不飽和聚酯樹脂的固化，是指樹脂從液態(tài)轉(zhuǎn)變?yōu)楣虘B(tài)的過程，這是用不飽和聚酯樹脂制造產(chǎn)品的必經(jīng)過程。這個過程可以在加熱加壓下完成，也可以在不經(jīng)加熱的情況下完成（冷固化）。從表面上看，是從可流動的液體變成堅硬的固體，但從化學(xué)上看，是從線型分子結(jié)構(gòu)轉(zhuǎn)變成體型分子結(jié)構(gòu)的過程。 </p> <p> 常用的不飽和聚酯樹脂主要由線型不飽和樹脂和活性單體（一般是苯乙烯）兩部分組成。兩者都含有不飽和鍵，在一定的條件下（例如加入過氧化物引發(fā)劑、加熱、受紫外線照射等），就能進(jìn)行自由基共聚和反應(yīng)。這種反應(yīng)實在按照鏈引發(fā)、鍵增長和鏈終止的歷程進(jìn)行的。在這一過程中伴隨著熱量的放出，液體樹脂的粘度迅速增大，硬度提高，**終變成了既不溶解也不熔融的固體。根據(jù)需要在成型過程中可以加入增強(qiáng)材料如玻璃纖維，也可以不加增強(qiáng)材料，只加（或不加）不同的填料，前者即得到我們通常所說的玻璃鋼，后者可以制成人造大理石，人造瑪瑙等制品或作為表面涂層使用潮州定制固化劑批發(fā)拉伸強(qiáng)度和斷裂延伸率的比較大值出現(xiàn)在樹脂固化度為
