The present invention in the color lock manufacture method of contact lens as printing color, first adds firming agent in the clear dope polymer manufactured and is stirred。
Described clear dope polymer is made through following steps, and described step has: whipping step, by 2-hydroxyethyl methacry-late (2-HEMA；2-Hydroxyethylmethacrylate) 20～60 weight %, 2.2'-azodiisobutyronitrile (AIBN；2.2'-Azobisisobutyronitrile (98%)) 0.3～5 weight %, methyl methacrylate (MMA；Methylmethacrylate (99%)) 0.3～20 weight %, allyl methacrylate (Allylmethacrylate) 10～20 weight % put in aggregation container stir 1～8 hour；Implement polymerization procedure, described aggregation container is put into and while adding catalyst to the water heater of maintenance-10～+10 DEG C, implements polymerization 5～10 hours；Heat radiation step, stops polymerization and moves on to heat radiation while other container is stirred when polymer gel state；Stored refrigerated step, puts into after polymer heat radiation and carries out-5～20 DEG C of stored refrigerated in opaque preservation container。
Clear dope polymer 70～99.5 weight % as above adds firming agent 0.5～30 weight % stirring, stirs 5～60 minutes being completely dissolved to firming agent。
Firming agent hexamethylene diisocyanate (HDI；Hexamethylenediisocyanate)。
Hereafter the clear dope polymer of stirring is spread upon formation coating on the mould of top。The etched plate used in the step smearing described clear dope polymer is to corrode with the numerical range of external diameter 4.0～12mm, internal diameter 1.5～6.5mm, the degree of depth 3～20 μm。After the corrosion location of described etched plate is smeared clear dope polymer, use cushion device thus spreading upon on the mould of top。
Hereafter, the coating being formed at top mould uses cushion device print color。
Then, clear dope polymer after stirring is filled pottery ink cup and is prepared work (warmingup), on the mould of top, daub polymer is formed after coating and by color dyes method on lens is, making a movement before and after after various color fills pottery ink cup, at this moment leaving color inks remainder at the erodable section of etched plate can be very clean。Cushion device is now utilized to carry out colored transfer painted。
Described etched plate is to corrode with the numerical range of external diameter 5.0～12.4mm, internal diameter 1.5～7mm, the degree of depth 3～25 μm。
Hereafter, lens polymerization thing adds firming agent to be stirred。
The use of described lens polymerization thing is made through following steps, and described step has: whipping step, by 2-hydroxyethyl methacry-late (2-HEMA；2-Hydroxyethylmethacrylate) 20～60 weight %, 2.2'-azodiisobutyronitrile (AIBN；2.2'-Azobisisobutyronitrile (98%)) 0.3～5 weight %, methyl methacrylate (MMA；Methylmethacrylate (99%)) 0.5～20 weight %, allyl methacrylate (Allylmethacrylate) 0.5～20 weight % put in aggregation container stir 5～10 hours；Implement polymerization procedure, described aggregation container is put into and while adding catalyst to the water heater of maintenance-15～+10 DEG C, implements polymerization 5～10 hours；Heat radiation step, stops polymerization and moves on to heat radiation while other container is stirred when polymer gel state；Stored refrigerated step, puts into after polymer heat radiation and carries out-5～+20 DEG C of stored refrigerated in opaque preservation container。
Lens polymerization thing 70～99.5 weight % as above adds firming agent 0.5～30 weight % stirring, stirs 5～60 minutes being completely dissolved to firming agent。
Firming agent hexamethylene diisocyanate (HDI；Hexamethylenediisocyanate)。
Hereafter the lens polymerization thing of stirring is fed between top mould and bottom mould thus manufacturing lens。
Lens polymerization thing is injected thus manufacturing in the step of lens between the mould of lens top and the bottom, foreign body and impurity must not be allowed to be mixed into, smear between from internal diameter 2.5～7.0mm to external diameter 5.5～12.3mm and carry out, it is preferable that smear between external diameter 12.2mm from internal diameter 2.5mm。
Additionally, the lens thickness injecting the formation of lens polymerization thing ranges for 0.003～0.2mm, it is preferable that process as 0.05mm。
Hereafter the lens of described manufacture are carried out heat treatment。Heat treated step is the heat treatment carried out at 60～130 DEG C 20～90 minutes。
Place 5～10 seconds in room temperature 20 DEG C when not carrying out heat treatment。
It addition, the printing color of the manufacture present invention is when the color lock of contact lens, for manicure lavatory system, the temperature of described manicure lavatory is 18～35 DEG C, and relative humidity is 10～70%, so that color printing is uniform。
Additionally, coating is put into hothouse with 60～130 DEG C after dry 20～90 minutes, utilizing cushion device to carry out bat printing operation thus forming uniform layer, described coating is to spread upon the clear dope polymer of stirring in described coating process step to be formed on the mould of top。
Fig. 2 is the skeleton diagram illustrating job engineering, and Fig. 3 is the model photo according to operation of the present invention。
Job engineering prepares moulds-2. through 1. and smears mould-3. printing-4. and monomer flows into bottom mould-5. combine-6. separation engineerings。
Therewith, have following remarkable result: portion smooth that the method according to the invention is smeared, for a long time wear without produce the senses of discomfort such as foreign body sensation, lens intensity strong and durability is high, bad product is few。
