Abstract

The invention discloses a leadless X-ray protection plate, which is prepared from the following materials in parts by weight: 40-50 parts of barium sulfate, 30-45 parts of barium-containing sulphoaluminate cement, 16-18 parts of reinforced fiber, 5-10 parts of mica powder, 2-5 parts of alumina powder, 2-5 parts of titanium pigment, 2-3 parts of zinc oxide and 2-5 parts of adhesive. The invention also discloses a preparation method of the leadless X-ray protection plate, which enhances the strength of the protection plate and improves the performance of the protection plate. The protection plate enhances the protection effect, is light in specific gravity, and simultaneously improves the performance of the protection plate, such as service life, strength and the like.

Description

technical field [0001] The invention relates to an X-ray radiation protection material and a preparation method thereof, in particular to a lead-free X-ray protection board and a preparation method thereof. Background technique [0002] With the development of modern science, all kinds of radiation as a new technology have been widely used in various fields of the national economy, especially in the fields of medicine, scientific research, and industrial flaw detection, which have extremely significant application value. In order to prevent these rays from harming the human body, people's research on radiation protection is also constantly developing. [0003] The traditional radiation protection material is lead, but due to the large specificity of pure lead, the mechanical properties are not good and the texture is soft. Although other metal materials are used as lining brackets and then coated with lead plates, the original plan is easy to deform, sag, not shockproof, an...
