Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of forming a thick and deep, for example, natural stone-like decorative material as a decorative material for decorating an interior or exterior wall or floor of a building or for finishing a surface of a building. In addition, the present invention relates to a coating material suitable as a coating material applied to the surface side when forming the decorative material.

[0002]

2. Description of the Related Art (1) A coating material containing a synthetic resin emulsion and a marble powder or other aggregate is coated on a cold gauze made of synthetic fiber, glass fiber or other inorganic fiber, nonwoven fabric, other fabrics, or an appropriate solid substrate. The decorative material, which is applied to the natural stone-like pattern by spraying gun or iron, etc. by appropriate means, is used to decorate the interior or exterior wall or floor of a building or the surface of a building or the surface of a building. (JP-A-4-76151, JP-A-3-2795)
No. 61).

(2) There is also a known finishing method for applying various natural stone patterns by applying a synthetic resin emulsion and an aggregate directly onto the interior / exterior wall surface or floor surface of a building or the surface of a building using a synthetic resin emulsion and an aggregate. I have.

(3) Further, a first coating material containing a synthetic resin emulsion and an aggregate is applied to, for example, a wall surface or other construction surface of the above-described base material, building, or structure, and then coated. A base layer is formed, and a second coating material having a different color tone is applied to the base layer containing a synthetic resin emulsion and an aggregate on the base layer in a substantially island-like pattern with a thinner thickness, and dried, and the surface is formed in an island-like form. A decorative material having a pattern has also been proposed.

(4) A method has also been proposed in which after forming an undercoat layer on a material or on it, a decorative material is sprayed over the entire surface with a coating material containing artificially colored mica flakes and a synthetic resin emulsion. .

[0006]

According to the above-mentioned methods (1) and (2), it is possible to finish the surface of a building or a building having an appearance and texture close to that of a natural stone. In this case, it is not possible to impart the characteristic scaly brilliancy exhibited by the crystal part developed on the cleavage plane.
That is, for example, the most typical one of granite and the like is made of fine crystals such as feldspar, quartz, muscovite and biotite, and exhibits a peculiar scale-like glitter.

In the method (3), an island pattern is formed on the surface. However, since an aggregate having a relatively small particle size is generally used, the second coating is performed as if an ordinary coating was applied. Since the part where the material is applied conceals the base, the border of the pattern is relatively clear, and there is a problem that it is difficult to form a well-balanced and well-balanced pattern with the base layer. . In addition, there is a problem that scaly glitter cannot be imparted as in the cases (1) and (2).

In the method (4), since only artificially colored mica flakes are used, the artificially colored mica has poor transparency and completely hides the color tone of the underlying layer. In addition to the problem that it becomes heterogeneous in terms of harmony, it can not express a surface decoration pattern with a calm and heavy, but also because it is sprayed on the entire surface of the underlayer, the glittering feeling becomes too strong However, there is a problem that a calm feeling and a heavy weight are lost, and when used in a building, the feeling becomes restless.
Even if an aggregate is used together with this, substantially the same problem occurs.

The present invention solves the above-mentioned problems, and has a scaly brilliant property, and can form a harmonious and calm island-like pattern which is well compatible with the underlying layer, and is therefore a solid pattern as a whole. The present invention provides a method for forming a decorative material having good durability, capable of forming a calm decorative material, and a coating material suitable as a coating material applied to a surface side of the decorative material when the decorative material is formed. The purpose is to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, when a decorative material is formed on a substrate, a first coating material containing a synthetic resin emulsion and an aggregate and / or a pigment is applied as the substrate. There is no particular limitation as long as it can be used, and, for example, a substrate used in the manufacture of this type of conventionally used building or decorative material for finishing the surface of a building can be used in the same manner. Specifically, for example, fabrics and nonwoven fabrics made of synthetic fibers and inorganic fibers, for example, specifically, cold gauze and nonwoven fabrics made of acrylic fibers and polyester fibers, glass fiber fabrics, glass wool nonwoven fabrics, fabrics such as synthetic paper, and fabrics Substrates other than the above are, for example, concrete panel extruded cement boards, gypsum boards, silicate boards (calcium silicate boards), aluminum sheets, zinc-plated steel sheets and other metal sheets, metal wire mesh, expanded metal, wood plywood, rubber And a synthetic resin sheet. Also, without using a base material, directly on the surface of a building or a structure, for example, a building interior / exterior wall surface and floor surface, a support surface, a fence surface, a residential land development slope, a building retaining wall, an elevated structure. The first coating material used in the present invention is applied to the surface of a wall or a pillar exterior of a road or a bridge, an outer wall of a pedestrian crossing bridge, an entrance of a tunnel, or the like. A first coating material can also be applied.

The synthetic resin emulsion constituting the first coating material and the second coating material is not particularly limited, but preferably has properties such as weather resistance, alkali resistance, water resistance, and adhesiveness after drying. , A synthetic resin emulsion which satisfies flexibility, water absorption resistance, etc. is preferable, for example, an acrylic resin emulsion (including an acrylic-urethane resin emulsion and an acrylic-silicone resin emulsion), a vinyl acetate resin emulsion, and a vinyl chloride resin Emulsions and urethane-based resin emulsions. Above all, although acrylic resin emulsions are relatively inexpensive, they are excellent in terms of weather resistance and are used for a long time, such as when applied as a decorative layer for surface finishing of buildings and structures such as interior and exterior walls or floors of buildings. And is preferred.

Examples of the aggregate include inorganic materials and plastic materials such as marble powder such as cold water stone, granite powder, other natural stone powder, silica sand, glass powder, ceramic powder, and plastic flakes (including colored ones). It is preferably used.
Of course, these may be used in combination, or aggregates having different colors may be used in combination. The size of the aggregate used for the first coating material is not particularly limited, but a particle having a particle size (the major axis, that is, the maximum diameter portion) of about 0.01 mm to 3 mm is preferably used.

When a pigment is used as the first coating material component without using the aggregate or together with the aggregate, the pigment is not particularly limited, and various extenders and coloring pigments can be used. Of course, these may be used in combination. The size of the pigment particles can be any of the commonly used pigment particle sizes, and is usually much smaller than the aggregate. Although not particularly limited, generally commercially available pigments have a particle size of about 0.1 to 20 μm.

The size of the aggregate used for the second coating material is as follows:
Particle size 0.1-3 mm, more preferably 0.2-1 mm,
Even more preferably, it is necessary to use an aggregate of 0.2 to 0.6 mm, and in particular, it is important to use a large aggregate of 0.1 mm or more. When used, the second paint is applied as if a normal paint was applied.
Since the part where the coating material is applied hides the base,
The boundary of the pattern is relatively clear, a pattern with a very different feeling as if it was attached is formed, it is difficult to form a well-balanced and calm pattern with familiarity with the underlayer, which is not preferable . On the other hand, if the particle size exceeds 3 mm, projections appear on the surface and roughness is undesirably increased. That is, by using a slightly larger aggregate having a small particle size, the hiding power is reduced, and when an island-like pattern made of the second coating material is formed, transparency is maintained. A well-balanced and calm island-like pattern with good familiarity with the stratum can be formed. This is because the hiding power of the second coating material is relatively small, and the outline of the island-shaped pattern formed of the second coating material formed on the base layer looks blurred. If not more than 60% by weight of non-artificial color is used, these are transparent, so they do not completely cover the surface of the underlayer, and are well-adapted to the underlayer and harmonious and calm. A pattern can be formed. In particular, as the aggregate material of the second coating material, it is particularly preferable to use an aggregate in which 65% by weight or more based on the total weight of the aggregate is selected from the group consisting of cold water stone, silica sand, and glass powder. . These have relatively good light transmittance among aggregates, are transparent or translucent, have relatively small hiding power to the base, do not completely hide the surface of the base layer, and have good compatibility with the base layer. It is particularly preferable because a clear and calm island pattern can be formed. The relatively large particle size of the aggregate used for the second coating material in order to make the concealing property to the underlying layer relatively small is generally required in order for the pigment for coating to improve the concealing power. 0.1 to 2 as described above.
It is apparent from the fact that the aggregate of the second coating material used in the present invention is 0.1 mm or more, that is, 100 μm or more.

Although the mixing ratio of the aggregate and the synthetic resin emulsion constituting the first coating material differs depending on what kind and what kind of feeling of the decorative material is used, the ratio of the synthetic resin emulsion is not limited. The solid content is preferably about 5 to 20 parts by weight, particularly preferably about 5 to 10 parts by weight, based on 100 parts by weight of the aggregate.

By adopting a preferred embodiment in this range, the aggregate can be firmly held by the synthetic resin matrix,
Therefore, it is possible to obtain a decorative material that is not too brittle and has a durable strength while maintaining a heavy and deep texture. If the amount of aggregate is too large, the proportion of the synthetic resin that also functions as a binder will decrease, resulting in a decrease in the mechanical strength of the obtained decorative material or flexibility (flexibility is low when applied to curved surfaces. ). On the other hand, if the proportion of the aggregate is too small, the heavy and deep texture tends to decrease, and the coating containing the synthetic resin emulsion and the aggregate is preferred. When the material is dried and solidified after being applied to the substrate, shrinkage and the like tend to occur, and cracks tend to occur.

When a pigment is used, the mixing ratio of the pigment constituting the first coating material and the synthetic resin emulsion is the same as that of an ordinary paint for a paint, and is not particularly limited. The ratio of the synthetic resin emulsion is 20 to 60 parts by weight per 100 parts by weight of the pigment in the resin solid content, although it differs depending on what kind of hand the decorative material has.
The amount is preferably about part by weight, particularly preferably about 40 to 50 parts by weight. When the aggregate and the pigment are used in combination, the balance may be appropriately determined such that the addition amount of one of them is increased as the usage amount of the other increases in each of the above ranges.

The first coating material in which the aggregate and / or the pigment is blended with the synthetic resin emulsion may further contain a filler, a film-forming aid, a thickener, a defoaming agent, a pH adjuster, etc., if necessary. Or an appropriate solvent or the like may be added to adjust the viscosity. These additives are substantially the same in the second coating material.

As the thickener, for example, a methylcellulose-based thickener (eg, “Hymetrose 90SH-3000”)
0 ", manufactured by Shin-Etsu Chemical Co., Ltd.), as a film-forming aid, for example, butyl carbitol acetate, as a defoaming agent, for example," Nopcosant NXZ "(manufactured by San Nopcosan), etc. For example, concentrated aqueous ammonia is preferably used, but is not limited thereto.

Next, the mica flakes to be incorporated in the second coating material are preferably those having a size (major axis) of 0.5 mm or more, and if too small, the effect of exhibiting flaky luster is not sufficiently exhibited. . Those which are usually easily available are up to about 10 mm in size. Therefore, a mica flake having a size (major axis) of about 0.5 to 10 mm is preferably used.

Examples of the mica flakes include crushed natural mica such as muscovite, phlogopite and biotite (non-artificial colored mica) or artificial coloring obtained by artificially coloring them with a paint containing a pigment. Combination with mica flakes is also possible. Examples of the color of the artificially colored mica include white, black, yellow, red, and beige. However, in the present invention, the mica flakes must be non-artificially colored mica flakes at least 60% by weight. Natural mica flakes, which are not artificially colored, are transparent and do not completely conceal the surface of the underlayer, forming a well-balanced and well-balanced island pattern with the underlayer You can. Contrast can be given by using artificially colored mica in combination,
When used in combination, it is necessary that the total weight of the mica flakes used is 40% or less.

The size of the mica flakes to be used may be changed depending on the texture to be developed.
For example, a mica flake having a larger size, for example, a size of 4 to 10 mm may be used when a material having a size of about 4 mm is mainly used or a texture in which a larger crystal exists is desired. However, since a large-sized one may clog the nozzle of the spray gun, in such a case, an appropriate application method such as application using a brush or a trowel may be adopted.

The mixing ratio of the synthetic resin solid content, the aggregate and the mica flakes of the synthetic resin emulsion constituting the second coating material is 100 parts by weight of the aggregate having a particle size of 0.1 to 3 mm, and the resin solid content is 15 parts by weight. A ratio of mica flakes of 5 to 50% by weight based on the weight of the synthetic resin emulsion and the aggregate is preferably 60 to 60 parts by weight. If the ratio of the mica flakes is too large, the adhesion to the surface of the undercoat layer formed from the first coating material tends to decrease, and if the ratio of the mica flakes is too small, the effect of using the mica flakes is reduced. It tends to be smaller.

As the mica flakes, a transparent mica flake close to colorless, which is called muscovite as described above, or a colored non-artificial colored mica flake may be used.
The colored non-artificial colored mica flakes or artificial colored mica flakes are 1
Colored mica flakes may be used, or mica flakes of two or more colors may be used in combination. Of course, colored or artificially colored mica flakes may be used in combination with mica flakes having nearly colorless transparency. However, as described above, 60% by weight or more of the mica flakes must be non-artificially colored mica flakes.

The color tone after drying of the underlayer formed from the first coating material and the color tone after drying of the layer of the island pattern portion formed from the second coating material are different from each other. It is preferable to use them. Here, different color tone means hue,
At least one of lightness and saturation should be different. When the color tone is different, the color tone is different between the portion where the aggregate appears on the surface and the portion where only the resin is present in the base layer, and the island-like shape formed from the second coating material is also microscopically observed. If you look at the pattern part microscopically, the part where the mica flakes appear on the surface,
The color tone is different between the part where the aggregate appears on the surface and the part where only the resin is used, but instead of taking such a strictly microscopic view, the overall appearance of the underlayer with the naked eye It suffices that the color tone after drying and the color tone after drying of the layer of the island pattern portion formed from the second coating material be different.

Then, the second coating material is not applied to the entire surface of the underlayer formed from the first coating material,
It is necessary to apply in an almost island-like pattern at a ratio covering 20 to 80% of the surface area. When the second coating material is applied to the entire surface of the underlayer or at a ratio exceeding 80% of the surface area, the glittering feeling becomes too strong, and the calm feeling and the heavyness are reduced. They are lost and feel restless when used in buildings and structures. On the other hand, if the coating ratio is less than 20%, it is not preferable because the effect of exhibiting the characteristic scale-like brilliancy cannot be sufficiently exhibited.

Application amount of second coating material (approximate coating thickness)
It has an average value per underlying layer surface 1 m ² in value after drying 10
About 0 to 800 g / m ² is preferable. The value of the applied amount is the applied amount of the second coating material actually applied per 1 m ² of the underlayer surface. Since the second coating material is applied in an island pattern, the surface of the underlying layer has a portion where the second coating material is applied and a portion where the second coating material is not applied. It does not indicate the amount of application of only the portion where the second coating material is applied to the surface of the underlayer, but indicates the amount of the second
Is a value corresponding to the average value of the portion where the coating material is applied and the portion where the coating material is not applied. Therefore, the value of the application amount only in the portion where the second coating material is applied is larger than this.

In order to facilitate understanding of the present invention, a method of forming the decorative material of the present invention using the above-described materials will be described with reference to the drawings. FIG. 1 is a schematic sectional view showing a step of forming the decorative material of the present invention.

As shown in FIG. 1A, a first coating material is sprayed on the base material or the work surface 1 using, for example, a spray gun to form an underlayer 2. As shown in the figure, the surface of the underlayer 2 is preferably formed with an appropriate uneven pattern, but may be flat in some cases. Of course, instead of using a spray gun, it may be applied by trowel coating, roller application, brush application, or other appropriate means.

In FIG. 1A, 2a is an aggregate of the base layer 2 formed from the first coating material, and 2b is a schematic representation of a synthetic resin component. In reality, the underlayer is usually opaque because the aggregates 2a are so finely packed that they are so fine that they contact each other.

Next, as shown in FIG. 1B, before or after the underlayer 2 is dried, a second layer containing aggregate, mica flakes and a synthetic resin emulsion on the surface side thereof is formed. The coating material is applied to the island pattern 3. In FIG. 1 (b), 3a is an aggregate,
3b is a mica flake, and 3c is a schematic representation of a synthetic resin component. The application means may be any means such as a spray gun, a trowel, a brush, etc., as long as they can form an island pattern.
Note that the island shape is preferably an irregular island pattern, but may be a fixed island pattern such as a ball shape if necessary.

The size of the island pattern in the plane direction is not particularly limited, but is usually preferably in the range of about 20 to 2 mm in diameter. Since it is an indefinite shape, it cannot be strictly determined even if it is called a diameter, but if it were to be said, the diameter would be measured at two locations in the vertical and horizontal directions, and the average value would be a measure of the diameter.

When the second coating material is applied to the island pattern 3 before the underlayer 2 is dried, it may be dried as it is. In this case, the adhesion between the base layer 2 and the second coating material layer is good, and no special treatment is required. On the other hand, when the second coating material is applied to the island pattern 3 after the base layer 2 is applied and dried, at least a portion applied to the island pattern before the applied second coating material is dried. Press on top and dry. As the pressing means, an appropriate pressing means such as a roller hanging or pressing with a trowel can be adopted. Pressing is performed to improve the adhesion between the base layer 2 and the second coating material layer. In the case of pressing by roller hanging, usually, a sponge roller is suitably used. Even when the second coating material is applied to the island pattern 3 before the underlayer 2 is dried, at least the portion applied to the island pattern before drying is applied in the same manner as described above. Pressure treatment may be performed.

FIG. 2 is a schematic plan view of the decorative material of the present invention obtained as described above, as viewed from the front side. FIG.
Has shown an example in which three types of mica flakes are used as the mica flakes 3b. That 3b ₁ is non-artificial colors biotite flakes, 3b ₂ is thin, 3b ₃ artificial coloring biotite shows a slice of transparent non-artificial colors muscovite nearly colorless.

The decorative material of the present invention thus obtained has a solid appearance such as natural stone tone, and has a scaly brilliancy exhibited by a crystal part unique to natural stone. 0.1mm called particle size 0.1-3mm as aggregate of
Since the above-mentioned aggregate is used, the hiding power to the underlying layer is relatively small, and the 60%
Since the weight% or more is non-artificial colored mica flakes, it has a sense of transparency, so it does not completely conceal the surface of the underlayer, and the border around the pattern also has a blurred tone, and it is well blended with the underlayer. An isolated and calm island pattern can be formed, and thus a thick and calm decorative material can be formed as a whole. Incidentally, mica is a layered silicate mineral and has the property of being easily peeled off into thinner flakes in layers, but in the case of the method for forming a decorative material of the present invention, mica flakes are present only on the surface side. So, even if mica peels off the wall,
The mica flakes on the lower side remain, and therefore, can maintain the scaly brilliancy and do not peel off to the underlying layer, so that a durable decorative material can be formed, and it can be used for buildings and structures. It is possible to form a decorative material that is useful for finishing the surface of, for example.

Further, if necessary, a top coat layer may be formed by thinly coating the surface of the decorative material thus formed with a synthetic resin emulsion capable of forming a transparent resin layer after drying such as a so-called clear paint. . The top coat layer is preferably applied after at least the surface of the formed decorative material has been dried.

As the synthetic resin emulsion used for the top coat layer and capable of forming a transparent resin layer after drying, the above-described synthetic resin emulsions exemplified for the first and second coating materials can be used. The top coat layer is used for imparting surface gloss to decorative materials and for further imparting properties such as weather resistance, water resistance, and stain resistance, but can be applied to all types of decorative materials. Not required.
