摘要

摘要: 以聚醚醇与二异氰酸酯为主要原料、N-甲基二乙醇胺（MDEA）为亲水扩链剂合成了应用于连续玄武岩纤维浸润剂中主成膜剂的水性聚氨酯。采用激光粒度仪、热失重分析仪等表征了水性聚氨酯粒径大小、热力学性能等；用傅里叶红外光谱仪、万能试验机、扫描电镜等表征了浸润剂处理前后连续玄武岩纤维的表面化学元素组成、力学性能、表面形貌变化等。探究了MDEA质量分数（w（MDEA））对水性聚氨酯以及连续玄武岩纤维性能的影响，以及浸润剂处理前后的连续玄武岩纤维耐酸、碱性等。结果表明，当w（MDEA）=6.0%时，水性聚氨酯稳定性较好，浸润剂处理过的连续玄武岩纤维断裂强度提升了75%，耐酸、碱腐蚀性明显增强。

Abstract: Water-soluble polyurethane was synthesized by using polyether polyol and diisocyanate as the main raw materials, small molecule diol and methyl pyrrolidone as auxiliary raw materials, and N-methyl diethanolamine (MDEA) as a hydrophilic chain extender, and the synthesized polyurethane was coated on continuous basalt fibers as a film-forming agent. The properties of water-soluble polyurethane and continuous basalt fibers were studied. The most suitable water-soluble polyurethane was selected as the film-forming agent for the infiltrate. Water contact angle tester, laser particle size analyzer and thermal weight loss analysis were used to study the storage stability, water contact angle, particle size and thermodynamic properties of water-soluble polyurethanes. Fourier infrared spectroscopy, universal testing machine and scanning electron microscopy were used to characterize the chemical elemental composition of continuous basalt fiber surfaces before and after polyurethane treatment. Mechanical properties and surface morphology were also investigated. The continuous basalt fibers before and after the infiltrate treatment were also subjected to acid and alkali treatment to observe the fracture strength retention and mass retention of the fibers. Results showed that when the mass fraction of MDEA (w(MDEA)) was 6.0%, the waterborne polyurethane had good stability, uniform particle size distribution and ideal water resistance. The fracture strength of continuous basalt fibers treated with sizing agent was increased by 75%, and the toughness was similarly improved. After acid-base treatment, the fiber breaking strength retention and quality retention were significantly increased.
