成型品を効率よく得ることができる紫外線硬化型
のFRPシートに関する。[Detailed description of the invention] (Field of industrial application) The present invention is an ultraviolet curing type that can efficiently obtain glass fiber-containing unsaturated polyester resin molded products by curing it by irradiating it with ultraviolet rays. Regarding FRP sheets.

が開発された。(Prior art) Recently, as a new type of molding material, two colorless sheets are used to cover both sides of an uncured glass fiber-containing unsaturated polyester resin layer (hereinafter referred to as FRP layer) that can be cured by ultraviolet irradiation. A UV-curable FRP sheet coated with a transparent polyvinyl alcohol resin film (hereinafter referred to as PVA film) has been developed.

すると、FRP層が速やかに硬化して目的とする
成型品を得ることができる便利なものであるが、
次のような問題がある。 This sheet is convenient because it can be molded into a desired shape using a vacuum forming machine, for example, and then irradiated with ultraviolet rays in that state, the FRP layer will quickly harden and the desired molded product can be obtained. but,
There are the following problems.
（考案が解決しようとする問題点）
即ち、かかる紫外線硬化型FRPシートを着色

線透過性が低下して硬化に時間がかかるので、

ることが考えられる。(Problems to be solved by the invention) That is, when coloring such an ultraviolet curable FRP sheet, if the FRP layer contains a coloring agent, the ultraviolet transmittance decreases and curing takes time.
It is conceivable that one of the two PVA films covering both sides of the FRP layer is a colored PVA film containing a colorant.

る。 Colored PVA on either side of the FRP layer like this
The FRP sheet covered with a film and the opposite side covered with a transparent PVA film is molded using a vacuum forming machine 100 or the like, with the colored PVA film 101 on the outer surface and the transparent PVA film 102 on the inner surface, as shown in FIG. The ultraviolet irradiation device 103
The ultraviolet rays are passed through the transparent PVA film 102.
By irradiating and curing the FRP layer 104,
The purpose is to obtain a molded product with a colored outer surface.
If the target molded product has a small internal volume, such as a rain gutter with a U-shaped cross section as shown in the figure, the ultraviolet irradiation device 103 cannot be placed inside the mold, so 103 has no choice but to be placed above. Therefore, the distance from the ultraviolet lamp 103a to the FRP sheet is
It varies in each part of the sheet, and the FRP layer is 10
4 becomes difficult to uniformly cure.

成型品を得ることは不可能である。 In addition, even if a molded product is obtained by molding and curing as described above, the PVA film itself has poor adhesion to the FRP layer, so the FRP will be removed by curing.
Colored PVA when layer 104 loses its adhesive strength.
Both the film 101 and the transparent PVA film 102 have the disadvantage of being easily peeled off, and therefore, it is actually impossible to obtain a molded product with a colored outer surface without the risk of the colored PVA film peeling off.
本考案はかかる問題を解決すべくなされたもの
である。 The present invention has been made to solve this problem.

するものである。(Means for Solving the Problems) That is, in the UV-curable FRP sheet according to the present invention, one side of the glass fiber-containing unsaturated polyester resin layer is partially covered with a peelable UV-impermeable film, and , the entire opposite side of the resin layer is coated with a colored opaque film that is non-removable and impermeable to ultraviolet light;
The gist is that the portion covered with the ultraviolet opaque film is an uncured portion that has not yet been cured, and the other portion is a cured portion that has been cured by exposure to ultraviolet rays.

得ることができるのである。(Operations and Effects) If an ultraviolet curable FRP sheet with such a configuration is obtained, the uncured portion of the FRP layer is bent and molded so that the colored opaque film is on the outer surface, and the inner ultraviolet opaque film is peeled off and removed. The desired external colored molded product can be obtained by simply irradiating the uncured area with UV rays and curing them. It becomes unnecessary to intentionally place an ultraviolet irradiation device inside the mold. Therefore, even if the ultraviolet ray irradiation device does not enter the mold, if the ultraviolet rays from the ultraviolet irradiation device placed above are focused in a bundle or band and irradiated only on the uncured portions, and cured to the same extent as the cured portions, A uniformly cured molded product can be obtained without any problems.
しかも、得られた成型品の外面を覆う有色不透
明膜は剥離困難なものであるから、この有色不透
明膜の剥離による脱色の虞も解消されるのであ

ことができるので非常に便利である。 In addition, in this FRP sheet, one side of the uncured part of the FRP layer is covered with a UV-impermeable film, and the entire other side is covered with a colored opaque film that is UV-impermeable, so the UV-impermeable film cannot be peeled off and removed. Unless the uncured portion is exposed to sunlight containing ultraviolet rays, it will not naturally harden. Therefore, unlike conventional FRP sheets, it is not necessary to store and transport the sheet in an ultraviolet blocking packaging bag or the like, and it can be stored and transported naked, which is very convenient.

One side of the FRP layer 1 is covered with a UV-transmissive film 2 and a removable UV-impermeable film 3 which are arranged in alternation, and the other side is covered with a non-removable UV-impermeable colored opaque film 4. is completely covered with. Then, the part where one side of the FRP layer 1 is covered with the ultraviolet opaque film 3 becomes an uncured part 12 which has not yet been cured, and the part covered with the ultraviolet transmissive film 2 becomes a hardened part 11 which has been cured by exposure to ultraviolet rays. ing.

However, it is easily manufactured by irradiating ultraviolet rays from one side, and only the part that is irradiated with ultraviolet rays through the ultraviolet transmitting film 2 is cured to become a hardened part 11, and the ultraviolet rays are not exposed to the ultraviolet rays in the ultraviolet opaque film 3. The blocked portion is not cured and becomes an uncured portion 12.

The FRP layer etc. are partially cured as described above. During this partial hardening, flat plate-like
Since the FRP layer 1 only needs to be irradiated with ultraviolet rays, it can be cured extremely easily. The uncured portion 12 of the FRP layer 1 is soft and deformable, and the surface is sticky and sticky, but the cured portion 11 partially cured by ultraviolet irradiation as described above is tough. And it's not sticky either.

望ましい。 Both the ultraviolet-transmissive film 2 and the ultraviolet-opaque film 3 are adhered and laminated using the adhesiveness of the surface of the FRP layer 1 before partially curing the FRP layer 1 as described above. The permeable membrane 2 is uncured.
Since it is provided to eliminate the stickiness of the FRP layer 1 and improve its handling, all kinds of conventional transparent synthetic resin films (colorless transparent or colored transparent) that can transmit ultraviolet rays can be used. Furthermore, it may be one that adheres to the cured portion 11 or one that peels off as the FRP layer 1 partially cures. In addition, when using a releasable transparent synthetic resin film such as a polyvinyl alcohol resin film as the ultraviolet transmitting film 2, the film is immediately peeled off after the FRP layer 1 is partially cured, and the cured portion 11 is exposed. However, if exposed in this way, the cured portion 11 may turn yellow due to sunlight, etc., and the glass fibers may come out to the surface.
For example, acrylic resin film, polyvinyl chloride resin film, fluororesin film, polycarbonate resin film, polystyrene resin film,
It is desirable to cover and protect one side of the cured portion 11 using a transparent synthetic resin film having adhesive properties such as a polyester resin film or a cellophane film.

Various colored and opaque synthetic resin films, chemical paper, single-sided adhesive silver paper, and the like are used, which contain a large amount of pigment and are colored and opaque so that they can block about 90% or more of ultraviolet rays. Since the ultraviolet opaque film 3 is adhered and laminated by the adhesiveness of the uncured portion 12 as described above, it can be peeled off freely.

It is necessary that the material cannot be peeled off. Examples of such colored opaque film 4 include acrylic resin film, polyvinyl chloride resin film, fluororesin film, polycarbonate resin film, polystyrene resin film, which is made colored and opaque by mixing a large amount of coloring agents such as pigments and dyes. Synthetic resin films having adhesive properties such as polyester resin films and cellophane films, colored opaque chemical paper, and single-sided adhesive silver paper are used. Of course, the above-mentioned synthetic resin films and chemical papers colored with two or more colors to form patterns are also preferably used.

硬化部１２とを得ることができる。 In this embodiment, the ultraviolet-transmissive film 2 and the ultraviolet-impermeable film 3 are laminated alternately in parallel on one side of the FRP layer 1, but for example, one film may partially contain pigment. The pigment-containing portion may be configured to be a UV-impermeable film and the pigment-free portion may be a UV-transmissive film, and this film may be laminated on one side of the FRP layer 1. If you do it like this
The effort of laminating the film on one side of the FRP layer 1 is only required once, and the cured portion 11 and the uncured portion 12 can be obtained extremely easily by ultraviolet irradiation.

る。 For example, as shown in Fig. 3, an ultraviolet curable FRP sheet having the above-mentioned structure can be produced using a vacuum forming machine 5.
etc., so that the colored opaque film 4 becomes the outer surface.
The uncured part 12 of the FRP layer 1 is bent and molded,
By peeling and removing the ultraviolet opaque film 3 on the inner surface and irradiating the uncured part 12 with ultraviolet rays from the ultraviolet irradiation device 6 and curing it, the desired outer surface colored molded product (in the example shown, a U-shaped cross section) is produced. gutter). In this case, the ultraviolet irradiation device should be 365~
A device that emits ultraviolet light with a wavelength of 400 nm is preferably used, and the irradiation time is such that the thickness of the uncured part is 5 to 500 nm.
If the diameter is 6 mm or less, a few minutes is sufficient. Also,
As the molding machine, in addition to the illustrated vacuum molding machine 5, a pressure molding machine, a press molding machine, etc. can also be used.

る。 In the example shown in FIG. 3, the ultraviolet ray irradiation device 6 is provided with irradiation ports 61, 61, and the ultraviolet rays are concentrated into a bundle or band shape and irradiated only to the uncured portion 12. If you do not set
It is desirable to cover the cured portion 11 with an ultraviolet blocking plate or the like so that only the uncured portion 12 is irradiated with ultraviolet rays. This is because if the cured portion 11 is also irradiated with ultraviolet rays, there is a risk that the cured portion 11 will deteriorate.

ることができるのである。 In this way, in the FRP sheet of the present invention, only the uncured portion 12 needs to be cured by UV irradiation, and unlike conventional FRP sheets, it is not necessary to cure the entire FRP layer at once by UV irradiation. Therefore, it is not necessary to intentionally arrange the ultraviolet irradiation device 6 in the mold of the molding machine 5 for uniformly irradiating the entire FRP layer 1 with ultraviolet rays. Therefore,
Even if the target molded product is small, like the rain gutter shown in the example, and the UV irradiation device cannot be inserted into the mold, the UV irradiation device 6 placed above can be used.
The uncured portion 1 is concentrated by concentrating ultraviolet rays into a bundle or band shape.
By irradiating only the cured portion 2 and curing it to the same extent as the cured portion 11, a uniformly cured molded product can be obtained without any problems.
しかも、得られた成型品の外面を覆う有色不透
明膜４はFRP層１と接着し、剥離困難なもので
あるから、この有色不透明膜４の剥離による脱色
の虞も解消されるのである。 Moreover, since the colored opaque film 4 covering the outer surface of the obtained molded product adheres to the FRP layer 1 and is difficult to peel off, the fear of decolorization due to peeling of the colored opaque film 4 is eliminated.
また、FRP層１の未硬化部１２の片面が紫外

る。 In addition, if one side of the uncured portion 12 of the FRP layer 1 is covered with the ultraviolet opaque film 3 and the entire other side is covered with a colored opaque film 4 that is impermeable to ultraviolet rays, the ultraviolet opaque film 3 can be peeled off and removed. Unless otherwise, the uncured portion 12
Since it does not naturally harden when exposed to sunlight containing ultraviolet rays, there is no need to store and transport it in a UV-blocking packaging bag like conventional FRP sheets, and store and transport it as it is. There is also the convenience of being able to do so.

する利点がある。 In the FRP sheet of the embodiment shown in FIG. 1 as described above, the uncured portion 12 of the FRP layer 1 is exposed after curing and is likely to deteriorate.In order to prevent this, the FRP sheet of the embodiment shown in FIG. It is desirable that one side of the FRP layer 1 is entirely covered with an ultraviolet-transparent film 2 having adhesive properties, and only the portion remaining as an uncured portion 12 is further covered with an ultraviolet-impermeable film 3. With this configuration, the molded product obtained by peeling off the UV-impermeable film 3 and curing the uncured portion 12 by UV irradiation has the UV-transparent film 2 and the colored opaque film 4 on both its inner and outer surfaces. coated and protected
Since the FRP layer 1 is no longer exposed, there is an advantage that weather resistance is improved.
