DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used to prevent a fire from spreading in an opening or a door of a building.
The space between two sheet glasses separated was filled with hydrogel.
The present invention relates to a fireproof glass containing a hydrogel.

[0002]

2. Description of the Related Art In the event of a fire in a building, there is a need for a window member which has fire-proofing properties such as protection against the propagation of a flame, a barrier against the diffusion of smoke, and a shield against radiant heat.

[0003] In response to the aforementioned requirements, netted glass is used for windows for fire doors. Recently, besides netted glass,
Gel-containing double-glazed structures or various heat-resistant sheet glasses have been proposed for windows on the outer walls of buildings, partitions in rooms, or windows provided in doors such as passageways.

[0004] For example, Japanese Patent Publication No. 60-24063 discloses a fire-resistant pane in which two or more glass sheets are arranged in parallel with each other and the space of the glass sheets is filled with a gel, wherein the gel has at least one kind of gel. A liquid containing an acrylic acid derivative, and wherein the gel has a high heat of evaporation, for example, 65 to 95% by weight of water
And a substance that is miscible with the gel and that can form a thermally insulating foam under heat rays, for example, 1 to 20% by weight of a soluble salt selected from the group consisting of alkali metal salts or ammonium salts. Is disclosed.

[0005] For example, Japanese Patent Application Laid-Open No. 3-286058 discloses a configuration in which water glass is sealed between a pair of transparent heat-resistant crystallized glasses opposed in parallel at a predetermined interval. .

Further, the applicant of the present application discloses in Japanese Utility Model Application Laid-Open No. 5-63558 a structure of a fire-resistant glass containing a hydrogel in which a hydrogel is filled between two glass plates.

[0007]

The color of fireproof glass containing hydrogel is determined by the type of glass plate used. Since the thickness of the glass plate to be used is large and two glass plates are used, it is difficult to match colors with the surroundings.

When used for interiors such as partitions,
The design required for the color could not be sufficiently satisfied.

SUMMARY OF THE INVENTION According to the present invention, a double-layer glass structure is formed by holding and integrating the peripheral portions of two glass plates facing each other with a space member, and a hydrogel is provided in the closed space of the double-layer glass structure. A water-containing gel-containing fire-resistant glass, wherein the water-containing gel is colored with a dye, wherein the organic pigment and dye are dissolved or evenly dissolved in a liquid of the water-containing gel. It is characterized by being dispersed.

[0010] Further, the glass plate is provided with an ultraviolet absorbing layer or an ultraviolet reflecting layer.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Two glass plates are opposed to each other in parallel via a spacer, and a sealed space formed by the two glass plates and the spacer is filled with hydrogel to form a fire-resistant glass. Is done.

[0012] The spacer is provided with at least one hole for injecting the hydrogel.

The glass plate is an inorganic transparent glass plate, which is colorless or colored, and its type or color tone,
It is not particularly limited to the shape and the like. Further, as well as bent sheet glass, various processed glass such as various strengthened glass and strength-up glass, glass with wire / net, crystallized glass, borosilicate glass or aluminosilicate glass Etc. can also be used.

The spacer and the glass plate are preferably bonded with a synthetic rubber-based non-water-permeable and tacky adhesive such as polyisobutylene, polyisobutylene-butyl or butyl. In addition, silica, white carbon, titanium oxide, magnesium silicate, aluminum silicate, etc. as a reinforcing filler in the normal adhesive, unsaturated hydrocarbon-based resin, chroman resin, terpene resin, rosin derivative, etc. as a tackifier,
In addition, a desiccant and the like can be appropriately added. Even if the vitreous plate deforms due to fluctuations in the outside air pressure or expansion and contraction of the aqueous gel, the adhesive can hold the adhesive in a wide temperature range with an adhesive force, and prevents escape of the aqueous medium in the aqueous gel. And maintain long-term stability.

Further, the outer periphery of the spacer is sealed with a similar synthetic rubber-based sealing material, for example, a sealing material such as a silicone-based, polysulfide-based rubber, polyurethane-based, or polybutadiene-polystyrene-based rubber. A filler such as heat-resistant inorganic material powder and other additives can be appropriately mixed into the sealing material. The sealing material, of course, also has tackiness, but is an important component particularly for firmly holding the glass plate and the spacer and more completely blocking the aqueous gel from the outside.

Hydrous gels include acrylic synthetic polymers such as sodium acrylate vinyl alcohol copolymer, saponified polyacrylonitrile polymer, and polyvinyl alcohol synthetic polymers such as polyvinyl alcohol crosslinked polymer. Water and an inorganic substance such as silica, etc., as appropriate, for example, 50 to 60% by weight of water, 10 to 20% by weight of an acrylic superabsorbent monomer such as sodium polyacrylate %, 20 to 30% by weight of an inorganic substance such as silica.

A dye is mixed with the hydrogel to color the hydrogel. Dyes to be mixed include azo dyes, quinone dyes, cyanine dyes, cationic dyes, phthalocyanine dyes, and the like.For pigments, for example, soluble azo pigments, insoluble azo pigments, phthalocyanine pigments, condensed polycyclic pigments, etc. Mix. As for the dye, for example, an azo dye, an anthraquinone dye, an indigo dye, or the like is mixed. In particular, a water-soluble dye is preferable from the viewpoint of compatibility with the hydrogel.

A solution of the colored hydrogel is filled in a closed space formed by two glass plates and a spacer, and irradiated with ultraviolet rays to be crosslinked and hardened.

The glass plate and the hydrated gel can be formed into a plurality of layers by appropriately changing the thickness and the like. Further, a transparent organic plate such as polycarbonate or an acrylic plate may be used instead of the glass plate. .

It is desirable to provide an ultraviolet reflecting layer or an ultraviolet absorbing layer on the glass plate to prevent the dye from being deteriorated by ultraviolet rays.

The ultraviolet reflecting layer is a metal oxide film or a metal film formed on a glass plate by a sputtering method, a CVD method, a sol-gel method or the like, and the ultraviolet absorbing layer is used for an interlayer film of laminated glass. PVB or the like.

The above-mentioned ultraviolet reflecting layer and ultraviolet absorbing layer may be provided on a transparent polymer film and adhered to a glass plate.

A silicon-based sealing material 7 is formed on the outer periphery of the spacer portion 2 and the end surface of the glass plate 3 while leaving the injection hole 4.
Then, the hydrogel 1 was injected from the injection hole 4.

The hydrogel 7 is composed of 60% by weight of water, an acrylic super-absorbent monomer 15 such as sodium polyacrylate.
0.01% of a red metal complex salt dye (Hodogaya Chemical Industry Co., Ltd. Aizen Spiron Dye RED: organic solvent soluble dye) was added to a solution in which 25% by weight of an inorganic substance such as silica was mixed.
0.03, O.D. O was mixed in three stages of 5% by weight, and colored from light red to dark. The hydrogel 1 was injected, and after degassing was completed, the injection hole 4 was sealed with the same silicone-based material as the sealing material.

After sealing, the hydrogel 1 was cured using a 120 W ultraviolet lamp to obtain a fireproof glass.

In this way, a red transparent fire-resistant glass containing water-containing gel was produced. Further, by changing the mixing amount of the red metal complex dye, the red color density could be changed.

Example 2 Instead of a red metal complex dye, a blue metal complex dye (Aizen Spiron Dye BLUE: organic solvent soluble dye) was used in an amount of 0.01, 0.03 and 0.0.
By mixing the gel with water-containing gel in three stages of 5% by weight, it is possible to produce a fire-resistant glass containing water in the same manner as in Example 1, and to produce a fire-resistant glass containing a gel from a light blue to a dark one. did it.
