Embodiment 1

[0029] Lead plate raw materials (parts by weight): 100 parts of lead powder, 7 parts of titanium dioxide, 1.5 parts of rare earth additives, and 3 parts of metal powder additives.

[0030] The rare earth additive is obtained by uniformly mixing praseodymium oxide, samarium oxide, and gadolinium oxide in a mass ratio of 1:1:1.

[0031] The metal powder additive is obtained by uniformly mixing yttrium powder, zirconium powder, and silver powder in a mass ratio of 1:1:1.

[0032] Lead plate preparation: Melt lead powder in a heating furnace at 400°C, then add titanium dioxide, rare earth additives, and metal powder additives to mix evenly, and then roll. The rolling start temperature is 310°C, and the final rolling temperature is 180°C, the rolling speed is 3m / s, cooling is performed after rolling, the cooling rate is 4°C / s, and the final temperature after cooling is 40°C. The thickness of the lead plate is 2mm, the length is 1000mm, and the width is 800mm.

[0033] The steel p...

Abstract

The invention discloses an anti-radiation lead-steel composite plate. The anti-radiation lead-steel composite plate is formed by welding a steel plate and a lead plate. The lead plate is prepared from the following raw materials in parts by weight: 95-105 parts of lead powder, 5-15 parts of titanium dioxide, 0.5-5 parts of a rare earth additive, and 1-10 parts of metal powder additive. The anti-radiation lead-steel composite plate is simple in structure, low in cost, energy-saving and environmentally friendly. The performance of a synthesized plate is excellent, radioactive ray protection performance is high, human body protection is facilitated, and the anti-radiation lead-steel composite plate facilitates people and is a practical anti-radiation material.

Description

technical field [0001] The invention relates to the technical field of radiation-proof lead glass, in particular to a radiation-proof lead-steel composite plate. Background technique [0002] With the rapid development of industrial and agricultural production, national defense scientific research, radiation medicine and atomic energy industry, the use of various rays is becoming more and more extensive. While using rays, we should also pay attention to the harmfulness of rays. The effect of radiation on biological organisms, or the biological effects of radiation, is mainly due to the interaction between radiation and water molecules in the body to produce a strong oxidant, which further interacts with the body to produce a series of biochemical effects (such as making the body Oxidation of many macromolecules). The biological effects caused by direct ionization and excitation of rays to the body are not serious. Generally speaking, there are two aspects to the harm of r...
