作業が煩雑になっている。However, if the paper or polypropylene adhesive tape used for Murayama is mixed in during the recycling process, the performance of the polystyrene will be affected as an impurity since paper and polypropylene are not compatible with polystyrene, resulting in the production of high-quality recycled polystyrene. There is a problem that it cannot be done. Therefore, in order to recycle high-quality polystyrene, all of the adhesive tape used in Murayama must be removed from the expanded polystyrene box.
Work has become complicated.
又、ポリプロピレン製粘着テープは手で切れないために
鋏やテープ用力・ツタ−を使用する必要が有り、作業効

リスチレンに対し影響の少ない溶剤を選択し更にこれを
塗布後瞬時に乾燥させることでポリスチレン系粘着テー
プの製造を可能にしたものである。Conventionally, when trying to apply a silicone mold release agent to a polystyrene film, the polystyrene film was dissolved by the solvent in which the mold release agent was dispersed, such as xylene or l-luene, so adhesive tape for the polystyrene film was used. was considered impossible to manufacture. In the present invention, a polystyrene adhesive tape can be manufactured by selecting a solvent that has little effect on polystyrene and drying it instantly after coating.

剤を除去（乾燥）させることが必要であり、好ましくは
３秒以内である。溶剤除去はシリコーンが離型剤として
仕分な程度に硬化した時点をもって完了したものとする
。In the present invention, it is necessary to remove (dry) the solvent immediately after applying the release agent to the film, preferably within 3 seconds. Solvent removal is considered complete when the silicone has hardened to a degree suitable for use as a mold release agent.

溶剤５００〜１５００重量部が好ましい。In the present invention, the amount of each component mixed and dispersed in the solvent is
3 parts by weight of platinum catalyst per 100 parts by weight of addition type silicone
~7 parts by weight, 6 to 14 parts by weight of an acetylene curing retarder,
500 to 1500 parts by weight of solvent is preferred.
離型剤の塗布量は上記成分の混合イ？ＨＯｍｇ／ｍ２〜

問題が百り、好ましくない。又、２ ｇ／ｍ２を超して
も効果が変わらな（なり、経済的に見て２ ｇ／ｍ２を
超える塗布量は不要である。Is the amount of mold release agent applied based on the mixture of the above components? HOmg/m2～
2 g/m2 is preferred. If the release agent is less than 50 mg/m2, the adhesive tape will have poor back-female properties, and
There are many problems such as the adhesive tape curling and becoming difficult to handle, which is not desirable. Moreover, even if the coating amount exceeds 2 g/m2, the effect remains unchanged (therefore, from an economical point of view, there is no need to apply a coating amount exceeding 2 g/m2).

粘着強度が不足するので好ましくない。The acrylic pressure-sensitive adhesive used in the present invention is preferably an emulsion type having a concentration of 40 to 65% by weight. For example, Cemedine (EMPS-30, EMPS-4 manufactured by ~)
0 is mentioned. The amount of coating on the polyethylene film J\ is 5 g/m2 or more, and if it is less than 5 g/m2, the adhesive strength will be insufficient, so it is not preferable.

。The specific manufacturing method for the polystyrene adhesive tape of the present invention is not particularly limited as long as the above manufacturing conditions are satisfied, but
Preferably, the mold release agent is applied while moving the polystyrene film at a constant speed, and at the same time, preferably 80%
It is preferable to dry it in a dryer at a temperature of ℃ for 2 seconds.
