Preparation method of carbon ceramic heater and prepared carbon ceramic heater
The invention relates to the field of carbon-ceramic composite materials, and particularly discloses a preparation method of a carbon-ceramic heater and the prepared carbon-ceramic heater, and the preparation method comprises the following steps: S1, taking short carbon fibers, a dispersing agent, a binder, ceramic powder and liquid phenolic resin as raw materials, mixing and stirring to prepare a raw stock mixture; s2, carrying out mixing and mould pressing on the primary pulp, and heating and curing to obtain a preformed body; s3, carrying out carbonization treatment on the preformed body in the step S2 to obtain a preformed blank; s4, sequentially carrying out densification treatment and graphitization treatment on the prefabricated blank prepared in the step S3, and then machining to prepare the carbon-ceramic heater; the invention further discloses the carbon-ceramic heater manufactured through the method. The carbon-ceramic composite material has the characteristic of improving the resistance stability of the heater prepared from the carbon-ceramic composite material.
本申请涉及碳陶复合材料领域，具体公开了一种碳陶加热器的制备方法及制得的碳陶加热器，制备方法包括以下步骤：S1、以短切碳纤维、分散剂、粘结剂、陶瓷粉和液体酚醛树脂为原料混合搅拌，制得原浆混料；S2、将原浆混料模压、加热固化后制得预成型体；S3、将步骤S2中的预成型体进行碳化处理，得到预制坯体；S4、将步骤S3中制得的预制坯体依次进行增密处理、石墨化处理后机加工，制得碳陶加热器；本申请还公开了采用上述方法制得的碳陶加热器。本申请具有提高碳陶复合材料制得加热器的电阻稳定性的特点。
