| titleOfInvention | Panel manufacturing method |
| abstract | The present invention provides a method for producing a rigid polyurethane sandwich panel that has good surface smoothness at the center of the panel surface, can prevent dents due to shrinkage of the corners, and can prevent appearance defects. A panel manufacturing method for supplying a stock solution composition into a cavity formed by a bottom surface material, a top surface material, and a frame member disposed between the bottom surface material and the top surface material. The gel time (Tg) and the filling time (seconds) for foaming and filling the cavity after the stock composition is supplied to the cavity (Tf) satisfy 2 ≦ Tg−Tf ≦ 15 (seconds), The just pack density (djp) of the rigid polyurethane foam and the density of the filled foam (dp) constituting the panel satisfy 110 ≦ 100 (dp / djp) ≦ 130 (%), and the gas venting hole is located near the corner of the frame material. 17 is formed, and the cross-sectional area of the vent hole is a total of 15 mm 2 or more per corner.
