[0012] Here, the fiber end material is a finely cut fiber used for clothing. For example, the end material of denim cut to 4 to 12 mm, preferably 6 to 10 mm, more preferably 7 to 9 mm can be used.

[0013] As pigments, black and blue are used, and when the ratio of the black component to the blue component is used in the range of 1:2 to 1:4, preferably 1:2.5 to 1:3.5, more preferably 1:2.7 to 1:3.3, especially when denim is used as the fiber end material, even if there is some variation in the shade of the raw denim fiber, the difference can be reduced, and the original color and texture of the denim fiber can be not significantly damaged, and it is possible to obtain a finished color with a more or less uniform color shade and unevenness characteristic of denim color.

[0014] The thickener functions as "nori" and carboxymethyl cellulose, an anionic water-soluble polymer obtained from natural cellulose as a raw material, can be used. As the thickener, a mixture of a high-viscosity thickener with a viscosity of 600 - 800 (mPa·s 1%, 25°C) and a low-viscosity thickener with a viscosity of 10 - 200 (mPa·s 1%, 25°C) is used in the range of the ratio of the high-viscosity thickener to the low-viscosity thickener of 1:0.55 - 0.80, preferably 1:0.60 - 0.75, more preferably 1:0.65 - 0.70. By doing so, only the water retention can be improved without increasing the viscosity, so the workability is good, and the film after drying is also relatively soft. Especially when denim is used as the fiber end material, it is possible to obtain a finished texture that does not damage the texture of the denim fiber. Here, even when constructing using only the high-viscosity thickener with a viscosity of 600 - 800 (mPa·s 1%, 25°C), construction is possible, but it is necessary to blend an amount that can impart a water retention capacity such that the kneading water does not drip. Therefore, since the viscosity after kneading increases very much, the workability deteriorates, and it has been confirmed that the finished texture after drying also becomes quite hard.

[0015] As the mineral-derived inorganic material, mica with a mesh size of 100 - 300, preferably 150 - 250, more preferably 180 - 220 can be used. Here, especially when denim is used as the fiber end material, by using mica, it is possible to be as close as possible to the specific gravity of the denim fiber and not damage the texture of the denim fiber. That is, when using denim as the fiber end material in particular, mica with a mesh size of 100 to 300, preferably 150 to 250, more preferably 180 to 220, has been confirmed to be suitable as a light, fine, and inconspicuous color mineral-derived inorganic material.

[0016] As the antifungal agent, those containing organic nitrogen and active sulfur as active ingredients can be used.

Advantages of the Invention

[0017] According to the present invention, the following effects can be achieved.

[0018] Since the fiber end material, thickener, and mineral-derived inorganic material are mixed at specific ratios, it is effective as a base material for a flame-retardant wall material.

[0019] In particular, when using denim as the fiber end material, by using black and blue pigments within a specific range, even if there are some variations in the shade of the original denim fiber as a raw material, the differences can be reduced, and the original color and texture of the denim fiber are not significantly damaged, and it is possible to obtain a finished color with unevenness in the color characteristic of denim with a substantially uniform color shade. In addition, by using mica within a specific range, the texture of the denim fiber can be prevented from being damaged. Also, by using a mixture of a high-viscosity thickener and a low-viscosity thickener as the thickener within a specific ratio range, the workability is good, the film after drying is relatively soft, and it is possible to obtain a finished texture that does not damage the texture of the denim fiber.

Brief Description of the Drawings

Modes for Carrying Out the Invention

[0021] Hereinafter, modes for carrying out the present invention will be described. Note that since the description here is one form in which the present invention is implemented, the present invention is not limited to this form.

Example

[0022] The flame-retardant woven fabric wall base material of Example 1 is composed of a fiber end material 1, a thickener 2, a mineral-derived inorganic material 3, a fungicide 4, and a pigment 5, as shown in the explanatory drawing of FIG. 1.

[0023] As the fiber end material 1, denim fibers obtained by cutting the end material of denim fabric to about 8 mm are used. As the thickener 2, a mixture of the raw material product number SN-60C and the raw material product number SLD-F1 of CMC Sunrose (registered trademark) of Nippon Paper Group is used. As the mineral-derived inorganic material 3, mica of 200 mesh is used. As the fungicide 4, the raw material product number R-ZPT of Bioside (registered trademark) of Taisho Technos Co., Ltd. is used. As the pigment 5, a mixture of blue and black is used.

[0024] The formulation is 120.00 kg (55.2%) of denim fiber, 19.60 kg (9.0%) of SN-60C, 13.23 kg (6.1%) of SLD-F1, 56.00 kg (25.7%) of mica, 0.70 kg (0.3%) of R-ZPT, 6.00 kg (2.8%) of blue pigment, and 2.00 kg (0.9%) of black pigment.

[0025] Next, a method for constructing a flame-retardant woven fabric wall using the above flame-retardant woven fabric wall base material will be described.

[0026] For a smooth wall to be constructed such as a gypsum board, as a base treatment, Cotegaard (trade name) of Shinco Co., Ltd., a one-component type mixed with a powder resin, is applied. The application of Cotegard is based on a standard mixing water volume of 4 to 4.5 liters per 1 bag (5.5 kg) of Cotegard. After thoroughly kneading while gradually adding less water than the standard water volume, add the remaining water to adjust to a state where it is easy to apply. After kneading, let it stand for about 30 minutes and then start applying to complete the base treatment.

[0027] By performing the base treatment with the above-mentioned Cotegard, even when the flame-retardant woven fabric wall base material of this example is applied to a smooth wall surface to be constructed such as a gypsum board, the workability becomes very good. That is, it has been confirmed that when applying to a smooth wall surface to be constructed such as a gypsum board without performing the base treatment with Cotegard, since there is no catch on the base, slippage occurs on the denim fibers, transparency appears on the construction surface, fiber deviation occurs, and the construction becomes extremely difficult.

[0028] For 700 g of the compounded flame-retardant woven fabric wall base material, add 5 liters of water and knead it up. Apply it to the wall surface where the base treatment is completed using a trowel to complete the construction. The wall surface constructed with the flame-retardant woven fabric wall base material is flame-retardant while leaving the texture of denim, and has obtained the flame-retardant certification RM-9364, non-combustible certification NM-8575, and quasi-non-combustible certification QM-9815.

[0029] The wall surface using the denim edge material constructed with the flame-retardant woven fabric wall base material of this example becomes soft by spraying water even when there are scratches or holes, so the repair is easy. Also, when removing, it can be easily peeled off by spraying water, so it can be easily removed. Furthermore, the removed flame-retardant woven fabric wall base material can be reused by adding water and kneading it up, and can function as a recyclable plaster material.
