设计了一种新的梯度组分分布数学模型,采用梯度因子和梯度层数控制梯度组分的分布,并采用逐层浇铸的方法制备了不同层数的EP/PU梯度互穿网络聚合物(IPN)材料;测试了材料的拉伸性能、弯曲性能以及冲击性能;研究了梯度层数变化对这些性能的影响,并同普通IPN的性能进行了对比。研究结果表明,在相同质量比和梯度因子情况下,梯度层数越多,拉伸强度和冲击强度越高,弯曲强度越低。梯度IPN的拉伸强度和冲击强度均高于普通IPN,弯曲强度低于普通IPN。 相似文献

Four kinds of polyurethane/polyacrylate interpenetrating polymer networks (crosslinked polyacrylate semi-IPNs, crosslinked polyurethane semi-IPNs, all-IPNs and all-IPNs with opposite charge groups) were synthesized by a simultaneous polymerization process. Their damping properties, mechanical properties and multiphase morphology were investigated by automatic torsional braid analysis, an Instron tester, small-angle X-ray scattering (SAXS) and tranmission electron microscopy (TEM). The results show that the attraction between positively charged groups and negatively charged groups improved the miscibility of the two components. When the weight ratio of polyurethane/polyacrylate was 1:2, the resulting IPN materials possessed better damping and mechanical properties, and the specific surface area reached a maximum. © 1999 Society of Chemical Industry 相似文献

Polystyrene/polyacrylate latex IPN (PS/PA LIPN) was synthesized using two-stage emulsion polymerization. The effects of various polymerization parameters on the damping performance were investigated systematically. The results show that the multicomponent copolymerization favours broadening of the damping temperature range. Changing the sequence of adding raw materials and the amount of crosslinker used enables a great improvement in the compatibility of the two networks. Adding inorganic fillers is an important way of increasing and broadening the damping value. Transmission electron micrographs of PS/PA LIPN show the microscopic morphology of LIPN consistent with the above results. 相似文献

A series of carbon black containing interpenetrating polymer networks (IPNs) based on unsaturated polyester/epoxy (weight ratios 10/90, 20/80, 30/70) were developed. Scanning electronic microscopy exhibits that the compatibility was decreased and the morphology seemed to become less rigid as the content of unsaturated polyester increased in IPNs. The results also indicate that flame retardants were uniformly distributed in the IPN matrices. It is found that the heat resistance, damping, and mechanical properties were all improved simultaneously by adding the plate‐shaped carbon black flame retardants to the unsaturated polyester/epoxy IPNs. © 2002 Wiley Periodicals, Inc.
