Description

Double-layer glass and its manufacturing method {Insulating glass unit and manufacturing method thereof}

The present invention relates to a multilayer glass in which a plurality of glasses are laminated by a continuous interbar, by forming an inward groove facing the space between the laminated glass along the longitudinal direction of the continuous interstitial bar, and forming a sealant application part, to the inward groove It relates to a double-layer glass in which the durability of the continuous bar and glass is improved by making it easy to form the edge of the continuous bar at a right angle.

In general, windows and doors are installed in buildings for ventilation and insulation, and the windows are made of glass for transparency.

As for the windows, the heating and cooling energy of the room may be leaked to the outside through the glass surface, and accordingly, double-layer glass is installed inside the windows to minimize the outflow of the heating and cooling energy to the outside.

The double-layer glass forms an empty space between the glass by spacing the glass facing each other at a predetermined interval by installing a spacer (spacer) between the glass, and filling the empty space with dry air or an inert gas such as argon. It is designed to minimize the transfer of energy between the livers.

And, as described above, when installing double-glazed glass on the inside of a window using a gap bar, a moisture absorbent is embedded in the gap bar so that the moisture absorbent can remove moisture present in the empty space between the glass, so that dew condensation occurs on the glass surface. to prevent

As a technology corresponding to the conventional double-layer glass as described above, Korean Patent Registration No. 10-0447734 discloses a spacer for double-layer glass, which forms a spacer with an aluminum material of a long column shape with an empty interior, and the spacer After cutting to a certain length, the cut spacer is connected with a connecting member to prepare a rectangular frame, and then glass is adhered to both sides of the manufactured frame to manufacture double-layered glass.

However, the conventional double-layer glass using an aluminum cross bar requires a lot of labor in the process of cutting the bar one by one and connecting it through the connecting member, and since a gap may occur between the connecting members connecting the corners of each bar, it is necessary to check this. There was a problem that took a lot of time. In addition, due to the use of an aluminum material, there was a problem in that the portion where the rod is bonded to the glass is vulnerable to insulation. In addition, there was a problem in that it was difficult to maintain the uniformity of quality because it was impossible to check with the naked eye.

In order to solve the above problems, Laid-Open Patent Publication No. 10-2006-0118119 discloses a super window using a spacer of a flexible material and a manufacturing method thereof, which constitutes a double-layer glass by installing a spacer between two sheets of glass. However, by continuously connecting the spacer with a flexible material, it is possible to manufacture a multilayer glass without the need for a configuration such as a connecting member for connecting the spacer, thereby having the advantage of reducing the number of labor and working time.

However, in the super window using the flexible material spacer, when the spacer is bent at a right angle to form a quadrilateral frame, the 'shipping phenomenon' in which both sides of the spacer bent at right angles toward the glass swelled up, and due to this, , there was a problem in that a space was generated between the glass and the spacer.

In addition, the spacer has a flat side, so there is a problem in that the adhesion to the glass is poor.

Accordingly, there is a growing need for a multilayer glass and a method for manufacturing the same that can alleviate the phenomenon of the spacer being doubled.

On the other hand, in a situation where high-performance multi-layer glass is required, the multi-layer glass using the existing glass is faced with the problem of increasing the weight of the multi-layer glass by using aluminum interlayer and several sheets of glass, and a solution to this problem is also required.

Hereinafter, the multilayer glass of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a double-glazed glass according to an embodiment of the present invention, and FIG. 2 is a cut-away perspective view showing one side of the multi-layered glass of FIG. 1 . In addition, Figure 3 is a cross-sectional view of the laminated glass according to an embodiment of the present invention.

The present invention is a multilayer glass in which a plurality of glasses are laminated, two sheets of outer glass (10, 10') arranged in parallel to the outermost of the multilayer glass, and parallel to the inner side of the outer glass (10, 10') Two or more thin glass plates (20, 20 ', ...) disposed while forming a soft continuous bar for attaching the outer glass (10, 10 ') and the thin plate glass (20, 20 ', ...) while spaced apart from each other ( 30), but provides a multilayer glass, characterized in that an inward groove (32) facing the space between the multilayer glass along the longitudinal direction of the continuous interbar (30) is formed.

The outer glass (10, 10'), as shown in Figures 1 to 3, is composed of a first outer glass (10) and a second outer glass (10'), located at the outermost of the laminated glass it is glass The first outer glass 10 and the second outer glass 10' are formed in the same shape and size.

The outer glass (10, 10') has a relatively thick thickness compared to the inner thin glass (20, 20', ...), and serves to protect the inner thin glass (20, 20', ...) can do.

As a material of the first outer glass 10 and the second outer glass 10 ′, soda lime glass or low-e coated glass may be used.

The soda-lime glass (Soda-lime glass) is a glass mainly composed of silica, lime, and soda ash, silicate glass. Usually, it occupies most of the practical glass such as plate glass and container glass.

The low-E coating glass is an energy-saving glass that minimizes heat transfer by thinly coating a metal or metal oxide on a glass surface, and is also called low-emission glass. Low-E (low-emissivity) stands for low emissivity. The low-e coated glass is processed into multiple layers rather than being used as a single plate in nature, and the coated surface is made to come to the outside of the inner plate glass.

The first outer glass 10 and the second outer glass 10' are preferably made of low-e coated glass in terms of energy saving, but may be made of soda-lime glass.

The thin glass (20, 20', ...), as shown in Figures 1 to 3, is located inside the laminated glass serves to increase the thermal insulation performance.

The thin glass plates 20, 20', ... are positioned parallel to the first outer glass 10 and the second outer glass 10' and spaced apart from each other by a continuous bar 30 at regular intervals. It is appropriate that the thin glass plates 20, 20', ... are all formed in the same shape and size.

The thin glass (20, 20', ...) may have a slightly smaller size than the first outer glass (10) and the second outer glass (10'). When the thin glass (20, 20', ...) has a slightly smaller size than the first outer glass (10) and the second outer glass (10'), the edge portion of the thin glass (20, 20', ...) Since it is hidden inside the double-glazed glass, the risk of damage to the thin glass 20, 20', ... may be reduced.

The thin glass (20, 20', ...) is a first thin glass 20, a second thin glass (20'), a third thin glass (not shown), ... It may include, but it is appropriate to include only the first thin glass 20 and the second thin glass 20'. This means that the thermal insulation performance is greatly improved up to 4 multi-layer glass (double-layer glass with 4 outer and inner glass), but the insulation performance is increased from 5 double-glazed (double-layered glass with 5 outer and inner glass). This is because the efficiency decreases sharply. Of course, if the number of glass laminated in 5 multilayers, 6 multilayers, and 7 multilayers is increased, the thermal insulation performance continues to increase, but the increase efficiency is insignificant and in the end it will be inefficient in terms of manufacturing cost and productivity. Therefore, in the embodiment of the present invention, it is carried out on the basis of including only the first thin glass 20 and the second thin glass 20 ′.

The thin glass (20, 20', ...) is to have a thickness as thin as possible to lighten the overall weight of the laminated glass. Accordingly, it is preferable to use a material having a high elastic strength while having a thin thickness.

The present invention provides borosilicate soda-lime glass, alkali aluminosilicate glass, and soda-lime glass as the material of the thin glass (20, 20', ...) located inside the double-layer glass. In other words, the thin glass (20, 20', ...) of the present invention is formed of any one of borosilicate soda-lime glass, alkali aluminosilicate glass, or soda-lime glass to minimize thickness and weight while providing high elastic strength. have

The borosilicate soda-lime glass (Borosilicate soda-lime glass) is a tempered glass used for glass for liquid crystal display devices, it is characterized in that the elastic strength is three times higher than that of general soda-lime glass.

The alkali aluminosilicate glass (Alkali Aluminosilicate glass) is a glass used to form a light and thin. The alkali aluminosilicate glass is used for glass for liquid crystal display devices and the like, and is a glass used as various other protective glass. Alkali aluminosilicate glass is characterized in that the elastic strength is three times higher than that of general soda-lime glass.

The thin glass (20, 20', ...) of the present invention may be manufactured from general soda-lime glass. If it is manufactured with ordinary soda-lime glass, it may have an advantage in terms of cost.

4 is a perspective view of a continuous bar according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view of a continuous bar according to an embodiment of the present invention.

6 to 7 are cross-sectional views of a continuous bar according to another embodiment of the present invention.

The continuous bar 30, as shown in FIGS. 1 to 3, spaced apart the thin glass (20, 20', ...) and the outer glass (10, 10') from each other to create a space between the glass and the glass. plays a role in shaping The continuous bar 30 is attached to the thin glass (20, 20', ...) or the outer glass (10, 10') to maintain the shape of the frame. The shape of the frame will be suitably a rectangle, and on the premise that it is the same as the shape of glass, a frame of any shape such as a circle, an oval, etc. will be possible. In the embodiment of the present invention, the shape of the frame of the continuous bar 30 is carried out on the basis of a rectangular shape, which is the shape of a general glass window.

A sealing adhesive 40 is applied to both sides of the frame made of the continuous bar 30 and adhered to the thin glass (20, 20', ...) or the outer glass (10, 10'), and the outside of the double-layer glass In the direction facing, the sealant 50 is applied to finally close a gap that may occur between the continuous bar 30 and the glass.

Accordingly, the frame made of the continuous bar 30 is slightly smaller than the width of the thin plate glass 20, 20', ... or the outer glass 10, 10' so as to provide a space for the sealant 50 to be applied. It is preferable to make it small.

The continuous bar 30 is manufactured by a continuous extrusion method, stored in the form of a roll, and then released by an automated device to automatically perform the forming of the frame and cutting of the length, thereby improving workability and productivity. have.

In order to perform the automation as described above, the continuous bar 30 is made of a soft material, and as in the present invention, when the glass inside the double-layer glass is manufactured in the form of a thin plate, the soft bar is made of glass compared to the bar made of aluminum. It is advantageous in terms of safety as the possibility of damage to the bar is lowered.

The continuous interbar 30 is, as shown in FIGS. 4 to 5, an inward groove 32 is formed along the longitudinal direction toward the space between the laminated glass. In other words, the inward groove 32 is formed on one surface of the continuous interbar 30 to face the space between the thin plate glass 20, 20', ... and the outer glass 10, 10'.

It is appropriate that the inward groove 32 has a cross-section cut when the continuous bar 30 is cut to have a concave shape.

The inward-facing groove 32 serves to help the continuous bar 30 to be attached to the glass in the form of a polygonal frame, so that each corner of the continuous bar 30 can be folded close to 90°. The continuous bar 30 preferably has a shape of a frame to match the shape of the thin glass (20, 20', ...) and the outer glass (10, 10'). Accordingly, as the edge portions of the continuous bar 30 go inside the thin glass 20, 20', ... and the outer glass 10, 10', the thin glass 20, 20', ... and the outer glass It is possible to prevent the risk of damage to (10, 10') from increasing, and to improve the aesthetics by preventing a space from being formed between the thin glass (20, 20', ...) and the outer glass (10, 10'). there will be

In addition, since the thickness of the continuous bar becomes thinner by the inward groove 32 , it is easy to form a pseudo right angle (which is bent close to 90° without being bent round when the bar is broken). To explain further, a similar right angle may be formed by simply adopting a thin interstitial bar, but by using the continuous interstitial bar 30 having an inwardly directed groove 32 formed therein, while maintaining the top and bottom thickness of the continuous interstitial bar 30 constant, the edge portion By making this easy to bend, the application area of the sealing adhesive 40 is widened to increase the adhesive force, to prevent the inflow of air into the inside of the double-layer glass, and, of course, the corner portion of the continuous bar 30 to form a similar right angle naturally be able to

However, in the continuous rod 30 in which the inward groove 32 is formed as described above, a phenomenon in which a ship comes out to the side may occur. The phenomenon that the ship comes out means that the continuous bar 30 is folded to the edge and at the same time the side of the continuous bar 30 is folded and protruded from both sides and thickened.

Meanwhile, in order to prevent this, the inward groove 32 may have a tapered shape that becomes wider toward the bottom of the groove, that is, a trapezoid, as shown in FIG. 6 . Accordingly, the tapered angle should be appropriately determined according to the degree of softness of the continuous rod 30 material. If the tapered angle is insignificant, the continuous bar 30 will still protrude from both sides, and if the tapered degree is severe, a phenomenon in which the continuous half bar 30 shrinks to the center may occur. When the inward groove 32 has an appropriate angle, the force to push outward and the force to narrow inward coincide with each other to maintain a balance. As for the tapered angle, a person skilled in the art will be able to apply an appropriate angle in consideration of the material and the like.

On both sides of the continuous interstitial rod 30 , a sealant application part 34 and a continuous interstitial glass contact part 35 are formed.

The sealant application part 34 is formed in a form in which both sides of the continuous interbar 30 are dug, and both sides are dug to a predetermined depth in a direction from a predetermined height of the continuous interbar 34 toward the outside of the laminated glass. have

By means of the sealant application unit 34, the area of application of the continuous interbar 30 with the sealing adhesive 40 can be widened, and through this, the thin plate glass 20, 20', ... or the outer glass of the continuous interstitial rod 30 Adhesion with (10, 10') may be improved.

In addition, the continuous interstitial glass contact part 35 is formed in a form in which both sides of the continuous interstitial bar are raised, and has a form extending in a direction toward the inside of the double-layered glass.

The continuous interstitial glass contact portion 35 can improve aesthetics by covering the appearance of the continuous interstitial bar 30 coated with the sealing adhesive 40 when the double-layered glass is viewed from the outside at a predetermined height.

In addition, in order to alleviate the phenomenon of the ship coming out of the continuous bar 30, the sealant application part 34 of the continuous bar 30 has side grooves along the longitudinal direction as shown in FIGS. 6 to 7 ( 341) may be further formed.

The side grooves 341 may be formed in two rows, and it is also possible that one or three or more side grooves 341 are formed.

The side groove 341 may serve to alleviate the phenomenon of the continuous interstitial rod 30 coming out when the corners swell to both sides as the continuous interstitial rod 30 is folded, while the upper wall and the lower wall are gathered into the middle portion. .

In addition, when the side grooves 341 are formed in the continuous bar 30, the contact area with the sealing adhesive 40 is increased, and through this, the continuous bar 30 and the thin glass (20, 20', ...) or Adhesion between the outer glasses 10 and 10' may be increased.

Therefore, the side grooves 341 can simultaneously perform two roles: alleviating the phenomenon of the continuous rod 30 coming out and improving the adhesion.

Meanwhile, as shown in FIG. 7 , the side groove 341 may have a tapered shape that becomes wider toward the inside when the cross section is cut. When the side grooves 341 have such a structure, the contact area with the sealing adhesive 40 increases, so that the adhesive force can be further improved. In addition, by inducing the contraction direction of the side grooves 341, it is possible to more efficiently alleviate the phenomenon of the boat coming out.

In addition, the side groove 341 may be formed in a wave pattern or a zigzag pattern when viewed from the side. When the side grooves 341 are formed in a wavy pattern or a zigzag pattern, the contact area with the sealing adhesive 40 may be increased, and the adhesive force may be further improved. In addition, the side grooves 341 formed in a wave pattern or a zigzag pattern increase the frictional force in the horizontal direction compared to the side grooves 341 formed in a straight line, so as to prevent the continuous rod 30 from being pushed horizontally. can

The continuous bar 30 is formed of any one of ethylene propylene rubber, silicone rubber, olefin compound, and vulcanized thermoplastic rubber rubber with low moisture permeability to block external moisture and prevent the gas filled inside from escaping to the outside can do.

The existing continuous bar is manufactured by mixing a desiccant that can absorb moisture inside the double-glazed glass with the continuous bar. Accordingly, a gwanbong was manufactured using a material with high moisture permeability for moisture absorption. However, the existing continuous interstitial rod absorbs even moisture from the outside of the double-layer glass, and eventually, as the desiccant becomes meaningless, there is a problem that an aluminum foil must be attached to the outside.

Therefore, in the present invention, the moisture absorbent 36 can be attached to the inward groove 32 of the continuous interbar 30 while adopting the material of the continuous interbar 30 as a material having a low water permeability.

The desiccant 36 may be a composition having an adhesive force to be applied to the continuous rod 30 . That is, the desiccant 36 may be a composition that is applied and adhered to the inside of the inward groove. Alternatively, the solid form of the desiccant may be attached using a double-sided tape or the like. Most suitably, it will be preferable that the absorbent 36 is in the form of application. As a raw material of the desiccant 36, a hygroscopic compound including silica gel may be used, and any known hygroscopic material may be used as long as it is a material capable of absorbing moisture inside the multilayer glass.

The desiccant 36 is attached to the inward groove 32 of the continuous bar 30, but there is a problem in that the desiccant 36 may be separated from the continuous bar 30 before the desiccant 36 dries during the manufacturing process. In order to prevent the desiccant 36 from being separated from the inward groove 32 of the continuous rod 30 , an inward groove upper protrusion 38 may be formed at the entrance of the inward groove 32 .

The inward groove upper protrusion 38 is preferably formed to protrude from both sides of the inlet of the inward groove 32 to cover the inlet of the inward groove 32 .

The inward groove upper protrusion 38 not only prevents the desiccant 36 from being separated during the manufacturing process, but also prevents the desiccant 36 from being seen to the outside when the finished double-layer glass is viewed from the outside. It is possible to improve the aesthetics of the double-glazed glass.

Hereinafter, the above-mentioned sealing adhesive 40 and sealant 50 will be described in more detail.

The sealing adhesive 40 serves as an adhesive for adhering the continuous bar 30 and the thin glass (20, 20', ...) and the outer glass (10, 10'), and at the same time, the outside air flows into the inside of the double-layer glass. It acts as a seal to prevent ingress.

It is suitable that the material of the sealing adhesive 40 is butyl rubber, but any material capable of sealing the continuous interstitial rod 30 and the thin glass (20, 20', ...) and the outer glass (10, 10') at the same time as bonding. may be used as a material of the sealing adhesive 40 of the present invention.

The sealant 50 is applied to the outside of the continuous interbar 30 , that is, on the outer surface of the surface on which the inward groove 32 is formed, and finally closes the gap that may occur between the glass and the continuous interstitial rod 30 . plays a role

The sealant 50 is preferably made of any one of silicone, polysulfite, butyl rubber, and polyurethane.
