Abstract
一种用于土壤源跨季节储热填充的SiC导热材料，涉及新能源利用与热能储存的交叉技术领域。本发明的目的是提供一种用于土壤源跨季节储热填充的SiC导热材料，以解决SiC导热材料制备过程中存在原料成本高，难以大规模应用等问题。技术要点：将褐煤粉碎筛选褐煤粉末再进行酸洗，将酸洗后的溶液进行过滤得到除杂后的褐煤粉末，用流动的水洗去粉末上残留的盐酸，最后对水洗后的粉末烘干处理；将褐煤粉末、稻壳粉末、煤矸石粉末进行混合，在氩气保护下在石墨坩埚中进行24～30h高温碳化反应，反应温度为1200℃～1300℃，反应完成后冷却48h～50h；将冷却后的反应产物粉碎至4mm～5mm，作为地埋管回填材料的原料。本发明所采用工艺原料成本低，能大规模应用。本发明以低成本的方式制备了适用于提高跨季节储热地埋管回填材料导热性的碳化硅材料，原材料为低品位能源，复合环保要求，促进资源的再利用。
