Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to glass used for architecture, lighting, decoration, etc.

[Background technology]

Conventionally, glass plates made of glass alone have been mainly used for glass used for architecture, lighting, decoration, etc., but for glass plates that require particular strength, a thermoplastic film is sandwiched between two glass plates. Wired glass sheets are used, which are made by inserting a wire mesh in the middle during the rolling process of bonded laminated glass or molten glass, and for items that require insulation, double-glazed glass with two sheets of air sealed is used. It is used. However, laminated glass can prevent the scattering of fragments when the glass plate is broken, but its strength is insufficient, while glass sheets with metal mesh have high strength1 and can prevent the scattering of fragments, but there is a gap between the metal mesh and the glass. This has the problem of restricting its use for lighting and decoration because it generates fine racks and unpleasant scattered light.

[Purpose of the invention]

An object of the present invention is to provide double-glazed glass that has high strength, does not scatter fragments when broken, does not generate fine racks between the mesh and the glass, and does not generate scattered light.

[Disclosure of the invention]

The present invention features a multi-layered glass made by integrating a glass plate with stress relaxation layers interposed on the upper and lower surfaces of an organic fiber network, which has high strength and prevents fragments from scattering when broken. In addition, since there is a stress relaxation layer between the organic fiber network and the glass plate, the stress of the organic fabric is relaxed, and cracks do not occur between the organic fibers and the glass plate. Detailed explanation.

Examples of the organic fiber network used in the present invention include polyester fibers, polyamide fibers, polyvinyl alcohol fibers, polyurethane fibers, cotton, silk paper, hemp and other organic fiber networks,
The net-like body is a mesh, rough cloth, non-woven fabric, net, cheesecloth, woven cloth, etc., and the material of the organic fibers and the shape of the net-like body are not particularly limited and are arbitrary. Stress relaxation layers include epoxy resin, acrylic resin, unsaturated polyester resin, phenol resin, melamine resin, polyamide, polyimide,
Organic or inorganic binders such as rubber, mixtures, modified products, and inorganic alkali silicates can be used. The combination of an organic fiber network, a stress relaxation layer, and a glass plate includes a glass plate, a stress relaxation layer, a metal network, a stress relaxation layer, and a glass plate, and a stress relaxation layer and an organic fiber network on the outermost side of the glass plate. , stress relaxation layer, and glass plate are repeated to form laminated glass. Usually, a stress relaxation layer is interposed between the organic fiber network and the glass plate, eliminating the air layer, but it is also possible to leave only the air layer between the organic fiber networks to provide heat insulation properties. . Furthermore, the organic fiber network can be arranged in a design manner to further improve the decorative properties.

The present invention will be explained below using examples.

Example 1 Thin glass sheets with a thickness of 1.3M coated with an epoxy resin adhesive on one side were coated with adhesive on the top and bottom surfaces of kelamide cheesecloth (manufactured by Unitika Co., Ltd., product number Cheesecloth No. 100) with thicknesses o and iwI. Double glazing was obtained by placing and integrating the glass with its surface facing the cheesecloth.

Example 2 On the top and bottom surfaces of the same cheesecloth as in Example 1, 1.3-thick thin glass sheets coated with an inorganic alexicalite silicate binder on one side were placed and integrated with the binder-coated surface facing the cheesecloth. Double glazing was obtained.

Conventional example A commercially available wire mesh glass plate with a thickness of 5 μm was used as a conventional example.

〔Effect of the invention〕

As clearly shown in Table 1, the performance of the glass plates of Examples 1 and 2 and the conventional example was good, confirming that the double glazing glass of the present invention was superior.
