を損ないやすいという欠点があった。However, in this method, when the thickness of the base material is large, there is a disadvantage that it is difficult to obtain the flame retardancy of the entire tape when the flame retardant of the adhesive alone is used, and also that the flame retardant added to the adhesive tends to impair the adhesive properties. was there.
本発明は、粘着剤に難燃剤を添加することなく粘着特
性を保持し、かつ優れた難燃性を有する粘着テープを提
供することを目的としている。An object of the present invention is to provide a pressure-sensitive adhesive tape that retains pressure-sensitive adhesive properties without adding a flame retardant to the pressure-sensitive adhesive and has excellent flame retardancy.

ープにある。(Means for Solving the Problems) In order to achieve the above object, in the pressure-sensitive adhesive tape of the present invention, a specific flame retardant layer is interposed in a tape base material. A polyester film 1, 1 is laminated on a tape substrate 3 laminated via an adhesive layer 2 containing 60 to 400% by weight of a powdery flame retardant, and a pressure-sensitive adhesive 4 is applied to a flame-retardant pressure-sensitive adhesive tape. is there.
以下、本発明を図面により説明する。 Hereinafter, the present invention will be described with reference to the drawings.

The tape base material 3 according to the present invention is a laminate in which a specific adhesive layer 2 is interposed between the polyester films 1 and 1, and a normal non-stretched or stretched film can be used as the polyester film. ~Ten
Those having a range of 0 μm can be suitably used.

レン−酢酸ビニル系等各種組成のものが使用できる。It is necessary to use an adhesive layer 2 containing 60 to 400% by weight of a powdery flame retardant. As the adhesive, a solventless hot-melt adhesive or a reaction-curable adhesive can be preferably used. Those having various compositions such as epoxy, urethane, polyester, and ethylene-vinyl acetate can be used.

ものでは接着剤の特性を阻害し易いという問題がある。As powdery flame retardants, tetrabromophthalimide,
Halogen-containing organic compounds such as tetrabromophthalic anhydride, decabromodiphenyl ether and antimony trioxide;
Examples include inorganic compounds such as aluminum hydroxide and the like, which can be used in appropriate combination. Here, if a non-powder flame retardant such as a liquid flame retardant is used, the interlayer adhesion of the adhesive is easily reduced, which is inconvenient. When the content of the powdery flame retardant is less than 60% by weight, the flame retardancy is not improved, and when the content exceeds 400% by weight, there is a problem that the properties of the adhesive are easily hindered.
接着剤層の厚みはプラスチックフイルムの総厚みに対
し、20％乃至同等の範囲とすればよく、この厚みが20％
未満では難燃性が不十分であり、同等を越えるものでは
接着剤をフイルム上に塗布することが困難になり易い。The thickness of the adhesive layer may be in the range of 20% or more to the total thickness of the plastic film, and this thickness is 20%.
When the amount is less than the above, the flame retardancy is insufficient, and when the amount exceeds the equivalent, it becomes difficult to apply the adhesive on the film.

剤、酸化防止剤等を適宜添加することができる。Note that a normal back surface treatment agent may be provided on one side surface (opposite surface of the pressure-sensitive adhesive applied surface) of the base material 3 as necessary. The pressure-sensitive adhesive 4 is applied to the tape base having the above-mentioned configuration, and the pressure-sensitive adhesive mainly includes natural rubber, synthetic isoprene rubber, styrene-butadiene rubber, styrene-isoprene-styrene block copolymer, acryl-silicon, and the like. The composition is used, and a tackifying resin, a softening agent, an antioxidant and the like can be added as needed.

化できて好ましい。An ordinary flame retardant may be further added to the pressure-sensitive adhesive within a range that does not lower the pressure-sensitive adhesive properties. The coating thickness of the adhesive 4 is 10
It may be applied in a range of about 50 μm. If it is less than 10 μm, the adhesive strength is insufficient, and if it exceeds 50 μm, the flame retardancy tends to decrease. Although various methods are conceivable as a method for producing the pressure-sensitive adhesive tape of the present invention, a method in which a tape base material is first laminated and then a pressure-sensitive adhesive is applied is preferred because the process can be simplified.
