Description

  This invention is formed by placing a sheet of tarpaulin (hereinafter referred to as “tarpaulin sheet”) coated with a synthetic resin film on a knitted fabric or woven fabric manufactured using filament yarn and placing it on a base substrate made of rubber or elastomer. The present invention relates to a method for producing a floor mat for flooring and a wall mat for hanging (hereinafter, the floor mat and wall mat are referred to as “tarpaulin mat”).

  Conventionally, a floor mat and a doormat for a vehicle are mentioned as one body manufactured from a base substrate made of rubber or elastomer and a surface member thereon. However, in these manufacturing methods, the mat body portion is made of natural fiber or synthetic fiber, and a pile made of these fibers is tufted to the base fabric and adhered to the base substrate elastomer that is the flooring material. Some are integrated (for example, see Patent Document 1), and others are disclosed as having a display on a mat (for example, see Patent Document 2). Furthermore, what has a pattern in the mat and protected the pattern with a vinyl chloride sheet (for example, refer to Patent Document 3) is disclosed.

  Moreover, what joined the synthetic resin sheet | seat which is a sheet | seat of rubber | gum or an elastomer, and a vinyl chloride sheet is disclosed what was joined through the adhesive agent (for example, refer patent document 4). Moreover, in the adhesion | attachment of rubber | gum and a resin film, what added the adhesive improvement agent to rubber | gum is disclosed as a method which does not use an adhesive agent (for example, refer patent document 5 and patent document 6).

  Furthermore, a mat printed on a synthetic resin sheet that forms the surface of a tarpaulin sheet is disclosed (see, for example, Patent Document 7 and Patent Document 8).

  By the way, this tarpaulin sheet has a structure in which a knitted fabric or a woven fabric is sandwiched between synthetic resin sheets, and has a structure having flexibility and little expansion and contraction. For this purpose, they are used as banners with characters and designs printed on tents and surfaces, and as advertising media having characters and designs with tension applied thereto. Tarpaulin is also suitable for printing with ink and the like because its surface is made of a resin film, enabling clear printing. However, if it is used in a state where there is no tension, wrinkles and the like are generated, which makes the expression having a display insufficient. Therefore, when used as a rug such as a floor mat, it is necessary to take measures to prevent the ends from being loosened, or to apply tension to the material itself or to apply adhesive force to the back surface to place it on the base. Need to be glued. For this purpose, it is necessary to provide some additional structure to the tarpaulin sheet.

  This tarpaulin sheet is made of a sheet having a structure in which a woven fabric is sandwiched between synthetic resin sheets, and is formed into a structure having flexibility and little expansion and contraction. Therefore, this tarpaulin sheet is used in a tensioned state as an advertising medium having a banner or characters and designs with characters and designs printed on the tent and the surface. Further, since the surface of the tarpaulin sheet is made of a resin film, it is suitable for printing with ink or the like, and clear printing is possible. However, if it is used in a state where there is no tension, wrinkles and the like are generated, which makes the expression medium that is a display medium insufficient. Furthermore, when this tarpaulin sheet is used as a rug such as a floor mat, it is necessary to take measures to prevent the ends from being unwound, or to give tension to the sheet itself or to apply adhesive force to the back surface. It is necessary to adhere to the substrate to be placed. For this reason, it is necessary to provide the tarpaulin sheet with some additional structure.

  On the other hand, a floor mat formed by printing on a conventional tufted pile or non-woven fabric is intended to wipe off dirt on the back of footwear. Therefore, as described above, the floor mat must be washed each time depending on the frequency of use. Furthermore, when it is installed outdoors, it may be discolored due to exposure to rain, etc., so that it is sufficient to maintain the display screen of the display section provided by printing on the surface of the floor mat. It's not a structure. Therefore, in order to prevent such color fading, the color fading is prevented by applying some secondary processing to protect the color fading. However, for this reason, the floor mat is expensive and the productivity is not good.

  Further, when the floor mat is used as a floor mat having a large area, the floor mat using a nonwoven fabric and the floor mat formed by tufting pile yarn are thick and heavy. For this reason, it takes a lot of time to lay the floor mat, and the laying work is not easy. In addition, floor mats that have tarpaulin sheets with a printed surface printed thereon are protected by a coating layer are difficult to endure due to wear of the coating layer, making them unsuitable for use in places with many people. Yes.

It can be seen that the property is very good with ○. Therefore, in the method of the present invention, polyvinyl chloride 8a is used for the synthetic resin sheet 8 in terms of ease of handling, availability, and strength.

  As schematically shown in FIG. 2, a knitted fabric of a knitted fabric 10 a made of filament yarn 10 or a woven fabric of a woven fabric 10 b is sandwiched by a polyvinyl chloride sheet 8 a which is a thermoplastic synthetic resin sheet 8 to form a tarpaulin sheet 6. To do. A base substrate 4 made of rubber 4b or elastomer 4c is provided on the lower surface of the tarpaulin sheet 6, and a protective sheet 11 which is a transparent polyvinyl chloride sheet 11a is further provided on the upper surface of the tarpaulin sheet 6. Alternatively, as shown in the schematic cross section of (b), the tarpaulin mat 1 is formed. In FIG. 3, the polyvinyl chloride sheet 8 a sandwiching the knitted fabric 10 a or the woven fabric 10 b is omitted from the drawing and shown as a tarpaulin sheet 6. By the way, the surface of the tarpaulin sheet 6 is, for example, white, and the printing surface 9 is made clearer by printing characters 9a and designs on the white of the surface to form the printing surface 9. In FIG. 1, it is assumed that the printing surface 9 is printed with characters 9a. The thermoplastic polyvinyl chloride sheet 8a, which is the white surface of the tarpaulin sheet 6, has good familiarity and adhesion to the water-soluble ink forming the printing surface 9, and is also good for solvent-based inks. Has good familiarity and adhesion. Further, as shown in FIG. 3 (b), the outer diameter of the surface of the base substrate 4 made of rubber 4b or elastomer 4c is larger in diameter than the outer periphery of the tarpaulin sheet 6, and only the thickness of the tarpaulin sheet 6 is present. The tarpaulin sheet 6 is fitted and placed in the recessed portion 4 a of the base substrate 4 inside the inner peripheral end surface 5 a of the outer edge portion 5 of the raised base substrate 4. Further, in the case of having the surface of the polyvinyl chloride sheet 8a which is the upper surface of the tarpaulin sheet 6 or having the printing surface 9 on the surface of the polyvinyl chloride sheet 8a, the outer edge is provided when the outer edge portion 5 is provided on the surface. In order to protect both the portion 5 and the printed surface 9 on the surface, it is covered with a protective sheet 11 made of a transparent polyvinyl chloride sheet 11a. Next, the base substrate 4, the tarpaulin sheet 6 having the polyvinyl chloride sheet 8 a on the surface, and the transparent polyvinyl chloride sheet 11 a are integrated by hot pressing and heat fusion, and (a) and ( The tarpaulin mat 1 shown in b) is used.

  The tarpaulin sheet 6 may be covered with the thermoplastic polyvinyl chloride sheet 8a only on the upper surface of the knitted fabric 10a or the woven fabric 10b, or may be covered by sandwiching both surfaces of the knitted fabric 10a or the woven fabric 10b. In this embodiment, as shown in FIG. 2, a method of sandwiching and covering both surfaces of a knitted fabric 10a or a woven fabric 10b with a polyvinyl chloride sheet 8a is described as an example.

  In this tarpaulin mat 1, as shown in FIG. 4 (a), a transparent polyvinyl chloride sheet 11a is used as the outermost layer on the tarpaulin sheet 6 provided on the base substrate 4 made of rubber 4b or elastomer 4c. By providing the protective sheet 11 as described above, the base material 4, the tarpaulin sheet 6, and the transparent polyvinyl chloride sheet 11a on the tarpaulin sheet 6 are superposed as shown by the arrows, and then these are hot pressed. The tarpaulin mat 1 comprising the tarpaulin sheet 6, the base substrate 4 made of rubber or elastomer, and the protective sheet 11 of the transparent polyvinyl chloride sheet 11a thereon is formed by integral molding.

  On the other hand, as shown in FIG. 5B, when the gap 7 occurs between the tarpaulin mat 1 and the outer peripheral end surface 6a of the tarpaulin sheet 6 that is placed and fitted on the surface of the base substrate 4, The gap 7 may be conspicuous and the appearance of the tarpaulin mat 1 may be deteriorated. Therefore, as shown in FIG. 5 (a), the tarpaulin sheet 6 is fitted on the recessed portion 4a of the base substrate 4 inside the outer edge portion 5 formed around the base substrate 4 made of rubber 4b or elastomer 4c. In order to prevent the poor appearance in which the gap 7 is generated, the combined mounting is performed by border printing with the same color as the base substrate 4 on the tarpaulin sheet 6 to make the poor appearance inconspicuous, or Instead of border printing with the same color, the base substrate 4 made of the outer surface 6a of the tarpaulin sheet 6 and the rubber 4b or elastomer 4c is formed by integrally molding the tarpaulin sheet 6 and the base substrate 4 made of rubber 4b or elastomer 4c. As shown in FIG. 3, the material 4 is in contact with the inner peripheral end surface 5 a of the outer edge portion 5 without forming a gap 7. In this case, integral molding is performed by vulcanizing the rubber 4b or the elastomer 4c and heat-sealing. Further, by providing a protective sheet 11 made of a transparent polyvinyl chloride sheet 11a as the outermost layer on the tarpaulin sheet 6 provided on the base base material 4 made of the rubber 4b or the elastomer 4c, the base base material 4, The raw materials of the tarpaulin sheet 6 sandwiched between the polyvinyl chloride sheets 8a and the transparent polyvinyl chloride sheet 11a which is the outermost protective sheet 11 are stacked and integrally molded by hot pressing. When the base substrate 4 made of the rubber 4b or the elastomer 4c has the outer edge portion 5 by this integral molding, the gap 7 between the inner peripheral end surface 5a of the outer edge portion 5 and the outer peripheral end surface 6a of the tarpaulin sheet 6 or the inner periphery thereof. The tarpaulin mat 1 with an improved appearance is formed by eliminating the occurrence of indentation on the end face 5a by integral heat fusion.

  Based on the results shown in Table 1, NBR, which is a synthetic rubber, is used as the rubber 4b or the elastomer 4c which is the base substrate 4 on which the tarpaulin sheet 6 is fitted and placed. In this case, the rubber hardness of the NBR is 30 to 80 degrees, particularly when the floor mat 2 is a rug, it is preferably set in the range of 30 to 65 degrees, and on the back surface of the base substrate 4, As shown in FIG. 6B, by providing the embossed irregularities 11c, the tarpaulin mat 1 is prevented from slipping and slipping with respect to the floor surface when installed on the floor surface.

  Further, the NBR of the synthetic rubber which is the rubber 4b or the elastomer 4c used for the base substrate 4 is a protective sheet which is a polyvinyl chloride sheet 8a which is the outer surface of the tarpaulin sheet 6 and a transparent polyvinyl chloride sheet 11a which is the uppermost layer. As shown in Table 1, the heat sealing property is good as shown in Table 1. Therefore, the tarpaulin sheet 6 and the transparent polyvinyl chloride sheet 11a are heat-sealed to the NBR as the base substrate 4 without using an adhesive. Can be crimped. As a result, the protective sheet 11 made of the transparent polyvinyl chloride sheet 11 a is formed on the floor mat 2, that is, the tarpaulin mat 1 that is not easily peeled off from the upper surfaces of the tarpaulin sheet 6 and the outer edge portion 5 of the base substrate 4. Thus, by adopting the same polyvinyl chloride sheet as the polyvinyl chloride sheet 8a used for the tarpaulin sheet 6 as the transparent polyvinyl chloride sheet 11a of the protective sheet 11, as a natural result, these are formed by thermal fusion. Can be crimped. Accordingly, in the manufacturing process of the tarpaulin mat 1, it is not necessary to use a processing agent that takes time until the adhesive is fixed, and only heat fusion is performed, so that the workability is improved due to the integration, and the manufacturing cost is increased. Can be reduced.

Furthermore, it prevents the image consisting of the printed characters 9a or designs displayed on the tarpaulin mat 1 from becoming difficult to see due to reflection of light or light source or reflection of water droplets such as rain outdoors, and gives the image a stereoscopic effect.

  The first embodiment is an embodiment of the invention according to claim 1. As a manufacturing method of the tarpaulin mat 1 which is the floor mat 2 or the wall mat 3 such as an entrance mat or a floor mat, the base substrate 4 is formed from NBR, that is, acrylonitrile butadiene rubber. Furthermore, as schematically shown in FIG. 2, the structure of the tarpaulin sheet 6 placed on the base substrate 4 is a knitted fabric 10a or woven fabric 10b made of filament yarn 10 and a synthetic resin sheet 8 sandwiching them. It is formed from the polyvinyl chloride sheet 8a. The surface of the upper side of the sandwiched synthetic resin sheet 8 is formed on the tarpaulin sheet 6 by drawing characters 9a and designs by printing. The tarpaulin sheet 6 has a thickness of 0.3 mm. Further, in order to protect the tarpaulin sheet 6, as shown in FIG. 4 (a), an outermost protective sheet 11 that covers the tarpaulin sheet 6 is formed from a transparent polyvinyl chloride sheet 11a. The base substrate 4 made of rubber 4b on which the tarpaulin sheet 6 is placed is formed from NBR which is synthetic rubber. A lower layer made of these base substrates 4 and an intermediate layer made of tarpaulin sheet 6 formed by sandwiching both surfaces of knitted fabric 10a or woven fabric 10b made of filament yarn 10 shown in FIG. 2 with synthetic resin 8 made of polyvinyl chloride sheet 8a. Then, as shown in FIG. 4A, the upper three layers made of the protective sheet 11 of the transparent polyvinyl chloride sheet 11a are stacked in the direction of the arrow, and the tarpaulin sheet 6 is mounted on the base substrate 4. Then, after covering the tarpaulin sheet 6 with a transparent protective sheet 11, these are integrally formed on the tarpaulin mat 1 by thermal fusion as shown in FIG. When the thickness of the tarpaulin sheet 6 is too thicker than 0.3 mm, the polyvinyl chloride sheet 8a on the lower side of the pile made of the filament yarn 10 that forms the tarpaulin sheet 6 and the base substrate 4 at the time of integral molding by heat fusion. Wrapping of the melt due to heat melting between the rubbers 4b becomes worse, and air enters between the surface of the tarpaulin sheet 6 and the protective sheet 11 thereon, and the tarpaulin mat 1 has a poor appearance. A uniform part is produced.

  The second embodiment is another embodiment of the invention according to claim 1. In the second embodiment, unlike the first embodiment, the base substrate 4 formed of NBR which is a synthetic rubber has an outer edge portion 5 on the outer peripheral portion of the upper surface thereof, and a base inside the outer edge portion 5. The surface of the base material 4 is formed in the recessed part 4a of the base base material 4 which is lower than the surface of the outer edge part 5 by the thickness of 0.3 mm of the tarpaulin sheet 6 placed thereon. Accordingly, the tarpaulin sheet 6 is sized to be fitted and placed in the recessed portion 4a of the base substrate. Since the structure of the tarpaulin sheet 6 is the same as that of the first embodiment, the description thereof is omitted. By the way, a transparent protective sheet 11 for protecting both the tarpaulin sheet 6 fitted and placed in the recessed portion 4a of the base substrate 4 and the surface of the outer edge portion 5 of the base substrate 4 around the tarpaulin sheet 6 is provided. It is formed from the polyvinyl chloride sheet 11a. Next, a polyvinyl chloride sheet is formed on both the lower layer of the base substrate 4 made of the rubber 4b formed from the above-mentioned NBR on which the tarpaulin sheet 6 is fitted and placed, and the knitted fabric 10a or the woven fabric 10b made of the filament yarn 10 shown in FIG. As shown in FIG. 5 (a), three layers of the middle layer of the tarpaulin sheet 6 formed by being sandwiched by 8a and the upper layer of the transparent protective sheet 11 of the polyvinyl chloride sheet 11a are overlapped in the direction of the arrows.
