Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a desk mat, and more particularly, to a desk mat that is mainly laid on a desk and is made of polyvinyl chloride resin.

[0002]

[Prior Art]

 Desk mats based on polyvinyl chloride resin have been used for a long time, and they have the value of being able to provide cushioning, writing, and texture on the desk. However, conventional desk mats have surface values. Was not subjected to any special treatment.

[0003]

[Problems to be solved by the device]

 That is, since the conventional desk mat is not subjected to any surface treatment as described above, the plasticizer bleeds out (leaches out) on the surface, and stains such as pencils and carbon are easily attached to the surface, and Once it adheres, it has a problem that it is hard to remove the dirt, or the dirt on the surface becomes very noticeable as the number of days of use increases, and it is often bothersome when using a ruler or the like. Was felt.

[0004] Further, when there is no memo paper nearby when it is desired to take a memo of a sudden touch, there are many demands from the user that it is convenient if the memo can be directly written on the surface of the desk mat, but as described above, the stain is not generated. Since it was hard to fall down, I was not able to meet the demand at all.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a desired surface for a desk mat containing a polyvinyl chloride resin as a main component. It is intended to prevent the surface from being stained by improving the stickiness of the surface, and to enable writing and erasing on the mat surface with a marker for whiteboard.

[0006]

[Means for Solving the Problems]

 To achieve the above object, the technical means of the present invention comprises a main body layer formed mainly of polyvinyl chloride resin, and an ultraviolet curable paint coated on the surface of the main body layer. The surface layer is

[0007]

[Action]

 By the technical means described above, the surface is made tough by the ultraviolet curable coating material forming the surface layer, and the surface layer suppresses the leaching of the plasticizer contained in the main body layer to the surface of the desk mat.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The desk mat of the present invention is formed into a flat rectangular shape which is well known in the technical field of this type. The main layer 1 is formed into a sheet or film having a desired thickness by calendering or extruding as the main component, and the surface 1a side of the main layer 1 is coated with an ultraviolet curable paint to form a surface. Layer 2 is provided.

The main body layer 1 is formed of a polyvinyl chloride resin as a main component, a desired additive such as a plasticizer and a stabilizer is added thereto, and the film is formed by a well-known sheet processing method or the like.

The above-mentioned plasticizer is a plasticizer that has been generally used in the past, and the addition amount thereof is about 30 to 60 parts by weight, but it varies up and down depending on the components of the plasticizer.

The main body layer 1 contains a salicylic acid ester-based, benzophenone-based, benzotriazole-based, benzoate-based, cyanoacrylate-based ultraviolet absorber or the like as a plasticizer amount for preventing discoloration of the color copy paper by ultraviolet irradiation, and the main body layer. It may be added according to various conditions such as thickness.

Next, the surface layer 2 will be described. The surface layer 2 is made of an ultraviolet curable coating material containing polyester acrylate, polyurethane acrylate, epoxy acrylate as a main component, and the surface 1a of the main body layer 1 is provided with an ultraviolet lamp. It is obtained by coating so as to have a thickness of about 5 to 30 μm after irradiation.

Before coating the surface layer 2 on the main body layer 1, a desired anchoring agent may be provided on the surface 1a of the main body layer 1.

Explaining a concrete embodiment, the following composition is used to form the main body layer 1 by a T-die with a film thickness of 2 m / m. Polyvinyl chloride resin 100 parts by weight DOP (including epoxidized soybean oil) 50 〃 Ba-Zn stabilizer 2 〃

Next, a surface layer 2 is obtained by coating the surface 1a of the main body layer 1 with a polyurethane acrylate-based UV-curable coating so as to have a thickness of 5 μm after irradiation with an UV lamp.

Although the desk mat of the present invention has been described in detail above, it is merely an example, and the present invention is not limited to this. Also, although not shown, the same applies to the back surface 1b side of the main body layer 1. The above paint may be applied, and by doing so, the transfer of the plasticizer to the copy paper or the like laid under the desk mat can be prevented.

It should be noted that the main body layer 1 and the surface layer 2 may be printed with a calendar, a memo table, a kid's practice book for schoolchildren, a coloring book for children, graffiti, etc., or the above printed matter between the table surface. It is optional to use in a narrow space.

[0018]

[Effect of the device]

 Since the present invention comprises a main body layer formed of a polyvinyl chloride resin as a main component and a surface layer made of an ultraviolet-curable coating film coated on the surface of the main body layer, the surface layer is The constituent UV curable paint makes the surface less tough and harder to stick to. In addition, the plasticizer contained in the PVC body layer does not bleed out to the mat surface, so that dirt and stains on the surface are suppressed. In addition, even if it adheres, it can be easily removed by simply wiping it with a dry cloth or a wet cloth.Since stickiness is reduced and slipperiness is improved, the trouble of using a ruler is eliminated and it is very useful. . Therefore, even if it is used for a long period of time, the original appearance of the desk mat made of vinyl chloride can be maintained, and the aesthetic appearance of the desk mat can be maintained, which is extremely useful and eventually has high commercial value.

Further, according to the present invention, as described above, dirt or the like can be easily removed by lightly wiping it with a dry cloth or a wet cloth. Even if there is it, it will be very convenient because it will be possible to write notes directly on the desk mat, and it will be possible to fully meet the needs of consumers.
