Embodiment
Below, embodiments of the present invention are described.
1. the formation of adhesion zone
Fig. 1 means the figure (the 1st embodiment) of an example of formation of the adhesion zone 1 of applicable present embodiment.The adhesion zone 1 of present embodiment is used in the purposes of making for the plastic lens such as ophthalmic lens etc.
As shown in Figure 1, the adhesion zone 1 of present embodiment has composite base material 2 and the stacked structure of adhesive coating 3.And composite base material 2 is stacked and form by being formed with the 1st duplexer 10 of inorganic thin film layer 5 and being formed with the 2nd duplexer 20 of adhesive linkage 6 on the 1st base material 4 on the 2nd base material 7.In addition, in present embodiment, adhesive coating 3 forms on the face of the 1st base material 4 sides of composite base material 2.
In addition, in the adhesion zone 1 of present embodiment, according to the steam permeability of JIS K7129 (following, to be sometimes only called steam permeability), be 1.5g/ (m
224h).When steam permeability is this scope, in the manufacturing process of plastic lens described later, can suppresses moisture and see through adhesion zone 1 and invade in cavity C (with reference to Fig. 3), can suppress the bubble in plastic lens, the generation of albefaction.
In addition, in the adhesion zone 1 of present embodiment, as required, can between composite base material 2 (the 1st base material 4) and adhesive coating 3, between the 1st base material 4 and inorganic thin film layer 5, be provided for improving the tackifier coating (not shown) of adaptation.
In addition, also can implement to the surface of the 2nd base material 7 (with the face of adhesive linkage 6 opposition sides) surface treatments such as separability improved treatment.
1.1 composite base material
As mentioned above, the composite base material 2 of present embodiment passes through the 1st duplexer 10 and the 2nd duplexer 20 is stacked, thereby has the structure of the 1st base material 4, inorganic thin film layer 5, adhesive linkage 6 and the 2nd base material 7 stacked above one another.
Below, to forming each layer of composite base material 2, describe.
The 1st base material
The material of the 1st base material 4 using in the adhesion zone 1 of present embodiment is not particularly limited, and can use the base material such as plastics, metal system etc.
Wherein, particularly preferably use and take the base material that polyethylene terephthalate (PET) is principal constituent.In addition, as the 1st base material 4, for example, also can use the resin molding of polybutylene terephthalate, PEN, polyphenylene sulfide, biaxial stretch-formed polypropylene, polyimide, aromatic poly amide, poly-cycloolefin, fluorine resin etc.
For detailed content, explanation in the back, on the 1st base material 4 of present embodiment, setting example is as comprised the inorganic thin film layer 5 of silicon, aluminium etc.
Use in the situation of PET as the 1st base material 4, the thickness that preferably makes the 1st base material 4 is the scope below the above 25 μ m of 9 μ m.
The thickness of the 1st base material 4 is less than in the situation of 9 μ m, and on the width of adhesion zone 1, the deviation of the thickness of the 1st base material 4 becomes large, easily produces fold during stacked inorganic thin film layer 5, fractures etc. on the 1st base material 4.And its result is that the existence situation that steam permeability partly raises in adhesion zone 1, exists the plastic lens that uses adhesion zone 1 to manufacture easily to produce the tendency of bubble, albefaction.
In addition, in the manufacturing process of adhesion zone 1 described later, the mode that stacked inorganic thin film layer 5 forms on the 1st base material 4 the 1st duplexer 10 becomes periphery according to inorganic thin film layer 5 sides is conventionally reeled.Here, the thickness of the 1st base material 4 surpasses in the situation of 25 μ m, and the situation below being 25 μ m with the thickness of the 1st base material 4 is compared, and while reeling the 1st duplexer 10, the outer circumferential side (inorganic thin film layer 5 sides) of the 1st duplexer 10 easily extends.Its result is, in the 1st duplexer 10, inorganic thin film layer 5 extends, therefore exist the integral body of inorganic thin film layer 5 the to crack situation of (cracking).And in the adhesion zone 1 of crackle that has produced like this inorganic thin film layer 5, the situation that exists steam permeability to raise, exists the plastic lens that uses adhesion zone 1 to manufacture easily to produce the tendency of bubble, albefaction.
The 2nd base material
The material of the 2nd base material 7 and the 1st base material 4 similarly, are not particularly limited, and for example, can use the base material of plastics, metal system etc.
Wherein, particularly preferably use and take the base material that polyethylene terephthalate is principal constituent.In addition, as the 2nd base material 7, with the 1st base material 4 similarly, for example, also can use the resin molding of polybutylene terephthalate, PEN, polyphenylene sulfide, biaxial stretch-formed polypropylene, polyimide, aromatic poly amide, poly-cycloolefin, fluorine resin etc.
Use in the situation of polyethylene terephthalate as the 2nd base material 7, the thickness that preferably makes the 2nd base material 7 is in the scope below the above 38 μ m of 18 μ m.
In the too small situation of the thickness of the 2nd base material 7, the rigidity of the 2nd base material 7 easily reduces, and in lens described later manufacturing process, has the tendency that is difficult to maintain the interval between 2 moulds 50 (with reference to Fig. 3).In addition, in the too small situation of the thickness of the 2nd base material 7, existence can not resist the power expanding to the resin 100 (with reference to Fig. 3) that injects between the cavity C being formed by mould 50 and adhesion zone 1 completely and cause adhesion zone 1 to produce breaking, cut-out etc., air is invaded the situation in cavity C.Further, in the too small situation of the thickness of the 2nd base material 7, worry can not be resisted the power that resin in cavity C 100 shrinks completely and be caused adhesion zone 1 to produce fold to be pressed against the mode at the center of cavity C and to be stretched, and produces to result from the fold (band fold) of fold of adhesion zone 1 on the lens that form.
On the other hand, in the excessive situation of the thickness of the 2nd base material 7, exist the rigidity of the 2nd base material 7 easily to raise, the tendency that the retractility of adhesion zone 1 declines.In addition, it is large that the total thickness of adhesion zone 1 becomes, and in lens described later manufacturing process, when mould 50 is wound around to adhesion zone 1, at the overlapping lap of adhesion zone 1, exists between adhesion zone 1 and produce gap, the situation that resin 100 spills from cavity C.
In addition, when the relation of the 1st base material 4 and the 2nd base material 7 is considered, the thickness of the 2nd base material 7 is preferably 2 times of above 3 times of following scopes of the thickness of the 1st base material 4.By making the 1st base material 4 and the 2nd base material 7 there is such relation, when coiling adhesion zone 1, in the manufacturing process of plastic lens etc., can suppress to follow adhesion zone 1 distortion and to inorganic thin film layer 5 applying loads that arrange between the 1st base material 4 and the 2nd base material 7.Further, by making the 1st base material 4 and the 2nd base material 7 there is such relation, can make the rigidity of adhesion zone 1 integral body and retractility in the preferred scope of moulding purposes as plastic lens.Thus, the generation that in the manufacturing process of plastic lens described later, can suppress that moisture is sneaked in cavity C, resin 100 spills etc. from cavity C.
Further, in addition, the aggregate thickness of the 1st base material 4 and the 2nd base material 7 merging is preferably to the scope below the above 60 μ m of 27 μ m.By making the aggregate thickness of the 1st base material 4 and the 2nd base material 7 merging, it is such scope, in the manufacturing process of plastic lens described later, can suppress to be leaked by the poor liquid causing of section of the overlapping lap of adhesion zone 1, can suppress owing to following the distortion of the contraction etc. of resin 100 (with reference to Fig. 3) to cause adhesion zone 1 damaged or peel off simultaneously.
Inorganic thin film layer
Inorganic thin film layer 5 contains inorganic substance and forms, and is in order to improve moisture resistance and the gas barrier property of adhesion zone 1, suppresses moisture in adhesion zone 1 and sees through and arrange.
As the inorganic substance that form inorganic thin film layer 5, can enumerate silicon, aluminium, magnesium, zinc, tin, nickel, titanium, hydrocarbon polymer etc., or their oxide compound, carbide, nitride or their mixture.Wherein, the material that preferably adopt Si oxide, silicon nitride, aluminum oxide, aln precipitation, the hydrocarbon polymer of diamond-like carbon etc. of take is main body.Especially, as inorganic thin film layer 5, silicon-dioxide, aluminum oxide are more preferably used in the aspect seeing through from the moisture that can suppress adhesion zone 1.
In addition, above-mentioned inorganic substance can be used separately a kind, also can combine two or more and use.
As the formation method of inorganic thin film layer 5, can use the known methods such as vapour deposition method, coating method.Wherein, from obtaining, moisture resistance and gas barrier property are high, the aspect of uniform film, preferably adopt vapour deposition method.Vapour deposition method comprises the methods such as PVD (physical vapor vapour deposition method), CVD (chemical vapor coating method) that comprise vacuum evaporation, ion plating, sputter etc.
The thickness of inorganic thin film layer 5 is for example the scope of 0.1nm～500nm, is preferably the scope of 0.5nm～40nm.By making the thickness of inorganic thin film layer 5, be above-mentioned scope, can suppress seeing through of moisture, in addition, the generation that can suppress to break in inorganic thin film layer 5 etc.In addition, by making the thickness of inorganic thin film layer 5, be above-mentioned scope, can suppress the transparent decline of adhesion zone 1.
Adhesive linkage
As the thickness of adhesive linkage 6, be preferably the scope below the above 10 μ m of 1 μ m.
In the too small situation of the thickness of adhesive linkage 6, there is the inadequate tendency of bonding strength of adhesive linkage 6 and inorganic thin film layer 5.And, in situation about declining with the bonding strength of inorganic thin film layer 5, can produce breaking of inorganic thin film layer 5, the steam permeability of adhesion zone 1 easily raises.
On the other hand, in the excessive situation of the thickness of adhesive linkage 6, the easy thickening of total thickness of adhesion zone 1.And, in the situation of the total thickness thickening of adhesion zone 1, in the manufacturing process of plastic lens described later, when mould 50 is wound around to adhesion zone 1, at the overlapping lap of adhesion zone 1, exists between adhesion zone 1 and produce gap, the situation that resin 100 spills from cavity C.
1.2 adhesive coating
The adhesive coating 3 of present embodiment is formed by tackiness agent.The tackiness agent that forms adhesive coating 3 is for example by take the organosilicon tackiness agent of addition reaction-type, the organosilicon tackiness agent of peroxide curing type and be principal constituent to the effective linking agent of organosilicon tackiness agent of addition reaction-type material forms.
Organosilicon tackiness agent as addition reaction-type, for example, can enumerate KR3700, KR3701, X-40-3237-1, X-40-3240, X-40-3291-1, X-40-3229, X-40-3270, the X-40-3306 of Shin-Etsu Chemial Co., Ltd's system, TSR1512, TSR1516, the XR37-B9204 of Momentive Performance Materials company system, SD4584, SD4585, SD4560, SD4570, SD4600PFC, the SD4593 etc. of Dong Li DOW CORNING Co., Ltd. system, but be not particularly limited to this.
In addition, organosilicon tackiness agent as peroxide curing type, for example, can enumerate KR100, the KR101-10 of Shin-Etsu Chemial Co., Ltd's system, YR3340, YR3286, PSA610-SM, the XR37-B6722 of Momentive Performance Materials company system, the SH4280 of Dong Li DOW CORNING Co., Ltd. system etc., but be not particularly limited to this.
In addition, linking agent as addition reaction-type organosilicon caking agent, for example, can enumerate X-92-122, the CR50 of Momentive Performance Materials company system of Shin-Etsu Chemial Co., Ltd's system, the BY24-741 of Dong Li DOW CORNING Co., Ltd. system etc., but be not particularly limited to this.
By forming such formation, adhesive coating 3 can, in the manufacturing process of plastic lens described later, be given full play to the clinging power to mould 50 (with reference to Fig. 3) near normal temperature.Thus, can suppress resin 100 (with reference to Fig. 3) and spill from mould 50, can suppress the bubble in plastic lens, the generation of defect.In addition, by making adhesive coating 3 have above-mentioned formation, under the high-temperature atmosphere of polymerization of following resin 100, the cohesive force of adhesive coating 3 dies down, and the power that acts on the width of adhesion zone 1 dies down.Thus, adhesion zone 1 can be followed the distortion of the resin 100 of following polymerization and shrinking and is out of shape, and can suppress because forming defect, the bubble that space produces in plastic lens between adhesion zone 1 and resin 100.
As the ratio that forms each integrant of adhesive coating 3, the organosilicon tackiness agent of preferred addition reaction-type is that the organosilicon tackiness agent of 95 mass parts～65 mass parts, peroxide curing type is 5 mass parts～35 mass parts, to the effective linking agent of organosilicon tackiness agent of addition reaction-type, is the scope of 0.1 mass parts～0.2 mass parts.
For example, in the situation that the organosilicon tackiness agent of addition reaction-type organosilicon tackiness agent very few, peroxide curing type is too much, there is the tendency of the clinging power decline of adhesion zone 1.And, in the situation that the clinging power of adhesion zone 1 declines, in the manufacturing process of plastic lens described later, exist adhesion zone 1 easily from mould 50 (with reference to Fig. 3), to peel off, produce the situation of the liquid leakage of resin 100 (with reference to Fig. 3).And, in the situation that produced the liquid of resin 100, leak, exist the plastic lens forming to produce the situation of defect.
In addition, in the situation that the organosilicon caking agent of addition reaction-type organosilicon tackiness agent too much, peroxide curing type is very few, there is the tendency of the clinging power increase of adhesion zone 1.And in the manufacturing process of plastic lens, in the situation that resin 100 shrinks, adhesion zone 1 cannot be followed the contraction of resin 100, exists between adhesion zone 1 and resin 100 and forms gap, produces the situation of bubble in the plastic lens forming.
Further, in the situation that the effective linking agent of organosilicon tackiness agent of addition reaction-type is less than to 0.1 mass parts, the clinging power of the adhesion zone 1 under the environment below 50 ℃ declines, in the situation that resin 100 expands in the manufacturing process of plastic lens, there is the situation of the liquid leakage that produces resin 100.
In addition, in the situation of linking agent more than 0.2 mass parts, when resin 100 polymerization, exist adhesion zone 1 cannot follow the contraction of resin 100, between resin 100 and adhesion zone 1, form space, in plastic lens, produce the situation of bubble.Further, in the plastic lens forming, the thickness of central part (CT) produces deviation with the thickness (ET) of end, and existence cannot form the situation of the plastic lens with desired thickness.
In addition, in the adhesion zone 1 of present embodiment, make the organosilicon tackiness agent that adhesive coating 3 contains addition reaction-type, organosilicon tackiness agent and the effective linking agent of organosilicon tackiness agent to addition reaction-type of peroxide curing type, but the formation of adhesive coating 3 is not limited to this, also can form adhesive coating 3 with other tackiness agents.
In addition, in the adhesion zone 1 of present embodiment, in composite base material 2, adhesive coating 3 is arranged on to the 1st base material 4 sides of the 1st duplexer 10, but also adhesive coating 3 can be arranged on to the 2nd base material 7 sides of the 2nd duplexer 20.But, from the manufacturing process at adhesion zone 1, suppress breaking of inorganic thin film layer 5 etc., suppress the viewpoint of rising of the steam permeability of adhesion zone 1, preferably adhesive coating 3 is arranged on to the 1st base material 4 sides.
Fig. 2 means the figure of an example of the 2nd embodiment of the adhesion zone of applicable present embodiment.The formation same with Fig. 1 used to identical symbol, and description is omitted.
As shown in Figure 2, the adhesion zone 11 of applicable present embodiment is laminated by composite base material 2 and adhesive coating 3.Composite base material 2 consists of the 2nd duplexer 20 that is formed with the 1st duplexer 10 of inorganic thin film layer 5 and is formed with adhesive linkage 6 on the 1st base material 4 on the 2nd base material 7.And the 1st duplexer 10 is stacked according to the inorganic thin film layer of the 1st duplexer 10 5 mode relative with the adhesive linkage 6 of the 2nd duplexer 20 with the 2nd duplexer 20.Further, in present embodiment, the 2nd base material 7 of the 2nd duplexer 20, with the face of adhesive linkage 6 opposition sides on be formed with adhesive coating 3.
2. the manufacture method of adhesion zone
Next, enumerate the adhesion zone 1 of applicable the 1st embodiment illustrated in fig. 1 for example, its manufacture method is described.Adhesion zone 1 passes through to form composite base material 2, and the stacked adhesive coating 3 of composite base material 2 forming is formed.
The formation of composite base material
First, as on the PET film of the 2nd base material 7, for example, use the caking agent that the coatings such as gravure roll consist of polyester urethane caking agent, epoxy resin adhesive etc. to be also dried.Thus, be formed on the 2nd duplexer 20 that is laminated with adhesive linkage 6 on the 2nd base material 7.
Next, for the 2nd duplexer 20 forming, according to inorganic thin film layer 5 mode relative with adhesive linkage 6, be fitted in and be used as the 1st duplexer 10 that is laminated with the inorganic thin film layer 5 being formed by silicon-dioxide etc. on the PET film of the 1st base material 4.Thus, form the composite base material 2 that the 1st duplexer 10 and the 2nd duplexer 20 are laminated.
Afterwards, according to the 1st duplexer 10 sides (the 1st base material 4 sides), be the mode of inner side, coiling composite base material 2, by the composite base material 2 of reeling under 40 ℃～50 ℃ atmosphere aging 48 hours.
But, in the formation operation of composite base material 2, for example, in the situation that forming adhesive linkage 6 by the stacked direct coating adhesive of inorganic thin film layer 5 on to the 1st base material 4 and thereby stacked the 2nd base material 7 forms composite base material 2 on this adhesive linkage 6, exist inorganic thin film layer 5 to produce to break, the situation of be full of cracks etc.
Particularly, on the adhesive linkage 6 forming during coating adhesive, on inorganic thin film layer 5 on inorganic thin film layer 5 further during stacked the 2nd base material 7 etc., likely inorganic thin film layer 5 applying loads are caused inorganic thin film layer 5 to produce breaking, be full of cracks etc.And, in the adhesion zone 1 that comprises such inorganic thin film layer 5, when inorganic thin film layer 5 breaks etc., exist moisture easily to see through, the worry that steam permeability rises.
On the other hand, in present embodiment, adhesive linkage 6 is not directly layered on inorganic thin film layer 5, but adhesive linkage 6 is layered on the 2nd base material 7 and forms after the 2nd duplexer 20, the 1st duplexer 10 and the 2nd duplexer 20 are fitted, thereby formed composite base material 2.By utilizing such operation to form composite base material 2, in the present embodiment, compare with the situation that directly forms as mentioned above adhesive linkage 6 on inorganic thin film layer 5, can suppress inorganic thin film layer 5 applying loads.Its result is, can suppress the generation of breaking, chapping of inorganic thin film layer 5, can suppress the rising of the steam permeability of adhesion zone 1.
The formation of adhesive coating
Next, for completing aging composite base material 2, the tackiness agent that coating consists of silicone resin etc. on the 1st base material 4 of the 1st duplexer 10, forms adhesive coating 3.
Particularly, the organosilicon tackiness agent of the organosilicon tackiness agent such as addition reaction-type and peroxide curing type is being dissolved in the solution of the organic solvent gained such as toluene, dimethylbenzene, is adding the effective linking agent of organosilicon tackiness agent of addition reaction-type is made to adhesion agent composition.Then, use comma coating machine, die lip coating machine etc., the 1st base material 4 these adhesion agent compositions of coating according to the mode of dried even thickness to composite base material 2.Afterwards, under specified temperature, make the adhesion agent composition of coating dry, thereby on composite base material 2, form adhesive coating 3.
By above operation, can obtain the adhesion zone 1 shown in Fig. 1 (the 1st embodiment).
Conventionally, the in the situation that of making adhesion zone using comma coating machine, die lip coating machine etc. to form adhesive coating to base material, while base material is applied to the coating that tension force carries out adhesion agent composition.Here, in the situation that be formed with for example such film with inorganic substance of inorganic thin film layer 5 of present embodiment on base material, while forming adhesive coating on base material, by base material is applied to tension force, or film contacts with deflector roll, thereby exist film applying load, film produces the situation of breaking etc.And film has produced in the situation of breaking etc., moisture easily sees through by breaking of film etc., thus the situation that exists the steam permeability of adhesion zone to rise.
On the other hand, the composite base material 2 of the adhesion zone 1 of present embodiment has the forming by the 1st base material 4 and the 2nd base material 7 clamping inorganic thin film layers 5 across adhesive linkage 6.Thus; composite base material 2 is formed in the situation of adhesive coating 3, even in the situation that composite base material 2 has been applied to tension force, compare with the situation without this formation; also can protect inorganic thin film layer 5 by the 1st base material 4 and the 2nd base material 7, can suppress that inorganic thin film layer 5 generations are broken etc.And, by suppressing the generation of breaking of inorganic thin film layer 5 etc., can suppress the rising of the steam permeability of adhesion zone 1.
In addition, the adhesion zone 1 being formed by above-mentioned operation is reeled for the mode of inner side according to adhesive coating 3 conventionally.In present embodiment, owing to being provided with adhesive coating 3 on the 1st base material 4, therefore, under the state of coiling adhesion zone 1, the mode that composite base material 2 is inner side according to the 1st base material 4 sides is reeled.In addition, in the formation operation of above-mentioned composite base material 2, during aging the 1st duplexer 10, the mode that is inner side according to the 1st base material 4 sides the 1st duplexer 10 of reeling.
; in present embodiment; under the state of in the state that the adhesion zone of manufacturing 1 is reeled and the formation operation at composite base material 2, the 1st duplexer 10 being reeled; the coiling direction of the 1st duplexer 10 is identical, and the coiling direction that is arranged at the inorganic thin film layer 5 on the 1st duplexer 10 in the manufacturing process of adhesion zone 1 can not change.
Here, in the situation that for example in the manufacturing process of adhesion zone 1 coiling direction of inorganic thin film layer 5 change, exist inorganic thin film layer 5 applying loads are cracked, defect, the worry of breaking.
On the other hand, in present embodiment, by adopting the formation of the coiling direction variation that does not make inorganic thin film layer 5 in the manufacturing process of adhesion zone 1, can suppress the load to inorganic thin film layer 5, suppress that inorganic thin film layer 5 generations are broken etc.
