The material described in Publication No. 1 can be said to be extremely difficult to maintain sealing performance in a depressurized space or air layer over a long period of time under various harsh conditions as an automobile window material. In the former case, depending on the pressure reduction, it may appear distorted when looking through the glass, and in the latter case, the distance from the glass edge to the spacer is long, which can particularly narrow the field of view. When attaching to a window, it is not easy and it is difficult to ensure sufficient attachment strength.

。[0006] Also, for example, the above-mentioned German Patent Publication No. 351
7581, the visible sealing material is not always uniformly and beautifully applied and finished, especially when opening/closing or adjusting the height of vehicle door windows, which tends to spoil the appearance, and dirt and dust accumulate on the surface of the sealant. Moreover, it is difficult to clean this surface, and although the device described in German Patent Publication No. 3729036 is designed to maintain a dry state in the air layer, it cannot be said that the sealing performance is necessarily sufficient. Although it seems good to use balls as spacing members, it is not good in terms of workability, and local forces act on both glass plates, so it is not necessarily a good idea. The device described in Japanese Patent No. 263129 determines the spacing by the edge member fixed with an adhesive, which is not necessarily a good thing as it causes local force, and furthermore, the sealing performance is not sufficient and it may cause clouding in the air layer. It also tends to occur due to the usage environment or long-term use.

Furthermore, the methods described in the above-mentioned publications are not necessarily easily applicable to double-glazed glass, for example, which is a combination of an outer glass plate and an inner glass plate that is thinner than the outer glass plate.

After arranging a plurality of moldings on the entire peripheral edge surface of a layered glass plate, the molded molded portion was integrally surrounded and covered with a synthetic resin, particularly a thermoplastic resin material, by a so-called encapsulation method or the like. This makes it possible to create a strong, integral bond that is much better than conventional adhesives, has sufficient adhesive strength, and has excellent durability such as weather resistance and light resistance, making it more versatile and safer. It can improve the quality and provide high livability.
The present invention provides double-glazed glass for vehicle windows that can be made lightweight, and an effective and efficient method for producing the same.

Double-glazed glass for vehicle windows has various functions that allow it to withstand harsh environments such as temperature changes from °C to +50 °C and distortions caused by wind pressure during high-speed driving, and has sufficient long-term durability. This is to prevent deterioration of the window, and to narrow the space between the spacing member and the peripheral edge surface as much as possible so as not to narrow the field of view, making it suitable for vehicle windows with as much transparency as possible. This is for double-glazing.

That's about it. It is preferable that the synthetic resin molding is inserted between the peripheral edges of the inner and outer glass plates by about 2 to 4 mm, for example, and in some cases, this layer may be omitted without applying the sealing material. can.

言うまでもない。[0016] Furthermore, as a method for integrally molding the synthetic resin molding onto the peripheral edge of the so-called double-glazed glass, in which the inner and outer glass plates are multi-layered, the RIM method, the LIM method, etc. may be mentioned. Among these, the so-called encapsulation method is the most preferred. For example, in the case of polyurethane resin, the injection molding conditions are injection melting temperature of about 140 to 200.
°C, the injection pressure is about 130-150 kg/cm2 (discharge pressure around 3 kg/cm2), the mold temperature is about 60-70 °C, and for example, if it is vinyl chloride resin, the injection molding conditions are Injection melting temperature 170~2
The injection pressure is about 300 kg/cm2 or more at about 00°C, and at this time, the flow of the molten resin for injection is facilitated by pre-treating the peripheral edge with a primer before inserting the molding part into the molding die. In addition, it is preferable that the adhesiveness is strengthened, and the temperature of the peripheral edge is 80 to 1
It is preferable that the temperature be heated to about 00°C. Note that when the glass plate is made of various combinations of organic and inorganic materials, special consideration must be given to cracking, etc., and needless to say, consideration must be given to thermal expansion and contraction.

For example, a rubber balloon-like material containing a desiccant may be attached to the tube to adjust the pressure and humidity within the space, or it may be sufficient to simply seal and clean up afterward. Furthermore, it goes without saying that a spacer containing a desiccant may be provided integrally and tightly around the space side of the spacing member for humidity control in the space.

１を示すものである。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. However, the present invention is not limited to these embodiments. FIG. 1 is a partially enlarged side sectional view showing an embodiment of the configuration of a reinforcing member and a molded molding portion at the peripheral edge of a double glazing glass for a vehicle window according to the present invention. For example, as shown in FIG. 4, the size is about 470 mm in length and about 120 mm in width, with a black frame 10 on the inner surface,
A mixture of charcoal, silica gel, and zeolite is applied to polyisobutylene via an adhesive part 9 made of polyisobutylene at a predetermined position centered around about 8 mm on the peripheral edge of the green-toned outer glass plate 2 with a thickness of about 3 mm. A thin inner glass plate having the same shape as the outer glass plate 2 and having a thickness of about 1.5 mm is placed in close contact with a spacing member 4 having a height of about 3 mm and a width of about 5 mm. In a dry state, the inner and outer glass plates are closely attached at the adhesive part 9 in the same manner as described above so that the peripheral edge surfaces face around the entire circumference, and the two inner and outer glass plates 2 and 3 are formed with the spacing member 4. A space 6 of about 3 mm is formed to form a multi-layered glass, and the outer side of the spacer member 4 is sealed with silicone resin as a sealing material 5 to a thickness of about 3 mm to obtain a multi-layered glass. After setting the reinforcing members 7, which are urethane resin molded products, at 8 locations on the peripheral edges, that is, 2 locations on each side, so as to abut and hold the reinforcing members 7 against the edges and end faces of the inner and outer glass plates in cross-sectional view, then the molding Apply a primer to the area where step 8 is to be applied, and as shown in Figure 5, surround the peripheral edges of the double-glazed glass obtained above, that is, the peripheral edges of the inner and outer glass plates, reinforcing members, sealing materials, etc. The polyurethane resin molding 8 is set in an injection mold 12, clamped by the upper and lower molds 13 and 14, and integrally molded by the so-called encapsulation method in which raw resin is injected into the cavity space 15. This figure shows a molded double-glazed glass 1 for vehicle windows.

付けも容易となるものである。[0019] In the obtained double-glazed glass for vehicle windows, the molding extends approximately 3 times from the peripheral edge surface of the inner and outer glass plates to the sealing material.
This means that it will penetrate about 1.2 mm and will also get entangled with the reinforcing member.In addition, it supports the inner glass plate and enhances the integration of the inner and outer glass plates, resulting in extremely excellent sealing properties and completely blocking water and moisture. It has sufficient weather resistance and durability over the long term, and not only protects the peripheral edges of double-glazed glass for vehicle windows, but also improves the impact strength of the glass and improves the cushioning properties of the inner glass to protect occupants. It can reduce the laceration of the car, withstand wind pressure while driving, and is less likely to develop distortion. Furthermore, it has excellent soundproofing and heat insulation properties, and various dimensional properties have been improved, improving comfort and safety inside and outside the car. It has excellent properties and can also be made lighter.
This not only facilitates storage and transportation, but also facilitates attachment to vehicle body windows in subsequent processes.

であった。Next, FIG. 2 shows another embodiment of the present invention in which a reinforcing member is fastened and supported by a connecting member protruding from a spacing member at the peripheral edge of the double-glazed glass for a vehicle window according to the present invention. FIG. 2 is a partially enlarged side cross-sectional view showing the double-glazed glass for a vehicle window described in FIG. 3, a glass plate with a thickness of about 1.2 mm on which a PET film with a thickness of about 100 μm is attached with a PVB film with a thickness of about 0.38 mm is used, and the reinforcing member 7 is fastened with a connecting member 11 protruding from the spacing member 4. This is a double-glazed glass 1 for vehicle windows obtained in place of the one that was supported. The obtained double-glazed glass for vehicle windows was improved in reinforcement and integration even though the inner glass plate was replaced by connecting and supporting the reinforcing member with the connecting member protruding from the spacing member. In addition, the inner and outer glass plates can be connected without reducing their sealing properties, and the sealing material and molding polyurethane resin are also entwined with the connecting member to act as a core material, resulting in an integrated structure, as described in Fig. 1. They had similar effects, and in some cases even better performance.

よく得ることができる。Effects of the Invention As described above, the double-glazed glass for vehicle windows of the present invention and the method for manufacturing the same are unique in that even in a unique combination of inner and outer glass plates, the spacing member, especially the spacing member having the connecting member and the sealing The inner surface of the peripheral edge of the inner and outer glass plates is left in a U-shape by combining with materials etc. so that the synthetic resin for molding can enter, and the inner and outer glass plates, especially the outer glass plate, are reinforced with reinforcing members. A reinforcing member fastened to the spacing member by a connecting member is used to abut against the peripheral edge surfaces of the inner and outer glass plates, for example, to sandwich and integrate the inner and outer glass plates. By integrally molding the molding,
In addition to the structure of normal double-glazed glass, the molding will penetrate from the peripheral edge of the inner and outer glass plates to the sealing material, and will also become entangled with reinforcing members, etc. In addition, it will support the inner glass plate and the inner and outer glass plates. By increasing the integration of the panels, it has extremely excellent sealing performance, completely blocking water and moisture, and has sufficient weather resistance and durability over the long term, making it suitable for double glazing for vehicle windows. Not only can it protect the peripheral edges, but it also improves the impact strength of the glass plate, increases the cushioning properties of the inner glass, reduces the risk of lacerations to the occupants, and can withstand wind pressure while driving, making it less likely to cause distortion. Furthermore, the soundproofing and thermal insulation properties are improved, and various dimensions are improved, making it possible to achieve superior livability and safety inside and outside the vehicle, and to achieve weight reduction, making it ideal for storage and transportation as well as post-processing. It is possible to obtain labor-saving, safe, stable and efficient double-glazed glass for vehicle windows, which can be easily attached to vehicle body windows, and which can be fully adopted and useful for vehicles, especially automobiles.
