[Industrial Field of Application] The present invention relates to a laminated sheet made by laminating a laminated film with excellent dew condensation prevention performance to various plastic sheet-like materials or plate-like materials such as metal or glass. [Prior Art] Conventionally, acrylic boards, polycarbonate boards, hard vinyl chloride boards, FRP boards, glass boards, etc. are often used for general structural facilities, gardening roof boards, window boards, etc. [Problem to be solved by the invention] However, when these are used as roofing materials for greenhouses for gardening purposes, for example, when there is a large difference between the temperature inside the greenhouse and the outside temperature, condensation occurs inside the greenhouse. This can obstruct the transmission of light rays, or cause condensed water droplets to fall irregularly, causing spots on flowers, fruits, etc. being grown in the greenhouse, or causing roots to grow. Moisture is the cause of disease outbreaks. In order to solve these problems, generally a surfactant suitable for preventing dew condensation is applied to the surface of the various board materials mentioned above as a drop accelerator, or a paint with such properties is applied to the surface. I also apply it. However, in either case, the dew condensation prevention effect disappears in a short period of time and is not sustainable, so the above-mentioned application must be repeated many times, which is not only complicated but also extremely uneconomical. There is a problem that. [Means for Solving the Problems] In view of the above-mentioned problems, the inventors of the present invention have conducted intensive studies to obtain a laminated sheet that can permanently exhibit a dew condensation prevention effect, and as a result, have arrived at the present invention. That is, this invention provides a laminated film that can permanently prevent dew condensation by laminating a film with dew condensation prevention performance obtained by saponifying cellulose triacetate film and a heat-fusible film using a thermosetting resin. The present invention provides a laminated sheet made by laminating a film onto various plastic sheet-like materials by thermal fusion. [Function] To explain in more detail, this invention applies a laminated film obtained by bonding a film with dew condensation prevention performance and a heat-adhesive film to an acrylic board conventionally used as roofing material for general structures and greenhouses. , polycarbonate board, hard vinyl chloride board, FRP board,
It has been discovered that a laminated sheet with excellent dew condensation prevention performance and a long life can be produced at a very low cost by heat-sealing it to a glass plate or the like. The laminated sheet with excellent dew condensation prevention effect obtained in this way can be used not only for roof panels for gardening, but also for window panels for general construction, lens panels for goggles, window panels for cold cases, mirror panels, curved mirrors, etc. By applying thermoforming, it can be widely used. The film having anti-condensation properties obtained by saponifying the cellulose triacetate film used in this invention is prepared by adding 50 to 400 parts by weight of sodium hydroxide or/and potassium hydroxide and 10 to 100 parts by weight of benzine alcohol to water. 1000
5 to 60 parts by weight of cellulose triacetate plastic film was added to the treatment solution at 30 to 90°C.
A film obtained by immersion for a minute and saponification treatment is used. Films with thermal adhesive properties include acrylic, polyvinyl chloride, polyvinyl chloride-vinyl acetate copolymer, polyamide, and polyethylene-based films.
Vinyl acetate-based, polyurethane-based, polyester-based materials with a thickness of 5 to 500 μm and a melting point of 50 to 250° C. are suitable. Furthermore, plastic sheet-like materials laminated with a laminated film consisting of a film with anti-condensation properties and a film with heat-fusibility include acrylic sheets, FRP sheets, hard vinyl chloride sheets,
Polycarbonate sheets, etc. are used, as well as glass plates, metal plates, etc. When a laminated film is obtained by combining a film with anti-condensation properties and a film with heat-adhesive properties, the lamination of both films is made using polyurethane, polyacrylic, polyester, polyimide, epoxy, or acrylic urethane. A thermosetting adhesive such as the like may be used. In addition, in the case where a laminated sheet is obtained from the laminated film obtained as described above and the various sheet-like materials described above, in order to bond the two, heat is applied to melt the surface of the heat-fusible film surface of the laminated film and bond the laminated film together. Fusion method is suitable. [Example] Hereinafter, the present invention will be explained in detail with reference to Examples. Example 1 150 parts by weight of sodium hydroxide, potassium hydroxide
150 parts by weight, 30 parts by weight of benzine alcohol, water
An anti-condensation film obtained by immersing a cellulose triacetate film with a thickness of 50μ for 45 minutes in a treatment solution at 50℃ prepared by mixing 1000 parts by weight with a heat-sealable film having a thickness of 35μ and a melting point of 120℃ An acrylic film was bonded to the film using a thermosetting polyester adhesive to obtain a laminated film. This laminated film was molded onto a polycarbonate sheet obtained by extrusion molding and then bonded by heat fusion to obtain a laminated sheet with excellent dew condensation prevention properties. When the thus obtained laminated sheet was tested for its dew-preventing performance, the results shown in Table 1 below were obtained, and the polycarbonate sheet tested as a comparative product, the surface of which was coated with a dew-preventing agent, and the polycarbonate sheet that was not subjected to any treatment. It was recognized that it was extremely superior to polycarbonate sheets. In addition, the breath test is about 5% of the test piece at room temperature.
The surface condition of the test piece was determined by blowing on it from a distance of ~10 cm.

[Table] Example 2 An anti-condensation film obtained by saponifying a cellulose triacetate film with a thickness of 25 μm in the same manner as in Example 1 and a heat-fusible polyvinyl chloride film with a thickness of 30 μm and a melting point of 90° C. They were bonded together using a thermosetting polyurethane adhesive to obtain a laminated film. This laminated film was heat-sealed to a polyvinyl chloride sheet obtained by extrusion molding, and then hot press-molded onto a polyvinyl chloride corrugated sheet to obtain a dew-preventing polyvinyl chloride corrugated sheet. Place the corrugated plate thus obtained on the top of the steam generator box for 30 minutes.
When using the corrugated plate as a lid material at an angle of 100 degrees, steam was continuously generated, and the state of dew condensation on the corrugated sheet material as a lid material was observed after the required time had elapsed.
The results shown in the table were obtained, and even when steam was applied to the corrugated sheet for 24 hours continuously, there was no sign of dew condensation at all, and it was confirmed that it had a significant dew condensation prevention effect compared to the test results of the corrugated sheet as a comparison product. It was done.
