Embodiment
The embodiment of adhesion zone and plastic lens molding method for the plastic lens molding that present invention will be described in detail with reference to the accompanying relates to.Fig. 1 is the sectional drawing of adhesion zone for plastic lens molding (sectional drawing that the plane by the length direction quadrature with band cuts off) of the present embodiment, and Fig. 2 is the figure of the plastic lens molding method of explanation the present embodiment.It should be noted that, in each figure afterwards, for identical or suitable part, the symbol that additional phase is same.
As shown in Figure 1, the plastic lens of the present embodiment has following structure with adhesion zone 100: at the single face of banded base material (hereinafter sometimes also referred to as band base material) 10, roughly be provided with the adhesive coating 20 that it is adhered to mould 30,30 on whole.
Then, illustrate and use such plastic lens molding to use adhesion zone 100 by the method for plastic lens molding.
At first, as shown in Figure 2, after for example roughly discoideus a pair of mould 30,30 separates the interval subtend configuration of regulation, plastic lens molding is reeled and adhered to along peripheral direction in the periphery edge of two moulds 30,30 with adhesion zone 100, in the situation that keep described interval that the opening in the space of formation between two moulds 30,30 is sealed continuously.Like this, as shown in Figure 2, mould 30,30 mutual almost parallel ground are connected, cut apart betwixt and form tabular or chamber C cylindraceous (chamber formation operation) simultaneously.
So, if formed such chamber C, as shown in Figure 2, plastic lens molding is peeled off and opening clearance with an end of adhesion zone 100, by not shown nozzle from this insertion chamber, gap C.So, inject liquid resin (polymerizable monomer) from this nozzle and filling in the C of chamber, again plastic lens molding for this gap is stopped up to (monomer filling procedure) with adhesion zone 100.
As resin (polymerizable monomer), use the mixture of m-eylylene diisocyanate and tetramethylolmethane four mercaptopropionic acid esters, the perhaps mixture of m-eylylene diisocyanate and two (mercaptoethyl) trithio glycerine etc., but be not limited to especially these.
Further, after this, load onto not shown stationary fixture and in the situation that not change described interval fixing by mould 30,30.Because mould 30,30 is fixed by stationary fixture, even the interior pressure of chamber C changes, described interval does not change yet, and maintains certain interval constantly.So, by heating or illumination, make resin (polymerizable monomer) polymerization reaction take place in the C of chamber harden (polymerization process).Resin (polymerizable monomer) is all peeled off plastic lens molding with adhesion zone 100 after fully hardening, and by mould 30,30 dismountings, obtains plastic lens.
At such plastic lens molding, use in adhesion zone 100, adhesive coating 20 is comprised of following tackiness agent: this tackiness agent take comprise more than 80 quality % the addition reaction-type organosilicon tackiness agent below 95 quality % and more than 5 quality % the mixture of the superoxide sclerotic type organosilicon tackiness agent below 20 quality % be principal constituent, with respect to these mixture 100 mass parts, mix forming below 0.20 mass parts more than effective linking agent 0.12 mass parts of described addition reaction-type organosilicon tackiness agent.
Such adhesive coating 20 is owing to having sufficient clinging power, when the chamber C resin by injection (polymerizable monomer) formed with adhesion zone 100 and a pair of mould 30,30 to plastic lens molding, can positively resin (polymerizable monomer) be sealed in the C of chamber and make this resin (polymerizable monomer) not leak.
In addition, superoxide sclerotic type silicone adhesive contains silanol and low-molecular-weight siloxane (being mainly the ring-type of 3～20 polymers and/or the dimethyl polysiloxane of straight chain shape) as impurity, because these impurity are sneaked into resin (polymerizable monomer) from adhesive coating 20 strippings, in the prior art, there are the inside of the plastic lens after sclerosis and the risk that the periphery edge produces above-mentioned white casse and bubble.
But, the tackiness agent of using adhesion zone 100 to use for the plastic lens molding of the present embodiment, the ratio of the superoxide sclerotic type organosilicon tackiness agent in the mixture of addition reaction-type organosilicon tackiness agent and superoxide sclerotic type organosilicon tackiness agent is low to moderate below 20 quality %, therefore, the first, the stripping quantity of silanol is few.Thus, the inside of the plastic lens after sclerosis and periphery edge are difficult to produce bubble.
Further, second, the tackiness agent of using adhesion zone 100 to use for the plastic lens molding of the present embodiment, by embodiment processing described as follows, make the content of the low-molecular-weight siloxane of 3～20 polymers in this tackiness agent take tackiness agent that described mixture is principal constituent below 4850 μ g with respect to every 1g, so the stripping quantity of low-molecular-weight siloxane (being mainly the ring-type of 3～20 polymers and/or the dimethyl polysiloxane of straight chain shape) significantly reduce.Thus, the inside of the plastic lens after sclerosis and periphery edge are difficult to produce white casse.
The processing of the content of the low-molecular-weight siloxane in the tackiness agent used with adhesion zone 100 for the plastic lens molding that reduces the present embodiment, in superoxide sclerotic type organosilicon tackiness agent and addition reaction-type organosilicon tackiness agent, have at least necessity to implement superoxide sclerotic type organosilicon tackiness agent.The treatment process that reduces the content of the low-molecular-weight siloxane in superoxide sclerotic type organosilicon tackiness agent is not subject to special restriction, is preferably to starting material or the superoxide sclerotic type organosilicon tackiness agent of superoxide sclerotic type organosilicon tackiness agent are implemented thermal treatment or reduced pressure treatment, made the low-molecular-weight siloxane volatilization and the method for minimizing.
Amount for low-molecular-weight siloxane, in the figure of the quantitative analysis with the GC-FID device shown in Fig. 4 (D-n in Fig. 4 (integers of n=3～20) means the n-mer of low-molecular-weight siloxane), the amount of the dimethyl polysiloxane of 3～20 polymers be take tackiness agent that described mixture is principal constituent below 4850 μ g with respect to every 1g, preferably, the amount of the dimethyl polysiloxane of 3～10 polymers is below 165 μ g, further preferably, the amount of the dimethyl polysiloxane of 3～10 polymers is below 50 μ g, preferably fully suppresses the amount of the generation of white casse.It should be noted that, dimethyl polysiloxane both can be for ring-type can be also the straight chain shape, and the amount of described dimethyl polysiloxane is the amount that cyclic dimethyl polysiloxane and straight chain shape dimethyl polysiloxane add up to.
The method reduced as making the low-molecular-weight siloxane volatilization, for example enumerate organo-silicone rubber or MQ (M unit: (CH that (1) will form the organosilicon tackiness agent
3)
3SiO
1/2, Q unit: SiO
2) resin makes the low-molecular-weight siloxane volatilization under reduced pressure high-temperature stirring or mixing (the decompression desorb) of starting material stage in advance, reduce thus the method for processing, (2) in the stage of organo-silicone rubber or MQ mixed with resin being manufactured to basic tackiness agent, under decompression or normal pressure, heat, make the low-molecular-weight siloxane volatilization, reduce thus the method for processing, perhaps heat in the coating of base material, drying process at organosilicon tackiness agent solution (3), low-molecular-weight siloxane is volatilized from adhesive coating, reduce thus the method for processing.By these treatment process combinations, be also possible.If consider productivity, cost, tackiness agent being launched into netted, effectively to make on low-molecular-weight siloxane volatilization this point be most preferred to the treatment process that roughly is equivalent to (3).By implementing such processing, can reduce the stripping quantity of low-molecular-weight siloxane from the organosilicon tackiness agent.Thus, the inside of the plastic lens after sclerosis and periphery edge are difficult to produce white casse.
Temperature while reducing the processing of amount of low-molecular-weight siloxane is not particularly limited, preferably more than the polymerization temperature of the resin (polymerizable monomer) when the lens moulding, the thermal treatment carried out more than the top temperature that particularly reaches during polymerization.By such thermal treatment, can make low-molecular-weight siloxane volatilize from the organosilicon tackiness agent.Heat treated temperature is according to the kind of resin (polymerizable monomer) and difference, preferably more than 130 ℃, more preferably more than 150 ℃, further preferably more than 180 ℃.It should be noted that, for the temperature that surpasses 200 ℃, the risk that existence was cut off the main chain of organopolysiloxane, make on the contrary low-molecular-weight siloxane increase on the contrary according to the treatment time, perhaps for the treatment process of above-mentioned (3), there is the risk of base material distortion, therefore preferably make to be limited to 200 ℃.
In addition, condition beyond temperature during thermal treatment, treatment time or the atmosphere (kind of atmosphere gas for example, air pressure, gas velocity), be not subject to special restriction yet, as long as heat-treat condition is set as meeting the following conditions: the amount of the dimethyl polysiloxane of 3～20 polymers in the tackiness agent that the described mixture of take is principal constituent be take tackiness agent that described mixture is principal constituent below 4850 μ g with respect to every 1g, preferably, the amount of the dimethyl polysiloxane of 3～10 polymers be take tackiness agent that described mixture is principal constituent below 165 μ g with respect to every 1g, further preferably, the amount of the dimethyl polysiloxane of 3～10 polymers be take tackiness agent that described mixture is principal constituent below 50 μ g with respect to every 1g, fully suppress the generation of white casse.It should be noted that, in the situation that do not implement this processing, the amount of low-molecular-weight siloxane (dimethyl polysiloxanes of 3～20 polymers) be take with respect to every 1g the tackiness agent that described mixture is principal constituent and is surpassed 4850 μ g.
Further, be not particularly limited the opportunity of processing that tackiness agent implement is reduced to the amount of low-molecular-weight siloxane, can implement the independent superoxide sclerotic type organosilicon tackiness agent before mixing with addition reaction-type organosilicon tackiness agent, also can implement the mixture of addition reaction-type organosilicon tackiness agent and superoxide sclerotic type organosilicon tackiness agent, also can implement after to this mixture, having mixed described linking agent.That is, can implement described processing in the feed stage of tackiness agent, also can implement described processing to the tackiness agent completed.In addition, can or after completing, implement adhesive coating 20 described processing when the tackiness agent solution coat is formed to adhesive coating 20 in band base material 10.Particularly, for under the state in addition reaction-type organosilicon tackiness agent and the mixing of superoxide sclerotic type organosilicon tackiness agent, implementing heat-treating methods, because the low-molecular-weight siloxane in not only superoxide sclerotic type organosilicon tackiness agent but also addition reaction-type organosilicon tackiness agent is reduced, therefore more preferably.
Like this, if use the plastic lens molding of the present embodiment to manufacture plastic lens with adhesion zone 100, the inside and the periphery edge that are difficult to the plastic lens after sclerosis produce white casse and bubble, therefore can manufacture plastic lens with good yield.
It should be noted that, although for the present embodiment at the single face with base material 10 (bonding plane) adhesive coating 20 is set on the whole, but as shown in Figure 3, also can be only in base material 10 zone (both sides) of each mould 30,30 of adhesion adhesive coating 20 is set.If take such structure, can cut down the consumption of the tackiness agent that forms adhesive coating 20, can suppress low-molecular-weight siloxane in tackiness agent or silanol to the stripping in monomer, a part that is difficult in addition to produce tackiness agent is attached to the so improper situation of products formed simultaneously.
Below, for the plastic lens molding that forms the present embodiment with band base material 10, the adhesive coating 20 of adhesion zone 100 and be elaborated as the raw-material organosilicon tackiness agent of tackiness agent (being addition reaction-type organosilicon tackiness agent, superoxide sclerotic type organosilicon tackiness agent), linking agent.
Addition reaction-type organosilicon tackiness agent is not subject to special restriction, can enumerate for example 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, perhaps TSR1512, TSR1516, the XR37-B9204 of モ メ Application テ イ Block パ Off オ mono-マ Application ス マ テ リ ア Le ズ society system, SD4584, SD4585, SD4560, SD4570, SD4600PFC, the SD4593 of Huo person East レ ダ ウ コ mono-ニ Application グ Co., Ltd. system.
In addition, superoxide sclerotic type silicone adhesive is not subject to special restriction, can enumerate for example KR100, the KR101-10 of Shin-Etsu Chemial Co., Ltd's system, perhaps YR3340, YR3286, PSA610-SM, the XR 37-B6722 of モ メ Application テ イ Block パ Off オ mono-マ Application ス マ テ リ ア Le ズ society system, the SH4280 of Huo person East レ ダ ウ コ mono-ニ Application グ Co., Ltd. system.
The mixture of addition reaction-type organosilicon tackiness agent and superoxide sclerotic type organosilicon tackiness agent, comprise the following addition reaction-type organosilicon tackiness agent of the above 95 quality % of 80 quality % and the following superoxide sclerotic type organosilicon tackiness agent of the above 20 quality % of 5 quality %, and if the ratio of superoxide sclerotic type organosilicon tackiness agent surpasses 20 quality % (if i.e. the ratio less than 80 quality % of addition reaction-type organosilicon tackiness agent), because the ratio of superoxide sclerotic type organosilicon tackiness agent is too much, the silanol of stripping or the quantitative change of low-molecular-weight siloxane are many, become and easily produce bubble and white casse in the inside of plastic lens and periphery edge.
On the other hand, if the ratio less than 5 quality % of superoxide sclerotic type organosilicon tackiness agent (if the ratio of addition reaction-type organosilicon tackiness agent surpasses 95 quality %), the clinging power of adhesive coating 20 becomes insufficient, be difficult to the interval of using adhesion zone 100 to keep between two moulds 30,30 by plastic lens molding, exist the liquid that produces polymerizable monomer to leak the risk of the circumference defect caused.In addition, owing to easily at plastic lens and two mould 30,30 places, producing removing residual glue, produce the necessity of grinding the plastic lens peripheral part or the necessity of removing and washing of carrying out the glue of mould 30, the risk that exists utilization ratio and operability to reduce.Particularly, the polymerization temperature of the polymerizable monomer when manufacture specific refractory power is the high refractive index lens more than 1.60 is the high temperature more than 130 ℃, even therefore in order to give adhesive coating 20, also can keep the clinging power at described interval under such high temperature, be necessary to use the superoxide sclerotic type organosilicon tackiness agent of at least 5 quality %.
Further, in the tackiness agent that is principal constituent at mixture of take addition reaction-type organosilicon tackiness agent and superoxide sclerotic type organosilicon tackiness agent of the present invention, in order to obtain the balance of adhesiveness, add only to the effective linking agent of addition reaction-type tackiness agent mixing.The effective linking agent of addition reaction-type organosilicon tackiness agent is not subject to special restriction, can enumerate for example X-92-122 of Shin-Etsu Chemial Co., Ltd's system, the perhaps CR50 of モ メ Application テ イ Block パ Off オ mono-マ Application ス マ テ リ ア Le ズ society system, the BY24-741 of Huo person East レ ダ ウ コ mono-ニ Application グ Co., Ltd. system.
It is preferred that the effective linking agent of addition reaction-type organosilicon tackiness agent is mixed with the amount below 0.20 mass parts more than 0.12 mass parts with respect to described mixture 100 mass parts.If less than 0.12 mass parts, during the polymerizable monomer polymerization, the clinging power of tackiness agent becomes insufficient, and existence can not keep the risk at described interval.Consequently the expansion of polymerizable monomer causes the liquid occurred from chamber C to leak, and exists the plastic lens obtained to produce the risk of defect.
On the other hand, if surpass 0.20 mass parts, because the clinging power of tackiness agent is excessively strong, even polymerizable monomer shrinks and also keeps described interval during the polymerizable monomer polymerization, so plastic lens molding with adhesion zone 100 the radial center side stretching at mould 30.Consequently, there is the risk that for plastic lens molding, adhesion zone 100 generation folds, lens fold enter the periphery of plastic lens.
Secondly, the material of base material 10 is not particularly limited, and the material that the polyethylene terephthalate of still take is principal constituent is most suitable.But be not limited to this, also can use other material.
For example, can use the tinsels such as stainless steel, soft aluminium, or the resin moldings such as polybutylene terephthalate, PEN, polyphenylene sulfide, biaxial stretch-formed polypropylene, polyimide, aromatic polyamide, poly-cycloolefin, fluoro-resin.In addition, also can use aluminium foil and the stacked composite membrane formed of resin molding, or film and the stacked composite membrane formed of resin molding that the metal oxide films such as aluminum oxide, silicon-dioxide are formed at surface resin film.
In the situation that use polyethylene terephthalate as being with base material 10, preferably make its thickness more than 20 μ m in the scope below 75 μ m.For less than 20 μ m, because the rigidity of base material 10 is low, existence can not keep the risk at the interval between two moulds 30,30.In addition, there is following risk: the power can not resistance resin (polymerizable monomer) expanded and occur disrumpent feelings etc., air is invaded in the C of chamber, and the power of can not resistance resin (polymerizable monomer) shrinking and shrinking at width becomes the reason produced with fold.On the other hand, if surpass 75 μ m, because the rigidity of base material 10 is high, the risk that exists retractility to reduce.In addition, there is the risk of the liquid leakage that produces gap at plastic lens molding in the overlap with adhesion zone 100, resin (polymerizable monomer) occurs.
Manufacture method as plastic lens molding with adhesion zone 100, the method be listed below: addition reaction-type organosilicon tackiness agent and superoxide sclerotic type organosilicon tackiness agent are dissolved in to toluene, organic solvents such as dimethylbenzene and obtain tackiness agent solution, in this tackiness agent solution, add the effective linking agent of addition reaction-type organosilicon tackiness agent, so that the mode of the even thickness of dried adhesive coating 20 is taken turns coating machine (コ Application マ コ mono-タ mono-) by this solution by unfilled corner, after lip coating machine (リ Star プ コ mono-タ mono-) etc. is coated base material 10, temperature drying by regulation, sclerosis.As required, also can between adhesive coating and base material 10, the anchoring treatment layer be set.
But plastic lens molding is not limited to aforesaid method by the manufacture method of adhesion zone 100, the common manufacture method adopted for the silicon-type adhering agent layer is formed to base material, anyly all can adopt.It should be noted that, if temperature etc. is set as to suitable condition, can be by amount dry, that thermal treatment while hardening reduces low-molecular-weight siloxane, by superoxide sclerotic type organosilicon tackiness agent being applied to the processing of the amount that reduces low-molecular-weight siloxane, the superoxide sclerotic type organosilicon tackiness agent that has applied this processing is dissolved in to organic solvent, also can manufactures the tackiness agent that forms adhesive coating 20.
The thickness of adhesive coating 20 is usually more than 10 μ m in the scope below 35 μ m.If less than 10 μ m, plastic lens molding becomes insufficient with the intersection between adhesion zone 100 and mould 30 bond strengths, and the intrusion of liquid leakage or air easily occurs.In addition, if surpass 35 μ m, plastic lens molding becomes too thick by the total thickness of adhesion zone 100, easily at overlap, produces gap.Further, lower-molecular substance (silanol and low-molecular-weight siloxane) also becomes many from the stripping quantity of adhesive coating 20, easily in plastic lens, produce white casse and bubble, even implement in addition the processing of the amount of minimizing low-molecular-weight siloxane, also be difficult to reduce the amount of low-molecular-weight siloxane.
Although use such plastic lens molding to manufacture plastic lens with adhesion zone 100, the shape of the mould 30 now used, material etc. are not subject to special restriction.But, glass (silicon-dioxide) system that general many uses are discoideus or metal.
In addition, the kind as the resin (polymerizable monomer) of the raw material of plastic lens is not subject to special restriction yet.In the situation that eyeglass lens is used existing well known materials, for example in the situation that the eyeglass lens of superelevation specific refractory power (1.65≤Ne), using episulfide is that resin (MR-174 processed of Mitsui Chemicals, Inc, the IU-20 processed of Mitsubishi Gas Chemical Co., Ltd) or thioxanthamide are the monomer of resin (MR-7 processed of Mitsui Chemicals, Inc) etc.
