向上する。Furthermore, in the present invention, when the synthetic resin-impregnated paper is polymerized into a porous body, the porous body is reinforced and the shape retention and heat resistance are improved.
また更に本発明において多孔補強層を多孔質体に重合し
た場合も同様に多孔質体が補強されるが、多孔補強層の
場合は伸縮性が良好で成形形状に追随性が大であり、深
絞り成形等によっても亀裂等を生じない。Further, in the present invention, when the porous reinforcement layer is polymerized into a porous body, the porous body is similarly reinforced, but in the case of the porous reinforcement layer, the stretchability is good and the conformability to the molded shape is large, No cracks or the like are generated even by drawing.

(1) is a polyether type soft polyurethane foam sheet (density: 0.017 g / cm 3 , thickness: 5 mm), which is guided by a guide roll (2) and introduced into an immersion tank (3). The dipping tank (3) is filled with a 40% by weight trichloroethylene solution (9) of 4,4'-diphenylmethane diisocyanate (MDI) blocked by phenol, and the sheet is placed in the dipping tank (3). (1) was added to the solution by the compression rolls (4) and (5).
After being compressed twice, it is impregnated with the blocked MDI solution (9), and then it is discharged from the dipping tank (3) and the blocked MDI impregnation amount is about 100 g /
Adjusted to m 2 . The blocked MDI-impregnated sheet (1) A is then sent to a ventilation dryer (7) at 70 ° C., dried for 5 minutes, and then cut into an appropriate size by a cutter (8).
