Description

An viscosity sheet of the multipurpose matt}

The present invention relates to a multi-purpose matte adhesive sheet and a method for manufacturing the same, in more detail, a matte ultraviolet curable coating layer excellent in handwriting and eraseability on an upper surface of a transparent plastic film, and a print layer selectively formed on a bottom surface, and then magnetic Provides a multi-purpose matte adhesive sheet in which a release layer is laminated to an adhesive layer containing components, making it easy to carry, easy to install and remove on any side, excellent in maintaining and durability of matte, and detachable magnetic material on the surface. It relates to a multi-purpose matte adhesive sheet that can also be used as a beam projector screen.

Currently used blackboards are divided into a general blackboard using chalk and a white board used as a water chalk having an aqueous characteristic or a board maca having an aqueous characteristic.

The biggest disadvantage of the general blackboard or white board is a problem that slip and erase performance is reduced when the erase after repeated writing.

In addition, the general blackboard using chalk is excellent in writing because the paint is made for the use of chalk, while the chalk is generated during writing or erasing, and much afterglow remains due to static electricity. Because the use of is repeated several times, there is a lot of difficulty in manufacturing to obtain a uniform surface, especially when the education of the use of magnets for the diversification of education, the iron plate must be used on the above board It is to make the work more difficult to be laminated to the iron plate.

On the other hand, the advantage of a blackboard used as a water chalk or water-based pen is that it is easy to be productive without generating dust when writing, but it is not economical because it is used only as a special writing instrument that is erased with water, and the clarity of writing even when used as such writing instrument is improved. In order to improve the clarity of writing by using acrylic beads having a certain shape for this purpose, the bead of the same size is not only the disadvantage of poor writing feeling, as well as the slip and erase properties of these beads after the erase after writing will be.

Therefore, the feeling of writing is deteriorated, of course, the sharpness of writing is inferior, and when it is used repeatedly, the eraseability is inferior, and in particular, the durability is weak, so that it cannot be used repeatedly for a long time.

In addition, white boards using board markers cannot use chalk, water chalk, or water-based pens, and they are often used in classrooms or conference rooms. The beam projector screen has a problem in that writing is not possible.

In addition, conventional white boards and blackboards are manufactured in the form of attaching plywood or steel plate on the back to form a large area structurally, or attaching iron plates or magnetic rubber plates on the back to use them as a bulletin board for attaching magnetic objects. Since the weight and volume are large in structure, the portability or mobility is lowered and fixed at a specific position or installed on a cradle.

On the other hand, prior to the present invention, a number of inventions have been pre- filed and registered with respect to writing sheets and films.

In addition, although the Republic of Korea Patent No. 0982224 specifies that the writing sheet having an antimicrobial function and its manufacturing method has a portability using a multi-layered plastic film, it is used as a beam projector screen that is frequently used in lecture rooms or conference rooms There is a problem that can not implement the function for use.

In addition, the Republic of Korea Patent No. 0738517 is a multifunctional plastic sheet and a method of manufacturing the same as the writing and can be used for the beam projector screen, and coated with a UV coating liquid on the acrylate resin coating or the corona-treated first plastic film layer The second plastic film treated with corona treatment is laminated on the first plastic film underneath, and then the lower layer is formed using a (removable) adhesive layer to form a multifunctional plastic sheet for portability, and a UV coating solution is coated on the beam projector. It states that it can be used as a screen.

However, the pre-registered patent is an invention in which a multi-layered plastic film is laminated with an adhesive, and shows a problem in that each plastic film is peeled off during use or the plastic film inside shrinks to form wrinkles.

In addition, the use of a multi-layered plastic film not only increases the cost, but also requires an additional process of laminating, and thus there is a problem in that the manufacturing cost increases in terms of economy.

In addition, the Republic of Korea Patent No. 0422174 relates to a writing board, but the described board forms a printing layer on both sides or one side on a single-layer plastic film, UV coating on the upper or both sides of the printing layer to eliminate the fall of the printing layer. The writing sheet, which is protected and capable of writing, solves the problems caused by using a multi-layered plastic film. However, since the UV coating is applied on the upper part of the printing layer, the peeling or destruction of the printing layer is additionally performed due to the destruction or wear of the UV coating layer. There is a problem in that it can easily occur, the visual beauty falls off, of course, there is no pressure-sensitive adhesive layer to be fixed to the structure as the board itself.

 The conventionally designed writable sheet including the patent uses a special chalk that does not generate chalk powder in order to solve the problem of the chalk powder flying out of the chalk used in the existing blackboard.

 In addition, the eraser needs to be erased in writing with a special chalk, and water or detergent should be sprayed directly on the written place or buried in the eraser.

 In addition, since the cleaning of the dedicated eraser is necessary from time to time, there is a troublesome problem of having to provide a dedicated eraser washing container or cleaning the dedicated eraser from time to time.

In addition, in order to use as a bulletin board for fixing a magnetic object, a work process that requires attaching an additional iron plate or magnetic rubber plate is necessary.

The present invention for solving the above problems is possible to write with various kinds of writing instruments on the market on the surface of the sheet that can facilitate portability, installation, removal, and the like written letters or pictures on the sheet It can be easily erased by dry cloth or papers without the need for water or other cleaning items, and the magnetic surface can be easily attached and detached on the surface of the sheet, and can be used as a beam projector screen if necessary. For the purpose of

The present invention as a means for solving the above problems is a step of forming a printing layer on the back of the plastic film 25-300㎛ thickness and the primer treatment on both sides, and the matting agent 1 to 20 on the upper surface of the plastic film A multi-purpose matt, including forming a matt UV curable coating layer comprising% and a slip agent 0.05-10%, forming a pressure-sensitive adhesive layer on the bottom of the printing layer, and laminating a release layer on the bottom of the pressure-sensitive adhesive layer.

The multipurpose matte pressure-sensitive adhesive sheet 300 of the present invention is a matte UV curable coating layer 110 on the upper surface of one transparent plastic film 100, a print layer 120 printed pictures, characters, patterns, etc. on the bottom, and the printing The bottom surface of the layer 120 has a pressure-sensitive adhesive layer 130 and the release layer 140 is laminated on the bottom of the pressure-sensitive adhesive layer 130.

Therefore, in order to manufacture the multi-purpose matte adhesive sheet 300, first, the printing layer 120 is formed on the back surface of the plastic film 100 having a thickness of 25-300 μm and a primer treatment on both sides thereof (200).

At this time, the plastic film 100 has a thickness of a certain strength to support the configuration of the sheet 300, PE, PVC, PP, PET so that there is no shrinkage or discoloration of the film in the UV curing and heat drying process Preference is given to using.

When the coating layer 110 is coated, it uses a material having excellent adhesion and workability, and these materials may use various materials having the same characteristics.

Therefore, the thickness of the plastic film 100 is preferably used within the range of 25-300㎛ while providing a degree that can be prevented to tear during storage or transport.

If the thickness of the transparent plastic film 100 is less than 25㎛, the plastic film 100 itself may be damaged by heat or other external force received during processing, and if the thickness exceeds 300㎛, the film This is because the processing work is difficult due to its rigidity and weight, and the weight of the finished matte adhesive sheet 100 may be too heavy.

In addition, the plastic film 100 is a weak adhesive force with the coating layer 110 is to use a surface treated normally.

The primer used for surface treatment of the plastic film 110 may be a resin coating such as urethane resin, acrylic resin, and the like, which have been physically treated such as corona and plasma, and the chemical composition of the plastic film 100. Components, surface pretreatment methods and processing methods are not limited.

In addition, the top surface of the plastic film 100 is subjected to the step of forming a matt UV curing coating layer 110 containing a matting agent 1 to 20% and slip agent 0.05 to 10% in 100 parts by weight of the ultraviolet curable coating composition (220). ).

In order to form the matt UV curable coating layer 110 on the upper surface of the transparent plastic film 100, a coating composition which is cured by UV irradiation is applied to the upper surface of the transparent plastic film 100 at a predetermined thickness, and a dryer and an ultraviolet curing machine Through the matt UV curing coating layer 110 is formed.

As used herein, the UV curable coating agent includes a matting agent and a slip agent to implement eraseability and durability in order to realize matte properties and writing and erasing properties.

Therefore, when the content of the quencher is less than 1 part by weight with respect to 100 parts by weight of the ultraviolet curable coating composition, it is difficult to express the matting property, whereas when the content of the quencher is more than 20 parts by weight, the matting property is excellent but the eraseability Not only can it be vulnerable, it can also adversely affect UV curing.

Therefore, when the content of the slip agent is less than 0.05 parts by weight, the eraseability and durability may be weak. On the other hand, when the content of the slip agent exceeds 10 parts by weight, the matting and writing properties are deteriorated. It is preferable to coat with 1 to 20 parts by weight of matting agent and 0.05 to 10 parts by weight of slip agent.

In addition, the step of forming the pressure-sensitive adhesive layer 130 on the bottom of the printed layer 120 (220).

The printing layer 120 formed on the bottom surface of the transparent plastic film 100 is printed in different colors or the same color several times depending on the field where the matte adhesive sheet 300, which is a finished product, is finally applied.

In addition, since the printed layer 120 is located on the bottom surface of the transparent plastic film 100, the printed layer 120 is not removed by the destruction or wear of the matt UV curable coating layer 110.

In addition, the pressure-sensitive adhesive layer 130 formed on the bottom surface of the transparent plastic film 100 on which the matt UV curing coating layer 110 is formed is a permanent adhesive in consideration of the field where the matte pressure-sensitive adhesive sheet 300 is finally applied and the ease of detachment. Alternatively, the removable pressure-sensitive adhesive is uniformly applied to form a drying and curing process.

In addition, a permanent adhesive or a remover is not limited to what is normally used by what is known in the art.

For example, an acrylic adhesive may be used for durability and strong adhesive strength, or an aqueous adhesive may be used for economic efficiency. The foregoing examples are only examples of application, and do not limit the field of application to the present invention.

In addition, the bottom of the pressure-sensitive adhesive layer 130 is completed through the step 230 of laminating the release layer 140.

The release layer 140 laminated on the pressure-sensitive adhesive layer 130 has a matt UV curing coating layer 110, a printing layer 120, and a pressure-sensitive adhesive layer 130 on the transparent plastic film 100 in consideration of packaging, storage, and movement. It is laminated to the included sheet 300, the release layer 140 is a release treatment by paper or film, which is known in the art and does not limit the release treatment method.
