1、五邑大學(xué)本科畢業(yè)設(shè)計(jì) 五邑大學(xué)本科畢業(yè)設(shè)計(jì)(論文 論文)I摘要 摘要本文主要針對(duì)目前市場(chǎng)上仍沒(méi)有綜合性能十分完善的聚氨酯水性涂料， 單純的水性聚氨酯在性能上還不能滿足人們的需求，利用環(huán)氧樹脂出色的粘接能力、高模量、高強(qiáng)度、優(yōu)良的附著力、低收縮率和耐水、耐化學(xué)性好等優(yōu)點(diǎn)以及丙烯酸樹脂較好的耐水性、保色性、物理機(jī)械性能和耐候性能且成本低廉的特點(diǎn)， 通過(guò)接枝共聚方式將這兩種樹脂引入水性聚氨酯鏈段中，對(duì)水性聚氨酯進(jìn)行改性。文中通過(guò)以甲苯二異氰酸

2、酯（TDI） 、聚醚多元醇（PPG220） 、二羥甲基丙酸(DMPA)、三羥甲基丙烷(TMP)、 乙二胺(EDA)、 環(huán)氧樹脂 （E-44） 、 2-乙烯氧甲基-2-羥甲基丁醇(TMPME)和丙烯酸 (MMA、 BA、 AA)混合單體等為主要原料，通過(guò)自乳化法合成了以環(huán)氧樹脂(E-44)改性的水性聚氨酯乳液，在環(huán)氧樹脂改性水性聚氨酯的基礎(chǔ)上，利用丙烯酸酯進(jìn)一步改性。最終得到性能優(yōu)良的改性聚氨酯乳液。 研究了多個(gè)化學(xué)組分對(duì)乳液粘度、穩(wěn)定性

3、的影響以及對(duì)膜機(jī)械性能、耐介質(zhì)性能的影響。關(guān)鍵詞：水性聚氨酯；改性；丙烯酸酯；環(huán)氧樹脂五邑大學(xué)本科畢業(yè)設(shè)計(jì) 五邑大學(xué)本科畢業(yè)設(shè)計(jì)(論文 論文)III目錄摘要·······················
