  • 專業解析

    不飽和聚酯(unsaturated polyester)是一類由不飽和二元酸(或酸酐)與二元醇通過縮聚反應生成的線性高分子化合物。其分子鍊中含有不飽和雙鍵結構,可通過自由基聚合反應與乙烯基單體(如苯乙烯)交聯固化,形成三維網狀結構的熱固性材料(美國化學會《化學與工程新聞》)。

    從化學組成來看,典型的不飽和聚酯由順丁烯二酸酐(馬來酸酐)與丙二醇縮合而成,雙鍵的存在使其具備後續交聯能力。固化過程需要過氧化物引發劑(如過氧化甲乙酮)和促進劑(如環烷酸钴)的共同作用,該特性被廣泛應用于複合材料制造領域(《材料科學進展》期刊)。

    在工業應用中,不飽和聚酯樹脂主要作為基體材料用于:

    1. 玻璃纖維增強塑料(FRP)制品,占全球用量的60%以上
    2. 人造石材表面塗層
    3. 汽車零部件模壓成型
    4. 船舶防腐層構建 其優勢在于固化收縮率低(0.5%-1.2%)、機械強度高且成本效益顯著(國際複合材料協會技術白皮書)。

    需要注意的是,未固化樹脂含有苯乙烯等揮發性有機物,操作時需符合OSHA規定的暴露限值(8小時TWA 50ppm)。近年研究顯示,通過添加納米粘土等改性劑可提升制品的阻燃性和尺寸穩定性(《高分子材料科學與工程》年度綜述)。

    網絡擴展資料

    unsaturated polyester(不飽和聚酯)是一種高分子化合物,主要用于制造熱固性樹脂材料。以下是詳細解釋:

    1.基本定義

    不飽和聚酯是由不飽和二元酸(或酸酐)與二元醇通過縮聚反應形成的線型聚合物,其分子鍊中含有酯鍵和不飽和雙鍵。這種結構使其能夠通過雙鍵與其他單體(如乙烯基單體)發生交聯固化反應,形成三維網狀結構的高分子材料。

    2.化學特性

    3.應用領域

    4.相關術語

    不飽和聚酯的核心特點是其分子中的不飽和雙鍵,使其可通過交聯反應形成堅固的熱固性材料,廣泛應用于工業和複合材料領域。如需更專業的技術參數,可參考化學材料手冊或行業标準。
