Abstract
The utility model relates to a corona sheet used for printing or glue spreading, which belongs to the field of plastic film printing materials. The corona sheet comprises a PVC (polyvinyl chloride) or PET (Polyethylene Terephthalate) sheet, wherein the surface of the PVC or PET sheet is subjected to corona treatment, and double sides of the PVC or PET sheet are both subjected to corona treatment. The PVC or PET sheet subjected to corona treatment is characterized in that the surface roughness is increased, the dyne value is increased, and the adsorption power of the surface is increased accordingly; and if printing is performed on the treated surface of the corona sheet, printing ink can be firmly adsorbed on the sheet surface, so that the quality of printing on the PVC or PET sheet surface is greatly improved.
Description
Technical field
The utility model relates to the plastic film printing material, particularly a kind of corona sheet material that is used to print.
Background technology
In furniture, electrical equipment, packing and ornament materials, often need be at plastic sheeting surface printing literal, pattern.And the capillary size of plastic sheeting has very big influence to the quality of printing quality.Surface tension is generally used the dyne value representation, and the dyne value is high more, and surface energy is many more, so the surface is also with regard to acceptant more printing ink.The quality of ink adhesion is good more when film surface prints.For guaranteeing to obtain good printing quality or sticking strength on the plastic sheeting surface; Require the surface energy of film should be higher than more than 10 dyne values of surface energy of printing ink or adhesive; And undressed plastic sheeting surface dyne value generally is lower than the dyne value of printing ink or adhesive, and the difficult quality of printing keeps lastingly like this.
The utility model content
The utility model provides a kind of corona sheet material that plastic film printing is pasted that is used for to the requirement of prior art to the plastic film printing sticking Quality, is intended to improve the adhesive force of sheet surface, printing quality is kept lastingly, difficult drop-off.
The purpose of the utility model is achieved in that a kind of corona sheet material, comprises PVC or PET sheet material, and said PVC or PET sheet surface are through corona treatment.Corona treatment is in PVC that is processed or the discharge of PET sheet surface with the high-frequency high voltage; And the generation low temperature plasma; Make plastic sheet surface produce radical reaction and make polymer that crosslinked, surperficial roughening take place and increase its wetability polar solvent, these gas ions electric shocks and penetrating into by its molecular structure of surface breakdown of seal body, and then with the surface molecular oxidation and the polarization that are processed; The ion erosion sheet surface; It is rough and uneven in surface that the small groove of sheet surface generation is adorned, and increases the roughness of sheet surface, thereby increase the adhesive force of sheet surface.Therefore; Through the PVC or the PET sheet material of corona treatment, it is big that surface roughness becomes, and it is big that capillary dyne value becomes; Thereby the adhesive force on surface becomes big thereupon; The corona sheet surface printing of managing herein, printing ink can firmly be adsorbed on sheet surface, has improved the quality in PVC or the printing of PET sheet surface greatly.
For further increasing the adhesive force of sheet surface, be convenient to the two-sided utilization of sheet material, said PVC or PET sheet material are two-sided all through corona treatment.
As the improvement again of the utility model, said PVC or PET sheet material capillary energy after corona treatment reach 38 dyne.
Description of drawings
Fig. 1 observes sectional schematic diagram for the corona sheet material of the utility model under high magnified glass.
The specific embodiment
As shown in the figure, be the corona sheet material of the utility model, comprise PVC or PET sheet material, PVC or PET sheet surface are through corona treatment; And PVC or PET sheet material are two-sided all through corona treatment; The capillary energy of sheet material reaches 38 dyne after the corona treatment.
Among the embodiment, adopt the 5000-15000V high-frequency alternating current to be pressed in and be processed sheet surface discharge, sparking electrode spacing 1.5～2.5mm, discharge current 7～8A.After corona treatment, PVC or PET sheet surface produce the rough and uneven in surface of small channel form, and it is big that surface roughness becomes, and the surface can raise.Surface with sheet material behind the dyne pen test corona can the dyne value all reach 38 dyne.
The utility model is not limited to the foregoing description; For example, can also adopt other plastic sheet in the example, like PP etc.; Every on the basis of the disclosed technical scheme of the utility model; Those skilled in the art does not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein according to disclosed technology contents, and these replacements and distortion are all in the scope of the utility model protection.
Claims (3)
