A kind of ultraviolet curable adhesive and its preparation method and application

Abstract

The invention provides an ultraviolet curing adhesive, a preparation method and application thereof. The raw materials for the preparation of the UV-curable adhesive include the following components in parts by weight: 30-55 parts of acrylic oligomers, 5-20 parts of epoxy-modified acrylic oligomers, and 30-50 parts of reactive diluents , 0.5-3 parts of silane coupling agent, 2-5 parts of photoinitiator and 0.2-1 part of colorant; the acrylic oligomer includes polyether urethane methacrylate and / or urethane acrylate. The UV-curable adhesive of the present invention has suitable glue film hardness, superior acid and alkali resistance and mechanical properties, can make the glass thinner and thicker, and is convenient for glue removal, simple in preparation process and good in stability.

Description

A kind of UV-curable adhesive and its preparation method and application technical field The invention belongs to the field of liquid crystal adhesive, be specifically related to a kind of ultraviolet curing adhesive and preparation method thereof and application. Background technique [0002] In recent years, display devices have been developed in the direction of lightness, thinness and power saving. As a liquid crystal display, thin film transistors Liquid crystal display (TFT‑LCD) is one of the widely used flat panel displays, featuring low power consumption, thin profile, light weight, etc. feature. With the development of LCD technology, desktop LCD monitors, notebook monitors, smart phones and large-size LCD TVs are becoming more and more More and more popular, in order to cope with the development trend of thinning of various liquid crystal displays, the production line has been invested in the thinning of products. in production. In the process of thinning...

AI Technical Summary

Problems solved by technology

The adhesive uses a composite system of epoxy resin and urethane acrylate, which also has a strong sealing ability, but it still cannot meet the needs of lighter and thinner display devices, and the alkali resistance needs to be improved
