したものは、基材そのものの柔軟性が乏しく、伸びが小
さい。エポキシ樹脂含浸粘着テープはエポキシ樹脂が硬
化するので基材の柔軟性が乏しい。The materials using the above-mentioned Japanese paper or cloth as a base material have a poor flexibility of the base material itself and a small elongation. The epoxy resin-impregnated adhesive tape has a poor flexibility of the base material because the epoxy resin is cured.

ングの目的を達することができない。Therefore, when it is used on a curved line for masking at a construction site or painting on an automobile, or when it is used for sealing corrugated cardboard, etc., the adhesive tape does not fit in a curved line or a crease, and it is adhered for masking. There is a gap between the body and the adhesive tape, and the paint flows from there, making it impossible to achieve the purpose of masking.

あるのが好ましい。In order for the pressure-sensitive adhesive tape to easily fit to the curved adherend surface, the flexibility and proper elongation of the substrate are required. In the present invention, a non-woven fabric having a basis weight of 5 to 50 g / m 2 or a non-woven fabric produced by the spunbond method and heated and compressed is used in order to give the substrate sufficient flexibility. The diameter of the yarns constituting the non-woven fabric is preferably about 1.5-5 μm.

とにより基材の厚さを薄くして、厚みの薄い粘着テープ
とすることができる。Of these, the method (1) is the simplest and most practical. In this case, the entire surface of the non-woven fabric may be uniformly heated and compressed, but the heating and compression area can be freely changed by, for example, making the heating and compression part into a number of dots, stripes, etc., and thereby adjusting the elongation. You can By heating and compressing the non-woven fabric, the thickness of the base material can be reduced to obtain a thin adhesive tape.

る。The lower the ratio of the heated and compressed area to the area of the non-woven fabric, the more flexible the substrate is, but the greater the elongation. Therefore, the heat compression area needs to be at least 15% or more, preferably 20% or more. The heating and compression area of the non-woven fabric is for architectural coating,
About 20-30% for electrical insulation, 25 for sealing
28%, and 20-100% for vehicle coating is suitable.
【００２０】しかし、上記だけでは伸びの調整が不充

Hand tearability is affected by fiber basis weight and fiber alignment. The higher the basis weight of the fiber, the worse the hand-cutting property. Therefore, in order to obtain good hand-cutting property, the basis weight is preferably about 15 g / m 2 or less.

間隔をおいてミシン目を設けるのがよい。The closer the fiber aspect ratio is to 1: 1, the more flexible it is and the better the hand-cutting property, but it is difficult to use because it stretches when sticking an adhesive tape or rewinding. However, as the aspect ratio of the aspect ratio becomes larger, the hand-cutting property becomes worse and the flexibility becomes poor. Therefore, the aspect ratio is preferably in the range of 8: 1 to 1: 1. When the ratio of lengths is large, it is preferable to provide perforations at appropriate intervals in the width direction of the adhesive tape in order to compensate for the hand-cutting property.

Since peeling is likely to occur due to poor adhesion, it is preferable to use an extrusion laminating method in which these resins are extruded and laminated in a molten state because the lamination strength is high and curling does not occur. Since the hand-cutting property is deteriorated by providing the sealing layer, it is preferable that the perforation for imparting the hand-cutting property is provided after laminating the sealing layer. A release agent is applied to the filling layer, if necessary.

好ましい。As the pressure-sensitive adhesive of the pressure-sensitive adhesive tape of the present invention, conventionally known ones such as natural rubber, synthetic rubber rubber-based pressure-sensitive adhesive and acrylic pressure-sensitive adhesive can be used. Further, these pressure-sensitive adhesives can be used in either solvent type or emulsion type. In order to enhance the anchor effect of the pressure-sensitive adhesive and to impregnate a part of the pressure-sensitive adhesive into the base material for the purpose of adjusting the elongation of the base material, it is preferable to use a roll coater such as a reverse roll or a two-roll coating method.

In addition, the thickness of the portion to be impregnated into the substrate should be more than half of the coating thickness,
It is preferably -80%. When the pressure-sensitive adhesive impregnated in the base material is dried, it binds to the fibers and the intersections of the fibers to suppress the elongation of the base material. Further, since the volume shrinks as the solvent evaporates, the pressure-sensitive adhesive tape is further thinned.

By increasing the ratio of the pressure-sensitive adhesive with which the base material is impregnated in this way, elongation can be suppressed and adjusted. Further, by impregnating the base material, the thickness of the pressure-sensitive adhesive layer on the surface of the base material becomes thin, whereby generation of side sticks can be suppressed, which is more desirable.

ープを得ることができる。The adhesive tape of the present invention has a basis weight of 5 to 50 g.
/ M 2 non-woven fabric, or the non-woven fabric produced by the spunbond method and heated and compressed is used as the base material, so that it is highly flexible, and even if the adherend is a curved surface, the adhesive tape and the adherend There is no gap between them and wrinkles.
Since the pressure-sensitive adhesive tape is thin, it is not necessary to apply the pressure-sensitive adhesive thickly as in the conventional case, and it is possible to obtain a long-winding pressure-sensitive adhesive tape. Also, since the sealing layer is laminated on one side, it can be applied straight without sticking when applied in a straight line, and can be applied to both curved and linear adherends. It is particularly preferably used as a masking material for painting or vehicle painting, a sealing material, an electric insulating tape, and a packaging material. Further, since the base material is impregnated with more than half of the thickness of the pressure-sensitive adhesive applied to the base material surface, the elongation and the hand tearability are adjusted while maintaining the required flexibility of the base material. Further, the thickness of the nonwoven fabric is further reduced due to the shrinkage of the impregnated pressure-sensitive adhesive due to drying, and it can be applied to various uses.
Furthermore, since the thickness of the pressure-sensitive adhesive layer on the surface becomes thin, side sticks do not occur even when wound in a roll. As a result of the above, the pressure-sensitive adhesive tape of the present invention has a performance higher than that of the conventional product, but the total thickness of the pressure-sensitive adhesive tape can be made thinner than that of the conventional product, so that the winding length is increased even if the winding diameter is the same as that of the conventional product. be able to. According to the method for producing an adhesive tape of the present invention, since the nonwoven fabric is heated and pressed, the elongation of the base material is small,
In addition, it can be made thin, and since the sealing layer is laminated thereon by extrusion laminating, a base material having a large lamination strength between the sealing layer and the nonwoven fabric and having no curl can be obtained. Furthermore,
Since the substrate is impregnated with more than half of the thickness of the applied pressure-sensitive adhesive, the pressure-sensitive adhesive tape having low elongation, good tearability by hand, and thin thickness can be obtained.
