Hereinafter, a glass panel of a magnet-attaching method having a digital printing material according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

Figure 1 is a cross-sectional view showing a magnet-attached glass panel having a digital printing material according to an embodiment of the present invention, Figure 2 is a digital printing of a magnet-attached glass panel having a digital printing material according to an embodiment of the present invention It is a sectional view showing the material.

Specifically, as shown in Figures 1 and 2, the glass panel of the magnet-attaching method having a digital printing material according to an embodiment of the present invention is a glass layer 100, the adhesive layer 200, the digital printing material 300, It may include a composite panel 400 and the magnet plate 500.

First, the glass layer 100 may be formed of a material having a flat surface and excellent hardness and transparency. Preferably, the glass layer 100 may be formed of one of ordinary glass, tempered glass, and special glass subjected to heat treatment and surface treatment.

In addition, the glass layer 100 is formed to a thickness of 0.2 ~ 0.5T, preferably may be formed of a 0.4T thickness.

At this time, when the thickness of the glass layer 100 is less than 0.2T, the hardness of the glass layer decreases, and when the thickness of the glass layer 100 exceeds 0.5T, the transmittance of the glass layer 100 decreases, so that the light reflectance This increases, and the overall thickness of the glass panel becomes thick, which may cause a problem that it is not easy to attach to the wall surface.

Accordingly, damage to the surface of the glass panel is prevented by residues generated from the outside, and the light reflectance is reduced.

Next, the adhesive layer 200 is formed on the back surface of the glass layer 100 and may be formed of a material having viscoelasticity.

Accordingly, when the glass layer 100 is cracked or damaged, the glass fragments are prevented from splashing outward.

Further, the adhesive layer 200 may be formed of one or two or more of vinyl acetate, acrylic, polyurethane, polyester, polyamide, and epoxy homopolymer and copolymer transparent adhesives.

In addition to this, the adhesive layer 200 may include 15 to 20 parts by weight of metallocene polyethylene (m-PE) with respect to 100 parts by weight of the epoxy-based homopolymer.

Metallocene polyethylene (m-PE) is a composition prepared using a metallocene catalyst, and is characterized by having excellent moisture resistance.

Accordingly, since it has a moisture-proof effect, it has an effect of preventing moisture from penetrating into the digital printing material 300 on the lower surface.

At this time, if the metallocene polyethylene (m-PE) is less than 15 parts by weight, moisture may be penetrated due to low moisture resistance, and if it exceeds 20 parts by weight, the adhesive layer 200 may increase in flexibility and decrease viscosity. have.

In addition, the adhesive layer 200 is formed to a thickness of 0.1 ~ 0.5T, preferably may be formed to a thickness of 0.25T.

At this time, when the thickness of the adhesive layer 200 is less than 0.1T, the adhesive strength with the glass layer 100 decreases, and when it exceeds 0.5T, there may be a problem that the sharpness of the printed material printed on the digital printing material decreases. .

In addition, it is preferable that the adhesive layer 200 has an adhesive strength of 10 N / 10 mm or more.

At this time, when the strength of the adhesive layer 200 is less than 10N / 10mm, there may be a problem that the adhesive strength with the glass layer 100 is lowered.

Next, the digital printing material 300 is formed on the back surface of the adhesive layer 200, it is possible to implement the design of the glass panel by digital printing.

In addition, the digital printing material 300 is formed to a thickness of 0.2 ~ 0.3T, preferably may be formed to a thickness of 0.25T.

At this time, when the thickness of the digital printing material 300 is less than 0.2T, the strength of the digital printing material is low and the workability is lowered. When it exceeds 0.3T, the overall thickness of the glass panel is thickened, which is not easy to attach to the wall surface. Problems may arise.

In addition, the digital printing material 300 may include a base layer 310, a printing layer 320 and a hard coating layer 330.

The base layer 310 is a polyethylene terephthalate (PET) film, a polyether sulfone film, a polyacrylic resin film, a polyurethane resin film, a polyester film, a polycarbonate film, a polysulfone film, and a polymethylpentene film that guarantees transparency. , Polyether ketone film and (meth) acrylonitrile film.

However, since this is only an embodiment of the present invention, it may be formed of various materials having transparency, such as a transparent polymer film fabric.

Further, the printing layer 320 may be formed of one or more of acrylic resin, polyurethane resin, polyester resin, polyvinyl chloride (PVC) resin, ethylene vinyl acetate (EVA) resin and polyvinyl alcohol (PVA) resin. You can.

However, since this is only an embodiment of the present invention, in addition to this, the ink printed on the printing layer 320 may be formed of a resin material that is absorbed and received.

At this time, it is preferable to use Latex ink as the ink to be printed on the print layer 320. Accordingly, since harmful substances are not released, it is not only environmentally friendly, but also has an excellent color preservation effect.

The hard coating layer 330 may be formed on the back surface of the base layer 310 to improve the hardness of the digital printing material 300.

Further, the hard coating layer 330 may be formed of one or more of an acrylic compound, a urethane compound, an epoxy compound, a siloxane polymer, and an oligomer.

However, since it is only an embodiment of the present invention, it may be formed of various ultraviolet curing resins.

Further, the hard coating layer 330 may further include a silica-based filler to improve hardness.

Preferably, the silica-based filler may include 5 to 20 parts by weight based on 100 parts by weight of the entire composition of the hard coating layer 330.

At this time, when the silica-based filler is less than 5 parts by weight, the increase in hardness is minimal, and when it exceeds 20 parts by weight, the hardness is sufficiently increased, so that a problem in that manufacturing efficiency may be lowered may occur.

Next, the composite panel 400 is formed on the rear surface of the digital printing material 300, preferably, may be formed in a frame shape that can accommodate the magnetic plate 500.

In addition, the composite panel 400 may be formed of an aluminum lightweight panel.

However, since this is only an embodiment of the present invention, it may be formed of various lightweight materials.

In addition, the composite panel 400 is formed in a thickness of 2.5 to 3.5T, and preferably may be formed in a 3T thickness.

At this time, when the thickness of the composite panel 400 is less than 2.5T, there is a risk of damage due to low strength of the panel, and when it exceeds 3.5T, the weight of the glass panel becomes heavy and it is difficult to attach to the wall. You can.

Next, the magnet plate 500 is formed on the rear surface of the composite panel 400, preferably, may be formed in a structure that is inserted into the composite panel 400.

However, since this is only an embodiment of the present invention, it may be formed in a form attached to the rear surface of the composite panel 400.

In addition, the magnet plate 500 may be formed of one of a rubber magnet plate and neodymium.

However, since this is only an embodiment of the present invention, it may be formed of various materials having magnetic properties.

Accordingly, it is possible not only to easily construct the glass panel of the present invention without specialized technology, but also has the effect of being freely detachable from the wall surface to which the magnet is attached, such as an iron plate.

In addition, the magnet-attached glass panel having a digital printing material according to an embodiment of the present invention may further include an anti-coating layer 600.

The anti-coating layer 600 is formed on the front surface of the glass layer 100, and may be formed of calcium fluoride (CaF ₂ ) to prevent light reflection.

In addition, the anti-coating layer 600 is formed to a thickness of 0.5 ~ 1T, preferably may be formed to a thickness of 0.8T.

At this time, when the thickness of the anti-coating layer 600 is less than 0.5T, the light anti-reflection effect is not sufficiently exhibited, and when it exceeds 1T, there may be a problem that the sharpness of the printed material printed on the digital printing material is deteriorated.

Hereinafter, the present invention will be described in more detail with reference to examples, but these are merely for illustrating preferred embodiments of the present invention, and the examples are not intended to limit the scope of the present invention.

[ Example  One]

An adhesive layer formed of a 0.25T thick polyurethane-based adhesive was formed on the back side of the glass layer formed of 0.4T thick tempered glass.

On the front of the base layer formed of a polyethylene terephthalate (PET) film, a printing layer formed of an acrylic resin printed by an inkjet method is formed using a Latex ink, and a silica-based filler on 100 parts by weight of an acrylic compound on the back surface. Digital coating material was prepared by forming a hard coating layer containing 10 parts by weight.

A digital printing material having a thickness of 0.25T was formed on the back side of the adhesive layer.

A 3T thick aluminum lightweight composite panel was formed on the back side of the digital printing material.

A magnet plate made of a rubber magnet plate was formed on the rear surface of the composite panel to produce a magnet-attached glass panel having a digital printing material.

[ Example  2]

It was prepared as in Example 1 except that the adhesive layer was formed containing 15 to 20 parts by weight of metallocene polyethylene (m-PE) relative to 100 parts by weight of the epoxy-based homopolymer.

[ Example  3]

On the upper side of Example 1, a 0.8T thick calcium fluoride (CaF ₂ ) anti-coating layer was formed to prepare a magnet-attached glass panel having a digital printing material.

[ Comparative example  One]

It was prepared as in Example 1, except that the thickness of the glass layer is formed of 0.6T.

[ Experimental example  1] Moisture resistance measurement

To measure the moisture permeability of Examples 1 and 2, moisture permeability was calculated by measuring the moisture permeability sheets of Examples 1 and 2 by the method of moisture permeability test of JIS Z 0208 moisture proof packaging material.

Measurement results are shown in Table 1 below.

Moisture permeability (g / m ²  * 24hr ) Example  One 0.5 Example  2 0.2

As shown in [Table 1], it can be seen that Example 2 has a lower moisture permeability than Example 1. Accordingly, metallocene polyethylene (m-PE) based on 100 parts by weight of the epoxy-based homopolymer It can be seen that the adhesive layer containing 15 to 20 parts by weight has high moisture resistance.

[ Experimental example  2] Light reflectance measurement

In order to measure the light reflectance of Examples 1 and 3 and Comparative Example, front and side reflectivity was measured. The reflectance was measured by simulation using an LCD master (Shintech).

Measurement results are shown in Table 2 below.

Reflectivity ( % ) face Side (60˚) Example  One 0.11 0.54 Example  3 0.10 0.42 Comparative example  One 0.12 0.72

As described in [Table 2], it can be seen that the glass panels according to Examples 1 and 3 had low reflectivity at the front and side surfaces compared to the glass panels according to Comparative Example 1. Further, Example 3 is an example. Since it exhibits a reflectivity lower than 1, it can be seen that the anti-reflective layer of the present invention has an anti-reflective effect.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, it will be understood that the present invention may be implemented in other specific forms by those skilled in the art. Therefore, the above-described embodiment is illustrative in all respects and is not limiting.
