Abstract

The invention provides an ultraviolet curing epoxy adhesive and a preparation method and application thereof. The ultraviolet curing epoxy adhesive is prepared from the following raw materials in parts by weight: 30-60 parts of basic epoxy resin, 20-30 parts of toughened epoxy resin, 10-30 parts of an epoxy diluent, 1-5 parts of a photoinitiator and 1-10 parts of an auxiliary agent, wherein the basic epoxy resin, the toughened epoxy resin and the epoxy diluent all have symmetrical molecular structures. By adding the basic epoxy resin, the toughening epoxy resin and the epoxy diluent which are symmetrical in molecular structure, the prepared ultraviolet curing epoxy adhesive can resist high-concentration acid-base etching liquid, is easy to trim and tear when used as UV glass edge sealing adhesive, is free of solvent addition in the preparation process, and meets the environment-friendly requirement; and the viscosity of the adhesive can be adjusted according to actual requirements.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to a UV-curable epoxy adhesive and its preparation method and application, in particular to a UV-curable epoxy adhesive with high acid and alkali resistance and good toughness, its preparation method and application. Background technique [0002] The Flat Panel Display (FPD) industry covers applications such as computers, TVs, smart phones, automotive displays, commercial displays, medical health, and smart wear, and the market demand is very large. With the development of flat panel display technology and the improvement of the quality of life, people's requirements for display technology are also constantly increasing. As an important basic material for FPD, glass substrates are also developing rapidly in fine processing technology to meet market demand. Based on the purpose of reducing costs and improving image quality, the thinning of FPD photoelectric glass can meet these requ...
