Problems solved by technology

Due to the large proportion of lead and cadmium, the anti-radiation equipment prepared by it is very heavy, and the more important thing is that lead and cadmium are toxic substances, which will not only pollute the environment in the production process, but also cause harm to the health of operators. harm
In addition, due to the variety of radiation, lead and cadmium have better protection ability to gamma rays, but weaker protection ability to high-energy neutrons

Abstract

The invention discloses an anti-nuclear radiation composite material capable of protecting high-energy neutrons and gamma rays properly. The composite material comprises a pair of stainless steel substrates. One side surface of each stainless steel substrate is provided with at least two high-energy neutron protective coatings, and the other side surface of the stainless steel substrate is provided with at least one gamma ray protective coating so that anti-nuclear radiation panels are formed. The innermost coating in the high-energy neutron protective coatings comprises, by weight, 40-70 parts of aluminum-based metal, 20-40 parts of boron carbide and 10-20 parts of samarium oxide, and the outermost coating comprises, by weight, 30-70 parts of the aluminum-based metal, 20-50 parts of aluminum fluoride and 10-20 parts of zirconium hydride. The sides, provided with the gamma ray protective coatings, of the anti-nuclear radiation panels are combined together back to back. The composite material can be widely used for making nuclear radiation protection devices.

Description

technical field [0001] The invention relates to a composite material, in particular to an anti-nuclear radiation composite material. Background technique [0002] People in the industry know that traditional anti-nuclear radiation materials usually include heavy metals such as lead and cadmium. Due to the large proportion of lead and cadmium, the anti-radiation equipment prepared by it is very heavy, and the more important thing is that lead and cadmium are toxic substances, which will not only pollute the environment in the production process, but also cause harm to the health of operators. harm. In addition, because there are many types of radiation, lead and cadmium have better protection ability to gamma rays, but weaker protection ability to high-energy neutrons. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-nuclear radiation composite material that can better protect high-energy neutrons and gam...
