用後の取扱いが煩雑であった。2. Description of the Related Art Conventionally, paper, non-woven fabric, cloth or a laminated body thereof has been used as an oil absorbing sheet. These are widely used for treating surplus oil of oily foods, waste oil treatment, treatment of leaked oil from various machines, treatment of various solvents, and the like. However, these oil-absorbent sheets have a mechanism of retaining oil in the voids by utilizing the capillary phenomenon of the sheet,
There are problems that the unit oil absorption per oil-absorbent sheet is small and that oil leaks when pressed. Therefore, the amount of the oil-absorbent sheet used is inevitably large, and handling at the time of use or after use is complicated.

る。The highly oil-absorbent resin is preferably dispersed in an aqueous adhesive in the form of fine particles. That is, as shown in FIGS. 1 to 3, the oil-absorbent sheet of the present invention is composed of an oil-permeable packaging material 1, a highly oil-absorbent resin-containing adhesive layer 2, and an optional packaging material 3. Here, the highly oil-absorbent resin-containing adhesive layer 2 is formed by applying a water-based adhesive containing the acrylic highly oil-absorbent resin 5 to the reticulated packaging material 4 by an appropriate means such as dipping, coating or spraying. is there.

As the reticulated wrapping material, a split nonwoven fabric made of polyvinyl alcohol fiber can be preferably used, and the basis weight is preferably 10 g / m 2 or more and 50 g / m 2 or less. When the basis weight is less than 10 g / m 2 , the amount of the highly oil-absorbent resin-containing adhesive held by the reticulated packaging material is small, and the adhesive strength and oil absorption amount are insufficient, which is not preferable. Further, even if the basis weight exceeds 50 g / m 2 , the highly oil-absorbent resin-containing adhesive held by the reticulated packaging material does not increase, resulting in high cost.

なる。As the water-based adhesives, natural water-based adhesives such as starch paste, dextrin, glue and gum arabic, and synthetic water-based adhesives such as polyvinyl alcohol and vinyl acetate emulsion can be used. It is not preferable to use an oil-based adhesive when dispersing the highly oil-absorbent resin, because absorption of the solvent by the highly oil-absorbent resin occurs. The content of the highly oil-absorbent resin in the water-based adhesive depends on the kind of the water-based adhesive, but is preferably 1 to 50% by weight. If the content is less than 1% by weight, the oil absorbency becomes insufficient, and if it exceeds 50% by weight, the adhesive force between the packaging materials decreases. The amount of the water-based adhesive containing a highly oil-absorbent resin applied to the packaging material is preferably 5 to 100 g / m 2 in terms of solid matter. When the coating amount is less than 5 g / m 2 , the oil absorbency is insufficient, and when the coating amount exceeds 100 g / m 2 , the oil absorbency does not increase and the cost increases.
