UV-STRENGTHENING GLUE COMPOSITION, OPTICAL READING HEAD WITH ITS USING AND OPTICAL RECORDING/REPRODUCING DEVICE COMPRISING OPTICAL READING HEAD

FIELD: glue compositions. ^ SUBSTANCE: invention relates to UV-strengthening glue compositions used for gluing substrates metal-silicate glass in electronic devices, such as optical reading head, thin-film transistor - semiconducting mesomorphic display, organic luminescent unit. The composition comprises oligourethaneacrylate - a mixture of oligourethaneacrylates of two type: the first is prepared by interaction of oligooxyalkylenepolyol of molecular mass 1000-5000 Da, diisocyanate of aliphatic or aromatic structure and alkylene glycol monomethacrylate, and the second based on oligobutadienediol of molecular mass 2000-3000 Da, diisocyanate of aliphatic or aromatic structure and alkylene glycol monomethacrylate in the mass ratio of the first to the second = (1.0-4.0):1, reactive monomer as a diluting agent, silicate filling agent, organic tert.-butylperbenzoate, thixotropic agent - aerosil and photoinitiating agent, and, additionally, it comprises oxalic acid as adhesion promoter, silane dressing agent and antioxidant of phenolic type. Invention provides the development of UV-strengthening glue composition possessing thixotropy, high strengthening rate, high adhesion strength being especially at effect of heat and moisture, temperature drop, low shrinkage and stability in storage. ^ EFFECT: improved and valuable properties of composition. ^ 7 cl, 2 tbl, 5 dwg, 8 ex
