Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass reinforcing film bonded to glass to prevent the fragments from being scattered when the glass is broken, and more particularly to a glass reinforcing film which can be easily bonded to a glass surface. For film.

[0002]

2. Description of the Related Art At present, a film for preventing glass scattering is provided by providing an adhesive layer on a polyester film, disposing a separator film thereon, and peeling the separator film when in use and pressing the adhesive layer on the glass surface. The polyester film is usually 50μ
Because of the thinness of about m and the strong adhesive force of the adhesive, wrinkles occur and air pockets frequently occur, so it can not be applied neatly unless you are a skilled person, and it takes a considerable amount of time to apply was there.

SUMMARY OF THE INVENTION The present invention relates to a glass reinforcing film which can be easily bonded to glass with good appearance without special skill, and which is less likely to cause wrinkles and air pockets. To provide.

SUMMARY OF THE INVENTION The present invention relates to a glass reinforcing film which can be easily bonded to glass. The gist of the present invention is to provide an adhesive layer on one side of a base film and a separator film thereon. Is disposed, and when laminated on a glass surface, the separator film is peeled off and bonded to the glass reinforcing film, and a wrinkle having a thickness of 0.05 to 0.5 mm is formed on the surface of the base film opposite to the adhesive layer. A glass reinforcing film obtained by adhering an anti-entry film.

[0005] The reinforcing film of the present invention can effectively prevent wrinkles and air pockets at the time of laminating by increasing the overall thickness and giving the film a stiffness.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. FIG. 1 is a sectional view of an example of the glass reinforcing film of the present invention. The glass reinforcing film 1 of the present invention is the same as a conventional film in that an adhesive layer 3 is provided on one side of a base film 2 and a separator film 4 is disposed thereon.

Here, as the base film 2, a transparent and high-strength plastic film can be employed, but a biaxially stretched polyethylene terephthalate film having a thickness of about 50 μm can be suitably used. The base film 2 may have a heat ray blocking effect by vapor deposition or the like. If the thickness of the base film 2 is too large, the transparency is lowered, and the effect of preventing the glass from scattering is rather lowered. Therefore, the thickness is naturally limited, and it is not preferable to make the base film 2 too thick.

A feature of the present invention resides in that a wrinkle-preventing film 6 having a thickness of 0.05 to 0.5 mm is adhered to the base film 2 on the side opposite to the adhesive layer 3. If the thickness of the anti-wrinkle film 6 is less than 0.05 mm, it is not possible to prevent wrinkles or air pockets during construction. On the other hand, when the thickness is larger than 0.5 m, it is difficult to cut the glass plate into a size, and the cost increases.

As the anti-wrinkle film 6, a relatively rigid plastic film, for example, a film of polyvinyl chloride, polyprolene, polycarbonate, polyethylene terephthalate or the like, or paper can be used. More specifically, a biaxially stretched polyethylene terephthalate film having a thickness of about 100 μm can be suitably used.

As the wrinkle-preventing film 6, an embossed film, a perforated film, or a net-like film may be used. When such a film is used, there is an advantage that the film can be easily wound into a roll even when the film is thick, or the curling is reduced when the film is flattened during use, thereby facilitating construction. Further, if the anti-wrinkle film 6 is printed in a grid pattern, it is easy to measure the size of the glass window and cut the reinforcing film to the size.

The anti-wrinkle film 6 comprises an adhesive 5
The base film 2 is peelably adhered to the base film 2. The adhesion between the anti-wrinkle film 6 and the base film 2 is as follows.
The adhesive strength is set lower than the adhesive layer 3 for adhering to glass. If the adhesive force is too weak, the anti-wrinkle film 6 may be peeled off during storage or transportation, and if it is too strong, the whole glass reinforcing film is removed from the glass when the anti-wrinkle film 6 is peeled off after bonding to glass. It is preferable to adjust the adhesive strength to about 30 to 70% of the adhesive strength of the adhesive layer 3 because there is a risk of peeling and the adhesive may remain on the base film 2. As the pressure-sensitive adhesive layers 3 and 5, polyester-based, acrylic-based,
A rubber-based or silicone-based adhesive can be appropriately selected and used.

The method for applying the reinforcing film of the present invention will be described. First, the reinforcing film is cut into the same size before being attached to the glass surface. And separator film 4
Is peeled off, and the pressure-sensitive adhesive layer 3 is pressed against the glass surface and adhered. At this time, since the reinforcing film is thick and stiff, there is no wrinkles or air entanglement, and it can be stuck neatly even by non-experts. Edge (corner) during construction
Only the separator film is peeled off and adhered to the end of the glass surface, and then the separator film is peeled off little by little while being adhered, whereby the film can be easily adhered. Next, the anti-wrinkle film 6 is peeled off and removed, and the attachment is completed.

[0013]

The film for reinforcing glass of the present invention has a thickness of 0.05 to 0.1 mm. By incorporating an anti-wrinkle film having a thickness of 1 mm, it is possible to apply a good appearance without wrinkles or air pockets without increasing the thickness of the base film adhered to the glass, even if it is not a skilled person. Can be.
Conventionally, when a large area was constructed, it was necessary to work by two people. However, the present invention product can be sufficiently pasted by one person.
