Abstract
The invention provides a radiation-proof polyvinyl chloride material. The radiation-proof polyvinyl chloride material is prepared from the following raw materials in parts by mass: 15-25 parts of polyvinyl chloride, 5-15 parts of rare earth oxide, 15-25 parts of tungsten oxide powder, 20-40 parts of barium sulfate powder, 0.5-2 parts of a silane coupling agent, and 10-30 parts of an addition agent, wherein the rare earth oxide is one kind or a mixture of several kinds of samarium oxide, neodymium oxide and erbium oxide. According to the radiation-proof polyvinyl chloride material disclosed by the invention, the rare earth oxide, the tungsten oxide and the barium sulfate are used as radiation-proof components, and the polyvinyl chloride is stuffed, so that the radiation-proof polyvinyl chloride material is prepared. The radiation-proof polyvinyl chloride material has excellent radiation-proof properties.
