Description of the Related Art Generally, when a plurality of polyvinyl chloride wires are bundled in one place, the polyvinyl chloride wires having insulating properties are provided so that the bundled polyvinyl chloride wires are not damaged and current is leaked. An adhesive tape made of vinyl resin using a resin as a base material is used. When a covered electric wire such as a polyvinyl chloride electric wire or a cable is connected on the way, the connecting portion is insulated so as not to cause a short circuit or the like at the connecting portion. In order to maintain the insulation of the connection, an adhesive tape is wrapped around the connection to ensure insulation and mechanical strength of the connection. As the adhesive tape, a PVC (polyvinyl chloride) -based adhesive tape using a polyvinyl chloride resin having an insulating property as a support is used.

る。The adhesive force of the adhesive applied on one side of the substrate of the adhesive tape made of polyvinyl chloride resin thus produced increases the thickness of the applied adhesive. Adhesive strength also increases, but when the applied thickness of the adhesive exceeds a certain value, the adhesive strength is almost flat, and even if the applied thickness of the adhesive is further increased, it does not improve much. is there. In addition, even if the pressure-sensitive adhesive applied to one side of the substrate is appropriate, the pressure-sensitive adhesive tape made of polyvinyl chloride resin, after applying the adhesive to one side of the polyvinyl chloride resin base, The adhesive strength is not stable unless heat aging is performed at a predetermined temperature for a predetermined time.

いことに基づくものである。Further, the tack as the adhesive strength of the adhesive layer of the adhesive tape is such that a part of the plasticizer in the support of the polyvinyl chloride resin is transferred into the adhesive by the heat aging of the adhesive tape, and the adhesive tape is supported. This is improved by balancing the amount of the plasticizer contained in the body with the amount of the plasticizer transferred into the pressure-sensitive adhesive. Therefore, even if the thickness of the adhesive applied to one side of the support is appropriate, after applying the adhesive to one side of the polyvinyl chloride resin support, heat aging is performed at a predetermined temperature for a predetermined time. If the adhesive strength is not stable without performing, the adhesive tape must be thermally aged and a part of the plasticizer in the support of the soft polyvinyl chloride resin containing the plasticizer must be transferred to the adhesive. The reason is that the amount of the plasticizer in the support of the pressure-sensitive adhesive tape is not balanced with the amount of the plasticizer in the pressure-sensitive adhesive.

低下は免れない。[0008] For this reason, in the production of a vinyl chloride-based pressure-sensitive adhesive tape using a polyvinyl chloride resin softened by the addition of a plasticizer, a part of the plasticizer necessary for the support (substrate) is converted into a pressure-sensitive adhesive solution. However, in this method, the amount of the plasticizer added is substantially the same as the method in which the entire amount of the plasticizer is added to the support, and a decrease in the adhesive strength of the adhesive is inevitable.

も、粘着剤の粘着力が著しく低下すると問題がある。When the plasticizer is added to the support of the pressure-sensitive adhesive tape in the entire amount required by the support, the plasticizer incorporated in the support migrates to the pressure-sensitive adhesive layer over time, and the adhesive force of the pressure-sensitive adhesive is significantly reduced. Even in the method of mixing a part of the plasticizer required for the support of the pressure-sensitive adhesive tape into the pressure-sensitive adhesive solution, there is a problem that the pressure-sensitive adhesive strength is significantly reduced.

It is the result of performing an adhesive tape 180 ° peel test according to “0237”. That is, a test piece (25 mm × about 250 mm) of an adhesive tape was placed on a specified stainless steel plate with a 2 kg roller 1.
The above 180 ° peel test was carried out 20 minutes after the application and the application by reciprocating pressure bonding. The same test was performed after the adhesive tape was left in a thermostat at about 60 ° C. for 7 days to promote aging.

The weight was measured. The plasticizer transferability (%) is determined by the following formula: plasticizer transferability (weight reduction ratio) = (weight before heating−weight after heating) / weight before heating × 100. The smaller the value of the plasticizer transferability (weight loss rate), the smaller the amount of the plasticizer in the adhesive layer. Further, the hardness in Tables 1 and 2 is based on JIS K
