【摘要】：長碳鏈聚酰胺基熱塑性彈性體(LCPAE)是一種高性能熱塑性彈性體,它是由長碳鏈聚酰胺(LCPA)硬段以及聚醚軟段構成的一種嵌段共聚物,通過調節(jié)聚酰胺硬段以及聚醚軟段的分子量以及相對含量,可以獲得一系列的嵌段共聚物,邵氏硬度從25D到70D。由于兩種鏈段在熱力學上互不相容,使得該類彈性體具有微相分離的聚集態(tài)結構,同時具備LCPA樹脂耐磨、強度高、熱穩(wěn)定性好、加工性好以及聚醚材料的低溫柔軟性、回彈性高等諸多優(yōu)點。本文綜述了1970年以來LCPAE的發(fā)展歷程、市場現狀、國內外研究進展以及相關專利分析,并簡要總結了借助原位X射線衍射技術研究LCPAE微觀結構與性能的部分進展,其在單軸拉伸外場作用下的聚集態(tài)結構演化對于理解其結構性能關系、指導分子結構設計有著重要意義。本文還簡要介紹了本實驗室使用具有自主知識產權的長碳鏈聚酰胺PA1012原料設計合成系列LCPAE的工作。文章最后結合已有研究進展,對LCPAE面臨的重要科學問題以及產學研協作實現國產化所需解決的實際問題進行了總結與展望。
[Abstract]:Long chain polyamide based thermoplastic elastomer (LCPAE) is a kind of high performance thermoplastic elastomer. It is a block copolymer composed of long chain polyamide (LCPA) hard segment and polyether soft segment. A series of block copolymers can be obtained by adjusting the molecular weight and relative content of hard and soft segments of polyamide and polyether. The hardness of the block copolymers ranges from 25D to 70D. Due to the thermodynamics incompatibility of the two segments, the elastomer has a microphase separated aggregate structure, a high wear resistance, high strength, good thermal stability, good processability and low temperature softness of the polyether material. High resilience and many other advantages. This paper reviews the development of LCPAE since 1970, market status, domestic and international research progress and related patent analysis, and briefly summarizes some progress in studying the microstructure and properties of LCPAE by means of in situ X-ray diffraction technique. The evolution of the aggregate structure under uniaxial tension is of great significance in understanding the relationship between structure and properties and guiding the design of molecular structure. This paper also briefly introduces the design and synthesis of a series of LCPAE using long carbon chain polyamide PA1012 with independent intellectual property rights in our laboratory. Finally, combined with the existing research progress, the paper summarizes the important scientific problems faced by LCPAE and the practical problems that need to be solved in order to realize the localization of LCPAE.
