摘要:
本文通过氢氧化铝填料改善改性不饱和聚酯树脂材料(PUP)性能。研究发现氢氧化铝添加量和颗粒粒径大小会直接影响相应树脂体系粘度、最终材料的力学性能、热稳定性和电学绝缘性能。通过控制氢氧化铝填充量及粒径大小,可明显提高相应材料的力学性能、热稳定性和电绝缘性且能维持树脂体系低粘度。借助扫描电子显微镜研究了材料两相界面分布,探讨了氢氧化铝颗粒影响改性不饱和聚酯材料性能的机理。

Abstract:
The performance of the modified unsaturated polyester was improved by aluminum hydroxide filler in the research. Studies found that the viscosity of the resin system, mechanical properties, thermal stability and electrical insulativity of final materials were affected by the filling content and particle sizes of aluminum hydroxide directly. With proper particle diameter and filling content, aluminum hydroxide particles could apparently improve the mechanic property, thermal stability and electrical insulativity of corresponding materials in sone extent, meanwhile the viscosity of the resin system would keep low. The mechanism of the influence of aluminum hydroxide on the performance of modified unsaturated polyester was studied by the fracture morphology of samples scanned by scanning electron microscopy.
