NON-SLIP SHEET, AND MANUFACTURE METHOD THEREOF, AND LABEL USED THEREOF BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a non-slip sheet, a method of manufacturing the same, and a label using the same, and more particularly, to a non-slip sheet provided with non-slip properties attached to clothing, shoes, etc., and a label using the same.

Products such as clothing, shoes, and bags need to have non-slip properties that do not slip while forming patterns on the surface.

For example, in the case of the mountain climbing clothing, the shoulder portion is a place where the belt of the climbing backpack is caught, and it is necessary to have a property that does not slip smoothly to prevent the clothes from being pushed up even in a violent movement, .

A method of printing a silicone resin on a fabric in a concavo-convex form by a method of imparting non-slip characteristics to a garment is widely used. However, in the method of printing a silicone resin on a fabric, there is a problem of peeling due to a low adhesion strength between the fabric and the silicone resin, and the silicone resin is printed on the fabric, so that the process is discontinuous and the manufacturing efficiency is low.

In addition, since the printing thickness of the silicone resin needs to be increased in order to provide a volume feeling of the non-slip portion, there is a problem that the manufacturing cost increases.

The prior art related to the present invention is disclosed in Korean Patent No. 0804040 entitled " Anti-slip fiber substrate and manufacturing method thereof, published on September 26, 2003,

It is an object of the present invention to provide a non-slip sheet having a high non-slip property which is excellent in appearance, excellent in appearance, excellent in peelability and does not slip off and is not attached to clothes, shoes or the like, and a method of manufacturing the same.

According to an aspect of the present invention for achieving the above object, the present invention provides a semiconductor device comprising a urethane layer, a silicon layer on one side of the urethane layer via a first adhesive layer, The silicon layer and the patterned layer have non-slip characteristics, including a patterned layer adhered via an adhesive layer.

The first adhesive layer includes a urethane adhesive, a hot adhesive, and a silicone adhesive.

The first adhesive layer contains 40 to 60 wt% of a urethane adhesive, 10 to 20 wt% of a hot adhesive, and 25 to 45 wt% of a silicone adhesive, based on the total weight.

The pattern layer is made of a silicon material.

The second adhesive layer becomes a silicone adhesive.

A hot-melt adhesive is attached to the other surface of the urethane layer.

Preparing a urethane sheet, applying a first adhesive to one surface of the urethane sheet and printing a silicon layer, applying a second adhesive to the upper surface of the silicon layer and printing the pattern layer, .

The first adhesive includes a urethane adhesive, a hot adhesive, and a silicone adhesive.

The first adhesive includes 40 to 60% by weight of a urethane adhesive, 10 to 20% by weight of a hot adhesive, and 25 to 45% by weight of a silicone adhesive, based on the total weight.

The pattern layer is a silicone material, and the second adhesive is a silicone adhesive.

The drying is carried out at room temperature.

The present invention relates to a process for producing a non-slip sheet by printing silicon on a urethane sheet, and the adhesion of the urethane and silicone, which are releasable and difficult to adhere to one another, is carried out by a first adhesive comprising a urethane adhesive, Enabling a robust attachment of silicon.

Therefore, there is an effect that a non-slip sheet having a function of preventing wear and being not slippery attached to clothes, shoes, etc. can be produced, since the manufacturing process is simple and the manufacturing efficiency is high,

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the non-slip sheet of the present invention comprises a urethane layer 10, a silicon layer 30 attached to one surface of the urethane layer 10 via a first adhesive layer 20, And a pattern layer 50 adhered to the upper surface of the silicon layer 30 via the second adhesive layer 40. [

In the non-stretched sheet 1, the urethane layer 10 enhances the volume feeling (thickness) of the sheet, and the silicon layer 30 and the pattern layer 50 have non-slip characteristics.

The urethane layer 10 is provided in the form of a urethane sheet. Urethane sheets are lightweight, resistant to abrasion and contamination, good in texture, flexible and resilient, and environmentally friendly, unlike PCV, which does not generate harmful substances. In addition, the urethane sheet is excellent in mechanical strength and low in cost, and is suitable for use to increase the volume feeling of the sheet.

In order to increase the volume feeling of the non-slip sheet 1 only by the silicon layer 30, the thickness of the expensive silicon layer 30 must be increased, resulting in an increase in manufacturing cost.

As the urethane sheet, a polyurethane sheet can be used.

The silicon layer 30 is formed by printing silicon on one surface of the urethane sheet. Silicone is a nontoxic, eco-friendly flame retardant material that has high mechanical strength and is resistant to water and water and is resistant to washing and does not generate harmful substances.

Silicone is also good in color and has excellent surface and gloss to provide excellent appearance. It also prevents abrasion of fabrics and fabric slip when attached to fabric. Silicon also adds a sense of quality as a non-slip sheet that is smooth and united with a urethane sheet when printed on urethane sheets.

The silicon layer 30 is provided in the form of a silicone resin and printed on one side of the urethane sheet.

When the silicon layer 30 is formed by printing on a urethane sheet, the thickness of the silicon layer 30 can be adjusted and the thickness can be uniformly formed.

Adhesion of the urethane sheet and the silicon layer 30 is performed by the first adhesive layer 20.

The first adhesive layer 20 may be formed by applying a first adhesive to the urethane sheet before the silicone resin is printed on the urethane sheet. The first adhesive acts to firmly adhere the urethane and silicone which are releasable and hard to attach to each other.

The first adhesive layer 20 includes a urethane adhesive, a low temperature adhesive, and a silicone adhesive.

The first adhesive layer 20 improves the adhesion between the urethane adhesive and the silicone adhesive, thereby enhancing the adhesion between the urethane and the silicone, and the hot adhesive acts as an adhesion promoter, thereby exhibiting excellent adhesion. The low temperature adhesives are natural drying coatings which act as adhesion catalysts for silicone and urethane.

The principle is that the hot adhesive melts the silicone to help penetrate the urethane adhesive and silicone adhesive into the silicone to activate the adhesive. In addition, the silicone adhesive helps the hot adhesive to adhere to the urethane adhesive.

If the first adhesive layer 20 is made of a urethane adhesive and a low temperature adhesive or only a silicone adhesive and a low temperature adhesive, it is difficult to adhere the urethane and silicon, and the silicone layer 30 peels off from the urethane layer 10 do.

The first adhesive layer 20 can be formed by printing a first adhesive mixed with a urethane adhesive, a hot adhesive, and a silicone adhesive on a urethane sheet.

Alternatively, the first adhesive layer 20 may be formed by applying urethane adhesive to the upper surface of the urethane sheet, applying a low temperature adhesive to the upper portion of the urethane adhesive, and then applying silicone adhesive to the upper portion of the low temperature adhesive .

The first adhesive comprises 40-60 wt% of a urethane adhesive, 10-20 wt% of a hot adhesive, and 25-45 wt% of a silicone adhesive, based on the total weight of the first adhesive.

Urethane adhesives have strong adhesion and cure at room temperature.

When the urethane adhesive is contained in an amount of less than 40% by weight based on the total weight of the first adhesive, the adhesive strength is lowered, and when it exceeds 60% by weight, the adhesive strength is lowered.

The urethane adhesive may be a urethane resin adhesive, a urethane resin solvent adhesive in which a polyurethane resin or a urethane prepolymer is dissolved in a solvent, or an adhesive containing a urethane resin emulsion as a main component.

The hot adhesive is a natural drying coating. When the hot adhesive is added in a large amount, the content of the other ingredients is relatively decreased, so that it is difficult to secure the adhesive force. Moreover, the hot adhesive can not be bonded.

As the low temperature adhesives, all commercially available naturally dryable coating agents can be used, but it is preferable that they are a penetration type silica coating agent or silicone coating agent which enhances the content of silicon.

If the low temperature adhesive is contained in an amount of less than 10% by weight based on the total weight of the first adhesive, the function of activating the adhesive force is insufficient. If the low temperature adhesive is contained in an amount exceeding 20% by weight, the content of the other components is relatively insufficient.

The silicone adhesive helps the coating adhere to the urethane adhesive and exhibits strong adhesion. Silicone adhesives are available for all types of silicone adhesives sold on the market.

If the silicone adhesive is contained in an amount less than 25% by weight based on the total weight of the first adhesive, the adhesion force between the urethane and the silicone is insufficient. If the silicone adhesive exceeds 45% by weight, the content of the other components is insufficient.

The silicon layer 30 may be formed by printing a plurality of times in order to increase the thickness of the non-slip sheet 1.

The pattern layer 50 is made of a silicon material having the same physical properties as the silicon layer 30. [ The pattern layer 50 corresponds to a figure or letter. When the pattern layer 50 is formed of a silicon material, it is excellent in adhesion to the silicon layer 30, so that shapes and characters can be precisely expressed and a core image of various products can be accurately displayed, thus providing a good appearance.

The pattern layer 50 is attached to the silicon layer 30 via the second adhesive layer 40. The second adhesive layer 40 becomes a silicone adhesive and is printed on the upper surface of the silicon layer 30 in a 1: 1 correspondence with the pattern layer 50.

That is, the second adhesive layer 40 may be applied to the upper surface of the silicon layer 30 and the pattern layer 50 may be printed on the second adhesive layer 40. Printing can employ screen bridging printing.

The silicone adhesive forming the second adhesive layer 40 can be any kind of silicone adhesive sold on the market. For example, the second adhesive layer 40 may be a primer, RTV silicone, or the like.

Since the pattern layer 50 can be applied to various characters and figures, it is possible to manufacture the non-slip sheet 1 of various designs. In addition, the pattern layer 50 has a function of securing appearance that emphasizes the core image of the product and improves the appearance.

The non-stretched sheet 1 has the urethane layer 10, the first adhesive layer 20 on the upper surface of the urethane layer 10 and the silicon layer 30 on the upper surface of the first adhesive layer 20, And a pattern layer 50 adhered to the upper surface of the silicon layer 30 via the second adhesive layer 40.

The non-slip sheet 1 is attached to the fabric through a hot-melt adhesive 60 attached to the lower surface of the urethane layer 10. In this case, the pattern layer attached to the upper surface of the silicon layer 30 and the silicon layer 30 (50) has non-slip characteristics.

Further, the non-slip sheet 1 can be produced in a state in which a hot-melt adhesive is not adhered to the lower surface of the urethane layer 10. [ In this case, the non-slip sheet 1 is attached to the fabric by sewing and is firmly attached.

(B) a step (b) of applying a first adhesive to one surface of a urethane sheet and printing a silicon layer (30), a step (b) of forming a urethane sheet on the upper surface of the urethane sheet 2 step (c) of applying an adhesive and printing the pattern layer 50, and (d) drying.

(a) is a step of preparing a urethane sheet for adjusting the volume of the non-slip sheet.

(b) is a step of applying a first adhesive to one surface of the urethane sheet, that is, the upper surface of the urethane sheet, and printing the silicon layer 30 on one surface of the urethane sheet coated with the first adhesive.

The first adhesive may be prepared by mixing 40 to 60% by weight of a urethane adhesive, 10 to 20% by weight of a low temperature adhesive, and 25 to 45% by weight of a silicone adhesive, based on the total weight.

In this case, the first adhesive maintains the liquid state in the storage state, and when it is applied, it hardens at room temperature over time and exhibits a strong adhesive force.

Alternatively, the first adhesive is applied on the top surface of the urethane sheet in an amount of 40 to 60% by weight of urethane adhesive relative to the total weight of the first adhesive, and 10 to 20% by weight of the hot adhesive is applied to the upper portion of the urethane adhesive, And then applying 25 to 45 wt% of a silicone adhesive to the total weight of the first adhesive on top of the hot adhesive.

(c) is a step of applying a second adhesive to the upper surface of the silicon layer 30 and printing the pattern layer 50 on the portion to which the second adhesive is applied.

The second adhesive and pattern layer 50 correspond in a 1: 1 ratio. Since the silicon layer 30 and the pattern layer 50 are made of the same silicon material, it is possible to securely attach the silicon layer 30 with the silicone adhesive alone.

The pattern layer 50 corresponds to the character or shape of the product and can highlight the core image of the product along with the non-slip characteristic with various characters or figures.

(d) is a step of drying after printing. Drying is carried out at room temperature. During the drying process, as the first adhesive ages, the hot adhesive component of the first adhesive interacts with the urethane adhesive and the silicone adhesive to firmly attach the silicone to the urethane.

After printing, it is necessary to dry at room temperature to cause interaction between silicone adhesive, urethane adhesive and hot adhesive, resulting in adhesion between silicone and urethane, and heat is used in the process of drying at high temperature after printing or attaching the silicone layer to the urethane layer The adhesion between the silicone and the urethane does not occur.

Drying is sufficient for one day or more, and even after heating for one day or more after drying, the adhesive force between silicon and urethane is not canceled.

In addition, the silicone adhesive, which is the second adhesive in drying, changes the silicon surface to strongly adhere the silicon layer and the pattern layer.

As shown in FIG. 2, the non-slip sheet 1 can be produced in a state that a hot-melt adhesive 60 is adhered to the other surface of the urethane layer 10. When the hot melt adhesive 60 is attached to the other surface of the urethane layer 10, the hot melt adhesive 60 is disposed to face the fabric, and heat and pressure are applied thereto using an iron or the like at the upper portion to melt the hot melt adhesive 60, (1) is firmly attached to the fabric.

At this time, it is preferable that the upper surface of the non-slip sheet 1 is covered with cloth or the like to prevent deformation or damage of the silicon layer 30 and the pattern layer 50.

As shown in Fig. 3, the non-slip sheet 1 can be produced without a hot-melt adhesive attached to the lower surface of the urethane layer 10. Fig. In this case, the non-slip sheet 1 is attached to the fabric by sewing and is firmly attached.

Fig. 4 shows a state in which Fig. 3 is applied to the mountaineering clothes.

As shown in Fig. 4, the non-slip sheet 1 is attached to the shoulders and elbows of the climbing clothing to improve the non-slip function and appearance and to prevent the wear of the fabric. The non-slip sheet 1 attached to the shoulder portion of the climbing clothing performs functions of preventing the climbing of the shoulder line of the climbing bag and the phenomenon of the clothes being pushed up by the bag, Thereby preventing the fabric from being worn.

Fig. 5 shows an example of a state in which Fig. 2 is applied to the mountaineering.

As shown in Fig. 5, the non-slip sheet 1 can be clipped using a laser or the like so as to include only a pattern or a figure, and then attached to the shoulder or elbow of the climbing gear.

In the case where the non-slip sheet 1 is attached to the mountain climbing cloth by cutting off only a part having a pattern or a figure, it is possible to provide a novelty in the design part as compared with the case where the entire non-slip sheet 1 is attached to the mountain climbing cloth.

In addition, when the non-slip sheet (1) is attached to a mountain climb by cutting out only a part having a pattern or a figure, it can be used as a label for highlighting the brand name or image of the product. In the case of attaching to a mountain climb, only a part with a pattern or a pattern is cut. In the case of attaching to a mountain climb, a hot melt adhesive method or a sewing method can be applied.

Table 1 shows the adhesive force effect of the first adhesive layer for bonding the urethane layer and the silicon layer.

For the reference, the adhesion between the urethane layer and the silicon layer was carried out by applying a first adhesive to one surface of a urethane sheet and printing a silicon layer. After the printing, Examples 1 to 7 and Comparative Examples 1 to 12, The peeling test was conducted after drying for one day.

Comparative Example 13 was dried at a high temperature of 100 캜 after printing.

<Adhesiveness>

○ ○: most excellent, ○: excellent, Δ: normal, ×: poor

As a result of the test, peeling did not occur after adhesion in the range of 40 to 60% by weight of the urethane adhesive, 10 to 20% by weight of the hot adhesive, and 25 to 45% by weight of the silicone adhesive, and 50% by weight of the urethane adhesive, , And the adhesive strength was the highest at 35 wt% of the silicone adhesive.

In the case of Comparative Examples 1 to 4 in which the urethane adhesive contained less than 40% by weight or exceeded 60% by weight, the adhesive strength was lowered and some peeling or total peeling occurred.

In the case of Comparative Examples 5 to 8 in which the low temperature adhesive agent contained less than 10% by weight or contained more than 20% by weight, it was difficult to secure the adhesive strength, and all peeling occurred.

In the case of Comparative Examples 9 to 12 in which the silicone adhesive contained less than 25% by weight or exceeded 45% by weight, it was difficult to secure the adhesive strength, and some peeling or total peeling occurred.

Comparative Example 13 satisfied the weight range of the first adhesive of the present invention at 50% by weight of a urethane adhesive, 35% by weight of a hot adhesive, and 35% by weight of a silicone adhesive, but silicone did not adhere to the urethane sheet due to high- It has been confirmed that the high temperature drying of the urethane sheet after printing the silicone through the first adhesive causes the adhesive force of the first adhesive to disappear.

However, the adhesive strength of the first adhesive did not disappear even after high-temperature treatment was performed after the adhesive strength of the first adhesive was exerted after the silicone was printed on the urethane sheet through the first adhesive and dried at room temperature.

Experimental results show that the first adhesive for bonding urethane and silicone satisfies 40 to 60% by weight of a urethane adhesive, 10 to 20% by weight of a low temperature adhesive and 25 to 45% by weight of a silicone adhesive, Drying at room temperature for more than one day is important for exhibiting the adhesive strength of the first adhesive.

As described above, in the present invention, silicone having a releasing property to the urethane sheet is firmly attached using a first adhesive including a low temperature adhesive serving as an adhesion promoter, and a silicone layer is formed on the urethane sheet by a printing process, There is an advantage that not only the provision of the sheet is simple but also the manufacturing efficiency is enhanced.

In addition, since the pattern layer is formed by using silicon of the same material on the upper part of the silicon layer, it is possible to precisely express shapes and characters due to high adhesion force, and it is excellent in flexibility and restoring force, Sheets and labels can be produced.

In addition, the manufactured non-slip sheet is attached to clothing, shoe, bag, etc. to provide a non-slip characteristic which prevents slippage and abrasion, and can be used for highlighting an image of a product or distinguishing a product when used as a label.
