Description

The forming method of plastic lens molding adhesive tape and plastic lens molding product
Technical field
The present invention relates in manufacture and the final products tool as plastic lens such as plastic ophthalmic len, optics lens When having the standard forming product of same thickness and curvature used plastic lens molding adhesive tape and plastic lens into Type method.
Background technology
Manufacture method as pervious plastic lens, it is known that used by using a pair of of glass mold (model) and sealing Adhesive tape injected polymeric method and molding method (referring for example to patent document 1 and patent document 2).In the method, will A pair of of glass mold is oppositely disposed across predetermined distance.Then, adhesive tape is circumferentially pasted onto to a pair of of glass mold Outer circumferential surface whole circumference, make polymerization unit.Thus, the adhesive band sealing in space between glass mold.Then, will set The nozzle of fat injection is inserted into the adhesive tape, and the resin (polymerizable monomer) of liquid is injected into the space between glass mold and is filled out Fill.Afterwards, cure the resin polymerization by heating, light irradiation etc., so as to obtain plastic lens molding product.
In the shaping of resin (polymerizable monomer), rise with the temperature of resin, produce thermal expansion, volume increase first (expansion).At this moment, the adhesive tape as sealing, if being more than the adhesive tape of required cohesiveness using the cohesiveness of sticker, The volumetric expansion of the resin cannot be then followed, gap, hair are produced in the part of the bonding plane of adhesive tape and mould, overlap joint adhesive tape Resiniferous liquid leakage.Therefore, molding lens are possible to produce notch.Therefore, as described above, having used cohesiveness more than required The adhesive tape of cohesiveness is not suitable for the manufacture of standard forming product as the forming method of the plastic lens of the adhesive tape of sealing.Specially Sharp document 2,3 proposes the technology of the generations such as the notch for suppressing plastic lens as described above, gonorrhoea, bubble.However, at these In technology, according to the species of the resin (polymerizable monomer) of lens, lens condition of molding, sometimes as sticker and cause Notch caused by the liquid leakage of resin cannot be adequately suppressed produces.
Polymerizing curable starts if the temperature for further increasing the resin, at this moment causes volume to contract due to cure shrinkage It is small.At this moment, the adhesive tape as sealing, if being less than the adhesive tape of required cohesiveness using the cohesiveness of sticker, such as Shown in Fig. 4, the adhering agent layer (illustration omitted) of adhesive tape 100 cannot be sufficiently secured within the outer circumferential surface of mould 30, and mould 30 is being set The shrinkage direction of fat produces deviation.Therefore, it is narrow when the interval of a pair of of mould 30 becomes to inject than resin.Therefore, molding lens Thickness be possible to can (thickness change (thickening)) thinner than desired thickness.As described above, it is required solidifying to have used cohesiveness to be less than The adhesive tape of poly- power is not suitable for the manufacture of standard forming product as the forming method of the plastic lens of the adhesive tape of sealing.From this The reasons why sample, considers, in the forming method of above-mentioned plastic lens, the influence of the characteristic of the sticker of the adhesive tape used is big, Wherein be difficult to yield rate it is excellent and stably manufacture with as the final of the plastic lens such as plastic ophthalmic len, optics lens Product has the standard forming product of same thickness and curvature.
In addition, after the curing reaction of resin, polymerization is cooled to 20 DEG C~50 DEG C or so with unit, is unloaded from mould 30 The plastic lens of lower products formed.At this moment, if the cohesiveness of the adhesive tape in the temperature province is less than required cohesiveness, have The adaptation rise of possible adhesive tape and mould, the sticker of adhesive tape produce residue glue, it is necessary to the mould that will be used on mould It is additionally carried out cleaning, regenerated treatment process.From it is such the reasons why consider, according to the species of mould, lens condition of molding, sometimes It can cause the generation of residue glue that cannot be adequately suppressed on mould because of sticker.
On the sticker of plastic lens molding adhesive tape as described above, due to requiring flexibility, excellent resistance to molten Agent, therefore compared with acrylic acid series sticker, rubber series sticker, majority uses silicon-type sticker.The silicon-type Sticker is roughly divided into 2 kinds according to curing mechanism.1 kind therein is by using freedom of the organic peroxide as curing agent Base reacts and carries out cured silicon-type sticker, and in addition a kind is with being directly connected to by the alkenyl of polysiloxane glue The addition reaction between hydrogen on the silicon atom of poly- organohydrogensiloxanes (crosslinking agent) and carry out cured silicon-type adhesion Agent.
In radical reaction type organosilicon sticker (peroxide reactions type organosilicon sticker), by being used as to this The amount of the organic peroxide of effective curing agent is reacted to adjust crosslink density, but for the yield of the free radical, The main reason for interdependence of atmosphere temperature is big, it is unstable, it is difficult to stably obtain desired crosslink density.The opposing party Face, in addition reaction-type organosilicon sticker, crosslink density is adjusted by the amount of crosslinking agent, but due to radical reaction Slow compared to reaction speed, therefore, the content of alkenyl causes crosslink density greatly to change, and is possible to as time went on Crosslink density is caused to increase, it is difficult to stably obtain desired crosslink density.
In addition, the sticker as plastic lens molding adhesive tape, in usually used silicon-type sticker, contains There is low-molecular-weight siloxane (ring-type of main 3~20 aggressiveness or the dimethyl polysiloxane of straight-chain) to be used as impurity, but by When in lens monomer resin polymerization, these impurity are mixed into resin from adhering agent layer dissolution, therefore former, it is possible to The inside of plastic lens after curing and periphery edge produce gonorrhoea as described above.
As described above, be to provide precisely to be molded in purpose has with the final products as plastic lens The standard forming product of same thickness and curvature, further, can suppress the notch, white of the outer circumferential surface of molding standard forming product Change, the remaining generation of sticker on mould, and even if the plastic lens molding that also can be stably used after long-term keeping In the case of with the forming method of adhesive tape and plastic lens, on yield rate it is excellent, for obtaining the silicon-type of non-defective unit The suitable design of sticker, forming method, situation are not illustrate fully, study so far.

As the embodiment for suppressing residue glue generation, adhering agent layer 3 must have the following conditions：After polymerization cools down, protect Hold the adhering agent layer 3 does not have the state of residue glue on mould 30, specifically, is being glued according to JISZ0237 (ISO29862) Adhesion strength when junctor is glass plate is preferably below 6.0N/10mm.This is because if the adhesion strength of glass plate is exceeded 6.0N/10mm, then the adaptation of adhering agent layer 3 and mould 30 exceed adhering agent layer 3 cohesiveness, be possible to destroy as a result The cohesion of adhering agent layer 3, occurs residue glue on mould 30.
7.2.6. adhesive tape comes off
The embodiment to come off as suppression adhesive tape, it is viscous when adherend is glass plate on above-mentioned adhering agent layer 3 Put forth effort preferably more than 2.0N/10mm.This is because if being less than 2.0N/10mm to the adhesion strength of the glass plate, cannot chase after With the thermal stress (expansion, shrink) of the monomer resin of lens, adhesive tape can come off from mould, it is possible to be unable to molded lens.
7.2.7. thickness change
As the embodiment for suppressing thickness change, adhering agent layer 3 must have the following conditions：Start temperature in polymerisation Keep making the outer circumferential surface of mould be maintained at the state on adhering agent layer surface during the cure shrinkage of polymerizable monomer more than degree, specifically Say that it is 50 points that must make in the retentivity measure at 70 DEG C according to JISZ0237 (ISO29862) until the time fallen in ground It is more than clock.This is because in the case where 70 DEG C of retentivities of adhering agent layer 3 are less than 50 minutes, due to the monomer tree to lens The fixed force deficiency of the cure shrinkage of fat, the distance between mould produce deviation, and it is therefore possible to make the thickness of the lens after shaping Change.
Therefore, in order to suppress the notch of lens, residue glue and the generation of thickness change, adhering agent layer 3 at least must be by 70 Retentivity lowering time at DEG C is set to 50~500 minutes and it is necessary to will be set to 2.0~6.0N/ to the adhesion strength of glass plate 10mm。
7.2.8. albefaction
In addition, for sticker, in the drying, curing process process in sticker, preferably for example by 160 DEG C of progress ~200 DEG C of high-temperature heat treatment, so that the total amount of the low molecular weight polyorganosiloxane of 3~10 aggressiveness in sticker 1g is 165 μ g/g Below or the total amounts of low molecular weight polyorganosiloxane of 3~20 aggressiveness is set to be below 4850 μ g/g.In the low molecule silica of 3~10 aggressiveness The total amount of alkane more than the total amount of 165 μ g/g or the low molecular weight polyorganosiloxane of 3~20 aggressiveness more than 4850 μ g/g in the case of, as As a result it is possible to produce albefaction in lens neighboring.It is preferred that 3~10 aggressiveness, the low molecular weight polyorganosiloxane of 3~20 aggressiveness are few, further Most preferably the low molecular weight polyorganosiloxane of 3~10 aggressiveness is 0 μ g/g.It is not particularly limited on heat treatment temperature, but it is excellent as target It is selected at 160~200 DEG C and is heat-treated.If carrying out long heat treatment at a temperature of more than 200 DEG C, there is cut-out to gather The main chain of organosiloxane, the possibility for increasing low molecular weight polyorganosiloxane, if be heat-treated at a temperature of less than 160 DEG C, Then since temperature is too low, low molecular weight compositions are difficult to evaporate, and residual quantitative change is more, thus is possible to as a result in lens neighboring Albefaction is produced, therefore, it is necessary to pay attention to while suitably adjusting heat treatment condition (temperature, time).
7.2.9. stability
In order to make the high sticker of the tracing ability as adhering agent layer 3, it is necessary to make the cohesiveness of sticker in itself small.Make For this method, have reduce crosslinking agent of the addition in sticker, catalyst amount method, but in the method, sticker Easily the amount be subject to the reactive group in sticker, atmosphere temperature are influenced crosslink density, it is difficult to stably obtain desired holding Power, and in the slow addition reaction-type organosilicon sticker of reaction speed, it will be apparent that find because of long-time preservation and retentivity Increase, it is impossible to fully eliminate undesirable condition as the bad stability of sticker.In order to improve the stability, and make The high sticker of the tracing ability as above-mentioned adhesion coating, such as method can be listed below：Reduce in silicon-type sticker entirety Alkenyl quantity method, i.e., reduce the side of crosslink density by adding the organosilicon sticker without alkenyl of ormal weight Method, though and will be low molecular weight have 3-dimensional cross-linked structure organic siliconresin (MQ resins) content reduce, make organosilicon It is that the loss tangent (tan δ) of the dynamic viscoelastic of sticker entirety is moved to low temperature side, so that method for reducing retentivity etc., But it is not particularly limited in these methods.
The method of the quantity of alkenyl in silicon-type sticker entirety is reduced, i.e., be free of alkene by add ormal weight The organosilicon sticker of base is reduced in the method for crosslink density, and adhering agent layer 3 is preferably at least by according to containing the organic of alkenyl Silicon sticker is 50~70 parts by weight, the organosilicon sticker without alkenyl is 30~50 parts by weight and crosslinking agent and catalysis Agent is formed relative to the organosilicon sticker containing alkenyl for the sticker that the mode of 0.5~1.5 parts by weight coordinates.
If the content of the organosilicon sticker without alkenyl is less than 30 parts by weight, retentivity increase, it is impossible in satisfaction Characteristic is stated, is possible to produce lens notch as a result.In addition, if the content of the organosilicon sticker without alkenyl is more than 50 Parts by weight, then retentivity reduction, it is impossible to meet above-mentioned characteristic, be possible to produce residue glue, the thickness of lens of sticker as a result Degree change.On the other hand, if the organosilicon sticker containing alkenyl is less than 50 parts by weight, retentivity reduces, it is impossible to meets Above-mentioned characteristic, is possible to produce as a result residue glue, the thickness change of lens of sticker.In addition, if having containing alkenyl The content of machine silicon sticker is more than 70 parts by weight, then retentivity increases, it is impossible to meets above-mentioned characteristic, is possible to produce as a result Raw lens notch.Further, if the additive amount of crosslinking agent and catalyst is more than 1.5 parts by weight, unreacted low molecule into Divide the dissolution from resin, there is the possibility for causing albefaction.In addition, in the case where the additive amount of crosslinking agent is less than 0.5 parts by weight, The quantity of reactive group in sticker can cause retentivity significantly to change, while be possible to the time and retentivity generation Change.
Though in addition, by for low molecular weight but with 3-dimensional cross-linked structure organic siliconresin (MQ resins) content reduce, The loss tangent (tan δ) of the dynamic viscoelastic of silicon-type sticker entirety is set to be moved to low temperature side, so as to reduce retentivity In the case of, preferably by according in above-mentioned organosilicon sticker (the organosilicon sticker containing alkenyl and the organosilicon without alkenyl The mixture of sticker) in the composition of polysiloxane glue (G) and organic siliconresin (R) compare for polysiloxane glue 36~ The sticker that 44 parts by weight, the mode of 56~64 parts by weight of organic siliconresin coordinate is formed.
If the ratio of the organic siliconresin in the organosilicon sticker is less than 56 parts by weight, retentivity, adhesion strength drop It is low, it is impossible to meet above-mentioned characteristic, be possible to as a result produce adhesive tape come off, the thickness change of lens.In addition, if organosilicon The ratio of resin is more than 64 parts by weight, then retentivity, adhesion strength increase, it is impossible to meet above-mentioned characteristic, be possible to produce as a result Residue glue, the lens notch of raw sticker.This is because the tracing ability of the thermal expansion to the monomer resin of lens is poor, in adhesive tape 1 Bonding plane, 1 mutual overlap of adhesive tape with mould 30 produce gap, the liquid leakage of resin occur, lens have as a result There may be notch.
By using the organosilicon sticker so adjusted, lens notch, thickness change when being not in lens shaping, The problems such as residue glue, and the change of retentivity can be suppressed, stable sticker can be obtained.
Fig. 3 is represented in the molding procedure of plastic lens molding product, and the bonding force of adhesive tape 1, caused by polymerisation Lens monomer resin temperature change and resin volume change relation figure.
Solid line represents the monomer resin temperature of lens in Fig. 3.The resin temperature is room temperature before polymerisation, but poly- Closing when reaction starts due to its reaction heat causes the temperature of resin slowly to rise, at the end of polymerisation its reaction heat disappear and The temperature of resin is set slowly to be reduced to room temperature.The maximum temperature of resin as caused by the polymerisation is according to the temperature of surrounding, tree The species of fat and it is different, usually most is 120 DEG C~130 DEG C or so.In addition, polymerisation start temperature is according to used The species of the monomer resin of mirror and it is different, it is but in the present invention, so-called to be less than polymerisation start temperature, usually represent 40~70 DEG C temperature range, more than so-called polymerisation start temperature, usually represent 60~100 DEG C of temperature range.
Fig. 3 chain lines represent the monomer resin volume of lens.For the resin volume, (it polymerize by resin by injection Property monomer) near room temperature (15 DEG C~25 DEG C or so) at initial stage when volume as benchmark in the case of, pass through heating or light Irradiation, resin temperature is further up, while since about 40 DEG C, its volume slowly increases (thermal expansion).Then, from about Temperature beginning more than 60~70 DEG C, the volume of resin starts smaller (cure shrinkage) than initial base volume.Afterwards, volume is poly- Close that reaction terminates and resin reaches minimum when foring polymer.In addition, the volume contraction of the resin as caused by the polymerisation Rate is different also according to species of resin etc., but usually most is 80~98% or so of free state volume.
Dotted line represents bonding force in Fig. 3.In the adhesive tape 1 of present embodiment, have the property that：In near room temperature (15 DEG C~25 DEG C or so) play highest adhesion strength and cohesiveness, but are slowly reduced as temperature rises its cohesiveness.
Due to heating or reaction heat (usual 40 DEG C of thermal expansion occurs for the monomer resin for the lens being filled in vestibule C ~70 DEG C), the volume increase compared with the base volume at initial stage.Afterwards, polymerization temperatures range (usual 60 DEG C~100 DEG C) is being reached When, polymerisation is carried out, is shunk compared with the base volume at initial stage.In the high adhesive tape of pervious cohesiveness, to thermal expansion Tracing ability it is poor, bonding plane, 1 mutual overlap of adhesive tape in adhesive tape 1 and mould 30 produce gap, resin liquid leakage, Notch is produced on lens as a result.On the other hand, in the low adhesive tape of former cohesiveness, as shown in figure 4, due to viscose glue Fixed force with 100 pairs of moulds 30,30 diminishes, therefore, because the convergent force of resin causes mould 30,30 to resist the solidifying of adhering agent layer Poly- power, moves the surface of adhering agent layer, mutually carries out, close to movement, producing thickness change as a result.
However, in the adhesive tape 1 of present embodiment, since the retentivity at 70 DEG C is 50~500 minutes, In 40 DEG C~70 DEG C of the temperature range that the thermal expansion of the monomer resin of lens occurs, in the bonding plane of adhesive tape and mould, adhesive tape Overlap do not occur gap, can suppress liquid leakage generation, can prevent the generation of lens notch.In addition, even in production In the temperature range of 60 DEG C of resiniferous cure shrinkage~100 DEG C, the abundant cohesiveness of fixing mould 30,30 is also can obtain, Mould 30,30 does not follow the surface of adhering agent layer 3 and static.Thus, by using the adhesive tape 1, Neng Goufang of present embodiment Only the thickness of basic performance as products formed, curvature change.
It is less than 50 points in 70 DEG C of the retentivity according to JIS Z0237 (ISO29862) of the adhesive tape 1 of present embodiment In the case of clock, due to that cannot obtain the abundant fixed force to the cure shrinkage of the monomer resin of lens, mould 30,30 is followed viscous The surface of oxidant layer 3, the distance between mould produces deviation, and it is therefore possible to the lens thickness after being molded to change.The opposing party Face, the adhesive tape 1 of present embodiment 70 DEG C of retentivity more than 500 minutes in the case of, the thermal expansion to lens monomer Tracing ability it is poor, bonding plane, 1 mutual overlap of adhesive tape in adhesive tape 1 and mould 30 produce gap, and resin occurs Liquid leaks, and is possible to produce notch on lens as a result.70 DEG C of retentivity be more preferably more than 80 minutes, 300 minutes with Under.
In the case where the adhesive tape 1 of present embodiment is below 2.0N/10mm relative to the adhesion strength to glass, having can The cementability of energy adhesive tape and mould reduces, it is impossible to follows the thermal response of lens monomer, adhesive tape comes off.On the other hand, in this reality Apply the adhesive tape 1 of mode relative to the adhesion strength to glass more than 6.0N/10mm in the case of, the cementability of adhesive tape and mould Increase, when adhesive tape is peeled off, it is possible to residue glue is produced on mould.
