More Information
Summary:The invention discloses a single-liquid type electronic paper edge sealing adhesive capable of being repaired. The single-liquid type electronic paper edge sealing adhesive comprises the following components in parts by weight: 25-65 parts of hyperbranched epoxy resin, 10-35 parts of epoxy resin, 5-15 parts of a flexibilizer, 10-25 parts of a diluent and 15-30 parts of a curing agent. The method for preparing the hyperbranched epoxy resin through thiol-olefin click reaction is efficient, rapid, environmentally friendly and free of by-products, the problems of tedious process, pollution and the like in traditional epoxy resin synthesis are solved, the hyperbranched structure epoxy resin has lower viscosity, better fluidity is provided for electronic paper edge sealing glue, and the production efficiency is improved; on the other hand, hydroxyl is not contained, so that the water resistance of the formula is also greatly improved; the hyperbranched epoxy resin prepared through thiol-olefin click reaction contai
