Abstract

The invention provides a high-transmittance adhesive. The high-transmittance adhesive is prepared from the following components in parts by weight: 50 to 100 parts of epoxy resin, 30 to 120 parts of carboxyl-terminated hyperbranched polyester, 5 to 100 parts of a quaternary thiol type compound, 50 to 150 parts of a solvent and 1 to 10 parts of a catalyst. The invention further provides a preparation method of the adhesive. After the high-transmittance adhesive is coated with a film, the high-transmittance adhesive has a rapid curing capability, a good light transmission property and a good adhesion property; the high-transmittance adhesive can be applied to adhesion of optical instruments including microscopes, telescopes, projectors, range finders and the like and materials including ITO (Indium Tin Oxide) glass, mobile phone glass, tempered glass windows and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to an adhesive, in particular to a high-permeability adhesive and a preparation method thereof. Background technique [0002] Colorless transparent adhesives are often used for bonding transparent materials due to their excellent light transmittance, such as the bonding of rangefinders, altimeters, telescopes, microscopes, projector lenses, and magnifying glasses. wind glass. Therefore, colorless and transparent epoxy adhesives have very broad development prospects, and the research on colorless and transparent epoxy adhesives has become a hot spot in research. Epoxy resins commonly used in colorless and transparent epoxy adhesives, as well as curing agents, accelerators, tougheners, diluents and other additives should be colorless and transparent, so its main component is generally colorless and transparent epoxy resin Such as E-51, E-54, CGY-331, etc. and colorless and transpare...
