Description
Technical field
The present invention relates to the sealing material use polyurethane resin formative compositions of membrane module, particularly relate to be suitable for blood
The sealing material use polyurethane resin formative compositions of the membrane module of the encapsulant of liquid processor or water purifier.
Background technology
Sealing material use polyurethane resin formative compositions as membrane module, it is known to use such as Oleum Ricini system is polynary
Alcohol and N, N, N ', the mixture of N '-four (2-hydroxypropyl) ethylenediamine (see, for example patent documentation as polyol component
1)。
In recent years, in order to improve the productivity ratio of blood processor or water purifier, it is desirable to the sealing material use of rapidly-curable
Polyurethane resin formative compositions.But, in order to obtain rapidly-curable, it is necessary to improve N, N, N ', N '-four (2-
Hydroxypropyl) content of ethylenediamine, the viscosity of mixed liquor before this exists because injection raises and pot life shortens and leads
Cause is difficult to the problems such as injection molding operation.It addition, the outward appearance expectation of sealing material use polyurethane resin formative compositions
Low and transparent for turbidity, but if N, N, N ', the content of N '-four (2-hydroxypropyl) ethylenediamine increases, then have resin
Turbidity raise and there is the trend of nebulousurine.On the other hand, in order to obtain rapidly-curable there is also use two Laurels
The method of the metal series catalysts such as acid dibutyl tin, but when for purposes such as blood processors, metal is the most molten
Go out and make safety have problems to blood.
It addition, generally in hollow fiber film assembly, the bundle of a large amount of doughnut boundlings is filled in cylindrical vessel
In, be then injected into polyurethane resin formative compositions, utilize polyurethane resin solution to carry out between doughnut simultaneously and
Joint between cylindrical vessel.After the solidification of polyurethane resin formative compositions, doughnut is connected bundles of part
Cut off in the direction vertical with the arranged direction of doughnut, use this manufacture method to manufacture hollow fiber film assembly.
But, in the case of using conventional polyurethane resin formative compositions, when the end after cutting off is observed,
The apex height of doughnut and the bottom surface of polyurethane resin existed between doughnut produce jump (concavo-convex).This
Concavo-convex big time, polluter can be attached to end or can be in jog remained blood when blood treatment, therefore phase
Hope section concavo-convex little, flatness is excellent.

Means for solving the above
The present inventor conducts in-depth research to solve the problems referred to above point, and result obtains the present invention.That is, the present invention
Relate to: the sealing material use polyurethane resin formative compositions of membrane module, described polyurethane resin formative compositions
Being made up of with the firming agent containing polyol component (B) the host containing organic multiple isocyanate composition (A), its feature exists
In, described host and/or described firming agent contain two ring types amidine salt (C) represented by formula (1)；The sealing material of membrane module
Material polyurethane resin formative compositions, it is by the host being made up of organic multiple isocyanate composition (A), by polynary
Firming agent and two ring types amidine salt (C) represented by formula (1) that alcohol composition (B) is constituted are constituted；Use the film of above-mentioned composition
The encapsulant of assembly；Use the membrane module of above-mentioned encapsulant；Use at the hollow fiber type blood of above-mentioned membrane module

＜ evaluation test method ＞
(1) viscosity before the injection of mixed liquor
Rotary viscosimeter (Brookfield viscometer) is utilized to measure the viscosity (mPa s) after mixing terminates 30 seconds.
(2) working life of mixed liquor
Mensuration mixing terminates the viscosity of rear mixed liquor and reaches the time till 10Pa s.
(3) resin hardness
After mixing terminates, it is centrifuged deaeration, the cup of polypropylene weighs mixed liquor 30 parts, 25 DEG C of ripenings
30 minutes, then take out from cup, hardness is measured.Stand in the room of homoiothermic to 25 DEG C further,
Measure the hardness [Shore D: instantaneous value { Shore D hardness meter, height after 3 hours, 24 hours and 72 hours stand
Molecule gauge Co., Ltd. system }].
(4) stannum stripping quantity
After mixing terminates, it is centrifuged deaeration, according to resin in the box of the polystyrene of about 8cm × about 11cm
Thickness reaches the mode of about 2mm and weighs mixed liquor, 40 DEG C of 1 weeks of ripening, then will solidification after resin from
The box of polystyrene takes out, and is cut into the square size of 1cm.Sanction is taken in the conical flask that volume is 100mL
Resin 10g after cutting and ethanol 50mL also seals.With agitator with the temperature oscillation 1 hour of 25 DEG C, so
After take supernatant, utilize ICP-AES (ICP-AES) method measure tin concentration.
(5) potassium permanganate consumption
After mixing terminates, it is centrifuged deaeration, according to resin in the box of the polystyrene of about 8cm × about 11cm
Thickness reaches the mode of about 2mm and weighs mixed liquor, 40 DEG C of 1 weeks of ripening, then will solidification after resin from
The box of polystyrene takes out, cuts into the square size of 1cm.The beaker of volume 200mL takes after cutting
The ion exchange water of resin 15g and 150ml, after standing 1 hour at 70 DEG C, cool down, resin will be removed
After extract be transferred in other container, as experimental liquid.Possessing the triangle that volume is 100mL of cooling tube
Flask takes experimental liquid 10mL, adds potassium permanganate solution 20mL and 10% weight percent sulfuric acid of 0.002mol/L
1.0mL, then seethes with excitement 3 minutes in the oil bath of 140 DEG C, adds potassium iodide 0.1g and carry out close after being cooled to room temperature
Envelope, carries out vibration mixing, then places 10 minutes, then carries out dripping with the hypo solution of 0.01mol/L
Fixed.As blank assay, change experimental liquid 10mL into ion exchange water 10mL, enter the most as described above
Row test.
It should be noted that potassium permanganate consumption is the most, leachable is the most.
(6) resin outward appearance and resin turbidity (mist degree)
After mixing terminates, it is centrifuged deaeration, according to resin in the box of the polystyrene of about 8cm × about 11cm
Thickness reaches the mode of about 1mm and weighs mixed liquor, after 25 DEG C of ripenings 72 hours, will solidify resin from polyphenyl second
The box of alkene takes out, uses visual observations outward appearance, be evaluated according to following evaluation criterion, use haze meter further
[BYKgardner society system (HAZE-GARDDUAL)] measures turbidity.
Evaluation criterion ＞ of ＜ outward appearance
Transparent be designated as zero, nebulousurine be designated as ×.
(7) flatness of the section in membrane module
To can two ends load onto the internal diameter of injection molding cover be 40mm, the Merlon rounding of a length of 300mm
Filling polysulfones doughnut arranged in parallel (length 320mm, external diameter 280 μm, thickness 40 μm) 10,000 in cylinder container
Root, loads onto injection molding cover at two ends.This membrane module is placed in centrifugal shaper, inject mixed liquor 60g carry out from
Heart molding.From centrifugal forming start products formed is taken out from centrifugal shaper after 20 minutes, unload two ends
Injection molding cover.The ripening of 30 minutes is carried out, then with the arranged direction of doughnut vertically to polyurethane at 25 DEG C
Doughnut is connected bundles of part by resin to cut off.After cut-out, by membrane module in the room of homoiothermic to 25 DEG C
In middle 1 week of standing, observe section with microscope [Olympus Co., Ltd's system " DSX500 ": multiplying power 100 times]
Apparent condition.
The metewand ＞ of ＜ section
By unconfirmed being designated as zero to concavo-convex and smooth situation, will confirm that concavo-convex rather than smooth situation and be designated as ×.
