Hdt of the polybenzoxazine ( bisphenol a type ) / phlogopite composites not changed in the range of phlogopite content from 0 % to 15 % 多元酚型ben蛙石插层纳米复合物固化后,其热稳定性明显提高。

As the content of the expanded vermiculite was 20 % , the tonset of the polybenzoxazine ( mulitphenol type ) / vermiculite hybrid nanocomposites from its tga cure was 35 chigher than that of the polybenzoxazine ( mulitphenol type ) / phlogopite composites 膨胀蛙石含量为20时,插层纳米固化物的起始热分解温度高于金云母的约35t 。
5.
Mechanics properties and heat resistant properties of the polybenzoxazine ( bisphenol a type ) / vermiculite hybrid nanocomposites were lower than those of the polybenzoxazine ( bisphenol a type ) but prior to those of the polybenzoxazine ( bisphenol a type ) / phlogopite composites 这些分析表明:双酚a型ben蛭石的固化结构为固化不完全的交联密度更低的聚合网络结构。

Secondly , based on the microbeam analytical technique , on the one hand , through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand , through multi - point analysis of a part of the minerals from mantle , the auther got dynamic information from mantle . finally , generalizating the fruits of this study and predecessors , the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites , clinopyroxenites , websterite , dunite , harzburgites , garnet lherzite , phlogopite lherzite , eclogites , clinopyroxene megacrysts ; compared with east china and north china platform , the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the . upper mantle beneath north hetian area is heterogeneous , with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204 . 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits 最后,综合本区幔源矿物和地幔岩石的特征以及地球物理资料,得出如下结论:本区上地幔的物质组成有尖晶石二辉橄榄岩、二辉岩、单斜辉石岩、纯橄榄岩、方辉橄榄岩、石榴石二辉橄榄岩、金云母二辉橄榄岩、榴辉岩;与中国东部以及华北地台上地幔相比,研究区上地幔具有富集主元素中相容元素和亏损其中的不相容元素的特征,局部熔融程度较高;上地幔存在横向和纵向的不均一性,从西部的克里阳到喀拉喀什河和玉龙喀什河流域, al和lree富集程度呈下降趋势,不同来源的相同矿物中主元素的含量差异较大;地质历史时期这里可能发生过地壳俯冲并产生壳幔混合作用;玄武岩浆的起源深度73km ;从幔源重砂矿物的温压估算结果,可以推断出岩石圈厚度可达204 . 9km ;综合岩石圈物质组成特征、岩石圈热状态、地幔温压状态、氧逸度以及幔源岩石和幔源矿物的化学成分,认为研究区具备了金刚石成矿地幔地质条件。

Polybenzoxazine / vermiculite hybrid nanocomposites were prepared from two kinds of polybenzoxazine precursors and two kinds of organically modified - vermiculite minerals and expanded - vermiculite which were consisted of vermiculite , hydrobiotite and phlogopite . after treatment of vermiculite minerals by hexadecyl trimethylam monium bromide ( ctab ) , the d001 of vermiculite layers of vermiculite mineral increased from 1 . 43nm to 2 . 67nm and developed a d002 = 1 . 34nm 本文分析了蛭石精矿和膨胀蛭石的组成和结构,用十六烷基三甲基溴化铵( ctab )进行了有机化处理,再通过熔融或溶液混合插层苯并嗯嗪树脂( ben )制备了ben插层蛭石纳米复合材料,并采用蒙脱土进行了对照实验。

When the content of vermiculite minerals was about 10 % , the impact strength ( nick ) and the flexural strength had maximum value , but those of the polybenzoxazine ( bisphenol a type ) / phlogopite composites had been going down . as the content of vermiculite minerals was over 5 % . hdt of the polybenzoxazine ( bisphenol a type ) / vermiculite hybrid nanocomposites was higher than that of the polybenzoxazine ( bisphenol a type ) 4几插层状分散的10蛙石含量的纳米复合材料的物理交联作用表现较为明显,力学性能处于峰值; hdt高于纯树脂,并随含量的增加而提高,含金云母的复合材料的hdt则不随其含量变化而变化。
