使得軟、硬單體配比適當(dāng)，才能達(dá)到壓敏膠的粘接性能和內(nèi)聚強(qiáng)度的協(xié)調(diào)與平衡，但對壓敏膠來說，功能單體的選擇也是很重要的，它既能夠增加壓敏膠的內(nèi)聚力，改善與基材的附著力，又提供了進(jìn)一步交聯(lián)的活性基團(tuán)。另外，乳化劑的用量對乳液的穩(wěn)定性有很大影響，當(dāng)乳化劑用量少時乳液在聚合中穩(wěn)定性差，容易發(fā)生破乳現(xiàn)象，隨著乳化利用量的增加，乳液逐步趨向穩(wěn)定。但乳化劑用量過高又會降低壓敏膠的耐水性，而且施膠時泡沫過多，影響施工性能。在實(shí)際應(yīng)用時，一個完整乳液壓敏膠配方中可能還要加入抗凍劑、消泡劑、防霉劑、色漿等等。

根據(jù)使用方法和領(lǐng)域的不同，乳液壓敏膠有不同的性能測試要求。但基本的性能可以大致分為兩類：乳液性能和壓敏膠力學(xué)性能。其中乳液性能是指乳液本身的一些基本性能，如：固含量、pH值、稀釋穩(wěn)定性、機(jī)械穩(wěn)定性、粘度、pH穩(wěn)定性等等。力學(xué)性能是從膠粘劑使用來評價，包括：初粘性、持粘性、180°剝離強(qiáng)度等等，好的壓敏膠應(yīng)該很好地平衡這三大力學(xué)性能。另外還包括施工性能、著色性能等等。 </p> <p> 壓敏膠粘劑步驟方法措施 </p> <p> 試驗(yàn)準(zhǔn)備由于該試驗(yàn)所合成的壓敏膠，在不同原料配比得情況下可以合成性能不同得壓敏膠。應(yīng)為軟單體、硬單體、改性功能單體它們在組成上相互依存相互制約。要平衡壓敏膠的粘附作用、內(nèi)聚力、粘接性能以及耐水性、耐候性、耐溶劑性就必須先確定各種原料得用量比。查閱相關(guān)文獻(xiàn)知：甲基丙烯酸甲酯與丙烯酸丁酯的比例應(yīng)為1：70；丙烯酸羥乙酯與丙烯酸丁酯的比例應(yīng)為1：60；過liu酸銨引發(fā)劑用量定為單體量的0.5%；乳化劑用量達(dá)到CMC值為易為單體的1.5%；保護(hù)膠定位單體量的2.2%。由此確定其油水比為54：46.這樣所制得的產(chǎn)品性能比較平均良好。
