Abstract

The invention relates to a degumming agent for UV curable glue, a preparation method and a degumming method thereof. The degumming agent of the UV curing adhesive contains 40%-50% of organic ketones, 0.5%-1.0% of organic quaternary ammonium base compounds, 0.1%-0.5% of surfactants, and the balance of pure water. Using the debonding agent of the present invention can take off most of the UV curing glue bonded in the glass substrate, and a small amount of UV curing glue adheres to the peeled glass substrate, and a small amount of concentrated sulfuric acid and hydrogen peroxide can be used to treat the UV curing glue. Perform a thorough degumming. Using the UV curing adhesive degumming agent of the present invention can reduce the consumption of concentrated sulfuric acid solution by 80% to 90%, reduce the consumption of hydrogen peroxide by 80% to 90%, and reduce the degumming cost. At the same time, the preparation process of the UV curing adhesive degumming agent of the present invention is simple, Easy to operate and can be recycled many times.

Description

technical field [0001] The invention relates to a degumming agent for UV curable adhesive, a preparation method and a degumming method thereof, in particular to a degumming agent for UV curable adhesive bonded glass substrates, a preparation method and a degumming method. Background technique [0002] As an economical, efficient, ecological, energy, and multifunctional adhesive, UV curing adhesive is widely used in many fields such as the manufacture of printed circuit boards, various plastic bonding, liquid crystal display installation, and electronic glass bonding. At present, concentrated sulfuric acid is mainly used as a debonding agent for UV curing adhesive bonding glass substrates. UV curing adhesive bonding glass substrates are soaked in hot concentrated sulfuric acid to completely carbonize the UV curing adhesive, and then add hydrogen peroxide solution to it. After carbonization, the concentrated sulfuric acid solution is decolorized and bleached, and the glass sub...
