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。
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。
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。
物理性質
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。
