The protective sheet 11 which is an acrylic resin sheet having a thickness of about 0.12 mm is adhered to the surface of the laminated sheet 1 to form the laminated sheet 1 having excellent weather resistance. In addition to the polycarbonate resin sheet, the resin sheet 10 may be a transparent plastic sheet such as an acrylic resin sheet or a vinyl chloride resin sheet.

The back layer 35 has a thickness of about 0.08 mm,
Although the acrylic resin sheet is colored in advance, a sheet in which characters, patterns, and the like are applied to the surface of the acrylic resin sheet by printing or the like may be used. The back layer 35 may be an ABS resin sheet, an olefin resin sheet, a vinyl chloride resin sheet, or the like. Reference numeral 32 denotes a masking layer, which is a film having a weak adhesiveness and a thickness of about 0.05 mm, which is attached to a region of the resin sheet 10 where the see-through window is to be formed and the surface of the border layer 30. The masking layer 32 is formed of the resin sheet 10
It is a resin-impregnated paper or a polyethylene masking film that can seal an adhesive and a solvent for attaching the back layer 35 to the base material and has good releasability.

Reference numeral 40 denotes a carrier plate, which is a resin sheet 10
In the step of attaching the back layer 35 to the resin sheet 10, the resin sheet 10 is conveyed between the pair of upper and lower pressure rollers 41 and 42. The feed rollers 41 and 42 are provided on the back layer 3.
5 is supplied onto the resin sheet 10 on the carrier plate 40.

Reference numeral 50 denotes a molding die, which is a die for molding the laminated sheet 1, and has a concave heat-resistant rubber 55 on the upper surface. The mold 50 and the heat-resistant rubber 55 are provided with an injection port 52 for sending air in a direction indicated by an arrow in FIG. Further, the mold 50 is provided with a plurality of suction ports 51 for sucking air in a direction indicated by an arrow in FIG. The heat-resistant rubber 55 is made of heat-resistant silicon rubber,
The outer peripheral length of the heat-resistant rubber 55 is equal to or slightly larger than the outer peripheral length of the see-through window 20. Reference numeral 65 denotes a heater, which is planar and horizontally disposed above the mold 50. Reference numeral 60 denotes a clamp frame, which horizontally fixes the laminated sheet 1 between the mold 50 and the heater 65.
When the mold 50 rises while the laminated sheet 1 is fixed by the crank frame 60, the heat-resistant rubber 55 comes into contact with the laminated sheet 1. At this time, the crank frame 60 and the molding die 50 are arranged at positions where the heat-resistant rubber 55 is in close contact with the periphery of the see-through window 20.

A method for manufacturing the laminated sheet of this embodiment will be described. First, as shown in FIG. 1, a protective sheet 11 is attached to one surface of a resin sheet 10 in advance. Next, as shown in FIG. 2, a border layer 30 is provided by silk printing on a surface of the resin sheet 10 having no protective sheet 11 around a region where the see-through window 20 is to be formed. Edge layer 3 at this time
The thickness of 0 is about 0.02-0.05 mm. The edging layer 30 may be formed by spray coating, or the edging layer 30 may be formed by sticking a seal.

Subsequently, as shown in FIG. 3, the masking layer 32 is placed on the resin sheet 10 inside the edge layer 30 so that the end of the mask layer 32 runs over the edge layer 30.
Stick it. Note that the masking layer 32 used is cut into a predetermined size in advance. Also, the masking layer 32
When sticking, it is necessary to take care not to wrinkle in order to enhance the sealing effect of the masking layer 32.

Next, as shown in FIG.
Is placed on the carrier plate 40 with the side to which the masking layer 32 is attached facing up. Then, while applying an adhesive or a solvent in the direction of arrow A, the resin sheet 10
And the back layer 35 fed by the feed rollers 43 and 44 are adhered and laminated by being sandwiched between a pair of upper and lower pressing rollers 41 and 42 rotating in the direction of arrow B. At this time, the pressure roller 41 on the back layer 35 side is heated to about 50 to 80 ° C. Although a pre-colored acrylic resin sheet is used for the back layer 35 of the present embodiment, when a character or pattern is applied to the surface of the acrylic resin sheet by printing or the like, printing is performed. If it is arranged between the resin sheet 10 and the back layer 35, characters and patterns can be protected.

When the resin sheet 10 is a polycarbonate resin sheet and the back layer 35 is an acrylic resin sheet, they are bonded and laminated using an acrylic adhesive. Similarly, as the solvent, a solvent capable of dissolving both the polycarbonate resin and the acrylic resin, for example, ethyl acetate, methyl ethyl ketone, or the like can be used.

The laminated sheet 1 is placed in a heating and drying oven and subjected to an annealing treatment. In this treatment, the laminated sheet 1 is heated and dried at a temperature of 50 to 80 ° C. for 5 to 20 hours, whereby the residual solvent of the laminated sheet 1 is removed, and the distance between the resin sheet 10 and the back layer 35 is reduced. The adhesive strength is increased, and moisture remaining in the resin sheet 10 is removed.

Laminated sheet 1 after annealing
Cuts the back layer 35 at the position indicated by the alternate long and short dash line shown in FIG. Then, by removing the back layer 35 and the masking layer 32 around the see-through window 20 in the direction of arrow E in FIG. 6, the see-through window 20 as shown in FIG. 7 is formed. By setting the position where the back layer 35 is cut above the edge layer 30, the resin sheet 10 is protected by the edge layer 30, and the resin sheet 10 is not damaged by the blade of the cutter. There is no problem if the back layer 35 of the laminated sheet 1 cooled after the annealing is cut, but it is better to cut the laminated sheet 1 in a warm state immediately after the annealing because the back layer 35 has flexibility. Therefore, it is possible to cut smoothly, and it is easy to peel off the masking layer 32.

According to the manufacturing method as described above, the transparent window 2
0 can be obtained, but according to the manufacturing method of the present embodiment, the back layer 35
Is applied, a part of the back layer 35 and the masking layer 32
Is removed to form the see-through window 20. That is, after the heating for attaching the back layer 35 to the resin sheet 10 is completed, the see-through window 20 is completed, so that the see-through window 20 itself is not deformed by heat, and the see-through window 20 having the same shape is not deformed. Can be efficiently manufactured with a reduced yield.

Further, the masking layer 32 is previously formed on the border layer 3.
The end of the masking layer 32 is stuck on the inner resin sheet 10 so as to ride on the border layer 30. For this reason, the adhesive or the solvent for bonding the resin sheet 10 and the back layer 35 does not adhere to the see-through window 20, and the laminated sheet 1 having the see-through window 20 having high see-through property can be obtained. Since the adhesiveness of the masking layer 32 is weak,
The separation from the resin sheet 10 is easy, and no stain is left on the resin sheet 10.

A method for forming a laminated sheet according to this embodiment will be described. First, as shown in FIG. 8, the laminated sheet 1 is supported by the crank frame 60, and the laminated sheet 1 is
Heat to 140 ° C. If the temperature is too low, the softening becomes insufficient, and if it is too high, the softening becomes excessive and the workability deteriorates.

Next, air is discharged from the injection port 52 in the direction of arrow nu in FIG.
The mold 50 is lifted in the direction of arrow R while sucking the air between 0 and the direction of the arrow through the suction port 51. Then, as shown in FIG. 10 and FIG.
However, when it comes into close contact with the heat-resistant rubber 55, the discharge of the intake air from the inlet 52 is stopped, and the inlet 52 is closed to prevent air from leaking from the inlet 52. When the laminated sheet 1 comes into close contact with the heat-resistant rubber 55, the laminated sheet 1
An air reservoir 58 is formed between the heat-resistant rubber 55 and the heat-resistant rubber 55. Since the inside of the air pool 58 is filled with air and the pressure is increased, the see-through window 20 hangs down and does not touch the heat-resistant rubber 55.

Subsequently, the mold 50 is raised, and the laminated sheet 1 is brought into close contact with the mold 50 as shown in FIG.
Since the air between the laminated sheet 1 and the molding die 50 is sucked in the direction of the arrow by the suction port 51, the laminated sheet 1 is vacuum-formed by the molding die 50. After the laminated sheet 1 is cooled, the mold 50 is removed, and cut by a dashed line に お け る in FIG.
The forming of the laminated sheet 1 ends. In addition, if the laminated sheet 1 of the present embodiment is formed by using the forming method of the present embodiment, a portion, such as a spear tire cover and a license plate cover, mounted on the rear portion of the automobile, for protecting a portion to be viewed inside is protected. It is possible to manufacture a cover or a cover capable of emitting light from the inside to the outside, such as a cover or a hog lamp cover.

According to the molding method in the embodiment of the present invention, the air pool 5 is placed between the laminated sheet 1 and the heat-resistant rubber 55.
Since the projection 8 is provided, the see-through window 20 does not directly contact the molding die 50 in the molding process. For this reason, the resin sheet 10 in the heated and softened transparent window 20 portion does not stay in contact with the molding die 50, and maintains the high transparency while maintaining high transparency.
0 can be formed. Further, since the heat-resistant rubber 55 is used as the concave material provided in the molding die 50, the heat-resistant rubber 55 can be in close contact with the laminated sheet 1 without any gap due to the elasticity of the rubber, and the air pool 58 can be sufficiently sealed. It becomes possible.

The laminated sheet 1 of this embodiment is a resin sheet 1
Since polycarbonate is used as 0, it is resistant to impact, and is excellent in weather resistance by sticking the protective sheet 11 made of an acrylic resin.

Forming a window. In other words, after the heating step in the manufacturing process, the see-through window is completed,
The see-through window itself is not deformed by heat, and a laminated sheet having the same shape see-through window can be manufactured. As a result,
It can be manufactured efficiently with good yield. Also,
After a masking layer in the form of a film having low adhesiveness is adhered to a region of the resin sheet where the see-through window is to be formed and the surface of the border layer, a back layer is adhered to the resin sheet. That is, since the back layer is attached to the resin sheet via the masking layer, the adhesive or solvent for bonding the resin sheet and the back layer does not adhere to the see-through window, and the masking is not performed. Since the layer can be removed without contaminating the resin sheet, a laminated sheet having a transparent window with high transparency can be obtained.

According to the eighth and ninth aspects of the present invention, since polycarbonate is used as the resin sheet, the resin sheet is resistant to impact, and furthermore, the protective sheet made of an acrylic resin is adhered to provide weather resistance. Also excellent in nature.
