Problems solved by technology

[0003] In daily life, people are more exposed to electromagnetic radiation such as microwaves, ultraviolet rays, computer radiation, and other electromagnetic radiation. These electromagnetic radiations are harmful to the human body to varying degrees. Lighter, high-energy nuclear radiation is much more serious than electromagnetic radiation, especially the damage to the human body and the environment caused by gamma rays. Therefore, finding a safe and reliable protective material is crucial to the safety of radioactive workers. Therefore, the study of gamma-ray shielding materials has become a very important topic
[0004] Vanadium slag is a kind of industrial vanadium extraction raw material. The vanadium yield in the existing vanadium slag extraction process is low, energy consumption is high, environmental pollution is serious, and comprehensive utilization of vanadium slag is difficult. Therefore, the overall and efficient utilization of vanadium slag is a urgent problem
At present, there are no reports on the application of vanadium slag in the research of γ-ray shielding materials at home and abroad.

Embodiment 1

[0042] Embodiment 1 provides a kind of gamma ray shielding material, and this gamma ray shielding material is prepared by weight from the following components: vanadium slag (wherein, containing V 2 o 5 The mass fraction is 5.2%) 5 parts; Epoxy resin E518 parts; 651 polyamide resin 5 parts; Dehydrated alcohol 30 parts;

[0043] In addition, if figure 1 As shown, embodiment 1 also provides the preparation method of the above-mentioned γ-ray shielding material, and the specific steps are as follows:

[0044] S0, will contain V 2 o 5 The 5.2% (mass fraction) vanadium slag is ground and passed through a 100-mesh sieve to obtain pretreated vanadium slag.

[0045] S1, according to mass ratio epoxy resin E51:651 polyamide resin: vanadium slag is 8:5:5 to add and mix three kinds of materials, add mass ratio vanadium slag afterwards: dehydrated alcohol is the dehydrated alcohol (concentration) of 1:6 was 99.7%), mechanically stirred for 15 min, and mixed uniformly to obtain liquid...

Abstract

The invention discloses a gamma-ray shielding material, belonging to the technical field of shielding materials. The gamma-ray shielding material is prepared from the following components in parts by weight: 5-90 parts of vanadium slag, 5-8 parts of epoxy resin, 3-5 parts of a curing agent and 30-240 parts of a volatile diluent, wherein the epoxy resin is bisphenol A type epoxy resin, the curing agent is synthetic resin, and the volatile diluent is one or more of alcohol compounds, ketone compounds and aromatic compounds. According to the gamma-ray shielding material, the problem that vanadium slag is difficult to be comprehensively utilized in the past is solved, a new way is opened for the utilization of the vanadium slag, and a very cheap raw material is found for the production of a gamma-ray protecting material; and the gamma-ray shielding material has the characteristics of low cost, simplicity in production and operation, no secondary pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of shielding materials, and relates to a gamma-ray shielding material and a preparation method thereof. Background technique [0002] In the 20th century, my country's nuclear industry has made great progress, and radioisotopes and radiation devices are widely used in various industries. With the use of accelerators and reactors, the types of radioactivity that people are exposed to are gradually increasing. In addition to X and gamma rays, there are also charged particles such as neutrons, protons, and electrons. The chance of exposure to ionizing radiation is also gradually increasing. [0003] In daily life, people are more exposed to electromagnetic radiation such as microwaves, ultraviolet rays, computer radiation, and other electromagnetic radiation. These electromagnetic radiations are harmful to the human body to varying degrees. Lighter, high-energy nuclear radiation is much more serious than elect...
