7、有機(jī)化學(xué)專業(yè)碩士論文第一章文獻(xiàn)綜述1.1前言UV（紫外光）固化和EB(電子束)固化統(tǒng)稱輻射固化。UV固化材料是UV固化的涂料、油墨和黏合劑等材料的統(tǒng)稱，UV固化材料的研究和開(kāi)發(fā)不僅豐富了輻射化學(xué)、有機(jī)化學(xué)、高分子化學(xué)和物理等相關(guān)學(xué)科的內(nèi)容，也不僅豐富了生產(chǎn)和日常生活必需品的種類，同時(shí)還能滿足高技術(shù)領(lǐng)域，尤其是微電子材料加工[1]的特殊要求，促進(jìn)了高新技術(shù)的進(jìn)步。UV固化涂料是UV固化技術(shù)應(yīng)用最主要的一部分，近年來(lái)，隨著現(xiàn)代科技的高速發(fā)展，為滿足全球性的環(huán)境保護(hù)的要求，必須限制涂料中揮發(fā)性有機(jī)物的排放，使得紫外光固化技術(shù)的研究開(kāi)發(fā)和應(yīng)用出現(xiàn)了日新月異、

8、迅猛發(fā)展的良好勢(shì)頭。從上世紀(jì)60年代末到80年代末，世界應(yīng)用輻射固化技術(shù)（其中UV固化占90％以上）年平均增
