Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing material using an uncured clay-like silicone rubber material, a sealing material for a netted glass using the same as a netted glass, and a net using the sealing material. The present invention relates to a method of constructing glass.

[0002]

2. Description of the Related Art Conventionally, there has been known a netted glass in which a steel wire is inserted in a glass so that when a glass plate (hereinafter, simply referred to as glass) is broken due to a fire or the like, the broken pieces are not scattered. ing. This netted glass is cut using a diamond cutter or the like in the same manner as ordinary glass, but the wire is exposed at the cut end. Accordingly, if the netted glass is used in a state where the waterproofness is insufficient, rust is generated on the wire rod, and when the rust proceeds further, the glass strength is reduced. When thermal stress, impact force, or the like is applied to the glass in this state, the glass is broken. Such rust is particularly likely to occur in a humid place such as a bathroom or a pool.

[0003] Therefore, it is necessary to prevent moisture from coming into contact with the exposed wire at the cut end of the netted glass.
For example, there is a method of applying a rust inhibitor to the edge of the netted glass. However, this method has a drawback that the rust inhibitor deteriorates with time and the rust prevention becomes insufficient.

[0004] For this reason, a method of sealing the edge of the netted glass is generally employed. FIG. 6 is a sectional view showing a member used for this sealing, and FIG.
Represents butyl rubber, and (b) represents an aluminum tape. The butyl rubber 31 has a height L in its cross section.
11 is about 1 mm, and the width L12 is about 5 mm. The butyl rubber 31 has its hardness adjusted and the adhesive component bleed to impart adhesiveness only to its surface (the surface has adhesiveness, but has self-shape retention). The reason why butyl rubber 31 is used as the sealing material is that it is excellent in water barrier properties. The aluminum tape 32 has a width L13 of about 20 mm and a thickness of about several tens of μm. On one side of the aluminum tape 32, an adhesive layer 32a is provided.

FIG. 7 shows that butyl rubber 31 is added to the netted glass 1.
FIG. 3 is a cross-sectional view showing a state in which is adhered. In this way, the wire 2 projecting from the cut surface of the netted glass 1 is covered with the butyl rubber 31 (first step). In this case, the thickness of the netted glass 1 is about 6.8 mm,
Although slightly thicker than the width of the butyl rubber 31, the netted glass 1
When the butyl rubber 31 is press-bonded to the cut surface, the butyl rubber 31 is slightly deformed, but almost retains its shape to cover the net end surface of the cut surface of the netted glass 1. Subsequently, as shown in FIG. 8, an aluminum tape 32 is further applied from above the butyl rubber 31 (second step). The reason why the aluminum tape 32 is attached is to prevent adhesion of dust and the like and to facilitate handling since the surface of the butyl rubber 31 has adhesiveness.

[0006]

However, in the above-mentioned conventional sealing method, butyl rubber 31 is first adhered,
Subsequently, it is necessary to perform a two-step process of attaching the aluminum tape 32, and thus there is a problem that the manufacturing cost is high.

[0007] Therefore, an object of the present invention is to seal the edge (cut surface) and other portions of the netted glass easily and inexpensively and to withstand long-term use.

[0008]

In order to solve the above-mentioned problems, the invention of claim 1 (sealing material) applies an uncured clay-like silicone rubber-based material to one side of an aluminum tape. It is characterized in that it is shaped and attached in the longitudinal direction of the tape.

[0009] The invention of claim 2 (sealing material for glass with a net) is characterized in that an uncured clay-like silicone rubber-based material is formed on one surface of an aluminum tape into a ridge, preferably with a predetermined required amount. The tape was shaped and adhered in the longitudinal direction of the tape, and the silicone rubber-based material was provided over the entire range of the width of the aluminum tape. A projection having a substantially trapezoidal cross section is formed.

According to a third aspect of the present invention, there is provided a method for constructing a netted glass using the netted glass sealing material according to the second aspect, wherein a cut surface of the netted glass is provided with the netted glass sealing material. In a state in which the cut surface of the meshed glass and the temporarily bonded meshed glass sealing material are inserted into the engagement portion of the pressure roller provided with an engagement portion having a substantially concave cross section on the outer peripheral edge. Rolling the pressure roller along the cut surface of the screened glass,
The method is characterized in that the meshed glass sealing material is bent into a substantially concave shape to cover the edges of the meshed glass, and then the silicone rubber-based material of the meshed glass sealing material is cured.

[0011]

According to the first aspect of the present invention, the silicone rubber-based material is easily plastically deformed when pressed against the object to be sealed, and then hardens to block the object from outside air. Thereby, sealing can be performed in one step. Further, since the silicone rubber-based material is excellent in durability and weather resistance, the sealing effect can be maintained for a long time.

According to the second aspect of the present invention, when the cut surface of the netted glass is sealed, the wire exposed on the cut surface is reliably sealed by the projection of the silicone rubber-based material. First, it is sealed with a silicone rubber-based material up to the outer edge on the front side. Therefore, the rust prevention effect of the wire can be enhanced.

According to the third aspect of the present invention, after the sealing material for the glass-filled glass is temporarily bonded to the cut surface of the glass-filled glass, the pressure roller is rolled along the cut surface of the glass-filled glass. Both side portions of the sealing material are bent to the surface side of the netted glass by a pressure roller. Thus, the edge of the netted glass can be sealed in one operation.

[0014]

As the catalyst, both a titanium catalyst and a tin catalyst are used. The titanium-based catalyst is added for the purpose of improving the shelf life such as pot life and the like.
0.1 to 1.0 part by weight, preferably 0.2 to 0.8 part by weight, is added to 00 parts by weight. The tin catalyst is added for the purpose of accelerating curing and the like, and is added in an amount of 0.02 to 0.1 part by weight, preferably 0.03 to 0.07 part by weight, based on 100 parts by weight of the organopolysiloxane.

Titanium-based catalysts are represented by alkyl titanates and the like. Specifically, as the carbon number of Ti (OR) ₄ , in particular, the alkyl group becomes smaller, the curing speed becomes faster and hydrolysis becomes more likely to become unstable. And those wherein the alkyl group is ethyl, propyl, amyl, hexyl or butyl. The titanium-based catalyst is an organic acid salt of tin (R ₁ Sn

As the non-reinforcing filler, the inorganic pigment, and the fungicide, well-known materials are used, and appropriate amounts are blended.

Here, the case where a deoxime-type condensation reaction type silicone rubber-based material is used as the silicone rubber-based material 12 will be described in further detail without omitting duplication. The deoxime-type condensation reaction type silicone rubber-based material is composed of 100 parts by weight of an organopolysiloxane having hydroxyl groups at both molecular terminals, 50 to 500 equivalents of a crosslinking agent with respect to the hydroxyl groups, and a catalyst of 0.005 to 0.1. Parts by weight, filler 5
It is composed of 50 parts by weight and 0.5 to 10 parts by weight of a lubricant. In the present invention, both ends of the molecular chain have a hydroxyl group as a reactive functional group, and the average unit formula R _a SiO
_The organopolysiloxane represented by _{(4-a) / 2} (a is 1.90 to 2.05) is a main component. In the above formula, R is an alkyl group such as a methyl group, an ethyl group, or a propyl group; a cycloalkyl group such as a cyclohexyl group; an aryl group such as a phenyl group or a tolyl group; an alkenyl group such as a vinyl group or an allyl group; The same or different monovalent hydrocarbon groups selected from those in which part or all of the hydrogen atoms bonded to the atoms are replaced with halogen atoms, amino groups, epoxy groups, carboxyl groups, cyano groups, etc. Is preferably a methyl group. The average degree of polymerization of the organopolysiloxane is 3,000 or more, preferably 5,000 to 10,000. By increasing the average degree of polymerization of the organopolysiloxane to 3,000 or more, the amount of the filler added for shaping the silicone rubber-based material can be reduced, and the rubber elasticity is impaired. A cured product can be obtained. In addition, the amount of residual low-molecular-weight organopolysiloxane is reduced, so that the uncrosslinked material is less likely to bleed before curing, thereby preventing contamination of the adherend and the like.

A crosslinking agent is blended in order to condense and cure the organopolysiloxane. As a cross-linking agent, an organosilane having three or more ketoxime groups bonded to a silicon atom in one molecule or a mixture thereof is used. Specifically, tetrakis (methylethylketoxime) silane,
Methyl tris (methyl ethyl ketoxime) silane, methyl tris (acetone oxime) silane, vinyl tris (methyl ethyl ketoxime) silane, phenyl tris (methyl ethyl ketoxime) silane, methyl tris (diethyl ketoxime) silane, methyl tris (methyl propyl ketoxime) silane, etc. Particularly, methyl tris (methyl ethyl ketoxime) silane, vinyl tris (methyl ethyl ketoxime) silane, and phenyl tris (methyl ethyl ketoxime) silane are preferable from the viewpoint of appropriate crosslinking rate. Further, an organosilane having two ketoxime groups bonded to a silicon atom in one molecule, such as dimethylbis (methylethylketoxime) silane and methylvinylbis (methylethylketoxime) silane, is used in combination to adjust the crosslink density. Is also good. However, it is desirable that the weight ratio does not exceed 20% with respect to the crosslinking agent having three or more ketoxime groups in one molecule. If it exceeds 20%, physical properties tend to be reduced.

The compounding amount of the crosslinking agent is 50 to 500 equivalents to the hydroxyl group of the organopolysiloxane, and particularly preferably 150 to 500 equivalents.
~ 400 equivalents are preferred. If it is less than 50 equivalents, the moisture-proof storage stability tends to decrease, and if it exceeds 500 equivalents, the original curing reaction tends to be hindered.

In order to appropriately control the curing rate of the organopolysiloxane by condensation crosslinking, a catalyst is blended. Examples of the catalyst include organic acid salts such as tin octoate and tin octenoate, alkyltin compounds such as dibutyltin diureate and dibutyltin oleate, Ti (OR) ₄ (R
Is an organic titanium compound represented by an alkyl group such as ethyl, propyl, butyl, amyl, and hexyl), and amine acids such as dimethylhydroxylamine and ethylhydroxylamine. These are not limited to one type, and two or more types may be combined. The amount of the catalyst
For 100 parts by weight of the organopolysiloxane,
0.05 to 0.1 part by weight is preferred, and particularly 0.01 to 0.1 part by weight.
0.05 parts by weight is preferred. If the amount is less than 0.05 part by weight, the internal curing may be incomplete. If the amount is more than 0.1 part by weight, the moisture-proof storage property is reduced and the curing speed is likely to be increased. In addition, when an amine silane coupling material such as γ-aminopropyltriethoxysilane is used as an adhesion assistant described later, since these also have a catalytic effect, it is not necessary to add the above catalyst,
Alternatively, a very small amount may be added.

In order to impart strength, shapeability and the like to the organopolysiloxane, a filler is blended. Calcium carbonate,
Titanium oxide and the like can also be used, but silica-based fillers are preferred from the viewpoint of heat resistance and reinforcing effect. Silica-based fillers include fumed silica, wet silica, hydrophobic silica,
Quartz powder, diatomaceous earth and the like are mentioned, and fumed silica is particularly preferred. These silica-based fillers may be previously subjected to a surface treatment with chlorosilane, silazane or the like in order to improve dispersibility. The particle size of the silica-based filler is preferably 50 μm or less. If it is larger than 50 μm, the reinforcing effect tends to decrease. The amount of the filler is usually 5 to 100 parts by weight of the organopolysiloxane.
It is 50 parts by weight, preferably 10 to 30 parts by weight. When the amount is less than 5 parts by weight, sufficient strength and shapeability cannot be obtained, and when it exceeds 50 parts by weight, the organopolysiloxane composition becomes hard and workability deteriorates.

A lubricant is blended to enhance the dispersibility of the filler and obtain stable strength. Examples of the lubricant include dimethylsilicone oil, diphenylsilanediol, and hexamethyldisilazane each having a hydroxyl group at a terminal and having a low degree of polymerization of about 5 to 20. The compounding amount is 0.5 to 100 parts by weight of the organopolysiloxane.
10 parts by weight. If the amount is less than 0.5 parts by weight,
When the effect of improving dispersibility is not obtained and exceeds 10 parts by weight,
Strength decreases.

In the present invention, in addition to the above components, an adhesion aid,
A non-reinforcing filler, an inorganic pigment, an ultraviolet absorber, a fungicide, and the like may be appropriately blended. Examples of the adhesion auxiliary agent include silane coupling agents such as γ-aminopropyltriethoxysilane, vinyltrichlorosilane, vinyltriethoxysilane, γ-glycidoxypropyltrimethoxysilane, isopropylisostearoyl titanate, and isopropyltri (N- Aminoethyl-aminoethyl) titanate,
Titanate coupling agents such as tetraoctylbis [(ditridecyl) phosphite] titanate can be used, and the amount thereof is preferably 2.0 parts by weight or less based on 100 parts by weight of the organopolysiloxane.

The sealing material 10 is formed in a continuous tape shape that has been cut in advance to the length of the side of the netted glass or has been wound up. And the sealing material 10
It is stored in a sealed container or stored at a low temperature, and is taken out of the container at the construction site.

8 mm).

Next, a method for sealing the netted glass 1 using the sealing material 10 will be described. First,
The sealing material 10 is temporarily bonded to the cut surface of the netted glass 1 (the surface where the wire 2 is exposed). Here, the silicone rubber-based material 12 itself is adhered by the adhesive property. The silicone rubber-based material 12 is clay-like, but is attached on the aluminum tape 11,

Subsequently, as shown in FIG. 3, the sealing material 10 is pressed against the netted glass 1 using a jig 20. That is, the edge of the meshed glass 1 is inserted into the engagement portion 22a of the pressure roller 22, and the pressure roller 22 is rolled along the edge of the glass 1. As a result, the protruding portion 12a of the sealing material 10 is crushed by the bottom portion (arc-shaped cross section) of the engaging portion 22a of the pressure roller 22 so as to cover the cut surface of the netted glass 1 and the exposed wire.

Further, both ends of the sealing material 10 (thickness L

After this sealing, the silicone rubber-based material 12 is cured. For example, silicone rubber-based material 1
