Experimental example:
the thin-coat epoxy resin paint was selected as a control group one, the modified asphalt paint was selected as a control group two, and the pearlescent varnish of the present application was selected as an experimental group.
The following table is the test method and standard for three groups of paints:
and selecting three polyethylene films with the same area, material and specification as the experimental object.
The experimental requirements are as follows: the three groups of paint vehicles are respectively used for spraying the polyethylene film, and the specific detection data are as follows:
the following table shows the results of the three paint groups:
by combining the above table, the comparison of the first control group, the second control group and the experimental group is carried out, and the measured data of the pearlescent varnish serving as the experimental group is superior to those of the first control group and the second control group, so that the pearlescent varnish is more suitable for being applied to the laser transfer film as tobacco wrapping paper compared with the first control group and the second control group.
The technical effects of the invention are mainly reflected in the following aspects: this radium-shine transfer membrane has the pearl varnish through the surface coating at the thin layer, not only can prolong the oxidation rate of radium-shine transfer membrane, can also make the reflection light source of radium-shine transfer membrane stronger, can improve anti-counterfeit performance, in addition, this pearl varnish is by fluororesin, acrylic resin, wax powder, non-superficial type aluminium silver thick liquid, elasticity fluorocarbon emulsion, titanium white powder, phosphate, the thick liquid that mica pigment and hydroxyethyl cellulose made, through cyclohexanone, n-butyl alcohol, triethyl hexyl phosphoric acid and lauryl sodium sulfate disperse, thicken through the alginate, improve anti-oxidant performance through combining with the grease at last, make the pearl varnish that makes have anti-oxidant effect good on applying radium-shine membrane, the advantage that the color is bright and anti-counterfeit performance is high, be applicable to cigarette packaging.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
