【摘要】：室溫自交聯(lián)的核殼乳膠粒子的結(jié)構(gòu)設(shè)計(jì)和合成是近年來乳液聚合的主要研究方向之一。隨著人們的環(huán)保意識(shí)不斷增強(qiáng),水性油墨,這一不同于傳統(tǒng)溶劑型油墨的新型油墨品種越來越受到人們的重視。在食品包裝領(lǐng)域,特別是塑料薄膜基材的包裝領(lǐng)域,水性油墨的應(yīng)用已經(jīng)成為大勢(shì)所趨。但是,我國(guó)塑料薄膜印刷用水性油墨發(fā)展起步晚,基礎(chǔ)差,目前市場(chǎng)上主要產(chǎn)品以及相關(guān)核心技術(shù)基本依賴國(guó)外進(jìn)口。針對(duì)目前國(guó)內(nèi)水性油墨的發(fā)展現(xiàn)狀,本課題旨在研發(fā)能滿足市場(chǎng)需求,可以替代進(jìn)口乳液的高性能水性油墨,形成具有自主知識(shí)產(chǎn)權(quán)的水性油墨技術(shù),填補(bǔ)目前國(guó)內(nèi)水性油墨領(lǐng)域的技術(shù)空白。 本論文首先設(shè)計(jì)并合成了室溫自交聯(lián)核殼結(jié)構(gòu)的苯丙乳液,并使用原子力顯微鏡(AFM)、差示掃描量熱儀(DSC)、透射電子顯微鏡(TEM)、傅立葉紅外測(cè)試儀(FTIR)等儀器對(duì)乳膠粒子進(jìn)行了表征。系統(tǒng)地研究了雙丙酮丙烯酰胺(DAAM)／己二酰肼(ADH)交聯(lián)體系的核殼乳液的性能及其影響因素；研究了乳化劑類型和用量,共聚單體的類型和用量對(duì)乳液性能的影響,以及“軟核硬殼”結(jié)構(gòu)乳膠粒子的核殼比對(duì)其膠膜性能的影響,最終通過系統(tǒng)地優(yōu)化乳液聚合的配方與工藝,制備出具有優(yōu)良成膜性能和應(yīng)用性能的丙烯酸樹脂乳液。然后以該乳液作為連接料,研究適用于BOPP、PE、PA、PET等柔性塑料薄膜基材凹版印刷用的水性油墨配方工藝。通過配方工藝研究和優(yōu)化,制備得到的水性油墨在多種塑料薄膜基材(BOPP膜、PE膜、PET膜、PA膜)上均具有出色的附著力、耐水性、干燥速度、復(fù)溶性等性能。完全滿足相關(guān)企業(yè)的實(shí)際使用要求。
[Abstract]:The structural design and synthesis of the room temperature self - crosslinking core - shell latex particles is one of the main research directions of emulsion polymerization in recent years . As people ' s environmental protection consciousness is constantly increasing , the application of water - based ink is becoming more and more important in the field of food packaging , especially in the packaging of plastic film substrates .

In this paper , we designed and synthesized styrene - acrylic emulsion with room temperature self - crosslinking core - shell structure , and characterized the latex particles by means of atomic force microscopy ( AFM ) , differential scanning calorimetry ( DSC ) , transmission electron microscope ( TEM ) and Fourier infrared detector ( FTIR ) . The properties and influencing factors of the core - shell emulsion of diacetone acrylamide ( DAAM ) / adipic dihydrazide ( ADH ) crosslinking system were studied systematically .
The paper studied the influence of the type and dosage of emulsifier , the type and dosage of comonomer on the properties of emulsion and the influence of core - shell ratio of " soft - core hard shell " structure latex particles on the properties of the film . Finally , by systematically optimizing the formulation and process of emulsion polymerization , the water - based ink formulation with excellent film - forming performance and application performance was prepared .
