Description

Cleaner composition for plastic lens molding glass type

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 of a plastic lens.

Recently, eyeglass lenses, contact lenses, camera finders, shooting lenses, projection television lenses, large screen fresnel lenses, lenticulars, solar condensing lenses, overhead projector type fresnel lenses, compact disc lenses, optical Lenses, prisms, and the like for optical devices such as memory objective lenses have been converted from glass materials to plastic materials. In particular, the spectacle lens has developed a (hard) coating technology that prevents scratches on the surface, and scratch resistance has become a level that does not become a problem in practical use, and a material having a high refractive index has been developed to process thinner and lighter lenses. By becoming possible, elongation of the conversion ratio from glass to plastic is remarkable.

Resin contaminants, such as resins for plastic lenses, adhesives, and adhesives attached to optical components such as plastic lenses or glass and dental tools used in the manufacturing process thereof, are firmly adhered (adhered) to hard surfaces, and the resin contaminants themselves. Because of its high molecular weight, it is very difficult to clean with a drug using dissolution, swelling, softening, disintegration, and peeling action. Among them, the resin for plastic lenses attached to the glass in the production of the plastic lens has a very high molecular weight and is one of the resin contaminants that is most difficult to clean.

As resin for plastic lenses, resin obtained by radical polymerization of diethylene glycol bisallylcarbonate, methacrylic resin, fumaric acid ester / allyl monomer copolymer resin, triazine ring acrylic resin, polycarbonate resin, bromine compound resin, urethane type Resins, sulfur-containing urethane resins, thioether ester resins, 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). Recently, however, higher refractive index resin materials have been developed. Typical examples thereof 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.

In general, a method for producing a plastic lens is formed in a mold composed of an annular packing (gasket) or tape made of a pair of glass having a predetermined curvature on its inner surface and a synthetic resin mounted on its outer peripheral edge. It is performed by the method of heat-polymerizing after inject | pouring a monomer. After this polymerization process, the cyclic packing is removed from the mold, and the glass and plastic lens base materials are released. Since the outer peripheral part has a non-uniform shape, the completed plastic lens base material is subjected to outer circumferential shaping, chamfering of the edge portion further, and sent to the washing step. After removing the oligomers and polymeric contaminants adhered to the lens surface at the time of release, the polymer particles adhered at the time of outer shaping and chamfering, unreacted monomers remaining on the lens surface, dust in other atmospheres, and then dying and hardening. Surface treatment of a coat, an antireflective coat, an aqua coat, etc. is given and it becomes a product.

At this time, the used glass mold is washed and used again as a mold. In the case of the plastic lens for spectacles, since the lens has many kinds and many kinds of small quantities are produced, the required glass type is enormous, and the manufacturing cost per one plastic lens becomes high. Therefore, if one glass mold can be used repeatedly, the ratio of the cost of the glass mold in the production of the plastic lens is reduced, and as a result, the plastic lens can be economically advantageously manufactured. Since the glass mold used in the manufacture of plastic lenses is very expensive, it is used repeatedly hundreds to thousands of times unless it is broken. Therefore, as with the plastic lens itself, it is necessary to clean oligomers, polymeric contaminants, etc. derived from the raw materials overflowed during monomer injection. If the glass mold is not clean, a high quality plastic lens with a smooth surface cannot be obtained, and the glass mold cannot be discarded. As a result, it is also very uneconomical. In such a background, the following cleaning composition and cleaning method are proposed.

For example, Patent Literature 1 discloses a cleaning composition for resin contaminants that is excellent in cleaning property and safety against resin contaminants, and compounds such as aromatic monocyclic compounds, 1,4-butanediol, glycol ether compounds, and ethylene glycol compounds. The cleaning composition for resin contaminants containing, the aromatic compound, metal sealing agent, alkali metal hydroxide, and the cleaning composition for resin contaminants containing water are disclosed, and the cleaning method of the resin contaminants using the said cleaning composition is disclosed.

Patent document 3 is selected from (a) 2-30 weight% of inorganic alkali agents, (b) anionic surfactant, and nonionic surfactant which has high cleaning power with respect to the high refractive index sulfur-containing plastic lens resin contaminant of refractive index 1.55 or more. 0.5-20 weight% of at least 1 type of surfactant, (c) 0.01-2 weight% of calcium salts [calcium ion conversion], (d) 0.1-15 weight% of calcium ion trapping agents, (e) 1-30 water-soluble organic solvents Disclosed is a cleaning composition containing 20% by weight to 95% by weight of (f) water.

And by using the cleaning composition which concerns on this indication, a high quality plastic lens can be obtained.

It is possible to provide a method for manufacturing a lens. And by using the cleaning composition which concerns on this indication, a high quality plastic lens can be obtained.

Although the detail of the action mechanism of the effect in the cleaning composition concerning this indication is unclear, it is estimated as follows.

The resin for plastic lenses attached to the glass mold is a chemically stable material, and it is difficult to remove the resin from the glass mold by combining the protection of the glass mold and the decomposition of the resin. And the method of peeling is common. In particular, sulfur-containing plastic lens resins that achieve high refractive index tend to be chemically stable and have strong adhesion strength to glass. Accordingly, in order to remove the resin from the glass mold, a method of infiltrating the cleaning agent at the interface between the glass mold and the resin and efficiently peeling the resin from the glass mold by the action of mechanical forces such as stirring and ultrasonic waves is generally used. .

The presence of an inorganic alkali (component B) in the cleaning composition according to the present disclosure promotes cleavage by hydrolysis of ester bonds present slightly in the resin and neutralization of residual acid groups, thereby promoting peeling of the resin from the glass surface. do. On the other hand, the aromatic alcohol (component A) coexists with both the compound (component C) represented by the formula (I) and the compound (component D) represented by the formula (II), and the component A, the component C, and the component D The specific affinity with water, even in a situation where the solubility of component A is lowered due to the presence of component B due to the presence of component B, and the mechanical strength due to agitation or the like is small with respect to component A having low solubility in water, respectively. Can be raised. Therefore, the component A easily penetrates into the interface between the resin attached to the glass mold and the glass mold, and the peeling of the resin from the glass mold is promoted. In addition, since components A-D are specific concentrations, in a long-term repeated washing, the cleaning composition is influenced by accumulation of resin contaminants, absorption of carbon dioxide in the air, volatilization of highly volatile components, deterioration due to local overheating, and the like. Even if it receives, it is estimated that the solubility with respect to the water of component A can be maintained, and high washability can be maintained, without reducing peelability. In addition, by setting the concentration of the component B to 2% by mass or more and 8% by mass or less, excessive corrosion of the glass-like surface can be suppressed while the cleaning property is kept high, and the presence of the components C and D is more advantageous. It is estimated that corrosion of a mold surface can be suppressed. However, the present disclosure is not 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, component F is adsorbed onto the glass-like surface while improving the solubility of the component A in water, It is estimated that corrosion of the glass-like surface by B can be suppressed more.

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 or the following gluconic acid or its salt (component G) forms a calcium salt to form a glass surface. It is estimated that by adsorbing on, the corrosion of the glass-like surface caused by the component B can be further suppressed.

In the cleaning composition according to the present disclosure, when the component G is included as an optional component, the chelating action of the component G and the high solubility of the resulting salt in water, such as calcium due to evaporation of water in long-term use, etc. Precipitation of hardness components is suppressed, and it is estimated that the suppression of the blockage of the piping which circulates the cleaning composition, the prevention of sedimentation of the precipitate, the prevention of adhesion of the precipitate to the glass mold, the cleaning property, and the productivity can be improved.

By the synergistic effect, in one aspect of the cleaning composition according to the present disclosure, workability and operation stability can be improved, and even if repeated cleaning for a long time, the number of times of renewal of the cleaning composition is reduced without degrading the cleaning property. It is estimated that it is possible to reduce, to enable repeated use of the glass type, and to improve the productivity of the high quality plastic lens.
