リ溶解度が劣る問題がある。Traditionally, hot-melt adhesives have been the mainstream adhesive for perfect binding, but problems such as maintenance difficulties with melting equipment, demands for energy conservation,
Hygiene problems, problems with alkali solubility during waste paper recovery, etc. Among water-based adhesives, vinyl acetate polymer emulsion alone is thermoplastic and therefore has insufficient initial drying properties, resulting in poor initial adhesion and the ItI cold of the film. Sexuality also decreases. Furthermore, acrylic polymer emulsions have problems such as odor and poor alkali solubility during waste paper recovery. Even ethylene-vinyl acetate polymer emulsions have a problem of poor alkali solubility during waste paper recovery.
本発明者らは前述の問題点を改良すべく鋭意研究の結果

ことを特徴とする無線綴用接着剤。That is, the vinyl acetate polymer emulsion contains 3 to 20 parts by weight of a plasticizer, 10 to 60 parts by weight of raw starch, 01 to 2 parts by weight of a dispersant, and 02 to 05 parts by weight of a preservative. An adhesive for perfect binding.
可塑剤は酢酸ビニル重合体を可塑化し、皮膜を柔軟化す

ルトリブチル、クエン酸アセチルトリメチル、クエン酸
アセチル） ｌ）エチルなどグリセリン系例えばトリア
セチンなどが挙げられる。Plasticizers plasticize the vinyl acetate polymer and soften the film, so they do not particularly play a role in improving cold resistance. The timing and proportion of plasticizer use is not specified, but it is carried out separately during emulsion polymerization of vinyl acetate and after the completion of emulsion polymerization, and the proportion of plasticizer used is at least 50% by weight of the total amount of plasticizer during emulsion polymerization. It is preferable. The type and t7 are fucuric acid esters, such as DBP, DOP, BBP, D
Examples include citric acid esters such as BXP, such as acetyltributyl citrate, acetyltrimethyl citrate, acetyl citrate); and glycerols such as ethyl, such as triacetin.
生派粉は熱接着性を酢酸ビニル重合体エマルジョンに伺

及ぼすものである。種類としては加熱溶解するタイプで
、例えばトウモロコシ澱粉、小麦粉澱粉、ジャガイモ澱
粉、ザツマイモ澱粉などを挙げることができる。The raw powder imparts thermal adhesion to the vinyl acetate polymer emulsion, and influences initial adhesion, adhesion, and ml cold resistance. Types include those that can be dissolved by heating, such as corn starch, wheat starch, potato starch, and sweet potato starch.

間安定に保持するもので、例えばトリボ１４１ソーダ、
β−ナフクレンスルホン酸ホルマリン縮合物（花王石鹸
社製デモールＮ）などが挙げられる。The dispersant is one that keeps the vinyl acetate polymer emulsion and raw starch stable for a long period of time, such as Tribo 141 soda,
Examples include β-nafucrenesulfonic acid formalin condensate (Demol N manufactured by Kao Soap Co., Ltd.).
必要があり、例えばホルマリン、スラオフ（成田薬品工

らの使用量は酢酸ビニル重合体エマルジョン１００重量
部に灼し可塑剤が３〜２０重量部の範囲であり、３重量
部未満では皮膜の耐寒性が低下し、ひびわれ等が発生す
る。For example, formalin, Suraf (manufactured by Narita Pharmaceutical Co., Ltd.), Slamony B (manufactured by Narita Pharmaceutical Co., Ltd.), Dowsil 100, Dowsil 200 (manufactured by Dow Chemical Co., Ltd.). The amount of these used is in the range of 3 to 20 parts by weight of the plasticizer per 100 parts by weight of the vinyl acetate polymer emulsion, and if it is less than 3 parts by weight, the cold resistance of the film will decrease and cracks will occur.
一方、２０重置部を越えると初期接着性が低下するので
好ましくない。On the other hand, if the number of overlapping parts exceeds 20, the initial adhesiveness decreases, which is not preferable.
生澱粉は酢酸ビニル重合体エマルジョン１００重量部に
対し１０〜６０重量部の範囲であり、１０重量部未満で
は初期接着性が低下し、６０重量部を越えると耐寒性及
び接着性カー低下するので好ましくない。The amount of raw starch is in the range of 10 to 60 parts by weight per 100 parts by weight of the vinyl acetate polymer emulsion; if it is less than 10 parts by weight, the initial adhesion will decrease, and if it exceeds 60 parts by weight, the cold resistance and adhesive properties will decrease. Undesirable.
分散剤は酢酸ビニル重合体エマルジョン１００Ｍ畦部に
対し０１〜２重量部の範囲であり、０１重量部未満では
生澱粉がママコになり、初期接着性が低下し、２重量部
を越えると粘度低下が著しく、塗工性に悪影響を及ぼす
ので好ましくない。The amount of the dispersant is in the range of 01 to 2 parts by weight per 100M ridge of the vinyl acetate polymer emulsion.If it is less than 01 parts by weight, the raw starch will become lumpy and the initial adhesion will decrease, and if it exceeds 2 parts by weight, the viscosity will decrease. This is not preferable because it has a significant negative effect on coating properties.

It is 02 to 05 parts by weight, and if it is less than 02 parts by weight, the raw starch is likely to rot, and if it exceeds 05 parts by weight, it may discolor or separate, which is undesirable due to hygiene problems.
