Description

[Detailed Description of the Invention] This invention relates to a laminated plate used as a sealing plate, a name plate, etc.

Name plates are attached to the cases of various electrical devices to explain how to use them and to provide decoration.

Some name plates of this type are half-cut and placed on a release paper at predetermined intervals, and are sold and transported in this state.

However, conventional nameplates are formed by depositing an aluminum film on a plastic sheet or bonding a soft aluminum thin plate.

Because of this, the conventional plastic sheeting is 0.05 to 0.
In the case of an aluminum layer with a thickness of 0.09 mm, the name plate and the scraps could not be separated using a half-blanking press.
It is often delivered half-opened.

Also, due to the difference in elasticity, water resistance and mechanical strength between the plastic layer and the aluminum layer, this nameplate can be used when exposed to hot water or cold temperatures in winter after being attached to the device. However, the plate has the disadvantage that each layer may separate or warp.

In addition, when half-cutting this type of nameplate, the plastic sheet and aluminum film are cut at the same time, so the difference in shear strength between the two may cause the cut portion to peel off, or the cut surface may become rough, causing it to stick to the equipment. After that, it will easily peel off due to external force.

This invention was proposed to improve the above-mentioned problems regarding laminated plates.

Therefore, the purpose of this invention is to provide laminated plates that are arranged separately and have excellent adhesion to various devices and are aesthetically pleasing by having the periphery of each laminated plate slope gently from above to below. be.

Next, this invention will be explained based on the drawings. FIG. 1 shows a laminated plate 2 according to this invention.

Each laminated plate 2 consists of a printed layer 4 located on the front surface, a relatively thick aluminum layer 6, and an adhesive layer 8 located on the back surface, and a removable protection layer is provided on the printed layer 4 as desired. A film layer 10 is provided.

Further, each laminated plate 2 is arranged on the release film 12 at a predetermined interval, and the planar shape of the plate can be determined to be circular, rectangular, or other specific shape.

Further, the periphery of each laminated plate 2 is gently sloped from the top to the bottom as shown in the figure, and this slope angle can be determined arbitrarily depending on the thickness and hardness of the aluminum layer 6 or the cutting edge angle of the punching blade type. I can do it.

The aluminum layer 6 is made of a hard or semi-hard aluminum plate, an alumite dyed plate, or another aluminum alloy plate.

The thickness of the aluminum layer 6 is preferably 0.05 to 0.35 mm, and if the thickness is less than 0.05 mm, warping or bending is likely to occur during half-blanking, and the mechanical strength as a name plate is also low.

In addition, if the thickness is 0.35 mm or more, a convexity is likely to occur during the half-blanking process, making it difficult to perform the half-blanking process.

The printing layer 4 is formed by applying an aluminum layer 6 before bonding the adhesive layer 8.
After surface treatment of the aluminum plate as desired, the aluminum plate is formed.

The printed layer 4 may be composed of a large number of printed layers by various printing methods such as alumite printing and offset printing.
It is also possible to carry out baking after the formation of each printed layer.

Further, when the printed layer 4 is applied to the entire surface of the aluminum plate, the printed layer is transferred to the cut surface of the aluminum layer 6 due to the elongation of the aluminum during the half punching process as shown in the figure.

This amount of transfer is approximately 65 to 80% of the thickness of the aluminum layer 6.
%, the ground color of aluminum is almost invisible on the cut surface of the obtained laminated plate 2, which is favorable for the aesthetic appearance of the cross section.

The protective film layer 10 is attached to protect the surface of the printed layer 4.

This protective film layer 10 does not serve as a finish for the printed surface like the surface film of conventional sealing plates, but when the laminated plate 2 is used as a name plate, it can be completely and easily peeled off before and after use. I can do it.

Examples of the protective film layer 10 include Polylamp (manufactured by Ube Industries, Ltd.), which is made by adding a polyhydric alcohol fatty acid ester to polyethylene, or polyvinylidene chloride with epoxidized vegetable oil as a stabilizer and a polybasic fatty acid derivative as a softener. There are products such as Frerap (manufactured by Guju Kagaku Kogyo Co., Ltd.) that contain added .

The adhesive layer 8 is bonded together with the release film 12 to the back surface of the aluminum plate.

The adhesive layer 8 may be a pressure-sensitive double-sided adhesive tape or may be provided using the primary adhesive strength of a pressure-sensitive or heat-sensitive adhesive tape, and the adhesive layer is formed by applying or spraying an adhesive. You may.

The release film 12 may be either a release paper such as kraft glassine paper or a synthetic resin film such as polypropylene treated with silicone and coated with a release agent.

Unlike conventional seal plates, the laminated plate of this invention is manufactured by processing each layer, for example, from the laminated material 14 shown in FIG.

The laminated material 14 has an aluminum plate 16, and the surface of the aluminum plate is hairline-processed, and then heated at 55°C at 65°C.
% caustic soda solution for 3□□□, then washed with water and dried.

Next, after varnishing, it is dried at 165° C. for 12 minutes, offset printed and baked at 165° C. for 2 minutes, and after top coating, it is baked again at 170° C. for 20 minutes to form the printed layer 18.

During this printing, positioning portions (not shown) are simultaneously printed at two locations around the aluminum plate 16.

A protective film layer 20 made of polyethylene is laminated on the surface of the printed layer 18, and then an adhesive layer 22 of double-sided adhesive tape (for example, pressure-sensitive adhesive 203 manufactured by Sony Chemical) is applied to the entire back surface of the aluminum plate 16. is adhered together with release paper 24.

Also, before performing the half-blanking process, a positioning portion is punched.

For half-blanking the laminated material 14, for example, a press die 26 shown in FIG. 3 is used.

This press mold 26 is placed and fixed on the bed 27 of an appropriate flat plate press.

A large number of annular punching blade molds 28 corresponding to the planar shape of the laminated plate 2 are installed on the base of the press mold 26.

As shown in FIG. 4, the punching blade die 28 is made of steel band and has a cutting edge at its upper end, and is a so-called Thomson cutter.

A presser member 30 is housed inside each punching blade die 28, and a cushion member 32 is housed below the presser member.

Furthermore, two positioning pins 34 are installed around the base of the press mold 26, and the pins are vertically expandable and retractable.

The laminated material 14 is set upside down on the press die 26, and at this time the positioning holes are fitted with the positioning pins 34, respectively.

This setting allows the laminated material 14 to be maintained! The film 20 contacts the upper surface of the pressing member 30.

Next, a slider (not shown) of the press is lowered to press the laminated material 14.

At this time, the slider does not come into contact with the cutting edge of the punching blade die 28, and the lower end surface of the slider and the cutting edge are connected to the release paper 28.
The spacing is equal to or less than the thickness of 4.

By this half-cutting process, the protective film 20, the printed layer 18, the aluminum plate 16, and the adhesive layer 22 are punched out of the laminated material 14, leaving the release paper 24 behind.

After this, by removing the scraps, a laminated plate 2 shown in FIG. 1 is obtained.

The laminated plate according to this invention can be used as a name plate or a sealing plate, and as long as the release film is bent, each laminated plate can be quickly peeled off and attached to various devices with ease.

The periphery of this laminated plate is gently sloped from the top to the bottom, so when it is attached to a device, the edge of the laminated plate is less likely to get caught on other objects and peel off, and the name plate is Perfect adhesion can be expected.

Furthermore, if the periphery is gently sloped, even if the surface of the laminated plate is touched by hand, there is no risk of injury to the hand.

Therefore, this laminated plate is suitable as a name plate for household electrical appliances that are often touched by hands, such as portable radios and hair dryers.

Furthermore, the gently sloping periphery of this laminated plate prevents dust from adhering to and accumulating on the edges, so it can be used as a sealing plate or name plate for kitchen utensils that require cleanliness. preferable.

In the laminated plate of this invention, it is possible to almost hide the ground color of the aluminum on the cut surface with the printing layer, so it can be adhesive for a long time even in environments where aluminum is easily corroded, and it is also aesthetically pleasing. be.

Since this laminated plate is made of aluminum alone, it has superior heat resistance, water resistance, and mechanical strength compared to conventional multilayer plates consisting of a plastic layer and an aluminum layer.

Moreover, since the periphery of each plate is inclined when this laminated plate is half-blanked while leaving the release film, there is an advantage that only the blanks can be easily removed from the film compared to the conventional method.
