分子鏈中的不飽和雙鍵與交聯(lián)單體（通常為苯乙烯）的雙鍵發(fā)生交聯(lián)聚合反應(yīng)，由線型長鏈分子形成三維立體網(wǎng)絡(luò)結(jié)構(gòu)的過程。在這一固化過程中，存在三種可能發(fā)生的化學(xué)反應(yīng)，即 </p> <p> ①、苯乙烯與聚酯分子之間的反應(yīng)； </p> <p> ②、苯乙烯與苯乙烯之間的反應(yīng)； </p> <p> ③、聚酯分子與聚酯分子之間的反應(yīng)。 </p> <p> 對(duì)于這三種反應(yīng)的發(fā)生，已為各種實(shí)驗(yàn)所證實(shí)。 </p> <p> 值得注意的是，在聚酯分子結(jié)構(gòu)中有反式雙鍵存在時(shí)，易發(fā)生第三種反應(yīng)，也就是聚酯分子與聚酯分子之間的反應(yīng)，這種反應(yīng)可以使分子之間結(jié)合的更緊密，因而可以提高樹脂的各項(xiàng)性能。 </p><p> 不飽和聚酯樹脂作為復(fù)合材料，在涂料、玻璃鋼、人造石、工藝品等領(lǐng)域，都已經(jīng)得到了較好的應(yīng)用。但不飽和樹脂的顏色黃變，一直是一個(gè)困擾生產(chǎn)廠家的問題。通常不飽和樹脂的黃變?cè)虬ㄒ韵聨追N： </p> <p> 1、不飽和樹脂酯化合成過程中，由于高溫引起的熱老化黃變，不飽和樹脂一般酯化溫度，為180～220℃甚至更高，在此溫度下樹脂很容易因熱老化而變黃，影響樹脂產(chǎn)品外觀； </p> <p> 2、樹脂接觸紫外線而引起的黃變，主要因素是樹脂中存在的苯環(huán)(包括芳香族二元酸/酐和苯乙烯引入的苯環(huán))，原因可能是芳香族化合物在高溫時(shí)發(fā)生熱氧降解，容易發(fā)生π→π軌道上的電子躍遷，使樹脂呈現(xiàn)黃色； </p> <p> 3、樹脂生產(chǎn)過程中，因裝置密封性不好等原因使原料接觸氧氣，通用不飽和聚酯分子鏈中不僅含有酯基、羥基、羧基，而且含有雙鍵和芳香環(huán)，微量氧能使其發(fā)生熱氧化降解，**明顯的表現(xiàn)就是樹脂顏色變黃。 </p> <p> 4、添加劑的影響如抗氧劑、阻聚劑、固化劑等，胺類抗氧劑易轉(zhuǎn)變成氮氧自由基而使制品著色，常用的阻聚劑，如對(duì)苯二酚，在微量氧存在時(shí)氧化為醌類，醌類本身帶有顏色，從而影響樹脂的顏色，固化劑有些廠家仍采用過氧化酰類-叔胺體系和過氧化酮類-金屬皂體系，由于叔胺和金屬皂都有顏色，容易使樹脂著色。 </p> <p> <br /> 該階段中，樹脂既不溶解也不熔融。</p><div
