Description

  The present invention includes (1) indoor floor signs for stores, exhibition halls, station premises, government offices, public facilities, etc., (2) pedestrian walkway signs for construction sites, (3) parking lot guidance and parking block signs, The present invention relates to a floor marking sheet for performing advertisements, guidance display, and the like, and a method for constructing a floor marking sheet.

  As a conventional example of a sheet for floor marking, a graphic sheet having a design such as an advertisement or a guide sign on the front surface is applied to the floor surface (for example, plastic tile, concrete floor) by an adhesive layer provided on the back surface. Some of them are applied directly to the surface of a painted floor.

Such a sheet for floor marking has the following disadvantages.
(1) In order to bring the graphic sheet into close contact with the floor surface, it is necessary to remove wax and dirt on the floor surface during construction. After the graphic sheet is removed, it is necessary to restore the wax dropped during the operation.
(2) If the graphic sheet adhesive is highly adhesive, the graphic sheet can be firmly fixed on the floor surface, but it is difficult to peel off. Doing so may damage the floor or leave the adhesive on the floor and soil the floor.
(3) If the adhesive on the graphic sheet is weakly sticky, it can be easily removed from the floor surface, but it will be relatively easy to remove. However, the edge will be removed due to cleaning and waxing during use or traffic of people and equipment. May come off.
(4) Special construction cleaners and contractors are required for construction and removal, and it takes time.

In order to eliminate these disadvantages, the following floor marking sheet has been proposed. That is, it consists of a rubber base material and a graphic sheet material with a pattern arranged on the rubber base material, and a pattern for preventing slipping is formed on the lower surface of the rubber base material. Is an advertising sheet composed of a base layer on which is drawn and a protective layer provided on the base layer (see, for example, Patent Document 1). Since this advertising sheet is laid on the floor without using an adhesive or the like, construction work and removal work are easy, and the floor is not damaged by the adhesive or the like.
JP-A-2005-234392 (pages 4 to 6, FIGS. 1 to 2)

  However, the advertisement sheet has the following disadvantages. In other words, since vulcanized rubber sheets generally contain a large amount of plasticizers and oils, they adhere to the floor surface of exuded paint floors and plastic tiles (P tiles), and further to graphic sheets. It may become contaminated. In recent years, especially for floor marking sheets, graphic designs with high color and high design using digital printing such as inkjet have begun to be adopted. In order not to impair such high quality designs. Therefore, there is a strong demand for measures to prevent the vulcanized rubber sheet from adversely affecting the graphic sheet.

  Accordingly, an object of the present invention is to provide a floor marking sheet that does not damage the floor surface or graphic sheet to be laid.

  The floor marking sheet according to claim 1, wherein an adhesive layer is provided on a surface opposite to a surface closely contacting the floor surface in a floor marking sheet that is laid on a floor surface to display an advertisement or a guidance display. A vulcanized rubber sheet comprising an ethylene-propylene rubber (EPDM) composition, and a graphic sheet comprising a highly polar organic polymer material having a design such as an advertisement or an induction sign on its front surface, It is characterized by being laminated via an adhesive layer.

  According to the floor marking sheet of the first aspect, it is possible to eliminate adverse effects of the vulcanized rubber sheet on the floor surface and the graphic sheet.

  That is, examples of the material of the floor that is liable to be adversely affected by the plasticizer or oil in the vulcanized rubber sheet (hereinafter also referred to as a plasticizer) include painted floor and P-tile. For paint floors, urethane paints and acrylic paints are usually used. On the other hand, a vinyl chloride resin is generally used as the material of the P tile. Further, as the graphic sheet, a vinyl chloride resin is generally used from the viewpoint of durability. These paint floors, P-tile flooring materials and the graphic sheet are all high-polarity organic polymer materials. Therefore, if a liquid component such as a highly polar plasticizer is present in the vulcanized rubber sheet, the exuded liquid component migrates to cause swelling and induce troubles such as dirt, strength reduction, peeling, and cracking. To do.

  On the other hand, since the EPDM composition is a low-polar organic polymer material, a low-polar oil such as paraffin oil is used as a compounding agent such as a plasticizer. Since the floor material made of a high-polar organic polymer material and the graphic sheet do not swell with respect to the low-polar oil, troubles such as contamination, strength reduction, peeling, and cracking are unlikely to occur. Furthermore, since the EPDM composition has high releasability, the vulcanized rubber sheet is less likely to stick to the floor surface and is easy to peel off.

  On the other hand, since the EPDM composition has poor adhesion to the graphic sheet and the graphic sheet is easily peeled off during use, the adhesive layer for improving the adhesion to the graphic sheet is provided. Therefore, inadvertent peeling of the graphic sheet can be prevented.

  Other low-polar rubber materials such as EPDM include natural rubber, styrene-butadiene rubber, and silicone rubber. However, natural rubber and styrene-butadiene rubber are inferior in heat resistance and weather resistance as compared with ethylene-propylene rubber, so that a large amount of an antioxidant is added to reinforce them. This anti-aging agent may leach out and soil the floor and graphic sheet, and is not suitable for this application. Silicone rubber, on the other hand, is a non-contaminating and excellent material, but it is unsuitable because of its high price and is not price competitive.

  Since the floor marking sheet of the present invention configured as described above is fixed by bringing the vulcanized rubber sheet into close contact with the floor surface without using an adhesive or the like, during construction (when laying) It is not necessary to perform a special cleaning operation such as waxing, and even at the time of removal, the floor surface can be prevented from being damaged due to the presence of an adhesive or the like, and the floor surface can be prevented from being damaged due to peeling such as painting or coating. Moreover, since it can construct even if it is not a specialized contractor, temporary removal in use and correction of a construction place can be performed easily.

  In addition, as a method of forming the design of the graphic sheet, a known printing technique such as analog printing including normal gravure printing and screen printing can be applied in addition to digital printing. Among digital printing, ink-jet printing has various media ranging from water-based media to organic solvent-based media, any of which can be applied. Also, a method of applying cut characters to the graphic sheet can be applied, and known materials according to various forming methods of the design can be adopted. Depending on the type of ink and the material of the graphic sheet, an ink receiving layer may be provided on the surface of the graphic sheet.

  The floor marking sheet is completed by simply placing it on the floor, but it may be partially reinforced using an adhesive tape or the like. Further, the back surface of the vulcanized rubber sheet (the surface in contact with the floor surface) may be provided with unevenness by embossing or the like, thereby producing an effect similar to a suction cup during use and firmly fixing to the floor surface. be able to. In particular, even when the floor surface is wet with water, a decrease in the friction coefficient between the floor surface and the vulcanized rubber sheet can be suppressed, and the floor surface can be made difficult to shift. On the other hand, it is easy to peel off because there are irregularities when removing. Moreover, since the weight per apparent volume (thickness × area) can be reduced by providing the unevenness, the weight can be reduced, and the burden on the operator during construction can be reduced.

  The sheet for floor marking according to claim 2 is characterized in that the vulcanized rubber sheet has a thickness of 1 to 3 mm and a specific gravity of 1.2 to 1.4. According to the floor marking sheet according to the second aspect, the floor marking sheet can be firmly fixed on the floor surface with a thickness that does not prevent a passerby from walking.

  In other words, the floor marking sheet is fixed to the floor surface by the weight and flexibility of the vulcanized rubber sheet, and the thickness is made as thin as possible so as not to hinder the passage of passersby. The optimum conditions that satisfy these conditions are a thickness of 1 to 3 mm and a specific gravity of 1.2 to 1.4 of the vulcanized rubber sheet.

  If the thickness is 1 mm or less, the end portion may be turned up during use. If the thickness is 3 mm or more, a step with the floor surface becomes prominent, and a passerby may stumble at this step. On the other hand, when the specific gravity is less than 1.2, the vulcanized rubber sheet becomes too light to be brought into close contact with the floor surface, and when it exceeds 1.4, no particular problem occurs during use. Since the weight increases, the burden on the operator during construction and removal work increases.

  The floor marking sheet according to claim 3, wherein the ethylene-propylene rubber composition is blended with 50 to 100 parts by weight of a filler and 20 to 50 parts by weight of a plasticizer with respect to 100 parts by weight of the ethylene-propylene rubber. It is characterized by doing.

  According to the floor marking sheet according to claim 3, the weight and flexibility that can be firmly fixed on the floor surface without impairing the workability and soiling the floor surface are provided. A vulcanized rubber sheet can be obtained. That is, when the total amount of the filler is less than 50 parts by weight, the vulcanized rubber sheet becomes too soft and lacks workability, and when it exceeds 200 parts by weight, the vulcanized rubber sheet becomes hard and is applied to the floor surface. It becomes difficult to adhere. Furthermore, when the said filler is less than 50 weight part or exceeds 200 weight part, it is difficult to implement | achieve desired specific gravity using the filler which can be normally used.

  On the other hand, when the plasticizer is less than 20 parts by weight, the vulcanized rubber sheet becomes hard and hardly adheres to the floor surface, and when it exceeds 50 parts by weight, depending on the type of plasticizer, the temperature may change rapidly. The vulcanized rubber sheet may bleed (exude).

  As said filler, what is used for the mixing | blending of normal rubber | gum can be used. Among them, various carbon blacks, heavy calcium carbonate, and talc are able to achieve the specific gravity as the vulcanized rubber sheet, and the flexibility of the vulcanized rubber sheet is not impaired even if the amount of the filler added is increased. This is particularly preferable from the viewpoint of cost performance. As the plasticizer, those usually used as a plasticizer for EPDM can be used. Paraffin oil is particularly preferable. In addition, a plurality of types of the filler and the plasticizer may be used in combination.

  The floor marking sheet according to claim 4 is characterized in that an adhesive containing a chloroprene rubber (CR) composition is used for the adhesive layer of the vulcanized rubber sheet. According to the floor marking sheet of claim 4, since the CR composition has good adhesion to the EPDM composition constituting the vulcanized rubber sheet, the graphic sheet is used as the vulcanized rubber sheet. It can be firmly fixed on.

  The graphic sheet is generally made of vinyl chloride resin, but a film of a resin composition other than vinyl chloride resin such as polypropylene or polyethylene terephthalate, paper, synthetic paper, or the like is also used. Here, when the graphic sheet is paper or synthetic paper, the plasticizer of the vulcanized rubber sheet may ooze out and permeate depending on use conditions. However, by forming the adhesive layer using an adhesive containing the CR composition having a high polarity, the graphic sheet further prevents migration of a low-polarity plasticizer or the like in the vulcanized rubber sheet. Can be prevented from being soiled or altered.

  Moreover, since the CR composition exhibits good adhesion to most adhesives, there is a risk of peeling off during use, whatever the adhesive layer described below provided on the graphic sheet. Absent.

  The floor marking sheet according to claim 5 is characterized in that an adhesive layer is provided on the back surface of the graphic sheet. According to the floor marking sheet of claim 5, it is possible to further prevent the migration of a low-polarity plasticizer or the like in the vulcanized rubber sheet, and the graphic sheet is used as the vulcanized rubber. The vulcanized rubber sheet can be reused by separating from the sheet and replacing it.

  Further, since the graphic sheet can be attached to and detached from the vulcanized rubber sheet, the vulcanized rubber sheet and the graphic sheet can be individually brought into the work site. For example, when the design of the graphic sheet is based on digital printing, it is also possible to bring a printing machine to the site and construct it while printing the design on the graphic sheet at the site. As a result, construction can be performed while fine-tuning the design according to the situation around the site and the situation of the floor.

  The sheet for floor marking according to claim 6 is characterized in that an acrylic adhesive is used for the adhesive layer of the graphic sheet. According to the floor marking sheet of claim 6, since the acrylic pressure-sensitive adhesive has a high polarity, the low-polarity plasticizer contained in the vulcanized rubber sheet is further transferred to the graphic sheet. It is possible to prevent the influence on the graphic sheet. The acrylic pressure-sensitive adhesive exhibits good adhesion to the vulcanized rubber sheet.

  The floor marking sheet according to claim 7 is characterized in that a protective layer is laminated on the front surface of the graphic sheet. According to the floor marking sheet of the seventh aspect, the design of the graphic sheet can be protected from dirt and scratches, and the durability of the graphic sheet itself can be improved. As the protective layer, a known transparent film called a laminate film can be used. Among these, vinyl chloride resin is preferable from the viewpoint of scratch resistance and transparency. By providing irregularities on the surface of such a protective layer, it is possible to suppress a decrease in the coefficient of friction when wetted with water, and to prevent a fall accident due to a slip of a passerby.

  The floor marking sheet according to claim 8 is characterized in that the design of the graphic sheet is formed by digital printing. According to the floor marking sheet of the eighth aspect, it is possible to easily and inexpensively cope with a small quantity and a wide variety of designs. In addition, since the design can be printed by bringing a printing machine such as an ink jet printer to the site, the design can be applied while finely adjusting the design according to the situation around the site and the situation of the floor.

  The floor marking sheet construction method according to claim 9 includes an adhesive layer provided on one side of the vulcanized rubber sheet, and a graphic sheet having a design such as an advertisement or a guidance sign on the front side. By laminating the pressure-sensitive adhesive layer provided on the back surface, the vulcanized rubber sheet and the graphic sheet are laminated, and the surface of the vulcanized rubber sheet on which the adhesive layer is not provided and the floor surface It is characterized by laying on the floor surface in such a way as to contact.

  According to the construction method of the floor marking sheet according to the ninth aspect, since it is fixed on the floor surface without using an adhesive or the like, the construction can be easily carried out without having a specialized technique. Further, since the vulcanized rubber sheet and the graphic sheet are separable, the graphic sheet can be exchanged even after being laid on the floor surface.

The floor marking sheet of the present invention has the following effects.
(1) The floor and graphic sheets are not adversely affected by the vulcanized rubber sheet, and clear and easy-to-see advertising and guidance display can be performed. Moreover, since the floor surface can be completely returned to the original state after the use period is over, it can be used with confidence.
(2) Since there is no displacement with respect to the floor surface, and there is no rise during use, guidance display and advertisement can be performed without hindering the passage of passersby.
(3) Due to the cushioning property of the vulcanized rubber sheet, attention can be drawn without obstructing the passage of passersby.
(4) It corresponds to various design formation methods and can be applied to a wide range of uses.
(5) Since the graphic sheet can be easily attached to the vulcanized rubber sheet, it is possible to easily cope with floor markings that are replaced in a relatively short period of several days to several months.
(6) Since the vulcanized rubber sheet can be reused, cost reduction and environmental protection can be achieved.
(7) Since construction only removes and removes dust and dirt from the floor surface, a specialized cleaning company and construction company are not required, and it is possible to reduce the number of workers required for construction and shorten construction time. it can. Thereby, construction cost can be held down.
(8) During removal, since it can be easily peeled off from the floor surface, work using special materials by a specialized cleaner or contractor becomes unnecessary, and the removal work time can be shortened. Thereby, the cost required for removal can be suppressed.
(9) When cleaning the floor surface using a polisher, etc., it is only necessary to move it temporarily from the floor surface and place it again in the original place after cleaning. .
(10) The market will expand as floor marking can be performed easily.

  An embodiment of a floor marking sheet 1 according to the present invention will be described with reference to FIG.

  Fig.1 (a) is the side view which showed typically Example 1 of the sheet | seat for floor markings, and the code | symbol F of the figure has shown the flooring. The floor marking sheet 1 includes a vulcanized rubber sheet 2 that is in close contact with the floor surface Fa and is fixed to the floor surface Fa, and a graphic sheet 3 that has a design such as an advertisement or a guidance sign on the front surface 3a. And a laminate film 4 for protecting the front surface 3a of the graphic sheet 3 (corresponding to the protective layer of claim 7).

  The vulcanized rubber sheet 2 contains 50 to 100 parts by weight of a filler and 20 to 50 parts by weight of a plasticizer with respect to 100 parts by weight of ethylene-propylene rubber (EPDM), and the specific gravity is 1.2 to 1.4. The EPDM composition dough thus prepared was continuously vulcanized with a rotary press to form a sheet having a thickness of 1 mm to 3 mm. An adhesive layer 5 is provided by applying an adhesive containing a chloroprene rubber (CR) composition to the surface 2a opposite to the surface 2b in close contact with the floor surface Fa. As such a vulcanized rubber sheet 2, for example, Bando Sheet CDE (trade name) manufactured by Bando Chemical Co., Ltd. is suitable.

  The graphic sheet 3 is formed of a vinyl chloride resin having excellent durability and weather resistance, and a design such as an advertisement or a guide sign is printed on the front surface 3a by digital printing using an inkjet printer.

  The laminate film 4 is made of a vinyl chloride resin from the viewpoint of scratch resistance, transparency, and the like. The front surface 4a is provided with non-slip irregularities by embossing. The laminate film 4 is attached to the front surface 3a of the graphic sheet 3 with an adhesive or the like, and protects the design printed on the graphic sheet 4 from dirt, scratches, and fading.

  The floor marking sheet 1 configured as described above is an EPDM in which the vulcanized rubber sheet 2 is a low-polar organic polymer material, and thus a paint floor in which a paint of a high-polar organic polymer material is used. Low-polar oil such as a plasticizer contained in the vulcanized rubber sheet is less likely to adversely affect the plastic tile (P tile) and graphic sheet 3 made of the same material. Therefore, troubles such as a decrease in strength, peeling, and cracking of the floor surface Fa and the graphic sheet 3 can be avoided. Further, since the adhesive layer 5 is made of an adhesive containing a high-polarity CR rubber composition, the transition to the graphic sheet 3 such as a low-polarity plasticizer in the vulcanized rubber sheet 2 is prevented, and the graphic sheet 3 Can be prevented from getting dirty or altered.

  Since the vulcanized rubber sheet 2 has a thickness of 1 mm to 3 mm and a specific gravity of 1.2 to 1.4, the vulcanized rubber sheet 2 is in close contact with the floor surface due to its weight and flexibility, and a passerby on the floor marking sheet 1 There will be no slippage even if you pass through. In addition, since the construction is only placed on the floor from which dust and dirt have been removed, no special skills are required, and when removing or moving, the work can be completed simply by peeling off the floor, so anyone can handle it easily. Can do.

  Since the laminate film 4 attached to the graphic sheet 3 has excellent scratch resistance and transparency, the visibility of the design printed on the graphic sheet 3 is maintained for a long period of time, and it is difficult to fade. ing. Further, since the surface 4a is provided with unevenness (not shown) by embossing, it is excellent in slip resistance, and it is difficult to slip on the floor marking sheet even in rainy weather and has safety.

  Next, Example 2 of the floor marking sheet will be described with reference to FIG. FIG. 1B is a side view schematically showing the floor marking sheet 1 ′ of the second embodiment. In addition, about the code | symbol, about the same or equivalent thing as the floor marking sheet 1 of Example 1, it represents using the same code | symbol.

  The floor marking sheet 1 ′ of Example 2 is different from the floor marking sheet 1 of Example 1 in that an acrylic adhesive is applied to the back surface 3 b ′ of the graphic sheet 3 ′ and an adhesive layer 6 is provided. Is different. That is, the graphic sheet 3 ′ is laminated on the vulcanized rubber sheet 2 so that the pressure-sensitive adhesive layer 6 is in contact with the adhesive layer 5 of the vulcanized rubber sheet 2. Since the CR composition used in the adhesive layer 5 of the vulcanized rubber sheet 2 exhibits good adhesion to most adhesives, the graphic sheet 3 ′ may be inadvertently peeled off during use. Absent.

  As the graphic sheet 3 ′ having such an adhesive layer 6, for example, Grand Messe MYC (trade name) of solvent ink inkjet media manufactured by Bando Chemical Co., Ltd. is suitable. Also, instead of the graphic sheet 3 'made of vinyl chloride, Grand Messe PSP (commercial product) of water-based ink jet media made of synthetic paper can be used. Even when this synthetic paper graphic sheet is used, the adhesive layer 5 made of an adhesive containing a highly polar CR composition prevents the migration of a low-polarity plasticizer or the like in the vulcanized rubber sheet 2. Therefore, it is possible to prevent the synthetic paper graphic sheet from being stained or altered.

  According to the floor marking sheet 1 ′ of Example 2, a high-polarity acrylic pressure-sensitive adhesive is used for the pressure-sensitive adhesive layer 6 of the graphic sheet 3 ′, and the low-polarity plastic oozed from the vulcanized rubber sheet 2. The transition of the agent or the like to the graphic sheet 3 is further prevented, and there is no possibility that the graphic sheet 3 becomes dirty or damaged. Further, since the graphic sheet 3 ′ can be easily attached to and detached from the vulcanized rubber sheet 2, the vulcanized rubber sheet 2 can be reused by replacing only the graphic sheet 3 ′, thereby eliminating waste. it can.

Next, a method of laying the floor marking sheet 1 ′ according to the second embodiment will be described with reference to the flowchart of FIG.
On the graphic sheet 3 ′, a design such as an advertisement or a guide sign is digitally printed in advance on the front surface 3a ′ using an inkjet printer (procedure 1).

  In this procedure 1, a separator for protecting the adhesive layer 6 is attached to the back surface 3b 'of the graphic sheet 3'. The formation of the design is not limited to digital printing but may be performed by analog printing such as gravure printing or screen printing, and the design can be formed by a method of pasting cut characters, but if digital printing by an inkjet printer, It can be constructed with fine-tuning the design according to the conditions around the site and the floor.

  Next, the laminate film 4 is adhered to the front surface 3a 'of the graphic sheet 3' (procedure 2). In this procedure 2, a pressure-sensitive adhesive is applied to the back surface of the laminate film 4 in advance, and a separator for protecting the pressure-sensitive adhesive is pasted. The sticking to the graphic sheet 3 is performed after removing the separator. Then, the vulcanized rubber sheet 2 and the graphic sheet 3 'are aligned (procedure 3). Thereafter, the separator for protecting the adhesive layer 5 attached to the vulcanized rubber sheet 2 and the separator of the graphic sheet 3 are peeled off, and the two are attached and laminated in order from the end (procedure 4). The floor marking sheet 1 in which the vulcanized rubber sheet 2, the graphic sheet 3 ′ and the laminate film 4 are integrated is laid at a predetermined position on the floor surface from which dust or dust has been removed in advance (step 5). ).

  When moving or removing, the floor marking sheet is peeled off from the floor surface, and when moving, the work is completed simply by placing it elsewhere. Also, when replacing the graphic sheet, peel off the adhesive layer of the vulcanized rubber sheet and the adhesive layer of the graphic sheet, separate the vulcanized rubber sheet and graphic sheet, and separate another graphic sheet. If both the pressure-sensitive adhesive layer and the adhesive layer of the vulcanized rubber sheet are laminated together, the operation is completed.

(A) is the side view which showed typically Example 1 of the sheet | seat for floor markings which concerns on this invention, (b) is the side view which showed Example 2 typically. It is a flowchart which shows the construction method of the sheet | seat for floor markings concerning this invention.
