Abstract
The present invention belongs to the technical field of counterfeiting prevention, and particularly relates to a manufacturing method of heavy ion micropore anti-fault membranes, which comprises the following steps: precoating anticorrosive hot-melt adhesives on the single side of an anticorrosive plastic membrane to form a precoating membrane; irradiating the plastic membrane by heavy ions to form an irradiation membrane; combining the precoating membrane with the irradiation membrane by heating to form a composite membrane; printing patterns on the surface of the irradiation membrane by printable hot-melt adhesives; processing the hole diameter of the micropores of the heavy ions into 3 to 5 mu m by chemical etching; removing the precoating membrane combined on the irradiation membrane after etching; washing and drying the irradiation membrane to obtain a heavy ion micropore anti-fault membranes whose pattern areas are milk white in color and non-pattern areas keep the original transparency of the plastic membrane. The present invention uses the technologies of double-side protection and single-side printing, has low requirements for the accuracy of apparatuses, and easily manufactures the membranes in technology. With the double-side protection, the imaged patterns are clear and have good quality; the precoating membranes are easy for mass production, and the present invention has the advantages of mature technology and low cost.
Description
Technical field
The invention belongs to field of anti-counterfeit technology, particularly use the manufacture method of the integrated technology manufacturing heavy ion micropore anti false film of nuclear technology, chemical industry technology, printing technology.
Background technology
In recent years, heavy ion micropore anti-counterfeiting technology had been brought into play the vital role that can't copy with its superior anti-counterfeiting performance on commodity false proof, show up prominently in false proof industry.But, restricted the raising of reduction, outward appearance and the output of cost because complex technical process is not mature enough.
Application number be 93106945.9 and application number be 94104555.2 patent of invention, its manufacture method is the template of placing a pattern hollow out between irradiation bomb and organic film, heavy ion carries out irradiation by the zone of hollow out to organic film, carry out etching with chemical liquid then, form pattern, its pattern is to carry out selectable irradiation by openworking template to form.Because be subjected to the restriction of hollow out, the pattern of making is not meticulous, irradiation imaging device complexity, thereby yield rate is low.
Application number is that 97120352.0 its manufacture methods are with method of printing polypropylene, the anti-etching material of polyesters to be printed on through on the film of irradiation, and non-pattern area is protected, and etches the pattern without protection then, finishes imaging.This patent disclosure be a kind of the film single face to be carried out the technology of printed patterns, and the another side of film does not process, and it is not effectively protected, and easily causes non-pattern area unclarity, outward appearance is bad, and influences the effect that the consumer tints and differentiates.
Application number is that 98102546.3 patent is the weak point that overcomes said method, adopts on the tow sides same position and prints, and this kind technological requirement printing equipment precision is very high, and the difficulty of enforcement is very big, goes out waste product easily, therefore causes yield rate low, the cost height; Because the two-face printing pattern can not definitely align, so pattern edge is fuzzy, unintelligible, influences attractive in appearance.
Summary of the invention
The objective of the invention is to design a kind of manufacture method of heavy ion micropore anti false film, adopt two-sided protection, technology is printed on one side for overcoming the weak point of prior art; owing to only need be printed on one side; do not need the version printed on both sides, therefore low to equipment precision requirement, realize easily on the technology; because two-sided protection; the clear patterns of imaging, quality is good, and pre-coating film is easy to produce in enormous quantities; technical maturity, cost is low.
The present invention proposes a kind of manufacture method that adopts heavy ion micropore anti false film, may further comprise the steps:
1) on the plastic sheeting of etch resistant, the good anti-etching hot-melt adhesive of one-sided precoat becomes pre-coating film;
2) plastic sheeting is become irradiated membrane through heavy ion irradiation;
3) heating of said pre-coating film and irradiated membrane is combined with each other becomes composite membrane;
4) use printable anti-etching hot-melt adhesive printed patterns on the surface of said irradiated membrane;
5) use chemical etching then, making the heavy ion micropore size is 3~5 μ m, throws off at the pre-coating film that will be compounded on the irradiated membrane after the etching, and promptly getting pattern area after the flushing oven dry is milky, and non-pattern area keeps the heavy ion micropore anti false film of the original transparency of plastic sheeting.
The present invention proposes the another kind of manufacture method that adopts heavy ion micropore anti false film, may further comprise the steps:
1) on the plastic sheeting of etch resistant, the good anti-etching hot-melt adhesive of one-sided precoat becomes pre-coating film;
2) plastic sheeting is become irradiated membrane through heavy ion irradiation;
3) use printable anti-etching hot-melt adhesive printed patterns on a surface of said irradiated membrane;
4) another surface heating of said pre-coating film and irradiated membrane is combined with each other becomes composite membrane;
5) then to the composite membrane chemical etching, making the heavy ion micropore size is 3~5 μ m, throw off at the pre-coating film that will be compounded on the irradiated membrane after the etching, promptly getting pattern area after the flushing oven dry is milky, and non-pattern area keeps the heavy ion micropore anti false film of the original transparency of plastic sheeting.
The said anti-etching hot-melt adhesive of the present invention can be with conventional anti-highly basic, the hot-melt adhesive of anti-50 ~ 100 ℃ of temperature, as the resene hot-melt adhesive.
It is among the transparent polypropylene, tygon, polyester, polycarbonate plastic film of 15~40 μ m any one that the plastic sheeting of the said pre-coating film of the present invention can adopt thickness.
It is among the polypropylene, polyester, polycarbonate transparent plastic sheeting of 10~35 μ m any one that the plastic sheeting of the said irradiated membrane of the present invention can adopt thickness.
Specific implementation method in each step of the present invention is the common process of present technique field maturation.
Characteristics of the present invention:
The present invention adopts and is printed on one side; another side " pre-coating film " protection; when chemical etching; owing to only there is the pattern area of one side not to be protected; therefore the ionization damage that forms through irradiation on this a part of film is etched into and is tapered micro holes; the naked eyes macroscopic view is seen white; other zones are because the two sides all has anti-etching dose to be protected; therefore be not subjected to any etching; and the original pellucidity of maintenance film; throw off at the pre-coating film that will be compounded on the irradiated membrane after the etching, on film, just obtained pattern area like this and be white, the good heavy ion micropore of non-pattern area transparency anti false film.This technology does not need the version printed on both sides owing to only need be printed on one side, and is therefore low to equipment precision requirement, realize easily on the technology, and the clear patterns of imaging, quality is good, and pre-coating film is easy to produce in enormous quantities, technical maturity, cost is low.
Print on this film simultaneously anti-etching dose, it is again a kind of hot-melt adhesive, thus can with this pattern film directly heating be compounded in and make needed anti-counterfeiting mark on the backing material.Save the operation of the multiple needed coating adhesive of film of secondary.And this technology makes pattern area not have bonding agent, makes the micropore of forming pattern can be not blocked behind multiple film, has guaranteed the permeability of micropore.Make that anti-counterfeiting mark colouring, permeable, print through performance are better guaranteed.
