摘　　要：为提高无水炮泥的综合使用性能,本文以刚玉、碳化硅、焦粉、氧化铝、白泥等为主要原料,加入酚醛树脂作结合剂,并分别引入0~3%的氮化硼作抗氧化剂,制得无水炮泥材料,再将样品分别经不同温度煅烧后检测其性能指标。结果显示:随着氮化硼加入量增加,材料的塑性变差,但经不同温度热处理后的材料体积密度变好,耐压强度及高温抗折强度均逐渐增强,呈现出不断变好的趋势。In order to improve the comprehensive performance of anhydrous gun mud,this paper presents the preparation of anhydrous gun mud using corundum,silicon carbide,coke breeze,alumina,and white mud,etc.as main raw materials,phenolic resin as the binder,and by introducing 0~3%boron nitride as the antioxidant.The performance indexes of the samples are then tested after calcination at different temperatures.The results show that as the increase of boron nitride added,the plasticity of the material deteriorates,but the volume density of the material becomes better after heat treatment at different temperatures.Meanwhile,the compressive strength and high-temperature flexural strength are gradually increased,showing a trend of continuous improvement.
