XU NANA / MIAO LIYAN / MIAO LILI

The invention relates to a self-lubricating sizing agent for zirconium oxide fiber weaving and a preparation method of the self-lubricating sizing agent. According to the technical scheme, the preparation method comprises the following steps: uniformly mixing 25-34 parts by mass of an epoxy resin modified waterborne polyurethane emulsion, 6-9 parts by mass of an active auxiliary agent, 13-19 parts by mass of polyoxyethylene stearate, 2-5 parts by mass of vanadium pentoxide, 35-47 parts by mass of zirconium sol and 1.5-4.5 parts by mass of a mixed regulator, reacting in an oil bath, cooling, and carrying out high-speed shearing emulsification for 2.5-3 hours under the condition of 1150-1200r/min, so as to obtain a finished product. The self-lubricating sizing agent for zirconium oxide fiber weaving is obtained. The self-lubricating sizing agent has the characteristics of low cost, simple process and environmental friendliness, the prepared self-lubricating sizing agent woven by the zirconium oxide fibers is high in wear resistance, breaking strength and shearing performance, the phenomena of broken filaments and broken filaments are remarkably improved, the stability of a product in a three-dimensional texture is comprehensively improved, and the self-lubricating sizing agent has good biodegradability.

本发明涉及一种用于氧化锆纤维编织的自润滑上浆剂及其制备方法。其技术方案是：将25～34质量份的环氧树脂改性水性聚氨酯乳液、6～9质量份的活性助剂、13～19质量份的聚氧乙烯硬脂酸脂、2～5质量份的五氧化二钒、35～47质量份的锆溶胶和1.5～4.5质量份的混合调节剂混合均匀，放置油浴中反应，降温，再于1150～1200r/min条件下高速剪切乳化2.5～3h，得到用于氧化锆纤维编织的自润滑上浆剂。本发明具有成本低、工艺简单和环境友好的特点，所制备的于氧化锆纤维编织的自润滑上浆剂耐磨性、断裂强力和剪切性能高，毛丝和断丝的现象显著改善，综合提高了制品在三维织构时的稳定性，具有良好的生物可降解性。
