High-temperature coating of carbon fiber thermal insulation material
The invention discloses a high-temperature coating of a carbon fiber thermal insulation material in the technical field of single crystal furnaces, and the high-temperature coating of the carbon fiber thermal insulation material is formed by stirring phenolic glue, epoxy glue, graphite powder and ethylene glycol in vacuum, the use method of the high-temperature coating of the carbon fiber thermal insulation material comprises the following steps: stirring the phenolic glue, the epoxy glue, the graphite powder and the ethylene glycol in a vacuum stirrer to prepare a first coating; mixing phenolic glue and water to prepare an aqueous solution of the phenolic glue, blade-coating the surface of the carbon fiber thermal insulation material with the aqueous solution of the phenolic glue, and drying and hardening; the first coating in the step S1 is evenly smeared on the surface of the aqueous solution of the phenolic glue dried and hardened in the step S2, curing in a drying oven is prevented, according to the high-temperature coating of the carbon fiber heat preservation material, a compact coating is formed on the carbon fiber material, the coating can not crack or fall off slag at the temperature of 1800 DEG C, the oxidation resistance is high, and the service life of the coating is prolonged. And the service life of the product is greatly prolonged.
本发明公开了单晶炉技术领域的一种碳纤维保温材料的高温涂层，该碳纤维保温材料的高温涂层是由酚醛胶、环氧胶、石墨粉和乙二醇真空搅拌而成，该碳纤维保温材料的高温涂层的使用方法：将酚醛胶、环氧胶、石墨粉和乙二醇置于真空搅拌机中进行搅拌，制成一号涂料；将酚醛胶和水混合制成酚醛胶的水溶液，酚醛胶的水溶液刮涂在碳纤维保温材料表面并进行烘干硬化；将步骤S1中的一号涂料均匀涂抹在步骤S2中烘干硬化后的酚醛胶的水溶液的表面，防止烘箱中进行固化，该种碳纤维保温材料的高温涂层，通过在碳纤维材料形成一层致密的涂层，该涂层能够在1800℃下不开裂掉渣，且抗氧化性能强，大大增强产品的使用寿命。
