Description
Technical field
The utility model relates to a kind of holographic false proof printing industry material, particularly a kind of regeneration laser electrochemical aluminum film.
Background technology
In the anti-counterfeit package industry, for improving the antifalse effect of product, the application of holographic laser laser anti-counterfeiting electrification aluminium more and more widely; Its consumption also so year by year increases substantially, but in laser electrochemical aluminum film preparation process, is basement membrane mostly with the polyester film; Evenly be coated with the coating that one deck or multilayer have different chemical character coating above that, adopt hot moulding operation and blanching seal operation to accomplish whole process of preparation again, in the production process of hot moulding; Usually can run into the phenomenon of sticking version peeling; The industry generally believes that the reason that this phenomenon causes is that molding temperature is too high, and the viscosity of coating is excessive to be caused, and the solution that generally adopts is to reduce molding temperature; Reduce molding temperature and can not satisfy the requirement of the brightness of product again molding temperature; Influence product appearance effect and quality, if molding temperature is too low, the brightness of then electrochemical aluminium film is not enough; If molding temperature is too high, then cause the problem of the sticking version of mold pressing peeling easily, cause product to roll off the production line.Therefore each is engaged in the enterprise that electrochemical aluminum is equipped with; All there are the coating that the is difficult to mold pressing in a large number semi-finished product that roll off the production line, cause decrease in yield, caused waste; This cause large quantities of filmed at product material because the sticking version phenomenon of mold pressing procedure and compelled situation about rolling off the production line were merely able to abandon such at goods in the past; Cause very big waste to company, how will be about to become condemned MAT'L and utilizing again again with the coated film material of abandoning becomes engineers and technicians' problem anxious to be solved, hope can be found a kind of method or material to make to roll off the production line to be reused again at goods; Solve simultaneously and guarantee molding temperature when promptly keeping coating brightness, mold pressing; Also in mold process, overcome and occur peeling haftplatte phenomenon easily, convenient control, reducing the mold pressing percent defective is the problem that engineers and technicians press for solution.
Summary of the invention
The purpose of the utility model is exactly in order to overcome defective that above-mentioned prior art exists, to provide a kind of and can overcome at product defect, through the secondary coating regeneration laser electrochemical aluminum film that semi-finished product process that rolls off the production line.
The purpose of the utility model is to accomplish through following technical scheme:
A kind of regeneration laser electrochemical aluminum film of the utility model; Comprise: on basement membrane, be coated with release layer, imaging layer, aluminium coated, glue-line successively as substrate layer; Wherein: between imaging layer and aluminium coated, be provided with the interval regeneration zone for 200-225 ℃ of one deck heatproof, the amount of regeneration zone coating composition is controlled at 0.05-0.6g/m
2Between, regeneration zone thickness is 0.025 μ m-0.3 μ m, said regeneration zone is the acrylic resin coating that contains filler nanometer silica.
The method of the described regeneration laser electrochemical aluminum of the utility model film, wherein: the said interval regeneration zone for 200-225 ℃ of one deck heatproof that between imaging layer 3 and aluminium coated 5, is provided with, the amount of regeneration zone coating composition is controlled at 0.1-0.4g/m
2Between, regeneration zone thickness is 0.06 μ m-0.2 μ m, said regeneration zone is the acrylic resin coating that contains filler nanometer silica.
The utlity model has following remarkable advantage: provide a kind of and can overcome, can reach the next procedure technological requirement through the secondary coating regeneration laser electrochemical aluminum film that semi-finished product process that rolls off the production line in the goods sticking version of peeling phenomenon during in mold pressing; Make and become being utilized again of waste product at goods; Use simultaneously after the regeneration laser electrochemical aluminum film; Mold pressing speed can be brought up to 45m/min by original 30m/min, and production efficiency has improved 50%, and the coating of the said preparation of the utility model regeneration laser electrochemical aluminum film is a kind ofly can effectively improve the regenerated coated coating of the durothermic mold pressing of electrochemical aluminium semi-finished product mold pressing; Adopt the regeneration laser electrochemical aluminum film of this applying coating to be difficult for the peeling haftplatte; Easy operating improves the yield rate that electrochemical aluminum is equipped with, and promptly through the performance of improving coating sticking version and the skin effect phenomenon that Yin Wendu control problem causes is resolved; The surface brightness of the film band of mold pressing is higher, apparent excellence; Actual fabrication from the utility model product; The utility model coating can obviously improve the practical problem that in preparation, runs into, and can significantly improve yield rate, improves preparation efficiency; Making rolls off the production line is reused at goods again; Obtained gratifying effect at the economical with materials and the energy and aspect such as reduce cost, the stability that the utility model coating can guarantee to prepare and the serviceability of product, and can bring bigger economic benefit for company.
