Abstract
The present invention provides a PS plate regeneration peeling solution capable of peeling a picture pattern layer on a PS plate, namely an unexposed photosensitive resin-m-methylphenol-formaldehyde resin type polymer. The PS type regeneration peeling solution has the advantages of simple preparation, low price, circulation use, no environment pollution. The peeled PS plate can be regenerated and reused, and has the printability same with a new PS plate manufactured in the same technology. With the PS plate regeneration peeling solution of the present invention, the picture pattern layer can be peeled in five to ten seconds under normal temperature and pressure by light mechanical friction (mechanical or manual operation). Serial products of the present invention can be also used as PS plate retouching solutions.
Description
What the present invention relates to is a series of photosensitive resin strippers, be specially adapted to peel off positive PS printing plate (aluminium base flat stamping presensitized plate) figure lamina composition-metacresol formaldehyde resin photopolymer and do not damage aluminum substrate Grains layer, the PS version is regenerated, reuse.
At present, domestic having peeled off PS domain lamina with the concentrated sulphuric acid, but its corrosivity is stronger, and to human body, equipment and environmental hazard are bigger.Also useful abroad hydrofluorite adds cyclohexanone as stripper, but cost an arm and a leg (about 50 yuan/kilogram) relate to problems such as import, foreign exchange again.And above-mentioned material all will discharge, and pollutes the environment.
It is low to the purpose of this invention is to provide a series of prices, effective, the positive PS printing plate stripping liquid for regenerating little to human body, equipment and environmental hazard.
This stripper has eliminated printing ink after for the version that falls, be no more than half a year standing time, the various PS versions of unbaked draw a design the version and last machine short run, earlier the figure lamina is soaked 5-10 second with this liquid at normal temperatures and pressures, by slight mechanical friction (manual, machine), just the figure lamina can be peeled off and remove totally again.
The basic aluminium oxide Grains layer sound construction of version is difficult for being damaged usually.But in stripping process, must note avoiding strong mechanical friction and damage the Grains layer, as long as the Grains layer is not destroyed, the version base just can be reused.
PS version after peeling off, in time water cleans, sensitization liquid is coated in oven dry again, regenerative PS plate.
Usually, peel off one and split PS domain lamina, as long as 2-5 minute, the printability of regenerative PS plate is identical with the new PS version that same technology is made.
Handle through distillation with the stripper of crossing, can continue again to use, needn't discharge.
During as film opaque, use writing brush, cotton or special-purpose colour-separation drafting pen pick a small amount of film opaque, be applied to treat modification figure line place, and friction gently, clean gently with immersion cotton balls or cloth again, can repair and remove.
The positive PS printing plate stripping liquid for regenerating is formulated as follows:

0.1VOL(Wt in above-mentioned 6 series prescriptions) the non-ionics III of % is (I+II) * 0.1%.
Above-mentioned stripper at normal temperatures and pressures can be formulated through even stirring.
The cost of above-mentioned stripper all is lower than external imported product, peels off one with this liquid and splits the PS version, expensive about 1 yuan.Make the regeneration version through painting photosensitive liquid, cost is in 5 yuan.
Stripping process is a normal temperature and pressure, as long as the well-ventilated is generally harmless.The available common PS version of manual operations is developed and is scrubbed with hairbrush.
