1、浙江大學(xué)化工系碩士學(xué)位論文鄰甲酚醛環(huán)氧樹脂的制備與性能表征姓名：張學(xué)新申請(qǐng)學(xué)位級(jí)別：碩士專業(yè)：化學(xué)工程指導(dǎo)教師：單國榮20090401浙江大學(xué)工程碩士學(xué)位論文摘要簡單介紹了國內(nèi)外環(huán)氧塑封料行業(yè)的發(fā)展歷史和目前的狀況以及環(huán)氧塑封料對(duì)鄰甲酚醛環(huán)氧樹脂的質(zhì)量指標(biāo)要求。詳細(xì)綜述了國內(nèi)外鄰甲酚醛環(huán)氧樹脂的研究動(dòng)態(tài)和發(fā)展趨勢(shì)、生產(chǎn)現(xiàn)狀、制備方法及原理、性能的影響因素及其應(yīng)用情況。研究了制備鄰甲酚醛環(huán)氧樹脂的原理和制備方法、工藝流程、實(shí)驗(yàn)裝置、中試裝置。對(duì)鄰甲酚醛樹脂、鄰甲酚醛環(huán)氧樹脂的反應(yīng)機(jī)理進(jìn)行了探討，考察了制備過程中影響鄰甲酚醛樹脂、鄰甲酚醛環(huán)
2、氧樹脂性能的各個(gè)因素。對(duì)鄰甲酚醛環(huán)氧樹脂的性能進(jìn)行了表征，制定了產(chǎn)品標(biāo)準(zhǔn)．確定和優(yōu)化了工藝路線。以草酸、鹽酸為催化劑，醛／酚摩爾比在o．85～0．92，反應(yīng)溫度為98"C反應(yīng)，時(shí)間為5小時(shí)，加堿中和催化劑，溶劑莘取，水洗等，合成出合適的鄰甲酚醛樹脂．以適量季銨鹽為催化劑，鄰甲酚醛樹脂于110"(2下與過量環(huán)氧氯丙烷先醚化，然后在60～70"C溫度及．82kPa真空條件下加堿閉環(huán)反應(yīng)，堿的摩爾數(shù)為酚羥基當(dāng)量的1．05，再通過萃取、精制閉環(huán)、洗脫鹽等，合成出高品質(zhì)的鄰甲酚醛環(huán)氧樹脂。根據(jù)小試確定的工藝進(jìn)行了中試，中試產(chǎn)品與國內(nèi)產(chǎn)品進(jìn)行了比較
3、，中試產(chǎn)品送客戶試用，達(dá)到進(jìn)口同類產(chǎn)品水平。關(guān)鍵詞：鄰甲酚醛環(huán)氧樹脂，制備，性能表征浙江大學(xué)工程碩士學(xué)位論文ABSTRACTThehistoryofthedevelopmentandcurrentsituationofmoldingcompoundanditstechnicalrequirementsforo—cresolformaldehydeepoxyresinwasbrieflyintroduced．Theresearchdynamicsanddevelopmenttrendsofo—cresolformaldehydeepoxy
