DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material having a suede-like appearance and having a particularly soft touch, and a method for producing the same. INDUSTRIAL APPLICABILITY The decorative material of the present invention can be used as an interior material of a vehicle, a building material for an interior, an exterior material of furniture furniture, home electric appliances, and the like, and a high-quality appearance can be obtained.

[0002]

2. Description of the Related Art Various methods have conventionally been employed to enhance the texture of interior materials of vehicles and interior building materials. Specific examples and problems will be described below. There is a method of implanting hairs on the surface of a base material such as an interior material or attaching a back skin to enhance the texture. However, in this method, costs and man-hours are increased, so that a low-cost one having a suede-like appearance that is easy to touch is required.

Therefore, there has been proposed a method in which a coating material in which microcapsules are dispersed is applied to the surface of a base material, heated to expand the microcapsules, and a decorative material having an uneven pattern on the surface is obtained. As such a method, a resin-based treating agent containing microcapsules is gravure-printed on the surface of a sheet made of a thermoplastic resin, which is heated to cause expansion of the microcapsules and softening of the resin, thereby producing a sheet surface. For forming fine irregularities on the surface (Japanese Unexamined Patent Publication No.
-76735),

[0004] The microcapsules are dispersed in a vinyl chloride resin paste, and the paste is printed on a backing material by gravure printing or the like, and the paste is gelled by heating the paste. A method of obtaining a decorative sheet having an appearance (Japanese Patent Application Laid-Open No. 62-28481), and

[0005] An undercoat containing microcapsules is applied to a substrate, and after the paint is cured, a topcoat is further applied, and then the microcapsules are expanded by heating to form a coating film having an uneven pattern. A forming method (Japanese Unexamined Patent Publication No. 2-303573) is known. This publication discloses that a preferable undercoating material which can be easily cured at a temperature lower than the expansion temperature of the microcapsule and which does not contain a solvent which may damage the outer shell of the microcapsule, particularly a ketone solvent or the like. And acrylic-epoxy water-based emulsion paints, urethane water-based emulsion paints, and acrylic ultraviolet curable paints. Further, as the top coat, enamel paints of melamine-alkyd type, acrylic type and the like are mentioned as preferable in appearance.

[0006]

However, in the above method, for example, in the case of vacuum forming or the like, the base material is stretched at a corner portion or the like where the drawing is large. There is a problem. In the above method, the expansion of the microcapsules and the softening of the thermoplastic resin as the base material are simultaneously advanced by heating. As a result, the resin softened by the expansion of the microcapsules is drawn to form irregularities, and the appearance and tactile sensation are not suede-like but hard.

Furthermore, in the above method, since the layer containing the expanded microcapsules is the surface layer of the sheet, the microcapsules may fall off the sheet surface during actual use. In addition, since the surface of the sheet does not slide well, a part of the microcapsules may be damaged when the sheet is rubbed in contact with another article. Furthermore,
Since this is a method of printing a paste containing microcapsules on a backing material, the printing machine is likely to be clogged and unevenness may occur on the printed surface. In addition, repairing the clogging of this plate requires a lot of trouble. Further, in the above method, although the damage and falling off of the microcapsules can be suppressed by the overcoating, the microcapsules may be damaged or fall off by rubbing with other articles because the surface does not slide well. . Moreover, the uneven pattern is rough and does not have a suede appearance.

The present invention has been made to solve the above problems, and has a matte and moist suede which has a fine and fine appearance on the surface and also has a soft touch. It is an object of the present invention to provide a decorative material having a tone-like outer surface and a method for producing the same.

And at least one of urethane beads and the intermediate layer is formed by dispersing thermally expanded microcapsules in a synthetic resin. Capsules are characterized by 2-30% by weight.

[0012] The manufacturing method of decorative material having a suede appearance of the sixth invention is a method of producing a decorative material according to any one of claims 1, 3 and 5, wherein the thermal expansion Applying the undercoat paint containing dispersed and contained microcapsules to a substrate, drying at a temperature lower than the thermal expansion temperature of the heat-expandable microcapsules, applying an overcoat paint, and applying the heat-expandable microcapsules to the base material. Heating at a temperature higher than the thermal expansion temperature of the capsule, forming a step of forming the intermediate layer and the surface layer, in this order, the topcoat paint

At least one of's is characterized that you have been blended.

The above-mentioned "substrate" is used for heating to expand the microcapsules and for drying and curing of a coating containing a synthetic resin or a thermoplastic elastomer for forming an intermediate layer and a coating for forming a surface layer. For example, a material that can withstand heating can be used. When the paint is diluted with an organic solvent, it is preferable to use one that is not easily attacked by the organic solvent. As the substrate, a resin sheet is preferable, and as the resin, polyvinyl chloride, which is particularly flexible and suitable for molding with a large drawing, is preferable. The surface of the substrate made of a polyvinyl chloride sheet or the like may be smooth or may have been subjected to graining or the like in advance. Further, the base material may be a single layer or may be composed of two or more layers. When there are two or more layers, each layer may be the same material or different materials. Further, each layer may be joined by an appropriate adhesive.

In the first and fifth inventions, the "synthetic resin" constituting the "intermediate layer" and in the third invention, the "thermoplastic elastomer" constituting the intermediate layer
Is a main component of the undercoat paint applied to the base material.
In the first invention, the type of the synthetic resin is 100%
The elongation must be above and its “100% modulus” must be within the above specified range. This 100%
When the modulus is less than 20 kg / cm ² , the intermediate layer is too soft, which causes a problem in strength, and it is difficult to obtain a suede-like appearance. On the other hand, the 100% modulus is 150k
If it exceeds g / cm ² , the intermediate layer becomes hard and does not have a suede-like appearance with a soft touch. Also, the thermally expanding microcapsules may force the hard resin to stretch, resulting in an undesirable grainy appearance. The 100% modulus of this synthetic resin is especially 60 to 8
It is preferably 0 kg / cm ² , and if the 100% modulus is in this range, it has a suede-like appearance,
A decorative material having a moderately soft touch and a high texture can be obtained.

Also, in the fifth invention, one of the synthetic resins
The 00% modulus is preferably in the range of ^{20 to} 150 kg / cm ² , but even outside this range, a decorative material having a suede-like appearance can be obtained. However, particularly when the 100% modulus exceeds 150 kg / cm ² , the decorative material has a hard touch, and the texture is reduced. In the fifth invention, the intermediate layer is made of a urethane resin,
It can be made of various synthetic resins such as acrylic resin and vinyl chloride resin.

Further, the thermoplastic elastomer in the third invention includes styrene thermoplastic elastomer, olefin thermoplastic elastomer, urethane thermoplastic elastomer, polyester thermoplastic elastomer, polyamide thermoplastic elastomer, 1,2-polybutadiene. Thermoplastic elastomer, vinyl chloride-based thermoplastic elastomer, fluorine-based thermoplastic elastomer, and the like. As the thermoplastic elastomer, in particular, those obtained by dissolving or dispersing these elastomers in an organic solvent or water to form a coating material are preferable.

The synthetic resin and the thermoplastic elastomer are obtained by drying or drying and curing the above-mentioned “undercoat” applied to the substrate. The type of such a coating material is not particularly limited, but in the first invention, after drying and curing, a coating material in which the 100% modulus of the synthetic resin falls within the above specific range can be used. As the undercoat paint, the "one-pack type urethane resin paint" of the second invention and the "paint containing at least one of a urethane-based thermoplastic elastomer and a vinyl chloride-based thermoplastic elastomer" of the fourth invention are particularly preferred. In the second invention, it is preferable to use, as the one-pack type urethane resin coating material, a coating material using a thermoplastic urethane resin and a coating material that does not form so many crosslinked structures in the resin by drying and curing. Thereby, a relatively soft intermediate layer is formed, and a decorative material having a soft touch is obtained.

The "microcapsules" forming the intermediate layer together with the synthetic resin or the thermoplastic elastomer are obtained by thermally expanding the heat-expandable microcapsules. The intermediate layer is made of a thermally expanded microcapsule and a synthetic resin or a thermoplastic elastomer that fills a space formed by the outer surface of the microcapsule. The heat-expandable microcapsules are spherical with a diameter of 5 to 50 μm, and expand 4 to 30 times by heating. In the present invention, it is particularly preferable that the diameter is 15 to 25 μm and that the body expands 8 to 15 times. If such a microcapsule is used, an intermediate layer having an appropriate thickness and flexibility can be obtained. can do.

The thermally expandable microcapsules are usually
It contains volatile hydrocarbons such as butane and isobutane, and its outer shell is a vinylidene chloride-acrylonitrile copolymer,
It is formed of polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile, etc., in the present invention,
Both can be used without any problems.

When the content of the intermediate layer is 100% by weight, the content of the microcapsules in the intermediate layer is 2%.
When the amount is less than the weight%, the uneven pattern formed on the surface of the decorative material is rough and small, and the suede-like appearance is impaired. On the other hand, when the content exceeds 30% by weight, damage and falling off of the microcapsules cannot be sufficiently suppressed, and the microcapsules cannot be put to practical use. The content of the microcapsules is preferably 5 to 25% by weight, particularly preferably 15 to 25% by weight. With the content in this range, a decorative material having a soft touch and a suede appearance can be obtained. .
In the fifth invention, in particular, the 100% modulus is 1
When using a hard resin exceeding 50 kg / cm ² , the content of the microcapsules is preferably in the range of 15 to 25% by weight.

The above “surface layer” is formed by the above “overcoat” applied to the surface of the dried undercoat. The overcoat is not particularly limited, but if the hardness, texture, and the like of the surface layer are significantly different from those of the intermediate layer, preferable characteristics of the intermediate layer are reduced.
Therefore, it is preferable to use a paint having similar hardness, texture, and the like when the microcapsules are heated for thermal expansion. In particular, if the undercoat paint and the overcoat paint are both a one-pack type urethane resin paint or a paint containing a urethane-based thermoplastic elastomer, especially if a resin component or an elastomer component having the same or similar composition is used, the same hardness and the like will be obtained. No, adhesion between the intermediate layer and the surface layer,
The adhesion is also improved, and the two layers are not easily separated. In addition, the effect of suppressing damage and falling off of the microcapsules dispersed and contained in the intermediate layer is also exhibited.

[0022] This surface layer, containing "at least one of silicon oil, silicon beads and urethane beads". As a result, the surface of the decorative material can be smoothly slid, the tactile sensation can be further improved, and the microcapsules can be prevented from falling off. Also, discoloration due to friction is suppressed, and scratches on the projections are also prevented.

The above-mentioned silicone oil or the like may be blended in the top coat which forms the surface layer, as in the sixth invention. The compounding amount may be such that the content of the surface layer formed by drying and curing the top coat paint is 100% by weight, and 1 to 50% by weight, preferably 10 to 30% by weight. When the content is less than 1% by weight, slippage is insufficient, and falling off of the microcapsules is not sufficiently prevented. Usually, a desired effect can be obtained with 20% by weight, and a sufficient effect can be obtained with 50% by weight.
In the fifth invention as well, the preferable content of the silicone oil and the like and the obtained functions and effects are the same.

The decorative material of the present invention can be constituted by a laminate of at least three layers consisting of a base material, an intermediate layer and a surface layer. When the intermediate layer is not sufficiently bonded to the base material, an adhesive layer is provided between these two layers.
It can also be a laminate of layers. Further, when the intermediate layer and the surface layer are not sufficiently bonded, an adhesive layer may be provided between these two layers to form a five-layer laminate. An appropriate adhesive may be selected and used depending on the material of both layers to be joined. As this adhesive, for example,
Resin adhesives such as epoxy resin adhesives, vinyl acetate resin adhesives, acrylic emulsion adhesives, and rubber adhesives such as chloroprene rubber adhesives, nitrile rubber adhesives, and natural rubber adhesives No.

In the sixth invention, the undercoat paint is:
As in the seventh invention, it is preferable that it is diluted with an organic solvent. Further, it is preferable that the top coat is also diluted with an organic solvent as in the eighth invention. As the organic solvent, toluene, methyl ethyl ketone, and the like, which are generally used for solvent-based paints, can be used. By diluting with a solvent in this way, it can be easily applied by a spray gun or the like. Therefore, a uniform coating film can be formed on the surface of the base material, and a dense, fine, and uniform uneven pattern can be formed on the surface of the decorative material.

The amount of the organic solvent used for diluting the coating material is not particularly limited, but it is not necessary to dilute the organic solvent more than necessary for application with a spray gun or the like. Is not preferred. When the top coat is diluted with an organic solvent, it is preferable to dry the microcapsules at a temperature lower than the thermal expansion temperature of the microcapsules to remove the organic solvent before the heating step in the sixth invention.

Further, the undercoat paint has a thickness of 30 to 10 in a dry state before the thermally expandable microcapsules thermally expand.
The overcoat may be applied so as to have a thickness of 0 μm, especially about 40 to 70 μm, and a dry thickness of about 5 to 20 μm, particularly about 10 μm. When the coating thickness is set to this level and the microcapsules are contained in the amount specified in the first, third, and fifth inventions, the microcapsules are heated,
By expansion, a fine uneven pattern is formed, a suede-like appearance, and when a specific synthetic resin or a thermoplastic elastomer is used, a decorative material having a soft touch feeling can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to examples. (1) Materials used As the base material, a polyvinyl chloride sheet having a surface subjected to grain processing was used. As the undercoat paint for forming the intermediate layer, a one-pack type urethane resin paint (manufactured by Tokusekisho Co., Ltd.) was used. The urethane resin obtained by drying and curing this paint has a 100% modulus of 80 kg / cm ^2.
Met. This 100% modulus is JIS K6
It is a value measured by 301.

The above-mentioned undercoating paint is used in an amount of 100
100% by weight of toluene was added, given as% by weight. In addition, when the urethane resin obtained by drying and curing the paint (this is the synthetic resin of the intermediate layer of the first invention) is 100% by weight, the heat-expandable microcapsules having the quantitative ratio shown in Table 1 are obtained. Was blended. The microcapsules used were manufactured by Nippon Ferrite Company and had a spherical diameter of 18 to 24.
μm, and the body expansion rate under heating conditions in this example is 8
It was twice.

The same one-pack type urethane resin paint as described above was used as a top coat for forming the surface layer. Toluene having the same ratio as described above was added to this overcoat, and in order to improve the slip of the surface of the decorative material, 20% by weight of the surface layer obtained by drying and curing the paint was 100% by weight. The following amount of urethane beads was blended. When an organic solvent is also added to the top coat as described above, it is preferable to provide a drying step for removing the organic solvent after applying the top coat as in the eighth invention.

[0031]

[Table 1]

(2) Production of decorative material Undercoat was sprayed on the surface of the base material by a spray gun, applied, and dried at 110 ° C. for 1 minute to remove toluene and other volatile components. The film thickness after drying was about 50 μm. Thereafter, the top coat was sprayed on the surface of the dried undercoat paint in the same manner by a spray gun, applied, and dried at 110 ° C. for 1 minute to remove toluene and other volatile components. The film thickness after drying was about 10 μm. Next, the decorative material was manufactured by heating the base material and the dried coating film composed of the undercoat paint and the topcoat paint at 180 ° C. for 1 minute to cure each paint and thermally expand the microcapsules. Table 1 shows the appearance, touch, etc. of the obtained decorative material.
It is described together.

The drying temperature and time of the above-mentioned paint can be appropriately set depending on the kind of the paint and, when diluted with a solvent, the kind of the solvent used. For example, in the case of the paint used in this example, the drying temperature and the drying time may be about 80 to 130 ° C. and about 1 to 5 minutes. The curing temperature and time of the paint can be appropriately set in consideration of the desired expansion rate of the heat-expandable microcapsules in addition to the type of the paint. In the case of the paints and microcapsules used in this example, the curing and expansion temperature and time can be set at 150 to 190 ° C. for about 30 seconds to 1 minute.

In addition, as a result of visual observation, the substrate has clear grained pattern irregularities and a glossy surface. On the other hand, a similar grain pattern was observed on the surface of the obtained decorative material, but there were some places where the fine grain pattern was not clear, and the surface was matte. In addition, the surface of the base material had a rather hard tactile sensation, but the decorative material had a moist and soft tactile sensation.

(3) Effect of Urethane Beads and the Like In the decorative material of the present invention, the influence of the urethane beads and the like on the sliding of the surface is great. The device shown in FIG. 2 (surface property measuring device, manufactured by Shinto Kagaku Co., Ltd., model “HEIDON-1”

(4) Discussion of the results in Table 1 According to the results in Table 1, the decorative materials of Experimental Examples 1 to 4 in which the 100% modulus of the intermediate layer is within the range of the first invention have a suede-like appearance. It can be seen that a product having a soft touch feeling is obtained. In particular, in the decorative materials of Experimental Examples 2 to 4 in which the content of the microcapsules is in the range of 3 to 30% by weight, a dense and uniform concavo-convex pattern is formed on the entire surface, and the appearance and touch are excellent. In addition, in the decorative material of Experimental Example 1 in which the content of the microcapsules was 2% by weight and the lower limit, the formation of the concavo-convex pattern was slightly insufficient and heterogeneous.

On the other hand, in Experimental Example 5 in which the content of the microcapsules slightly exceeded the upper limit of the first invention, a sufficient uneven pattern was formed, but a part of the microcapsules was damaged or dropped. Tendency to do so. In Experimental Examples 6 to 9, the content of the microcapsules is in an appropriate range of 20% by weight. However, the decoration using the undercoating paint or the topcoating paint, or a paint that becomes a hard cured coating film with small elongation is used for both the paints. Material. Therefore, these decorative materials,
Even if the one-pack type urethane resin paint is used for either one, the microcapsules will forcibly stretch the hard resin, and although it has a suede-like appearance, it also has a soft touch. It was not a decorative material. The elongations of the coating films obtained by drying and curing the two-pack type urethane resin coatings of Experimental Examples 6 and 7 and the acrylic resin coatings of Experimental Examples 8 and 9 were all less than 100%.
