巻きに使用される発泡性難燃テープ用組成物および発泡
性難燃テープに関するものである。Detailed description of the invention (Technical field to which the invention pertains) The present invention relates to a foamable flame-retardant composition and a foamable flame-retardant tape, and more particularly to a foamable flame-retardant composition and a foamable flame-retardant tape used for wrapping fire-resistant cables, flame-retardant cables, etc. The present invention relates to a flame-retardant tape composition and a foamable flame-retardant tape.

望されている。(Prior art) In recent years, there has been a strong demand for various facilities and structures to be made incombustible and flame retardant from the standpoint of disaster prevention, and in the field of electric wires and cables, there is a strong need to make them incombustible and flame retardant. However, there is a need for the development of fire-resistant cables that can withstand long-term use.
耐火ケーブルの耐火材料として大別すると、発泡性のも
のと非発泡性のものとがあり、薄く塗布するだけで熱伝
導を押さえる発泡性タイプのものが注目されている。Fireproof materials for fireproof cables can be roughly divided into foamable and non-foamable materials, and foamable materials are attracting attention because they suppress heat conduction by simply applying a thin layer.

ため収縮を起こしたり、脆くなって崩れてしまい、耐火
性が劣る欠点があった。However, nowadays, an ethylene-vinyl acetate copolymer emulsion containing a carbonization agent such as starch and a foaming layer forming agent such as ammonium phosphate as the main ingredients is applied to cotton cloth. In such conventional fire-resistant compositions, the carbide formed by heating tends to become brittle and scatter due to the force of the fire, and the base fabric itself has low heat resistance, causing it to shrink or become brittle and crumble, resulting in poor fire resistance. It had the disadvantage of being inferior.

One or more types of rubber and geothermal plastic elastomer such as R, NBR, EPM, EPDM, and IIR are used.

性組成物は難燃性が良好であるという利点がある反面、
燃焼してしまうと有毒なハロゲンガスを発生するという
欠点がある。このため本発明においては、ハロゲン元素
を含有しないポリマーを使用しているのである。Flame-retardant compositions made by adding halogen-based flame retardants to halogen-based polymers are known, but while such halogen-based flame-retardant compositions have the advantage of good flame retardancy,
The disadvantage is that when burned, it emits toxic halogen gas. Therefore, in the present invention, a polymer containing no halogen element is used.

効に使用できる。Conventionally, this type of foam layer forming agent can be effectively used as the foam layer forming agent added to such a binder. For example, one or more of ammonium phosphate, ammonium sulfate, ammonium sulfamate, melamine, urea, etc. can be effectively used.

性も極端に落ちてしまう。The foamed layer forming agent is added in an amount of 80 to 600 parts by weight per 100 parts by weight of the binder. If it is less than 80 parts by weight, there is a risk that a foamed layer will not be formed in the event of combustion, while if it exceeds 600 parts by weight, it will be difficult to process and the physical properties will be extremely poor.

などを有効に使用できる。As a carbonized layer forming agent for forming a carbonized layer together with such a foamed layer, a carbonized layer forming agent that has been conventionally used in this type of flame retardant composition can be effectively used. For example, carbohydrates such as starch and sucrose, and polyhydric alcohols such as hexitol and pentaerythritol can be effectively used.
この炭化層形成剤は結合剤１００重量部に対し３０〜２
００重量部添加されている。配合量が３０重量部未満で

00 parts by weight were added. If the amount is less than 30 parts by weight, a carbonized layer may not be formed in the event of combustion, while if it exceeds 200 parts by weight, processing may not be possible.

る。In the present invention, a metal hydrate is added to such a formulation. A foamable fireproof composition prepared by adding a foam layer forming agent, a carbonized layer forming agent, etc. to a binder as described above has the advantage that the composition has a large expansion ratio, but has the disadvantage that the foamed carbonized layer is somewhat brittle. However, it has been found that by adding a metal hydrate, a strong carbonized layer is formed, although the foaming ratio is slightly lowered.
このような金属水和物としては、例えば水酸化アルミニ
ウム、水酸化マグネシウム、ハイドロタルサイトなどの

。The amount of one or more metal hydrates is 10 to 500 parts by weight. If it is less than 10 parts by weight, the effect of reinforcing the carbonized layer may not be exhibited, and if it exceeds 500 parts by weight, the foaming ratio may become too low.

、加硫剤も加えることができる。It is also possible to add various additives to the flame retardant compositions as described above. For example, titanium dioxide, silica, carbon black, and various stabilizers can be added as fillers. Furthermore, when the binder is rubber, various accelerators and vulcanizing agents can also be added.

Flame retardant fibers such as acrylic fibers and ester fibers, cotton,
A foamable flame-retardant tape is made by gluing it to a flame-retardant base fabric such as rayon or other wood fiber and forming it into a tape.

、糊引きなどが困難になるからである。Using such a solvent, the concentration of the flame retardant composition is preferably 10 to 50%, and the flame retardant composition is applied onto the base fabric by means such as gluing. If the concentration of the flame retardant composition is less than 10%, the viscosity will be too low and machining will be difficult;
It has the disadvantage that it oozes through the base fabric. On the other hand, if the concentration of the flame retardant composition exceeds 50%, the viscosity becomes high, making it difficult to apply glue.

である。If it is less than 30 g/m2, the flame-retardant layer of the tape may be too thin, while if it exceeds 150 g/m2, the flame-retardant layer may become too thick, making it inconvenient to remove.

This is because if the thickness exceeds 1 mm, handling may become inconvenient.
