成物を原料とするフィルムが使用され始めている。2. Description of the Related Art Heretofore, a film made of a resin composition containing a halogenated vinyl resin such as polyvinyl chloride has been used as a flame-retardant adhesive tape for bundling automobile electric wires. Such vinyl halide resin films generate harmful gases when incinerated. Therefore, recently, a non-halogen resin composition containing a large amount of an inorganic flame retardant such as magnesium hydroxide in a polyolefin resin is used as a raw material. Films have begun to be used.

め可塑剤を含有させることが技術常識とされていた。[0003] In an adhesive tape in which an adhesive layer is provided on a film made of a resin composition containing a vinyl halide resin, the tackiness of the adhesive tape is reduced by utilizing the softening effect of the transfer of the plasticizer from the film to the adhesive layer. Although it was ensured, in a film made of a non-halogen resin composition as a raw material, it was considered common technical knowledge that a plasticizer was previously contained in the adhesive layer because there was no transfer of the plasticizer from the film to the adhesive layer.

樹脂組成物が用いられてきた。A non-halogen adhesive tape using such a film is 100 parts by weight of a polyolefin resin such as ethylene-ethyl acrylate copolymer (hereinafter referred to as "EEA") and 100 parts by weight of an inorganic flame retardant such as magnesium hydroxide. A non-halogen resin composition comprising a non-halogen resin composition is formed into a film by an inflation method or the like, and the film is slit into a tape. On the surface of the tape, 100 parts by weight of an adhesive composition and 25 parts by weight of a plasticizer such as dioctyl phthalate are used. Has been manufactured by coating a mixture of the components dispersed uniformly. As the adhesive composition, for example, a resin composition comprising 50 parts by weight of natural rubber, 25 parts by weight of an acrylic adhesive, and 25 parts by weight of a tackifier adhesive has been used.

った。However, in order to produce such a halogen-free pressure-sensitive adhesive tape, a plasticizer must be blended with the pressure-sensitive adhesive composition and uniformly dispersed by stirring. However, there is a problem that it takes time to stir the pressure-sensitive adhesive composition containing the compound. In addition, when a plasticizer is added to such an adhesive composition, if this is an emulsion-type adhesive composition, the adhesive composition is dispersed, stirred, and then left for a while to obtain emulsion particles constituting the adhesive composition. There was a problem that the viscosity of the pressure-sensitive adhesive composition was rapidly increased due to the instability caused by the plasticizer, which made it difficult to control the viscosity.

Contrary to conventional technical common knowledge, a non-halogen resin composition comprising 100 parts by weight of a polyolefin resin and 60 to 150 parts by weight of an inorganic flame retardant contains 3 to 5 parts by weight of a plasticizer as a raw material. When using the film as the base material of the adhesive tape,
In addition, they have found that a pressure-sensitive adhesive tape having sufficient tackiness and tackiness can be obtained without previously containing a plasticizer in the pressure-sensitive adhesive layer, thereby completing the present invention.

A non-halogen resin composition, a film for an adhesive tape obtained by molding the same, and an adhesive tape can be provided. Therefore, according to the present invention,
There is no need to include a plasticizer in the pressure-sensitive adhesive composition as in the past, and therefore, the stirring time for uniformly dispersing the pressure-sensitive adhesive composition can be shortened, and viscosity control can be facilitated. it can. And since the pressure-sensitive adhesive tape according to the present invention has flame retardancy, it is useful for the production of automobiles, home electric appliances, mechanical products, and the like. Useful.
