Abstract

The invention relates to a method for preparing a boron, lead and aluminum composite board preventing X rays, gamma rays and neutron irradiation to overcome the defect that a nuclear radiation and ray shielding material is single in shielding property. According to the method, aluminum powder, boron carbide powder and lead powder serve as raw materials, ball grinding, powder processing, material mixing, microwave heating, vacuum hot pressing blank stamping, and heating rolling forming are carried out, and then the boron, lead and aluminum composite board is prepared. The preparing method is advanced in technology, data are accurate and detailed, the prepared boron, lead and aluminum composite board has a good ray and neutron irradiation shielding effect, the X-ray shielding rate is larger than or equal to 95 percent, the gamma-ray shielding rate is larger than or equal to 40 percent, the neutron absorptivity is larger than or equal to 90 percent, boron carbide is evenly distributed, particles and a base body are combined tightly, high mechanical strength is achieved, the surface microhardness reaches 186.3 HV, the bending angle is larger than or equal to 15 degrees, the tensile strength is 305 MPa, the elongation after fracture is larger than or equal to 6 percent, the mechanical property and the shielding property of the boron, lead and aluminum composite board are improved, and the boron, lead and aluminum composite board can be used for single irradiation protection and can also be used for various types of radiation protection.

Description

technical field [0001] The invention relates to a preparation method of a boron-lead-aluminum composite plate for protecting X, gamma rays and neutron radiation, and belongs to the technical field of preparation and application of radiation protection and nuclear radiation protection materials. Background technique [0002] Nuclear energy has become one of the most potential energy sources in the world today. Nuclear fuel and spent fuel in nuclear power plants will produce harmful X, gamma rays and neutron radiation during use, storage and transportation. Therefore, shielding materials are used to protect The shielding of harmful rays has become a key problem that must be solved in the process of nuclear energy utilization. [0003] At present, the shielding materials for nuclear fuel and spent fuel mainly include lead-boron polyethylene, lead-based boron carbide composite materials, and boron stainless steel materials; lead element has a better shielding effect on X and gam...
