Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to aluminized glass cloth. More specifically, the present invention relates to a glass cloth having a metallic aluminum vapor deposited layer with metallic luster.

BACKGROUND OF THE INVENTION It is difficult to obtain an aluminum deposited film with good adhesion by directly depositing aluminum on a glass cloth. Therefore, in order to obtain a glass cloth having an aluminum vapor-deposited layer on its surface, aluminum may be vapor-deposited on the glass cloth after the surface is coated with a resin or the like, or aluminum may be vapor-deposited on a plastic film such as polyester. It is also done by gluing it to glass cloth. However, by such methods, it is not possible to obtain a metallic-like aluminum vapor deposited film having sufficient metallic luster, and furthermore, in the latter case, there are also disadvantages such as impairing the original air permeability of the glass cloth.

OBJECTS OF THE INVENTION An object of the present invention is to provide a glass cloth having an aluminum vapor-deposited layer on its surface having sufficient adhesive strength and metallic luster, and also having a predetermined air permeability.

Structure of the Invention According to the present invention, an aluminum vapor-deposited glass cloth is provided, which is a glass cloth made of glass fibers, provided with a resin layer containing a pigment on one or both sides, and further provided with an aluminum vapor-deposited layer thereon. It is something that has been established.

Detailed Description of the Structure of the Invention The aluminum-deposited glass cloth according to the present invention is shown in Example t?
[', In a resin bath in which a pigment is homogeneously mixed with an emulsion of a resin such as polyvinyl chloride, ethylene-vinyl acetate copolymer, polyvinyl acetate, or polyester, or a solution of a resin such as water-soluble melamine or epoxy, or a mixture thereof. It is obtained by dipping a glass cloth, squeezing it appropriately, drying it, coating the glass fiber surface of the glass cloth with a colored resin layer, and then performing aluminum vapor deposition by a conventional method.

When such a KM material is not present in the resin layer.

The aluminum vapor deposited layer appears matte gray and does not become a metallic layer with metallic luster. However, when a pigment is present in this resin layer, it is possible to provide a metallic aluminum vapor deposited layer having a desired metallic luster. For such purposes, copper phthalocyanine blue is recommended.

Chlorinated a color m phthalocyanine, permanent carmine F
Organic pigments such as B, pyrazolone red, bensolane yellow 5G, carbon black, and aniline black, as well as inorganic pigments such as chrome yellow, molybdenum orange, and ultramarine glue, can all be used. In particular, such chromatic pigments are preferable because they give the aluminum deposited layer a strong metallic luster surface. Further, among these pigments, a pigment whose black color imparts a yellow-green color to the resin layer is particularly preferable from the viewpoint of gloss.

The presence of these pigments in the resin layer causes unevenness in the resin film due to the presence of the pigment particles, and as a result, the surface area of the resin layer increases and the adhesion of the aluminum vapor-deposited film is completely improved. Furthermore, when a resin layer containing pigments is formed on both sides of the glass cloth and an aluminum vapor-deposited layer is formed on one side, one side has a chromatic surface and the other side has a metallic-like yellow surface. You can also get unique glass cloth.

Note that the glass cloth used in the present invention may be made of ordinary glass fiber. Such glass fibers are now well known and are used as an important industrial material in a wide range of applications such as reinforcing plastics, curtain cloths, table cloths, and insect nets.

In the present invention, such glass cloth may be cloth-like, mat-like, net-like, or mesh-like.

The amount of resin to be coated is not particularly limited.

In order to completely cover the surface of the glass fiber, it is necessary that the amount is present in an amount of IX or more based on the weight of the glass, and it is preferably 5% or more.

The aluminum deposited layer can be applied by conventional vacuum deposition methods. The thickness of this layer is suitably between 200 and 800 Å, and more preferably between 40 and 500 Å.
IEt L. If it is thinner than 200 A, the reflectance will be poor, and conversely, even if it is made thicker by 800 A, no particular improvement will be seen in the reflection effect, and this will only be economically disadvantageous.

The glass cloth of the present invention having the above structure has not been found in conventional products.

Aluminum deposited surface gold with excellent metallic luster,
This aluminum vapor deposited layer also has good adhesion.

Therefore, the glass cloth according to the present invention can be used for curtains, blinds, etc.

It can provide insulation, heat retention, and cold retention effects. Furthermore, since it has an electromagnetic wave shielding effect, it can also be used for shielding harmful electromagnetic waves from electronic components and for use in loose antennas. Moreover, by using it as a carpet base fabric, a static electricity removal effect is added, and this becomes even more effective by applying an electrically conductive substance such as Kagen as a pigment in the resin layer.

In addition, conventional techniques such as bonding aluminum-deposited plastic films to glass cloth cannot be applied to mesh-like glass cloth, and even if applied to ordinary glass cloth, breathability cannot be maintained. Can not. Also, the presence of the film impairs the inherent heat resistance of the glass cloth, resulting in poor flame resistance. However, the glass cloth according to the present invention has the advantage that such drawbacks are less likely to occur.

Example The present invention will be further explained below with reference to Examples.
