Shielding material for shielding radioactive rays, and preparation method thereof
The embodiment of the invention provides a shielding material for shielding radioactive rays. The shielding material is composed of water, a cementing material, a fine aggregate, a coarse aggregate and an additive, wherein the fine aggregate is composed of boron glass powder and barite sand, and the coarse aggregate is composed of lead stone and barite; the boron element content in the boron glasspowder is 0.5-1% of the total weight of the shielding material; the content of barium sulfate in the barite sand and barite accounts is 71-75% of the total weight of the shielding material; and the water, the cementing material and the additive account for the remaining percentage of the shielding material, and the total content of all the components is 100% of the total weight of the shielding material. The embodiment of the invention further provides a preparation method of the shielding material for shielding the radioactive rays.
本发明的实施例中提出一种用于屏蔽放射性射线的屏蔽材料，该屏蔽材料由水、胶凝材料、细骨料、粗骨料和外加剂组成，其中细骨料由硼玻璃粉和重晶石砂组成，粗骨料由铅石和重晶石组成；硼玻璃粉中的硼元素含量占屏蔽材料总重量的0.5％～1％；重晶石砂和重晶石中的硫酸钡含量占屏蔽材料总重量的71％～75％；其他含量为水、胶凝材料和外加剂，所有成分的含量总和为屏蔽材料总重量的100％。本发明的实施例中还提出了一种用于屏蔽放射性射线的屏蔽材料的制备方法。
