Clustered mullite fiber attached with surface coating and preparation method of surface coating of clustered mullite fiber
The invention discloses a clustered mullite fiber attached with a surface coating and a preparation method of the surface coating of the clustered mullite fiber, and the preparation method comprises the following steps: preparing first coating slurry which comprises mullite sol; preparing second coating slurry, wherein the second coating slurry comprises a high-molecular polymer and silica sol; preparing third coating slurry, wherein the third coating slurry comprises an antistatic agent and a softener; the preparation method comprises the following steps: dipping a fiber bundle in first coating slurry and drying for the first time, then dipping in second coating slurry and drying for the second time, and then dipping in third coating slurry and drying for the third time to obtain clustered mullite fiber and a surface coating attached to the surface of the mullite fiber; according to the invention, the coating is attached to the surface of the mullite fiber, damage repair of the surface of the mullite fiber is realized, the bundled mullite fiber bundle does not fluff in the use process, and organic components in the coating are easy to remove at 300-600 DEG C before use.
本发明公开了附着表面涂层的集束莫来石纤维及其表面涂层制备方法，所述制备方法包括以下步骤:制备第一涂层料浆，所述第一涂层料浆包括莫来石溶胶；制备第二涂层料浆，所述第二涂层料浆包括高分子聚合物、硅溶胶；制备第三涂层料浆，所述第三涂层料浆包括抗静电剂、柔顺剂；纤维束浸渍第一涂层料浆和第一次干燥，然后浸渍第二涂层料浆和第二次干燥，再浸渍第三涂层料浆和第三次干燥，得到集束莫来石纤维以及附着在莫来石纤维表面的表面涂层；实现莫来石纤维表面附着涂层，实现莫来石纤维表面损伤修复，且集束后的莫来石纤维纤维束在使用过程中不会起毛，且涂层中的有机成分在使用前在300‑600℃下容易去除。
