Anti-neutron radiation material and preparation method thereof

Abstract

The invention provides a neutron radiation-proof material and a preparation method thereof. By adding rectorite, it has solidified nuclide, is not easy to flocculate, and is anti-cracking, and is an ideal radiation-proof material. ), Sr(II), Eu(III), and U(VI) have excellent curing effects. In addition, they have the functions of preventing neutrons, X-rays, and γ-rays; by adding Portland cement clinker, the compression resistance, The flexural strength improves durability and practicability; by adding dihydrate gypsum, the setting time can be adjusted, which is convenient for construction; the preparation method of the anti-neutron radiation material disclosed by the invention is simple in process, low in cost, easy in construction, and does not affect ordinary silicic acid Salt cement performance, can be widely used as anti-ray building materials in civil buildings.

Description

technical field [0001] The invention relates to the field of neutron radiation protection, in particular to a neutron radiation protection material and its preparation method and application. Background technique [0002] Nuclear power is of great strategic significance to break through the bottleneck of my country's energy shortage development; however, the Fukushima nuclear power plant accident in 2011 made my country have to comprehensively review nuclear safety issues again; and the safe use of nuclear energy is highly dependent on reliable radiation-proof materials; therefore, the performance of radiation-proof materials The basic technology is the fundamental issue of improving my country's energy supply structure, ensuring energy security and economic security! What radiation protection needs to shield are α, β, γ, X-rays and neutron flow. Neutrons are electrically neutral, have strong penetrating power, and pose the greatest threat of radioactive hazards.

AI Technical Summary

Problems solved by technology

[0003] At present, neutron radiation shielding materials mainly include two types: (1) synthetic materials, carbon-boron-containing polyethylene, boron-containing epoxy resin, boron carbide, zirconium hydride, etc., these materials are high in cost and difficult to form; (2) natural materials , barite, limonite, witherite and other large specific gravity minerals, the use of this material requires the introduction of steel forging to make the protective body too heavy, resulting in many problems such as easy segregation, easy cracking, and poor durability. Limestone, hard boron calcium Stone, pumice, etc. are used as mineral admixtures, but the anti-neutron radiation effect is poor
