Problems solved by technology

[0004] When commonly used indoor building materials are used for radiation protection, heavy materials such as barite and serpentine are generally added to increase the density of the wall, thereby improving the wall material to weaken and prevent the harm of radiation rays, but for For the wall material of the partition wall and the suspended ceiling, the density is too high to be convenient for construction, and the product is easy to deform, which poses a great safety hazard

preparation example Construction

[0025] There is no special limitation on the specific preparation method, and each component can be weighed and stirred according to a conventional method to obtain a mixed gypsum slurry.

[0026] Since zeolite is a frame-like silicate structure composed of relatively open silica and alumina tetrahedrons, the tiny channels in zeolite are uniform and fixed in size, substances smaller than its diameter can be adsorbed, and substances larger than its diameter can be adsorbed. There is no adsorption effect, which plays a screening role for molecules. In addition, the surface of zeolite has strong tolerance and strong electrostatic force, because cations are distributed in the lattice holes, and some of the lattice oxygen also have negative charges, thus forming a strong electric field around the ions , so its adsorption capacity is particularly strong, and its adsorption capacity for radon gas is relatively good. Thus, the radon-proof and radiation-proof board of the present inve...

Abstract

The invention discloses a preparation method of a radon-proof radiation-proof plate. The method includes the following steps: a) preparing gypsum slurry containing gypsum powder, water and radon-proof radiation-proof mineral powder with zeolite powder; b) pouring 1 / 3-2 / 3 of total gypsum slurry into a lower mould coated with a release agent and arranging a radiation-proof metal net on the surface of the slurry; c) pouring surplus gypsum slurry into the place above the radiation-proof metal net, covering an upper mould plate coated with the release agent and compacting the slurry by vibration to conduct molding; and d) conducting demoulding to conduct natural airing to obtain the radon-proof radiation-prof plate. By means of the preparation method of the radon-proof radiation-proof plate, wall body density is reduced, and danger caused by wall body deformation is reduced. In addition, the radon-proof radiation-proof plate has excellent radon-proof radiation-proof performance due to the added radon-proof radiation-proof plate.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a preparation method of a radon-proof and radiation-proof board. Background technique [0002] At present, people pay more and more attention to the radiation pollution in the living environment. [0003] A large number of nuclear reactions such as α, β, γ, X-rays and neutrons can induce cancer, leukemia and multiple myeloid cancer, thyroid dysfunction, infertility and birth defects and other human terminal diseases, as well as induce plant gene mutations , Harm the growth of crops. In fact, due to the low penetrating power of α-rays and β-rays, they are easily absorbed, and even protective materials with a small thickness can completely block them, so the problem of radiation protection is mainly attributed to the protection of γ-rays and neutron flow. [0004] When commonly used indoor building materials are used for radiation protection, heavy materials such as ba...
