不飽和聚酯樹脂的固化是游離基引發(fā)的共聚合反應(yīng)，如何能使反應(yīng)啟動是問題的關(guān)鍵。單體一旦被引發(fā)，產(chǎn)生游離基，分子鏈即可以迅速增長而形成三向交聯(lián)的大分子。 </p> <p> 不飽和聚酯樹脂固化的啟動是首先使不飽和 C—C 雙鍵斷裂，由于化學(xué)鍵發(fā)生斷裂所需的能量不同，對于 C—C 鍵，其鍵能 E=350kJ/mol，需 350-550℃的溫度才能將其激發(fā)裂解。 </p> <p> 顯然，在這樣高的溫度下使樹脂固化是不實用的。因此人們找到了能在較低的溫度下即可分解產(chǎn)生自由基的物質(zhì)，這就是有機過氧化物。一些有機過氧化物的 O—O 鍵可在較低的溫度下分解產(chǎn)生自由基。其中一些能在 50-150℃分解的過氧化物對樹脂的固化很有利用價值。我們可以利用有機過氧化物的這一特性，選擇其中的一些作為樹脂的引發(fā)劑，或稱固化劑。在這一固化過程中，存在三種可能發(fā)生的化學(xué)反應(yīng)。崇左質(zhì)量好固化劑</p><p style="text-indent:25px">然后常溫養(yǎng)護 24 小時后再投入使用。崇左質(zhì)量好固化劑</p><p>
