Abstract

The invention discloses an epoxy-resin-based neutron shielding material and a method for preparing the same. The epoxy-resin-based neutron shielding material is prepared from epoxy resin matrix composite boron carbide fillers. Epoxy resin for the epoxy-resin-based neutron shielding material is o-cresol-formaldehyde epoxy resin, a curing agent is phenolic resin, and a curing accelerator is imidazole or an imidazole compound. The epoxy-resin-based neutron shielding material and the method have the advantages that the epoxy-resin-based neutron shielding material which is an epoxy resin / boron carbide composite material prepared by the aid of the method is excellent in neutron shielding performance; processes are easy to operate and popularize and low in cost.

Description

technical field [0001] The invention relates to the technical field of neutron shielding materials, in particular to an epoxy resin-based neutron shielding material and a preparation method thereof. Background technique [0002] Neutrons are one of the basic particles that make up the atomic nucleus. They are not electrically charged, but because they have a strong penetrating ability in materials, they are widely used in the fields of national defense, scientific research, nuclear power, medical treatment and detection. However, neutron irradiation will cause damage such as defects and dislocations inside the material, resulting in degradation of material properties. At the same time, a large number of secondary particles produced by the displacement effect of neutrons will interact with tissue cells, thereby posing a huge threat and damage to human health. Therefore, it is of great practical significance to develop neutron shielding materials with excellent comprehensive ...
