Beschreibung
Zusammenfassung:	The invention discloses a PVC (Polyvinyl Chloride) rigid foaming material and a preparation method thereof. The PVC rigid foaming material has a crosslinking structure formed by the PVC self and does not have the crosslinking structure formed by network systems of other high polymers. The PVC rigid foaming material is formed by heating and foaming a blending modified PVC resin and various auxiliary agents after electron irradiation. Because the PVC forms the crosslinking structure per se by an irradiation method, the network structure of other polymer systems is not needed to be introduced, thereby reducing material costs, simplifying production process and improving production efficiency.
