Definitions
- the present invention relates to a photo-curing adhesive which cures by irradiating active energy rays such as ultraviolet rays or visible rays to exhibit excellent adhesive strength, and more particularly to the bonding of glass, ceramics and the like.
- the present invention relates to a photocurable adhesive having good water resistance and moisture resistance when used, and excellent low-temperature durability and heat shock resistance.
- Conventional photocurable adhesives include so-called epoxy (meth) acrylates having (meth) acrylate groups at both ends of the bisphenol A skeleton, and isophorone diisocyanate.
- a monomer composition obtained by mixing a low-viscosity monomer called a reactive diluent such as acrylate and a small amount of a photopolymerization initiator has been used.
- photo-curable adhesives are widely used because they have the following advantages over solvent-dilutable adhesives and heat-curable adhesives that have been used for a long time.
- the photo-curing adhesive basically does not contain a solvent that does not participate in the bonding, there is a danger in the bonding operation due to the evaporation of a larger amount of solvent and a significant volume shrinkage compared to the conventional solvent-volatile adhesive. Almost no adhesion loss due to the above.
- light-curable adhesives can provide practical adhesive properties by irradiating light for several seconds to several minutes, which means that conventional heat-curable adhesives require heating operations for several hours to tens of hours. Adhesion operation is remarkably speedy, and a large amount of heat energy is consumed by the heating operation, and there is almost no damage to the adherend such as thermal deterioration.

- the adhesive strength is only about one-tenth or less of that of the conventional adhesive, and there is a problem in the operability and reliability of the adhesive, which is not practical.
- Photocurable adhesives using radical-reactive silicone oligomers can be photocured, but have poor adhesive strength, similar to RTV rubber. For this reason, even if there is no problem at a low temperature of about 20 ° C below tens of degrees, if the temperature is lower than that, there is a defect that the adhered material easily peels off, and the low-temperature characteristics of the adhesion become insufficient. However, the reliability is poor, such as peeling when a sudden temperature change is applied, and the problem of the conventional technology has not been solved.
