Description
Technical field
The present invention relates to a kind of process of surface treatment for paper wrapper, particularly a kind of printing surface to the packaging material that complete color and pattern printing process carries out surface treatment to realize the surperficial calendering method of high bright luster effect; The present invention also relates to the special equipment of realizing above-mentioned surperficial calendering method in addition.
Background technology
Traditional paper wrapper (as paper package box), adopt glazing to process to improve the surface property of printed matter, glazing processing is widely used in packing and decorating, picture album, first mate and decorates in the Surface Machining of the printed matters such as pictorial poster.In the glazing process, after the printing surface coating glazing paint of printed matter, only depend on coating nature levelling, drying can not reach desirable gloss, often there will be coating irregular, bubble is arranged, pit, streak and the phenomenon such as wrinkling, more can not reach the glazing processing request of exquisite printed matter, in order to obtain the technological effect of high bright luster, printing of the prior art generally adopts the mode of calender press polish, first the printed matter surface at the high bright luster of needs is coated with one deck oiliness calendering oil, the metal steel band through polishing with electric-heating-wire-heating again, at 100-200kgf/cm
2pressure under, impression has been coated with the printed matter surface of gloss oil, form the high finish surface coating of one deck densification after cooling at printed matter surface, form the mirror-reflection effect and obtain high gloss, but can produce in process of production a large amount of VOC (VOC) material and heavy metal substance, environmental pollution is very big.
Development along with green printing, requirement to environmental protection is more and more higher, aqueous calendering oil has also appearred on market, but owing to still adopting by the mode of heating of metal steel band high temperature press polish, speed of production is slow and very big to energy resource consumption, VOC (VOC) discharge is still arranged when producing to environment; And because calendering temperature is high, cause Paper Moisture sharply to reduce when press polish, and produce paper distortion and shrink, be unfavorable for the production of the later process such as gold stamping, cross cutting, paste box, product rejection rate is high, production efficiency is low; The packing box that simultaneously adopts calendaring technology to produce, carton surface crocking resistance is poor, and market value is low.
A kind of printing process of mirror press-finishing is disclosed in the Chinese patent that the patent No. is ZL02115313.2, in conjunction with as shown in Figure 1, this printing process comprises the following steps: the packaging material 30 that order has applied glazing paint roll by each pressure roller of mirror press-finishing equipment 10, accept external energy simultaneously the glazing paint applied on described packaging material is solidified; In above-mentioned steps, the package material surface coating is UV (ultraviolet light polymerization) gloss oil, and the annular press polish strip 13 on mirror press-finishing equipment used adopts a kind of flexible and transparent light film.In addition, also comprise step: the packaging material that will be coated with the UV gloss oil are sent between two pressure rollers 11,12 fits with described flexible and transparent light film close, and accept UV-irradiation, until after the UV gloss oil on packaging material solidifies, packaging material and described flexible and transparent light film are peeled off and are obtained the packaging material with mirror press-finishing effect.Although this technology has proposed to utilize coating UV type gloss oil the transparent membrane of fitting on printing surface, then recycle the UV light irradiation and solidify this UV type gloss oil, form mirror effect after peeling off flexible and transparent light film on printing surface; But in this piece of patent, in the press polish printing process, what transparent membrane adopted is a kind of ring-type flexible and transparent light film, this kind of flexible and transparent light film will certainly produce seam or the stack of light film at the two ends of light film to junction, and after the light film compacting that contains the stack of seam or light film solidifies on printing surface, this printed matter has flaw certainly, if large batch of production will certainly increase its product rejection rate.In addition, in this piece of patent, flexible and transparent light film is not had to too much elaboration, and there is the bright luster effect owing to forming on printing surface, be not that any flexible and transparent light film can be realized, and in this piece of patent because the parameter that does not elaborate flexible and transparent light film will cause can't realizing producing the packaging material with bright luster effect according to disclosed technical scheme in this patent.
