DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning composition for a plastic lens molded glass mold and a cleaning method using the same. More specifically, various optical plastics such as lenses, prisms, etc. for optical devices such as glasses, cameras, projection televisions, large screens, overhead projectors, compact disc devices, optical memory devices, etc. attached to plastic lens molded glass molds Raw materials for plastic lens molding, unreacted monomers, oligomers, polymers, components bleed out from gaskets, plasticizers, adhesives, adhesives derived from mold fixing tape, etc. The present invention relates to a cleaning composition for a plastic lens molded glass mold for cleaning high molecular weight resinous dirt and the like, and a cleaning method using the same.

[0002]

2. Description of the Related Art In recent years, lenses for glasses, contact lenses, viewfinders for cameras, lenses for photography, lenses for projection televisions, Fresnel lenses for large screens, lenticulars, lenses for condensing sunlight, overhead projector type Fresnel lenses, compact Conversion of glass materials to plastic materials for lenses and prisms for optical devices such as lenses for disks and objective lenses for optical memories is progressing. In particular, lenses for glasses prevent scratches on the surface (hard)
With the development of coating technology and the abrasion resistance at a level that does not pose a practical problem, the development of materials with a high refractive index, and the ability to process thinner and lighter lenses, the conversion of glass to plastic The conversion ratio has increased significantly.

As resins for optical plastic lenses, for example, allyl diglycol carbonate (ADC) resin obtained by radical polymerization of diethylene glycol bisallyl carbonate, urethane resin, sulfur-containing urethane resin, polymethyl methacrylate, styrene/
Methacrylic resins such as methyl methacrylate copolymer, α-methylstyrene / methyl methacrylate copolymer, cyclohexyl methacrylate / methyl methacrylate copolymer, aliphatic methacrylate / methyl methacrylate copolymer, and triazine ring acrylic Acrylic resin such as resin, polycarbonate resin, bromine-containing resin such as bisphenol derivative, olefin resin such as 4-methylpentene-1-fumarate / allyl monomer copolymer, polystyrene, styrene / acrylonitrile copolymer Styrene resin such as coalescence, norbornene resin,
Thioether / ester resins and the like are used.

As a method of manufacturing an optical plastic lens, for example, in the case of a plastic lens for eyeglasses, the plastic lens body is molded using a molded glass mold as a mold, the outer periphery is shaped, and the edge portion is chamfered. Go and be washed.

At this time, the used molded glass mold is washed and used again as a mold. In the case of plastic lenses for eyeglasses, there are thousands of lens types and many kinds and small quantities are produced, so the required molded glass mold is enormous and the manufacturing cost per plastic lens is low. Get higher. Therefore, if one molded glass mold can be used repeatedly,
Since the cost ratio of the molded glass mold in the production of the plastic lens is reduced, the plastic lens can be produced economically and advantageously.

On the other hand, after the plastic lens is released from the mold, the molded glass mold contains plastic lens molding raw materials, unreacted monomers, oligomers, polymers, components bleed out from gaskets, plasticizers, adhesives, and mold fixing tapes. In addition to high-molecular-weight resinous dirt such as pressure-sensitive adhesives, dust in the atmosphere, and fingerprints of workers are attached. If such dirt adheres to the glass mold, a high-quality plastic lens with a smooth surface cannot be obtained, or if the dirt accumulates on the glass mold, the obtained plastic lens may be damaged or damaged. Because of this, the glass mold can no longer be used,
Sometimes they have to be discarded.

Among the stains, high molecular weight resinous stains such as oligomers and polymers derived from raw materials for plastic lens molding, components bleed out from gaskets, adhesives, and adhesives derived from mold fixing tapes are used as glass molds. Is strongly adhered (adhered) to the hard surface, and the resinous dirt itself has a high molecular weight, so that it is very difficult to wash with a chemical utilizing dissolution, swelling, softening, disintegration, peeling action and the like.

Conventionally, for cleaning resinous stains such as oligomers and polymers adhered to a glass mold used in the production of plastic lenses, a cleaning agent containing methylene chloride and a hydrophobic surfactant (Japanese Patent Laid-Open Publication No. 58-119828
And a detergent containing methylene chloride and an aqueous alkaline detergent (JP-A-62-179600).

[0009] Since methylene chloride, which is said to have a low detergency and is also carcinogenic, is used as these detergents, it is desirable to avoid using them.

In recent years, as a cleaning agent for a plastic lens molded glass mold, for example, a cleaning agent using a specific glycol diether (JP-A-8-224740),
Detergents containing a specific water-soluble amide compound or water-soluble lactone compound, an alkanolamine or a quaternary ammonium hydroxy compound, an aromatic hydrocarbon and water (JP-A-9-3486) are known. ing.

[0011] However, since these cleaning agents are mainly cleaning mechanisms for dissolving and cleaning resinous dirt, if the molecular weight of the resinous dirt is large, it takes a long time to dissolve. is there.

In addition to the above-mentioned cleaning agents, an alkaline cleaning agent that mainly removes contaminants, that is, removes adhered dirt, has a detergency when the amount of contained inorganic alkali is small. And it takes a long time to completely remove the dirt, or the dirt must be removed manually. In addition, when the amount of the inorganic alkali is increased in order to provide a sufficient detergency, corrosion such as so-called latent damage or burning occurs on the surface of the glass mold. When corrosion occurs on the glass surface in this way, a high-quality plastic lens having a smooth surface cannot be obtained, and the glass mold must be polished and surface-reinforced again, or in some cases, the glass mold must be discarded. There is a problem that it becomes extremely uneconomical.

Therefore, as a cleaning agent for glass that hardly damages the glass surface, for example, a cleaning agent using a quaternary ammonium hydroxide base, a nonionic surfactant and an alkanolamine (Japanese Patent Laid-Open Publication No. Hei. 27169
No. 9) and a detergent using water glass as a builder (Japanese Patent Application Laid-Open No. 9-71799) has been proposed.
However, these cleaning agents do not cause much damage to the glass surface, but have the drawback that the surface is roughened while the glass mold is used repeatedly.

Further, a detergent using an inorganic alkali base and a calcium ion-releasing substance or a calcium complex has been proposed (JP-A-61-157595). However, such a cleaning agent has a drawback that cleaning properties against high molecular weight resinous dirt are insufficient.

[0015]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned prior art, and has excellent cleaning properties against high-molecular-weight resinous dirt and safety against the human body at the time of cleaning. It is an object of the present invention to provide a detergent composition for a plastic lens molded glass mold that does not use the same.

Another object of the present invention is to provide a cleaning method which is excellent in detergency for high molecular weight resinous dirt and human body at the time of cleaning, and which can be cleaned without corroding a molded glass mold. And
