Accompanying drawing explanation
The schematic flow sheet of the Anti-forging soft packing flexo technique that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
Core of the present invention is to provide a kind of Anti-forging soft packing flexo technique, adds the pollution of man-hour to environment to reduce flexible package.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with drawings and embodiments, the present invention is described in further detail.
Please refer to Fig. 1, in a kind of detailed description of the invention, Anti-forging soft packing flexo technique provided by the invention, comprises step: made roller by laser engraving machine.Wherein, the making of roller comprise print before to pattern process; To the process of RIP image raster; By laser engraving machine processing of printing roller; Carry out digital image-forming; Imaging is exposed and main exposure; Version is washed to image; Baking version is carried out to roller; Carry out post-exposure and go sticky after complete plate-making.
Carry out the work of subsides version.
Anilox roll and roller are installed.Concrete, the roller line number ratio of anilox roll is for 1:3. is in order to improve the printing accuracy of false proof readability and fine pattern, and preferably, the roller line number of anilox roll is than being 1:4.
Carry out the preparation of printing element; Concrete, printing element can be traditional biaxially oriented film, and in order to improve the scope of application of printing element, preferably, printing element is ventilated membrane, shrinkable film, non-woven fabrics, tissue paper or laminated film etc.
Prepare ink, ink comprises polyurethane and polyamide.Relative to the ink of traditional polyamide and nitrocotton co-mixing system, the ink of the polyurethane that the application provides and polyamide blended system, have good printing ink transfer performance, and ink limit peak can up to 18%.Concrete, in order to meet the requirement of flexographic plate anti-counterfeiting design, MOLECULE DESIGN can be carried out to distributes ink agent, super branched molecule structure provides good absorption property, strengthen organic adsorption capacity with inorganic pigment with amino respectively with the molecular end of carboxylic acid group, the macromolecular skeleton structure of particular design provides good matrix resin compatibility.
Carry out ink circulates operation.
Carry out toning work.
Carry out slaking operation.
Flexible package processing is carried out by solvent-free materials compound.Concrete, solvent-free can have the adhesive such as LA7723 and LA6031, LA7735 and LA6088, Gao Meng company YH753A and YH753B for Henkel Corp.'s solvent-free materials composite glue.Traditional, solvent-free component adhesive is generally the performed polymer of NCO end-blocking, by completing solidification process with the reaction of moisture that exists in air.Because One-component adhesive molecular weight is low, heat resistance poor (< 100 DEG C), this type of adhesive is mainly used in the compound of paper material.Solvent-free two-component polyurethane adhesive sticks agent and have employed aliphatic polyol, and such two-component polyurethane adhesive reacts to each other after sticking the two component Homogeneous phase mixing of agent dependence and forms large molecule and reach crosslinking curing.Relative monocomponent adhesive, its temperature tolerance is significantly improved, but still can not meet the demands in peeling resistance.
In order to improve the peeling resistance of solventless polymer, introduce rigid structure in the molecular structure, as aromatic ring.Can also by improving the degree of crystallinity of polymer or increasing the crosslink density of polymer.Wherein that namely solvent-free material is aromatic polyol polyurethane adhesive with aromatic polyol some or all of alternative fats race polyalcohol to prepare bi-component polyurethane adhesive the most easily.
Slaking operation is carried out to the flexible package carried out after solvent-free materials compound.Preferably, the curing time is 23 hours-25 hours, curing temperature 43 DEG C-53 DEG C, and preferred curing temperature is 48 DEG C.Preferably, the curing time is 24 hours, and maturing process time deviation≤5 minute, curing chamber environment upper, middle and lower uniformity of temperature profile, and deviation≤5 DEG C.Controlled by above-mentioned science, solve in the rolling of solvent-free materials compound package material, maturing process and often there will be the problems such as tunnel(l)ing, heat resistance is poor, combined strength bination is low.
Carry out print film checked operation.
When print film after the assay was approved, carry out start produce.
Known by foregoing description, in the Anti-forging soft packing flexo technique that the specific embodiment of the invention provides, by use laser engraving machine carry out in lithography process pollution-free, and adopt solvent-free materials compound to carry out flexible package processing, effectively reduce organic solvent volatilization pollution on the environment, therefore, Anti-forging soft packing flexo technique provided by the invention effectively can reduce flexible package and adds the pollution of man-hour to environment.
On the basis of above-mentioned each scheme, preferably, before the described anilox roll of installation and described roller, metering roll and transferring roller for controlling spread is installed, wherein, the quantity of metering roll and transferring roller is determined according to spread and actual demand, and the application is not specifically limited.In production process equipment, introducing metering roll and transferring roller, by controlling the movement velocity of metering roll and transferring roller, achieving spread controllable precise, solve in general dry adhered technique the problem needing change roller footpath and line number could change spread.Technical process simplifies greatly.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
