ている。2. Description of the Related Art Conventionally, a film formed by molding a resin composition containing a vinyl halide resin such as polyvinyl chloride as a base material of a flame-retardant pressure-sensitive adhesive tape for tying automobile electric wires by a calender method or the like. Has been used. However, vinyl halide resins generate harmful gases when incinerated. Therefore, recently, polyethylene, polypropylene, ethylene-methyl acrylate copolymer (EEA), and ethylene-vinyl acetate copolymer (ENA) have been used.
Films obtained by forming a non-halogen polyolefin resin composition containing a large amount of an inorganic flame retardant such as magnesium hydroxide in a polyolefin resin such as magnesium hydroxide by an inflation method or the like have begun to be used as a base material of an adhesive tape.

A tackifier comprising a group petroleum resin or the like, and a pressure-sensitive adhesive composition containing a phenolic antioxidant are coated.

粘着組成物に添加されている。In an adhesive tape based on a vinyl halide resin film, the plasticizer contained in the film migrates to the adhesive composition layer coated on the film and acts as a softening agent. Tackability is ensured. In a pressure-sensitive adhesive tape having a film formed from a non-halogen polyolefin-based resin composition as a base film, a so-called non-halogen pressure-sensitive adhesive tape, the plasticizer does not migrate from the base film to the pressure-sensitive adhesive composition layer. It has been added to the composition.

あった。However, when a plasticizer is added to the pressure-sensitive adhesive composition for a halogen-free tape, if the pressure-sensitive adhesive composition is an emulsion-type pressure-sensitive adhesive composition, the pressure-sensitive adhesive composition is dispersed, stirred, and left for a while. Then
The emulsion particles constituting the pressure-sensitive adhesive composition are destabilized by being violated by the plasticizer, and as a result, the viscosity of the pressure-sensitive adhesive composition increases, making it difficult to control the viscosity.

して１０〜５０重量部であることが好ましい。In the present invention, the plasticizer is microencapsulated, and 10 to 10 parts by weight of the base resin is added.
Since 50 parts by weight are included, direct contact between the emulsion particles of the base resin is eliminated, and therefore, the emulsion particles of the base resin are violated by the plasticizer over time after dispersion and stirring of the non-halogen tape adhesive composition. Disappears. Therefore, the viscosity stability of the pressure-sensitive adhesive composition for a non-halogen tape of the present invention is improved. Also, in the present invention, the content of the microencapsulated plasticizer,
The content is 10 to 50 parts by weight with respect to 100 parts by weight of the base resin. If the content of the plasticizer is less than 10 parts by weight, the initial tackiness (tack property) is insufficient, and it is difficult to adhere to the adherend. Therefore, it is preferable that the content of the plasticizer is 10 to 50 parts by weight based on 100 parts by weight of the base resin.
