Abstract

The invention discloses a photocuring adhesive used for adhering optic glass lenses, which consists of the following components in percentages by weight: 50-80% of main resin, 10-40% of auxiliary resin, 5-20% of active monomer, 4-4.5% of photo initiator and 0.5-1% of auxiliary. The main resin is alicyclic epoxy resin. The auxiliary resin is modified epoxy acrylate resin. The active monomer is oneor a mixture of vinyl ether monomers and acrylate monomers. The photo initiator is a radical photo initiator and a cation photo initiator. The auxiliary is a coupling agent. The photocuring optic adhesive has the characteristics of high curing speed, high refraction rate, high light transmittance, low curing shrinkage rate, small thermal deformation, strong adhesion force, small smell, yellowing resistance and the like.

Description

technical field [0001] The invention relates to an adhesive used for optical glass, in particular to an optical adhesive cured by ultraviolet light or visible light and a preparation method thereof. Background technique [0002] Optical transparent adhesives are used in the optical field, so they must meet some basic requirements, such as: colorless and transparent; the light transmittance in the specified light wave band is greater than 90%; and the refractive index of the adhesive after curing is the same as that of the optical components to be bonded The refractive index is similar; the bonding strength of the adhesive is good in the temperature range of use; the modulus of the adhesive is low, the elongation after curing is large and the curing shrinkage is small, and the change of the surface of the optical element will not be caused; the hygroscopicity is small, and the resistance to cold and heat shock , Vibration resistance, oil resistance, solvent resistance, light ...
