Technical field

The invention belongs to 3D grating technology fields, and in particular to a kind of process of cigarette 3D raster print product.

Background technique

3D printing, is called stereosopic printing, typically refers to 3 D grating printing.It can using a kind of simulation human eye spacing The principle for generating space parallax, by different angle, the pixel record of different levels on photosensitive material, then answering by grating material Close, in three-dimensional stereoscopic effect or even virtual reality being presented on two-dimensional flat image by this approach, people without Any tool directly can experience to clear and definite the marvellous enjoyment of stereoscopic picture plane by eyes observation.3D stereoscopic print and 3 dimensional drawing is the same to can't see stereoscopic effect on computers, but after stereoscopic print prints, due to grating material The particularity of material can see stereoscopic effect without wearing anaglyph spectacles.

The principle of stereosopic printing is exactly to simulate two spacing of people, is shot from the degree at left and right eye difference angle, by left and right pixel It is recorded on photosensitive material, when viewing, left eye sees the print that left pixel, right eye see right pixel, produce according to this principle Brush product are known as stereosopic printing.Stereosopic printing have can realistically reconstructed object, due to original copy be shape-designing or scene shot and At, printed matter is typically chosen in good art paper and oil resistant ink print, so glossiness is good, it is bright-colored, it is not easy to take off The features such as color, printing product surface cover one layer of concave-convex cylindrical mirror shape original screen panel, can be with the stereoscopic effect of direct viewing panorama. The effect of stereo-picture must be embodied by display technology.

Cigarette is more common consumables, very common in daily life, and cigarette pack can be good at improving cigarette Class improves selling price.The common printing technology of Cigarette pack is flat stamping, and stereoscopic effect is poor, and glossiness is low, and color It is dull.

Summary of the invention

In view of this, the present invention provides a kind of process of cigarette 3D raster print product, the wearability of ink is good, solidifies Speed is fast, and the grating layer prepared has enough intensity, will that present techniques apply to cigarettes is durable with can be improved its in packing box Property.

The present invention is a kind of process of cigarette 3D raster print product, and used grating ink includes by weight Following components: 15-23 parts of ethoxylated trimethylolpropane triacrylate, 7-12 parts of polyurethane, caprolactone modification epoxy 33-55 parts of acrylate polymer, 0.3-0.48 parts of dimethyl silicone polymer class surfactant, the sweet ammonia of N- methylacryloyl 1-2.5 parts sour, 5-8.6 parts of anti-wear additive, 5-8.5 parts of 1,6 hexanediol diacrylate, (2,4,6- trimethylbenzoyl Base) 2.5-5.7 parts of diphenyl phosphine oxide, it further include methyl methacrylate, the additive amount of methyl methacrylate is 5-8 parts.

Ethoxylated trimethylolpropane triacrylate is trifunctional function monomer.It can be used as dilute dose of reactivity, be used for In radiation curable coating, glossy black and adhesive.It has suitable viscosity and excellent dissolution while with high activity Power.And can assign cured film good flexibility, the shrinking percentage of cured film is reduced, the adhesive force to substrate is improved, improves intensity.

The resin or binder of high-crosslinking-degree are beneficial to provide the later hardness of ink solidification, shorten the cured time, Binder used in the present invention is the binder of a variety of high polymers mixing.By taking polyurethane as an example, polyurethane is a kind of macromolecule Material.It is widely used in daily life such as the paint and coating in furniture, polyurethane performance adjustable extent is wide, adaptability By force, wearability is good, and adding suitable polyurethane can effectively enhance in whole intensity, the viscosity of adjustment ink flowing.Poly- two Methylsiloxane class surfactant is the mobility in order to adjust ink, the process that good mobility can be such that ink uses Middle operation is more convenient, is conducive to the thickness for reducing film forming as far as possible while guaranteeing enough hardness.With double bond content in molecule Increase, the crosslinking rate of film will increase, and curing rate will be accelerated, and the unsaturated group in molecule is crosslinked mutually, be applied by liquid Layer becomes solid-state coating.Ethoxylated trimethylolpropane triacrylate, N- methylacryloyl glycine are introduced, is accelerated dry Dry cured speed.

Preferably, used grating ink includes following components by weight: ethoxylated trimethylolpropane three 20 parts of acrylate, 10 parts of polyurethane, 40 parts of the epoxy acrylic ester polymer of caprolactone modification, dimethyl silicone polymer class table 0.44 part of face activating agent, 2 parts of N- methylacryloyl glycine, 7 parts of anti-wear additive.

The anti-wear additive of addition can be improved the wearability for solidifying ink layer later, and the wearability additive is fluorine wax Powder, organosilicon levelling agent, fluorine wax powder, the weight ratio of organosilicon levelling agent are 1:1-2.Wearability can be improved in fluorine-containing wax powder, has Surface hardness and Scratch Resistance can be improved in machine silicon levelling agent.Fluorine-containing wax powder can be polytetrafluoroethylwax wax powder, polytetrafluoroethylene (PTFE) Wax powder is ultra-fine differentiation wax, and the transparency is good, and not delustring is added in ink and wearability can be improved, simultaneously added with machine silicon Levelling agent, can increase the smooth degree of layer of ink after solidifying, and smoothness improves wearability, the anti-scratch ability of layer of ink.

The raw material used be it is pollution-free, no harmful substance distributes, very safe, can satisfy the use mark of cigarette.

A kind of process of cigarette 3D raster print product, comprising the following steps: carry out the printing of colour image, printing can In a manner of using offset printing, the printing of colour image will have very high precision, just can guarantee the acuteness of dynamic pattern in this way；Light The production of grid mold；Grating ink is printed on the body paper for be printed on pattern layer；Grating mold is put on grating ink layer, one 3D grating ink layer is prepared under constant-pressure；It is demoulded after solidification, the cured time is about 3-4h, and cured temperature is 100-120℃。

The grating ink layer with a thickness of 1.5-2.2mm, grating ink layer surface layer be protrusion disposed in parallel thoroughly One of mirror, cylindrical lenses.

Beneficial effects of the present invention:

(1) a variety of high polymers of the binder used are combined with each other, including three acrylic acid of ethoxylated trimethylolpropane Ester part, polyurethane part, the epoxy acrylic ester polymer of caprolactone modification, 1,6- hexanediyl ester, these high polymers The degree of polymerization it is very high, can accelerate ink film solidification after guarantee its hardness；

(2) ethoxylated trimethylolpropane triacrylate, N- methylacryloyl glycine are introduced simultaneously, are accelerated dry solid The speed of change；

(3) anti-wear additive is added, the fluorine-containing wax powder used, organosilicon levelling agent can make the ink film of grating ink very smooth, With very high wearability, anti-scratch ability.
