| titleOfInvention | Method for producing polypropylene-based resin foam |
| abstract | (57) [Summary] [Object] To provide a method capable of producing a polypropylene resin crosslinked foam having improved skin strength. According to the method of the present invention, a foamable resin composition containing a polypropylene-based resin, a thermal decomposition type foaming agent and a crosslinking aid is crosslinked, and then heating is performed stepwise from the low temperature side to the high temperature side. The foaming is carried out in the liquid phase or the gas phase. When the heating is performed in the liquid phase, the first heating is performed in the temperature range of −10 to + 20 ° C., and then the second heating is performed in the temperature range of +20 to + 60 ° C. based on the decomposition point of the thermal decomposition type foaming agent. To do. When the heating is performed in the gas phase, the first heating is performed in the temperature range of +20 to + 50 ° C, and then the second heating is performed in the temperature range of +50 to + 200 ° C. |
