A preparation method and application method of light-curing screen printing photosensitive adhesive

Abstract

The invention discloses a light-cured silk-screen printing photosensitive glue. According to a preparation method of the light-cured silk-screen printing photosensitive glue, acrylamide monomer is added, so that sensitivity and developing film remaining ratio are high, practical production demands are satisfied, and glue membrane of a screen printing plate prepared from the light-cured silk-screen printing photosensitive glue is easy to wash, and no residue is left. According to an application method, a nylon silk screen is degreased, washed and dried, and screen cloth is coated with the light-cured silk-screen printing photosensitive glue in a place without perpendicular incidence of sunlight so as to obtain the screen printing plate; a printing surface and a glue shaving surface are coated for one time respectively, the screen printing plate is completely dried in a dryer with a temperature of 45 DEG C, the printing surface is coated for two times, and the screen printing plate is dried again; and the dried screen printing plate is subjected to exposure for 120s using a high pressure mercury lamp, is allowed to stand for 5min in an environment without light, is immersed in water for 2min, and is washed with water so as to develop, wherein when the dried screen printing plate is subjected to exposure, the screen printing plate is firmly pressed against a positive image bottom plate.

Description

technical field [0001] The invention relates to a screen printing photosensitive adhesive, in particular to a method for preparing and using a photocurable screen printing photosensitive adhesive. Background technique [0002] Screen printing has made considerable progress because it is suitable for various shapes of substrate materials, various types of inks, and flexible and diverse printing methods. However, the domestic screen printing plate-making industry has developed for decades, and it is still dominated by diazo photosensitive adhesives. Nitrogen photosensitive glue has ideal photosensitivity, plate making and resolution, but its thermal stability is not good, the glue solution has a short storage time, and the coated screen is prone to dark reaction and the development is not clean. The SBQ photosensitive glue launched by Murakami has excellent performance, but the synthesis process is complicated and expensive. The photopolymerization system has the characterist...
