Description

Gas stop resin formation body
Technical field
The invention relates to novel gas stop resin formation body and choke transparent membrane.In more detail, the invention relates to and to be applicable to novel gas stop resin formation body and the choke transparent membrane of liquid crystal display with substrate and packing material.
Background technology
To minimum gas stop resin formation body and choke transparent membranes of gas permeability such as oxygen, nitrogen, carbon dioxide, water vapor, the needs in fields such as packing material increase.Packing material for such food, beverage product container and wrappage etc., in order to give formed body material gas barrier properties such as plastic sheeting or sheet material, present known following several method, (1) forms formed body with air impermeability raw materials such as ethylene-vinyl alcohol copolymer, vinylidene chloride analog copolymer, aromatics nylon; (2) with these air impermeability raw material laminations or be coated on other material; (3) at film like material upper strata jewelling paper tinsel; (4) method of vacuum coating metal and metal oxide etc.
Yet, in the middle of the air impermeability raw material in (1) and (2), exist the moisture-proof of ethylene-vinyl alcohol copolymer and fragrant same clan nylon poor, and rising along with temperature in the atmosphere, descend the significantly problem of (the humidity interdependence of gas barrier property is big) of gas barrier property, and, worry to become public hazards because the vinylidene chloride analog copolymer contains the chlorine atom.And, with the packing material that the aluminium foil laminate film in (3) is manufactured, can not see the content of packaging from the outside, and the metal of the vacuum coating in (4) and metal-oxide film, on vacuum coating, crack easily owing to its subduing property difference.There is the problem that causes that gas barrier property reduces.
In addition, for allowing to use gas stop resin formation body and choke food, the beverage product of transparent membrane that obtain thus as the packing material of container and wrappage etc., the consumer will endure strict scrutiny when shopping, for example, because base material and choke are bad with the adaptation between the overlayer, with subduing property problem is arranged, cause easily and peel off, transparent variation; And for the bad packing material of printing, no matter how and the no one buys the quality of food, beverage product itself, the phenomenon of not going out, return goods will occur selling.So we can say, for requiring extremely strictness of benchmark with transparent membrane as the gas stop resin formation body of the container of food, beverage product and wrappage etc. and choke.Except that gas barrier property, also seeking the performance with high requests such as base material adaptation, the transparency, subduing property, printing, moisture-proofs, so the task of top priority is exactly gas stop resin formation body and choke transparent membrane that exploitation can be had both the new raw material of above-mentioned various characteristics.
Also have, this gas stop resin formation body and choke are used as the food of the packing material of container and wrappage etc. for permission with transparent membrane, the beverage product, from the fabricator, the peasant, the transporter is between the ultimate consumer, (comprise commercial warehouse by the wholesale stage, the wholesale dealer, wholesale facility, the food market, circulations such as container warehouse, the logistics stage), the circulation number of times in retail stage is also many, also there is the consumer time and again article to be placed on evaluation on hand in the retail stage, so for the gas stop resin formation body and the choke transparent membrane that are used for container and wrappage etc., demanding flexible resistance.That is to say, because before the consumer is buying permission use gas stop resin formation body and the F﹠B product of choke usefulness transparent membrane as container and wrappage etc., following phenomenon appears sometimes: container and wrappage that gas stop resin formation body and choke are made of transparent membrane, the wrinkle that perhaps becomes gauffer pleat, perhaps when state is rolled in bending, pack, under cold insulation temperature (5 ℃ of temperature) condition, display; Perhaps when taking and when evaluation packaged food, beverage product are squeezed or bending is rolled over, the gauffer pleat of wrinkling becomes.Being in bending repeatedly and often under such low temperature environment is subjected under the folding state, when being used for the gas stop resin formation body of the container of food, beverage product and wrappage etc. and choke with the not enough situation of the flexible resistance of transparent membrane, worry duck eye and crackle etc. to occur, just can not guarantee desirable gas barrier property in the quality guarantee period (appreciating the taste time limit) at food, beverage product.Thereby cause in food, the beverage product content oxidation, variable color, cause in the shelf-life food, beverage product quality to descend.So flexible resistance just becomes one of extremely important necessary requirement performance.Especially spring rate (length growth rate), the disparity when the transparent plastic film of base material and choke are rolled over the bending between the variety classes resin material of coating seems under the big situation, even give choke with desirable bendability on the coating, the flexible resistance of gas stop resin formation body and choke usefulness transparent membrane also not enough, so must select to use with desirable choke uses the transparent plastic film of coating compatibility good (length growth rate is roughly the same) as base material, therefore, its use also is restricted.Here, when not limiting (selection) as gas stop resin formation body and choke during, need exploitation to be rich in versatility strongly, can satisfy the material of gas barrier property and other performance requirement with the base material of transparent membrane.
In addition, display device from notebook personal computer and Word message processor, also subsidiary liquid crystal on minitelevision, scavenger and radio cassette recorder, clock and watch etc., the telephone set display device that comprises mobile phone, the time showing of cooker, カ one Na PVC, game machine even, the many goods in our present daily life have all used liquid crystal indicator (liquid crystal display).Here it is because liquid crystal display is compared with other demonstrations, and it is few to have when showing the electric power of required consumption, and be easy to advantage such as miniaturization and.
Especially, for carrying end and even モ バ ィ Le machine (mobile phone, mobile information end (PDA), carry and use notebook personal computer, pocket radio pager, automobile telephone etc.) etc., from Portability and the little viewpoint of consumed power, machine miniaturization and more just becomes the theme that important technology is developed, as wherein one encircling, with regard to liquid crystal indicator, with the display board of glass in the past, weight is big, and, developing with light-duty owing to the problem such as break of the impulsive force when falling down or run into hard thing, solid thin polymer film is as the LCD of substrate.Use this with the liquid crystal display of thin polymer film as substrate, compare with glass substrate, have very light and can make very thin, resistance to impact is also strong, can be shaped to arbitrary shape (for example being molded into curve form), also can make hyalinosis's advantages of higher, be the market at center so enlarging with mobile phone etc. significantly.In addition, mobile phone with internet connection function is popularized rapidly, in next-generation mobile phone, the sound acoustic intelligence of the high speed communication of high capacity writings and image information becomes possibility than having more originally, so, the exploitation of the large-scale liquid crystal board that more writings and image information can once show becomes the thing of the task of top priority, and the more slim and exploitation that have a thin polymer film substrate of high reliability of light weight just becomes important.
So-called liquid crystal enters layer, owing to the thickness that makes liquid crystal layer necessarily forms and extraneous negative pressure, once the substrate gas barrier property degenerates, the permeability height, oxygen and water vapor will enter in the liquid crystal, a certain amount ofly will produce bubble if enter certain, even energising is not replied yet, just become China ink and dye.Therefore, in this thin polymer film substrate, gas barrier property just becomes important factors, till up to now, develop, in the middle of the commercially available commodity, almost on base film, can form the thin polymer film substrate of gas barrier layer, usually can form with certain certain proportion under the state (below, also only be called the lower negative pressure state) of negative pressure at liquid crystal layer, just can cut off gases such as air and water vapor.Yet, in in putting into school bag and pocket etc. and in operation, can push or be extruded liquid crystal watch panel (film), when after applying load, cancelling this load, return between the speed (recovery speed) of previous status and the speed that inner liquid crystal returns to original state in surface plate and to have difference, because it is slow that liquid crystal restores speed, the liquid crystal aspect form for the moment higher negative pressure state (below, also only be called the high negative pressure state), gas permeation just occurred and had gas barrier layer surface plate (film), in the inner problem that forms bubble of liquid crystal, therefore, for such surface plate (film), remove in light weight, beyond solid, also require in gas barrier layer in the past inaccessiable, when under service conditions such as liquid crystal side is extruded, forming the high negative pressure state, gas can not see through, so higher gas barrier property is necessary.
In addition, the flat pannel display of the mode of new generation of these LCD instead, PDP (Plasma Display panel), the PDP of exchange way, plasmatron, the LED that have proposed FED (light emitting-type flat pannel display voluntarily), direct current mode show (diode displaying) or the like, also propose not use the new display of liquid crystal.Because it is few to have a consumed power, thin thickness, advantage such as answer speed is fast, and no angle of visibility is interdependent is so as long as we can say the manufacturing cost problem that solved, just containing these advantages as the extensively universal possibility of desirable display.
Even such display, though aspect substrate, also can use glass substrate, but compare with glass substrate, owing to have the very light and thin thickness of weight, impact resistance is strong, can be molded into arbitrary shape, (for example being molded into curved surface), transparency advantages of higher is so wish to utilize and the same thin polymer film substrate of LCD always.
Yet the battery with between liquid crystal replacement substrate must make plasma discharge with mercury vapour and xenon, and perhaps ejected electron makes phosphor body luminous.Therefore since in battery from outside permeate water steam and oxygen, be difficult to cause that plasma discharge and electronics emit, cause equally with liquid crystal and cause malfunction.Thereby such display and liquid crystal display are same, and it is consistent requiring that for substrate high gas barrier property aspect is arranged, if adopt the thin polymer film substrate, described gas barrier property just becomes important factors.Under various environments for use, for example under high temperature, high humidity service condition, the high gas barrier property aspect that requirement can fully be fit to, with LCD also without any different.

In addition, this suitable coating composition is exactly to comprise organic high molecular compound (I), organic compound (II) as mentioned above, contain organosilyl compound (IIIb) and solvent (IV) is a raw material, the content that contains organosilyl compound (IIIb) in the total amount of wherein aforementioned (I)+(II)+(IIIb) is more than 50 quality %, preferred 50-80 quality %, more preferably 50-70 quality % is as the coating composition of raw material.In addition, the non-volatile content concentration of the coating composition that this is suitable is more than 5 quality %, preferably more than 7 quality %, more preferably more than 10 quality %, and the content of the organo-silicon compound (III) in this suitable coating composition is below 3 quality %, preferably below 2 quality %, more preferably below 1 quality %.
The content that contains organosilyl compound (IIIb) in the total amount of aforementioned (I)+(II)+(IIIb) less than 50 quality % in, the moisture-proof of coating is just bad.Should not be subjected to special restriction for the use level that contains organo-silicon compound (IIIb) in the total amount of aforementioned (I)+(II)+(IIIb) on the other hand, but in greater than 80 quality %, tectal subduing property is just bad.
When the non-volatile content concentration in this suitable coating composition less than 5 quality % the time, the explained hereafter when forming coating is bad, perhaps because effective constituent concentration is low excessively, therefore the thickness that can not guarantee necessary coating is just arranged.On the other hand, the upper limit for non-volatile content concentration, should not be subjected to special restriction, but the time greater than 30 quality % situations, the volatile matter concentration of solvent (IV) etc. is low, therefore during coating processes, when the viscosity rising of this suitable coating composition, the possibility that can not homogeneous applies is just arranged, and the reaction stability of this suitable coating composition is bad.
In addition, when the content of the organo-silicon compound (III) in this suitable coating composition greater than 3 quality % the time, apply after this suitable coating composition organo-silicon compound (III) evaporation during drying, because condensation reaction is difficult for effectively stably handling in coating.Therefore, except that the constituent of coating not necessarily, can not keep consistently the high-performance because the dispersing of the organo-silicon compound of specially giving a long price for (III), and cause waste.In addition, because the evaporation of low-boiling these organo-silicon compound (III) and dispersing, the viscosity of this suitable coating composition is also changed (be owing to make in batches, form not necessarily, also one of dissimilar reason of performance).And for the lower limit of organo-silicon compound (III) content in this suitable coating composition, should not be subjected to special restriction, according to the raw material gradation composition and the use level that contain organosilyl compound (IIIb), further according to thereafter add water decomposition condensation reaction etc., to the full dose that contains organosilyl compound (IIIb) in the resulting coating composition is to add the composition that water decomposition condensation product etc. obtains by adding water decomposition condensation product (IIIa) and organic compound (II) and (being total to), even organo-silicon compound (III) content is that 0 quality % is good.
The coating composition that this is suitable, further, the total light transmittance at optical path length 1cm place is more than 80%, and is preferred more than 85%, more preferably is desirable more than 90%.
Like this, for coating composition of the present invention, in case the polyreaction (adding the water decomposition polyreaction) and the response competition that depolymerizes, the words that polyreaction (adding the water decomposition polyreaction) is too carried out just cause and cause the particlized phenomenon.If use the coating composition that has this particle, will resulting gas barrier property be reduced with the transparency of resin-formed body owing in resulting coating, comprising heterogeneous particles.In addition, just do not have continuity as forming (tissue and even tectosome), and become inhomogeneous.Also, become the destruction face because this particle is hard.Therefore in the middle of the resin-formed body of resulting gas barrier property, with regard to adaptation, the transparency, gas barrier property, subduing property, the printing bad problem of generation with base material.So, if the optical path length of the coating composition of above-mentioned raw materials (cooperation) composition, adds the water decomposition polyreaction and carries out with regard within reason more than 80% at the total light transmittance at 1cm place, add water decomposition polyreaction appropriateness, therefore also not causing to cause the particlized phenomenon, is desirable.
In addition, as mentioned above, in the coating composition in the present invention, when comprising organic high molecular compound (I) and organic compound (II) as the situation of raw material (A), can comprise macromolecular compound (I) and organic compound (II) potpourri, organic compound (II) add any in water decomposition condensation product, macromolecular compound (I) and organic compound (II) reactant.In addition, comprising macromolecular compound (I), organic compound (II), when further including organic silicon compound (III) as the situation of raw material (B), above-mentioned organic compound (II) and organo-silicon compound (III) be add the product of water decomposition condensation reaction in advance, also be the product that adds the water decomposition condensation reaction altogether, can also comprise macromolecular compound (I) and the reactant that reacted in any.For example, when above-mentioned (A) situation, above-mentioned organic compound (II) can be with the reaction of macromolecular compound (I) before or carry out after the reaction add the material that the water decomposition condensation reaction obtains; When above-mentioned (B) situation, further, above-mentioned organic compound (II) can comprise that adding water decomposition condensation base adds the material that the water decomposition condensation reaction obtains together.
As above-mentioned by the modulator approach of coating composition, should not be subjected to special restriction, when above-mentioned (A) situation, even before the reaction of macromolecular compound (I) and organic compound (II), carry out organic compound (II) to add the water decomposition condensation reaction good, even it is good perhaps to add the water decomposition condensation reaction after the reaction of macromolecular compound (I) and organic compound (II).In addition when the situation of above-mentioned (b), even before the reaction of macromolecular compound (I) and organic compound (II), carry out organic compound (II) and organo-silicon compound (III) to add the water decomposition condensation reaction altogether good, even perhaps after the reaction of macromolecular compound (I) and organic compound (II), add organo-silicon compound (III), it is good or the like that organic compound (II) and organo-silicon compound (III) add the water decomposition condensation reaction altogether.For carrying out time and the interpolation time of each composition, the restriction especially that (I) and reaction (II) and (being total to) add the water decomposition condensation reaction.
In addition, about comprising above-mentioned macromolecular compound (I) in order to modulate conduct, organic compound (II), contain organosilyl compound (IIIb), the raw material of solvent (IV), wherein 50 quality % in (I)+(II)+(IIIb) total amount are above for containing organo-silicon compound (IIIb) reaction, and the non-volatile content concentration in the resulting coating composition is more than 5 quality %, and make organo-silicon compound (III) in this coating composition below 3 quality %, further preferred, total light transmittance at light path line 1cm place is the modulator approach of the suitable coating composition more than 80%, should not limit especially equally with above-mentioned, but in order to adjust the progress that adds the water decomposition condensation reaction of organo-silicon compound (III), according to the suitable conditioned reaction temperature of each modulator approach, reaction time is desirable.But these temperature of reaction and reaction time, except following illustrated because of its modulator approach (mainly making reaction carry out the aspect) difference, because the combination difference of the kind of use raw material etc., so can not unify regulation, but can and use according to each modulator approach and cooperate raw material, the simple preliminary experiment of the chamber level that experimentizes in advance can be understood temperature of reaction and reaction time in order to satisfy above-mentioned condition of the present invention simply.At this moment, the non-volatile content concentration in the above-mentioned coating composition of known quantivative approach simple knowledge such as available vapor-phase chromatography and the content of organo-silicon compound (III).
That is to say, adopt the modulator approach of above-mentioned suitable coating composition, the above-mentioned raw materials composition is reacted, adjust the progress that adds the water decomposition condensation reaction of organo-silicon compound (III), according to the content of non-volatile content concentration in the coating composition of afore mentioned rules and organo-silicon compound (III), suitable adjustment temperature of reaction, reaction time etc. allow.With regard to making the reaction mode (reactive mode) of carrying out, material composition is once reacted, material composition is reacted etc. stage by stage, should not limit especially.In addition, with regard to adjust the means of above-mentioned 2 necessary conditions according to reaction, be exactly according to kind and use level and the reactive mode of using material composition, the necessary temperature of reaction that decision suits, reaction time, stirring rate, raw material input speed etc.And as hereinafter described the embodiment example like that, adding water according to reaction, to make reaction be desirable.In addition, so-called " adding water carries out reaction " both just was meant and can as solvent (IV) reaction carried out separately with water, also can as solvent (IV) reaction be carried out with the mixed solvent that water and other solvents (more than one) form, as long as use (interpolation) moisture at least solvent, reaction is carried out just.Representative method in the modulator approach of the coating composition that following example is suitable (mainly being the mode that reaction is carried out).Can enumerate:
(1) simple mixing comprises above-mentioned macromolecular compound (I), above-mentioned organic compound (II), contains the above-mentioned method that contains the gradation composition (even it is good to comprise other any compositions) of organosilyl compound (IIIb) and solvent (IV);
(2) in advance in the presence of solvent (IV), make after the functional group of above-mentioned macromolecular compound (I) and above-mentioned organic compound (II) reacts, add the above-mentioned method that contains organosilyl compound (IIIb);
(3) in the presence of above-mentioned macromolecular compound (I) and solvent (IV), make above-mentioned organic compound (II) and the above-mentioned organo-silicon compound (III) that contain in the organosilyl compound (IIIb) carry out the method that (being total to) adds the water decomposition condensation reaction;
(4) in the presence of solvent (IV), making above-mentioned organic compound (II) and the above-mentioned organosilyl compound (III) that contains in the organosilyl compound (IIIb) carry out (being total to) adds after the water decomposition condensation reaction, make method of reacting or the like, in this any restriction that not given an example by these with above-mentioned organic high molecular compound (I).
In addition, wish, replenish and even append in good time above-mentioned solvent (IV) according to its stage of modulating and method.And add in the water decomposition condensation reaction above-mentioned, can use known catalyzer, and to make reaction in solvent (IV) be favourable.Especially, preferably make organo-silicon compound (III) and organic compound (II) add the water decomposition condensation reaction altogether in advance.In addition, as described later, wish to make suitable coating composition after being coated on the base material, harden, drying, add organic silicon compound (III) in the water decomposition condensation coating composition etc.
Method as the coating that above-mentioned coating composition is formed, be not particularly limited, can adopt over known coating (coating processes) method, promptly after the last coating of base material (layer when between base material and coating the middle layer being set) uses solvent (IV) to be modulated to certain density coating composition, carry out by the drying of overlay film (sclerosis), form coating, but further, the coating that preferred maturation process forms.Below, more be described in detail.
At first, as going up the painting method that applies coating composition at base material (layer when between base material and coating, the middle layer being set), should not limit especially, can suit to utilize the existing known film formation technology that is suitable for the base material shape, (coating processes or the coating) technology of coating, for example can adopt the cylinder cladding process, the immersion coating method, bar cladding process (バ one コ one テ ィ Application ぐ method), the nozzle cladding process, the pressing mold cladding process, the spray application method, spin coating method, curtain cladding process (カ one テ Application コ one テ ィ Application ぐ method), the flow coating method, reticulated printing, photogravure, the various printing processes of flexography etc. etc., perhaps these combination.Wherein, consider that with the stable aspect that applies agent the pressing mold cladding process is preferred from increasing choke.
Secondly, after applying above-mentioned coating composition, dry (sclerosis) films.For described drying (sclerosis) method,,, be preferred forming the good fine and close coating of hard conating rapidly if heat or heating, humidification.Therefore, when situation about heating, be preferred in the following heating of heat resisting temperature of base material (between base material and coating during set middle layer, base material and these layers).At this, the heat resisting temperature of so-called base material is exactly the ceiling temperature that in fact can keep substrate property, if the middle layer of plastics, organic class for example is glass temperature and Tc and decomposition point etc.
And, in dried coating film (sclerosis), organo-silicon compound (III) content of the coating composition that forms when being used for filming is during greater than the situation of 3 quality %, this organo-silicon compound (III) evaporation specially, disperse, will influence the performance of security and gained coating (and then gas stop resin formation body), but the coating composition among use the present invention, at base material (when between base material and overlayer, the middle layer being set, base material and these layer) under the following heating state of heat resisting temperature, can prevent the evaporation of organo-silicon compound (III) effectively.Especially, organo-silicon compound (III) are by reaction (condensation) in the system film, effect with the moisture-proof that improves the coating that forms, greatly also can keep sufficient gas barrier property even the humidity in the atmosphere becomes, so can prevent the evaporation of organo-silicon compound (III), be very effective.
Further, after above-mentioned dried coating film (sclerosis), it is preferred carrying out maturation process.By maturation process, reduce and reduced the SiOR in the unreacted above-mentioned organic compound (II) in the coating 3SiOR in group and the organo-silicon compound (III) 2Group, even under any environment for use (for example, in the situation that becomes the inner for the moment high negative pressure state of humid tropical condition, wet condition or liquid crystal etc.), also can bring into play high gas barrier property, be that we are desirable, so maturation process is for after above-mentioned dried coating film (sclerosis), can make the SiOR in the unreacted above-mentioned organic compound (II) in the coating 3SiOR in group and the organo-silicon compound (III) 2Radical reaction (condensation).As maturation process, for example can be used on and reduce unreacted effective thermal treatment in base aspect (for example under 40-60 ℃ of temperature, thermal treatment 1-7 days) and Corona discharge Treatment etc., if can promote the SiOR in the unreacted above-mentioned organic compound (II) in the coating 3SiOR in group and the organo-silicon compound (III) 2Radical reaction (condensation) just should not limit these especially.
And, aspect base material (layer when between base material and coating, the middle layer being set) time of last formation coating and the relation of unreacted base, as long as base material (when between base material and coating, the middle layer being set layer) go up apply add the water decomposition condensation reaction and obtain add the water decomposition condensation product, after dry (sclerosis), and then make SiOR in the unreacted organic compound (II) 3SiOR in group and the organo-silicon compound (III) 2Radical reaction (condensation), handle just, perhaps apply making to go up at base material (when between base material and coating, the middle layer being set layer) before adding the water decomposition condensation reaction, make it simultaneously to add the water decomposition condensation reaction with dry (sclerosis), and then make SiOR in the unreacted above-mentioned organic compound (II) 3SiOR in group and the organo-silicon compound (III) 2Radical reaction (condensation) is handled just, or the like, should not limit especially.
By above-mentioned drying of filming (sclerosis), further, just can on base material, form the coating that obtains by coating composition of the present invention by maturation process.
The thickness of above-mentioned coating, according to the difference of use and difference, therefore can not unify regulation, as long as can satisfy the performance requirement of gas barrier property as effect of the present invention, adaptation, the transparency, subduing property, printing, moisture-proof etc. effectively with base material, usually at 0.01-20 μ m, preferred 0.1-15 μ m, more preferably 0.5-10 mu m range.When (dried) thickness of coating is 0.01 μ m situation, except easily generation pinprick on the coating, coating is also inhomogeneous, is difficult to the performance requirement of fully satisfied gas barrier property as effect of the present invention, the adaptation with base material, the transparency, subduing property, printing, moisture-proof etc. simultaneously.On the other hand, during greater than 20 μ m situations, coating generation crackle is not so be desirable at (dried) thickness of coating.
In addition, as the base material that can be used in gas stop resin formation body of the present invention, if having thermotolerance, subduing property, the transparency, moisture-proof, solvent resistance etc. to the desired characteristic of substrate, just should not limit especially.Can use the base material of the various uses of the gas barrier property that requires, for example be used for base material of the container of the container of base material, food and drink product of the liquid crystal display substrate of LCD (panel) and other base plate for displaying and wrappage (food packing film and packaging film etc.), pharmaceuticals and medicine equipment and wrappage etc. etc.Particularly, for each such purposes, the desired characteristic of base material is required also different, so can not unify regulation, should be according to characteristic requirement separately, for example according to mechanical property, optical characteristics etc., the only base material of suitable selection is not particularly limited.If give an example particularly, can enumerate tygon, polyolefin resins such as polypropylene, polyethylene terephthalate, polyethylene glycol isophthalate, poly-2,6 naphthalenedicarboxylic acids (Na Off レ one ト) glycol ester, polybutylene terephthalate, and the polyester resin of their multipolymer etc., polyamide-based, polystyrene, polymethacrylate, polyacrylonitrile, polyvinyl acetate (PVA), polycarbonate, poly-aryl compound, cellophane, polyimide, polyetherimide, polysulfones, polyethersulfone, polyetherketone, ionomer resin, thermoplastic resins such as fluororesin, and melamine resin, urethane resin, epoxy resin, phenolic resin, unsaturated polyester resin, urea resin, alkyd resin, the thermoset resin of silicones etc. etc.Also have, optimum base material is different different because of each purposes as mentioned above, but be used in liquid crystal display substrate and other displays with in the base material, from viewpoints such as thermotolerance, physical strength, the transparency, mouldability, preventing property of reflection, optimum base material optimization polycarbonate, poly-aryl compound etc.Base material in the time of as container that gas stop resin formation body is used for the food and drink product and packing material (food packing film and packing film etc.), from physical strength, the transparency, thermotolerance, the moulding easiness, painted, viewpoints such as low heating power quantification are set out, preferred impact resistant polystyrene (HIPS), polyethylene terephthalate (PET), gas barrier resin, polyolefin resin such as tygon and polypropylene, polyacrylonitrile, polyamide, cellophane, especially from being easy to process viewpoint, more preferably polypropylene, polyamide, thermoplastic resins such as PET.These can independent a kind of use, also can more than two kinds and use.In addition, the characteristic requirement that these substrates can not obtain in order to obtain with homogenous material can make multilayer with the material of different in kind.As mentioned above, these base materials should be the most general but utilize the plastics with transparency for the master, but should not limit these according to the suitable decision of use, do not get rid of translucent or opaque plastics.Further glass, pottery, metal (comprising alloy and metal oxide) etc. also are suitable for, and for example on transparent plastic substrate (a part), vacuum metallizing etc. also belong to technical scope of the present invention.
As the shape of above-mentioned base material, not restriction especially has and can select according to use is suitable according to the feature of arbitrary shape moulding.And, should not adhere rigidly to the title of substrate, for example show occasion with base materials at liquid crystal display substrate and other, if the form that is suitable for just should be included in the scope of the present invention, except that film shape, also can be chip shape.Also have, in the middle of film shape and chip shape, can have curved surface.And the packing material base material occasion at the container of food and drink product and wrappage etc. if be applicable to the form of this purposes, just should be included in the scope of the present invention, and except that film shape, also can be chip shape, bottle shape etc.And, in the middle of film shape and chip shape, can have curved surface.
The thickness of above-mentioned base material, different different because of use, unified regulation is difficult, should select according to purposes is suitable.For example, show with in the base material that thickness is usually at 5-1000 μ m being used in liquid crystal indicator and other, preferred 10-500 μ m, more preferably 100-300 mu m range.When base material thickness is less than 5 μ m,, image bad except that surface smoothing is bad,, can not keep full intensity etc. sometimes, so be unfavorable as surperficial panel.On the other hand, when base material thickness is greater than 1000 μ m, except that the image confusion, is difficult to sometimes satisfy what is called is carried the requirement of the desired light weight slimming of apparatus, so be unfavorable.In addition, in the packing material base material of container that is used in the food and drink product and wrappage (food packing film and packing film etc.) etc., thickness is usually at 7-100 μ m, more preferably at the 10-30 mu m range.When the thickness of this base material less than 7 μ m the time, except that pinprick may take place, physical strength was also good inadequately, so be not desirable.On the other hand, when the thickness of this base material the time, except the productivity of gas stop resin formation body is bad, be difficult to sometimes satisfy to container and the desired filming requirement of wrappage, so be unfavorable greater than 100 μ m.
In addition, in the middle of the gas stop resin formation body in the present invention, between base material and coating, perhaps on coating, as required, other layers can be set.For example,, further form known in the past various gas barrier resin compositions as the gas barrier property coat, can be multilayer structured.Below, describe as an example with the gas barrier resin coat.For between above-mentioned base material and coating, perhaps on coating, form such gas barrier resin coat, particularly, in order to be easy to even film forming, may utilize by gas barrier resin being dissolved in appropriate solvent and spreading agent and even disperseing and the composition that forms, for example may utilize composition that can form and the composition that forms by making gas barrier resin emulsification etc. in water and solvent by gas barrier resin is dissolved.As gas barrier resin, for example can enumerate polyvinyl alcohol (PVA), ethylene-vinyl alcohol copolymer, Vingon, polyamide etc.Refer to as the gas barrier property tree, preferably polyethylene alcohol, ethylene-vinyl alcohol copolymer, this material is not except containing the chlorine that can become the public hazards reason, even under any environment for use (for example, in the situation that becomes the inner for the moment high negative pressure state of humid tropical condition, wet condition or liquid crystal etc.), also can bring into play fully high gas barrier property, be comparatively effective, and we are desirable so can be described as.That is to say, we can say because such gas barrier resin coat can be found the good gas barrier property that known gas barrier layer had in the past for the present invention.Therefore, in the present invention, because above-mentioned coating has the abundant gas barrier property that can not obtain in the known in the past gas barrier layer, and the gas barrier property that has in humid tropical condition, wet condition or liquid crystal inside more the situation etc. of for the moment high negative pressure state, so obtain having the laminated body of very high performance gas barrier property.
In the said gas-blocking resin coating layer, except the said gas-blocking resin, also can in the scope of not damaging effect of the present invention, cooperate the various adjuvants of inorganic organic class such as curing catalysts, wettability improver, plastifier, defoamer, tackifier as required.About its use level,, and in can bringing into play the scope of the characteristic of adjuvant separately effectively, just should not limit especially if do not damaging in the scope of the invention.
The thickness of gas barrier resin coat of the present invention, different and different because of laminated layer sequence with purposes, therefore can not unify regulation, but usually at 0.3-20 μ m, preferred 0.5-10 μ m is more preferably in the 1-5 mu m range.When the thickness of gas barrier resin coat less than 0.3 μ m the time, the functions such as gas barrier property of having added the gas barrier resin coat are insufficient.On the other hand, when greater than 20 μ m the time, the productivity of gas barrier resin coat is bad.
In addition, in gas stop resin formation body of the present invention, multilayer thermoplastic film further.Owing to use this multilayer thermoplastic film, good more high-strength hot sealing, the gas stop resin formation body of security can be provided.Also have, thermoplastic film generally is used as the top overlay in the lamination gas stop resin formation body, but also can be according to use, in gas barrier laminate as the middle layer lamination.
As above-mentioned thermoplastic film, if can satisfy, just should not limit especially according to the desired characteristic requirement of use, can utilize known in the past film, consider optimization polypropylene, tygon from security, cost aspect.
Gas stop resin formation body of the present invention is by forming coating on above-mentioned base material, further as required, forms that the gas barrier resin coat constitutes.Because described formation, compare with already present gas-barrier films substrate, can further give function, but said here so-called function is different different because of use, so be not particularly limited, but for example can enumerate the environmental safety of heat seal, chemical-resistant, gas barrier property etc.Specifically, even under any damp condition, can both obtain the stable gas stop resin formation body of gas barrier property.
In addition, the gas stop resin formation body among the present invention, as long as at the above-mentioned at least coating of base material superimposed layer, further lamination gas barrier resin coat is just as required.In addition; except that above-mentioned coating and gas barrier resin coat; the coat that also can have other characteristics; transparency electrode (ITO etc.) layer for example; the common electrode layer; polarizing layer; antireflection layer; the orientation rete; the phasic difference layer; sheathcoat; color filter layers; the TFT layer; dielectric layer; protective film; fluorophor; insulation course; resistant layer; barrier film; protective film; cold cathode; ゲ one ト; negative electrode; anode; the instantaneous short burst line of anode (ァ ノ one De バ ス line); show electrode; address electrode; the aluminium-vapour deposition layer; sticking interlayers etc., lamination or the suitable coat of selecting formation to have other characteristics as required can suit to select to carry out.These coatings and gas barrier resin coat can form or lamination in the inside of formed base material side.And these need only the purposes according to its use, and suitable decision laminated layer sequence and laminated thickness are just.In addition, on these coats, can design the good chemical-resistant coat that is used as top coat in a sense, also can the above-mentioned thermoplastic film of lamination.That is to say, use thermoplastic film, can make it to have the characteristic that requires as the top coat that has existed, and can give heat seal, security, so be outstanding.
That is, in gas stop resin formation body of the present invention, between base material and coating and at the first-class place of coating, also can there be layer with other functions.And, comprise these layers of coating, can not respectively one deck (individual layer), also can be by the sandwich construction that forms of layer more than one deck as required.
With regard to the gas barrier property of gas stop resin formation body of the present invention, therefore different and different because of the structure composition of each layer and all rhythmo structure etc. can not unify regulation.Satisfy formation necessary condition of the present invention but be at least, the oxygen permeability (A) after 60 ℃ of this gas stop resin formation body, 90%Rh were handled in 24 hours can reach the ratio of the oxygen permeability (B) before handling, (A)/(B)≤10.0, and preferred≤5.0.In the ratio (A)/(B)>10.0 of oxygen permeability (A) after 60 ℃ of gas stop resin formation body, 90%Rh were handled in 24 hours to the oxygen permeability (B) before handling, because of the environmental change gas barrier property changes (variation), therefore except not necessarily ensuring the quality of products, can not find in hot and humid sufficient gas barrier property down, so be not desirable.And, the condition when oxygen permeability (A) and measurement (B) be not hot and humid down, as long as under 20-30 ℃ usually, 85-95%Rh condition, measure (with reference to as described later embodiment 1-6 and comparative example 1-6 etc.), so should not limit especially.
In addition, the said gas-blocking resin-formed body, except because of the different desired benchmark differences of use, also different and different because of the kind of base material and the structure of all laminations etc., therefore can not unify regulation, but if for example as the use occasion with film of the container package of Food ﹠ Drink product, gas (oxygen) permeability when wishing under high humidity (20 ℃, 90% Rh) is at 30ml/m 2Below the 24hatm, preferred 20ml/m 2Below the 24hatm, more preferably 10ml/m 2Below the 24hatm.
Further, the same with transparent membrane with the following choke that will illustrate, it is exactly more suitably that the oxygen permeability the when flexible resistance of gas stop resin formation body test 20 times later 20 ℃, 60%Rh satisfies following benchmark requirement: at 20ml/m 2Below the 24hatm, preferred 10ml/m 2Below the 24hatm, more preferably 5ml/m 2Below the 24hatm.
In addition, with regard to the manufacture method of the gas stop resin formation body relevant with the present invention, should not limit especially, the known in the past various display fabrication techniques of suitable utilization, to the thin film fabrication technology on the film substrate, for example by the cylinder cladding process, the immersion coating method, the bar cladding process, the pressing mold cladding process, the integrated molding of spin coating method or base material and gas stop resin formation body (is extruded, compression, injection-molded moulding etc.) technology, coating technique, the forming technique of the container package material of lamination technology etc. etc. and the coating technology or the wet type film technique that make up these method etc., further dry masking technique of physical vapor deposition etc. etc. just can be made.In addition, in the TFT in forming gas stop resin formation body etc., need only manufacturings such as suiting to utilize semiconductor fabrication.
Suitable embodiment as the manufacture method of the gas stop resin formation body relevant with the present invention, it is characterized in that, on base material, coating comprise have amino macromolecular compound (I) and in molecule, have can with the functional group's of amino reaction organic compound (II), further comprise coating composition, make the formation coating by the organo-silicon compound (III) of above-mentioned general formula (1) expression.But in addition, also can form gas barrier resin and cover coating, transparent electrode layer, common electricity layer, polarizing layer, antireflection layer, orientation rete, phasic difference layer, sheathcoat, color filter layers, TFT layer, dielectric layer, protective film, fluorophor, insulation course, resistant layer, barrier film, opposing rete, cold cathode, グ one ト, negative electrode, anode, the instantaneous short burst line of anode (ァ ノ one De バ ス line), show electrode, address electrode, aluminium-vapour deposition layer, adhesive linkage and thermoplastic film etc.In addition, the formation method with regard to each layer should not limit especially, the method for having narrated above can utilizing etc., in this description will be omitted.
Secondly, the purposes of the gas stop resin formation body relevant with the present invention is characterized in that, as liquid crystal display substrate.Thus, even at (from constant temperature and humidity under the dried state and even under the lower negative pressure state under hot and humid wet condition and for the moment liquid crystal inside become the situation etc. of high negative pressure state) under any environment for use, also can give full play to high gas barrier property, solve in the past because the problem of the malfunction that causes because of gas-premeable difference gassing that hot and humid time Exposure to Sunlight causes etc. so can provide, provide to have high-performance and the high liquid crystal display substrate of high-quality reliability, and then use it to form liquid crystal indicator.
