Abstract

The invention discloses a transfer processing method for a glass base material of a cover board. The transfer processing method comprises the following steps: coating the surface of the glass base material of the cover board with an LED photo-curable non-solvent photosensitive transfer adhesive; covering a film diaphragm; carrying out a procuring exposure with an LED light source at a low energy of 100-200mJ / cm<2>; removing the film diaphragm, and dissolving an unexposed part adhesive with a developing solution; blowing or drying residual developing solution; and finally carrying out secondary curing on the developed transfer adhesive with the LED light source at a high energy of 1,000-2,000mJ / cm<2>, thereby finishing transfer processing of the glass base material of the cover board. According to the technology disclosed by the invention, the problems that an existing UV adhesive is poor in adhesion to glass of the cover board, poor in boiling resistance and poor in solvent resistance are solved; the industry requirements are met; the production cost of enterprises is reduced; and the benefits of the enterprises are improved.

Description

technical field [0001] The invention relates to the technical field of photocuring transfer printing, in particular to a method for treating a cover glass substrate with an LED photocuring solvent-free photosensitive transfer adhesive. Background technique [0002] In order to improve the grade of the product, surface decoration is essential, and the use of transfer printing technology can improve the decoration level of the product surface. The traditional UV transfer adhesive is mainly a light-curing one-component molding dispensing glue, which is formed on the surface of plastic film substrates such as polycarbonate, polyethylene terephthalate and thermoplastic elastic polyurethane through molds. When using UV transfer adhesive for traditional plastic substrates in mass production, there are often problems of overflowing glue on the edge of the material and excessive film thickness. By cutting off the bad parts, a high production yield can be ensured. The cover glass sub...
