摘要： A high-polymer neutron shielding material which scarcely reduces the hydrogen number density when exposed to a high temperature of 150 to 200°C for a long time period
A heat-setting type epoxy resin is employed. The base resin is selected from various epoxy resins such as bisphenol A type epoxy resin. The hardener is selected from alicyclic polyamine, polyamide amine, aromatic polyamine, acid anhydride, and so on. These materials are mixed and hardened at a temperature higher than the room temperature. To give a flame resistance to the hardened resin, a fire retardant such as magnesium hydroxide is added to the mixture. To improve the neutron shielding performance of the hardened resin, a neutron absorbing material is added to the mixture. Further, to increase the moderating performance, hydrogenated bisphenol A epoxy resin is used as the base resin or metal hydride or hydrogen absorbing alloy is added. The present neutron shielding material works as a significant neutron shielding material as its hydrogen number density does not go down for a long time under a high-temperature condition and the neutron shielding performance does not go down.
摘要翻译：高分子中子屏蔽材料，当长时间暴露于150〜200℃的高温时，几乎不降低氢数密度。采用热固型环氧树脂。基础树脂选自各种环氧树脂如双酚A型环氧树脂。固化剂选自脂环族多胺，聚酰胺胺，芳香族多胺，酸酐等。这些材料在高于室温的温度下混合和硬化。为了赋予硬化树脂耐火性，向混合物中加入阻燃剂如氢氧化镁。为了提高硬化树脂的中子屏蔽性能，向混合物中加入中子吸收材料。此外，为了提高调节性能，使用氢化双酚A环氧树脂作为基础树脂，或者添加金属氢化物或吸氢合金。本中子屏蔽材料作为重要的中子屏蔽材料起作用，因为其氢数密度在高温条件下长时间不会下降，并且中子屏蔽性能不会下降。
