CPE增容PVC／SBS共混体系的研究

通过冲击试验、应力－应变试验、动态力学分析（ＤＭＡ）、扫描电镜（ＳＥＭ）及光学显微镜观察，研究了ＣＰＥ增容的ＰＶＣ／ＣＰＥ－ＳＢＳ共混物的性能与形态结构之间的关系。实验结果表明，ＣＰＥ对ＰＶＣ与ＳＢＳ共混体系有很好的增容作用，ＣＰＥ与ＳＢＳ在一定组成范围内对ＰＶＣ增韧具有协同效应，大幅度地提高共混物的抗冲击性能。

Thermoelastoplastic Deformation Analysis of Electromechanical Equipments under Electrocaloric Shock

A coupled thermomechanical model is presented to investigate the thermoelastoplastic deformation mechanism of electromechanical equipments under the condition of electrocaloric shock. In the coupling model, differentiating from the previous analyzing viewpoint that looked upon deformation work as additional heat source, temperature-field equation is established by considering the weakening role of deformation work on the intensity of internal heat source; in the process of setting up displacement-field equation, G-derivative of nonlinear functional is introduced into the traditional theory of elastoplastic finite deformation to simplify the expression of structural stiffness; stress-field equation is constructed by using the least square method to improve the stress solution obtained by constitutive equation. The presented model is converted into finite element program to simulate deforming process of 3-D structures with temperature-dependent material properties. As an example, thermal deformation analysis of Shanghai metro cars’ brake resistor is performed and compared with experimental results for illustrating the validity of the presented model.

第三代HDPE大口径双壁波纹管增强增韧母料的研制与应用

如何提高HDPE大口径双壁波纹管增强母料的问世，环刚度可以提高了。但是管材的韧性下降了。利用最新的热塑性弹性体改性技术，利用有机包覆、三元共混理论，我们研制和生产出第三代HDPE波纹管增强、增韧母料，不仅提高环刚度使管材环刚度提高到S2=8以上，同时还相应减小冲击强度，断裂伸长率的下降已经在众多管材厂家得到应用。这是塑料改性在塑料管材行业上应用所取得的成功经验。

动态硫化技术

动态硫化是开发橡塑共混材料的一项新技术，所得的产物被称为“硫化共混型热塑料弹性体”或“共混型热塑性硫化胶”。两种材料先经高剪切、高效分散的混炼机械（密炼机、螺杆混合机），然后在动态条件下实现“就地硫化”，从而扶得“共混型热塑性硫化胶”。
