[0001]

TECHNICAL FIELD The present invention relates to a novel fire-resistant makeup method.

[0002]

2. Description of the Related Art When a structure such as a building or a civil engineering structure is exposed to a high temperature due to a fire or the like, there is a problem that the physical strength of the steel frame and the concrete of the structure is rapidly reduced. On the other hand, a method has been adopted in which a refractory coating material is applied to a substrate to delay a rise in the temperature of the substrate and temporarily suppress a decrease in physical strength. Typical methods include, for example, 1) inorganic fibrous substances such as rock wool, asbestos, glass fiber, 2) lightweight aggregates such as perlite and vermiculite, and 3) inorganic powder containing crystallization water in an inorganic binder such as cement. A wet refractory coating method is known in which a body or the like is appropriately mixed, kneaded with water, and a paste or slurry mixture composition is thickened on a substrate surface.

[0003] However, in the coating composition used in the above method, depending on the type of the material used, for example, the fire resistance performance for one hour on columns, beams, etc. of a steel reinforced concrete structure (one hour heating in a standard heating curve). In this case, when the steel material temperature is 350 ° C. or less on average and 450 ° C. or less at the highest temperature), a coating thickness of about 20 to 40 mm is required, which results in a considerable thickness. For this reason, a relatively large amount of coating material must be carried in when performing construction at a building site, which is very disadvantageous in terms of cost. In addition, due to the thickening, the construction part projects significantly from the base material, which may give a sense of oppression in appearance. Furthermore, there is a possibility that the coating layer may peel off or fall off after the application. Therefore, there is a need to develop a coating material composition that is lighter and thinner.

[0004] As another method for imparting fire resistance to a substrate,
2. Description of the Related Art There is known a method in which a coating film foams with a rise in temperature due to a fire or the like, and thereby a foamed fire-resistant paint which gives fire resistance to a substrate is applied to the substrate by various methods. The foamed refractory paint used for this contains a foaming component that decomposes to generate a nonflammable gas when the temperature rises, and a component that is carbonized to form a porous carbonized layer. That is, the fire extinguishing effect is exhibited by the generation of the noncombustible gas, and the heat insulating effect is exhibited by forming the porous carbonized layer by the carbonized component.

Therefore, according to the foamed fire-resistant paint, even if the initial coating film is usually as thin as several mm or less, an effective heat insulating layer can be formed by foaming at several times to several tens times by heating or the like in a fire. Can be formed. Therefore, there is an advantage that the coating film can be made extremely thin compared to a wet type fire-resistant coating material, the feeling of oppression is small, and a clean feeling can be obtained. Further, compared to the wet type refractory coating material, less material is required, and the problem of cost can be solved.

However, when applying the foamed refractory paint, it is necessary to make the thickness uniform in order to make the fire resistance uniform, so it is necessary to thoroughly control the thickness at the time of painting. For this reason, the painting work must rely on skilled craftsmen. In addition, since it is a wet coating method, there is a disadvantage that it takes time to cure and the like, and there is a limit in shortening the construction period.

[0007] In recent years, fireproof coating with dry sheets has been performed in place of such a wet coating method. This is a method of coating a dry sheet prepared in advance on a substrate. Examples of the dry sheet include non-combustible fibers in the form of non-woven fabric, non-combustible non-woven fabric, cloth-like material such as woven fabric impregnated with foamed refractory paint, and non-combustible material such as aluminum foil in sheet form. There are various types such as those obtained by laminating a foamed refractory paint on a cured product, but all of them are attracting attention because their thickness can be easily controlled and curing is not required. Among the fire-resistant coatings made of such dry sheets, those having a small thickness especially during construction and foaming to form a carbonized layer at the time of fire have been spotlighted.

[0008] Such a sheet is called a foamed refractory sheet. However, there are many demands for the construction to provide an aesthetic or design property at the time of construction, and it is necessary to provide a protective finish layer on the foamed refractory sheet. Is done frequently.

For example, according to Japanese Patent Application Laid-Open No. 7-276552, the protective finish layer is generally formed of a monochromatic paint that generally has a flat finish surface. Required.

[0010]

However, when the foamed refractory sheet is actually affixed to the construction site, a step is formed at the abutting portion, the overlapping portion, and the like of the sheet, resulting in unevenness. For this reason, a complicated method is used in which the non-land portion is scraped with a sander or the like to make the fireproof coating surface flat, and then the protective finish surface is formed. Such a method is always performed when the protective finish layer is formed of a monochromatic paint having a flat surface, but this causes a prolonged work period. In addition, the protective finish surface formed by a monochromatic paint is particularly focused on the protection of the foamed refractory sheet, and at present the design is not considered much.

Accordingly, it is a main object of the present invention to provide a fire-resistant makeup method which is excellent in design while giving excellent fire resistance.

[0012]

Means for Solving the Problems The present inventor has conducted intensive studies in view of the above-mentioned problems of the prior art, and as a result, has found that the above object can be achieved by a fire-resistant makeup method comprising specific steps. Was completed.

That is, according to the present invention, there are provided the following steps: (1) the first step of coating a skeleton with a foamed fire-resistant sheet, and (2) the second step of attaching a stone-finished finishing material to the skeleton to be provided with fire resistance. The present invention relates to a fire-resistant makeup method.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION (1) Frame to be given fire resistance The frame (substrate) to be given fire resistance includes all parts that can be made into a fire resistant structure in structures such as buildings and civil engineering structures. It does not matter whether it is a steel frame, a reinforcing bar, a wooden structure, or the like. The structural parts also include all parts such as walls, columns, floors, beams, roofs, stairs, and the like. In particular, the design is required for the part that is visible to the public.
Construction on floors, beams, etc. is effective. Most of such construction parts are made of concrete, metal, etc. In particular, parts and members made of metal (for example, H-shaped steel, steel round columns, steel prisms, etc.) are rustproofed in advance. Paint may be applied to perform rust prevention treatment.

(2) Coating with Foamed Refractory Sheet In the present invention, as a first step, the frame is covered with a foamed refractory sheet (also simply referred to as “sheet”). Thereby, fire resistance can be mainly given to the frame. The foamed refractory sheet used in the present invention is not particularly limited as long as it foams when the ambient temperature reaches a predetermined foaming temperature due to a fire or the like and forms a carbonized heat-insulating layer.

Specifically, it can be appropriately changed according to the site to be applied and the like. For example, JP-A-5-220879,
A foamed refractory paint as disclosed in JP-A-7-276552 or the like is formed into a sheet by coating in a known manner, and the foamed refractory paint is impregnated into a cloth such as a nonwoven fabric or a woven fabric. The sheet of the present invention can be used as a sheet of the present invention, or a sheet obtained by laminating them, or a sheet obtained by laminating them on a noncombustible cloth (including a metal foil or the like).

According to the present invention, in particular,
The one disclosed in No. 52 is preferable. That is, in terms of solid content, the flame retardant 20 per 100 parts by weight of the binder is used.
A sheet formed from a foamed refractory paint comprising 0 to 600 parts by weight, 40 to 150 parts by weight of a foaming agent, 40 to 150 parts by weight of a carbonizing agent, and 50 to 160 parts by weight of a filler can be suitably used.

The thickness of the foamed refractory sheet may be appropriately set depending on the application site and the like, but is usually about 0.1 to 2 mm.
Preferably, it is 0.5 to 1 mm. If the thickness is less than 0.1 mm, sufficient fire resistance cannot be obtained, and the strength of the sheet becomes low, making handling difficult. On the other hand, if it exceeds 2 mm, it may not be possible to obtain sufficient improvement in fire resistance performance corresponding to the thickness. However, if necessary, the thickness may be more than 2 mm.

As a method of coating the frame with the foamed refractory sheet, any method may be used as long as the performance of the sheet is not hindered. For example, a method of forming an adhesive layer with a known adhesive on at least one of the frame and the foamed refractory sheet, and attaching the foamed refractory sheet to the frame, nails, anchors, rivets,
A method of locking the foamed refractory sheet to the skeleton by a connecting member such as a screw may be used.

In covering the skeleton with the foamed refractory sheet, better fire resistance can be obtained if the skeleton is completely covered with the sheet. In this case, for example, the butted portions of the sheets may be overlapped with each other and bonded with an adhesive or the like, or filled with a fire-resistant putty material. It is also possible to bury the butted portion with a fire-resistant gap tape, a foamed fire-resistant sheet cut into a tape shape, or the like to cover the whole. The above-mentioned fire-resistant putty, fire-resistant gap tape and the like can employ the same composition as the foamed fire-resistant sheet.

(3) Affixing of stone-finished finishing material In the present invention, as shown in FIG. 1, for example, after a foamed fire-resistant sheet (B) is laminated on a frame to be provided with fire resistance, the design is mainly improved. A stone-like paste finishing material (A) is stuck to apply.

Further, in the present invention, prior to coating the foamed refractory sheet of the above (2), a laminated sheet in which a stone-finished finishing material is pasted on the sheet may be coated on the frame. In this case, it is not necessary to attach the stone-like finishing material again after the covering with the laminated sheet.

The stone-finished finishing material is not particularly limited as long as it has an effect of making inconspicuousness or the like generated when the foamed refractory sheet is adhered to the frame, and known materials can be used. . For example, a stone-like finish coating material applied or impregnated to a sheet material such as a nonwoven fabric or a woven fabric, a later-described reinforcing layer forming coating material and a stone-like finish coating material are laminated in advance, and between the two layers. In which a sheet-like material is sandwiched.

Examples of the stone-like finish coating material used in the above and above include: a) a water-based finish coating material that forms a stone pattern;
Among the various pattern paints, there may be mentioned those giving a stone-like design.

(A) Examples of the water-based finish coating material that forms a stone pattern include coating materials containing at least one of ground natural stones and colored aggregates as aggregates. Generally, what is called a natural stone-like coating material can be used as it is. This is a material in which aggregates such as pottery stone lysine (skin) are blended with a thick finish coating material, and has an aggregate color developing property by these aggregates, and the finish is about 0.5 to 6 mm in thickness. It can reproduce the texture of natural stones such as granite, Indian sandstone and marble (travertine).

Known pulverized natural stones can be used, for example, barite, limestone, kaolinite, talc, wollastonite, diatomaceous earth, quartz and the like.

The colored aggregate is not particularly limited as long as it is colored. Further, those manufactured by any method can be used. For example, silica sand, crushed stone, baked at high temperature a sodium silicate binder containing a highly heat-resistant pigment on the surface of granular materials such as glass beads, baked coating with aminoalkyd resin paint, etc., colored lacquer What omitted the baking process,
Colored coating with a siloxane crosslinkable reactive oligomer containing an alkoxysilyl group as a functional group and a main chain of acrylic, a pigment and a curing agent, crushed ceramics fired with pigments, crushed ceramic tiles Objects and the like.

In addition, silica sand, glass beads, crushed ceramics, resin beads, organic or inorganic expanded particles, or the like may be used as the aggregate, and may be added so as to have a stone-like pattern.

The average particle size of these aggregates such as ground natural stones and colored aggregates is usually about 0.05 to 5 mm, preferably about 0.5 to 5 mm.
Those having a size of 1 to 3 mm can be used alone or in combination. In some cases, particles having a particle size outside the above range may be used.

The above-mentioned water-based finish coating material is, in addition to the above-mentioned aggregate,
As the binder, a synthetic resin emulsion, a siliceous binder, or the like can be used. Also, if necessary, a coloring pigment,
In addition to the extender pigments, various paint additives can also be blended.

The synthetic resin emulsion is not particularly limited, and those known as paints can be used. Examples of the synthetic resin include polyvinyl acetate, polyacrylate, acryl-styrene copolymer, ethylene-vinyl acetate copolymer, vinyl acetate-acryl copolymer, ethylene-vinyl chloride copolymer, and acetic acid. Synthetic resins such as vinyl-veova copolymers can be used. These can be used alone or in combination of two or more. Acrylic, urethane, epoxy and other synthetic resins of an internal cross-linking type or a reaction curing type can also be used. Emulsions produced by any of the methods can be employed. For example, those obtained by emulsion polymerization of a monomer having a polymerizable unsaturated double bond, those obtained by dispersing a synthetic resin produced in advance in an aqueous dispersion medium using a dispersant, and the like are mentioned. In the present invention, a powder type emulsion can also be used. Water may be added to the powder emulsion at the time of coating.

As the coloring pigment, known inorganic or organic pigments can be used. Examples of the inorganic pigment include pigments such as titanium oxide, zinc oxide, carbon black, ferric oxide (bengala), lead chromate (molybdate orange), graphite, yellow iron oxide, ocher, ultramarine, cobalt green, and the like. Can be Examples of the organic pigments include azo pigments, naphthol pigments, pyrazolone pigments, anthraquinone pigments, perylene pigments, quinacdrine pigments, disazo pigments, isointrinone pigments, benzimidazole pigments, phthalocyanine pigments, and quinophthaline pigments.

The extender is not particularly limited, and any known extender can be used. For example, heavy calcium carbonate, clay,
Examples include kaolin, talc, sedimentable barium, white carbon, diatomaceous earth, and the like.

Examples of additives for paints include plasticizers, preservatives, fungicides, anti-algal agents, defoamers, leveling agents, pigment dispersants, anti-settling agents, anti-sagging agents, matting agents, and ultraviolet absorbers. Publicly known various additives such as an agent.

As described above, the water-based finish coating material that forms a stone pattern contains at least one of a crushed natural stone and a colored aggregate. Therefore, for example, one of natural pulverized material and colored aggregate may be used alone, or both may be used in combination. Further, several different kinds of natural stones and different kinds of coloring pigments may be used in combination with each other.

The application method using the above-mentioned aqueous finish coating material is not particularly limited, and may be in accordance with a known coating method. For example, it is possible to apply a mixture of a crushed natural stone, a colored aggregate, and a synthetic resin with a single color using a roller, a trowel, or the like, or to spray various single colors in combination to create various patterns.

In addition, the stone-finished finishing material may be provided with a reinforcing layer for reinforcing the stone-like design layer, if necessary. As such a coating material for forming a reinforcing layer, for example, a water-based finish coating material for forming a stone pattern, which excludes aggregates for forming a pattern such as a crushed natural stone or a colored aggregate, can be used.

B) As a colorful pattern paint, for example, JIS
K5667 (1995) A paint in which two or more colors of liquid or gel-like particles (colored particles) are suspended as specified in "Multi-colored paints". Can be suitably used. In this case, one colored particle may be a single color or have two or more colors. The multicolored paint composed of the dispersion medium and the dispersed particles as described above is, depending on the combination, an oil-in-water type (O / W type), a water-in-oil type (W / O type), and an oil-in-oil type (O / W type). O type) and underwater water type (W
/ W type). In the O / W type, a discontinuous phase is formed in a water-soluble dispersion medium such that a dispersed phase, which is a colored organic solvent-based paint, can be identified. The W / O type is obtained by dispersing a colored aqueous dispersion phase as a discontinuous phase in an oily dispersion medium.
In the O / O type, a gel-like substance colored by an organic solvent-based enamel is dispersed as a discontinuous phase using an oil-based dispersion medium so as not to be compatible with the dispersion medium. W /
The W type is obtained by dispersing a colored aqueous gel substance as a discontinuous phase in an aqueous dispersion medium.

In the present invention, any type of colorful pattern paint can be used, and a commercially available product can also be used, and it can be appropriately selected from these depending on the coating location, the type of foamed refractory sheet, and the like.

Examples of the sheet-like material used in the above and other examples include non-woven fabric and woven fabric, glass fiber non-woven fabric impregnated with acrylic resin, vinyl chloride resin and the like, non-woven fabric and polyester net laminated, synthetic fiber Cloth, cold gauze, metal thin plate and the like can be mentioned. When producing a stone-like applied finishing material using these sheet-like materials, it is also possible to make a tile tone with a decorative joint in advance.

As a method of sticking the stone-finished finishing material, any method may be used as long as it can be fixed to a foamed refractory sheet or the like as a base. For example, as shown in FIG. 1, it can be stuck using various adhesives (D). The adhesive used in this case is not particularly limited, and a known adhesive can be used. For example, acrylic-based, epoxy-based adhesives,
Alternatively, a sheet-like adhesive with release paper can be used. Further, the adhesive may be any of a water-based or solvent-based,
What is necessary is just to select suitably according to a use site | part etc. For example, when it is applied to an interior part, a water-based material is preferable.

As a specific bonding method, for example, an adhesive may be applied to the surface of the foamed refractory sheet, and then a stone-finished material may be adhered to the surface. An adhesive layer may be formed in advance, and the adhesive layer may be attached by pressure bonding. When the adhesive is applied, it is preferable that the adhesive is applied by a roller with little scattering or that an adhesive layer is formed in advance on the stone-finished finishing material side in consideration of the curing time and the like.

(4) Application of clear paint In the present invention, a foamed fire-resistant sheet is laminated on a frame to which fire resistance is to be imparted, and a stone-finished finishing material is adhered, and then a clear paint is applied for the purpose of protecting a decorative surface. It can also be applied. In particular, it is preferable to apply a clear paint for the purpose of protection when applied to a site outside the structure where weather resistance is required.

The clear coating of the present invention is not particularly limited, and known coatings can be used. For example, an acrylic resin-based, urethane resin-based, epoxy resin-based, acrylic silicon-based, fluorine-based paint, or the like can be used. In addition, any of an aqueous system and a solvent system may be used, but an aqueous system is particularly preferable when coating the interior part. Further, the clear paint is preferably of a non-staining type. Further, either a mat type or a gloss type may be used. In the present invention, in consideration of weather resistance, acrylic silicon-based, fluorine-based, and the like are preferable.

Coating with a clear coating may be performed by a known coating, and can be performed by various coating methods such as spray coating, roller coating, and brush coating.
In particular, when painting the interior part, it is preferable to carry out by roller painting, brush painting or the like. The film thickness of the clear paint may be appropriately set according to the site to be applied and the like, and is usually about 10 to 100 μm, preferably 20 to 5 μm.
It may be 0 μm.

(5) Coating of decorative undercoating material Following the step of laminating the foamed refractory sheet, for example, as shown in FIG. Materials (also simply referred to as "priming materials")
(C) may be applied to a foamed refractory sheet. By applying the undercoat material, it is possible to further improve the adhesion between the sheet and the stone-finished finishing material mainly after laminating the foamed refractory sheet. When forming a cosmetic joint, it is also possible to use a coloring type undercoating material to form the joint.

The undercoating material is not particularly limited as long as the adhesion to the sheet and the stone-finished finishing material can be ensured, and known materials can be used. For example, sealers, primers,
In addition to a base adjustment material, a surfacer, etc., a normal flat type paint can be applied. Further, either a clear type or a colored type may be used. Further, as long as the water resistance of the foamed refractory sheet is not impaired, it may be either water-based or solvent-based, and can be appropriately selected depending on the coating location and the like. For example, when installing the interior part, it is preferable to use a water-based material. In the case where joints are formed at the time of decorative finishing, the undercoat material may be colored in joint color. In the present invention, it is preferable to use an acrylic resin emulsion-based paint of a cross-linking type between particles, which is excellent in weather resistance, particularly considering that the undercoat material is exposed at joints.

The coating of the cosmetic primer material in the present invention may be carried out according to a known coating method, for example, by spray coating, roller coating, brush coating or the like. Especially,
When used for interior parts, roller coating, brush coating, etc. are appropriate in consideration of the time and labor required for curing.

(6) Cosmetic finishing with joints In the present invention, when sticking the stone-like finishing material to the foamed refractory sheet, the finishing can be performed while forming joints at regular intervals. The joint in the present invention may be a joint formed in such a manner that a piece of the refractory sheet covering the abutting portion of the foamed refractory sheet is exposed as shown in FIG. 3, or a base (foamed refractory sheet) as shown in FIG. Joints formed by exposing themselves are also included.

In the present invention, as shown in FIGS. 3 to 5, for example, when a joint formed by processing a stone-finished finishing material or a foamed refractory sheet itself is used as a joint, No formwork is required.

When a joint is formed, the base is usually exposed as a joint. Therefore, it is preferable to color the surface of the foamed refractory sheet or the decorative undercoating material, which is the base, in advance in the joint color.

In particular, according to the present invention, joints are formed at the butted portions of the stone-like applied finishing materials, and the joints are further joined with putty joints, urethane-based, epoxy-based, etc.
It is preferable to perform a sealing treatment with a known sealing material such as a silicone-based, butyl rubber-based, or modified silicone-based sealing material.

For example, a joint is formed by sticking a stone-like finishing material so that a part of the foamed refractory sheet as a base is exposed, and the joint is filled with joint putty or the like or cut into joint width. Can be covered with a foamed refractory sheet. Also, as shown in FIG. 3 or FIG. 4, the foamed refractory sheet and the stone-finished finishing material are laminated so that a step is formed in advance, and the recess formed by the step is used as a joint. The joint may be filled with joint putty or the like (F). Further, as shown in FIG. 5, after the foamed refractory sheet is completely covered with the stone-finished finishing material, slopes are respectively formed at both ends of the stone-finished finishing material, and the concave portions (slopes) formed by the slopes at both ends are formed. (V-shaped portion) may be used as joints and filled with joint putty or the like (H).

FIG. 4 shows an example in which the decorative undercoat is not formed. The foamed refractory sheet in which the decorative undercoat is laminated and the laminate in which the stone-like finish is laminated are shown. It may be used for processing.

[0055]

According to the fire-resistant makeup method of the present invention, it is possible to impart both fire resistance and design to a frame to which fire resistance is to be imparted. In particular, since the stone-finished finished material is used in combination with the foamed refractory sheet, the unevenness that occurs when the stone-finished finished material is covered with the foamed fire-resistant sheet can be made inconspicuous by the covering effect of the stone-finished finished material. As a result, the construction period can be shortened. In addition, natural texture can be given to architectural and civil engineering structures that tend to be inorganic.

The present invention is to impart fire resistance and design to a frame to which fire resistance is to be imparted by a fire-resistant makeup method, and is applicable to a frame to which existing buildings and civil structures are to be imparted with fire resistance. What is possible, of course, is a so-called “pre-coat” in which materials that form the building and civil engineering structures are first constructed at a factory and then assembled.

Pasted to be inserted into the side part. After the adhesive was dried and hardened, the joint portions became gray with a width of 15 mm, and the other portions formed granite-like uneven patterns. Also, the seam portion of the foamed refractory sheet was completely invisible.

Example 4 A rust-proof painted steel cylinder having a diameter of 400 mm was prepared.
As shown in FIG. 5, an acrylic resin-based adhesive is used as a guide and applied with a brush at a coating amount of about 200 g / m ² , and a stone-finished finishing material / foamed refractory sheet laminated sheet 3 having a width of 4
20 mm, 900 mm in length, and further polished the four sides of the part of the stone-finished finishing material 3 obliquely at an angle of 45 °, without gaps so that the long sides correspond to the longitudinal direction of the column. Pasted. After drying and hardening of the acrylic resin-based adhesive, a V-shaped joint formed at the abutting portion of the stone-finished adhesive finishing material 3 was filled with a gray-tone epoxy resin-based sealing material to perform a waterproof treatment. On the surface thus formed, a pattern in which a granite-like rectangular pattern and a gray joint intersected was formed. Also, the seam portion of the foamed refractory sheet was completely invisible.
