板１の露出面と向かい合う。 In this way, a heat ray reflective film 2 is placed on a transparent resin plate 1.
The laminated plate 3 with the heat ray reflective film 2 facing downward is attached to the press molding device 4 as shown in FIG. 3. That is, the device 4 includes a male mold 5 whose surface is coated with a mold release agent and has the inner surface shape of the lid to be molded.
is provided on the elevator 6, covers the male die 5 so as to close the upper opening of the housing 7, and supports the peripheral end surface of the overlapping plate 3 by clamp devices 8, 8. Note that 9 is a heater device located above the overlapping plate 3, and faces the exposed surface of the transparent resin plate 1.

る。 With the polymer plate 3 attached to the press molding device 4 in this way, the transparent resin plate 1 faces the heater device 9 and does not face the male mold 5, and the two sides of the heat ray reflective film correspond to the male mold 5. are doing. In the state shown in FIG. 3, the polymer plate 3 is heated by the heater device 9 to soften the transparent resin plate 1 and the heat ray reflective film 2. However, since the adhesive layer 2a on which the heat ray reflective film 2 is attached to the resin plate has a lower melting point than the transparent resin plate 1, it becomes semi-molten by this heating. That is, among the heat rays radiated from the transparent resin plate 1 heated by the heater device 9, the heat rays radiated in the direction of the heat ray reflective film 2 pass through the glue layer 2a, and then are reflected in the direction of the transparent resin plate 1 by the vapor deposition layer 2c. will be reflected.

皺が発生するのを防止することができる。 According to this method, by heating the transparent resin plate 1 from the direction of its exposed surface with the heater device 9, the heat rays radiated from the transparent resin plate 1 in the direction of the heat ray reflective film 2 are reduced. glue layer 2
After passing through a, the light is reflected in the direction of the transparent resin plate 1 by the vapor deposited layer 2c. As a result, after molding, the vapor deposited layer 2c that reflects heat rays such as sunlight can be used to melt the glue layer 2a, so the energization time of the heater device 9 is shortened, and it is easier to move on to the next molding process. It gets faster. Moreover, since the surface of the male die 5 comes into contact with the heat ray reflective film 2 when the polymer plate 3 is pressed,
The heat ray reflective film 2 itself acts as a cushioning material, and no surface traces of the male die 5, that is, a cloudy surface, are formed on the transparent resin plate 1.
The lid 10 can be molded without impairing the transparency of the transparent resin plate 1, and since the glue layer 2a is in a semi-molten state, the transparent resin plate 1 with a high elongation rate is applied to the heat ray reflective film 2 through the glue layer 2a. It is possible to prevent cracks and wrinkles from occurring in the heat ray reflective film 2 due to slipping on the top.

ある。 Therefore, it is possible to easily form the lid 10 having a cubic curved surface that has a high heat insulation effect, a high transparency effect, and a high heat ray reflection effect. The present invention described above consists of a main base layer, a vapor deposited layer provided on the base layer that reflects heat rays such as infrared rays, and an acrylic film on a flat plate made of a thermoplastic transparent resin provided on the vapor deposited layer. A transparent thermoplastic heat-reflecting film, which is adhered to substantially the entire surface of one side of the resin and is composed of a glue layer having a melting point lower than that of the acrylic resin board, is layered on the acrylic resin board via the glue layer. Paste them together and
After the acrylic resin plate is heated from the direction of its exposed surface, a male mold having a predetermined shape is press-molded in correspondence with the heat ray reflective film surface to form the acrylic resin plate into a predetermined shape, so the heating step is not necessary. The vapor deposition layer reflects the heat rays from the resin plate toward the heat ray reflective film toward the resin plate, and the incident and reflection of these heat rays accelerates the melting speed of the glue layer, shortens the heating process time, and allows the next molding process. In addition to being able to be transferred quickly, the heat ray reflective film itself can act as a cushioning material, so it can be formed into a predetermined shape without impairing the transparency of the transparent resin, and the generation of cracks and wrinkles in the heat ray reflective film can be prevented. . This not only shortens the manufacturing time, but also allows the heat ray reflection function of the vapor-deposited layer of the heat ray reflection film to work effectively during the heating process.
It can also be effectively applied to transparent lids or transparent doors that are molded into a predetermined shape and have a good heat ray reflection effect.
