【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、被着体に接着された接着フィルム（シー
ト）の剥離に用いるフィルム剥離剤に関するもので、接
着剤（粘着剤）を被着体に残すことなく接着フィルムを
被着体から容易に剥離することができるフィルム剥離剤
に関するものである。TECHNICAL FIELD The present invention relates to a film release agent used for releasing an adhesive film (sheet) adhered to an adherend, and an adhesive agent (adhesive) applied to the film release agent. The present invention relates to a film release agent that can easily release an adhesive film from an adherend without leaving it on the body.
マーキィングフィルム等の接着フィルムは、広告用ス
テッカー、交通標識、道路標識、案内板、広告看板、コ
ンテナー類等の被着体に接着して使用されている。Adhesive films such as marking films are used by being adhered to adherends such as advertising stickers, traffic signs, road signs, guide boards, advertising signs, and containers.
而して、上記の如き接着フィルムを貼り変える場合等
においては、上記接着フィルムを剥離する必要がある
が、従来、この剥離は、ヘラ（スクレーパー）等で接着
フィルムを掻き取る方法、溶剤で接着フィルムを溶かし
て拭い去る方法、溶剤で接着フィルムを膨潤させて剥ぎ
取る方法等の方法で行われている。Thus, in the case of reattaching the adhesive film as described above, it is necessary to peel off the adhesive film. Conventionally, this peeling is performed by scraping off the adhesive film with a spatula (scraper) or the like, and adhering with a solvent. It is carried out by a method of melting and wiping off the film, a method of swelling the adhesive film with a solvent and peeling it off.
しかしながら、ヘラ等で接着フィルムを掻き取る方法
は、フィルムを剥離すること自体困難で、時間及び労力
を非常に要する。又、奇麗にフィルムを剥離できず、接
着剤の跡が被着体に残るため、フィルムを剥離した後、
接着剤を溶剤で拭き取る必要がある。更に、被着体（下
地）を損傷する可能性が高い。However, in the method of scraping off the adhesive film with a spatula or the like, it is difficult to peel the film itself, and it takes a lot of time and labor. Also, since the film cannot be peeled off neatly and traces of the adhesive remain on the adherend, after peeling off the film,
It is necessary to wipe off the adhesive with a solvent. Further, there is a high possibility that the adherend (base) will be damaged.
また、溶剤で接着フィルムを溶かして拭い去る方法
は、短時間でフィルムや接着剤を溶解する適当な溶剤が
なく、時間や労力を要する。又、周囲を汚さずに溶けた
接着剤を拭き取ることが困難であり、被着体が溶剤で冒
されることがある。更に、溶剤蒸気が揮散充満し易く、
臭気がひどい上、危険性も大きい。In addition, the method of dissolving the adhesive film with a solvent and wiping it off requires time and labor because there is no suitable solvent for dissolving the film and the adhesive in a short time. Further, it is difficult to wipe off the melted adhesive without polluting the surroundings, and the adherend may be affected by the solvent. Furthermore, the solvent vapor is easy to volatilize and fill,
It has a bad odor and a great danger.
また、溶剤で接着フィルムを膨潤させて剥ぎ取る方法
は、フィルムが細かく破けるため、剥離作業が非能率的
である。又、被着体の全面に接着剤が残り、後に溶剤等
で拭い取る必要がある。Further, the method of swelling the adhesive film with a solvent and peeling it off is inefficient because the film is finely broken. Further, the adhesive remains on the entire surface of the adherend, and it is necessary to wipe it off later with a solvent or the like.
また、後二者の溶剤を用いる方法においては、フィル
ムと接着剤とを別々に除去する必要があり、フィルム用
の溶剤と接着剤用の溶剤とを区別して使用する必要があ
るため、剥離作業が煩わしい。Further, in the latter two methods using a solvent, it is necessary to remove the film and the adhesive separately, it is necessary to distinguish between the solvent for the film and the solvent for the adhesive, so the peeling work Is annoying.
従って、本発明の目的は、フィルム剥離の際の作業性
を向上でき、フィルムの剥離が容易で、接着剤が被着体
に残らず、被着体を傷めず、拭き取り等の後処理を要せ

提供することにある。Therefore, the object of the present invention is to improve the workability at the time of peeling the film, the film can be easily peeled, the adhesive does not remain on the adherend, the adherend is not damaged, and post-treatment such as wiping is required. It is an object of the present invention to provide a novel film peeling agent which has various effects such as being capable of uniformly peeling even a film which is deteriorated and has cracks due to no deterioration.
本発明者らは、上記の目的を達成すべく鋭意検討した

剥離できることを知見した。As a result of intensive studies to achieve the above objects, the present inventors applied a film with a composition containing a specific amount of an organic acid in a resin solution obtained by dissolving a specific amount of a specific resin in a specific solvent, or When the film is peeled off after spraying, the workability at the time of peeling the film can be improved, the film can be easily peeled off, the adhesive does not remain on the adherend, the post-treatment such as wiping is not required, and the film deteriorates. It was found that even a cracked film can be peeled off uniformly.

The above object is achieved by providing a characteristic film release agent.
以下、本発明のフィルム剥離剤について詳述する。 Hereinafter, the film release agent of the present invention will be described in detail.

流動性が劣り、塗布し難い。The thermoplastic resin, which is one component of the film release agent of the present invention, forms a film when the film release agent of the present invention is applied to or sprayed on the film to reinforce the film, It holds a solvent that is another constituent and suppresses its evaporation and outflow. It has a solubility parameter (SP value) of 8 to 11 and contains 60% or more of vinyl chloride, and has a number average degree of polymerization () of 200 to A thermoplastic resin of 2000, preferably having a solubility parameter (SP value) of 8
A thermoplastic resin of ˜11 and vinyl chloride / vinyl acetate = 60 to 100/40 to 0, which is a homo- or copolymer, and is 200 to 2000 is used. If the SP value is less than 8 or more than 11, the solubility in the solvent used is poor and the adhesion to the film is poor. Is less than 200, the coating film after drying is too brittle and difficult to reinforce the film, on the other hand, when it is 2000 or more, the solubility in the solvent is poor, the viscosity of the film release agent is high, and the fluidity is poor, Difficult to apply.

る。The solvent, which is another constituent of the film release agent of the present invention, swells and softens the film when the film release agent of the present invention is applied to or sprayed on the film, and
It reduces the adhesive strength of the adhesive and makes it easier to peel the film from the adherend. The SP value is 8-11 and the boiling point is 40.
A solvent having a temperature of up to 250 ° C. and capable of dissolving the thermoplastic resin is used. When the SP value is less than 8 or more than 11, it is difficult to dissolve the thermoplastic resin and the film cannot be swollen and softened. When the boiling point is less than 40 ° C, the volatilization rate is fast and a sufficient amount of solvent cannot reach the adhesive layer, resulting in 250 ° C.
If it is more than that, the volatilization rate is too slow, and it takes too long to form a coating having sufficient strength for peeling the film.

脂溶液100重量部に対し、上記有機酸0.5〜10重量部を含
有させてなるものである。Thus, the film release agent of the present invention contains 0.5 to 10 parts by weight of the above organic acid to 100 parts by weight of a resin solution consisting of 5 to 80% by weight of the thermoplastic resin and 95 to 20% by weight of the solvent. It is contained.

溶解性が悪い上、フィルム剥離剤の安定性が悪くなり、
有機酸を過剰に配合しただけの効果が認められない。If the amount of the thermoplastic resin is less than 5% by weight or the amount of the solvent is 95% by weight, the coating film formed after coating or spraying the film release agent of the present invention on the film and drying the film is too thin. Cannot be reinforced, and it is not possible to hold the above solvent enough to penetrate the adhesive layer of the film. On the other hand, if the thermoplastic resin is more than 80% by weight or the solvent is more than 20% by weight, it is difficult to dissolve in the solvent and the viscosity becomes too high, resulting in lack of fluidity. Is difficult to apply. Further, if the organic acid is less than 0.5 parts by weight, there is no compounding effect of the organic acid,
When the film release agent is applied or sprayed on the film, the tackiness of the adhesive cannot be weakened and the adhesive strength cannot be reduced. On the contrary, when the organic acid is more than 10 parts by weight, the solubility of the film is poor and the stability of the film release agent is poor,
The effect of simply blending the organic acid in excess is not recognized.

性が極度に悪くなり易い。Further, in the film release agent of the present invention, in order to improve the film release agent and reduce the force required for release, it is preferable to add 0.5 to 5 parts by weight of a surfactant to 100 parts by weight of the thermoplastic resin. it can. Preferred surfactants to be contained include, for example, sodium alkylbenzene sulfonate, fatty acid salt, alkyl sulfate, alkylamine acetate, polyoxyethylene alkyl ether, sorbitan ester. When the amount of the surfactant is less than 0.5 part by weight, the adhesive strength of the adhesive of the film is hard to be lowered, and the adhesive may remain on the adherend when the film is peeled off. On the other hand, when it is more than 5 parts by weight, stickiness increases and the peeling workability of the film is apt to become extremely poor.

It may contain 0 parts by weight. Examples of the solvent having a preferable polar group to be contained include isopropyl alcohol, ethanol, methanol, ethylene glycol, glycerin, diethylene glycol and the like. or,
When the amount of the solvent having a polar group is less than 1 part by weight, it is difficult to uniformly disperse the surfactant in the film peeling agent and easily separate, so that it is difficult to obtain the effect by blending the surfactant. On the other hand, when the amount is more than 40 parts by weight, the solubility of the resin of the thermoplastic resin is likely to be lowered, and the film release agent tends to be cloudy or the thermoplastic resin is likely to be reprecipitated, so that the stability of the film release agent is difficult to obtain.

理を要せず、且つ劣化して亀裂の入ったフィルムでも均
一に剥離できる。The amount of the film peeling agent used for peeling the film as described above is preferably about 50 to 250 g / area of the film (m 2 ). Since such an amount used is much smaller than the amount used in the conventional method of peeling an adhesive film by using a solvent, the problem as in the conventional method does not occur. Further, when the film is peeled off by coating or spraying the film peeling agent of the present invention, the workability at the time of peeling the film can be improved, the peeling of the film is easy, and the adhesive does not remain on the adherend, The adherend is not damaged, no post-treatment such as wiping is required, and even a deteriorated and cracked film can be peeled off uniformly.

ある。The peeling of the film can be carried out by hand as described above, or, for example, after coating or spraying the film peeling agent of the present invention on the adhesive film, water or warm water can be sprayed on the film at high pressure. Water or warm water is preferably sprayed at a regular discharge pressure (internal pressure of the nozzle during spraying work) of 30 Kg / cm 2 or more, and spraying warm water can peel the film in a shorter time. Regular discharge pressure of hot water
If it is less than 30 kg / cm 2 , the hot water discharge pressure from the nozzle is low, and it is difficult to peel off the film. For this spraying, it is preferable to use a nozzle having high straightness of sprayed water or hot water. Further, this spraying is preferably performed toward the peripheral portion (edge portion) of the film, and usually,
1 to 100 cm at an angle of 10 to 70 degrees, preferably 20 to 45 degrees toward the periphery of the adhesive film, particularly the adhesive layer (adhesive layer)
It is preferable to carry out from a certain distance. The discharge rate of water or warm water is not particularly limited, but is usually 1 to 100 / min, preferably 5 to 30 / min, more preferably 10 to 20 / min.
