Preparation method of carbon-carbon heater
The invention belongs to the technical field of carbon-carbon heaters, and particularly relates to a preparation method of a carbon-carbon heater. The preparation method of the carbon-carbon heater comprises the following steps: carrying out first vacuum filtration on a dispersion liquid of short carbon fibers in a mold, adding a mixed liquid of phenolic resin and ethanol into the mold, carrying out second vacuum filtration, demolding, curing and molding, dipping an obtained carbon-carbon heater blank in asphalt or phenolic resin, and carbonizing to obtain the carbon-carbon heater. The obtained carbonized blank is subjected to graphitization treatment, vapor deposition densification and purification treatment, and the carbon-carbon heater is obtained. Through vacuum filtration forming, manual knitting errors can be avoided, the uniformity of the product is better, and the conductivity of the prepared carbon-carbon heater is good. And meanwhile, large-batch production can be realized, the productivity is higher, the labor cost is saved, and time and labor are saved. The preparation method is low in raw material consumption, low in cost and convenient to operate, and the carbon-carbon heater is good in integrity, low in impurity content and good in conductivity and mechanical property.
本发明属于碳碳加热器技术领域，具体涉及一种碳碳加热器的制备方法。本发明碳碳加热器的制备方法，包括以下步骤：将短切碳纤维的分散液在模具中进行第一真空抽滤，在所述模具中再加入酚醛树脂与乙醇的混合液进行第二真空抽滤，脱模，固化成型，将得到的碳碳加热器坯体浸渍沥青或酚醛树脂、进行碳化，将得到的碳化坯体进行石墨化处理、气相沉积增密和纯化处理，得到碳碳加热器。本发明通过真空抽滤成型，能够避免人工编织误差，产品的均匀性更好，制得的碳碳加热器导电性能好。同时可实现大批量生产，产能更大，节约人工成本，省时省力。本发明的制备方法，原材料消耗少、成本低、操作方便，且碳碳加热器整体性好，杂质含量少，导电和力学性能好。
