【発明の詳細な説明】
［産業上の利用分野］
本発明は、果実の保護等に用いられる果実紙用の接着剤
に関するものであり、特に、例えばパラフィンやシリコ
ーン樹脂を含浸等により加工した特殊加工紙用の接着剤
に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to adhesives for fruit paper used to protect fruits, etc., and particularly to special adhesives processed by impregnation with paraffin or silicone resin, etc. It relates to adhesives for processed paper.
［従来の技術と発明が解決しようとする課題］果実紙は
一般に袋状にして使用され、この袋は果実の生育の初期
に果実に被せられて、果実、例えば、なし、りんご、ぶ
どう等を病害虫から保護すると同時に、紫外線を適度に
透過させて果実の順調な生育を促進するのに用いられる
。[Prior Art and Problems to be Solved by the Invention] Fruit paper is generally used in the form of a bag, and this bag is placed over the fruit at the early stage of fruit growth to cover the fruit, such as pears, apples, grapes, etc. It is used to protect against pests and diseases, and at the same time to promote the smooth growth of fruits by transmitting a moderate amount of ultraviolet rays.
果実袋を作る際には、果実紙を袋状にし、袋の開口部以
外の周縁部を接着剤で貼合せる。その際、上記のような
撥水性の特殊加工された紙は、水系樹脂の接着剤では均
一塗布が困難なため、従来では溶剤系樹脂の接着剤を使
用せざるを得なかった。When making a fruit bag, fruit paper is shaped into a bag, and the periphery of the bag other than the opening is pasted with adhesive. In this case, since it is difficult to uniformly apply a water-based resin adhesive to the above-mentioned specially treated water-repellent paper, conventionally, a solvent-based resin adhesive had to be used.
しかし、溶剤系樹脂の接着剤を用いると次のような欠点
がある。すなわち、（１）溶剤によって、せっかく特殊
加工した含浸成分が溶解するため、紫外線等の透過に悪
影響が出て、果実の生育に良くない、（２）溶剤による
安全、衛生、毒性上の問題がある、（３）接着力が強す
ぎて果実が接着剤で汚染される、（４）コストが高くな
る。However, the use of solvent-based resin adhesives has the following drawbacks. In other words, (1) solvents dissolve specially processed impregnated ingredients, which has a negative effect on the transmission of ultraviolet rays, which is bad for fruit growth; (2) solvents pose safety, hygiene, and toxicity problems. (3) The adhesive force is too strong and the fruit is contaminated with the adhesive; (4) The cost is high.

接着剤は貼合峙に加熱処理を必要とし、常温接着はでき
ない。In addition, as a conventionally known water-based emulsion type adhesive for water-repellent paper, for example, there is Japanese Patent Application Laid-Open No. 53-91940, but this is an emulsion whose main component is an ethylene-vinyl acetate copolymer, and this emulsion alone cannot be used. The wax paper that is the object of the invention cannot be laminated at all. Furthermore, a water-repellent cardboard adhesive containing a vinyl acetate emulsion and an acrylic-styrene copolymer latex as essential components is disclosed in JP-A-58-98239, but this adhesive is heat-treated before lamination. , and cannot be bonded at room temperature.
［発明の構或］
本発明者は、上記の溶剤型接着剤の欠点を改善し、几つ
公知の水性エマルジョン型接着剤より優れた接着特性、
作業性を有する果実紙用接着剤を開発すべく鋭意検討し
た結果、以下の接着剤が優れていることを見いだした。[Structure of the Invention] The present inventors have solved the drawbacks of the above-mentioned solvent-based adhesives, and created adhesive properties superior to those of known water-based emulsion-based adhesives.
As a result of intensive study to develop an adhesive for fruit paper that has workability, we discovered that the following adhesive is excellent.
すなわち、本発明の接着剤は、天然ゴムラテックスとス
チレン系共重合体ラテックスとの混合物に、アルカリ可
溶性樹脂と、ロジンと、有機溶剤と、可塑剤とを配合し
たことを特徴とする果実紙用接着剤である。That is, the adhesive of the present invention is for fruit paper, which is characterized by blending an alkali-soluble resin, rosin, an organic solvent, and a plasticizer into a mixture of natural rubber latex and styrene copolymer latex. It is an adhesive.
より具体的には、上記の天然ゴムラテックスが１０〜３
０重量部、スチレン系共重合体ラテックスが１０〜３０
重量部、アルカリ可溶性樹脂が０，３〜１重量部、ロジ
ンが１０〜３０重量部、有機溶剤が１０〜３０重量部、
可塑剤が３〜１０重量部であるものが好ましい。More specifically, the above natural rubber latex is 10 to 3
0 parts by weight, 10 to 30 parts of styrene copolymer latex
Parts by weight, 0.3 to 1 part by weight of alkali-soluble resin, 10 to 30 parts by weight of rosin, 10 to 30 parts by weight of organic solvent,
Preferably, the amount of plasticizer is 3 to 10 parts by weight.
本発明の接着剤に用いられる天然ゴムラテックスは、粘
着性および接着性を付与するために必要である。その量
は１０〜３０重量部であり、この範囲を外れると粘着性
および接着性が低下する。The natural rubber latex used in the adhesive of the present invention is necessary to impart tack and adhesive properties. The amount is 10 to 30 parts by weight; outside this range, the tackiness and adhesion will decrease.
スチレン系共重合体ラテックスは天然ゴムラテックスの
老化を防止し、接着性を向上させるために必要である。Styrenic copolymer latex is necessary to prevent aging of natural rubber latex and improve adhesion.
この共重合ラテックスとしては、スチレンーブタジエン
共重合体、スチレンーネオブレン共重合体等が挙げられ
る。その使用量は１０〜３０重量部であり、この範囲を
外れると接着性か低下するので好ましくない。Examples of this copolymer latex include styrene-butadiene copolymer, styrene-neobrene copolymer, and the like. The amount used is 10 to 30 parts by weight, and if it deviates from this range, the adhesiveness will deteriorate, which is not preferable.
アルカリ可溶性樹脂としては、例えば、カゼイン等を使
用でき、その使用量は０．３〜１重量部である
ロジンは粘着付与剤として必要であり、例えばピコライ
トＡ−１１５（商品名）などが挙げられる。その使用量

与剤としての性能が低下する。As the alkali-soluble resin, for example, casein can be used, and the amount used is 0.3 to 1 part by weight.Rosin is necessary as a tackifier, and examples include Picolite A-115 (trade name). . The amount used is 10 to 30 parts by weight, and if it is out of this range, the performance as a tackifier will deteriorate.

げることができる。樹脂との相溶性、作業性等の観点か
ら特に芳香族系溶剤が好ましい。有機溶剤の使用量は１
０〜３０重量部で、この範囲を外れると樹脂との溶解性
、作業性が低下する。Examples of the H organic solvent include aromatic solvents such as toluene and xylene, such as n-hexane, n-bentane, and n-
Examples include aliphatic solvents such as heptane, ketone solvents such as methyl ethyl ketone and methyl isobutyl ketone, and ester solvents such as ethyl acetate and butyl acetate. Aromatic solvents are particularly preferred from the viewpoint of compatibility with the resin, workability, and the like. The amount of organic solvent used is 1
The amount is 0 to 30 parts by weight, and if it is outside this range, the solubility with the resin and workability will decrease.
可塑剤は樹脂の可塑化に必要であり、かつ接着性も向上
する。可塑剤としては、例えばフタル酸ジエチル、フタ
ル酸ジブチル、フチル酸ジオクチル、フタル酸ブチルベ

、この範囲を外れると接着剤の可塑化が不十分となった
り、可塑剤の移行によって接着性が低下する。Plasticizers are necessary to plasticize the resin and also improve adhesive properties. Examples of plasticizers include phthalate esters such as diethyl phthalate, dibutyl phthalate, dioctyl phthalate, butylbenzine phthalate, glycerin,
Examples include polyhydric alcohol plasticizers such as diethylene glycol. The amount used is 3 to 10 parts by weight, and if it is out of this range, the plasticization of the adhesive may be insufficient or the adhesiveness may deteriorate due to migration of the plasticizer.

クス紙が破れた。The coating amount was 30 to 40 μm (dry). Immediately after coating, it was overlapped with the back side of wax paper and pressed with a rubber roller. After drying this by leaving it for 24 hours at 20°C x 65% RH, a peel test was conducted. As a result, the wax paper bonded with the above adhesive was not peeled off by the adhesive layer and the wax paper was torn.
また、ワックス紙の樹脂分の溶解は認められず、果実へ
の悪影響は全く認められなかった。Further, no dissolution of the resin content of the wax paper was observed, and no adverse effects on the fruit were observed at all.

), the adhesive strength is strong enough to tear the wax paper as in the present invention, but the resin content on the surface of the wax paper dissolves, and the light transmittance of this dissolved area decreases. The size of the fruit became large and bleed appeared on the surface of the fruit. Furthermore, when using a solvent-based adhesive, the resin content of the wax paper seeped into the wax paper bag along with the solvent and came into contact with the fruit surface, inhibiting fruit growth in that area.
