摘　　要：利用特种煤粉与热塑性塑料共混制取ＰＥ、ＰＰ、ＰＶＣ等共混材料，观察了煤粉通过化学处理和／或热处理制取的共混材料性能及微观结构。当处理过的煤粉质量分数达到４０％时，共混材料拉伸强度降低５％～２０％，而用同样质量分数的未处理煤粉，拉伸强度降低３０％～５０％Blends of PE,PP and PVC filled with special coal powder were prepared and the micro structure of the blends filled with chemically or/and thermally treated coal powder were studied.When the content of treated coal powder was up to 40%(by mass part),the tensile strength of the blend decreased 5%～20%,while the tensile strength of the blend filled with same amount of non treated coal powder decreased 30%～50%.
