Problems solved by technology

[0004] At present, the materials used for β, X and γ-ray radiation protection are generally not effective; and imported radiation shielding materials are expensive and have a long import delivery cycle, which is difficult to meet the needs of military and civilian ionizing radiation protection building materials
Especially the radiation protection construction of the ceiling is difficult, because as the thickness increases, the weight also increases relatively, and it is easy to crack and fall off

Abstract

The invention discloses an environmentally-friendly ionizing radiation protection seamless masonry brick. The brick comprises a brick body and a radiation protection coating layer which is painted onthe outer surface of the brick, the radiation protection coating layer is prepared by mixing and stirring a dry powder and water according to a weight ratio of 1:0.1, and the dry powder comprises, byweight, 2-6 parts of rectorite, 35-55 parts of a barium salt, 5-20 parts of vermiculite, 15-25 parts of iron powder, 3-8 parts of zeolite, 3-8 parts of ferric oxide and 5-15 parts of high-alumina silicate. The brick has the advantages of high density, large specific gravity, high viscosity, no cracking, simplicity in construction, and good radon, gamma-ray and X-ray radiation resistance.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to an environment-friendly seamless masonry brick for ionizing radiation protection. Background technique [0002] In building masonry structures, masonry bricks are the main load-bearing materials. Now, masonry bricks widely used in engineering include: solid clay bricks, concrete solid bricks, lime sand bricks, fly ash bricks, etc. These After being fired, masonry bricks have great strength and rigidity. They can be used not only as the main load-bearing structure, but also as a decorative structure. It has a wide range of uses. [0003] At present, in construction engineering, more and more attention is paid to building protection, especially high temperature protection. However, so far, ionizing radiation protection has not been truly realized and has been widely promoted. At the same time, with the development of science and technology, various high-energy rays ...
