Description

  The present invention relates to a film for disguise used mainly when manufacturing a clay model of an automobile or the like, a clay model manufactured using the film, and a method for manufacturing the clay model.

  When developing industrial products such as automobiles and motorcycles, full-scale or miniature-sized models (models) are manufactured based on the sketches of designers. As a material for manufacturing such a model, industrial clay (hereinafter also simply referred to as “clay”) that can be easily shaped and shaped, such as embedding and shaving, is mainly used. In general, the surface of the clay model body manufactured using clay is colored to complete the clay model. In general, the clay model body can be colored (imitation) by sticking the film for disguise colored in various colors to the surface of the clay model body.

  As a film for disguise used for such a purpose, for example, an adhesive layer made of a water-soluble paste such as starch and a water absorbent paper are sequentially laminated on one side of a colored thermoplastic film. A known clay modeling film is known (Non-patent Document 1). In order to use this clay modeling film, first, the entire film is immersed in water to wet the pressure-sensitive adhesive layer. Next, the water-absorbent paper is peeled off and attached to the surface of the clay model body.

  Further, a non-immersed clay modeling film is known in which a pressure-sensitive adhesive layer made of a pressure-sensitive adhesive and a separator are sequentially laminated on one surface of a colored thermoplastic film (Non-Patent Document 2). . In order to use this clay modeling film, first, the separator is peeled off without being immersed in water. Next, the exposed pressure-sensitive adhesive layer is attached to the surface of the clay model body.

  In addition, as a general marking film stuck on a vehicle interior / exterior material, for example, a (meth) acrylic film, a colorant received on the front side of the film, and a rear side of the film are arranged.

  However, since the clay modeling film disclosed in Non-Patent Document 1 needs to secure a large amount of water and immerse the entire film in water, it takes time and effort during use. Moreover, since it is necessary to discard the waste water from which the water-soluble paste has been eluted, it is necessary to sufficiently consider the influence on the environment. Furthermore, there is a problem in that the eluted water-soluble paste is likely to adhere to the film surface and easily cause dirt.

  Further, the clay modeling film disclosed in Non-Patent Document 2 is likely to generate static electricity when the separator is peeled off from the pressure-sensitive adhesive layer. For this reason, the films are likely to stick to each other due to the influence of the generated static electricity, and workability is likely to deteriorate. Furthermore, there is a problem that the film itself is lost when an attempt is made to peel off the stuck film. In addition, in patent document 1, workability | operativity, a characteristic, etc. which are requested | required of the film for camouflage used in order to manufacture a clay model are not examined at all.

  The present invention has been made in view of such problems of the prior art, and the object of the present invention is excellent in stickability and fixing degree to the clay model body, and excellent in workability. And to provide a highly versatile film for disguise. Moreover, the place made into the subject of this invention is providing the clay model using this film for camouflage, and its manufacturing method.

  As a result of intensive studies to solve the above problems, the present inventors blended a tackifier with the main constituent material (thermoplastic resin) of a colored film without providing a pressure-sensitive adhesive layer formed of a pressure-sensitive adhesive, and colored It has been found that the above problem can be solved by making the film itself a laminated body laminated with a transparent film as a self-adhesive film, and the present invention has been completed.

It is sectional drawing which shows typically one Embodiment of the film for camouflage of this invention. It is a perspective view which shows typically one Embodiment of the film for camouflage of this invention. It is a schematic diagram which shows an example of a structure of a converting machine.

  Embodiments of the present invention will be described below, but the present invention is not limited to the following embodiments. The disguise film of the present invention is a film used for producing a clay model by sticking to the surface of the clay model body. The transparent film made of the first thermoplastic resin and one surface of the transparent film And a self-adhesive colored film made of a second thermoplastic resin, which is disposed in a stacked manner.

<Film for disguise>
FIG. 1 is a cross-sectional view schematically showing one embodiment of a film for disguise according to the present invention. FIG. 2 is a perspective view schematically showing one embodiment of the film for disguise of the present invention. As shown in FIGS. 1 and 2, the disguise film 10 according to this embodiment includes a transparent film 1 and a colored film 2 that is laminated on one surface of the transparent film 1. The transparent film 1 is mainly composed of a first thermoplastic resin. The colored film 2 is a self-adhesive film mainly composed of the second thermoplastic resin and contains a tackifier. And the shearing adhesive force of the colored film 2 is 7.0-30.0N / 25mm, and an initial stage tack is 2 or less. In addition, as shown in FIGS. 1 and 2, the disguise film 10 according to the present embodiment is peeled and laminated on the other surface of the transparent film 1 (a surface different from the surface on which the colored film 2 is disposed). A film 5 may be further provided.

  As described above, the disguise film of the present invention is obtained by blending a tackifier with the second thermoplastic resin, which is the main component of the colored film, without providing a pressure-sensitive adhesive layer formed of the pressure-sensitive adhesive. Is a laminated film using a self-adhesive film. That is, the disguise film of the present invention does not substantially have an adhesive layer made of an adhesive, and the colored film itself constituting the laminated film exhibits self-adhesiveness. For this reason, it does not stick to the extent that the surface of the colored film (sticking surface 15 (see FIG. 1)) is brought into contact with the clay model body, and fine adjustment for determining the sticking position is easy. In addition, after deciding the attachment position, the self-adhesiveness of the colored film is exhibited by applying heat of human skin (for example, palm heat) to the part to be fixed for several seconds to several tens of seconds. A film for camouflage can be fixed to the surface.

  When sticking the film for disguise of the present invention to the surface of the clay model body, it is not necessary to immerse in water unlike the film disclosed in Non-Patent Document 1, and therefore the operation is simple. Furthermore, since the waste water from which the aqueous paste is eluted does not occur, it is possible to reduce time and effort for discarding the waste water, and there is no burden on the environment. Moreover, since the colored film which comprises the film for camouflage of this invention is a self-adhesive film, a separator is stuck on the sticking surface (surface of an adhesive layer) like the film disclosed by the nonpatent literature 2. There is no need to keep it on. Therefore, static electricity hardly occurs at the time of sticking, and the workability is excellent. Further, even when the colored films are in contact with each other, they can be peeled off very easily, so that problems such as film loss do not occur. Therefore, the disguise film of the present invention is a highly versatile film that can be easily handled even by a person other than a so-called expert.

(Transparent film)
The transparent film constituting the camouflage film of the present invention is composed mainly of the first thermoplastic resin. Specific examples of the first thermoplastic resin include polyvinyl chloride, polyolefin, polyester resin, acrylic resin, acetate resin, and ethylene / vinyl acetate copolymer. These thermoplastic resins can be used individually by 1 type or in combination of 2 or more types.

  The transparent film (resin composition comprising the first thermoplastic resin that constitutes the transparent film) has a coloring component (color) such as a clear organic pigment or an inorganic pigment, if necessary, as long as the transparency is not impaired. Material) may be included. By containing a coloring component in the transparent film, the color tone of the adjacent colored film can be changed. If an example is given, while making a colored film contain an aluminum filler and making it a silver metallic color tone, the whole color tone can be made golden by making a transparent film contain a clear yellow or orange color material. In addition, you may make the transparent film contain various additives, such as a plasticizer, a ultraviolet absorber, a light stabilizer, and an antistatic agent, as needed.

  As the plasticizer, for example, a polyester plasticizer or an aromatic plasticizer can be used. In particular, it is preferable to use a polyester plasticizer and an aromatic plasticizer in combination. By using a polyester plasticizer and an aromatic plasticizer in combination, it is possible to further improve the degree of fixation of the disguise film on the clay model body and to further enhance the texture of the transparent film surface.

  The thickness of the transparent film is not particularly limited, and can be appropriately determined in consideration of handleability, practical strength, designability, and the like. The thickness of the transparent film is usually 10 to 100 μm, preferably 20 to 70 μm. If the transparent film is too thick, the degree of fixation to the clay model body and the texture of the film surface may be reduced. On the other hand, if the transparent film is too thin, the film surface texture, hue and brightness may be lowered.

(Colored film)
The colored film constituting the camouflage film of the present invention is mainly composed of the second thermoplastic resin. Specific examples of the second thermoplastic resin include the same examples as the specific example of the first thermoplastic resin. Note that the first thermoplastic resin and the second thermoplastic resin may be the same type or different types.

  As described above, the colored film is not a pressure-sensitive adhesive layer formed of a so-called pressure-sensitive adhesive, but is a self-adhesive film formed mainly of the second thermoplastic resin. Therefore, the shear adhesive strength of the colored film is 7.0 to 30.0 N / 25 mm, and preferably 10.0 to 20.0 N / 25 mm. When the shearing adhesive strength of the colored film is less than 7.0 N / 25 mm, the adhesive strength is too low, and the degree of fixing to the clay model body is insufficient. On the other hand, when the shearing adhesive strength of the colored film is more than 30.0 N / 25 mm, the adhesive strength is too strong, making it difficult to change or reattach the fixing portion and to easily adhere the colored films to each other. Is lacking. Moreover, the initial tack of the colored film (ball tack in the previous stage of sticking to the clay model body) is 2 or less. When the initial tack of the colored film is more than 2, workability and handleability are reduced as in the case where the shear adhesive strength is too strong. Furthermore, when reattaching, a part of the clay model main body may adhere to the surface of the colored film, and the attaching operation itself may have to be interrupted. In the present specification, “shear adhesive strength of colored film” means shear adhesive strength (unit: N / 25 mm) measured according to JIS Z 0237: 2009 (adhesive tape / adhesive sheet test method). To do. Further, in this specification, “initial tack of colored film” refers to J. JIS Z 0237: 2009 (adhesive tape / adhesive sheet test method) based on JIS Z 0237: 2009. It means a ball tack (unit: ball number) measured by the DOW method under the condition of an inclination angle of 30 °.

  The colored film contains a tackifier. Thereby, a colored film shows self-adhesiveness. In addition, the adhesive force of a colored film can be made into said predetermined range by setting content of a tackifier suitably.

  As a tackifier, the usual tackifier which can be used when forming a self-adhesive film can be used. Specific examples of tackifiers include phenolic tackifiers, terpene tackifiers, rosin tackifiers, xylene resins, aliphatic hydrocarbon resins, aliphatic / aromatic copolymer resins, aliphatic / alicyclic rings. Group copolymer resin, hydrogenated petroleum resin, C5 petroleum resin, C5 / C9 petroleum resin, and the like. These tackifiers can be used singly or in combination of two or more.

  The content (solid content) of the tackifier in the colored film (resin composition containing the second thermoplastic resin constituting the colored film) is preferably 1 to 60% by mass, and 5 to 30% by mass. % Is more preferable, and 10 to 25% by mass is particularly preferable. When the content of the tackifier is less than 1% by mass, the colored film may have insufficient adhesive strength (self-adhesiveness). On the other hand, when the content of the tackifier is more than 60% by mass, the adhesive strength of the colored film is excessively increased, the strength may be insufficient, and the cost may be disadvantageous.

  The colored film usually contains a colored component (coloring material). The kind of the coloring component is not particularly limited, and a color material or the like for making the disguise film have a preferable color tone is appropriately selected and used. As the coloring component, for example, an organic pigment or an inorganic pigment can be used. Moreover, you may make a colored film contain various additives, such as a plasticizer, a ultraviolet absorber, a light stabilizer, and an antistatic agent, as needed.

  The thickness of the colored film is not particularly limited, and can be appropriately determined in consideration of handling properties, practical strength, design properties, and the like. The thickness of the colored film is usually 10 to 100 μm, preferably 20 to 70 μm.

(Disguised film)
The thickness of the disguise film of the present invention (the total thickness of the transparent film and the colored film) is preferably 10 to 200 μm, and more preferably 40 to 140 μm. If it is too thick, the degree of fixation to the clay model body may decrease, or the handleability may decrease due to the increase in weight. On the other hand, if it is too thin, the handleability may also deteriorate.

  The tensile strength at break of the disguise film measured according to JIS K 6732: 2006 is preferably 5.0 to 20.0 MPa, and more preferably 7.0 to 15.0 MPa. Moreover, it is preferable that the tensile fracture | rupture elongation of the film for camouflage measured based on JISK6732: 2006 is 50 to 400%, and it is further more preferable that it is 100 to 350%. If the tensile rupture strength and the tensile rupture elongation are within the above ranges, respectively, the disguise film can be stretched by being moderately stretched, and stress can be generated in the colored film without causing glossiness or the like in the transparent film. it can. Further, the entire film is not peeled off or twisted, and can be made to follow the curved surface portion, the complicated shape portion, the uneven portion and the like of the clay model main body, and more excellent adhesion can be exhibited.

(Manufacturing method of disguise film)
Next, the manufacturing method of the film for camouflage of this invention is demonstrated. The method for producing a film for disguise according to the present invention is a method for forming a transparent film using a first thermoplastic resin and a first resin composition containing various additives such as a plasticizer used as necessary. A colored film is formed using the first resin composition and the second resin composition containing the second thermoplastic resin, tackifier, coloring component, and various additives such as a plasticizer used as necessary. A second step.

  The transparent film can be formed by, for example, a casting method. The casting method may be a method using an extruder (extruder) or a solution casting method in which a solution obtained by dissolving a thermoplastic resin or the like in an organic solvent is formed. Furthermore, a transparent film can also be formed by a calendar method.

  For example, by using a converting machine, a transparent film, a colored film, and a fake film in which these are laminated can be manufactured. FIG. 3 is a schematic diagram illustrating an example of a configuration of a converting machine. In order to form a transparent film in the first step, first, the first resin composition is put into the receiving container 20 of the converting machine 100 shown in FIG. Next, after depositing the first resin composition on the process film 25 (or process paper), the process film 25 is moved to the film forming head 30 to form a coating film having a predetermined thickness. . Further, the process film 25 is sequentially fed into and passed through the drying furnace 35 to volatilize the organic solvent. Thereby, only the solid content in the first resin composition remains, and a transparent film having a predetermined thickness can be formed. In addition, the formed transparent film can be wound up continuously after appropriately cooling. What is necessary is just to let the temperature in the drying furnace 35 be the range of 70-130 degreeC, for example. Further, the line speed may be in the range of 1 to 20 m / min, for example.

  As the process film 25, for example, a release film made of a resin such as polyester, polyethylene, or polypropylene, a paper film (release paper), or the like can be used. The process film may be one-side peeled or double-sided peeled. In addition, when the film for process is a thing by which the peeling process was carried out, it is preferable that the peeling force of two surfaces differs (example: heavy peeling and light peeling). When the film for a process from which the peeling force of two surfaces differs is used, reverse sticking of the completed film can be prevented.

  Even when the colored film is formed in the second step, it may be the same as in the first step. That is, in order to form a transparent film in the second step, first, the second resin composition is put into the receiving container 20 of the converting machine 100 shown in FIG. Next, after the second resin composition is attached onto the process film 25 (or process paper), the process film 25 is moved to the film formation head 30 to form a coating film having a predetermined thickness. . Further, the process film 25 is sequentially fed into and passed through the drying furnace 35 to volatilize the organic solvent. Thereby, only the solid content in the second resin composition remains, and a colored film having a predetermined thickness can be formed. The temperature in the drying furnace 35 is preferably 60 to 150 ° C, more preferably 70 to 130 ° C.

Then, using the heated pressure roll 40, while laminating | stacking the formed colored film and the transparent film obtained at the 1st process, it is wound up on heating-pressing conditions, making the process film 25 peel. Thereby, the film for camouflage of this invention which has a laminated structure can be manufactured continuously. The pressure of the pressure roll 40 is preferably in a 1~15kg / cm ^2, and even more preferably from 2 to 10 kg / cm ^2. The temperature of the pressure roll 40 is preferably 60 to 150 ° C, more preferably 90 to 120 ° C.

<Clay model and its manufacturing method>
If the film for camouflage of the present invention described above is used, a clay model of an industrial product such as an automobile or a motorcycle can be easily manufactured as compared with the case where a conventional film is used. That is, the clay model of the present invention includes a clay model main body and the above-described camouflage film in which the surface of the colored film (sticking surface) is disposed on the surface of the clay model main body. Moreover, the manufacturing method of the clay model of this invention has the process of sticking the surface (sticking surface) of the colored film of the above-mentioned camouflage film on the surface of a clay model main body. In addition, the manufacturing method of the clay model of this invention is substantially the same as the manufacturing method of the conventional clay model except using the above-mentioned film for camouflage.
