摘要:

制备了质量分数3%、4%、5%及6%碳化硼以和不同厚度的碳化硼/铅/聚乙烯复合材料,并对碳化硼/铅/聚乙烯复合材料的热稳定性和屏蔽性能进行了研究。经测试可知: 当不同试样处于同一厚度时,添加质量分数6%碳化硼复合材料的高温基础性能较好; 热重测试表明,该试样的质量损失较低,有效保持了其基础性能。同时,添加质量分数为6%碳化硼的复合材料的应用效果最佳,具有较好的粒子屏蔽性能。该结果为碳化硼/铅/聚乙烯复合材料的制备和性能评估提供了可靠的依据。

Abstract:

The preparation, thermal stability and shielding properties of boron carbide/lead/polyethylene composites were studied. Boron carbide/lead/polyethylene composites with mass fraction of 3%, 4%, 5% and 6% boron carbide and different thicknesses were prepared, and the related properties of the composites were evaluated. The results show that when different samples are at the same thickness, adding 6% boron carbide composite has better high-temperature basic properties. Thermogravimetric test shows that the mass loss of the sample is low and its basic properties are effectively maintained. In addition, the composite with 6% boron carbide has the best application effect and better particle shielding performance. The results provide a reliable basis for the preparation and performance evaluation of boron carbide lead polyethylene composites.
