中文摘要
基于之前DFG研究项目中产生的知识,该知识转移项目旨在与ALBIS PLASTIC GmbH合作开发一种适用的PA6共混物,该共混物在不降低杨氏模量或强度的情况下提高了冲击强度。此外,断裂伸长率应保持在较高水平。达到这一目标将克服通常的限制,即只有当杨氏模量和强度急剧下降时,冲击强度才能增加。这种特殊的性能组合将使新开发的混合物在市场上独一无二。新型PA6材料应由以PA6为基体,分离的有机改性纳米硅酸盐粘土和具有最佳粒径和分布的非交联橡胶组成,以提高强度和刚度。在该项目中,在商用双螺杆挤出机上生产新型共混物具有重要意义。此外,本项目还研究了现有填料模拟模型的改进,该模型适用于宏观填料,并希望使现有模型适用于纳米级填料。这一进展将有助于预测其各向异性,并可用于新型三元共混物的应用。
英文摘要
Based on the knowledge generated in preceding DFG research project, this Knowledge Transfer Project has the aim to develop a applicable PA6 blend, which has increased impact strength without decreasing the Youngs modulus or the strength, in cooperation with ALBIS PLASTIC GmbH. In addition, the elongation of break should stay on a high level. Reaching this aims would overcome the common limitation that the impact strength can only be increased when the Youngs modulus and the strength is drastically decreased. This special combination of properties would make the new developed blend unique in the market. The new PA6 material should consist of a ternary blend, which consists of PA6 as matrix, separated, organic modified nano silicate clays to increase the strength and the stiffness and non-cross-linked rubber with an optimal particle size and distribution to improve the impact strength. In this project it will be important to produce the new blend on commercial twin screw extruders. Furthermore, this project deals with the advancement of the existing filler simulation models, which works well for macroscopic fillers, and wants to adapt the existing models for the use for nanoscale fillers. This advancement should help to predict the anisotropic properties and should be used in the application of the new ternary blend.
