Description
Technical field
The present invention relates to the thermal transfer printing technical field, particularly relate to a kind of thermal transfer printing technology that is applied to metal species sheet material, section bar or decoration element.
Background technology
Hot transfer printing is a comparatively emerging typography, by importing only 10 years abroad into.Its principle be with pattern see through printer with special transfer ink watermark on the transfer printing dedicated paper, again with special-purpose transfer interpreter, HTHP ground is transferred to the commodity surface accurately with pattern, finishes the transfer print of product.The pattern levels are rich, bright in luster, ever-changing of printing, aberration is little, and repeatability is good, and the person that can reach the layout requires effect, and is fit to produce in enormous quantities; Transfer printing molded back ink lay and product surface are molten to be one, true to nature beautiful, improves the class of product greatly.
Hot transfer technique can use various transfer printing material, reaches different printing effects, and topmost have glued membrane transfer printing and a sublimation transfer.Wherein, the transfer paper of glued membrane transfer printing contains colloid, in the HTHP mode colloid pattern is imprinted on product surface again.And sublimation transfer is the technology of a new generation, adopts special distillation ink and sublimation transfer paper, and pattern is imprinted on can not produce colloid on the commodity; Sublimation transfer is mainly used in the transfer printing of clothes at present, and ink is to sublimate directly in the garment fabric, and strong degree is just the same with Buran, and color is sharp keen, is more suitable for coloury pattern.For example, notification number is CN 1977079A, patent name is implemented in hot transfer printing on the clothes for the disclosed hot transfer technique of patent documentation of " method and apparatus that is used for non-contact type direct dye-sublimation printing " adopts the mode of sublimation transfer just, disclose in the document and a kind ofly do not adopted transfer paper and only adopt the mode of once heating to carry out the technology of thermal transfer printing, the technical scheme of this technology is: form agent treatment layer in printing object; Spraying liquid sublimation dye on agent treatment layer penetrates in the agent treatment layer to allow transferred image, by the heating printing object, makes the dye sublimation that carries on the agent treatment layer penetrate in the expansion pore of texture of printing object.
Along with the development of hot transfer technique, hot transfer technique is widely used in fields such as antitheft door, steel door and aluminium alloy extrusions.What the hot transfer technique in this field adopted at present is the glued membrane printing---be the transfer paper printing, its main technique step is: after the surface of the work pre-treatment, by the spraying thermosetting powder coating, be heating and curing again; The modes such as stickup or vacuum suction of then transfer paper being passed through heat once more attached to surface of the work; Because thermosetting powder coating mainly is a polyester, the polyester direct by heating sublimation and in the powdery paints of the printing ink on the transfer paper combines, thereby the decorative pattern on the transfer paper, color are transferred on the workpiece.
In sum, the technological process to existing caloric transfer printing technology can reduce: surface of the work processing → spraying thermosetting powder coating → workpiece transfer paper → workpiece that is heating and curing → adheres to heats → takes off paper.
This traditional hot transfer printing technique has following shortcoming:
One, production cost height: owing to present stage thermal transfer printing arts demand intermediate transfer medium---transfer paper; And transfer paper mainly contains import and homemade difference, and homemade transfer paper quality is relatively poor relatively, and the colloid pattern that it prints off is thicker and shortcoming glutinous, that split often arranged; And the ink quality of import transfer paper and use thereof is better, and it is extremely thin to print off the colloid pattern that comes, and breathes freely, does not stick, do not split, washablely do not come off; So the more homemade transfer paper of import transfer paper costs an arm and a leg; No matter import transfer paper still is homemade transfer paper, all is that existing hot transfer technique is indispensable, can roll up production cost undoubtedly.
Two, the wasting of resources: when thermal transfer printing, transfer paper generally is adhered to surface of the work by glue, takes off paper after transfer printing finishes and handles cumbersomely, and needs to consume a large amount of water, causes the serious wasting of resources.
Three, energy waste: existing thermal transfer printing arts demand carries out twice heating to workpiece, causes energy waste.
Four, waste of manpower:, certainly will increase cost of labor because the traditional hot transfer printing technique needs a large amount of uses manually to handle at the transfer paper paster with taking off in the paper process.
Five, the easy weather stain of printing-ink: since transfer ink be direct transfer printing at surface of the work, also need carry out polishing grinding after the workpiece transfer printing is finished and handle, can cause the wearing and tearing of surface ink undoubtedly; Simultaneously printing ink directly is exposed in the natural environment, and the influence of natural conditions such as exposed to the sun and rain easily causes the weather stain of expedite product; Therefore, usually also need be armor coated after transfer printing is finished at surface of the work, can increase production cost equally like this.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of technology simple, the labour-saving thermal transfer printing technology of saving money.
Purpose of the present invention is achieved through the following technical solutions: a kind of thermal transfer printing technology, described technological process is: surface of the work processing → surface of the work printing → spraying thermosetting powder coating → workpiece is heating and curing.
Described technological process concrete steps are as follows:
At first, surface of the work is handled: the surface treatment method according to routine carries out pre-treatment to workpiece;
Secondly, surface of the work ink printing: adopt the mode of printing of conventional heat sublimation printing ink that heat sublimation printing ink directly is printed on surface of the work, the heat sublimation printing ink that is attached on the surface of the work constitutes in order to carry out the transfer ink layer of hot transfer printing;
Once more, spraying thermosetting powder coating: after ink printing finishes thermosetting powder coating is sprayed on the heat sublimation ink lay of surface of the work, to constitute the cured layer that coats heat of solidification sublimation inks layer and workpiece;
