Embodiment 1

[0034] The main components of environmentally friendly PS plate ink and photosensitive adhesive stripping agent are 1.2% by weight of organic surfactants, 1.2% of inorganic surfactants, 14% of organic solvents, 7% of acids, and the rest is water. Specific preparation The method is as follows: add 1200 kg of water to a 1500-liter water tank, then add 15 kg of alkylphenol polyoxyethylene ether and 15 kg of disodium hydrogen phosphate into the water tank, stir evenly, then add 100 kg of phosphoric acid and 175 kg of ethylene glycol, and mix well Stir for 2-3 hours to get evenly mixed environment-friendly PS plate ink and photosensitive adhesive stripping agent. 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 the large tank, then put the PS plate to be strip...

Embodiment 2

[0036] The main components of environmentally friendly PS plate ink and photosensitive adhesive stripping agent are 0.5% by weight of organic surfactants, 2% of inorganic surfactants, 10% of organic solvents, 3% of acids, and the rest is water. Specific preparation The method is as follows: add 400 kg of water to an 800-liter water tank, add 2.5 kg of fatty alcohol polyoxyethylene ether and 10 kg of sodium tripolyphosphate into the water tank at room temperature, stir evenly at room temperature, then add 15 kg of sulfuric acid and 50 kg of Ethanol, stirring for 2-3 hours, just get the environment-friendly PS printing ink and photosensitive adhesive stripping agent. Use the continuous stripping method of environmentally friendly PS plate ink and photosensitive adhesive stripping agent to peel off the environmentally friendly PS plate ink and photosensitive adhesive stripping agent. The PS plate to be stripped is continuously placed on the continuously rotating stripping producti...

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 kg of pentaerythritol, kept at room temperature and stirred for 2-3 hours, can be mixed evenly with environmentally friendly PS plate ink and photosensitive adhesive stripping agent. Use environmentally friendly PS plate ink and photosensitive adhesive stripping agent intermittent stripping method for PS plate Stripping of ink and photosensitive adhesive. Put the environmentally friendly PS plate ink and photosensitive adhesive stripper in the large ta...

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, photosensitive adhesive stripping agent and preparation method thereof for regeneration of environment-friendly PS plates. Background technique [0002] my country's printing industry has formed a printing method based on offset printing through research and development and the introduction of technology. At present, except for a small amount of zinc oxide paper-based plates for light printing, most of the plates used in offset printing are PS plates based on metal aluminum plates. my country's PS plate 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 plates consumes a large amount of metal aluminum. According to statistics, our country now uses 130-140 million square meters of PS plates every year, and needs to consume more than 100,000 tons of metal alumi...
