Description
Technical field
The present invention relates to a kind of holographic false proof printing industry material, particularly a kind of false proof electrochemical aluminum paint.
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 prodn 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 or blanching seal operation on coating, to add the holographic laser anti-counterfeiting information layer again, graph text information is transferred to the stock surface accomplish whole process of production; These coating are referred to as electrochemical aluminum, and produce employed false proof electrochemical aluminum at present is the mold pressing electrification aluminum of on market, purchasing at present, because temperature tolerance is poor; The heatproof interval is narrow; Cause the mold pressing scrap rate higher in the hot moulding production process after painting process is accomplished, particular case is: existing molding temperature interval is 210 ℃-220 ℃, and the mold pressing effect in the time of 210 ℃ is that better brightness is better for the glossiness of coatingsurface; Can press light; But mold pressing speed in this case is lower, and its mold pressing speed is about 30 meters of PMs, and its production efficiency is low; If under 210 ℃ of situation about not heating up, only improve mold pressing speed, then the brightness of coatingsurface is not enough, influences product appearance effect and quality; Therefore, in order to keep the brightness of coating, must when quickening, improve molding temperature during mold pressing; After improving molding temperature, when molding temperature surpasses 220 ℃, peeling haftplatte phenomenon just appears easily in the mold process.Therefore, the molding temperature interval of using always is 210 ℃～220 ℃ a scope; If molding temperature is lower than 210 ℃ then surface brightness that mold pressing is come out is not enough, if molding temperature is higher than 220 ℃ of then sticking versions of peelings easily, the interval scope of original molding temperature is less; Wayward; Cause the mold pressing scrap rate higher, cause a large amount of electrochemical aluminium work in-process to become the dull article of approximate waste product and from Production Flow Chart, roll off the production line, analyze reason; Mainly be because the adaptive temperature interval range of the electrochemical aluminum coating of mold pressing is narrow; Be unfavorable for controling of temperature, be exactly furtherly more present false proof electrochemical aluminum in existing production process because temperature tolerance is poor, the heatproof interval is narrow; The molding temperature of this electrochemical aluminum paint makes that the processing parameter index is undesirable after exceeding this TR; Cause film performance can not satisfy the next procedure requirement, be easy to generate the phenomenon of the sticking version of peeling, how to solve of the influence of temperature range narrow range processing parameter; Promptly providing the bigger electrochemical aluminum paint compsn of a kind of adaptive temperature scope to solve the defective that exists in the existing production technology, is the problem that engineering technical personnel press for solution.
