DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to 1,1,2-trichloro-1,2,2-trifluoroethane (hereinafter referred to as CFC).
113), a mold release agent composition for a plastic mold not using an organic chlorine-based solvent, and
The present invention relates to a plastic lens and an inkjet component molded using the same.

2. Description of the Related Art Release agents for plastic molds are classified into inexpensive silicone release agents and fluorine release agents which are expensive but have good secondary workability. Of these, the latter fluorine-based release agents are currently the mainstream of plastic mold release agents due to the fact that they require a small amount of use, less mold contamination, and less migration to molded products. I have.

The effective main components of these fluorine-based release agents are
In many cases, it is composed of a fluorinated oil, a fluorinated resin, a fluorinated surfactant, and the like. If necessary, a silicone oil, a binder resin, or the like is added and diluted with a chlorofluorocarbon such as CFC113 (hereinafter abbreviated as CFC). Things. These CFCs have an appropriate solubility in the organic fluorine compound as a main component, have an appropriate boiling point for volatilization, have low toxicity to the human body, and are nonflammable. Therefore, it has been used as a solvent.

[0004] Ozone holes have been discovered in recent years due to unusual changes in the global environment, and it has become clear that the main cause thereof is organochlorine compounds. CFCs, which are particularly chemically stable, have a long life in the troposphere and diffuse to reach the stratosphere, where they are photolyzed by sunlight to generate chlorine radicals. These chlorine radicals combine with ozone and destroy the ozone layer. For this reason, the use of organic chlorine compounds such as CFCs is internationally restricted or prohibited.

As an alternative to CFC, 1,1-dichloro-2,2,2-trifluoroethane (hereinafter referred to as HCF)
C123), 1-fluoro-1,1, dichloroethane (hereinafter abbreviated as HCFC141b), 1,1-dichloro-2,2,3,3,3-pentafluoropropane (hereinafter abbreviated as HCFC225ca), 1 And hydrochlorofluorocarbons (hereinafter abbreviated as HCHF) such as 3-dichloro-1,1,2,2,3-pentafluoropropane (hereinafter abbreviated as HCFC225cb) have been developed and partially commercialized. Some HCFCs have ozone depletion potentials that are not negligible compared to conventional CFCs, and international reduction schedules similar to CFCs are beginning to be formulated.

As an alternative solvent to CFC and HCFC, the present inventors have focused on low chemical attack and nonflammability of perfluorinated organic compounds, and have proposed various nonflammable compositions. (JP-A-5-214324, JP-A-7-53996, JP-A-8-9260)
No. 0).

Further, with respect to the release agent composition, see
A proposal is made in -109158. In this release agent composition, the active ingredient is composed only of the fluorine oil, and although the paintability, the release force, etc. are sufficient, sufficient satisfaction was not obtained in terms of the sustainability of the release force. .

The present invention focuses on this point, and provides a non-flammable and highly safe plastic mold which has sufficient durability of the releasing force and does not use an organic chlorine-based solvent such as CFC or HCFC.
