[0035] In the above examples, all raw materials can be purchased from the market, or prepared with reference to the preparation examples disclosed in the present invention.

[0036] Wherein: the preparation and use method of vinyl acetate-acrylate copolymer emulsion:

[0037] (1) Add deionized water, alkylphenol polyoxyethylene ether and polyvinyl pyrrolidone into the enamel kettle with stirrer and reflux condenser, then slowly raise the temperature to about 40°C, and stir well. (2) Add about 1 / 5 of the total amount of mixed monomers (vinyl acetate, butyl acrylate and 2-ethylhexyl acrylate) into the reactor, and then add about 1 / 3 of the total amount of ammonium persulfate with water Add it to the reaction kettle after melting, and divide the remaining ammonium persulfate into 5 parts. Except one part is added at the end, the remaining four parts are added to the reaction kettle every 40 minutes. (3) Raise the temperature of the material in the reactor to 68-72°C,...

Abstract

The invention discloses a new polymer blue-ray engraving material, which consists of aqueous solution of modified SBQ (special bar quality) resin, epoxy resin, a curing agent, a photo polymerization initiator and the like. Organosilicon modified polyurethane is adopted to generate synergy with a colloid, and the acid and alkali resistance of a film is improved; and vinyl acetate and acrylate copolymer is introduced and is coordinated with long-chain ester monomers, multi-functional active monomers and modified polyurethane to form an interpenetrating network/semi-interpenetrating network, so that the mechanical properties of the film are obviously improved, the chemical resistance and mechanical wear resistance of photoresists are improved and the adhesion of the photoresists to a base material is improved. Without action of chromium ions, the new polymer blue-ray engraving material has high photosensitivity to blue-ray laser dotting instant exposure, good cross-linking curing performance, and the water development fastness meeting the engraving requirement, has good printing fastness after high-temperature curing, and has good application prospect.

Description

technical field [0001] The invention relates to a new polymer blue-ray plate-making material suitable for blue-ray plate-making. Background technique [0002] Since the advent of the rotary screen plate-making photosensitive adhesive for decades, the rotary screen plate-making photosensitive adhesive has always been a dichromate photosensitive emulsion colloid, and the two components are packaged separately. Obviously, the toxicity of chromium ions has brought difficulties to the discharge of the developer. . Entering the 21st century, human beings attach importance to the living environment and seek sustainable development, and do not want to use dichromate / PVA photosensitive system. [0003] Invention patent application: a water-resistant and environment-friendly rotary screen plate-making photosensitive adhesive. The modified SBQ resin and resin curing agent are used in the publication number CN101241304A. After continuous baking for 360 hours at a temperature between 5...
