Heat insulation coating material for czochralski furnace, heat insulation thermal field and preparation method of coating

Abstract

The invention relates to the technical field of heat preservation coatings of heat preservation furnaces, and discloses a heat preservation coating material for a czochralski furnace, a heat preservation thermal field and a preparation method of a coating. The coating material comprises the following components: graphite powder and a graphite powder dispersing agent, the graphite powder can be dispersed in the graphite powder dispersing agent to form a viscous liquid, and the viscous liquid can be conveniently coated on a heat preservation felt used by the Czochralski furnace. The material is coated on the soft felt to form the heat preservation coating, and the effects of heat preservation, reduction of the heating power of the czochralski furnace and wear resistance are achieved.

本发明涉及保温炉保温涂层技术领域，公开了一种用于直拉炉的保温涂层材料、保温热场及涂层的制备方法。所述涂层材料包括以下组分：石墨粉和石墨粉分散剂，所述石墨粉可分散于所述石墨粉分散剂中，形成粘稠状液体，便于涂覆到直拉炉使用的保温毡上，在本发明中是涂覆到软毡上，以便形成保温涂层，起到保温、降低直拉炉加热功率以及耐磨损的作用。
