Description of the invention (1) [Application fields in the industry] The present invention relates to multilayer glass, and more specifically to multilayer glass with thin space and thin overall thickness. Although the multilayer glass according to the present invention has a small thickness, it has a high heat-insulating property, so it has an energy-saving effect. It can be used in a building, or a tram window, a display case for storing food, or in a frozen display, for example. Cabinet, or refrigerated display cabinet. Furthermore, it can be used for openings that need to be thermally isolated and must have transparency. [Advanced technology] In recent years, the effective use of energy resources has attracted much attention. Multi-layered glass has also been used in buildings, thermal insulation, and refrigerated containers. The multilayer glass currently manufactured is constructed by sealing a limited space formed by a glass plate with a sealant, and then sealing the sealed space with dry air or using a desiccant such as silicone to maintain a dry state. Recently, in order to improve the energy-saving effect of multilayer glass, it has also been proposed to use a combination of multilayer glass and transparent thermal insulation film. However, because the space (thickness) of multilayer glass is usually more than 6 mm, and the thickness of a piece of glass is generally about 3 mm, the overall thickness of the multilayer glass is at least 12 mm. [Problems to be Solved by the Invention] Multi-layer glass' is usually used in the form of a frame. For example, apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) to this paper size ----'--------- install i — (Please read the precautions on the back before filling this page) Order ··-Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs-4-1238152 A7 ___B7____ V. Description of the Invention (2) (Please read the precautions on the back before filling this page) Refrigerated or frozen food materials The window door of the display cabinet is expected to reduce the thickness of the lintel to maximize the storage capacity. When the thickness of the multilayer glass is thicker, the overall weight of the lintel including the frame is increased. Therefore, the industry is also committed to reducing the thickness of multilayer glass to reduce the overall weight. Recently, as an example, a glass thickness of 2.7 mm is used. However, from the viewpoint of mechanical strength, the industry also believes that such a glass thickness has reached the limit that the glass can withstand. On the other hand, the space in the space becomes thinner, and due to the problems of reduced heat insulation function and the structure of the spacer that maintains the space, the space must be at least 6 mm as mentioned above. The spacer has a structure used in the past, which has a space for holding a desiccant, and in order to ensure that the distance between the two sheets of glass is kept at a certain width, as shown in Figure 2, the heat-insulating shape is a mouth shape. The closed space has slits for air circulation. However, it is difficult to set the glass interval below 6 mm as long as a spacer with such a cross-sectional shape is used. [Means to solve the problem] Printed by the inventors of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, the inventors conducted various investigations on the separator structure of multilayer glass, and found that the cross-section was barrel-shaped (U-shaped The shape of the separator with a concave shape or a structure similar to these shapes can on the one hand make the thickness of the separator thin and retain the space for the desiccant to achieve the invention. According to the present invention, a multilayer glass formed of at least two glass plates to maintain a space between the two glass plates, a desiccant contained in the separator, and a sealant is provided. The following items are applicable to the Chinese national standard (CNS) A4 specification (210 X 297 mm) for this paper size: -5- 1238152 A7 ___ B7__ V. Description of the invention (4) (Please read the precautions on the back before filling in this Sheet), it is used to fix the spacer 1 at a certain position on the glass plate and has a sealing effect. That is, the double-sided adhesive tape 6 is pasted on the position where the spacer 1 of the glass plate is to be fixed. It is easy to fix the spacer 1 at a certain position by pasting the spacer 1 thereon. In Fig. 1, the spacer 1 is installed between two glass plates. In addition to the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the two glasses are printed and held at a certain interval while forming a desiccant. Function of accommodating space 7. The space 7 must be provided with a space for containing the desiccant particles without the particles being crushed by the glass plate, and a space volume capable of containing a sufficient amount of the desiccant. In space 7 in FIG. 1, although the desiccant particles are not shown, the size of the desiccant particles is smaller than the interval between the two glass plates formed in space 7 (the correct size is subtracted) The width after the thickness of the separator) is appropriate. Specifically, the particle size of the desiccant is 30 m e s h p a s s (30 mesh per inch), and a particle size of 40 mesh pass (40 mesh per inch) is suitable. If the particle size of the desiccant is smaller than the above range, not only the filling process of filling the desiccant into the separator 7 becomes troublesome, but also the desiccant will leak to the outside of the separator 1 (the space portion of the glass plate). It's not appropriate. On the other hand, if the particle size of the desiccant is larger than the above range, it is not only necessary to increase the interval formed by the separator, but the desiccant particles contained in the space 7 may be crushed by the two glass plates. Not suitable. As a desiccant, of course, it must have the ability to absorb moisture, and it must have the ability to absorb organic solvents. The organic solvent 'is a solvent produced by an adhesive, a polycarbonate, or a sealant. As a desiccant, for example, molecular sieve (molecular sieve), sand rubber, and carbon paper can be used in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 1238152 A7 B7 Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the employee consumer cooperative V. Description of the invention (5) Calcium acid, etc. In FIG. 1, the double-sided adhesive tape 4 attached to the inner side of the separator 1 is the function of assembling workability of the multilayer glass of the present invention, filling of a desiccant, and maintaining the assembled multilayer glass. It can play an excellent function. That is, the multilayer glass of the present invention requires a thin spacer of a specific shape in order to thin the entire thickness. Because of this, the space 7 formed by the spacer is not only small, but also the spacer itself has an open shape. Therefore, it is extremely difficult to accommodate the desiccant particles in the space 7 sufficiently. However, the spacer used in the present invention, on the side forming the spacer space 7 (that is, on the opposite side of the spacer in surface contact with one of the glass plates), is affixed with double-sided tape 4 in advance, so that When the separator 1 attached with the double-sided adhesive tape 4 comes into contact with the desiccant particles, the desiccant particles are uniformly attached on the surface layer of the double-sided adhesive tape 4 inside the separator 1. The method for filling and attaching the desiccant particles to the inner side of the separator is extremely simple, and it is possible to attach a large amount to the surface layer. Then, a separator with desiccant particles adhered to the inside in the form of a surface layer is fixed on the surface of the glass plate with the tape 6 interposed on both sides, as long as another glass plate is superposed thereon. The double-sided adhesive tape 4 adhered to the inner side of the separator in this way can make the thin multilayer glass of the present invention easy to assemble by using its aforementioned effect, and has a desiccant containing workability that is easy to implement. Therefore, the double-sided adhesive tape 4 shown in Fig. 1 provided inside the spacer of the present invention does not necessarily have to be an adhesive tape, as long as it has the same function, other objects can be used. That is, a thin layer with an adhesive may be formed inside the separator. -------------- Loading --- (Please read the precautions on the back before filling this page) · -I line.

Description of the Invention (6) On the other hand, the 5th side of Figure 1 is followed by 5, which can be used as before The spacer 1 and the glass plate 2 are sandwiched by a line or a point, preferably as shown in FIG. 1, and can be expanded and extended to form a space 7 for use. With this design, the desiccant particles contained in the space 7 are fixed in a certain place by the bonding function and used with the double-sided adhesive tape 4 to prevent the desiccant displacement caused by the vibration of the multilayer glass. . The double-sided adhesive tape 5 preferably uses a polyester film as a base film and is preferably coated with an acrylic adhesive on both sides. The shape of the separator of the present invention is a plate-shaped molded body made of polycarbonate. When it is placed between two glass plates, at least one of them is a contact structure with a substantially linear line or point on the glass surface, and is on the other surface. The glass surface is preferably in surface contact. Although the thickness of such a spacer is generally 0.3 to 0.7 mm, and preferably 0.4 to 0.6 mm, the thickness can be changed in some ways depending on the shape, and the thickness is not necessarily uniform. As the material of the separator, the use of polycarbonate resin has the advantages of light weight, high rigidity, no deformation, and heat resistance. Furthermore, it has a thermal insulation effect because of its low thermal conductivity. The cross-sectional shape of the spacer may be the shape shown in FIG. 1, and the cross-sectional shape shown in (1) to (5) of FIG. 3 may also be used. The separator is between two glass plates, forming a closed space and a communication path for gas circulation. For example, the situation of spacer 1 in Fig. 1 is the same as that in Fig. 3 (1) or (4). The end of the spacer on the left is not in contact with the glass plate 2, and there is a narrow gap. This interval (d 1) is sufficient as long as a gas is allowed to flow, and it is necessary that the interval is such that the desiccant particles cannot pass through. You'll also be able to connect to the road.

Description of the invention (7) A small hole (d 2) as shown in (2) or (3) in Figure 3 is set in the spacer. In addition, as shown in FIG. 3 (5), even if the end portion of the closed space side is in point contact with the glass plate, as long as there are a few gaps in the sealed portion, the structure may be partial to have The jagged surface comes into contact with the glass plate. As mentioned earlier, the size of the communication path for gas circulation must be such that the desiccant particles do not pass through. The ideal shape of the partition surface is as shown in Figure 3 (1) ° The multilayer glass of the present invention is arranged between the two glass plates in the manner described above, and at the same time, it is generally used in the sealing of multilayer glass. Agent to keep the internal gas dry. The sealant is used in the usual way. The sealant is filled between two glass plates from the outside of the separator, and is shown as sealant 3 in Figure 1. As the sealant, a user generally used in multilayer glass can be used. Examples of the sealant include poly (isobutylene) -based, polysulfide (polysulfide) -based, silicone-based, and polyurethane-based ones. Among these, polysulfide compounds are preferred. These materials are extremely desirable because of their low water vapor transmission rate, their ability to maintain adhesion for long periods of time, and their excellent followability in the direction of tension. For the multilayer glass of the present invention, it is ideal to install a transparent surface heating element inside the single-sided glass plate, and by doing so, condensation can be prevented or even suppressed. As a method for mounting the transparent surface heating element on the inside of the glass plate, a method known in multilayer glass can be used. For example, on the surface of a glass plate, tin or indium oxide; gold or silver metal, or a coating of these alloys can be formed by sputtering or sintering, or it will be from the above --- ----------- Pack 1 (Please read the precautions on the back before filling in this page) Order ··-·· This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ) -10- 1238152 A7 B7 V. Description of the invention (8) The method in which the film formed by the coating film is adhered to a glass plate is also possible. When a transparent surface heating element is installed, electrodes such as silver or gold are installed at both ends of the surface. When using the voltage, the surface can be heated to prevent condensation. (Please read the precautions on the back before filling this page.) In addition, the multilayer glass of the present invention has a transparent heat-insulating film on the inside of the single-sided glass plate, which can further strengthen the heat-insulating function of the multilayer glass. That is, the multilayer glass of the present invention has a thin space portion, and if a transparent heat-insulating film is mounted on it, it has a great effect to make up for the deficiency of its heat-insulating effect. The transparent heat-insulating film itself is sold as a finished product and can be directly used. Further, in the multilayer glass of the present invention, it is preferable that argon is enclosed in the space portion. The sealing of argon can improve heat insulation and soundproofing effects. The multilayer glass of the present invention can be used in various fields because it has a thin overall thickness and has a heat-insulating effect and an effect of preventing dew condensation. In particular, when the multilayer glass is used as a window in a refrigerated or frozen display case, the storage volume can be increased and the window can be easily opened and closed ', which has excellent convenience.
