The product that the method for laser electrochemical aluminum stamping systems on metal coins of the present invention is made, it is laser electrochemical aluminum stamping systems 8, basement membrane film strips 1 is provided with five-layer structure, be followed successively by from inside to outside by basement membrane one side surface: release layer 2, imaging layer 3, embossed plies 4, aluminium coated 5, adhesive layer 6, wherein said adhesive layer 6 is two adhesive layer structures; Further illustrate adhesive layer 6 described in laser electrochemical aluminum stamping systems of the present invention for two adhesive layer structure, be two adhesive layer structures of different layers structure, different adhesive layer structure is respectively elasticity gluing toughening layer 6-1 and gluing adhesive force enhancement Layer 6-2; Also consider while making pattern decoration have wear-resisting, weatherable layer to ensure its trimming performance except there is excellent adhesive force.
The present invention is when laser electrochemical aluminum stamping systems completes gold stamping rear separation, and separation point position is that described release layer 2 is separated with described imaging layer 3, and described release layer 2 tears off thermoprint thing metal coins together with described basement membrane film strips 1.
Mold pressing has the described basement membrane film strips 1 of holographic pattern to carry out the described aluminium coated 5 of vacuum aluminum-coated formation by vacuum aluminum-plating machine by the present invention, described aluminum layer thickness is 2.0 Ω with resistance measurement, aluminum layer thickness is measured because the aluminium coated on vacuum aluminized film is very thin, therefore its thickness can not be detected with the thickness measuring instrument of routine, conventional detection method is electric-resistivity method, utilize the thickness of Ohm's law to aluminium coated to measure, according to Ohm's law R=ρ × L/S, the resistance value of unit are metallized film is less, the thickness of its aluminium coated is thicker, otherwise it is then thinner, the thickness that electric-resistivity method detects aluminium coated represents by sheet resistance, unit is Ω, numerical value larger explanation aluminum layer thickness is thinner, standard GB/T/T 15717-1995 " vacuum metal thickness of coating test methods electrical resistance method " has carried out detailed regulation to this method.
The described release layer 2 of prior art is usually adopt water wax or OP wax, metal coins surface after release layer is separated can not be printed again, because the dyne value of water wax is low, water wax is separated with basement membrane film strips 1, water wax is retained on imaging layer 3, the surface printing-ink again that can not realize after metal coins thermoprint holographic pattern owing to there being wax to exist, the present invention adopts melmac or celluosic resin as mould release, its key is melmac or celluosic resin is along with basement membrane film strips 1 departs from embossed plies 4, not residual attachment on imaging layer 3, so printing-ink again can be completed, the object of printing after realizing holographic pattern thermoprint.
What described imaging layer resin of the present invention adopted is high temperature resistant, wear-resisting resin, makes pattern decoration have wear-resisting, weatherability, has protective effect.
The present invention is in the process of coating adhesive layer, prior art is at papery or cloth surface by electrochemical aluminum foil thermoprint, sticky glutinous object is soft material relative to metal coins, the thickness of usual coating adhesive is thicker, it is generally acknowledged that gluing is The more the better, what adhere to is more firm, metal coins is coated with adhesive on the contrary, because metal coins is the smooth surface cast out, the adhesive of coating is slightly more, adhesive layer slightly thicker due to glue be that the soft fearness that just produces is scraped, softening, caducous problem, by experiment analyze the present inventor think on paper material, apply adhesive after paper material there is certain permeability, adhesive has sticky stickiness more and strengthens, sticky glutinous firmly situation, and metal coins smooth surface, and there is no permeability, the slightly more stickiness of will gluing of coating adhesive declines, easy scratch, though can not cohere on metal coins surface securely, therefore, the adhesive being coated on metal coins surface is get over Bao Yuehao relative to the adhesive coating layer thickness being coated on papery thermoprint thing surface, described like this adhesive is strengthened greatly at the firmness of metal coins surface attachment, select suitablely have the resin of good compatibility to be also very important with metal.Be coated with adhesive with coating machine, coating thickness is expressed as by its coating dry measure: 0.7-0.9 g/m2, and such trimming, dry at 140 DEG C of-160 DEG C of drying chambers through bake out temperature, the firmness of adhesive adhesiving metal thing meets design requirement.
In addition for the adaptability problem of ink printing after release layer 2 and thermoprint, celluosic resin is then the situation being applicable to the thinner ink layer of printing as release layer for the printing-ink of metal coins, and melmac is more suitable for the printing of ink layer compared with heat-bodied oil ink as release layer for metal coins ink printing.
