液（分散液）のいずれであってもよい。The glue used in this invention may be the same as that used in conventional glue glue, but in this invention,
What is usually called gelatin will be included in glue. The glue is extracted from raw materials such as animal skins, bones, muscles and tendons at a high temperature of about 80 ° C. or higher and contains a large amount of impurities. On the other hand, gelatin is extracted at a temperature of about 50 to 80 ° C. from a material having a quality higher than that of glue, has a higher transparency, has a higher jelly strength, and has an extremely small amount of impurities. As the glue or glue solution, a conventional compound glue, that is, glue in which at least one kind of a plasticizer, an antifoaming agent, an antiseptic and other substances are mixed may be used. The compound glue may be a powder or a solution (dispersion liquid).

At least one such as defoamers, preservatives and other substances
Seeds are blended as needed. Plasticizers are usually preferred because they improve adhesion and / or flexibility to the processed paper. As the plasticizer, there are those which have been conventionally used for glue-based adhesives (for example, glycerin, ethylene glycol, sugar sugar), but especially, the toluenesulfonamide plasticizer which is essential in the spill invention is It is very effective because it exerts the effect of improving the adhesiveness to the processed paper without causing a decrease in the adhesive force. Examples of the toluenesulfonamide plasticizer include N-ethyl-o.
-Toluenesulfonamide, N-ethyl-p-toluenesulfonamide and the like. The toluenesulfonamide-based plasticizer may be used alone without being used in combination with the plasticizer conventionally used for glue glue. As the defoaming agent and the preservative, those used in the conventional glue-based adhesive are used.
この発明にかかるニカワ系接着剤のニカワの濃度は、特
に限定はないが、重量濃度で５〜８０％が好ましい。こ
の濃度範囲を上回ると、ニカワ系接着剤の溶液粘度が高
くなって塗工適正が悪くなるおそれがあり、この濃度範
囲を下回ると、ゼリー強度が低くなって初期接着性が低
下するおそれがある。The glue concentration of the glue-based adhesive according to the present invention is not particularly limited, but is preferably 5 to 80% by weight. If it exceeds this concentration range, the solution viscosity of the glue-based adhesive may become high and coating suitability may deteriorate, and if it falls below this concentration range, the jelly strength may become low and the initial adhesiveness may decrease. .

剤のゼリー強度が大幅に低下し、初期接着力が大きく低
減する。また、エマルジョン固形分の割合が前記範囲を
下回ると、加工紙に対する接着性があまり向上しないお
それがある。In the glue-based adhesive according to the present invention, the blending ratio of the acrylic polymer emulsion is such that the glue solid content is 10
The solid content of the acrylic polymer emulsion is 55 parts by weight or less with respect to 0 parts by weight, but it is 10 parts by weight or more, preferably 20 parts by weight or more.
When the emulsion solid content exceeds 55 parts by weight, the jelly strength of the glue-based adhesive is significantly reduced and the initial adhesive strength is significantly reduced. Further, when the ratio of the emulsion solid content is less than the above range, the adhesiveness to the processed paper may not be improved so much.

ことがある。When the plasticizer is added, the plasticizer is preferably added in an amount of 30% or less, and more preferably 20% or less, based on the total weight of the glue-based adhesive. When the plasticizer content exceeds the above range, physical properties such as initial adhesiveness of the glue-based adhesive may deteriorate. When the defoaming agent is added, it is preferable to add the defoaming agent in an amount of 0.1 to 1.0% based on the total weight of the glue-based adhesive. If it is less than this range, the effect of the defoaming agent may not appear, and if it exceeds this range, poor coating and poor adhesion of the glue-based adhesive may occur. When adding an antiseptic agent, the antiseptic agent 0.
It is preferable to add it so as to be 1 to 2.0%. Below this range, the effect of the preservative may not be exhibited, and above this range, the physical properties of the glue-based adhesive may deteriorate.

It has good adhesiveness to processed paper as well as having the property of rapid expression. Therefore, the glue-based adhesive of the present invention is used for adhesion between processed papers, adhesion between processed papers and other papers capable of absorbing water or evaporating water, binding for book binding, back sticking, etc. It can be used preferably. Further, it can also be used for bonding other than processed paper, which has not been able to use glue-based adhesives in the past. Of course, the glue-based adhesive of the present invention has good adhesiveness to paper other than processed paper, wood, cloth and the like.

７の初期接着力データの比較から分かる。The amount of acrylic polymer emulsion is 55
If the amount is less than or equal to parts by weight, the decrease in initial adhesive strength is extremely small.
It can be seen from the initial adhesive strength data of Reference Examples 1 to 6 and Comparative Examples 1 and 2 in Table 1. Further, the fact that the compounding of the toluenesulfonamide-based plasticizer does not actually cause a decrease in the initial adhesive strength is because the initial adhesive strength data of Example 1 and Reference Example 1 in Table 1 or Example 2 and Reference Example 7 You can see from the comparison.

囲に留められる。On the other hand, it can be seen from the comparison of the initial adhesive force data of Comparative Example 1 and Reference Example 3 that the initial adhesive force is significantly reduced when the amount of the acrylic polymer emulsion is extremely large (exceeding 55 parts by weight). . When the blending amount of the acrylic polymer emulsion is increased, when glycerin for improving flexibility is added, the initial adhesive force decreases until it becomes impractical as shown in the initial adhesive force data of Reference Example 8. However, in the case of Example 2, since the blending amount of the acrylic polymer resin emulsion is suppressed to 55 parts by weight or less, even if glycerin is added, the initial adhesive strength is still within the range of practicality.

It is highly practical because it has strong adhesion to paper.
