Description

  TECHNICAL FIELD The present invention relates to an outdoor internally-illuminated membrane material having a phosphorescent fluorescence function (a phosphorescent property and an afterglow property), and a construction using the same. In more detail, it functions as an internally illuminating membrane material for outdoor use at night, and in the event of a sudden power outage, the membrane material itself emits light and can serve as a landmark or signpost for the public without requiring power. The present invention relates to a possible outdoor illuminating membrane material and an internally illuminating construction such as a signboard, awning, or monument in which the outdoor illuminating membrane material is attached to a frame.

  Internally illuminated outdoor signboards are widely used because of their free design and eye-catching properties. Examples of materials used for the signboard include acrylic resin plates and membrane materials (flexible face sheets). Recently, the use of membrane materials is increasing from the viewpoints of ink jet printing suitability, durability, and flame resistance. Such membrane materials for internally illuminated outdoor signboards are often used for signboards such as convenience stores and gas stations.

  Recently, social roles such as convenience stores and gas stations located throughout the country are expected to function as evacuation guidance stations and return home support stations in the event of a disaster. In particular, when a disaster occurs at night and a wide-area power outage occurs, there is a risk of becoming a dark panic and panic without knowing the evacuation passage and evacuation site. Therefore, there is a need for visual recognition means that can evacuate and guide immediate people when such a situation occurs.

Conventionally, as a visual recognition means in such a situation, application of a phosphorescent fluorescent (phosphorescent and afterglow) substance is known. Calcium sulfide (CaS · Bi) and zinc sulfide (ZnS · Cu) phosphors are known as phosphorescent fluorescent (phosphorescent and afterglow) substances. The former has a low afterglow luminance, and the latter has a residual phosphor. There are drawbacks such as short duration of light (afterglow time), and so far there have been almost no cases where it is put to practical use as a phosphorescent phosphor film material.
Recently, as phosphorescent phosphors having afterglow brightness and afterglow time about 10 times that of zinc sulfide phosphors, calcium aluminate, strontium aluminate, and barium aluminate containing ions such as europium and dysprosium as activators. A phosphorescent phosphor is proposed (Patent Document 1: Japanese Patent Laid-Open No. 7-11250), and a vinyl chloride resin composition using the phosphor is also proposed (Patent Document 2: Japanese Patent Laid-Open No. 7-247391). Publication).

  In addition, as a phosphorescent fluorescent sheet that can withstand indoor and outdoor use, a sheet is proposed in which a PVC sheet containing a phosphorescent phosphor is laminated on a substrate layer with a whiteness of 60 or more and various antifouling layers are formed on the surface. (Patent Document 3: JP-A-10-250006). Further, a laminate is proposed in which the skin is a transparent hard PVC film, the intermediate layer is a soft PVC sheet containing a phosphorescent phosphor, and the lower layer is a white hard PVC sheet (Patent Document 4: JP-A-11-138709). Issue gazette). However, when these sheets are used for internally illuminated outdoor signs, the surface color is colored yellow due to the effect of phosphorescent phosphors (phosphorescent pigments). The color development of the wearing part is inferior, and the white layer located under the phosphorescent phosphor layer lowers the light transmittance of the sheet, so that the brightness due to nighttime interior illumination becomes insufficient, and the internally illuminated signboard It was a sheet that did not function at all. Therefore, it is a film material for internally illuminated outdoor signage having a phosphorescent fluorescent function (phosphorescent and afterglow) that can serve as a mark as an evacuation guidance station or a return home support station when a large-scale blackout occurs due to a nighttime disaster, Moreover, there has never been a seat that can be used beautifully as a signboard for a convenience store or a gas station, or as a signboard for a store.

  The present invention normally functions as a conventional outdoor illuminating membrane material, and when a sudden disaster occurs at night and power transmission stops and it becomes dark, it emits light by itself to The present invention is intended to provide an extremely useful outdoor internally-illuminated membrane material that serves as a mark, and an internally illuminated construction material such as a signboard, awning, or monument in which the outdoor internally-illuminated membrane material is attached to a frame.

  In order to solve such a problem, the present inventors have intensively studied, and as a result, a laminated structure in which a semi-concealing resin layer having specific whiteness and specific total light transmittance is provided on a phosphorescent phosphor-containing resin layer. By using the body, it was found that an internally illuminated membrane material for outdoor use satisfying both the whiteness of the surface during normal use and the light-emitting property during a nighttime power outage.

  That is, the outdoor illuminating membrane material of the present invention has a whiteness (JIS Z8722) of 50 to 80 and a total light transmittance (JIS K7105) of 40 to 70% on the phosphorescent phosphor-containing resin layer. It is a laminated structure of at least two layers provided with a concealing resin layer, wherein the semi-concealing resin layer transmits light emitted from the phosphorescent phosphor-containing resin layer. The outdoor internally-illuminated membrane material of the present invention preferably includes a base fabric formed of a fiber material, and the base fabric may be included in the semi-hiding resin layer, and the phosphorescent phosphor-containing resin It may be included under the layer. The semi-concealing resin layer of the outdoor internally-illuminated membrane material of the present invention preferably has an antifouling layer or a printed layer. The outdoor internally-illuminated membrane material of the present invention preferably has a total light transmittance of 10 to 40% as defined in JIS K7105. The construction object of the present invention is a signboard, an awning, or a monument in which the outdoor internally-illuminated film material is attached to the frame with the phosphorescent phosphor-containing resin layer inside and facing the illuminating lamp.

According to the present invention, outdoor color that sufficiently satisfies the color developability under daylight in the daytime and the brightness and color developability due to nighttime illumination, and also has sufficient afterglow luminance (mcd / m ² ). An internally-illuminated membrane material can be provided. In addition, the signboard, awning, or monument, etc., with the outdoor interior-illuminated membrane material attached to the frame, not only satisfies the color development under sunlight during the day and the brightness and color development due to night illumination. However, if a sudden disaster occurs at night and power transmission stops and it becomes dark, it becomes a very useful internally-illuminated construction that emits light and serves as a mark for evacuation passages and evacuation sites.

  In the outdoor illuminating membrane material of the present invention, the semi-concealing resin layer is made of a thermoplastic resin containing a white pigment. The thermoplastic resin constituting the semi-hiding resin layer is not particularly limited, and examples thereof include vinyl chloride resin, vinyl chloride copolymer resin, olefin resin, olefin copolymer resin, urethane resin, urethane copolymer resin, and acrylic resin. Resin, acrylic copolymer resin, vinyl acetate resin, vinyl acetate copolymer resin, styrene resin, styrene copolymer resin, polyester resin, polyester copolymer resin, and thermoplastic resin such as fluorine copolymer resin alone Or by blending two or more. Among these thermoplastic resins, vinyl chloride resins, vinyl chloride copolymer resins, urethane resins, urethane resins are used to obtain ease of processing, flexibility of film materials, adhesion when laminated with a base fabric, etc. A copolymer resin, an acrylic resin, and an acrylic copolymer resin are particularly preferably used. Also, there is no particular limitation on the white pigment contained in the semi-hiding resin layer, and titanium oxide (rutile type, anatase type), zinc white, lithopone (mixture of zinc sulfide and barium sulfate), barium sulfate, calcium carbonate, etc. are used alone. Alternatively, a blend of two or more is preferably used, and titanium oxide having excellent whiteness is particularly preferably used. In addition to this, the semi-concealing resin layer is not limited to the effect of the present invention, but, if necessary, an ultraviolet absorber, an antioxidant, a flameproofing agent, an antifungal agent, a pigment, an antistatic agent, a filler, a stable Other known additives such as an agent and a plasticizer may be included.

  The semi-concealing resin layer preferably has an antifouling layer or a printing layer. The method for imparting the antifouling layer or the printing layer to the semi-concealing resin layer is not particularly limited as long as the effect of the present invention is not impaired. For example, urethane resin, urethane copolymer resin, acrylic resin, and acrylic resin Coating of a resin solution comprising at least one of a copolymer resin and a fluorine-based copolymer resin, coating of a resin solution further containing silica fine particles or colloidal silica, coating agent containing an organosilicate and / or a condensate thereof Coating, coating of a coating agent containing a photocatalytic inorganic material (for example, photocatalytic titanium oxide) and a binder, or urethane resin, urethane copolymer resin, acrylic resin, acrylic copolymer resin, fluorine copolymer resin It can be easily applied by laminating a resin film comprising at least one of the above. Since the semi-concealing resin layer has an antifouling layer, the appearance of the construction can be kept clean, and transmission of light emission at the time of night power outage can be prevented from being obstructed by dirt. Moreover, since the semi-concealing resin layer has a printing layer, decoration with high designability by ink jet printing becomes possible, and the designability of the construction can be further enhanced. The semi-concealing resin layer may have both an antifouling layer and a printed layer.

The whiteness defined by JIS Z8722 of the semi-hiding resin layer is preferably 50-80. When the whiteness of the semi-concealing resin layer is less than 50, the surface color is colored yellow due to the effect of the phosphorescent phosphor (phosphorescent pigment). The color developability is inferior, and the color of transmitted light may become yellowish due to the effect of the phosphorescent phosphor (phosphorescent pigment) during night illumination. When the whiteness of the semi-concealing resin layer exceeds 80, the color developability under sunlight during the day is improved, but the total light transmittance of the semi-concealing resin layer decreases because the amount of white pigment added increases, The light emission of the phosphorescent fluorescent material-containing resin layer may not be sufficiently transmitted.
The total light transmittance (JIS K7105) of the semi-hiding resin layer is 40 to 70%. If the total light transmittance is less than 40%, the light emission (afterglow luminance) of the phosphorescent phosphor-containing resin layer may not be sufficiently transmitted, and if it exceeds 70%, the surface color becomes phosphorescent fluorescence. Since it is colored yellow under the influence of the body (phosphorescent pigment), the color development of the printed part and marking film attachment part is inferior in daylight, and the effect of the phosphorescent phosphor (phosphorescent pigment) during night illumination In some cases, the color of transmitted light becomes yellowish and the color developability is lowered.

In the outdoor illuminating membrane material of the present invention, the phosphorescent phosphor material-containing resin layer is made of a thermoplastic resin containing a phosphorescent phosphor material. Here, the phosphorescent fluorescent material refers to a substance having a performance (afterglow) which is excited by irradiating light and continues to emit fluorescent color after the light irradiation is stopped. The thermoplastic resin constituting the phosphorescent phosphor-containing resin layer is not particularly limited. For example, vinyl chloride resin, vinyl chloride copolymer resin, olefin resin, olefin copolymer resin, urethane resin, urethane copolymer. Thermoplastics such as resin, acrylic resin, acrylic copolymer resin, vinyl acetate resin, vinyl acetate copolymer resin, styrene resin, styrene copolymer resin, polyester resin, polyester copolymer resin, and fluorine copolymer resin The resins can be used alone or in a blend of two or more. Among these thermoplastic resins, vinyl chloride resins, vinyl chloride copolymer resins, urethane resins, urethane resins are used to obtain ease of processing, flexibility of film materials, adhesion when laminated with a base fabric, etc. A copolymer resin, an acrylic resin, and an acrylic copolymer resin are particularly preferably used. In addition, there is no particular limitation on the phosphorescent phosphor contained in the phosphorescent-containing phosphor-containing resin layer. For example, a divalent metal aluminate with a base crystal added with a rare earth element as an activator is used. it can. Divalent metals include magnesium, calcium, strontium, barium, zinc, and rare earth elements include cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, etc. These rare earth elements may be used alone or in combination. Among them, SrAl ₂ O ₄ : Eu, Dy, Sr ₄ Al ₁₄ O ₂₅ : Eu, Dy, CaAl ₂ O ₄ : Eu, Nd, Sr ₄ (Al · B) ₁₄ O ₂₅ : Eu, Dy, etc. are preferable. In particular, an alumina strontium oxide based phosphorescent phosphor having excellent afterglow properties is preferred. The average particle diameter of the phosphorescent phosphor is preferably 1 to 100 μm, more preferably 10 to 50 μm. In consideration of the dispersibility of the phosphorescent phosphor, two or more types having an average particle diameter may be used in combination. The content of the phosphorescent fluorescent material is preferably 20 to 60% by mass. When the phosphorescent phosphor content is less than 20% by mass, the phosphorescent action of the phosphorescent phosphor-containing resin layer becomes insufficient, resulting in a product with low afterglow brightness and short afterglow time. On the other hand, when the content exceeds 60% by mass, the resin strength of the phosphorescent phosphor-containing resin layer is lowered, and the durability as an outdoor illumination film material for outdoors may be insufficient. Similarly, when the content exceeds 60% by mass, the total light transmittance of the phosphorescent phosphor-containing resin layer is lowered, and the translucency necessary for an outdoor illuminating film material may not be obtained. In addition, the phosphorescent action and the light emitting action are not efficiently performed, and the afterglow luminance may be lowered.

  The luminous phosphor-containing resin layer preferably has a total light transmittance of 50% or more as defined in JIS K7105. When the total light transmittance of the phosphorescent fluorescent substance-containing resin layer is 50% or more, the phosphorescent action and the afterglow action are efficiently performed on all the phosphorescent fluorescent substances in the phosphorescent fluorescent vinyl chloride resin layer. And afterglow brightness is improved. On the other hand, when the total light transmittance is less than 50%, the phosphorescent action and the light emitting action are not efficiently performed, and the afterglow luminance may be lowered. The phosphorescent-containing fluorescent substance-containing resin layer of the outdoor internally-illuminated membrane material of the present invention is additionally provided with an ultraviolet absorber, an antioxidant, a flameproofing agent, and an antifungal as necessary as long as the effects of the present invention are not impaired. Agents, pigments, antistatic agents, adhesives, fillers, stabilizers, plasticizers and other additives may be included.

The outdoor internally-illuminated membrane material of the present invention preferably includes a base fabric made of a fiber material in order to increase the strength and durability. The fiber material used is not particularly limited. Natural fibers such as cotton and hemp, inorganic fibers such as glass fibers, carbon fibers and metal fibers, recycled fibers such as viscose rayon and cupra, di- and tri-acetates Appropriately selected from semi-synthetic fibers such as fibers, and polyamide (nylon 6, nylon 66, etc.) fibers, polyester (polyethylene terephthalate, etc.) fibers, aromatic polyamide fibers, acrylic fibers, polyvinyl chloride fibers, polyolefin fibers, etc. can do. The base fabric may be a knitted fabric made of these fiber materials, in which yarns of any shape such as short fiber spun yarn, long fiber yarn, split yarn, tape yarn or the like are knitted. The nonwoven fabric used may be a composite fabric obtained by combining two or more of a knitted fabric, a woven fabric, and a nonwoven fabric, and includes, for example, warps and wefts arranged in parallel with a gap between yarns. A coarse knitted fabric composed of yarn and having a basis weight of 30 to 700 g / m ² and a pore area ratio of about 10 to 95% with respect to the entire surface area, and a basis weight of 50 to 1000 g / m ² , Non-coarse knitted fabrics having a structure such as plain weave, twill weave, circular knitting, weft knitting, and warp knitting (a knitted fabric with substantially no gap formed between yarns) should be used as appropriate according to the purpose of use. Can do.

  The said base fabric may be contained in the semi-concealment resin layer, and may be contained under the luminous fluorescent substance content layer.

  As long as the effect of the present invention is not hindered, the base fabric may be appropriately subjected to pretreatment such as adhesion treatment, water absorption prevention treatment, and flameproofing treatment as necessary using conventionally known materials and methods. it can.

  The base fabric may also be provided with a resin layer made of a thermoplastic resin on one side or both sides thereof as long as the effects of the present invention are not impaired. Agents, antioxidants, flameproofing agents, antifungal agents, pigments, antistatic agents, adhesives, fillers, stabilizers, plasticizers and other additives may be included.

  The outdoor internally-illuminated membrane material of the present invention preferably has a total light transmittance of 10 to 40% as defined in JIS K7105. If the total light transmittance is less than 10%, the brightness when used as an internally-illuminated construction may be insufficient, and light emission at the time of a night power outage may be insufficient. If the total light transmittance exceeds 40%, when used as an internally-illuminated construction, the internal illumination can be seen through, and its usefulness may be impaired.

  According to the construction of the present invention, the outdoor internally illuminated film material is attached to the frame with the phosphorescent phosphor-containing resin layer inside and facing the illuminating lamp, so that the internal illumination light is stored during night illumination. Directly irradiates the resin layer containing fluorescent material, the phosphorescent state is always sufficient, and even if power transmission stops at night and it becomes completely dark, it can emit enough light and can always be a mark for evacuation passages and evacuation sites . Furthermore, as another application example of the construction of the present invention, the power required for illumination can be reduced by using a method of turning on / off the internal illumination such as turning on the internal illumination again after stopping the internal illumination for a certain time during night illumination. You can also expect to save power. In addition, since the color of the phosphorescent phosphor (phosphorescent pigment) does not affect the surface color, it is possible to sufficiently maintain the color developability of the printing part and marking film attaching part during the day.

The invention is further illustrated by the following examples. In the following examples, the test methods used for product performance evaluation are as follows.

[Comparative Example 1]
In the same manner as in Example 1, an outdoor illuminating membrane material was produced. However, as a semi-concealing resin layer, a film (thickness: 0.15 mm) made of a resin composition of the following formulation 5 is formed, and this film is stuck on a phosphorescent fluorescent substance-containing resin layer and used for outdoor illumination. A formula membrane material was obtained.

The obtained outdoor-illuminated membrane material has a low whiteness of the semi-concealing resin layer, so that it has poor color development under sunlight during the day compared to Example 1, and also transmits light by night illumination. The phosphorescent pigment easily affects the color, and the translucent color becomes yellowish, which is insufficient as an outdoor illuminating film material.

[Comparative Example 2]
In the same manner as in Example 1, an outdoor illuminating membrane material was produced. However, as a semi-concealing resin layer, a film (thickness: 0.15 mm) made of a resin composition of the following formulation 6 was formed, and this was stuck on a phosphorescent fluorescent substance-containing resin layer to be used for outdoor illumination.

The obtained outdoor illumination membrane material has a high whiteness of the semi-concealing resin layer as high as 90, good color developability under sunlight during the day, and brightness and color developability due to night illumination. Although fully satisfied, since the total light transmittance of the semi-hiding resin layer is as low as 30%, it becomes difficult to transmit light emitted from the phosphorescent phosphor-containing resin layer, and the afterglow luminance is larger than that in Example 1. In the unlikely event that power transmission stops at night and becomes dark, it is insufficient as a film material that emits light by itself and serves as a mark for evacuation passages and evacuation sites.

2 parts by weight of triazole ultraviolet absorber
Titanium oxide (white pigment) 0.2 parts by mass This internally illuminated membrane material for outdoor use was subjected to the above test. The test results are shown in Table 2.
The resulting laminated structure has a high total light transmittance of the semi-concealing resin layer as high as 80%, while the whiteness is as low as 35, so that the color developability under sunlight during the day is inferior to that in Example 1. In addition, the luminous pigment tends to affect the translucent color due to nighttime internal illumination, and the translucent color becomes yellowish, which is insufficient as an internal illumination film material for outdoor use.

[Comparative Example 4]
In the same manner as in Example 2, an outdoor illuminating membrane material was produced. However, the laminated structure was subjected to the above test with the front and back sides reversed. The test results are shown in Table 2.
Since the phosphorescent-containing phosphor-containing resin layer is located on the surface of the outdoor illuminating membrane material, the surface color becomes yellow due to the effect of the phosphorescent pigment. It was remarkably inferior, and was insufficient as an outdoor illuminating membrane material. In addition, during night illumination, since the internal illumination light is not directly applied to the phosphorescent phosphor-containing resin layer, the phosphorescent state is always insufficient, and the afterglow brightness is lower than in Example 2, and should be transmitted in the evening. When it stopped and became completely dark, it was insufficient as a film material that emits light by itself and serves as a mark of an evacuation passage or evacuation site.
