Its advantages are high solidifying speed, thin thickness of Al layer (0.03-0.05 microns) and natural degradable.
Description
Technical field the present invention relates to the laminar product be made up of paper or cardboard in fact, relates in particular to the preparation method of the aluminium-plated paperboard of a kind of vacuum.
The aluminium-plated paperboard of background technology vacuum is a kind of new packaging material that is widely used in medium and high-grade external packings such as medicine, food, cosmetics and cigarette, tea, wine, is progressively replacing traditional aluminium foil paperboard and polyester paperboard.Its surfacing is bright and clean, and color and luster is even, and its glossiness, smoothness, folding strength, elasticity, adhesive ability, ultraviolet resistance printing performance, and antiforge function are than other like product excellence.But, being subjected to existing preparation method's restriction, vacuum aluminizing paperboard can only be a five-layer structure, has the defective of poor efficiency, high consumption.
Summary of the invention is the defective that remedies prior art, and the present invention proposes the preparation method of the aluminium-plated paperboard of a kind of vacuum, and the technical scheme of employing is as follows:
The preparation method of the aluminium-plated paperboard of this vacuum is characterized in that pretreatment is arranged successively, secondary coating, spraying plating aluminium lamination and surperficial painting process:
Above-mentioned pretreatment process is, under 60～150 ℃ of oven for drying temperature, 60～150 meters/minute conditions of reticulate pattern coating machine running velocity, will with paper substrate face, varnish that the ultraviolet film adhesion value is good, be uniformly coated on the paper base material, its dry-coated amount is 0.5～3.0 gram/sq m, and is standby.
Above-mentioned secondary painting process is, under 60～150 ℃ of oven for drying temperature, 60～150 meters/minute conditions of reticulate pattern coating machine running velocity, with low viscosity (LV), high solids content aluminium paint, be uniformly coated on through on the base material of pretreatment process, aluminum membranous layer is managed to make do in generation, and its dry-coated amount is 2～15 gram/sq ms.
Above-mentioned spraying plating aluminium lamination operation is, is not less than 1 milli handkerchief in vacuum aluminum-coated machine degree of vacuum, and under vacuum aluminum-coated machine running velocity 2～12 meter per second conditions, with the aluminium molecule of high temperature melting evaporation, evenly spraying plating is made the spraying plating aluminium lamination on the base material through the secondary painting process.
Above-mentioned surperficial painting process is; under 60～150 ℃ of oven temperatures, 60～150 meters/minute conditions of reticulate pattern coating machine running velocity; can shield or the coating of customer requirement being adapted to painted and printing; be uniformly coated on the base material through the secondary painting process; make the aluminium protective cover; also be dyed layer, its dry-coated amount is 0.5～3.0 gram/sq m, promptly is goods.The further feature of this vacuum evaporating aluminium lamination official form for filing a lawsuit preparation of plates method is: the varnish in above-mentioned pretreatment process can be vinyl chloride-vinyl acetate resin, also can be acrylic resin, can also be polyester and modified version resin thereof.
In above-mentioned secondary painting process aluminium paint, can be the ultraviolet light oil polish of acrylic compounds, also can be the ultraviolet light oil polish of polyesters, can also be the ultraviolet light oil polish of polyurethanes.
In above-mentioned spraying plating aluminium lamination operation, can carry out laser holographic molding and handle, promptly under 100～200 ℃ of temperature, will use the grating version of laser beam machining, be replicated in the substrate surface of process secondary painting process through molding apparatus.
After above-mentioned surperficial painting process, can increase postprocessing working procedures according to additional requirement to goods.
The further again feature of this vacuum evaporating aluminium lamination official form for filing a lawsuit preparation of plates method is:
Above-mentioned ultraviolet light glazing oil viscosity is that (Cha Shi 4 in 10 ± 1 seconds
#Carry the cup, 25 ℃), solids content 〉=95%.
Above-mentioned postprocessing working procedures is, under 50～150 ℃ of oven for drying temperature, 50～150 meters/minute conditions of reticulate pattern coating machine running velocity, the polyvinyl alcohol modified resin coating DNCP-200 that will have the typing function of preserving moisture, be uniformly coated on through on the base material of surperficial painting process, dry-coated amount is 0.3～2.0 gram/sq m.
As the paper base material of substrate be paper smooth, be applicable to the ultraviolet light coating and quantitatively be the art post paperboard of 40～230 gram/sq ms; the thickness of middle spraying plating aluminium lamination is 0.03～0.05 micron; what manage to make do aluminum membranous layer quantitatively is 2.0～15.0 gram/sq ms, and as the aluminium protective cover of panel quantitatively is 0.5～3.0 gram/sq m.
The present invention's beneficial effect against existing technologies is, in paper in reel substrate surface coating low viscosity (LV), the high molecular polymer of high solids content aluminium paint, and adopt photocuring technology infrared and that shortwave combines, the coating curing rate is fast, homogeneous in the table, complete curing generates the Polymer that can reach 12 micron thickness and manages to make do aluminum membranous layer in the time of several seconds, what not only generate manages to make do aluminum membranous layer smooth, light, index such as adhesive ability and elasticity is good, solvent residual amount is extremely low, be fit to vacuum evaporating aluminium lamination thereon, and be suitable for being coated with in the mechanical automation of paper in reel substrate surface, allow disposable coating weight relatively large, manage to make do the aluminum membranous layer maximum quantitatively can reach 15 gram/sq ms, can cover the part defective on paper base material surface, improve the surface quality of goods.Goods of the present invention are four-layer structure, lack one deck than the five-layer structure that has the similar aluminium-plated paperboard of transfer now, can shorten preparation process, reduce material loss.The aluminum foil thickness of general aluminium foil applying goods is more than 6 microns, and aluminium foil can not natural degradation, and the aluminium spraying layer thickness of goods of the present invention only is 0.03～0.05 micron, the energy natural degradation, can save bauxite resource in a large number, reduce feed stock cost, especially free from environmental pollution.In addition, the glossiness of goods of the present invention, smoothness, folding strength, elasticity, anti-boiling hot property, resistance to abrasion, and UV resistant printing performance all improve significantly.
