Embodiment 1

[0034] The weight percentage of the main components of environmentally friendly PS plate ink and photosensitive adhesive stripper is 1.2% of organic surfactant, 1.2% of inorganic surfactant, 14% of organic solvent, 7% of acid, and the rest is water. The method is as follows: add 1200 kilograms of water in a 1500-liter water tank, then add 15 kilograms of alkylphenol polyoxyethylene ether and 15 kilograms of disodium hydrogen phosphate into the water tank, stir evenly, and then add 100 kilograms of phosphoric acid and 175 kilograms of ethylene glycol, evenly After stirring for 2-3 hours, a well-mixed environment-friendly PS plate ink and photosensitive adhesive release agent are obtained. The PS plate ink and photosensitive adhesive are peeled off by the intermittent peeling method of environmentally friendly PS plate ink and photosensitive adhesive stripper. Put the environmentally friendly PS plate ink and photosensitive adhesive stripper in the large tank, then put the PS pl...

Embodiment 2

[0036] The weight percentage of the main components of environmentally friendly PS plate ink and photosensitive adhesive stripper is 0.5% of organic surfactant, 2% of inorganic surfactant, 10% of organic solvent, 3% of acid, and the rest is water. The method is as follows: add 400 kilograms of water to an 800-liter water tank, add 2.5 kilograms of fatty alcohol polyoxyethylene ether and 10 kilograms of sodium tripolyphosphate into the water tank at room temperature, stir evenly at room temperature, and then add 15 kilograms of sulfuric acid and 50 kilograms of Ethanol, stirring for 2-3 hours, then the environmentally friendly PS printing ink and photosensitive adhesive stripping agent are obtained. The environmentally friendly PS plate ink and photosensitive adhesive stripping agent are used for continuous stripping method to carry out the stripping of environmentally friendly PS plate ink and photosensitive adhesive stripping agent. Spray on the PS plate, usually after 2-6 mi...

Embodiment 3

[0038]The main components of environmentally friendly PS plate ink and photosensitive adhesive stripping agent are 2% by weight of organic surfactant, 0.5% of inorganic surfactant, 20% of organic solvent, 15% of acid, and the rest is water. Specific preparation The method is as follows: Add 400 kg of water into an 800-liter water tank, add 10 kg of polyoxyethylene sorbitan monooleate and 2.5 kg of dipotassium hydrogen phosphate into the water tank at room temperature, stir to fully dissolve, and then add 75 kg Oxalic acid and 100 kilograms of pentaerythritol are kept at room temperature and stirred for 2-3 hours to obtain evenly mixed environment-friendly PS plate ink and photosensitive adhesive stripper. The environmentally friendly PS plate ink and photosensitive adhesive stripping agent intermittent stripping method is used to peel off the PS plate ink and photosensitive adhesive. Put the environmentally friendly PS plate ink and photosensitive adhesive stripping agent in t...

Abstract

This invention provides a environment protective PS plate printing ink and photoresist remover, which features the composition of 0.5-2 % (by weight) of organic surface active agent, 0.5-2 % of inorganic surface active agent, 10-25 % of organic solvent, 3-15 % of acids, the others is water. Said invention also provides relative preparation and use method.

Description

technical field [0001] The invention relates to the regeneration of PS plates, in particular to an ink and a photosensitive adhesive stripper used for the regeneration of environment-friendly PS plates and a preparation method thereof. Background technique [0002] my country's printing industry has formed a printing method mainly based on offset printing through research and development and introduction of technology. At present, most of the plates used in offset printing are PS plates based on metal aluminum plates, except for a small amount of zinc oxide paper-based plates for light printing. my country's PS version has developed rapidly, and the output in 2004 has exceeded 100 million square meters, accounting for more than 20% of the world's total output. The production of PS version consumes a lot of metal aluminum. According to statistics, my country now uses 130-140 million square meters of PS plates every year, and needs to consume more than 100,000 tons of metal ...
