Description of the Related Art Conventionally, as a double-sided pressure-sensitive adhesive tape, one in which a pressure-sensitive adhesive layer made of a pressure-sensitive adhesive such as an acrylic pressure-sensitive adhesive is laminated on both surfaces of a non-woven fabric substrate made of rayon and / or pulp has been widely used. On the other hand, the double-sided pressure-sensitive adhesive tape is used for various purposes, but in some cases, it may be used in a high temperature atmosphere exceeding 100 ° C. In the double-sided pressure-sensitive adhesive tape used under such a high temperature environment, a pressure-sensitive adhesive having excellent heat resistance is used as a pressure-sensitive adhesive forming the pressure-sensitive adhesive layer.

ていた。However, in the conventional double-sided pressure-sensitive adhesive tape, since the base material is composed of a non-woven fabric base material made of rayon and / or pulp, 120 ° C. to 140 ° C.
If left in an atmosphere of a certain degree, carbonization of the base material proceeds,
There is a problem that the strength of the base material is significantly reduced. Therefore, as a double-sided pressure-sensitive adhesive tape suitable for heat-resistant use, one using a substrate made of glass fiber has been proposed. However, when a base material made of a glass base material is used, there is a problem that the thickness of the base material is increased, flexibility is lowered, and cost is very high. Therefore, the double-sided pressure-sensitive adhesive tape using glass fiber as a base material is excellent in heat resistance, but its use is significantly limited.

The reason why the non-woven fabric base material containing polyester as the main component is used is to increase heat resistance, and the use of the non-woven fabric base material containing polyester as the main component lowers the mechanical strength in a high temperature atmosphere exceeding 100 ° C. Can be prevented. The non-woven fabric substrate containing polyester as the main component that can be used may be made of only polyester, or may contain rayon, pulp, vinylon or the like as an accessory component in addition to polyester. However, in order to exert sufficient heat resistance, the polyester content must be 50% by weight or more. The non-woven fabric base material containing polyester as a main component is preferably 8 to
A grammage of about 24 g / cm 2 is used.

じ難い。The non-woven fabric containing polyester as the main component has excellent heat resistance as described above, and does not cause carbonization or the like even when placed in an atmosphere exceeding 100 ° C., and also has a reduced mechanical strength. Hard to happen. Further, the non-woven fabric substrate containing polyester as a main component is also superior in flexibility as compared with the non-woven fabric substrate made of glass fiber. In the double-sided pressure-sensitive adhesive tape of the present invention, a pressure-sensitive adhesive layer having a heat-resistant holding power of 100 ° C. or higher is formed on both sides of the above-mentioned nonwoven fabric base material mainly composed of polyester having excellent heat resistance and flexibility.
Even if it is placed in an atmosphere exceeding 00 ° C, or used in an atmosphere exceeding 100 ° C, and the load is applied in either the vertical direction or the horizontal direction, it is possible to fully exhibit the characteristics of the adhesive. In addition, the adhesive strength is less likely to decrease.

いた従来の両面粘着テープに比べて著しく高められる。As described above, in the present invention, since the non-woven fabric base material containing polyester as the main component is used, the heat resistance can be enhanced without impairing the flexibility of the base material. In addition, since the pressure-sensitive adhesive layer is composed of an acrylic pressure-sensitive adhesive having a heat-resistant holding power of 100 ° C. or more on both surfaces of the non-woven fabric substrate having the improved heat resistance as described above, the pressure-sensitive adhesive force in a high temperature environment, particularly T type The peeling force is remarkably enhanced as compared with the conventional double-sided pressure-sensitive adhesive tape using a non-woven fabric substrate made of rayon, linen or the like.

た両面粘着テープを提供することができる。Further, when a non-woven fabric made of only polyester is used, it does not contain a binder resin, so that the impregnating property of the pressure-sensitive adhesive is good. Therefore, when the double-sided pressure-sensitive adhesive tape is constituted, the base material and the pressure-sensitive adhesive are used. The adhesion strength between the layers can be increased. Similarly, since the pressure-sensitive adhesive has an excellent impregnating property, it is possible to provide a double-sided pressure-sensitive adhesive tape having excellent suitability for various punching processes.
