  • 網絡擴展資料

    不飽和聚酯樹脂(Unsaturated Polyester Resin,簡稱UPR)是一種熱固性高分子化合物,主要由不飽和二元酸(如馬來酸酐)與二元醇(如乙二醇)縮聚反應生成,并加入乙烯基單體(如苯乙烯)作為交聯劑。

    核心特點與組成

    1. 化學結構
      分子主鍊含重複的酯鍵和不飽和雙鍵,通過縮聚反應形成線型聚合物。不飽和雙鍵賦予其高反應活性,可與交聯劑發生自由基共聚反應,形成三維網狀結構。

    2. 固化過程
      在引發劑(如過氧化物)作用下,雙鍵與乙烯基單體交聯,形成不溶不熔的固體。固化時伴隨收縮,收縮率較大,需通過填料或工藝優化改善。

    3. 物理性質

      • 相對密度:1.11~1.20
      • 介電性能良好,適合電氣絕緣材料
      • 耐化學腐蝕和耐熱性較強。

    應用領域

    主要用于複合材料(如玻璃鋼)、塗層、人造石材、汽車零部件及電子封裝材料。其液态特性便于塗覆和成型,固化後機械強度高。

    優缺點
