【摘要】：長(zhǎng)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(zhǎng)碳鏈聚酰胺(LCPA)硬段以及聚醚軟段構(gòu)成的一種嵌段共聚物,通過調(diào)節(jié)聚酰胺硬段以及聚醚軟段的分子量以及相對(duì)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(xué)上互不相容,使得該類彈性體具有微相分離的聚集態(tài)結(jié)構(gòu),同時(shí)具備LCPA樹脂耐磨、強(qiáng)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(diǎn)。本文綜述了1970年以來LCPAE的發(fā)展歷程、市場(chǎng)現(xiàn)狀、國(guó)內(nèi)外研究進(jìn)展以及相關(guān)專利分析,并簡(jiǎn)要總結(jié)了借助原位X射線衍射技術(shù)研究LCPAE微觀結(jié)構(gòu)與性能的部分進(jìn)展,其在單軸拉伸外場(chǎng)作用下的聚集態(tài)結(jié)構(gòu)演化對(duì)于理解其結(jié)構(gòu)性能關(guān)系、指導(dǎo)分子結(jié)構(gòu)設(shè)計(jì)有著重要意義。本文還簡(jiǎn)要介紹了本實(shí)驗(yàn)室使用具有自主知識(shí)產(chǎn)權(quán)的長(zhǎng)碳鏈聚酰胺PA1012原料設(shè)計(jì)合成系列LCPAE的工作。文章最后結(jié)合已有研究進(jìn)展,對(duì)LCPAE面臨的重要科學(xué)問題以及產(chǎn)學(xué)研協(xié)作實(shí)現(xiàn)國(guó)產(chǎn)化所需解決的實(shí)際問題進(jìn)行了總結(jié)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.
