Silicon nitride fiber surface treating agent as well as preparation method and application thereof
The invention belongs to the technical field of silicon nitride fiber surface treatment, and particularly relates to a silicon nitride fiber surface treatment agent and a preparation method and application thereof. The surface treating agent comprises the following raw materials in parts by weight: 20-40 parts of polytetrafluoroethylene, 4-12 parts of an impregnating compound and 4-12 parts of a lubricating agent, and the lubricating agent is selected from one or more of polyethylene wax, silicone oil, dimethyl silicone oil, polyphthalamide, trimethylolpropane oleate, glyceryl trioleate, 2-ethylhexyl acrylate and 2-ethylhexyl methacrylate. The prepared surface treating agent can effectively act on the silicon nitride fibers under the synergistic effect of the lubricant and the impregnating compound, the bundling property, the wear resistance, the stiffness and the bending resistance of the silicon nitride fibers after secondary sizing are improved, the weaving performance requirements of the silicon nitride fibers are met, the technology is simple, the cost is low, and the surface treating agent is suitable for industrial production and has wide application prospects. The method can be widely applied.
本发明属于氮化硅纤维表面处理技术领域，具体涉及一种氮化硅纤维表面处理剂及其制备方法和应用。所述表面处理剂的原料包括聚四氟乙烯20‑40份、浸润剂4‑12份和润滑剂4‑12份，所述润滑剂选自聚乙烯蜡、硅油、二甲基硅油、聚邻苯二甲酰胺、三羟甲基丙烷油酸酯、三油酸甘油酯、丙烯酸异辛酯和甲基丙烯酸异辛酯中的一种或多种。本发明制备的表面处理剂在润滑剂和浸润剂组分的协同作用下能够有效作用于氮化硅纤维，二次上浆后氮化硅纤维的集束性、耐磨性、硬挺度、耐弯折性均得到改善，达到了氮化硅纤维的织造性能要求，工艺简单，成本低，适合工业化生产，可以广泛应用。
