摘　　要：研究了煅后无烟煤粉通过物理法研磨处理和化学氧化改性代替炭黑作为橡胶补强剂,考察了煤粉的粒径、煤粉与橡胶的质量比及温度对补强效果的影响。实验结果表明,煤粉分别经物理法研磨处理和化学氧化改性均可作为橡胶补强剂,在结合温度为50℃时,补强橡胶的结合胶量分别为27.83%和29.04%,但补强效果较N660和N330稍差。In this paper,the modified calcined anthracite powder instead of carbon black was used as rubber reinforcing agent by physical grinding processing method and chemical oxidation, to analyze of the influences of the particle size of coal, coal-rubber wt ratio, reaction temperature. Results showed that coal by physical grinding processing method and chemical oxidation can be used as rubber reinforcing agent,and in 50 ℃ ,the combination of reinforced rubber glue were 27.83% and 29.04% respectirely, but the reinforcing effect was slightly worse than carbon black N660 and N330.
