高强度抗热震性能电极糊以及制备方法
摘要：
一种高强度抗热震性能电极糊，其特征在于：由下列原料制备而成，均为重量比：15～20%电煅无烟煤、20～25%残极、35～40%煅后沥青焦、20～25%粘结剂，本发明中，粉料完全采用煅后沥青焦；煅后沥青焦具有相对价格低、灰分低、质量稳定性好并且硫含量低等优点，沥青焦焙烧后焦化程度好，结焦强度高，与粘结剂之间的热膨胀系数差异小致使产品抗热震性能强且对产品抗压强度提升较高，本发明还提出了一种高强度抗热震性能电极糊的制备方法。
摘要（英）：

Electrode paste with high strength and thermal shock resistance is characterized by being prepared from the following raw materials in percentage by weight: 15-20% of electrically calcined anthracite,20-25% of a residual electrode, 35-40% of calcined asphalt coke and 20-25% of a binder., powder completely uses the calcined asphalt coke; the calcined asphalt coke has the advantages of low relativeprice, low ash content, good quality stability, low sulfur content and the like; the calcined asphalt coke has good coking degree, high coking strength and small difference in thermal expansion coefficient with the binder, so that the product has strong thermal shock resistance and higher compression strength to the product; and the invention also provides a preparation method of the electrode paste with high strength thermal shock resistance.
