Description

Glued glass film manufacturing method

The invention relates to glued glass, in particular to a method for producing a laminated glass film.

Referring to FIG. 1A, a glued glass is shown, which is mainly manufactured by placing a layer of soft transparent plastic (PVB) 12 over the first piece of glass 11, after flattening, placing a second piece of glass 13 at the top, and then clamping. Fixing, the first stage of pressure is slightly warmed and defoamed, the residual air in the middle is removed, and then high pressure and high temperature bonding is performed, so that the first and second sheets of glass 11, 13 are adhered to the soft plastic 12.

In addition, if a functional film is to be placed at a local position in the glued glass, if the film is directly attached between the glass and the soft plastic, it is easy to affect the adhesion of the glass to the soft plastic, which will affect the adhesion of the glued glass to the glass fragments. The function of the glue, which affects the safety of the glued glass, such as the TW M481234 patent, as shown in FIG. 1B, shows a glued glass with a functional film sandwiched between soft plastics sandwiched between two glasses 16 for use. Two half-thick soft plastics 17 sandwich the film 18 between two pieces of soft plastic 17 for added safety. However, a soft plastic 17 becomes two overlaps. In addition to increasing the probability of residual bubbles and affecting the yield of the bonded glass, the glued glass is often produced in a large area, so that in the case of low yield, The production cost of the wear and tear is also relatively high.

It is an object of the present invention to provide a method of manufacturing a laminated glass film which substantially reduces manufacturing costs.

In order to achieve the foregoing object, a method for manufacturing a laminated glass film according to the present invention comprises the steps of: (A) forming a receiving hole in a first soft transparent plastic; and (B) placing the first soft transparent plastic. On a first piece of glass; (C) placing a soft transparent plastic sandwich containing a film in the receiving hole, and the thickness of the soft transparent plastic sandwich is equal to or less than the depth of the receiving hole; Covering a second piece of glass and sandwiching the first piece of glass with the second piece of glass; (E) performing defoaming; and (F) performing high temperature and high pressure bonding.

Preferably, after the step (B), the first soft transparent plastic is flattened, and the receiving hole is adjusted to an appropriate position.

Preferably, the soft plastic sandwich is such that the film is sandwiched between two second flexible transparent plastics.

Preferably, the second soft transparent plastic is made of polyvinyl butyral (PVB).

Preferably, the film is a reflective layer for generating a reflective surface.

Preferably, the first soft transparent plastic is made of polyvinyl butyral (PVB).

Preferably, the film is made of a cyclic olefin polymer (COP) material.

Therefore, the present invention adopts a method for partially treating a film, mainly to reduce the film bonding operation from a large-area glued glass to a small area, that is, to sandwich a small area of the soft transparent plastic sandwich. Reduce the production cost; at the same time, the residual bubble that will affect the yield is reduced in the soft transparent plastic sandwich. Even if the defective product is produced, only a small area of the soft transparent plastic sandwich, instead of the whole piece of glued glass, can effectively reduce the production. Cost; In addition, the small area of the soft transparent plastic sandwich is also easier to deal with the problem of uneven thickness, which can really reduce the production cost.

The present invention has been described in connection with the preferred embodiments of the present invention in accordance with the accompanying drawings.

Before the detailed description is made, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 2, FIG. 3A to FIG. 3C, a method for manufacturing a laminated glass interlayer film according to an embodiment of the present invention comprises the following steps:

Referring to FIG. 2 and FIG. 3A, (A) a receiving hole 21 is formed in a first flexible transparent plastic 20; in the embodiment, the first soft transparent plastic 20 is made of polyvinyl butyral (PVB); The receiving hole 21 can be made by cutting, and the receiving hole 21 is in a rectangular hole shape.

Referring to FIG. 2 and FIG. 3B, (B) the first soft transparent plastic 20 is placed on a first piece of glass 30. In this embodiment, after the step, the first soft transparent plastic 20 is flattened. And adjusting the receiving hole 21 to an appropriate position.

Referring to FIG. 2 and FIG. 3B, (C) a soft transparent plastic sandwich 40 containing a film 41 is placed in the receiving hole 21, and the thickness of the soft transparent plastic sandwich 40 is equal to (or less than) The depth 21D of the accommodating hole 21; in the embodiment, the soft plastic sandwich 40 is such that the film 41 is sandwiched between two second flexible transparent plastics 43; in the embodiment, each of the second soft transparent plastics 43 is a material of polyvinyl butyral (PVB), and the film 41 is a reflective layer for generating a reflecting surface.

Referring to FIG. 2, FIG. 3B, and FIG. 3C, (D) a second piece of glass 50 is attached, and the first piece of glass 30 and the second piece of glass 50 are clamped by the tool. (E) performing defoaming; and (F) performing high temperature and high pressure bonding. Step (E) and step (F) are respectively performing the first stage of pressure and slightly degassing, removing the residual air in the middle, and then performing high pressure and high temperature bonding, so that the first and second sheets of glass 30, 50 are adhered. On the first soft transparent plastic 20 having the soft transparent plastic sandwich 40.

The above description is the description of each step of the embodiment of the present invention. The effects of the present invention are explained below.

The method for partially treating a film according to the present invention is mainly to prepare a small piece of a soft transparent plastic sandwich 40 containing the film 41 in advance, that is, to process the sandwich film 41 on a small-area soft transparent plastic sandwich 40 to treat the difference in total thickness. The problem is that a soft transparent plastic sandwich 40 having the same or less than the thickness of the first soft transparent plastic 20 in the glued glass is formed; before the first and second glass 30, 50 are glued, the first soft transparent plastic 20 is cut off. a accommodating hole 21 having the same area as the soft transparent plastic sandwich 40. After the first soft transparent plastic 20 having the accommodating hole 21 is laid on the first glass 30, the soft transparent plastic sandwich 40 is placed in the first In the accommodating hole 21 of the soft transparent plastic 20, pressure-heating bonding is performed, and the soft transparent plastic sandwich 40 is melted and seamlessly combined with the surrounding first soft transparent plastic 20 at a high temperature. Accordingly, the present invention has at least the following effects.

Effectively reduce production costs. The invention discloses a method for manufacturing a laminated glass interlayer film, which mainly comprises shrinking a film-forming operation from a large-area glued glass to a small area, that is, sandwiching a small area of the soft transparent plastic sandwich 40. Work, in order to reduce the production cost; at the same time, the residual bubble which will affect the yield is reduced in the soft transparent plastic sandwich 40, even if the defective product is produced, only a small area of the soft transparent plastic sandwich 40, rather than the entire piece of glued glass The utility model can effectively reduce the production cost; in addition, the soft transparent plastic sandwich 40 of a small area is relatively easy to handle the problem of uneven thickness, and can indeed reduce the manufacturing cost.
