Description
Technical field
The invention belongs to the plate making technical field, particularly relate to the developer solution that the light sensitive plate to sensitization develops.
Background technology
Printing now mainly comprises developer (as NaOH, potassium hydroxide, sodium silicate) with the developer solution of PS light sensitive plate, protects and expands agent (sodium phosphate, potassium chloride), emulsifying agent (neopelex, TX-10 etc.), solvent (deionized water, distilled water).
The CTP printing technology is very fast, faster with the thermosensitive CTP speed of development especially at developed country's speed of developments such as America and Europe, Japan, CTP total installed capacity amount be the heat-sensitive plate-making machine more than 60%.Since 96 years, China CTP is in investigation always, prove, look around during profit paces up and down.There is the printing house of purchase desire and strong purchase CTP platemaking machine a lot, but is limited to the plate dependence on import, hold at high price, homemade version is called again and again again and be can't get out " afford horse, can not join saddle ", so choose which kind of CTP platemaking machine, be the dithery difficult problem of printing trader always.The development of China CTP is subjected to the restriction of plate, this situation has continued several years always, the international printing technology exhibition up to the 5th Beijing, soon releasing of the release of homemade temperature-sensitive version and homemade photosensitive silver version and photopolymer, make the user buy CTP and be equipped with confidence, printing manufacturer can be relieved audaciously according to from the situation choosing equipment, dawn has been seen in the development of the CTP of China since then.But the import developer solution of CTP temperature-sensitive version usefulness is too expensive, and domestic developer solution price reaches 250 yuans for per 20 liters at present.
Summary of the invention
The purpose of this invention is to provide a kind of developer solution of low-cost CTP temperature-sensitive version usefulness, and can also be used for the developer solution that the PS light sensitive plate develops.
Prescription of the present invention is:
A kind of developer solution of thermosensitive positive-type photosensitive plate for printing is characterized in that comprising following raw material and weight portion prescription:
NaOH 20.00～200.00 grams, anhydrous sodium metasilicate 2400.00～3000.00 grams,
EDTA disodium 60.00～100.00 grams, gluconic acid sodium salt 160.00～200.00 grams,
Tetramethyl ammonium chloride 10.00～30.00 grams, APES 100.00～140.00 grams,
Tetrafluorosilane 16.00～30.00 grams, sodium sulphite 36.00～50.00 grams,
Dodecyl phenol polyethenoxy ether 40.00～60.00 gram water 20000.00 grams,
Wherein water is deionized water or distilled water.
In the above-mentioned prescription, the effect of each raw material is as follows:
1, lytic agent: being used to dissolve on the light sensitive plate should dissolved, removed photoresists (as photoresists), as with NaOH, anhydrous sodium metasilicate, sodium carbonate etc.
2, complexing agent: be used for further removing calcium, the magnesium ion of ionized water or distilled water, use the EDTA disodium.
3, protective agent: with the not photoresists on the gluconic acid sodium salt film forming protection galley, the photoresists that should be not dissolved do not fall of protection (as photoresists not) exactly.On the light sensitive plate of handling with the developer solution that gluconic acid sodium salt is arranged, observe under 80 power microscopes, the edge of photoresists is very not level and smooth, and on the light sensitive plate of handling without the developer solution of gluconic acid sodium salt, observing not under 80 power microscopes, there is ripple at the edge of photoresists.As seen there is the developer solution of gluconic acid sodium salt can improve printing precision.
Anti-crystallization protection developer solution never degenerates, and developer solution is the low-temp storage state in the winter time, and lytic agent easily makes whole developer solution produce crystallization, can prevent crystallization with gluconic acid sodium salt.
4, emulsifying agent: the various materials in the solution are uniformly dispersed, are better than independent use with tetramethyl ammonium chloride, APES, being used of dodecyl phenol polyethenoxy ether.。
5, defoamer: owing to there is emulsifying agent to produce foam, for prevent developer solution with developing process that light sensitive plate contact in produce foam, the usefulness tetrafluorosilane is as defoamer.
6, antiseptic: prevent that developer solution from depositing, the developing process that contacts with light sensitive plate is corroded, and uses sodium sulphite.The preferred developer solution of the present invention comprises following raw material and weight portion prescription:
NaOH 40.00 grams, anhydrous sodium metasilicate 2800.00 grams,
EDTA disodium 80.00 grams, gluconic acid sodium salt 200.00 grams,
Tetramethyl ammonium chloride 20.00 grams, APES 120.00 grams,
Tetrafluorosilane 20.00 grams, sodium sulphite 40.00 grams,
Dodecyl phenol polyethenoxy ether 60.00 grams, water 20000.00 grams,
Wherein water is deionized water or distilled water.
Developer solution of a kind of thermosensitive positive-type photosensitive plate for printing of the present invention and preparation method thereof may further comprise the steps:
The 1st the step, under normal temperature condition, sequentially EDTA disodium, NaOH, anhydrous sodium metasilicate, gluconic acid sodium salt are dissolved in the water, treat to dissolve fully;
The 2nd step, adding tetramethyl ammonium chloride are treated to dissolve fully;
The 3rd step, adding APES are treated to dissolve fully;
The 4th step, adding tetrafluorosilane are treated to dissolve fully;
The 5th the step, add the dodecyl phenol polyethenoxy ether, treat to dissolve fully;
The 6th step, adding sodium sulphite are treated to dissolve fully, stir after 2 hours, and the bottling sealing is stand-by.
Advantage of the present invention: developer solution of the present invention only is about 50 yuans for per 20 liters, has reduced by 200 yuans for per 20 liters 250 yuans than domestic developer solution, and economic benefit is very obvious.
Developer solution of the present invention reaches the technical merit of domestic developer solution to the development effect of the PS light sensitive plate of sensitization and CTP temperature-sensitive light sensitive plate.So, developer solution of the present invention under the condition of ensuring the quality of products, the reduction of several times cost.
Can remove remaining calcium, magnesium ion in deionized water or the distilled water because contain the EDTA disodium in the developer solution of the present invention, so developer solution of the present invention is lower than the developer solution of existing other prescription to requirements in water quality, then calcium in the water, magnesium ion are little to developer solution quality influence of the present invention.
Because contain gluconic acid sodium salt in the developer solution of the present invention, so developer solution of the present invention can prevent crystallization, quality is more guaranteed in storage period.
