硅酸鈉能使軟木粉粘結在模具表面,而且還有助於軟木粉耐受熔融鉛合金的碳化作用。Study on the preparation and relationship between micro - structure and mechanical properties of epoxy / rubber / clay composites epoxy / rubber / clay composite has been prepared by the melted intercalation of octadyl ammonium exchanged montmorillonite ( c18 ) with dgeba and carboxyl - terminated butadiene - acrylonitrile random copolymers ( ctbn ), and piperidine as the curing agent
環氧樹脂橡膠粘土三元復合材料採用熔融共混法制備了環氧樹脂橡膠粘土三元復合材料,就ctbn 、 c18含量、加料順序和固化工藝等制備工藝對c18在三元復合材料結構以及材料的力學性能的影響進行了研究。Study on the optical properties of transparent epoxy / clay nanocomposites a new type transparent epoxy based nanocomposites has been prepared by the reaction of alkylammonium exchanged montmorillonite ( amt ) with diglycidyl ether of bisphenol a ( dgeba ) and triethylamine as the curing agent. the morphology of amt in the epoxy matrix was characterized with x - ray diffraction ( xrd ), scanning electron microscopy ( sem ) and transmission electron microscopy ( tem )
光學透明環氧樹脂粘土納米復合材料光學性能採用十八烷基伯胺鹽、十六烷基三甲基溴化胺處理na基蒙脫土製備出兩種不同的有機土,以三乙胺為固化劑,有機土與雙酚a型環氧樹脂熔融插層聚合后制備出剝離型和插層型兩種結構的環氧樹脂粘土納米復合材料。Second, ptfe composites were treated using different surface treatment methods. the adhesive strength tests were conducted by a standard experiment method. the maximum adhesive strength between ptfe and stainless steel was up to 5. 63 mpa using the melting potassium acetate
利用不同的表面處理方法對ptfe進行表面改性,然後按標準試驗方法進行粘接強度試驗,結果表明,經過熔融醋酸鉀處理的ptfe與鋼的粘接強度最高,達到5 . 6mpa 。Secondly, the intercalation and exfoliation behavior of two layered silicates modified by organic cation ( dk1 and dk3 ) with the resol under different conditions is investigated. it is found that the intercalated structure of dk3 is preserved and exfoliated in cured rplsn, while the resol intercalated in dk1 is deintercalated when it is cured. it is suggested that dk3 intercalated in the resol is more stable in the curing process than dk1
結果表明, dk3在樹脂中較為穩定,能形成剝離型納米復合材料,而dk1在樹脂中不穩定,固化后, d _ ( 001 )反而會有所減小;兩者插入過程都非常快;對dk3來說,在合成樹脂過程中立即加入粘土和將樹脂與dk3進行直接熔融插層的效果差別不大。In this thesis, pvc / organoclay nanocomposites were synthesized by in - situ intercalation and melt - blending intercaltion. the structure and properties of the composites were investigated. furthermore, some factors, such as special synthesis method, the different clay surface modifiers and the molecular weight of the polymer matrix which can be affect the intercalation results, were discussed
本文分別通過原位插層法和熔融插層法制備了聚氯乙烯粘土納米復合材料,通過插層結構和復合材料性能的對比,得出一系列有意義的結論;並研究了粘土表面修飾劑、插層方法以及樹脂基體分子量對插層結構的影響。The structure of the composites was characterized by x - ray diffraction and transmission - electric microscope. the experimental results showed that the in - situ intercalation realized much finer dispersion of the silicate layers in the pvc matrix than the melt - blending intercalation. as for as the properties of the composites, the well - dispersed organoclay in the composites improved the properties of the materials, especially for the viscat softing temperature
本文主要通過x射線衍射、透射電子顯微鏡對復合材料的結構進行表徵,結果證明:原位插層復合材料中粘土片層基本剝離,均勻的存在於聚氯乙烯樹脂基體中;熔融插層體系中粘土的分散狀態明顯劣於原位插層體系,粘土以一定量片層堆積的形式存在。分享友人
