Abstract

The invention discloses an ultraviolet curable adhesive with high light transmittance. The ultraviolet curable adhesive provided by the invention is prepared from the following raw materials of: by weight, 5.8-59% of modified acrylic acid oligomer resin, 5.8-59% of an acrylic acid monomer, 2-10% of an auxiliary agent, 0.5-15% of a silane coupling agent, and 1.5-10.5% of a photoinitiator. With the adoption of the above components in proportions, the adhesive provided by the invention has fast curing rate and excellent optical properties, the glue solution is colorless and transparent, its light transmittance after curing is greater than 95%, cure shrinkage is small, the internal stress is low, and caking capability is strong.

Description

technical field [0001] The invention relates to an ultraviolet (UV) curable adhesive, in particular to an ultraviolet (UV) curable adhesive with high light transmittance, which can be used for bonding glass to glass. Background technique [0002] Ultraviolet (UV) is invisible to the naked eye, and is a section of electromagnetic radiation other than visible light, with a wavelength in the range of 10-400nm. Ultraviolet (UV) curing adhesive refers to a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive or as a glue for paints, coatings, inks, etc. The principle of UV glue curing is: the photoinitiator (or photosensitizer) in the UV curing material absorbs ultraviolet light to generate active free radicals or cations under the irradiation of ultraviolet light, triggering chemical reactions of monomer polymerization, crosslinking and grafting, so that The adhesive changes from liquid to solid within seconds. The existing ultraviolet curing...
