【摘要】 用环氧树脂、氨基聚丁二烯(ATB)和氨基丁腈(ATBN)、三乙烯四胺制备了软段含量从59%至82%的ATB/ATBN系列试样。利用DMA、应力-应变、SEM等方法研究系列试样低温性质,并且在恒应变下进行了DMA验证。结果表明,环氧树脂与ATB/ATBN能在广泛的比例反应,具有两相结构。软段Tg不随软段含量变化,而硬段Tg随硬段含量变化,这是由于本文设计的配比,软段均为连续相,硬段以微畴分散在连续相中所致。ATB系列因软硬段相互作用弱,ΔTg (Tg1-Tg2)宽,在宽温域模量为一平台,在平台区里,低拉伸率下,应力变化小,在低温(可达-70-C)仍能保持弹性材料的特征。环氧增强的ATB和ATBN都可以作为低温弹性材料使用。在上述研究的基础上,用环氧树脂、氨基聚丁二烯(ATB)和丙烯腈含量不同的氨基丁腈(ATBN).三乙烯四胺制备了丙烯腈含量为0、10%、18%、26%的ATBN试样。利用DMA、应力-应变、吸水率、压缩永久形变、溶胀度以及溶出率考察环氧增强不同丙烯腈含量的ATBN性质,以便指导其在特殊环境下的工业应用和操作。结果表明,不同丙烯腈含量的ATBN性能差异较大,可根据环境的需要选择使用不同含量的丙烯腈的ATBN。更多还原

【Abstract】 series of the amine-terminated poly-butadiene/amine-terminated butadiene acrylonitrile (ATB/ATBN) samples with the soft segment content from 59% to 82% were prepared on the basis of E-51, ATB, ATBN and triethylenetetramine.The DMA, SEM, Strain-stress were used to study the properties of the samples at low temperature. The result shows that epoxy resin and ATB/ATBNcan react in a wide range of proportion,with two phase structure. The Tg of soft segment does not change with soft segment content, but the Tg of hard segment changes with hard segment content. The modulus is a platform in the wide temperature rangeof ATB samples, it can still maintain the characteristics of elastic material at low temperatures (up to-70 ℃).ATB and ATBN can be used as elastic material at low temperature.On the basis of the above research,the acrylonitrile content of 0,10%,18%,26% ATBN sampleswere prepared on the basis of E-51,Amine-terminated poly-butadiene (ATB), Triethylenetetramine (TETA) and Acrylonitrile content in differentAmine-terminated butadiene acrylonitrile(ATBN).The DMA,Strain-stress,Water absorption, compression permanent deformation, swelling degree and the dissolution ratewere used to study the properties of the samples, in order to guide the industrial application and operationUnder the special environment.The results showed that different ATBN performance differences of acrylonitrile content.According to the need of the environment, choose to use different content of acrylonitrile ATBN更多还原
