Paraffin/boron carbide neutron protection composite material and preparation method thereof
The invention discloses a paraffin/boron carbide neutron protection composite material and a preparation method thereof, belongs to the technical field of nuclear protection materials, and solves the problems of incompact structure, boron carbide sedimentation and agglomeration and the like during preparation by adopting a casting method in the prior art. According to the preparation method of the paraffin/boron carbide neutron protection composite material, the content of paraffin in the neutron protection composite material is 1-60wt%, and the balance is boron carbide; and the neutron protection composite material is prepared by adopting a cold isostatic pressing method. Paraffin and boron carbide are creatively adopted as raw materials, and the neutron protection composite material is prepared through the cold isostatic pressing method. The paraffin/boron carbide neutron protection composite material disclosed by the invention is uniform in boron carbide distribution, compact in structure and excellent in performance, can have double functions of slowing down and absorbing of fast neutrons, slow neutrons and thermal neutrons, and meets neutron protection requirements of special occasions of spent fuel post-treatment.
本发明公开了一种石蜡/碳化硼中子防护复合材料及制备方法，属于核防护材料技术领域，解决现有技术中采用熔铸法制备时存在的组织不致密、碳化硼沉降团聚等问题。本发明的石蜡/碳化硼中子防护复合材料的制备方法，所述中子防护复合材料中石蜡含量为1‑60wt％，其余为碳化硼，采用冷等静压法制备。本发明创造性地采用石蜡、碳化硼为原料，采用冷等静压法制备得到中子防护复合材料。本发明的石蜡/碳化硼中子防护复合材料碳化硼分布均匀、组织致密、性能优异，可兼具快中子、慢中子和热中子慢化吸收双功能，达到乏燃料后处理特定场合的中子防护要求。
