    专利说明:

    The invention relates to methods for gluing optical components, such as frames, used in the field of optical-mechanical industry.
    Epoxy-based adhesive compositions in combination with methacrylates are known, which are cured by UV irradiation. (UK patent Vf 1552046, class B 5 N, 1979), based on 2-hydroxy-3-chloropropylacrylate or methacrylate and polymerizing vinyl monomers (Japanese Patent No. 53-19351, class C 09 J 3/14, 1978). Adhesives do not provide glass compounds with high weather resistance.
    A known method for producing cold-setting adhesives consists in the light polymerization of mixtures of polythiols containing at least two thiol groups in the molecule and polyenes with two reactive unsaturated carbon-carbon bonds in the presence of photoinitiators (HGF no. 2734076, cl. C 08 L 59/00, 1977). The adhesive is used in the bonding of glass, providing a form-stable, solvent-resistant compound. However, gluing the glass with this glue does not ensure sufficient weather resistance of the joint.

    As photosensitizers employed are benzophenone, thioxanthone or triphenylphosphine, and as photoinitiators - diaryliodonium salts, particularly tetrafluoroborat ditiolilyodoni, geksafluoroantimon ditiolilyodoni, geksafluorofosfat ditiolilyodoni or geksafluoroar- Senate ditiolilyodoni.
    The optical glue used in photoplastic two stages has the composition of monomers and initiators, which allows the additive to carry out additive polymerization and polymerization with chain growth from the liquid mixture of monomers in two independently controlled reaction phases: in the polyaddition of dithiol to the diene component and in the diaryl iodonium solids initiated mi cationic polymerization with epoxide ring opening.
    Hydroxyacrylates can be added to equimolar mixtures of dithiol and diene compound, thereby achieving rapid photofixation.
    If a photo-curing thiol-ene additive system requires step-by-step photo cure, instead of hydroxyacrylates (methacrylates), additional epoxides are added with at least two epoxy groups and 0.5-5% by weight of photo initiators of diaryl iodonium salts relative to the amount of epoxides used. In this case, the adhesive mixture is normally supplied between the glued optical parts and is precisely adjusted optically. In this state, it is irradiated with filtered light of a high-pressure mercury lamp (36 O nm) for 1-2 minutes, at which time optical components are fixed. After that, optical details

    whether without additional attachment can be subjected to storage and transport. Erroneously glued optical components can be easily separated and cleaned with organic solvents (chloroform, acetone) by brief heating to 80-120 ° C. Then they are again able to use. If correction of glued optical parts is not required, they are irradiated once again for 5 to 10 minutes with uncleaned light of a high-pressure mercury lamp to achieve final curing, after which the optical parts are capable of being used.
    The diene-dithiol polymerization system with monomers — epoxides or hydroxyacrylates (methacrylates) with at least one functional hydroxyl group or with epoxides and hydroxyacrylates (methacrylates) —and in combination with known photoinitiators gives glue that binds technological workability with good properties . For a photoinitiated start of the curing process in a one or two step bonding process, a minimum irradiation time is required (up to seconds). Poor adhesion in the two-step curing process can be corrected after the first cure stage (fixation step). At the same time, durable, weather-resistant, elastic gluing with low voltage is achieved.
    Example 1. In a mixture of 2 g of diglycol bisallyl carbonate, 1.823 g of triglycol dithiol and 6.8 mg of benzofenonone, 0.90 g of an acrylic acid adduct to bisphenol-diglycidyl ether is dissolved. Then, a colorless solution, as usual, is fed between the optical components to be bonded and is subjected to a high pressure mercury lamp. Fixation is carried out for 30 seconds of irradiation, after which the optical parts are capable of being used.
    Example2. In a mixture of 2, g of diglycol bisallyl carbonate, 4.125 g of dianol ester and thioglycolic acid and 0.1 g of benzophenone, g of acrylic 3-chloro-2-hydroxypropyl ester are dissolved. Colorless low viscosity solution is used for

    Example In a mixture of 2 g of diglycol bisallyl carbonate, 1.823 g of triglycol dithiol and 6.8 mg of benzofenonone, 1.0 g of bisphenol-A-diglycidiyl ether and 5 mg of dithiolyl iodonium tetrafluoroboroboride are dissolved with moderate heating. The solution is fed between the optical components being bonded and irradiated with light (metallic interference filter) of a high-pressure mercury lamp (wavelength of 365 nm). After 60 s, the optical components are fixed. In case of wrong gluing, a thermal connector is possible by briefly heating up to 90 ° C. The final bonding is performed by repeated irradiation with unfiltered light of a high pressure mercury lamp for 5 minutes. After that, optical parts are capable of use.
    Example. In a mixture of 2.76 g of phoron, 3.65 g of triglycol dithiol and 0.9 g of thioxanthone, t, 0 g of bis-phenol-A-diglycidyl ether and 5 mg of dithiol-iodonium hexafluoroantimonate are dissolved, then, as in Example 3, irradiation is performed in kQ s for fixing and 5 minutes for final gluing.
    The spectral transparency of the proposed adhesive compound is 300-700 nm. In addition, 50% of the bonded optical parts are weather resistant from 20 to 70 ° C (humid warm variable climate), and the cut-off transparency of the resulting compound is 0-63 kgf versus 18 kgf when using a known adhesive.
