環(huán)氧樹脂是泛指分子中含有兩個(gè)或兩個(gè)以上環(huán)氧基團(tuán)的有機(jī)高分子化合物，除個(gè)別外，它們的相對分子質(zhì)量都不高。環(huán)氧樹脂的分子結(jié)構(gòu)是以分子鏈中含有活潑的環(huán)氧基團(tuán)為其特征，環(huán)氧基團(tuán)可以位于分子鏈的末端、中間或成環(huán)狀結(jié)構(gòu)。由于分子結(jié)構(gòu)中含有活潑的環(huán)氧基團(tuán)，使它們可與多種類型的固化劑發(fā)生交聯(lián)反應(yīng)而形成不溶、不熔的具有三向網(wǎng)狀結(jié)構(gòu)的高聚物。上海h級環(huán)氧板電木板上海偉奮實(shí)業(yè)有限公司為您提供環(huán)氧板，歡迎新老客戶來電！</p><div
