【産業上の利用分野】本発明は、接着層が厚かったり、
ばらついている場合の接着に有効な水分散型接着剤組成
物に関する。BACKGROUND OF THE INVENTION The present invention relates to a thick adhesive layer,
The present invention relates to a water-dispersible adhesive composition that is effective for adhesion when there are variations.
【０００２】[0002]

た後に貼り合わせていた。2. Description of the Related Art When non-porous materials such as metal and plastics are bonded together using a water-dispersible adhesive, water in the adhesive cannot be volatilized after bonding. It was previously dried to form an adhesive layer from which water was removed, and then adhered.

【発明が解決しようとする課題】従って、非孔質体に塗
布した接着層が厚い場合には、表面が乾燥皮膜化して内
部に水分が残存する状態で貼り合わせるために接着層の
凝集力の低下による接着力不足が生じ易かった。Therefore, when the adhesive layer applied to the non-porous body is thick, the cohesive force of the adhesive layer is increased in order to attach the adhesive layer in a state where the surface becomes a dry film and moisture remains inside. The adhesive strength was likely to be insufficient due to deterioration.
【０００４】また、反対に非孔質体に塗布した接着層が
薄い場合には、接着層中の水分が十分に揮発した状態で
貼り合わせるために接着層自体の凝集力は強いものの、
接着層が薄いために塗布面同士の接触面積、すなわち有
効接着面積が少なくなり、接着力不足を生じた。On the other hand, when the adhesive layer applied to the non-porous body is thin, the adhesive layer itself has a strong cohesive force because the adhesive layer is attached in a state where the water content in the adhesive layer is sufficiently volatilized.
Since the adhesive layer was thin, the contact area between the coated surfaces, that is, the effective adhesive area was reduced, resulting in insufficient adhesive strength.
【０００５】これらの現象は、被着体と被着体の間隔、
すなわち接着層の厚さが大きかったり、ばらついている
場合に生じ易かった。従って、水分散型接着剤による非
孔質体の接着はさまざまな制約を受けた。These phenomena are caused by the distance between adherends,
That is, it was likely to occur when the thickness of the adhesive layer was large or varied. Therefore, the adhesion of the non-porous material with the water-dispersed adhesive is subject to various restrictions.
【０００６】本発明の目的は、非孔質体同士の接着に際

を提供することにある。An object of the present invention is to provide a water-dispersible adhesive composition which does not cause insufficient adhesive force due to residual moisture or insufficient effective adhesive area as described above when adhering non-porous materials. .

As the rubber-like elastic powder having an average particle diameter of 1.5 and an average particle diameter of 0.1 to 0.5 mm, shore such as natural rubber, butyl rubber, isoprene rubber, urethane rubber, silicone rubber, and acrylic rubber can be used. It is produced by crushing and sizing a rubber elastic material having an A hardness of 30 to 80. If the true specific gravity is 0.5 or less, the particles may float on the surface, and if the true specific gravity is 1.5 or less, they may settle. The average particle size is 0.
If it is less than 1 mm, it will be almost the same as the dry film thickness of water-dispersed resin,
If the effect of the present invention is not recognized and the thickness is 0.5 mm or more, the thickness of the adhesive layer becomes too large, or the volume ratio of the rubber-like elastic powder becomes too large, resulting in a decrease in adhesive strength.

Although it is determined by the physical properties such as specific gravity and average particle size of each, the amount of the rubber-like elastic powder is added and mixed with 100 parts of the water-dispersible resin in terms of the solid content weight. . If the amount is 10 parts or less, the effect of the present invention is not recognized, and
When the amount is more than the above range, the adhesion to the adherend deteriorates and the adhesive strength is reduced. In the water-dispersed adhesive composition according to the present invention, if desired, known modifiers such as a coloring pigment, a filler, a thickener, a defoaming agent and an antiseptic can be used in combination.
