Summary of the invention
One of purpose of the present invention is to provide the method that imprints the rough surface (china biscuit surface) of object after a kind of design (subscript) inking that will be formed at forme by the bat printing circle pad that is fit to, the special character of this technology is that it can be at forme creation single-image layout (subscript), it is impressed can not deform behind the ceramic surface, solves the defective that prior art exists.
For achieving the above object, the present invention adopts following technical scheme:
1, a kind of method for transfer printing of underglaze logo of bone porcelain comprises the steps:
1.1) make one and go to the bottom with glaze to be transferred and to mark the identical supporting body of china object biscuit shape;
1.2) form the glaze to be transferred that deformation can the not occur target pattern of going to the bottom at supporting body;
1.3) to the glaze to be transferred target pattern fills transfer ink of going to the bottom;
1.4) shift inking pattern on the supporting body with the transfer printing packing ring, the inking pattern is impressed into glaze to be transferred goes to the bottom on the mark china object biscuit;
1.5) fully behind the china object biscuit of dry transfer printing inking pattern to be decorated, the spraying bone china glaze, 1080 degree Celsius were fired 2-8 hour to 1160 degree are lower, naturally cooled off, and formed the china glaze to be transferred mark of going to the bottom.
Preferred scheme is: described supporting body is the metal supporting body, and described transfer printing packing ring is the silicone gasket of domed shape or arched roof shape.
More preferred scheme is: the pattern that described step 1.2) forms on the supporting body is that engraving or engraving method are made.
Two of purpose of the present invention is to provide a kind of transfer printing china glaze target transfer printing ink system of going to the bottom, and solves the defective that prior art exists.
For achieving the above object, the present invention adopts following technical scheme:
A kind of for the described transfer printing ink system of the arbitrary scheme of one of goal of the invention, comprising:
(a) inorganic component pigment or the colorant of at least a stable storage;
(b) weight ratio is 10% to 25% printing varnish, described printing varnish is that clear solution or gel are dissolved in the polymerization organic bond system that organic solvent forms, and this organic solvent comprises that 70w% is to trimethylbenzene or the trimethylbenzene derivative of at least a boiling spread between 150 degree Celsius are spent to Celsius 250 of 100w%; 0 to 50w% at least a essential oil as the dissolving plasticizer, 0 to 30w% at least a solvent that contains alcohols, ethers or ester class group;
(c) be no more than 10w% glass solvent;
(d) be no more than the conventional adjuvants of 10w%;
Wherein, the component of solid is more than the whole transfer printing ink system 70w%.
Preferred scheme is: described adhesive system also comprises the similar or/and copolymer of at least one or a plurality of (C3-C2)-acrylate; Described organic solvent comprise 70w% at least a boiling spread of 100w% at 150 degree Celsius are above between spending to Celsius 250 trimethylbenzene derivative, the Venice turpentine of 0 to 30w% conduct circle pad adhesive, and 0 to the 30w% at least a solvent that contains alcohols, ethers or ester class group.
Three of purpose of the present invention is to provide a kind of transfer printing china glaze target equipment of going to the bottom, and solves the defective that prior art exists.
For achieving the above object, the present invention adopts following technical scheme:
A kind ofly comprise a supporting body fixture for the described equipment of the arbitrary scheme of one of goal of the invention, a china object biscuit fixture, a transfer printing packing ring bogey, and one be transferred to the transfer device of china object biscuit with the inking pattern from supporting body.
Transferring system among the present invention has used the depression metallic plate, and metallic plate can be the chromium plating copper coin, and the chromium plating copper coin is carved with the design space of a whole page, and the opposite other end of metal plate carved region is with manually filling up mill base.The moving ink scraper, Non-design region on the cleaner plate face; In order to shift, also need to use the dome-type transfer packing ring that is consisted of by silica gel, in general, packing ring is conical; Be used for the profile of packing ring of machine and the character that diameter depends on decorated ceramic surface.Stick up stage of pigment pattern at packing ring, shift packing ring and be driven plain at the planographic plate; But in the transfer printing stage, packing washer deforms it on the china surface, covers the outline of decorated matrix.
Concrete operation step is as follows:
Move forward scraper plate, allow printing ink fill up engraving or the corrosion area of galley; In the drawback movement, scrape off the mill base of planar section on the printed panel with scraper, make mill base only stay sunk area; Reduce to shift to enclose and fill up to printed panel, stick up mill base from sunk area, when the transfer packing ring is moved toward ceramic object, scrape printing ink at printed panel, allow printing ink fill up sunk area, for next circulation is prepared; At last, packing ring is moved to ceramic object place, the downward modulation packing ring is also pressed at the irregular of object or rough surface loam cake, and gasket deforms meets external form or other irregular contour of object depression, and the design on the printed panel has just been transferred to the surface of decorated object fully like this.
Although only be directed to the china ceramic matrix about description of the invention, it also is fit to target transfer printing under other type tableware or the ceramic surface fully.
The present invention compared with prior art has the following advantages and beneficial effect:
The present invention adopts circle seal system in order to decorate or to impress at irregular surface such as convex surface, concave surface or coarse matrix surface, and circle seal system comprises the use of using and shift the circle pad of depression metal supporting body.Design or decoration at ceramic crude green body (especially china) irregular surface impression are metal supporting bodies consistent with china crude green body shape of design, and at the pattern of its surface engraving or the described transfer printing of etching; In the operation, mobile scraper makes mill base fill up carving area (effect of scraper plate is exactly to repeat to deliver mill base); The downward modulation silicone gasket sticks up the dispersible pigment color paste pattern to printed panel from carving area, then guarantees that with doctor cleaning galley surface non-decorative zones do not leave over any mill base; At last, shift packing ring contact target object, all pigment all has been transferred to the target object surface; After the transfer printing, thoroughly cleaning circle pad does not stay any remnants.
A key character of the present invention is for can accurately carrying out the first impression on this object that has irregular or a complex surface of similar pottery, decorate, burning till very large possibility is provided, and before this, these are considered to unpractical, special value of the present invention is that it can be used for making monochromatic pattern, i.e. end mark.
Shifting the circle pad is to make of soft silicon rubber, dome type structure, smooth surface; The lower clamping ring pad is to engraving or during corrosion area, the flatten layout of carrying inking of dome type circle pad; Then, press down extremely decorated object surface of soft circle pad, the circle pad is through after the more complicated distortion, and the surface can conform to the irregular surface of decorated object, is carried on like this surface that the inking pattern that encloses on the pad just has been transferred to decorative object; The viscosity pottery mill base that is specifically designed to transfer printing is transferred to the irregular surface of object by suitable transfer circle pad, after 4 to 5 of the lower bakings of 1160 degree Celsius as a child, can not deform, can produce gratifying pattern at very irregular ceramic surface.
