の損失があつた。 However, when using this kraft paper,
The resin tends to impregnate the kraft paper, and the foamed urethane foam and the kraft paper strongly adhere to each other, making it impossible to remove the kraft paper from the urethane foam smoothly. If you try to do so, the surface of the urethane foam will peel off and pieces of urethane foam will stick to the kraft paper, which not only makes it impossible to reuse the kraft paper, but also causes material damage to the urethane foam product and causes the urethane foam surface to become uneven. There were losses.

利用できる等のメリツトがあるものである。 To briefly explain the process paper according to this prior art, it is a process paper for manufacturing urethane foam, which is made by extrusion laminating a molten film layer of polyethylene or the like on kraft paper in a temporarily attached state. The laminate film layer is arranged so that it can be unwound and rolled up using a predetermined method so that the laminate film layer side faces the bottom, top, and right and left side wall portions of the space where the urethane foam is formed. The urethane foam is obtained by completely adhering it to the surface of the urethane foam in a thin film, and then smoothly peeling off only the kraft paper and winding it up.The yield rate of the urethane foam product relative to the urethane resin raw material is Not only does it have good properties, but it also has the advantage that the kraft paper that has been peeled off and rolled up can be reused.

あつた。(Problems to be Solved by the Invention) However, if the process paper for manufacturing urethane foam according to the above-mentioned prior art is used for manufacturing urethane foam, there are few pinholes in the laminate film layer portion, resulting in a lack of air permeability. As a result, the foaming gas generated during foaming of the urethane resin is not sufficiently degassed, which often causes uneven foaming at the interface between the urethane foam and the laminate film surface of the process paper. In addition, as a means of obtaining this process paper, it is difficult to control the working conditions for laminating the extruded laminated film layer on the kraft paper in a temporarily attached state.
There was also a problem in that the peeling force of the laminate film to the kraft paper in the obtained process paper varied.

しては0.5〜3.0Kg／cmが望ましい。 Here, the term "breathable base paper" means, for example, paper with breathability such as kraft paper, and the term "plastic film" refers to a film formed mainly from polyolefins such as polyethylene or polypropylene by the inflation and T-die methods. Preferably, one or both sides of this plastic film have been subjected to corona discharge treatment for the purpose of improving wettability and adhesion with urethane resin when used as process paper. The air-permeable base paper and the plastic film are in a temporarily attached state because the adhesive strength between the base paper and the plastic film layer is the same as the urethane foam generated by foaming the polyurethane resin and the plastic film layer. This means that the adhesive strength can be lower than the adhesive strength of . As a means for temporarily attaching the breathable base paper and the plastic film and as a means for making micropores, a large number of acicular protrusions (for example,
A plastic film is supplied from one side and a breathable base paper is simultaneously supplied from the other between a rubber roll and a heat roll on which needle-like parts with a thickness of 0.1 mm and a diameter of 0.5 mm are protruded at a predetermined density. The most suitable means is to temporarily attach the air permeable base paper and the plastic film by crimping and integrating the two, and at the same time to make micropores by piercing the needle-like protrusions in the plastic film layer side. be. At this time, in order to prevent the breathable base paper and the plastic film from completely adhering, the working conditions for the hot roll are preferably a heating condition of 150 to 200°C and a pressure condition of 0.5 to 3.0 kg/cm. .

も容易である。 The above-mentioned micropores are exemplified as penetrating both the plastic film and the breathable base paper, but for the purpose of degassing the foaming gas generated during molding of the urethane foam, it is recommended that the micropores be perforated at least in the plastic film layer. It is sufficient if it is set up. Also,
The thickness of the needle-like protrusions protruding from the circumferential surface of the heat roll and the number of needle-like protrusions per unit area (density of the protrusions) determine the air permeability of the process paper itself and the ventilation with the plastic film. The state of temporary adhesion of the adhesive base paper can be easily controlled.Furthermore, plastic films are mainly formed by inflation molding or T-die methods, and the addition of slip agents, tackifiers, etc. to the film can be easily controlled. Since the operation is simple, it is also easy to adjust the adhesive strength of the plastic film layer of the processing paper to the urethane foam to be molded.

に巻き取られる。(Function) If the process paper according to the present invention is used as a carrier for urethane resin in the process of manufacturing urethane foam, the plastic film and the breathable base paper are in a temporarily attached state, so that the plastic film of the process paper Foaming is performed by foaming the urethane resin cast onto the film surface, and at this time, as shown in Figure 2, the foaming gas flows as shown by arrow A (flow of foaming gas). The gas is slowly released to the outside through the numerous micropores provided in the plastic film layer (as shown in Figure 3, in some cases, they penetrate through the air permeable base paper) and the air permeable base paper. , no foaming gas remains at the interface between the urethane foam and the plastic film layer, and therefore not only can a uniform foaming state be expected, but also the foaming of the urethane foam to be foamed and the plastic film surface of the process paper. It bonds strongly with heat, far exceeding the adhesive strength between the breathable base paper and the plastic film, and the adhesive strength between the plastic film and urethane foam of the process paper is almost negligible. As a result, as shown in FIG. 3, the plastic film 3 of the processing paper is adhesively transferred to the urethane foam 5 side in a thin film, and only the breathable base paper 2 is peeled off smoothly. roll 6
is wound up.

とができる利点もある。(Effects of the Invention) According to the process paper according to the present invention configured as described above, the foaming gas generated during foam molding of urethane foam is absorbed into the process paper (the pores of the plastic film and the air permeable base paper, or the plastic film). and micropores in both the air permeable base paper)
Since it is slowly diffused to the outside through the foam, uneven foaming caused by foaming gas remaining at the interface between the urethane foam and the plastic foam of the processing paper does not occur. In addition, the plastic film of the process paper adheres strongly to the foam-molded urethane foam, and the adhesive strength between the plastic film of the breathable base paper and the plastic film of the breathable base paper is relatively weak to the extent that it can be ignored. can also be peeled off smoothly. The micropores provided through the plastic film layer or both the plastic film and the breathable base paper in the process according to the present invention are large enough to exhibit breathability and at the same time prevent the urethane resin from seeping out to the back surface. Therefore, the air-permeable base paper can be reused without impregnating the air-permeable base paper with the urethane resin. Furthermore, the process paper according to the present invention has its air permeability and air permeability properties depending on the thickness and number of needle-like protrusions per unit area (projection density of the needle-like protrusions) protruding from the peripheral surface of the heat roll. Since the temporary adhesion force between the paper and the plastic film can be adjusted, there is also the advantage that the temporary adhesion force required depending on the type of plastic film targeted can be easily obtained.
