Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl chloride shield adhesive film produced by a casting method (solution casting method), and more particularly to a detachable shield adhesive film for a helmet.

[0002]

2. Description of the Related Art Conventionally, in a helmet worn when driving a motorcycle, a shield is transparent to smoke, transparent to smoke, and transparent from the viewpoint of visibility depending on the weather or day and night while the motorcycle is running. You may want to change the color to yellow. Therefore, in addition to the transparent shield, it was supposed to carry a shield such as smoke and replace the shield as needed.

[0003]

However, the conventional shield of this type as described above is relatively hard and expensive in terms of cost, and it takes time and effort to replace the shield. Furthermore, there were problems such as the need for a shield space for touring. The present invention was devised to solve the above-mentioned problems, and is inexpensive and can easily have a color such as smoke, yellow, and UV cut, or its function, and can be visually recognized from the optical characteristics. It is an object of the present invention to provide a helmet shield adhesive film which is free from problems in terms of sex and can be removably attached to a cubic curved surface and the like repeatedly.

[0004]

In order to achieve the above object, in a detachable shield attachment film for a helmet of the present invention, a shield film attached to a shield surface of a helmet, the film comprising: Is a soft vinyl chloride resin having self-adhesiveness produced by a casting method.

[0005]

[Advantage] The detachable shield sticking film for vehicles constructed as described above can be easily stuck to a mirror-like body such as glass or transparent acrylic, does not become sticky even if touched by hand, and is easy to peel off. It does not have to worry about glue residue or dirt after peeling. It is economical because it can be peeled off and attached again. Furthermore, since it fits well on curved surfaces and does not peel off, it is optimal if used as a shield for motorcycle helmets and has excellent transparency, so even if it is attached to the opposite side of the glass, the transparency will be impaired. Never.

EXAMPLES Examples will be described below with reference to the drawings. FIG. 1A is a view showing a state in which a removable shield adhesive film for a vehicle of the present invention is adhered to a helmet shield, and FIG. 1B is a rear surface of a helmet shield which is removable for a helmet. It is sectional drawing which stuck the shield sticking film, (c) is sectional drawing which stuck the removable shield sticking film for helmets on the surface of the shield of a helmet. In FIG. 1, reference numeral 1 denotes a shield of a helmet 3, to which a detachable shield attachment film 2 is attached on the front surface or the back surface thereof, which may be smoked or colored as necessary, It depends on the time. The removable adhesive film 2 is made of vinyl chloride resin as a material, and it is easy to fit even a three-dimensional plate such as glass or acrylic resin, and is not peeled off. Further, the shield adhesive film 2 itself can be attached and used any number of times without being soiled even after it is peeled off, which is economical. Furthermore, since it is made of a soft material, it does not require a space for storing, which is convenient. Further, since the material itself has no directionality, it is excellent in transparency, and its transparency is not impaired even if it is used for a long period of time.

Next, an example of the composition of the removable adhesive film and the manufacturing method will be described below. Polyvinyl chloride resin is dissolved in tetrahydrofuran, which is an organic solvent, and phthalic acid ester is further added as a plasticizer to prepare the following dope composition solution. Formulation example Polyvinyl chloride resin 50 kg Dioctyl phthalate 4 kg Methyl ethyl ketone 250 l Toluene 50 l This solution was made in a dissolution tank, adjusted in viscosity, filtered with a filter, defoamed in another tank, and cast from a hopper. The solvent is removed in a casting drum or band, peeled off, wound up and dried in a dryer, and then cut into a predetermined size to obtain a vinyl chloride film. The product thus produced has good adhesiveness as described above, and also has good peelability,
Since it has excellent glossiness and no directionality, it has advantages such as good transparency and strength evenly in all directions.

[0008]

EFFECTS OF THE INVENTION Since the detachable shield attachment film for a helmet of the present invention is excellent in transparency because it is configured as described in detail above, it not only looks good at a distance, but also causes eye strain. Since it does not peel off and does not stain the base material after peeling because it is easy to fit into a complicated curved surface such as a cubic curved surface, it can be used any number of times and is inexpensive in cost. Also, since it has no directionality, it is strong against tensile force due to bending etc. in any direction,
It has the effect that it is not easily deteriorated.
