Dopamine modified resin coating quartz fiber ceramic as well as preparation method and application thereof
The invention discloses a dopamine modified resin coating quartz fiber ceramic as well as a preparation method and application thereof. The preparation method comprises the following steps: S1, dipping a quartz fiber ceramic block in a buffer solution, and reacting to obtain ceramic loaded with polydopamine; in the buffer solution, the dosage of the dopamine hydrochloride is 1-2.5%; and S2, loading silicon-containing aryne resin on the surface of the ceramic loaded with the polydopamine. The dopamine is introduced into the interface of the quartz fiber ceramic and the silicon-containing aryne resin, so that the problem of poor adhesion of the interface of the quartz fiber ceramic and the silicon-containing aryne resin is solved, the polarity of the silicon-containing aryne resin is increased, the interface bonding strength is improved, and the dopamine-modified resin coating quartz fiber ceramic has excellent mechanical properties, moisture resistance, heat resistance, dielectric properties and the like, and can be used for preparing the silicon-containing aryne resin coating. The wave-transparent coating can be applied to the field of aerospace as a novel wave-transparent coating.
本发明公开了一种多巴胺改性的树脂涂层石英纤维陶瓷及其制备方法、应用。其制备方法包括下述步骤：S1将石英纤维陶瓷块浸渍于缓冲溶液中，反应得负载有聚多巴胺的陶瓷；缓冲溶液中，盐酸多巴胺用量为1‑2.5％；S2在负载有聚多巴胺的陶瓷表面负载含硅芳炔树脂即可。本发明将多巴胺引入到石英纤维陶瓷和含硅芳炔树脂界面，改善两者界面粘合性差的问题，增加硅芳炔树脂极性，提高界面结合强度，这种多巴胺改性的树脂涂层石英纤维陶瓷具有优良的力学性能、防潮性能、耐热性能和介电性能等，可作为一种新型的透波涂层应用到航空航天领域。
