熱軟化点の低い、無定形の樹脂質である。Examples of tackifiers used in adhesive tapes include modified rosins, rosin readers, polyterpene resins, indene resins, and phenol-modified Roman-indene resins. Most of them are amorphous resins with a molecular weight of about 200 to 1,500 and a relatively low thermal softening point.
これら粘着性付与剤に充填剤などを添加し、これを基材

（発明が解決しようとする課題）
上述したような粘着テープは、通常の生活用品などに使
用する場合は特に問題はないのであるるが、たとえば、
原子力発電所で使用される配管などのＳＵＳ （ステン
レス鋼）製品を保護するための保護シートを止めるため
に粘着テープを使用する場合、幾つかの問題が生じる。(Problems to be Solved by the Invention) Adhesive tapes as described above pose no particular problems when used for ordinary household goods, etc.
Several problems arise when using adhesive tape to fasten protective sheets for protecting SUS (stainless steel) products such as piping used in nuclear power plants.
まず、ＳＵＳ製品の保護シートは運転開始から数か月以

業中における溶接などで火花が粘着テープに飛び、延焼
を引きおこすという問題がある。First, the protective sheet for SUS products is kept on for several months after the start of operation, and there is a problem in that sparks from welding during piping assembly work can fly onto the adhesive tape, causing the spread of fire.
また、粘着テープの不透明さによって配管表面の刻印が
被覆され、視認性に劣ることも問題である。Another problem is that the opacity of the adhesive tape covers the markings on the surface of the pipe, resulting in poor visibility.

。Furthermore, if sticky tape contains halogen, it will not only be harmful to the human body as it will generate hydrogen halide gas in the event of a fire, but it will also corrode SUS products. tape is desired.
すなわち、透明性を備え、かつ防災効果の高い粘着テー
プを得ることが課題となっている。In other words, it is a challenge to obtain an adhesive tape that is transparent and has a high disaster prevention effect.
本発明はこのような課題を解決するためになされたもの
で、難燃性と透明性とを兼ね備え、かつ非ハロゲン系の
粘着テープを提供することを目的とする。The present invention was made to solve these problems, and an object of the present invention is to provide a non-halogen adhesive tape that has both flame retardancy and transparency.
［発明の構成］

ＢＯｍ二％以上含有することを特徴としている。[Structure of the Invention] (Means for Solving the Problems) The adhesive tape of the present invention is an adhesive tape in which an adhesive is coated on a base film via a binder, and the U material film is made of polybutylene terephthalate. The binder is characterized in that it contains modified ethylene methyl acrylate in an amount of 2% or more of BOm.

水素反応によって得ることができる。Polybutylene terephthalate has terephthalic acid and 1.4
- a polyester produced by polycondensation of butanediol,
It can be obtained by a transesterification reaction of dimethyl terephthalate and excess 1,4-butanediol by heating, or by a dehydrochlorination reaction of dimethyl terephthalate and 1,4-butanediol.
これをフィルムとするには、溶融紡糸法の原理に従って
、ポリマーの融点よりやや高温で融解して細い溝から押
し出し、直ちに水中で急冷して無定形のまま固化させ、
次に縦横両方向に延伸して分子配列を整えて結晶化させ
る方法などが挙げられる。In order to make this into a film, according to the principles of the melt spinning method, it is melted at a temperature slightly higher than the melting point of the polymer, extruded through a narrow groove, immediately quenched in water, and solidified in an amorphous form.
Next, examples include a method of stretching in both the vertical and horizontal directions to adjust the molecular arrangement and crystallize it.
粘着テープの基材として、ポリブチレンテレフタレート
フィルムの厚さはｌＯ〜５００μ−が好ましい。As the base material for the adhesive tape, the thickness of the polybutylene terephthalate film is preferably 10 to 500 μ-.
なぜなら、ＩＯμｎ以下であると薄くなりすぎて強度が
低下し、５００μ蒙を超えた厚さでは柔軟性に欠け、作
業性も低下するためである。This is because if the thickness is less than IO μm, it becomes too thin and the strength decreases, and if the thickness exceeds 500 μm, it lacks flexibility and reduces workability.
