including a step of reacting a phenylphosphonic acid represented by Formula (1) and a zinc compound with each other in the presence of polyethylene glycol in water (a reaction step) :
In the reaction step, by adding an aqueous solution in which a zinc compound dissolved in water and a solution in which polyethylene glycol is dissolved in a solvent to an aqueous solution in which the phenylphosphonic acid represented by Formula (1) is dissolved in water, the phenylphosphonic acid represented by Formula (1) is reacted with the zinc compound, for example. In this process, the above reaction can be made to proceed by gradually adding an aqueous alkaline solution such as an aqueous sodium hydroxide solution, for example.
The amount of water in the aqueous solution of the phenylphosphonic acid represented by Formula (1) may be 1,000 parts by mass or more, 2,000 parts by mass or more, or 3,000 parts by mass or more and 10,000 parts by mass or less, 7,000 parts by mass or less, or 5,000 parts by mass or less with respect to 100 parts by mass of the phenylphosphonic acid represented by Formula (1) .
The zinc compound may be zinc halide, zinc oxide, or zinc acetate, for example. The zinc halide may be zinc fluoride, zinc chloride, zinc bromide, or zinc iodide.
The amount of water in the aqueous solution of the zinc compound may be 500 parts by mass or more, 1,000 parts by mass or more, or 2,000 parts by mass or more and 5,000 parts by mass or less, 4,000 parts by mass or less, or 3,000 parts by mass or less with respect to 100 parts by mass of the zinc compound.
The amount of the zinc compound may be 0.8 mole or more, 0.9 mole or more, or 0.95 mole or more and 1.1 mole or less, 1.05 mole or less, or 1 mole or less with respect to 1 mole of the phenylphosphonic acid represented by Formula (1) .
The number average molecular weight (Mn) of polyethylene glycol may be 200 or more, 500 or more, or 800 or more and 2,000 or less, 1,500 or less, or 1,200 or less.
The solvent dissolving polyethylene glycol may be an alcohol. The alcohol may be an aliphatic alcohol. Examples of the alcohol include methanol, ethanol, 1-propanol, 2-propanol, and ethylene glycol.
The amount of the solvent in the polyethylene glycol solution may be 100 parts by mass or more, 150 parts by mass or more, or 200 parts by mass or more and 400 parts by mass or less, 350 parts by mass or less, or 300 parts by mass or less with respect to 100 parts by mass of polyethylene glycol.
A white precipitate precipitated by the reaction step is filtered out, is washed with water, and is then dried to obtain a phenylphosphonic acid zinc salt represented by Formula (2) as powder (white powder) . That is, another embodiment of the present invention is powder of the phenylphosphonic acid zinc salt represented by Formula (2) obtained by the method of production:
This powder of the phenylphosphonic acid zinc salt represented by Formula (2) is obtained by the method of production and can thereby further reduce the solidification time of a moisture-curable hotmelt urethane resin compared to commercially available powder of a phenylphosphonic acid zinc salt, for example. Although it is unclear what kinds of structure or characteristics of the powder of the phenylphosphonic acid zinc salt represented by Formula (2) contribute to such an effect, the inventors of the present invention assume the reason why the above effect is produced as follows.
Polyethylene glycol can function as a dispersion medium in the reaction step, whereby when crystals of the phenylphosphonic acid zinc salt represented by Formula (2) are formed, the dispersibility of the crystals in water becomes favorable, and crystals (powder) with less flocculation can be obtained. Thus, it is thought that when this powder as a crystal nucleating agent is mixed with the urethane resin, the contact area between the crystal nucleating agent and the urethane resin is larger, and thus crystallization of the urethane resin is promoted.
In an embodiment, the powder of the phenylphosphonic acid zinc salt represented by Formula (2) is obtained by the method of production and can thereby also achieve a reduction in the tack-free time of a moisture-curable hotmelt urethane resin adhesive, improvement in initial creep properties, and improvement in initial peeling strength compared to commercially available powder of a phenylphosphonic acid zinc salt, for example.
As described above, the powder of the phenylphosphonic acid zinc salt represented by Formula (2) can be suitably used as a crystal nucleating agent, and more specifically, as a crystal nucleating agent promoting crystallization of urethane resins. That is, another embodiment of the present invention is the use (application) of the powder of the phenylphosphonic acid zinc salt represented by Formula (2) .
Another embodiment of the present invention is a moisture-curable hotmelt urethane resin adhesive containing an isocyanate group-terminated urethane prepolymer and the powder of the phenylphosphonic acid zinc salt represented by Formula (2) above.
The isocyanate group-terminated urethane prepolymer can be obtained by reacting a polyol (A) and a polyisocyanate (B) with each other in the presence of the phenylphosphonic acid zinc salt represented by Formula (2) above and the zinc phosphate complex represented by Formula (4) above.
The polyol (A) may contain an aliphatic polyester polyol, contain two kinds of aliphatic polyester polyols (an aliphatic polyester polyol (a1) and an aromatic polyester polyol (a2) described below) , or contain the two kinds of aliphatic polyester polyols (the aliphatic polyester polyol (a1) and the aromatic polyester polyol (a2) described below) and another polyol (a3) other than the aliphatic polyester polyols.
The aliphatic polyester polyol (a1) is a polyester polyol produced by a known and customary method with an aliphatic polycarboxylic acid and an aliphatic polyol as main components, and the method for producing the same is not limited to a particular method.
Preferred examples of the aliphatic polycarboxylic acid used in the synthesis of the aliphatic polyester polyol (a1) include C
4-12 aliphatic polycarboxylic acids such as succinic acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, decanedioic acid, dodecanedioic acid, eicosanedioic acid, citraconic acid, itaconic acid, citraconic anhydride, and itaconic anhydride.
For the aliphatic polycarboxylic acid, lower alkyl ester derivatives such as methyl esters, acid anhydrides, and corresponding acid derivatives such as acid halides may be used, for example.
The aliphatic polyol used in the synthesis of the aliphatic polyester polyol (a1) is one having at least two hydroxy groups in the molecule and is preferably a C
2-12 aliphatic polyol. The (a1) may be linear, branched, or cyclic in structure.
Examples of the aliphatic polyol include linear aliphatic polyols such as ethylene glycol, 1, 3-propanediol, 1, 4-butanediol, 1, 5-pentanediol, 1, 6-hexanediol, 1, 7-heptanediol, 1, 8-octanediol, 1, 9-nonanediol, 1, 10-decanediol 1, 12-dodecanediol, diethylene glycol, triethylene glycol, triethylene glycol, and tetraethylene glycol; branched aliphatic polyols such as neopentyl glycol, 1, 3-butanediol, 2, 2-diethyl-1, 3-propanediol, 2, 2-diethylpropanediol, 3-methyl-1, 5-pentanediol, 2-ethyl-2-butyl-1, 3-propanediol, 2-methyl-1, 8-octanediol, 2, 4-diethyl-1, 5-pentanediol, trimethylol ethane, trimethylol propane, and pentaerythritol; and alicyclic polyols such as cyclopentanediol, cyclohexanediol, and cyclohexanedimethanol. Among these, ethylene glycol, 1, 6-hexanediol, and neopentyl glycol are preferred.
Adducts with various alkylene oxides added to hydrogenated bisphenol A, hydrogenated bisphenol F, or the like can also be used. Polymerized products with γ-butyrolactone, ε-caprolactone, or the like subjected to ring-opening polymerization using a low molecular weight polyol as an initiator can also be used. They may be used alone or used in combination of two or more.
Among the combinations of the aliphatic polycarboxylic acid and the aliphatic polyol, the aliphatic polyester polyol (a1) produced by a combination of a C
4-12 aliphatic polycarboxylic acid and a C
2-12 aliphatic polyol is contained in the polyol (A) , whereby the viscosity stability of the hotmelt urethane resin adhesive during forming processing is further improved, and an excellent effect of preventing a reduction in melt viscosity can be produced, which is preferred.
The aromatic polyester polyol (a2) is a polyester polyol produced by a known and customary method with an aromatic polycarboxylic acid and an aliphatic polyol or an aliphatic polycarboxylic acid and an aromatic polyol as main components, and the method for producing the same is not limited to a particular method.
The aromatic polycarboxylic acid is a carboxylic acid in which at least two carboxy groups are bonded to an aromatic ring and is preferably a C8-24 aromatic polycarboxylic acid. Examples thereof include orthophthalic acid, isophthalic acid, terephthalic acid, trimellitic acid, pyromellitic acid, biphenyldicarboxylic acid, and naphthalene dicarboxylic acid. They may be used alone or used in combination of two or more.
For the aromatic polycarboxylic acid, lower alkyl ester derivatives such as methyl esters, acid anhydrides, and corresponding acid derivatives such as acid halides may be used, for example.
Examples of the aliphatic polyol include the same as the aliphatic polyol that can be used in the synthesis of the aliphatic polyester polyol (a1) .
The aliphatic polyol that can be used in the synthesis of the aromatic polyester polyol (a2) and the aliphatic polyester polyol (a1) may be diethylene glycol, triethylene glycol, tetraethylene glycol, 1, 4-bis (β-hydroxyethoxy) benzene, or the like, in which part of its carbon atoms is replaced by oxygen atoms or aromatic rings. These aliphatic polyols may also be used alone or used in combination of two or more.
Furthermore, mixtures of polyester polyols obtained from the aromatic polycarboxylic acid and the aliphatic polyol may also be used.
Examples of the aliphatic polycarboxylic acid that can be used in the synthesis of the aromatic polyester polyol (a2) include C
4-12 aliphatic polycarboxylic acids, which are the same as those for the aliphatic polycarboxylic acid that can be used in the synthesis of the aliphatic polyester polyol (a1) .
The aromatic polyol is not limited to a particular aromatic polyol. Examples thereof include aromatic polyols obtained from aliphatic polyols such as ethylene glycol and neopentyl glycol and aromatic polycarboxylic acids such as orthophthalic acid and terephthalic acid.
As the aromatic polyol, adducts with alkylene oxides such as ethylene oxide, propylene oxide, and butylene oxide added to bisphenol A, bisphenol F, or the like can also be used, for example.
The equivalent ratio of hydroxy groups possessed by the aliphatic polyol and the aromatic polyol to carboxy groups of the aliphatic polycarboxylic acid and the aromatic polycarboxylic acid during the synthesis of the aliphatic polyester polyol (a1) and the aromatic polyester polyol (a2) (that is, an [OH/COOH equivalent ratio] ) is preferably in a range of 1.03 to 1.50 and more preferably in a range of 1.05 to 1.30. When the [OH/COOH equivalent ratio] is in such a range, the hydroxy group-terminated polyols can be generated in a larger amount, and a urethanation reaction with the polyisocyanate (B) can be made to proceed more easily, which is preferred.
The polycondensation conditions during the synthesis of the aliphatic polyester polyol (a1) and the aromatic polyester polyol (a2) are not limited to particular conditions so long as no abnormal reaction is caused and normal products can be obtained. Normally, certain amounts of the aliphatic polycarboxylic acid and the aliphatic polyol or the aromatic polycarboxylic acid and the aliphatic polyol may be subjected to an esterification reaction or an ester exchange reaction at an internal temperature of 150 to 250℃ for 5 to 50 hours in the presence or in the absence of a catalyst and then be subjected to a polycondensation reaction.
The polycondensation reaction is preferably performed in the presence of a catalyst because the reaction easily proceeds. The catalyst is not limited to a particular catalyst. Examples thereof include titanium-based catalysts such as titanium tetrabutoxide and tin-based catalysts such as dibutyltin oxide.
The catalyst may be charged together with the aliphatic polyol and the aliphatic polycarboxylic acid or the aliphatic polyol and the aromatic polycarboxylic acid or added after prepolymerization in the absence of a catalyst.
In the production of the aliphatic polyester polyol (a1) and the aromatic polyester polyol (a2) , it is desirable to make almost all both ends hydroxy groups and to leave as few carboxy group ends as possible, and for this purpose it is effective and preferred to add the catalyst after performing the prepolymerization.
The number average molecular weight (hereinafter, referred to as "Mn" ) of the aliphatic polyester polyol (a1) and the aromatic polyester polyol (a2) is preferably in a range of 500 to 6,000, more preferably in a range of 1,000 to 5,000, and particularly preferably in a range of 2,000 to 4,000. When the Mn of (a1) and (a2) is in such a range, a balance of properties such as strength and elongation according to applications can be obtained, which is preferred.
Examples of the other polyol (a3) include polycarbonate polyols, polylactone polyols, and polyether polyols. Examples of the polycarbonate polyols include polycarbonate polyols obtained using the linear aliphatic polyols such as 1, 4-butanediol, 1, 5-pentanediol, and 1, 6-hexanediol. Examples of the polylactone polyols include polycaprolactone polyols obtained by ring-opening polymerization of caprolactone monomers.

When the content ratio is in such a range, the melt viscosity of the polyol (A) can be adjusted to an appropriate range, and a moisture-curable hotmelt urethane resin adhesive exhibiting excellent workability and miscibility and having further excellent solidification properties can be obtained.
Examples of the polyisocyanate (B) include known and customary aliphatic, aromatic, and alicyclic polyisocyanates. Examples thereof include aromatic diisocyanates such as diphenylmethane diisocyanate (MDI; a 4, 4′ form, a 2, 4′ form, a 2, 2′ form, mixtures thereof, and crude MDI) , carbodiimide-modified MDI (modified MDI) , polymethylene polyphenyl polyisocyanate, carbodiimidated diphenylmethane polyisocyanate, xylene diisocyanate, tolylene diisocyanate (TDI; a 2, 4 form, a 2, 6 form, and mixtures thereof) , xylylene diisocyanate (XDI) , 1, 5-naphthalene diisocyanate (NDI) , tetramethyl xylene diisocyanate, and phenylene diisocyanate; aliphatic diisocyanates such as hexamethylene diisocyanate (HDI) , dimer acid diisocyanate, norbornene diisocyanate, lysine diisocyanate, and tetramethylxylylene diisocyanate; and alicyclic diisocyanates such as isophorone diisocyanate (IPDI) , hydrogenated diphenylmethane diisocyanate (hydrogenated MDI) , hydrogenated xylylene diisocyanate (hydrogenated XDI) , cyclohexane diisocyanate, dicyclohexylmethane diisocyanate, and isophorone diisocyanate. Among these, MDI and XDI are preferred because of their fast reaction with the polyol (A) and moisture (water) to give excellent workability. They may be used alone or used in combination of two or more.
The ratio between the polyol (A) and the polyisocyanate (B) used when the isocyanate group-terminated urethane prepolymer (hereinafter, referred to as a "prepolymer" ) is synthesized may be in a range that does not adversely affect reaction behavior, product quality, and the like. Normally, the equivalent ratio of isocyanate groups possessed by the polyisocyanate (B) to hydroxy groups possessed by the polyol (A) (hereinafter, referred to as an [NCO/OH equivalent ratio] ) is preferably in a range of 1.2 to 4.0 and more preferably in a range of 1.5 to 3.0. When the [NCO/OH equivalent ratio] is in such a range, the melt viscosity of the objective moisture-curable hotmelt urethane resin composition is in an appropriate range and performance such as excellent workability, film properties, and further excellent solidification properties can be exhibited.
The reaction conditions may be set in a range that does not adversely affect reaction behavior, product quality, and the like and are not limited to particular conditions. Normally, the reaction is preferably conducted at a reaction temperature of 80 to 130℃ for 1 to 10 hours.
For the reaction method, a known reaction method such as batch reaction, semi-continuous reaction, or continuous reaction can be selected, for example.
The reaction can be performed in a solvent or solvent-free. However, when the reaction is performed in a solvent, it is preferable to remove the solvent during the reaction or after the end of the reaction to finally eliminate the solvent. The method of removing the solvent is not limited to a particular method.
