HOT MELT ADHESIVES AND HOT MELT LABEL SHEET MANUFACTURE METHOD AND HOT MELT COATING METHOD USED IT AND HOT MELT LABEL SHEET}

The present invention relates to a hot melt adhesive and a method for manufacturing a hot melt label paper using the same, and a device thereof, and in particular, to provide a hot melt adhesive having excellent adhesive property, and to apply a hot melt adhesive to paper (printing paper) or a release paper, and then to apply a trademark or a logo. The printed label is a hot melt label paper manufacturing method, a hot melt coating device and a hot melt label, which is easily attached to a carpet or the like by heat welding, and is inexpensive to manufacture.

In general, when a carpet or a carpet-like product is manufactured and sold, a label for identification is attached by labeling or designing a logo or description of the product.

At this time, the label is attached in various forms and ways. Usually, a label or pattern is printed on a textile or PVC sticker, and then the label fabric printed on the label or pattern is attached to the product using a sewing machine, a needle, a sticker, and the like. The way prevailed.

In particular, in the case of the carpet (3) and the like as shown in Figure 1 was used a lot of methods to print a label or pattern on the fabric made of fibers or to attach a label (L) weaved (label made by weaving a trademark thread), Thus, when the label (L) printed on the carpet (3) is conventionally used to affix the sewing method or the adhesive method by a sticker method to a portion to which the label to be attached.

However, the labeling method by the sewing machine has a disadvantage in that it is difficult to sew by sewing machine in the case of a large product, such as carpet (3), not only the workability falls but also the label drops when the thread is broken.

In addition, when the label is attached by the sticker method, the adhesive function is weakened during washing, and thus the adhesive strength is reduced, and the label is easily dropped.When dust is accumulated on the sticker magnetic field, the sticker can be easily detached.When the label is dropped, the adhesive part becomes dirty. There was this.

Existing label fabrics were applied by coating the coating made by mixing white pigment for clearness of printing and printing on the back of the woven space, and then applying hot melt, but the nature of the fabric (satin) is soft and flexible. Therefore, the price is expensive due to many difficulties in flat processing coating and the cost increase due to productive degradation, and it is not suitable as a carpet label used flatly spread in a living room or a room.

The present invention has been made in view of the above circumstances, and provides a hot melt adhesive having excellent heat sealability and adhesiveness.

Another object of the present invention is to apply a hot melt adhesive on a paper (printing paper), and then apply a label or printed logo on the label by heat welding. It is an object of the present invention to provide a label paper manufacturing method and a hot melt coating device.

Still another object of the present invention is to provide a hot melt label paper having a hot melt adhesive attached to the back side of a printed paper.

Hereinafter, the present invention will be described in detail with the accompanying drawings.

2 and 3 are a perspective view and a cross-sectional view showing a label for a carpet according to the present invention, the label for the carpet (L) is a label or pattern on paper (1), such as general printing paper, snow art paper, art paper, white paper, imitation paper, etc. The hot melt adhesive 2 described later is applied to the printed back surface to form a hot melt portion 2.

The thickness of the hot melt adhesive applied to the hot melt portion 2 has a thickness of about 0.10 mm to 0.20 mm so that the adhesive force of the hot melt adhesive is firmly attached to the carpet.

In addition, the present invention is a hot melt adhesive applied to the paper (1) has a heat-melt, it is a solid material at room temperature, but when heated by an electric device, for example, iron, heat press, etc. will be dissolved in a liquid or fluid state to have an adhesive force .

Such hot melt hot melt adhesives are different from other types of adhesives that become solid by evaporation or removal of the solvent or by polymerization. And the heat-melt hot melt adhesive used in the present invention uses a hot melt that is melted to change to a liquid state when the heat of about 65 ℃ ~ 90 ℃.

Next, the manufacturing method of the hot melt adhesive of this invention is demonstrated.

Solvent doluene or spinol is mixed and heated in a liquid state at a rate of 3 kg of ethylene vinyl acetate per liter. At this time, ethylene vinyl acetate contains 60% to 70% of the total mixture.

As such, when ethylene vinyl acetate in the form of a solid granule is mixed with the solvent toluene and heated, the ethylene vinyl acetate is melted and mixed with the solvent at a melting point of 120 ° C.

Next, when it is confirmed that all of the ethylene vinyl acetate is dissolved, it is dissolved in the melting point of 125 ° C to 130 ° C by adding 0.5% to 0.7% of phenolic resin and heating.

When the phenol resin melts, it adds 13% to 15% of Lano Place MP45 (manufacturer: Whist, Germany) and 0.5% to 0.7% Kps wax (manufacturer: Whist, Germany). It is dissolved and mixed at ℃.

Once the lanoflex and Kps wax are melted, 0.5% ~ 0.7% of nylon powder is added at the end. When heated, it melts and melts at 80 ℃.

When the hot melt melts well, stirs, mixes, solidifies into a shape of a suitable size while slowly cooling, and stores the small granules or thinly cut and packaged them. The hot melt adhesive is applied to paper by the method described below and used as a label. There is an electric heating device that will be dissolved again in a liquid state to use.

here,

(A) Kps wax has a property of eliminating stickiness (stick phenomenon), if less than 0.5% due to stickiness in the hot melt portion, workability is very uncomfortable due to stickiness in the process of printing and other processes.

In addition, if Kps wax is more than 0.7%, it is inconvenient due to slipping when cutting the printed matter and completing printing work and other printed matters. In particular, when cutting several sheets when cutting, the cutting is caused by slippage and the cutting is not performed well.

(B) Phenol resin has the property of melting and sticking when labeling the carpet by ironing, etc., and mixing the adhesive with the adhesive.

When the phenol is less than 0.5%, the adhesive penetrates into the carpet cloth, leaving only paper on the label, so that the carpet and label are easily released.

When the carbonic acid balance is more than 0.7%, the adhesive property of the cloth becomes weak and it is easily released from the carpet.

(C) Nylon powder is an adhesive reinforcing agent. It is an adhesive to soften hard adhesives. It softens slippery properties and makes matte adhesives matte. When it is 0.5% or less, it does not maintain flexibility and stickiness properly. It becomes sticky.

When the nylon powder is 0.7% or more, it becomes too slippery and hard, and the liquid state becomes stiff, which makes it difficult to apply.

(D) Lanofex prevents the end of curling due to hot melt coagulation when the hot melt portion and paper are combined, which facilitates the insertion of the coating device and functions to flatten and flatten.

When the Llanoplex is less than 13%, it is not flattened and is not flattened, so it is frequently caught in the machine during printing, resulting in deterioration of production. It is very difficult to produce and leads to degradation of production.

If Lanofex is more than 15%, it becomes hard and breaks, and weakens the adhesive strength of the hot melt.

(E) Ethylene vinyl acetate is a composition that adjusts the volume so that it can be well-balanced in terms of adhesiveness and sticking property, and when the ethylene vinyl acetate is less than 60%, the hot melt hardens, breaks and dissolves in liquid. It takes time.

When the ethylene vinyl acetate is 70% or more, the flexibility is increased, and when printing, printing is generally performed while pressing the pressure in each roller of the printing press.

On the other hand, in the present invention, the petroleum resin, which can be replaced with the phenolic resin, functions as an adhesive reinforcing bar, and when it is 0.3% or less, the adhesive strength is weak, so that it is absorbed by a carpet or a lug and is insufficient in an amount capable of maintaining the adhesive strength, thereby easily leaving. On the other hand, when more than 0.7%, the adhesive strength is strong, but the properties of other drugs are lowered, so as to contradict the interaction with each other, the function of hot melt adhesion is weakened and the properties of other drugs are lowered, thereby lowering the function of the label.

Next, a method of applying hot melt to the paper 1 will be described with reference to the hot melt label paper manufacturing apparatus of FIG. 4.

The hot melt adhesive of the present invention, which is present as solid granules, is introduced into the hot melt reservoir 18 of the hot melt supply unit M.

The heat-melt hot melt adhesive according to the present invention is melted in the liquid state in the reservoir 18, and then prepared by applying a suitable amount of white pigment (per sugar) to mix the hot melt.

Thereafter, the hot melt coating apparatus for manufacturing a hot melt label for carpet according to the present invention may be operated.

Here, the operation process of the hot melt coating device, one of the paper (1) selected from snow art paper, art paper, copy paper, imitation paper, etc., which are wound around the supply roller 11 is rolled paper (1) Loosen) to move toward the guide roller (12).

Then, the paper 1 is passed through the application rollers (14, 15) while being guided by the two guide rollers (12, 13), at this time hot melt injection is installed in the hot melt supply portion (M) in the hot melt reservoir (18) The apparatus 17 is operated to supply the liquid hot melt from the hot melt supply device 50 onto the paper 1 on the application roller 15 and drop it to adjust the thickness of the hot melt application and to the thickness control roller 16. Is applied evenly to a suitable thickness.

The paper 1 coated with the hot melt is guided by the guide roller 19, and is dried by blowing by the driving of the blowing fan P while passing through the drying unit H, and one side of the paper 1 due to the hot melt. As the hot melt turns into a solid, a label of the carpet is formed.

And the label paper dried while passing through the drying unit (H) and the blowing fan (P) is flattened by the guide rollers (20, 21) installed in the middle of the transfer process, guide the guide roller 24 With the help of a rolled paper roller 25 to hold it evenly and uniformly wound, the packing roller 26 is rounded and packed in a proper size.

On the other hand, the hot-melt reservoir 18 and the injector 17, the hot-melt supply unit (M) containing the hot melt may be separately installed to move according to the type of work is made separately.

In addition, when the hot melt formed according to the present invention is supplied to the reservoir 18 in a solid state, as described above, a grinder is installed in the reservoir 18 together with the electric heating device to dissolve in a liquid state while rotating. It can be melted more evenly.

As described above, when the label L of FIG. 3 coated with the hot melt formed through the above operation is made according to the present invention, the product of the product to be attached to the opposite side of the paper 1 of the label applied with the hot melt through a separate operation. Printed with a trademark or logo, and then printed on gold leaf or coating to produce a variety of label products.

If the label for the carpet among the labels made in this way to be attached to the desired position of the carpet, place the carpet label in place and press it with an iron or heat press heated to 80 ° C. to 100 ° C. or more, and the hot melt part of FIG. ) Melts and attaches to the carpet, making the label firmly attached.

On the other hand, the present invention may be used in the form of a tape by laminating with a release paper (L2) as shown in FIG.

At this time, the release paper supply device 100 is replaced in place of the hot melt supply device 50 of FIG.

That is, the release paper supply device 100 is a release paper supply roller 27 for supplying the release paper (L2), the roller 28 and the guide roller (29) for peeling off and wound off the release paper (L3) attached to the release paper (L2). It includes.

5, the same or equivalent parts as those in FIG. 4 are given the same reference numerals.

In this way, the release paper L2 laminated with the label paper L1 is finally wound up on the packaging roller 26 and manufactured into a tape type.

On the other hand, in the present invention, the paper 1 used as the label paper is made of a transparent paper thinner paper or woven cloth to make the flat when hot melt fusion to prevent the back surface is reflected on the printing surface, 20% polyurethane , White pigment (per ground) 80% by weight and mixed with toluene mixed solvent therein can be a coating treatment on the back of the white base coating composition.

This prevents the white base coating from blocking the white base coating even if the skin complex to which the hot melt label is attached has a dark color.

Therefore, various colors can be added to the printing surface of hot belt labels.

At this time, if more than 20% by weight of polyurethane, the fabric becomes too brittle and relatively lack of white pigment may cause the white pigment to fall off, causing a phenomenon of non-dance.

When the polyurethane is 20% by weight or less and the white pigment is 80% or more, the adhesive strength of the polyurethane is weak, so that the white pigment can be easily released.

As described above, according to the present invention, the adhesiveness is excellent, the processing process is simple, the manufacturing cost can be reduced, and it can be easily attached to the object to be attached by heat fusion, so that labeling of relatively large products such as carpet It is advantageous for the work, and there is no problem that the adhesive part becomes dirty like the conventional sticker method. Moreover, it has the advantage that it can manage and use it by tape type.
