Description

  The present disclosure relates to a cleaning composition for a plastic lens molding glass mold, a cleaning method for a plastic lens molding glass mold using the cleaning composition, and a manufacturing method for a plastic lens.

  In recent years, glasses lenses, contact lenses, camera viewfinders, photographing lenses, projection TV lenses, large screen Fresnel lenses, lenticulars, sunlight condensing lenses, overhead projector type Fresnel lenses, compact disc lenses, light Lenses and prisms for optical devices such as memory objective lenses have been converted from glass materials to plastic materials. In particular, for eyeglass lenses, (hard) coating technology that prevents scratches on the surface has been developed, scratch resistance has reached a level that does not become a practical problem, high refractive index materials have been developed, and thinner and lighter lenses As a result, it is possible to significantly increase the conversion ratio from glass to plastic.

  Resin stains such as plastic lens resin, adhesives, and adhesives attached to optical parts such as plastic lenses or glass molds and jigs used in the manufacturing process adhere firmly to the hard surface. In addition, since the molecular weight of the resin soil itself is high, it is very difficult to clean with chemicals utilizing dissolution, swelling, softening, disintegration, peeling action, and the like. Among them, the plastic lens resin adhered to the glass mold during the production of the plastic lens has a very high molecular weight and is one of the most difficult to clean resin stains.

  Resins for plastic lenses include resins obtained by radical polymerization of diethylene glycol bisallyl carbonate, methacrylic resins, fumaric acid ester / allyl monomer copolymer resins, triazine ring acrylic resins, polycarbonate resins, bromine-containing resins, urethanes Resin, sulfur-containing urethane resin, thioether / ester resin and the like are used. The most widely used resin for plastic lenses is a resin obtained by radical polymerization of allyl diglycol carbonate (ADC). However, recently, a resin material having a higher refractive index has been developed. Typical examples are sulfur-containing plastic lens resins having a refractive index of 1.55 or more, such as sulfur-containing urethane resins, sulfur-containing epoxy resins, polythio (meth) acrylate resins, sulfur-containing poly (meth) acrylate resins, and episulfide resins. is there.

  As a general method of manufacturing a plastic lens, a mold composed of a pair of glass molds having a predetermined curvature on the inner surface and an annular packing (gasket) or tape made of a synthetic resin attached to the outer peripheral side thereof is used. It is carried out by a method of polymerizing by heating after injecting the monomer of the forming material. After this polymerization step, the annular packing is removed from the mold, and the glass mold and the plastic lens substrate are released from the mold. Since the finished plastic lens base material has a non-uniform outer peripheral part, the outer peripheral part is shaped, and the edge part is chamfered and sent to the cleaning process. After washing the oligomer and polymer stains attached to the lens surface at the time of mold release, polymer powder adhering to the outer periphery shaping and chamfering, unreacted monomer remaining on the lens surface, and other dust in the atmosphere, dyeing, hard coating, antireflection Surface treatment such as coating, aqua coating, etc. is applied to make a product.

  At this time, the used glass mold is washed and used again as a mold. In the case of plastic lenses for eyeglasses, there are many thousands of types of lenses, and many types are produced in small quantities. Therefore, the required glass mold is enormous and the manufacturing cost per plastic lens is high. Become. Therefore, if a single glass mold can be used over and over again, the ratio of the cost of the glass mold to the production of the plastic lens is reduced, and as a result, the plastic lens can be produced economically advantageously. It becomes like this. Glass molds used in the production of plastic lenses are very expensive and are used repeatedly hundreds to thousands of times unless broken. Therefore, like the plastic lens itself, it is necessary to wash the oligomers and polymer-like stains derived from the raw material spilled during the monomer injection. If the glass mold is not clean, a good-quality plastic lens with a smooth surface cannot be obtained, and the glass mold must be discarded. As a result, it is also very uneconomical. In such a background, the following cleaning composition and cleaning method have been proposed.

  For example, in Patent Document 1, as a detergent composition for resin stains that is excellent in cleaning properties and safety against resin stains, compounds such as aromatic monocyclic compounds and 1,4-butanediol, glycol ether compounds, and A cleaning composition for resin soil containing an ethylene glycol compound, an aromatic compound, a metal sealant, an alkali metal hydroxide, and a cleaning composition for resin soil containing water are disclosed. Disclosed is a method for cleaning resin soils using an agent composition.

  Patent Document 2 discloses an aromatic compound 10 as a cleaning composition for a plastic lens molding glass mold, which is excellent in cleaning properties against high molecular weight resinous stains and safety to the human body during cleaning, and does not corrode the molding glass mold. For plastic lens molding glass molds containing ~ 94 wt%, alkali agent 0.1-50 wt%, calcium ion releasing substance 0.005-25 wt% [calcium ion equivalent] and water 5-89 wt% A cleaning composition and a method for cleaning the glass mold using the same are disclosed.

  Patent Document 3 discloses (a) an inorganic alkaline agent in an amount of 2 to 30% by weight and (b) an anion having a high detergency against a high refractive index sulfur-containing plastic lens resin stain having a refractive index of 1.55 or more. 0.5 to 20% by weight of at least one surfactant selected from surfactants and nonionic surfactants, (c) 0.01 to 2% by weight of calcium salt (calcium ion equivalent), (d) calcium ions A cleaning composition containing 0.1 to 15% by weight of scavenger, (e) 1 to 30% by weight of a water-soluble organic solvent, and (f) 20 to 95% by weight of water is disclosed.

And a high quality plastic lens can be obtained by using the cleaning composition concerning this indication.

The flowchart explaining an example of the manufacturing method of the plastic lens of this invention

  In the present disclosure, when a cleaning composition containing each of the above components A to D at a predetermined content is used for cleaning a plastic lens-molded glass mold, the glass mold surface is suppressed while suppressing corrosion of the glass mold surface. It is based on the knowledge that the remaining plastic lens resin (hereinafter sometimes abbreviated as “resin”) can be efficiently washed, and the quality of the plastic lens does not deteriorate even when used repeatedly for a long time.

  That is, in one embodiment of the present disclosure, the aromatic alcohol (component A) is 20% by mass or more and 40% by mass or less, the inorganic alkali (component B) is 2% by mass or more and 8% by mass or less, and is represented by the above formula (I).

And a high quality plastic lens can be obtained by using the cleaning composition concerning this indication.

  Although the details of the action mechanism of the effect in the cleaning composition according to the present disclosure are unclear, it is estimated as follows.

  The resin for plastic lenses that adheres to the glass mold is a chemically stable substance, and it is difficult to remove the resin from the glass mold while simultaneously protecting the glass mold and decomposing the resin. Is generally applied to the interface between the glass mold and the resin and peels off. In particular, a sulfur-containing plastic lens resin that achieves high refraction tends to be chemically stable and strong in adhesion to glass. Therefore, in order to remove the resin from the glass mold, a method is generally used in which the cleaning agent penetrates the interface between the glass mold and the resin, and the resin is efficiently peeled off from the glass mold by the action of mechanical force such as stirring and ultrasonic waves. Is often used.

  The presence of the inorganic alkali (component B) in the cleaning composition according to the present disclosure promotes the cleavage of ester bonds present in the resin by hydrolysis and the neutralizing action of residual acid groups, and the glass surface Promotes peeling of resin from On the other hand, the aromatic alcohol (component A) coexists with both the compound represented by the above formula (I) (component C) and the compound represented by the above formula (II) (component D). When component C has a specific concentration and component A has low solubility in water, the solubility of component A in water decreases due to the presence of component B and the mechanical force due to stirring or the like is small. Also, the affinity with water can be increased. Therefore, the component A is likely to permeate the interface between the resin adhering to the glass mold and the glass mold, and the peeling of the resin from the glass mold is promoted. In addition, since the components A to D have specific concentrations, the cleaning composition can accumulate resin stains, absorb carbon dioxide in the air, volatilize highly volatile components, and locally in repeated cleaning over a long period of time. Even under the influence of deterioration due to overheating, it is presumed that the solubility of Component A in water can be maintained, and the high detergency can be maintained without degrading the peelability. Furthermore, by setting the concentration of component B to 2% by mass or more and 8% by mass or less, excessive corrosion of the glass mold surface can be suppressed while maintaining high detergency, and the presence of components C and D makes the glass mold more It is estimated that surface corrosion can be suppressed. However, the present disclosure is not construed as being limited to this mechanism.

  In the cleaning composition according to the present disclosure, when the following anionic surfactant (component F) is included as an optional component, the solubility of component A in water is improved and component F is adsorbed on the glass mold surface, It is estimated that corrosion of the glass mold surface by B can be further suppressed.

  In the cleaning composition according to the present disclosure, when the following calcium is included as an optional component, calcium is adsorbed on the glass surface, or the component F, the following gluconic acid or a salt thereof (component G) forms a calcium salt. By adsorbing to the glass surface, it is estimated that corrosion of the glass mold surface by component B can be further suppressed.

  In the cleaning composition according to the present disclosure, when component G is included as an optional component, calcium due to evaporation of water in long-term use, etc. due to the chelating action of component G and the high solubility of the resulting salt in water It is possible to suppress the precipitation of hardness components such as, suppress the clogging of pipes circulating the cleaning composition, prevent sedimentation of sediments, prevent deposition of deposits on the glass mold, and improve cleaning properties and productivity. It is estimated to be.

  In one aspect of the cleaning composition according to the present disclosure, the above effect acts synergistically, workability and operational stability can be improved, and even after repeated cleaning for a long period of time, the cleaning performance is not reduced, It is estimated that the number of renewal of the cleaning composition can be reduced, the glass mold can be used repeatedly, and the productivity of high-quality plastic lenses is improved.

  However, the present disclosure is not construed as being limited to these mechanisms.

  The cleaning composition according to the present disclosure can be applied to a resin for a high refractive index plastic lens having a refractive index of 1.55 or more that is difficult to peel off. It can also be suitably used for cleaning.
