Description
Technical Field
The invention belongs to the field of special neutron radiation protection engineering, in particular to a high-temperature-resistant high-boron glass sand neutron absorbing material and a preparation method thereof.
Background
Radiation protection is a basic component of nuclear industry technology, and along with the continuous development of the nuclear industry technology, special radiation protection plays an increasingly important role in the fields of national defense, scientific research and the like. Neutrons are uncharged particles which have stronger penetrating power than electrons and gamma rays, and cause more damage to human bodies than electrons, gamma rays and X rays at the same absorbed dose. At present, the neutron absorbing materials commonly used are hydrogen-containing materials such as paraffin, polyethylene and the like and boron-containing materials such as borax, boric acid and the like, wherein the use temperature of the former is generally not more than 120 ℃, and the mechanical property and the weather resistance of the latter are poor.
Glass materials are widely used due to good engineering properties, and glass materials made of boron-containing compounds can be used as neutron absorbers for different radiation protection scenes. For example, pbO-B 2O3-SiO2 glass and Bi 2O3-B2O3-SiO2 glass have good perspective effect and can be used as window materials with neutron shielding performance, but the content of the system glass B 2O3 is generally not more than 40wt percent, and the neutron absorption performance needs to be further improved; for example, the CdO-SiO 2-B2O3 glass has a higher low-energy neutron absorption section for both B element and Cd element, but the CdO as a glass raw material is toxic and cancerogenic, so that the glass raw material is not suitable for being used as engineering materials on a large scale; for example, the absorption cross section of rare earth elements doped with B 2O3 glass is ten times higher than that of B elements, but the rare earth elements are low in content and the raw materials are high in price, so that the rare earth elements are difficult to popularize and apply; for example, na 2O-B2O3 -ZnO glass, the mass content of B 2O3 can reach more than 60%, but the glass stability deviation is very easy to absorb moisture in the air, and the glass is not suitable for being used in environments with higher humidity.
The high-boron glass sand neutron absorbing material takes B 2O3 as a main raw material, and the content of B 2O3 is far higher than that of common boron-containing shielding glass, so that the high-boron glass sand neutron absorbing material has more excellent low-energy neutron absorbing performance than that of the boron-containing shielding glass. The particle size of the high-boron glass sand is uniformly adjustable within a certain size range, and the high-boron glass sand can be used as loose materials to be piled around instruments and equipment needing shielding protection, and can also be used as aggregate to be matched with concrete to be poured at key parts of a shielding structure, so that the neutron shielding protection safety is effectively ensured.
