DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a view showing an example of a metal-coated yarn manufacturing sheet according to the present invention.
In FIG. 1, the code | symbol 10 has shown the sheet | seat for metal-coated yarn manufacture. The sheet 10 for producing a metal-coated yarn includes a film 1, a metal thin film 2 provided on the film 1, and a first coating layer 3a and a second coating layer 3b provided on the metal thin film 2. It consists of the coating layer 3.
[0014]
The material of the film 1 is not particularly limited. For example, a film made of a synthetic resin such as polyester, polyethylene terephthalate, nylon, polyvinyl chloride, OPP (biaxially stretched polypropylene), CPP (unstretched polypropylene), or vinylon is preferable. Used for. Among these, polyester and polyethylene terephthalate are preferable because they are thermally stable and easy to form and handle the first and second coating layers 3a and 3b.
[0015]
The thickness of the film 1 is preferably 8 μm or less. More preferably, it is about 4-7 micrometers. A thickness exceeding about 8 μm is not preferable because the flexibility of the metal-coated yarn 20 becomes insufficient.
[0016]
The type of the metal thin film 2 is not particularly limited, and is selected from, for example, Cu, Ag, Zn, Sn, Ti, Al, Pd, Pb, Ni, Cr, Au, Pt, Fe, Co, Mo, and Zr. A seed or two or more alloys are preferred. A metal halide, complex, oxide, sulfide or the like may be formed on the surface of the metal thin film 2.
[0017]
When the metal-coated yarn manufacturing sheet 10 shown in FIG. 1 is used for the production of gold and silver yarn, the metal thin film 2 has a golden or silver luster, for example, Cu, Ag, Zn, Su, Ti or the like is preferably used. Is done. Among these, Ag is preferable because it can obtain a deep gloss peculiar to Ag that is difficult to obtain with other metals. In this case, if one or both of Sn and Ga are added to Ag in a total amount of less than 50 wt%, the corrosion resistance of the silver thin film itself is improved and the effect of preventing discoloration is obtained. When the addition rate is more than 50 wt%, the gloss of the silver thin film changes and the aesthetic appearance is lowered.
[0018]
The thickness of the metal thin film 2 is not particularly limited, but is preferably about 100 to 1500 mm. More preferably, it is about 300 to 1000 mm. If the thickness of the metal thin film 2 is less than about 100 mm, the gloss and corrosion resistance of the metal-coated yarn-producing sheet 10 are lowered, which is not preferable. On the other hand, in the case of forming by vapor deposition, even if the thickness of the metal thin film 2 is larger than 1500 mm, the effect of improving the aesthetics and the effect of improving the corrosion resistance are not obtained, and this is not preferable because only the cost increases. Moreover, although the formation method of the metal thin film 2 is not specifically limited, a vapor deposition method etc. are suitable.
[0019]
The material of the first and second coating layers 3a and 3b is not particularly limited. For example, polyester resin, butyral resin, acrylic resin, epoxy resin, urethane resin, urea-melamine resin, amino resin, phenol resin, vinyl chloride resin, Polyacetal resin, polycarbonate resin, silicon resin, vinyl acetate resin, fluororesin, styrene resin or the like alone or a mixture is preferably used.
[0020]
Furthermore, one or both of the first coating layer 3a and the second coating layer 3b contain a silane coupling agent in the resin as the main component.
As the silane coupling agent, one having a starting temperature of reaction for forming a network structure (stitch structure) with the resin as the main component is lower than the curing temperature of the resin. By containing a silane coupling agent in the resin, when the resin is cured, the resin has a reactive group such as a hydroxyl group, an amino group, an isocyanate group, and dienes at a temperature lower than the curing temperature of the resin as the main component. It is presumed that the silane coupling agent is bonded to each other and the silane coupling agents are bonded to each other to accelerate the curing of the resin and form a dense resin film after curing.
[0021]
As the silane coupling agent, RSiX ₃ (wherein R represents an organic functional group such as a vinyl group, a glycidoxy group, a methacryl group, an amino group, and a mercapto group, and X represents a chlorine and alkoxy group). Those represented by the formula are preferably used. More preferably, it is a silane coupling agent in which R is a glycidoxy group or an amino group.
The addition amount of the silane coupling agent is preferably in the range of about 0.05 to 2%. More preferably, it is about 0.1 to 0.15% of range. When the addition amount is less than about 0.05%, the curing temperature of the resin as the main component cannot be sufficiently lowered, and the film tends to become wrinkled. In addition, the effect of forming a dense resin film becomes insufficient, and it becomes difficult to obtain sufficient durability. On the other hand, an addition amount exceeding 2% is not preferable because it only increases the cost.
[0022]
As described above, the silane coupling agent is contained in one or both of the first coating layer 3a and the second coating layer 3b.
For example, when the silane coupling agent is contained in both the first and second coating layers 3a and 3b, it is more durable than that contained in only one of them. Can be improved.
When at least the second coating layer 3b contains a silane coupling agent, the second coating layer 3b forming the surface of the metal-coated yarn manufacturing sheet 10 becomes a dense resin film, and the metal-coated yarn The entire surface of the manufacturing sheet 10 on the second coating layer 3b side can be protected, and the durability can be effectively improved.
Furthermore, in the case where the silane coupling agent is contained only in one of the first coating layer 3a and the second coating layer 3b, the step of containing the silane coupling agent as compared with the one contained in both, The amount of the silane coupling agent used can be reduced, and the silane coupling agent can be made inexpensive.
[0023]
The thickness of the first coating layer 3a is preferably about 0.05 to 2.5 μm. More preferably, it is about 0.1 to 1.5 μm. A thickness exceeding about 2.5 μm is not preferable because the flexibility of the metal-coated yarn 20 becomes insufficient. On the other hand, when the thickness is less than 0.05 μm, a sufficient protective effect cannot be obtained and durability is lowered, which is not preferable.
Moreover, it is preferable that the thickness of the second coating layer 3b is approximately the same as that of the first coating layer 3a.
[0024]
Such a metal-coated yarn manufacturing sheet 10 has the following effects because one or both of the first coating layer 3a and the second coating layer 3b contains a silane coupling agent. It becomes.
(1) The coating layer containing the silane coupling agent can be formed at a temperature lower than the curing temperature of the resin as the main component, and the film 1 becomes wrinkled by the heat when forming the coating layer. Can be prevented. Therefore, the thickness of the film 1 which has been about 12 μm can be reduced to 8 μm or less, and the metal-coated yarn manufacturing sheet 10 having excellent flexibility can be obtained.
(2) By forming a network structure (stitch structure) between the resin and the silane coupling agent, a dense resin film can be formed, and a sheet 10 for producing metal-coated yarn having excellent durability can be obtained. It is done.
[0025]
In the metal-coated yarn manufacturing sheet 10 described above, the coating layer 3 is composed of two layers of the first coating layer 3a and the second coating layer 3b. The thin film 2 can be protected over a long period of time, and is more excellent in durability.

Among these, ZnO, SnO _x (0 <x ≦ 2), Sn, Y ₂ O ₃ , ZrO ₂ , TiO ₂ , Cr, and the like are particularly preferable because of excellent corrosion resistance.
[0029]
The thickness of the corrosion prevention layer 5 is preferably 5 to 200 mm in view of the corrosion resistance improving effect and cost. If the thickness of the corrosion prevention layer 5 is less than 5 mm, the effect of improving the corrosion resistance of the metal thin film 2 cannot be obtained, and even if it is thicker than 200 mm, the corrosion resistance is not further improved.
By providing such a corrosion prevention layer 5, the corrosion resistance can be further enhanced.
[0030]
The corrosion prevention layer 5 can be provided between the metal thin film 2 and the film 1 as in the example shown in FIG. 2, but may be provided between the metal thin film 2 and the first coating layer 3a. Furthermore, in order to further improve the corrosion resistance, the corrosion prevention layer 5 may be provided both between the metal thin film 2 and the film 1 and between the metal thin film 2 and the first coating layer 3a.
In particular, in the metal-coated yarn manufacturing sheet used for the production of gold and silver yarn, when the corrosion prevention layer 5 is provided between the metal thin film 2 and the film 1, the material of the corrosion prevention layer 5 is ZnO and SnO _x ( However, one or two substances selected from 0 <x ≦ 2) are preferable. Since the corrosion prevention layer 5 formed of these substances has high transparency, the gloss of the metal thin film 2 when viewed from the film 1 side is hardly hindered and a good gloss can be obtained.
[0031]
The metal-coated yarn manufacturing sheet shown in FIG. 3 has an undercoat layer 6 provided between the film 1 and the metal thin film 2. As the material of the undercoat layer 6, the same material as the first and second coating layers 3a and 3b is preferably used. By providing the undercoat layer 6, the bonding strength between the film 1 and the metal thin film 2 can be increased. Moreover, the corrosion resistance of the metal thin film 2 can be further improved.

Moreover, it is good also as a double-sided sheet | seat obtained by preparing two sheets for said metal-coated yarn manufacture, and adhere | attaching them. The two metal-coated yarn manufacturing sheets used for the double-sided sheet may have the same configuration or different configurations.
The metal-coated yarn manufacturing sheet shown in FIG. 5 is a double-sided sheet in which two metal-coated yarn manufacturing sheets shown in FIG. 1 are prepared, these film 1 sides are opposed, and the support layer 8 is sandwiched therebetween. .
[0034]
As the support layer 8, Japanese paper, Western paper, synthetic fiber non-woven fabric or the like can be used, and although the thickness is not limited, a layer of about 5 to 200 μm is preferable. If the thickness of the support layer 8 is less than 5 μm, the reinforcing effect is reduced, and if it exceeds 200 μm, the sheet becomes stiff and difficult to manufacture. Moreover, when the yarn manufactured from this sheet is used for clothes or the like, the touch becomes worse.
As an adhesive for adhering the support layer 8, any conventionally used adhesive such as a vinyl chloride-vinyl acetate copolymer adhesive or an epoxy adhesive may be used.
[0035]
In the metal-coated yarn manufacturing sheet, the coating layer 3 is composed of two layers of the first coating layer 3a and the second coating layer 3b, but may be composed of one layer containing a silane coupling agent. The metal-coated yarn manufacturing sheet may be further provided with one or more coating layers to form three or more layers, and is not particularly limited. When only one layer is used, labor and cost for forming the coating layer can be reduced, and when three or more layers are used, durability can be further improved.
