聚醚酰亞膠 的英文怎麼說
中文拼音 [jùmíyǎjiāo]
聚醚酰亞膠
英文
pei polyether imide-
An excellent adhesive was prepared from bismaleimide ( bmi ), epoxy resin ( e - 51 and tde - 85 ), 4, 4 ' - diaminodiphenyl sulfone ( dds ) in this thesis. the influence of liquid rubber and polymer ether imide ( pei ) on the properties ( especially high - temperature strength and the peeling strength ) were discussed, their different toughening characteristics and mechanisms were discussed. last, the process and effection of heat - resisted structural adhesive were studied by adhesive experiment of synchronizer in automobile. the results of investigation made clear : the adhesive, has good properties, especially heat - resisted properity
根據材料分子設計的原理，研究了二苯甲烷雙馬來酰亞胺（ bmi ） 4 ， 4 』 ?二胺基二苯基碸（ dds ） e ? 51 tde ? 85組成的環氧膠粘劑體系，研究該體系在作為高溫結構膠粘劑使用時的粘接性能；然後研究了用無規羧基液體丁腈橡膠（ ctbn ? x ）和聚醚酰亞胺（ pei ）分別來增韌該體系的增韌效果；最後通過碳纖維耐磨材料與同步器圓錐環的粘接實驗，研究了耐高溫結構膠粘劑的粘接工藝和使用效果。When change the component of adhesive its shear strength increased from 39. 3 mpa to 53. 5 mpa at room temperature and it have long - term usage at 180 with 25 mpa and can be served at 230 in short period. the addition of liquid rubber resulted in a 300 % increase in the peeling strength. the addition of polymer ether imide led to a 260 % increase in the peeling strength, a 15 % increase in shear strength and a 10 increase in tg ( tg = 195. 54 )
研究結果表明： bmi dds e ? 51 tde ? 85組成的膠粘劑體系的室溫剪切強度為39 . 3mpa ，當改變環氧樹脂的含量時，剪切強度提高到53 . 5mpa ；用無規羧基液體丁腈橡膠改性環氧樹脂膠粘劑時室溫剝離強度提高3 . 0倍；用聚醚酰亞胺改性環氧樹脂膠粘劑，室溫剪切強度最高可達45 . 2mpa ，剝離強度提高2 . 6倍，玻璃化轉變溫度tg = 195 . 54 ，比未增韌體系提高10以上；碳纖維耐磨材料與同步器圓錐環的粘接實驗結果表明，膠粘劑的使用工藝性能良好，滿足室溫剪切強度30mpa和180剪切強度12 . 5mpa的技術要求。
