Beschreibung
Zusammenfassung:	The invention provides a high-temperature-resistant modified polyvinyl shielding material which is prepared from the following raw materials in parts by weight: 10-12 parts of high-density polyethylene, 6-8 parts of graft-modified ultra-high molecular weight polyethylene, 80-85 parts of radiation shielding substances and 0.5-3 parts of processing aids. The high-temperature-resistant modified polyvinyl shielding material can tolerate a high temperature of 190 DEG C or above under a medium-break water loss accident, can still maintain the integrity of a shielding structure and the effectiveness of shielding protection, and is a good radiation shielding material for a nuclear island area of a reactor of a nuclear power station. The material is applied to multiple nuclear power stations for test verification, and it is proved that the high-temperature-resistant modified polyvinyl shielding material can completely meet the radiation protection design requirements of the nuclear power stations in the whole service
