Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an adhesive material that is applied when painting objects such as automobiles and motorcycles, and that gives a predetermined decoration to the surface of the object. .

(Prior Art) Conventionally, decorative adhesives have been used as decorative adhesives for pasting accent stripes on the painted surfaces of objects to be painted, such as automobiles and motorcycle bodies. It is known that a masking material is removably attached to the upper surface of the main body.

(Problems to be Solved by the Invention) The above decorative adhesive material may be used, for example, as follows. That is, after forming the undercoat film b and the intermediate coat c on the surface of the vehicle body a as shown in the first figure,
In applying the top coat, after the decorative adhesive material D is applied, a top coat is applied to the intermediate coating film c, including the entire upper surface of the adhesive material D, to form a top coat e. After that, as shown in the second figure after heating and drying, by removing the masking material f on the upper surface of the adhesive material body d, a decorative surface is formed by the decorative adhesive material body d with the decorative surface exposed on the outer surface. Get a painted car body. However, in practice, when the masking material f is peeled off and removed, the upper surface of the decorative adhesive material D is covered with the top coat e, so it is difficult to confirm its location, and in particular, the masking material It is impossible to confirm the location of the periphery of the masking material f, and it is extremely difficult and time consuming to insert tweezers or fingers through the top coat e and pinch the periphery of the masking material f to remove it. However, during the removal process, the painted surface and peripheral edge of the decorative adhesive material body d are often damaged with tweezers or fingers.
This causes a decrease in productivity, and furthermore, rainwater enters between the peripheral side of the main body d and the inner peripheral surface of the coating film e on its outer periphery, or rainwater and paint components enter the back surface from the peripheral edge of the main body d. This causes problems such as a decrease in the adhesive strength of the adhesive.

(Means for Solving the Problems) The present invention solves the above-mentioned conventional disadvantages and provides an adhesive for decorating a painted object that can obtain a painted surface with a decorative display without damaging the painted surface. In the adhesive material for decoration of a coated object, which is made of a masking material removably adhered to the upper surface of the decorative adhesive material body,
The masking material is made of a heat-shrinkable material.

(Example) Next, an example of the present invention will be described with reference to FIG.
In the drawings, reference numeral 1 indicates a tape made of vinyl chloride, polyester, etc., which has an adhesive layer 2 on the back side and a printed display 3 consisting of letters, designs, or patterns alone or in combination on the front side, and has a predetermined shape such as a tape shape or a rectangular shape like a label. A heat-resistant decorative adhesive body made of synthetic resin, metal foil, etc. is shown, and a heat-shrinkable masking material 4, for example, a heat-shrinkable PVC film material 4, is coated with an acrylic adhesive on the top surface of the adhesive body 1. The adhesive material A for decorating objects to be coated of the present invention was constructed by pasting through layer 5. The heat-shrinkable synthetic resin film is not limited to vinyl chloride, and any conventionally known film such as heat-shrinkable polypropylene can be used. It is preferable that the adhesive 5 applied to the back side has a weak adhesive force that is weaker than the heat shrinkage force of the heat-shrinkable masking material 4. 6 shows a release paper that is peeled off during use.

The above-mentioned adhesive material A for decoration of a coated object of the present invention is applied to a coated object B.
For example, an example of use in a car body painting process will be explained. FIG. 4 shows that after an undercoat film 7 and an intermediate coat film 8 are sequentially formed on the B side of the vehicle body by a conventional method,
A state in which the adhesive material A of the present invention is adhered and a top coat 9 is formed on the entire upper surface thereof is shown. When this state is placed in a heating furnace and heated for 20 minutes at 150°C, the masking material 4 on the top surface of the adhesive material body 1 shrinks due to heat, as shown in Figure 5, and the top coating covering the outer periphery of the adhesive material body 1 shrinks as shown in the figure. While curling with the coating film part 9',
The lower surface of the masking material peels off from the upper surface of the adhesive material body 1 and is automatically dropped and removed. Alternatively, the curled masking material can be easily removed with fingers, etc., and the decorative surface of the adhesive material body 1 can be easily and quickly removed. A painted vehicle body exposed to the outside is obtained.

FIG. 6 shows that when the adhesive material A of the present invention is applied directly to the object B and the object B is painted, the paint is
An example of use is shown in which a coating film 10 is applied and formed on the entire upper surface of the adhesive material A, excluding the center part and the entire upper surface of the peripheral part. Similar to the usage example, the masking material 4
Due to heat shrinkage, the masking material 4 is automatically curled and peeled off from the periphery along with the coating film 10' on the upper surface, while the peripheral surface of the adhesive base body 1 and the peripheral inner surface of the coating film 10 on the outer periphery are A bonding interface with sufficient adhesion is obtained, thus preventing rainwater from entering through this interface, and preventing rainwater from entering the back side of the adhesive material body 1, causing metal corrosion of the peeled coating material of the body 1. A coated object with a decorative surface that is well prevented from occurring can be obtained.

(Effects) As described above, according to the present invention, the adhesive material for decorating the object to be coated is composed of the decorative adhesive body and the heat-shrinkable masking material that is releasably attached to the upper surface of the body. Even if this is applied to the object to be coated and coated at least on the top surface of the periphery, only the masking material will peel off by itself due to subsequent heating, and the masking material cannot be removed with tweezers or fingers as in the past. This method eliminates the above-mentioned drawbacks when peeling off the decorative adhesive through the coating film coated on its upper surface, making the work easier and faster, and removing the adhesive from the periphery of the decorative adhesive itself and the coating film. It has the effect of producing a good decorative painted object in which a good adhesion state of the waterproof adhesive material main body between the adhesive material and the adhesive material is maintained.
