Abstract

The invention relates to a UV (ultraviolet) curing adhesive stripper, a preparation method thereof and an adhesive stripping method. The adhesive stripper contains 40%-50% of organic ketone, 0.5%-1.0% of organic quaternary ammonium base compound, 0.1%-0.5% of surfactant and the balance of pure water. The adhesive stripper can be used for stripping most of UV curing adhesive attached to a glass substrate, the remaining trace of UV curing adhesive is attached to stripped glass substrates and the UV curing adhesive can be thoroughly stripped with a small amount of concentrated sulfuric acid and hydrogen peroxide. By virtue of the UV curing adhesive, the use amount of a concentrated sulfuric acid solution and hydrogen peroxide can be respectively reduced by 80%-90%, and the adhesive stripping cost can be decreased. Besides, the preparation technology of the adhesive stripper is simple and easy to operate and the adhesive stripper can be used repeatedly.

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...
