Description
The present invention relates to a kind of composite plate material for lithographic printing, also relate to a kind of method of making this compound plate.
On printing industry, lithography technique has obtained generally to promote at present.Along with applying of lithography technique, also growing to the demand of lithographic printing plate material.So far, employed plate is commonly all-metal stencilling material in the lithography process both at home and abroad, promptly full aluminium stencilling material.Though, advantages such as that full aluminium stencilling material has is easy to use, steady quality, press resistance rate height, image resolving rate height, flatness height and flexility are strong, but the consumption of metallic aluminium is big, and the requirement of the flatness of aluminium flake is high, thereby makes the general aluminium machine that rolls be difficult to satisfy this requirement.
In order to address the above problem, someone once attempted to make aluminium lamination and other non-metallic material bed of material to carry out compound, specific practice is to adopt binding agent that the aluminium lamination and the non-metallic material bed of material are glued together, thereby make compound lithographic printing plate material to replace full aluminium stencilling material, for example put down in writing the trial of relevant this respect among day clear 58-12792 of disclosure special permission communique.The content of putting down in writing from this patent specification, people can make aluminium lamination and nonmetal layers such as ground paper, polypropylene film and nonwoven dry goods carry out compound, and make the tearing toughness of aluminium lamination consistent with these nonmetal layers with tensile properties, but employed aluminium lamination is too thin, have only 20 microns, therefore insufficient strength causes folding line, the industrial comparison difficulty that implements easily when printing.Do not form protective layer on the surface of aluminium lamination and nonmetal layer in addition yet, thus make nonmetal layers such as aluminium lamination and ground paper result of use and all be subjected to influence service life.
The objective of the invention is to provide a kind of basic design and above-mentioned lithographic printing composite boards different, that further improved, this plate not only can reduce the consumption of metallic aluminium greatly, make the flatness of aluminium lamination itself require to reduce, and the intensity of aluminium lamination and even monoblock composite board is further improved, further improve press resistance rate, and result of use (comprising printing quality and image resolving rate) is further improved.
Purpose of the present invention also will provide a kind of method of making above-mentioned lithographic printing with composite board, thereby the plate that this method is made can satisfy above-mentioned requirements.
The present invention constitutes like this, it is a kind of lithographic compound plate that is used for, mainly form through adhesive bond by aluminium lamination and nonmetal layer, it is characterized in that said aluminium lamination and nonmetal layer have different tearing toughness and tensile properties, and the surface of aluminium lamination has surface coarsening layer and oxidation film layer, and there is the resin bed with anti-water, anti-oil and anti-corrosion property on the surface of nonmetal layer.
The present invention constitutes like this, it is a kind of method of making lithographic printing with composite board, bonding comprising aluminium lamination and nonmetal layer being carried out with binding agent, plate after bonding is flattened typing, dry then, it is characterized in that bonding preceding elder generation carries out surperficial ungrease treatment, ac electrolytic roughening surface treatment and alternating current electrolysis surface film oxide to aluminium lamination and generates processing, after bonding again at the surface applied resin bed of nonmetal layer, and after oven dry again at aluminium lamination surface applied photosensitive layer.
Lithographic printing of the present invention is compared with the compound plate of being reported on composite board and full aluminium stencilling material and the Japanese documentation and is had following advantage:
1. the aluminium amount that is exhausted only is 1/6～1/5 of full aluminium stencilling material.
2. the requirement of the flatness of aluminium lamination itself is low, and general milling train can be rolling.
3. the intensity height of aluminium lamination and even monoblock composite board, and have excellent waterproof, grease proofing and Corrosion Protection, the press resistance rate height, service life is also long.
Below, will come the present invention for a more detailed description by embodiment and accompanying drawing thereof.
Accompanying drawing is the schematic cross-section of lithographic printing of the present invention with composite board.
With reference to this accompanying drawing, composite plate material for lithographic printing of the present invention mainly is bonded through binding agent [4] by aluminium lamination [3] and nonmetal layer [5], there are surface coarsening layer and oxidation film layer [2] in the surface of aluminium lamination [3], the surface of nonmetal layer [5] has and has anti-water, the resin bed of anti-oil and anti-corrosion property [6].Here said aluminium lamination [3] has different tearing toughness and tensile properties with nonmetal layer [5], specifically, the tearing toughness of aluminium lamination be 1000～1150 the gram/square metre, the tearing toughness of nonmetal layer be 120～250 the gram/square metre.Here respectively aluminium lamination and nonmetal layer have been provided an acceptable tearing toughness scope, and do not required that both must be consistent, thereby guaranteed to have brought convenience under the industrial enforceable prerequisite selection of aluminium lamination and nonmetal layer.The thickness of aluminium lamination [3] is 30～100 microns in the compound plate of the present invention, and the thickness of nonmetal layer [5] is 200～500 microns.This compound plate is owing to mainly be the resin bed [6] that constitutes and comprise adhesive layer [4], non-metal base laminar surface by thin aluminium lamination and thicker nonmetal layer, so can reduce flatness requirement by the plasticity that resin bed produced of nonmetal layer, adhesive layer, non-metal base laminar surface to aluminium lamination itself, therefore available general milling train comes rolling this aluminium lamination, even its flatness of rolling aluminium lamination is undesirable, also can by with the compound composite plate material for lithographic printing that makes high-flatness of nonmetal layer.Here, it is suitable that the thickness of aluminium lamination [3] is 30～100 microns, too thick can increase the consumption of aluminium thereby cause product cost to rise, and also can hinder nonmetal layer etc. to give play to due plasticity effect; Approach very much the intensity that can weaken compound plate, in use caused folding line easily, thereby brought difficulty can for the enforcement of industry.What be used as nonmetal layer [5] in the compound plate of the present invention is the ground paper base, but materials such as also available nonwoven and plastic sheet replace.The thickness sum of the roughened layer on aluminium lamination surface and oxidation film layer [2] is 5～15 microns, and this very thin special top layer has been enough to satisfy the surface requirements of making the lithographic printing plate material.The resin bed of non-metal base laminar surface [6] is the melamino-formaldehyde class, and its thickness also is 5～15 microns.This resin bed has the effect of the intensity of waterproof, grease proofing, anticorrosion and the compound plate of enhancing monoblock.In addition, the binding agent that constitutes adhesive layer [4] is a binding agent for the dual liquid type urethane that polyamine fat is, also can adopt other binding agents or other serial binding agents of Polyurethane system certainly.At last, on the roughened layer of aluminium lamination and oxidation film layer, also have one deck photosensitive layer [1], so just formed complete composite plate material for lithographic printing.
