摘要:
文以直径为12 nm的SiO2粒子作为分散相,PEG 200作为分散介质,通过机械搅拌和超声振荡的方法分别制备出20%、22%、24%、26%、28%五种质量分数的剪切增稠液(STF)体系。并对纳米SiO2粒子的外观形貌及团聚情况STF的稳态流变性能进行了测试并将STF与涤纶织物复合进行防刺实验。结果表明,纳米SiO2粒子的团聚现象明显,部分团聚体呈现网状结构;STF的粘度黏度随着剪切速率的增加呈现先变稀、再增稠的现象,表现为非牛顿流体特性;STF的临界粘度黏度随着纳米SiO2粒子浓度的增加而增加;STF有利于提高涤纶织物的防刺性能。
Abstract:
Nano-SiO2 particles with diameter of 12 nm were used as dispersed phase and PEG 200 as dispersed medium in the paper. Shear thickening fluid (STF) system was prepared by mechanical stirring and ultrasonic shock with mass fraction of 20%, 22%, 24%, 26% and 28%.The morphology and agglomeration of nano-SiO2 particles, and the steady-state rheological properties of STF were tested.STF and polyester/cotton fabric composite to anti-perforation test.The results show that the agglomeration of nano-SiO2 particles was obvious, and some of the aggregates showed a network structure. The viscosity of STF exhibited firstly thinning and secondly thickening with the increase of shear velocity, which manifested as non-Newtonian fluid properties. The critical viscosity of STF increased with the increase of nano-SiO2 particles’ concerntration. STF are benefit to improve stab-resistant properties of polyester fabrics
