Description

The exothermic compositions of ink-like or cream pasty state, the radiator body that uses this exothermic compositions and manufacture method thereof

The present invention relates to the exothermic compositions of a kind of ink-like or cream pasty state and use the radiator body of this exothermic compositions, and the manufacture method of this radiator body.This method is that exothermic compositions is formed ink-like or cream pasty state, is transferred at a high speed on the packaging material by the exothermic compositions with this ink-like or cream pasty state, produces extra-thin radiator body, and exothermic compositions is distributed in the bag with homogeneous thickness; In addition, can or all be fixed in the bag one one of exothermic compositions, thereby can prevent moving of it, be as thin as a wafer a kind of and soft, and usability is the radiator body of excellence very.

In recent years, as the disposable hand warmer of what is called, be extensive use of the intravital radiator body of flat bag of exothermic compositions inclosure by the film like or the laminar coating material formation of air permeability or bubble-tight film like or laminar base material and air permeability.

In addition, the somebody proposes to utilize the one side at this bag to form binder layer, makes it can directly be attached to the radiator body of underwear or human body surface; Further, this binder layer can also contain or be loaded with wet-cloth agent, utilizes warm and humid cloth, it is contained or is loaded with the Percutaneously absorbable medicine, and promptly the transdermic absorbent as medicine uses (consult the spy and open flat 2-149272 communique).

Manufacture method as this radiator body, after generally all adopting in the regulation zone of exothermic compositions being cast base material, again by coated with the coating material that air permeability is arranged, after this, further use heat seal, heat fusing is a tackiness agent etc., the method that the circumference of base material and coating material was sealed up along its full week.

Produced like this radiator body for restraining its thermopositive reaction before in use, all is that it is sealed in the bubble-tight outer bag, so that preserve or circulation.

Exothermic compositions as the past, what use is except necessary metal powder of thermopositive reaction and moisture, also cooperate with charcoal composition in order to the carbon that promotes heat release and gac etc., and for destroying the oxide film on metal powder surface, make the Powdered thing of water-holding agents such as its metal chloride that recurs thermopositive reaction and wood powder.

As the method for casting this Powdered exothermic compositions, base material is moved off and on, when stopping, base material casts the method for Powdered exothermic compositions, with base material is moved with certain speed, the mouth of casting of casting Powdered exothermic compositions is moved with the speed identical with base material, Powdered exothermic compositions cast the method on the base material when moving, for the high speed of realizing making, yes, and a kind of method in back is more superior.

As before, exothermic compositions forms when Powdered, this Powdered exothermic compositions should fit in easy generation thermopositive reaction, the optimum regime of oxidizing reaction just, and this Powdered should be porous matter, it is big, so just not only extremely good with contacting of air that surface area is wanted, and can also accomplish in a single day to contact with air oxidizing reaction just takes place immediately.

Therefore, during with suitable proportioning preparation exothermic compositions, and making exothermic compositions, it is cast on the base material, with the coating material lining, and during this section till the manufacturing radiator body, the oxidizing reaction with air can take place just, thermopositive reaction just, thus the loss that the thermopositive reaction because of exothermic compositions causes produced.Cause the exothermic compositions downgrade, also have all disadvantages such as the resultant that generates by thermopositive reaction solidifies.Specifically, can cause causing the decline of product percent of pass, handle the difficulty of operation, the loaded down with trivial details property of manufacturing installation maintenance because of removing coagulum, to working hour of manufacturing installation or to the restriction of activity duration of operating personnel, the disadvantages such as difficulty that coagulum is handled.

In addition, if exothermic compositions is Powdered, just can be as mentioned above, make radiator body, the radiator body that obtains is sealed in the bubble-tight outer bag during this section, take place and the oxidizing reaction of air, and make the downgrade of radiator body, make the critical defect of its reliability reduction etc.

In order to prevent the oxidizing reaction of such exothermic compositions, should make mixing device is resistance to air loss, and to use nitrogen replacement after the air in the mixing device, just make the composition uniform mixing of exothermic compositions, but so, not only there is mixing device both complicated and expensive in addition, the problem that also has exothermic compositions and radiator body also to become expensive.

Then, when making radiator body,, when base material stops, just casting in the method for exothermic compositions, the starting of repeating group bottom material continually, stop, so the too slow problem of manufacturing speed has just been arranged in that base material is moved off and on.

On the other hand, when base material is moved with certain speed, the dog-house of casting exothermic compositions is moved on one side with the speed identical with base material, on one side exothermic compositions is cast in the method on the base material, almost completely without the stopping, starting of repeating group bottom material, so can improve manufacturing speed.

But, in this case, want to make the dog-house of casting exothermic compositions to move with the speed identical with base material, complicated apparatus must be arranged, and exothermic compositions can have wettability because of the interpolation of moisture, reprocess it for Powdered, lack flowability, the speed that this device is moved causes very big qualification, when perhaps exothermic compositions lacks filling, the fill-up of exothermic compositions just can produce deviation, and exothermic compositions is setovered in packaging material, thereby just has problems such as poor reliability.

In addition, exothermic compositions can have wettability because of moisture, but the proportioning of moisture is the degree that is lower than suitable thermopositive reaction, and this Powdered flowability that lacks in addition, only by it is cast, in distress significantly so that it is distributed in the interior problem of stated limit on the base material equably.

Therefore, when being sealed, have only by roller etc. to make exothermic compositions reach to a certain degree homogenizing coated with coating material; But, use this method, feeding source side at the bag material makes progress, the tendency that the distribution biasing of exothermic compositions is arranged, and on the feeding target direction of bag material, the abundance of exothermic compositions can increase to some extent, thereby makes the radiator body thickening, so in use must be with hand moving, to eliminate the biasing of abundance.

Therefore, whole radiator body several mm thick that will become, the sense of touch very hard ground that also becomes, not only feel is bad, and flexibility also reduces, and is difficult to be fit to for the curved surface concavo-convex or that curvature is little of the complexity of body surface; In addition, extensibility or retractility reduce, and the tracing ability of the body surface that is out of shape following body movement, moves is also poor, and the problem that produces stiff and sense of discomfort is just arranged.

Particularly, for radiator body is put into footwear and heating, must realize the thin-walled property of radiator body, blocked up radiator body is certainly existing very big inconvenience.

Particularly, the disposable body warmer in past, because exothermic compositions is a powder filling, because exothermic compositions is inner mobile at radiator body, thereby thickness can not keep necessarily being fixed in when using on the health, and it is certain that the distribution of exothermic temperature can not keep, so when being fixed in the use of same place, just constitute the reason of scalding.

In recent years, begin to popularize and utilize the decompression of porous film when heat release, prevent the product of exothermic compositions biasing, still, its present situation but is in manufacturing process, haulage stage, operational phase, can not prevent biasing fully.

In addition, before use, under the state in outer bag (storage bag) of harvesting and storing, radiator body inside is not in decompression state, so in the haulage stage, exothermic compositions still can move in radiator body; In addition, for keeping security, the homogeneity that keeps thickness, it is certain that temperature distribution when making heat release keeps, and be vital condition, but present situation is, the product of exothermic compositions biasing, will be as substandard product, returned goods or answer human consumer's requirement to give exchange in the circulation stage, this result just makes and guarantees that in the haulage stage thickness of exothermic compositions evenly becomes very important.

So, open in the clear 62-347 communique the spy, method with the adhesive exothermic compositions has been proposed, but, in the manufacturing of reality, the inboard that will be adhered to the radiator body bag to the exothermic compositions of powder is almost impossible, even if can glue, its bond strength also very a little less than, can not be completely fixed, in use can produce and peel off, become the flap that lacks flexibility, usability is variation greatly, add with tackiness agent and mix, make the variation that contacts of exothermic compositions and air, the result just becomes the reason of non-uniform temperature and temperature deviation, lacks practicality.

Therefore, the present inventor is in order to solve above-mentioned technical task, carried out deep research, develop a kind of thermopositive reaction that can suppress exothermic compositions, the loss of the exothermic compositions that the thermopositive reaction when preventing because of manufacturing causes, prevent the downgrade of exothermic compositions and all disadvantages of following solidifying of exothermic compositions to be taken place, can make the radiator body of ultra-thin shape at high speed, and, can be by exothermic compositions at the intravital uniform distribution of bag and fixing, prevent moving of this exothermic compositions, biasing, the radiator body of doing one's utmost to avoid the thermopositive reaction of exothermic compositions surplus.

Its result finds the heat release principle of disposable body warmer etc. finally, is the heat release when utilizing the metal powder oxidation, and this oxidizing reaction, thermopositive reaction just, the amount of moisture has great influence to speed of response.

That is to say, in order to promote this oxidizing reaction, excess moisture and very few, the capital is significantly slowed down reaction, it is of paramount importance that suitable moisture is arranged, and the state of this suitable moisture is arranged, the balance that just can obtain moisture and the air (oxygen) of metal powder is supplied with, make oxidizing reaction, the speed of thermopositive reaction just is maximum.

During hypohydration, air is enough, but reacts necessary water deficient, and on the other hand, during excess moisture, this moisture will become barrier layer, reduce the air feed rate to metal powder, reacts also just slow certainly.

So, the present inventor has obtained following understanding, that is: with the exothermic compositions thicknessization, be ink-like or cream pasty state, can extremely easily be undertaken stacked like this by screen printing or coating, and can produce extra-thin radiator body at high speed, thereby exothermic compositions is distributed in bag material equably; If it is the heating composition of ink-like or cream pasty state is stacked in slim paper of family expenses such as foamed thin sheet, thin slice, cotton paper and towel papers, even ground paper (hereinafter to be referred as stationery), non-woven fabrics such as corrugated plate paper or corrugated plate core disc paper, weave cotton cloth or porous film, thin slice on the time, this ink-like or cream pasty state exothermic compositions, invasive and grappling are very high, can infiltrate within the pore of these films or thin slice, thereby stop it to move, setover.

The present inventor also finds, in this case, when particularly these films or thin slice have water-absorbent, the exothermic compositions of ink-like or cream pasty state is laminated on this film or the thin slice; Perhaps on above-mentioned film or thin slice, further form water accepting layer, when being laminated in ink-like or cream pasty state exothermic compositions on the water accepting layer again, this exothermic compositions whole or one one so, just can be more prone to be fixed in this foamed thin sheet, thin slice, stationery, non-woven fabrics, weave cotton cloth or porous film, thin slice on or on the water accepting layer that forms on them, this result can prevent the moving of exothermic compositions, biasing more effectively.

In addition, the present inventor has also obtained such understanding, that is: when exothermic compositions forms ink-like or cream pasty state, compare with pulverous exothermic compositions, it is little many that surface-area is obviously wanted, and is very restricted with contacting of air, thereby also just can suppresses reaction with air significantly.

In addition, the present inventor has also obtained such understanding, that is: in the exothermic compositions of ink-like or cream pasty state, superfluous water, or free-water and/or contain the gel of moisture, can wrap metal powder, play a part air block layer, from this point, they also are very stable in air.

In this case, if in exothermic compositions, cooperate, just fit in to excess moisture the exothermic compositions of ink-like or cream pasty state, just can find the function of this superfluous water as barrier layer with excessive moisture; Like this, just can further suppress the thermopositive reaction (oxidizing reaction) with air, further improve its stability greatly.

On the other hand, the exothermic compositions of ink-like or cream pasty state, unnecessary the cooperation with excessive moisture, resemble the exothermic compositions of cream pasty state, moisture is fewer also passable, in this case, and free-water and/or contain the gel (aqueous gel) of moisture, with the function of coated metal powder performance, make it in air, can keep stable as air block layer (barrier layer).

So, exothermic compositions as ink-like, cooperation is during with excessive moisture, these superfluous waters, can by base material, coating material or be attached to ink-like or the one side of the exothermic compositions of cream pasty state or the water-absorbing material on the two sides etc. among at least a the absorption; In addition, in the exothermic compositions of cream pasty state, portion of water in free-water and/or the aqueous gel, also can by base material, coating material or be attached to ink-like or the one or both sides of cream pasty state exothermic compositions on water-absorbing material etc. among at least a the absorption, barrier layer is just lost like this, exothermic compositions becomes porous matter, and is good with contacting of air, and thermopositive reaction is successfully carried out.

Therefore during the preparation exothermic compositions, and when making the exothermic compositions of ink-like or cream pasty state, after being laminated in it on base material with means such as printing or coatings, make during this section of radiator body to being covered in coating material, oxidizing reaction with air, thermopositive reaction just almost completely can not take place; Thereby, not only can prevent to follow the caused loss of thermopositive reaction of exothermic compositions, prevent the downgrade of exothermic compositions, can also prevent solidifying of exothermic compositions.Therefore, just can improve product percent of pass and operability greatly, the maintenance of manufacturing installation is more prone to, not have restriction working hour or operator's activity duration of manufacturing installation.

In addition, when if exothermic compositions is ink-like or cream pasty state, as top said, from making radiator body, to resulting radiator body is sealed to bubble-tight outside before the bag during this section in, almost completely do not have the oxidizing reaction with air, therefore, the steady quality that can make radiator body is just arranged, the advantage that its reliability is improved greatly.

In addition, the present inventor also obtains such knowledge, that is: because the exothermic compositions of this ink-like or cream pasty state is very stable in air, be resistance to air loss so also just there is no need to make mixing device.Also there is no need with the air in the nitrogen replacement mixing device,, thereby also just can make exothermic compositions and radiator body at low cost so mixing device easy to use gets final product.

In addition, the present inventor has also obtained such understanding, that is: as mentioned above, when using the exothermic compositions of ink-like or cream pasty state, by means such as printing or coating carry out transfer printing, stacked will be very easy, and can make the radiator body of ultra-thin shape at a high speed; And exothermic compositions is distributed in bag material equably, can also stop in the use or operation in the moving of exothermic compositions, biasing.

In addition, the present invention has also obtained such understanding, that is: by printing and the such laminating method of coating, this radiator body can be made extremely thin.Also promptly, radiator body is thin more, and the thermopositive reaction amount in the unit time is just low more, thereby has stoped the superfluous thermopositive reaction of exothermic compositions effectively.

In addition, the present inventor has also obtained such understanding, that is: by impregnation, spraying, mediate, the coating means of printing or coating etc., the viscous aqueous solution of water-retaining agent is laminated in foamed thin sheet, thin slice, paper, non-woven fabrics, weave cotton cloth or porous film, on the wrapping material such as thin slice, be dried, perhaps it is contained or be loaded with water-retaining agent by means such as crimping or kneadings, wrapping material are had after the water-absorbent, by means such as screen printing or coatings the exothermic compositions of ink-like or cream pasty state is duplicated again, thereon stacked, just can cancel the operation of casting of powder, thereby make factory's control of satisfying medical instruments in the future and the GMP standard in the pharmaceuticals manufacturing become simple and easy to do.

In addition, the present inventor has obtained such understanding, if i.e.: superfluous water or free-water, the perhaps part of the moisture of aqueous gel, by base material, coating material or be attached to ink-like or the water-absorbing material of the one or both sides of the exothermic compositions of cream pasty state etc. among at least a the absorption time, barrier layer has just been lost; When using, because exothermic compositions has become porous matter, and more good with contacting of air, also just can further obtain extremely excellent exothermic character.

The present invention finishes according to above-mentioned technology understanding just, the object of the present invention is to provide a kind of ink-like or cream pasty state exothermic compositions, with the radiator body that uses this exothermic compositions, and the manufacture method of this radiator body, dust takes place in the time of can preventing to make radiator body, in addition, can also suppress the thermopositive reaction of exothermic compositions, thereby prevent the loss that the thermopositive reaction when making causes effectively, prevent the downgrade of exothermic compositions and solidify; In addition, because what adopt is printing, transfer printings such as screen printing or coating, makes the uniform distribution of exothermic compositions become possibility, not only can improve constantly the thickness of exothermic compositions and the precision of distribution, realize the raising of quality product, can also make the radiator body of ultra-thin shape at a high speed easily; Then, can also by with the exothermic compositions transfer printing, be laminated to spongy base material, coating material or on the water accepting layer that forms on these base materials, the coating material, prevent that effectively exothermic compositions from moving, setovering; Add and to do one's utmost to avoid the excessive thermopositive reaction of exothermic compositions by the slimming of radiator body.

In addition, the object of the invention also is the ink-like or the cream pasty state exothermic compositions that provide following, and the radiator body that uses this exothermic compositions, and the manufacture method of this radiator body, Here it is, by impregnation, spraying, mediate, the coating means of printing or coating etc., absorptive viscous aqueous solution is laminated on the packaging material, row is dry again, perhaps by crimping, means such as kneading contain it, be loaded with water-retaining agent, just give packaging material with after the water-absorbent, again by means such as screen printing or coatings, the exothermic compositions of ink-like or cream pasty state is thereon stacked, so just eliminated the transfer printing process of powder, make factory's control of satisfying medical instruments in the future and the GMP standard in the pharmaceuticals manufacturing become simple.

In order to achieve the above object, the exothermic compositions of ink-like of the present invention or cream pasty state (below, abbreviate thing of the present invention as) be characterised in that, with exothermic ingredient, water-absorbing polymer and/or thickening material, charcoal composition and/or metal chloride and water is necessary composition, forms ink-like or cream pasty state as a whole.

In order to achieve the above object, radiator body of the present invention (to call radiator body of the present invention in the following text) is characterised in that, thing of the present invention is stacked, be sealing in the laminar wrapping material, these wrapping material have at least a part to have air permeability, and the portion of water of the invention described above thing can be absorbed by above-mentioned laminar wrapping material.

The manufacture method of the 1st kind of radiator body of the present invention (to call the present invention's the 1st method in the following text) is characterised in that, form thing of the present invention, this thing of the present invention is laminated in after the regulation zone at film like or at least one position above the laminar base material, by coated with film like or laminar coating material so that this thing of the present invention is covered, and have at least a side or a part to have air permeability among above-mentioned base material and the coating material.

The manufacture method of the 2nd kind of radiator body of the present invention (to call the present invention's the 2nd method in the following text) is characterised in that, form thing of the present invention, this thing of the present invention is laminated in after the regulation zone at film like or at least one position above the laminar base material, again at this above thing of the present invention, stacked or scatter by iron powder, that chooses in the middle of charcoal composition or the water-retaining agent is at least a, again with coating material with this thing of the present invention and from iron powder, at least a covering of choosing in the middle of charcoal composition or the water-retaining agent, and among the above-mentioned base material or coating material, have at least a side or a part to have air permeability.

The manufacture method of the 3rd kind of radiator body of the present invention (to call the present invention's the 3rd method in the following text) is characterised in that, thing of the present invention is laminated on film like or the laminar base material, face begins by coated with coating material from it then, viscosity by the invention described above thing, above-mentioned base material and coating material are fitted, then resulting duplexer stamping-out is become shape arbitrarily, and should have at least a side or a part to have air permeability among above-mentioned base material and the coating material.

Below to thing of the present invention and radiator body, and the present invention 1-3 kind method explains.

In the present invention, it is characterized by and be not to use in the past such Powdered thing, and be to use the exothermic compositions that makes its thickness turn to ink-like or cream pasty state, thing just of the present invention.

Like this, as thing of the present invention, so long as by can and airborne oxygen reaction, the composition that produces thermopositive reaction constitutes, and has in addition that external force just can mobile character get final product not qualification especially.

Specifically, for example be by being adjusted in each composition that constitutes thing of the present invention, water and water-absorbing polymer and/or thickening material, and the cooperation ratio of other compositions and.

Because thing of the present invention forms with ink-like or cream pasty state, thereby just can produce various advantages as described below.

That is to say, because thing of the present invention is ink-like or cream pasty state, thereby for example can utilize the thick well-known printing technologies such as printing, rotogravure printing, film printing, screen printing, spraying that are coated with to print, perhaps utilize the coating or the coating technology of head coater, roller, coating device etc., can carry out transfer printing, stacked easily, thereby produce the radiator body of ultra-thin shape with high speed, but also thing of the present invention is distributed on bag material equably.

In addition, if with thing transfer printing of the present invention, be laminated in foamed thin sheet, thin slice, paper, non-woven fabrics, weave cotton cloth or porous film, thin slice on, because the written or printed documents contrivance is ink-like or cream pasty state, so soak into, grappling is all very high, can infiltrate in the pore of these films or thin slice, prevent that it from moving, setovering, and and the contact area of air also significantly reduce, the air feed rate also significantly reduces, thereby also oxidizing reaction does not just take place almost completely.

In this case, particularly some films or thin slice have water-absorbent like this, thing of the present invention is laminated on these films or the thin slice, perhaps further on above-mentioned film or thin slice, form water accepting layer, on this water accepting layer during stacked thing of the present invention, this exothermic compositions whole or one one, can be firmly secured to this foamed thin sheet, thin slice, paper, non-woven fabrics more easily, weave cotton cloth or porous film, thin slice or the water accepting layer that on them, forms on, the result just can prevent moving of it or biasing.

In addition, carry out stacked method, can make this radiator body become thin in the extreme by screen printing or coating etc.In addition, radiator body is thin more, and the thermopositive reaction amount of unit time is just low more, thereby, can prevent the superfluous thermopositive reaction of exothermic compositions; Thing of the present invention is ink-like or cream pasty state, and bed thickness also as thin as a wafer, can stop moving, setovering of exothermic compositions.

In addition, by impregnation, spraying, coating means such as printing or coating, the viscous aqueous solution of water-retaining agent is laminated in foamed thin sheet, thin slice, paper, non-woven fabrics, weave cotton cloth, or porous film, on the flaky packaging material of thin slice etc., be dried again, perhaps by crimping, mediating to wait contains it, be loaded with water-retaining agent, just flaky packaging material is given after the water-absorbent, pass through screen printing again, or means such as coating, with thing transfer printing of the present invention, thereon stacked, just can not carry out powder and cast operation, make factory's control of satisfying medical treatment product in the future and the GMP standard in the pharmaceuticals manufacturing become simple.In addition, as above-mentioned water-retaining agent, mainly use following water-absorbing polymer or thickening material.

In addition, thing of the present invention is by further moisture fit rate, adding water-absorbing polymer and/or the thickening material of adjusting in the exothermic compositions, and thickness changes into ink-like or cream pasty state.By the transfer printing of printing, coating is carried out, stacked very easy, and can produce the radiator body of ultra-thin shape at high speed, and residual moisture constitutes barrier layer, thereby the feed rate of air is reduced, stopped thermopositive reaction in fact, this result, make it more stable in air, can further prevent the loss that heat release produced when making, prevent the decline of exothermic compositions quality, and the solidifying of exothermic compositions.

That is to say, the Powdered exothermic compositions in past, there is above-mentioned all great disadvantage, but resemble thing of the present invention and like this exothermic compositions thickness is changed into ink-like or cream pasty state, make transfer printing, stacked being more prone to by screen printing or coating etc., and can produce the radiator body of ultra-thin shape at high speed, and this residual moisture, free-water or aqueous gel can constitute barrier layer, so the feed rate of air reduces, and thermopositive reaction does not almost completely take place.

In this case, if the portion of water in residual moisture or free-water or the aqueous gel is absorbed by the bag material of base material and/or coating material etc., barrier layer is just lost, and, because the packaged material of moisture absorbs, make thing of the present invention become porous matter, better with contacting of air, thus can obtain the good radiator body of the present invention of exothermic character.

Thing of the present invention is to be must composition with the muriate of exothermic ingredient and water-absorbing polymer and/or thickening material, charcoal composition and/or metal and water, wholely forms with ink-like or cream pasty state; Its cooperation ratio is, exothermic ingredient for 100 weight parts, the water-absorbing polymer and/or the necessary composition such as the thickening material of 0.1-10 weight part, the charcoal composition of 1.5-20 weight part and/or the metal chloride of 1-10 weight part that add the 0.1-7.5 weight part, cooperate again with water, make its whole ink-like or cream pasty state of forming.

In this case, when making thing of the present invention, at first should only will form branch input mixing device admittedly, after treating that these compositions mix, to the aqueous solution that wherein adds entry or metal chloride or dispersion liquid, form ink-like or cream pasty state and get final product again, perhaps also whole compositions of exothermic compositions can be dropped into mixing device together, these compositions are mixed, form ink-like or cream pasty state.

Mixing device as these compositions, during excess moisture, the exothermic compositions of ink-like particularly, so long as can get final product by mixed uniformly device, not special the qualification, and for the fewer cream pasty state exothermic compositions of moisture, whipping apptss such as kneader or stirrer make exothermic compositions form the cream pasty state easily, and free-water or aqueous gel also cover the surface of exothermic ingredient easily.

Like this, thing of the present invention, as mentioned above, be to form ink-like or cream pasty state, its viscosity (20 ℃ of temperature), with following method, general preferred in the scope of 1000-7500000cps, if it is the viscosity of exothermic compositions is low excessively, low to 1000cps when following, then the transfer printing of the printing of exothermic compositions or coating just becomes very poor, excess moisture gets too much, the transfer printing quantity not sufficient of other compositions, and the heat release time is very short, exothermic compositions is exuded to outside the regulation zone on the base material, after the transfer printing, must make moisture, thereby must use the base material of special tectonic in large quantities by absorptions such as base materials, make the structure of radiator body also become complicated, thus not preferred; On the other hand, if surpass 7500000cps, then transfer printing variation, the transfer printing volume production is given birth to deviation, and the danger that produces thermopositive reaction on the surface is arranged, thereby not preferred.Therefore, from these reasons, preferably in the scope of 10000-6500000cps, in the scope particularly preferably in 50000-5500000cps.

Above-mentioned viscosity is meant, less than 2000000cps the time, is to use the VISCOMETER BH type viscometer of TOKIMEC INC system, adds the rotor of #7, and revolution is decided to be 2rpm, the value of using internal diameter to measure under 20 ℃ temperature for the beaker of (Φ 85mm); In addition, when surpassing 2000000cps, be to use R110 type viscometer (the RE110U system of eastern machine industry (strain) corporate system, detection head RE100U, controller RC100 A), use the SPP rotor, revolution is decided to be 0.2rpm (D=0.4 (1/S)), the value of measuring under 20 ℃ temperature.

In addition, this viscosity be transfer printing, the value when stacked.

Composition as thing of the present invention, with outside moisture or water-absorbing polymer and/or thickening material, the necessary exothermic ingredient of other compositions thermopositive reaction just in order to charcoal composition such as the charcoal that promotes heat release or gac and/or destroy the oxide scale film on metal powder surface, make its metal chloride that thermopositive reaction takes place continuously for must composition; As required, water-holding agent, the pH that can also be equipped with inorganic system or organic system adjust agent, improve dispersed tensio-active agent, defoamer etc., all form ink-like or cream pasty state.

The cooperation ratio of thing of the present invention, because of the kind of kind, exothermic ingredient and the charcoal composition of used water-absorbing polymer and thickening material, kind of metal chloride etc. different; Generally, for the exothermic ingredient of 100 weight parts, water-absorbing polymer is that 0.1-7.5 weight part, thickening material are that 0.1-10 weight part, carbon component are that 1.5-20 weight part and metal chloride are advisable for the 1-10 weight part; Particularly, in this mixture, add entry, make its whole ink-like or cream pasty state of forming.In this case, also the metal chloride of specified amount can be dissolved or dispersed in the water, it is joined in the mixture of being made up of water-absorbing polymer and/or thickening material and carbon component and/or metal chloride, make its whole ink-like or cream pasty state of forming.

In this case, also can above-mentioned solid form divide in addition an amount of water, and these all the components uniform mixing are obtained thing of the present invention, to replace only will forming the method that the branch uniform mixing adds the aqueous solution or the dispersion liquid of entry or metal chloride later on more admittedly.

Thereby even identical with above-mentioned situation in this case, the viscosity of thing of the present invention (20 ℃ of temperature) is with above-mentioned method, preferably in the scope of 1000-7500000cps.

In addition, thing of the present invention as mentioned above, by moisture and water-absorbing polymer and/or thickening material and other compositions just exothermic ingredient, carbon component and metal chloride etc. form, can access desirable exothermic character; In addition, for the further stability that improves temperature, and further increase the heat release time, water-holding agent, the pH that can be equipped with inorganic system or organic system again adjust agent, improve dispersed tensio-active agent, defoamer etc., whole more at last ink-like or the cream pasty state of forming like this can be more effective.

That is to say,, add water-absorbing polymer, the thickening material of 0.1-10 weight part, the carbon component of 1.5-20 weight part and the metal chloride of 1-10 weight part of 0.1-75 weight part for the exothermic ingredient of 100 weight parts; Further, in this exothermic compositions, cooperate with pH and adjust choose in the middle of the defoamer of the tensio-active agent of raising dispersiveness of agent, 0.1-5 weight part and 0.1-5 weight part at least a from the water-holding agent of the inorganic system of 0.5-10 weight part or organic system, 0.1-5 weight part, thing of the present invention, in this mixture, add water and make its whole ink-like or cream pasty state of forming, in this case, preferably the metal chloride with specified amount is dissolved or dispersed in the water, join again in the said mixture, make its whole ink-like or cream pasty state of forming.But, add an amount of water in also can dividing, and these whole composition uniform mixing are obtained thing of the present invention in above-mentioned solid formation, after replacing previous will form the branch uniform mixing admittedly, add the method for the aqueous solution or the dispersion liquid of entry or metal chloride again.

Therefore, coating material, what be covered is thing of the present invention, by at least a and water-absorbing material of choosing in the middle of iron powder, charcoal composition or the water-retaining agent.

In the present invention's the 2nd method, because what obtain is by with contacting of air and the radiator body of the present invention of heat release, so wrapping material of forming by above-mentioned base material and coating material, at least want some to have air permeability, in addition, identical as what illustrate in base material and coating material and the radiator body of the present invention, for avoiding repetition, no longer explanation here.

That is to say, the present invention's the 2nd method, be in the present invention's the 1st method, stacked or spill at least a that cloth chooses in the middle of iron powder, charcoal composition or the water-retaining agent on thing of the present invention, then again by coated with film like or flaky coating material, so that at least a covering of choosing with this present composition with in the middle of iron powder, charcoal composition or the water-retaining agent, other each points are then identical with the present invention's the 1st method.For avoiding repeating no longer to illustrate here.

Say bright the present invention's the 3rd method of describing in detail below.

The present invention's the 3rd method, stacked thing of the present invention on film like or flaky base material at first, then be covered thereon film like or flaky coating material are by the viscosity of the invention described above thing, at the one or both sides adhered film shape or the flaky water-absorbing material of thing of the present invention again.

In the present invention's the 3rd method, as the thing of the present invention that is adopted, can enumerate with above-mentioned identical, for avoiding repeating no longer to describe in detail here.

The present invention's the 3rd method, identical with above-mentioned situation, for before the portion of water that can make thing of the present invention absorbed by absorptive base material and/or coating material, even if contact with air, the oxidizing reaction that also can suppress thing of the present invention, thermopositive reaction just, the loss of the exothermic compositions that the thermopositive reaction when preventing because of manufacturing conscientiously causes, prevent the downgrade of exothermic compositions and solidifying of exothermic compositions, because thing of the present invention forms with ink-like or cream pasty state, so can be stacked with homogeneous thickness, add thing toughness of the present invention, energy and wrapping material are bonding, so can prevent moving of exothermic compositions, biasing, and can also do one's utmost to avoid the thermopositive reaction of the surplus of exothermic compositions.

In the present invention's the 3rd method, as the method for stacked thing of the present invention on base material, not special the qualification, specifically, that can enumerate has, for example the coating of coating machine, roller coat, coating device etc. such as head cater etc.

In the present invention's the 3rd method, because what obtain is by with contacting of air and the radiator body of the present invention of heat release, so among the above-mentioned base material and coating material, should have at least a side or a part to have air permeability.In addition, can be used as above-mentioned base material and coating material, with introduced in the radiator body of the present invention identical, for avoiding repetition, no longer explanation here.

In the present invention's the 3rd method, be resulting duplexer to be die-cut into arbitrary shape just can obtain radiator body, therefore base material and coating material preferably can be easy to carry out this die-cut material, and on this viewpoint, this base material and coating material preferably can form with stationery.

Above-mentioned duplexer is die-cut into the operation of regulation shape, carry out after can making this duplexer static, in this case, can carry out die-cut simultaneously at direction of feed and width rectangular several duplexers simultaneously arranged side by side of duplexer with it, just can once form the radiator body of volume, thereby reduce cost greatly.

But this method, as previously mentioned to for example flaky base material of drum film like or drum, with for example 160-200 rice/minute the speed feeding time, behind the stacked thereon thing of the present invention, with the coating material of web-like film or rolled sheet thereon, coating material is coated on the thing of the present invention again with rail guidance.Obtain duplexer by this method, carry out after die-cut operation stops duplexer.In case duplexer is wound into web-like, must makes this coiled material repeat off and on just can carry out when die-cut.So just not only make manufacturing process become complicated, manufacturing time prolongs greatly, and because die-cut operation is intermittently, and the raising of operating efficiency is certainly led to a restriction.

Therefore, in the present invention's the 3rd method, manufacturing process is simple in order to make, manufacturing time shortens, and the speed of feed in the time of duplexer can being carried out this manufacturing for example is adjusted to the speed feeding with per minute 160-200 rice, simultaneously, adopt the roll-type punch press to be die-cut into shape arbitrarily.Preferably obtain radiator body of the present invention by this method.

Like this, when using the roll-type punch press, not only can the continuous cutting duplexer, make the manufacturing of duplexer and die-cutly work continuously consistently, but also can make the radiator body of volume at short notice, the result, compare with making the static die-cut again method of duplexer, can reduce cost significantly.

In addition, in this case, a position or two above continuous cuttings in position on the width of duplexer, or on the longitudinal direction of duplexer several spinations of continuous cutting, just can make the more radiator body of the present invention of volume at short notice, further reduce cost significantly.

About the die-cut shapes of this duplexer, the difference according to the purposes of the radiator body of gained can be die-cut into the shape that can cover any part.

That is to say that in the present invention's the 3rd method, resulting duplexer can become desirable arbitrary shape by stamping-out, with the radiator body of the present invention of this stamping-out gained, can be sufficient usefulness, shoulder with, waist usefulness, do not limit especially, can be shape arbitrarily.

The present invention's the 3rd method, can be by the viscosity of thing of the present invention, base material and coating material are fit together, after having carried out this applying, portion of water can be absorbed by base material and coating material, and this radiator body can be enclosed among the housing material of non-air permeability the supply circulation.The result can just keep this state as merchandise sales.

But, had better be with radiator body of the present invention through this stamping-out, sandwich between two films or the thin slice, and when sandwiching, perhaps after sandwiching, two films or thin slice stamping-out are become the shape bigger than the present invention radiator body, in stamping-out, perhaps after the stamping-out,, above-mentioned two films or thin slice are shut at the circumference of the invention described above radiator body.

In this case, because employing is to have at least a side or a part to have air permeability among above-mentioned two films or the thin slice, so just can obtain the higher radiator body of the present invention of reliability.

That is to say, can obtain the radiator body of the present invention of arbitrary shape by this operation, still, supply with the air capacity of the exothermic compositions that is positioned at the inside, all is to be controlled by the air permeability of these two films.Therefore, identical to the air permeability control of thing of the present invention with the ventilation control of base material and/or coating material in the radiator body of the present invention, be that benchmark is controlled with the water vapour permeability.In addition, this Water Vapour Permeability, just with two films among a slice film, and the stacked film of base material and coating material or the Water Vapour Permeability of thin slice, identical with the situation of thing of the present invention and radiator body of the present invention, for avoiding repetition, no longer be elaborated herein.

Above-mentioned two films or thin slice can be non-air permeabilitys, also can be air permeability, and these materials also should have Thermoadhesive or hot melt property except binding property is arranged.

As above-mentioned fusible film or thin slice arranged, can be in base film or basic thin slice, its whole surface is formed the bonding coat of air permeability with the tackiness agent of heat fusing system, perhaps its whole surface is formed the bonding coat of part air permeability or non-air permeability, no matter and whether this base material film or sheet of base material itself have Thermoadhesive or hot melt property.

In the present invention's the 3rd method, so long as after when the formation of the radiator body of this rectangular shape, again before the radiator body to this rectangular shape carries out stamping-out, perhaps when the radiator body to rectangular shape carries out stamping-out, perhaps after the radiator body stamping-out of rectangular shape, at the circumference of radiator body, with two films or thin slice sealing-in.

Here, so-called stamping-out becomes the shape bigger than radiator body, as long as more than the size of this radiator body, and not special the qualification.But preferably similar with the shape of radiator body, perhaps similar haply, the big shape of formation goes out several millimeters to 20 mm wides than this shape is wide on its whole periphery.

Like this, utilize the present invention's the 3rd method, just can this epitaxial part of sealing-in, just use the method for bonding, heat bonding or heat fusing, above-mentioned two films or the thin slice of radiator body circumference are sealed up.

But in above-mentioned the present invention 1-the 3rd method, preferably either party face that exposes of radiator body of the present invention forms binder layer comprehensively or partly, and this any one party, or at least a portion of the opposing party should have air permeability.

This binder layer can be the wet layer of cloth that contains wet-cloth agent, or contains or be loaded with the medicated layer of Percutaneously absorbable medicine, and also all the situation with radiator body of the present invention is identical for these, for avoiding repetition, and no longer explanation here.

This binder layer can contain or be loaded with far-infrared emitter, or magnetic substance in the middle of at least a.

In addition, in the invention described above 1-the 3rd method, resulting radiator body, begin from its manufacturing to come into operation this section during in, portion of water in the thing of the present invention is absorbed by base material and/or coating material or the water-absorbing material that is attached on the one or both sides of thing of the present invention, free-water in the thing of the present invention, the perhaps portion of water in the aqueous gel, the water-absorbing material that is attached on the one or both sides of thing of the present invention absorbs.This result can obtain porous matter, and is good with contacting of air, and in case can rapid generation thermopositive reaction when contact with air.

Further, when using it, exothermic compositions 2 can not move, and the exothermic temperature of radiator body of the present invention is evenly distributed, and does not have low temperature to scald, and security is higher.

In addition, although diagram and the 4th embodiment have not similarly made radiator body of the present invention in order to being heated in the back.

The invention described above thing 2, to the iron powder of the exothermic ingredient of 100 weight parts (with and iron powder corporate system DKP), mixing is with the gac (NORID corporate system SA-SUPER) of 7.0 weight parts, 2.0 the diatomite as water-holding agent of weight part (wafer), 1.4 the thickening material of weight part (the first industrial drugmaker system, trade(brand)name Cellogen EP), 0.3 the water-absorbing polymer of weight part (Sanyo changes into corporate system trade(brand)name SANWET IM-5000 MPS), 5.0 weight part as the sodium-chlor of metal chloride and 0.3 weight part adjust the tripoly phosphate sodium STPP of agent as pH, the viscosity when again this title complex being added water with 20 ℃ of temperature is adjusted to about 2,500,000 CPS.

That is to say, adjust the order of agent and sodium-chlor according to gac, diatomite, thickening material, water-absorbing polymer, pH, and, drop into mixing machine (special machine chemical industry Co., Ltd. system with above-mentioned cooperation ratio, T.K.HIVISMIX 2P-100 type, 100 liters of capacity).After adding a cover into sealed state, with the revolution rotation of 10rpm, cast iron powder from dog-house simultaneously, restir three minutes continues to cast water when stirring, and revolution is risen to 15rpm, mixes after five minutes, temporarily stops.

Then, after the dirt settling of the blade that has cleaned mixing machine, shell, mixed five minutes with the 1rpm revolution once more, carry out viscosimetric analysis and specific gravity test, carry out the moisture adjustment, making viscosity is after reaching 250CPS with following method mensuration, in this case, and for the iron powder of 100 weight parts, (same and iron powder corporate system DKP) moisture is 42.0 weight parts, resulting thing of the present invention, proportion are 2.428g/ml, and viscosity is 2,520,000 CPS.

With this thing of the present invention, preservation is after one hour down at 10 ℃, and viscosity can rise to some extent, when mixing once more, is 2,550,000 CPS with following method viscosimetric, by screen printing it is laminated on the base material 3.

In this case, the revolution of blade carries out with 10rpm.

This viscosity is the R110 type viscometer RE110U system (detection head RE100U, controller RC100A) with eastern machine industry (strain) corporate system, and uses the SPP rotor, and revolution is 0.2rpm (D=0.4 (1/SD)) measures gained under 20 ℃ temperature a value.

Therefore, this thing 2 of the present invention can be used as barrier layer and plays gel and iron powder and the contacted function of air that obstruction contains free-water or moisture, and this result can be known as and almost completely not produce thermopositive reaction.

With resulting radiator body of the present invention, be sealing in the non-air permeability bag, and after it was placed ten days, break non-air permeability pocket, take out this radiator body of the present invention, then use binder layer 5, when it directly is attached to the back use, can obtain reaching the extremely excellent warm effect more than 6 hours.

When suitable the invention described above radiator body,, be unusual softish so do as a whole because this radiator body forms with ultrathin type.As a result, can make its thoughts and feelings very soft, can finely follow the action of the back of the body and be out of shape the back of the body, also very good to the adaptation that is suitable for the position; Radiator body of the present invention in addition in use can not strip down from being suitable for the position, generally acknowledges to obtain extremely excellent heating effect that it is warm that shoulder is obtained.

Secondly, in use, exothermic compositions 2 can not move, and the exothermic temperature of radiator body of the present invention is evenly distributed, and does not have low temperature to scald, and security is high.

Carry out the heat release experiment with following method.

Iron powder (same and iron powder system DKP) to 70 weight parts, add 10 weight parts as the gac (NO RID preparing active carbon GL-50) of charcoal composition, the sodium-chlor as metal chloride of 2 weight parts, the thickening material (the chemistry system METOROSE 60SH-4000 of SHIN-ETSU HANTOTAI) of 0.7 weight part, tensio-active agent (Kao Corp's system of 0.2 weight part, trade(brand)name: DEMOLEP) pH with 0.1 weight part adjusts agent (tripoly phosphate sodium STPP), add excessive water, be modulated under 20 ℃ temperature, viscosity is the ink-like of 10,000 CPS and 6,800,000 CPS or the thick liquid of cream pasty state.

Using viscosity is the thing of the present invention of 10,000 CPS and the thing of the present invention that viscosity is 6,800,000 CPS, as shown in Figure 6, this exothermic compositions is packed in the beaker 10 of 200ml, and the D place, position that respectively temperature sensor 11 is inserted 10mm under its surface and the centre surface measures its temperature variation.

Its result, viscosity are the exothermic compositions of 10,000 CPS, and surface and central authorities can't see temperature to rise fully about 20 minutes.But viscosity is the exothermic compositions of 6,800,000 CPS, and the surface can see that the temperature about five minutes rises, and centre almost completely be can't see the temperature rising about five minutes.

On the other hand, as a comparative example, the exothermic compositions of using the wood powder by the gac of the salt solution of 10% (weight) of the iron powder of 60 weight parts, 25 weight parts, 13 weight parts and 14 weight parts to constitute.Iron powder, salt and gac use and the same product of the foregoing description.

Use this exothermic compositions, when carrying out with above-mentioned same heat release experiment, this exothermic compositions, the temperature rising is all seen at surperficial and central two places at once, temperature is just above 60 ℃ about two minutes.

Among the present invention, also the foregoing description 1-3 can be used in combination.In addition, can also be at the one or both sides of thing of the present invention, adhered film shape or the high stationery of laminar water-absorbing material, particularly water-absorbent in the portion of water that absorbs thing of the present invention, can also make thing of the present invention be fixed in more firmly on this stationery.

As discussed above, the exothermic compositions relevant with the present invention, be that thickness changes into ink-like or cream pasty state, therefore, can these exothermic compositions be laminated on the base material by printing or coating etc., and can also control lamination area accurately, with extremely thin thickness, equably thing of the present invention is laminated on the base material, this result, can obtain can be to make the effect of the radiator body of the present invention of ultra-thin shape at a high speed.
