Description
Technical field
The invention belongs to screen print materials technical field, be specifically related to a kind of removal screen printing half tone diazo photosensitive emulsion remover and using method thereof.
Background technology
At present, for web material mainly terylene silk net and the nylon mesh of screen plate making.Because terylene silk net has the features such as good stability of the dimension, tensile strength is high, resistance is good, in the silk screen printing of usual production, rate of utilization accounts for more than 90%.The plate-making material of screen mesh printing plate is based on compound diazo resin photoresists half tone, and diazo photosensitive emulsion sold on the market is normally based on the emulsification of the crosslinked polymer such as polyvinyl alcohol, polyvinyl acetate (PVA).Screen template is the character and graphic making printing on the half tone netted of stretching tight with photoresists.As the basis of silk screen printing, thus the quality of template quality will be directly connected to the quality of wire mark quality.After making half tone failure or wire mark task complete, for making silk screen recycle, often need carry out the operation of half tone demoulding.For the half tone that short run is lived, if repeatedly an edition membrane removal can be carried out, can silk screen be saved undoubtedly, reduce the operation such as net, wire side roughening treatment that stretches tight, reduce costs and consume with work, increase economic efficiency.
The problem often run in recovery membrane removal has two kinds.One is, after membrane removal process, screen cloth leaves remaining film; Two be owing to printing print used material, and if ink, slurry etc. are in printing process, be deposited on screen cloth produce ghost with screen cloth effect, and the color of print material or slurry is darker, " ghost " is more obvious.Sometimes screen mesh printing plate has de-unclear word, image, also cannot slough with liquid parting, this also leaves over caused by fine ink and spot in screen mesh.Usually can wipe by direct solvent, as pimelinketone, pore-creating agent etc., word on silk-screen plate, image will be disappeared by dissolution with solvents at leisure, but silk-screen plate still can not be known as newly, now constantly dab in scraper plate face and printing surface with scrubbing powder or toothpaste, a little input a little pimelinketone, solvent based while be close to, until word, image all disappear on silk-screen plate again.Then rinse well with water blast gun, finally with Glacial acetic acid neutralization, cleaning, dries.
Up to the present, the research carried out wire printing material photosensitive offset film remover is both at home and abroad reported few.The test of CN1407033 finds, the liquid parting utilizing oxygenant and organic solvent etc. composite effectively can slough photoresists, but contain a large amount of organic solvent in its composition as alicyclic hydrocarbon ketone, phenols, aliphatics list (many) alkyl, polyhalohydrocarbon and pyrrolidinone compounds etc., in use exist volatile, potential hazard is caused to HUMAN HEALTH, formula is solution state, cause transport inconvenience undoubtedly and increase production cost, reducing the economic benefit of enterprise.
